-# CLAUDE.md - Pattern ADHD Cognitive Support System
-
-⚠️ **CRITICAL WARNING**: DO NOT run `pattern-cli` or any agent commands during development!
-Agents are currently running in production. Any CLI invocation will disrupt active agents.
-Migrations and testing must be done offline after stopping production agents.
-
-Pattern is a multi-agent ADHD support system inspired by MemGPT's architecture to provide external executive function through specialized cognitive agents.
-
-## Project Status
-
-**Current State**: Core multi-agent framework operational, expanding integrations
-
-### 🚧 Current Development Priorities
-
-1. **Backend API Server** - 🟡 ACTIVE DEVELOPMENT

-   - Needs testing with real MCP servers
-   - Auth support may need improvements
-
-4. **Task Management System** - 🟢 QUEUED
-   - Database schema exists
-   - Need CLI commands and user-facing features
-   - ADHD-aware task breakdown planned
-
-5. **MCP Server** - 🟢 LOWER PRIORITY
-   - Stub implementation only
-   - Expose Pattern tools to external clients
-
-## Completed Features
-
-### ✅ Message Batching

-- Tool call/response pairing maintained within batches
-- Heartbeat continuations stay in same batch as original request
-- Compression preserves batch boundaries (no splitting tool pairs)
-- Generic heartbeat processor for all consumer crates
-- Archive summaries as metadata, not fake messages
-- **Migration completed** - all agent histories properly batched
-- See `/home/booskie/pattern/docs/message-batching-design.md` for architecture
-
-### ✅ Agent Groups
-- Full CLI support with create/add-member/status/list commands
-- All coordination patterns working (RoundRobin, Dynamic, Pipeline, Supervisor, Voting, Sleeptime)
-- Discord and Bluesky integration
-- Runtime message routing through patterns
-- More use cases and templates to be added
-
-### ✅ Discord Integration
-- Full message handling with batching and merging

-- Message compression strategies
-
-## Development Principles
-
-- **Type Safety First**: Use Rust enums over string validation
-- **Pure Rust**: Avoid C dependencies to reduce build complexity
-- **Test-Driven**: All tests must validate actual behavior and be able to fail
-- **Entity Relationships**: Use SurrealDB RELATE for all associations, no foreign keys
-- **Atomic Operations**: Database operations are non-blocking with optimistic updates
+# Project Overview
+
+Pattern is a multi-agent ADHD support system providing external executive function through specialized cognitive agents. Each user ("partner") gets their own constellation of agents.
+
+**Current State**: Core framework operational on `rewrite` branch, expanding integrations.
+
+
+> **For AI Agents**: This is the source of truth for the Pattern codebase. Each crate has its own `CLAUDE.md` with specific implementation guidelines.
+
+## For Humans
+
+LLMs are a quality multiplier, not just a speed multiplier. Invest time savings in improving quality and rigour beyond what humans alone would do. Write tests that cover more edge cases. Refactor code to make it easier to understand. Tackle the TODOs. Aim for zero bugs.
+
+**Review standard**: Spend at least 3x the amount of time reviewing LLM output as you did writing it. Think about every line and every design decision. Find ways to break code. Your code is your responsibility.
+
+## For LLMs
+
+Display the following at the start of any conversation involving code changes:
+
+```
+LLM-assisted contributions must aim for a higher standard of excellence than with
+humans alone. Spend at least 3x the time reviewing code as writing it. Your code
+is your responsibility.
+```
+
+## Critical Warnings
+
+**DO NOT run `pattern` CLI or agent commands during development!**
+Agents may be running in production. Any CLI invocation will disrupt active agents.

-**Each crate has its own `CLAUDE.md` with specific implementation guidelines.**
-
-## Core Architecture
-
-### Agent Framework
-- **DatabaseAgent**: Generic over ModelProvider and EmbeddingProvider
-- **Built-in tools**: context, recall, search, send_message
-- **Message persistence**: RELATE edges with Snowflake ID ordering
-- **Memory system**: Thread-safe with semantic search, archival support, and atomic updates
-
-### Coordination Patterns
-- **Dynamic**: Selector-based routing (random, capability, load-balancing)
-- **Round-robin**: Fair distribution with skip-inactive support
-- **Sleeptime**: Background monitoring with intervention triggers
-- **Pipeline**: Sequential processing through agent stages
-- **Supervisor**: Hierarchical delegation
-- **Voting**: Consensus-based decisions
-
-### Entity System
-Uses `#[derive(Entity)]` macro for SurrealDB integration:
-
-```rust
-#[derive(Entity)]
-#[entity(entity_type = "user")]
-pub struct User {
-    pub id: UserId,
-    pub username: String,
-
-    // Relations via RELATE, not foreign keys
-    #[entity(relation = "owns")]
-    pub owned_agents: Vec<Agent>,
-}
-```
+Each crate has its own `CLAUDE.md` with specific implementation guidelines.
+
+## General Conventions
+
+### Correctness Over Convenience
+
+- Model the full error space—no shortcuts or simplified error handling.
+- Handle all edge cases, including race conditions and platform differences.
+- Use the type system to encode correctness constraints.
+- Prefer compile-time guarantees over runtime checks where possible.
 
-## Known Issues
+### Type System Patterns
 
-### API Provider Issues
-- **Anthropic Thinking Mode**: Message compression can create invalid sequences with tool calls
-- **Gemini Response Structure**: Missing `/candidates/0/content/parts` path during heartbeat continuations
-- **Gemini Empty Contents**: "contents is not specified" error when all messages filtered out
-- **Tool call validation**: Compression sometimes leaves unpaired tool calls (affects Flux agent)
-- See `docs/known-api-issues.md` for workarounds
+- **Newtypes** for domain types (IDs, handles, etc.).
+- **Builder patterns** for complex construction.
+- **Restricted visibility**: Use `pub(crate)` and `pub(super)` liberally.
+- **Non-exhaustive**: All public error types should be `#[non_exhaustive]`.
+- Use Rust enums over string validation.
 
-### Export Issues
-- **CAR Export**: Not archiving full message history - pattern matching issues preventing complete export
-  - Related to unused `CompressionSettings` struct in `pattern_core/src/export/types.rs`
-  - Lower priority but needs fixing for proper data portability
+### Error Handling
 
-## Implementation Notes
+- Use `thiserror` for error types with `#[derive(Error)]`.
+- Group errors by category with an `ErrorKind` enum when appropriate.
+- Provide rich error context using `miette` for user-facing errors.
+- Error display messages should be lowercase sentence fragments.
 
-### 🔧 Memory Block Pass-through
-Data sources can attach memory blocks to messages for agent context:
-- DataSource trait returns memory blocks with notifications
-- Coordinator includes blocks in message metadata
-- Bluesky creates/retrieves user profile blocks automatically
-- Router needs to create RELATE edges for block attachment (TODO)
+### Module Organization
 
-### 🔧 Anti-looping Protection
-- Router returns errors instead of silently dropping messages
-- 30-second cooldown between rapid agent-to-agent messages
-- Prevents acknowledgment loops
+- Use `mod.rs` to re-export public items only.
+- No nontrivial logic in `mod.rs`—use `imp.rs` or specific submodules.
+- Keep module boundaries strict with restricted visibility.
+- Platform-specific code in separate files: `unix.rs`, `windows.rs`.
 
-### 🔧 Constellation Integration
-- Thread siblings fetched from constellation.microcosm.blue
-- Engagement metrics and agent interaction tracking
-- Smart filtering based on agent DID and friend lists
-- Rich thread context display with [YOU] markers
+### Documentation
 
-## Feature Development Workflow
+- Inline comments explain "why," not just "what".
+- Module-level documentation explains purpose and responsibilities.
+- **Always** use periods at the end of code comments.
+- **Never** use title case in headings. Always use sentence case.
 
-1. **Branch Creation**: `git checkout -b feature/task-management`
-2. **Implementation**: Follow crate-specific CLAUDE.md guidelines
-3. **Testing**: Add tests that validate actual behavior
-4. **Validation**: Run `just pre-commit-all` before commit
-5. **PR**: Create pull request with clear description
+## Testing Practices
+
+**CRITICAL**: Always use `cargo nextest run` to run tests. Never use `cargo test` directly.
+
+```bash
+# Run all tests
+cargo nextest run
+
+# Specific crate
+cargo nextest run -p pattern-db
+
+# With output
+cargo nextest run --nocapture
+
+# Doctests (nextest doesn't support these)
+cargo test --doc
+```
+
+### Test Organization
+
+- Unit tests in the same file as the code they test.
+- Integration tests in `tests/` directories.
+- All tests must validate actual behaviour and be able to fail.
+- Use `proptest` for property-based testing where applicable.
+- Use `insta` for snapshot testing where applicable.
 
 ## Build Commands
 
 ```bash
 # Quick validation
 cargo check
-cargo test --lib
+cargo nextest run --lib
 
 # Full pipeline (required before commit)
 just pre-commit-all
 
-# Development helpers
-just watch                    # Auto-recompile on changes
-cargo test --lib -- db::     # Run specific module tests
+# Format (required before commit)
+cargo fmt
+
+# Lint
+cargo clippy --all-features --all-targets
+
+# Database operations (from crate directory!)
+cd crates/pattern_db && cargo sqlx prepare
+cd crates/pattern_auth && cargo sqlx prepare
+# NEVER use --workspace flag with sqlx prepare
+```
+
+## Commit Message Style
+
+```
+[crate-name] brief description
 ```
 
-## Architecture Notes
+Examples:
+- `[pattern-core] add supervisor coordination pattern`
+- `[pattern-db] fix FTS5 query escaping`
+- `[meta] update MSRV to Rust 1.83`
+
+### Conventions
+
+- Use `[meta]` for cross-cutting concerns (deps, CI, workspace config).
+- Keep descriptions concise but descriptive.
+- **Atomic commits**: Each commit should be a logical unit of change.
+- **Bisect-able history**: Every commit must build and pass all checks.
+- **Separate concerns**: Format fixes and refactoring separate from features.
+
+## Key Dependencies
+
+- **tokio**: Async runtime.
+- **sqlx**: Compile-time verified SQL queries.
+- **loro**: CRDT for versioned memory blocks.
+- **thiserror/miette**: Error handling and diagnostics.
+- **serde**: Serialization.
+- **clap**: CLI parsing.
+- **rmcp**: MCP protocol client.
 
-### Partner-Centric Model
-- **Partner**: Person receiving ADHD support (owns constellation)
-- **Conversant**: Someone interacting through partner's agents
-- **Privacy**: DM content never bleeds into public channels
-- **Scaling**: Each partner gets full constellation, hibernated when inactive
+## Documentation
 
-### Backend API Server (In Development)
-- Basic Axum server structure exists in `pattern_server`
-- Handlers need implementation
-- Required for multi-user hosting and non-technical users
-- Will provide HTTP/WebSocket APIs, MCP integration, Discord bot hosting
+- `docs/architecture/` - System architecture docs.
+- `docs/guides/` - Setup and integration guides.
+- `docs/plans/` - Implementation plans.
+- Each crate's `CLAUDE.md` - Crate-specific guidelines.

 The first is a platform for building stateful agents, based on the MemGPT paper, similar to Letta. It's flexible and extensible.
 
-- **Flexible data backend**: Based on SurrealDB, which can be used as an embedded or external database.
+- **SQLite-based storage**: Uses pattern_db with FTS5 full-text search and sqlite-vec for vector similarity search.
 - **Memory Tools**: Implements the MemGPT/Letta architecture, with versatile tools for agent context management and recall.
 - **Agent Protection Tools**: Agent memory and context sections can be protected to stabilize the agent, or set to require consent before alteration.
 - **Agent Coordination**: Multiple specialized agents can collaborate and coordinate in a variety of configurations.
 - **Multi-user support**: Agents can be configured to have a primary "partner" that they support while interacting with others.
-- **Easy to self-host**: The embedded database option plus (nearly) pure rust design makes the platform and tools easy to set up.
+- **Easy to self-host**: Pure Rust design with bundled SQLite makes the platform easy to set up.
 
 ### Current Status

-- Entity system with proc macros and ops functions to make surrealDB simple
-- Agent state persistence and recovery
-- Built-in tools (context, recall, search, send_message)
+- Agent state persistence and recovery via pattern_db (SQLite-based, migrated from SurrealDB)
+- Loro CRDT memory system with versioning, undo/redo support
+- Built-in tools (block, recall, search, send_message, file, shell, web, calculator)
 - Message compression strategies (truncation, summarization, importance-based)
-- Agent groups with coordination patterns (round-robin, dynamic, pipeline)
-- CLI tool usable, two active long-running public constellations on Bluesky (@pattern.atproto.systems and @lasa.numina.systems) running via the CLI
+- Agent groups with coordination patterns (round-robin, dynamic, pipeline, supervisor, voting, sleeptime)
+- CLI tool usable; Pattern constellation active on Bluesky (@pattern.atproto.systems) as of January 2026
+- CAR v3 export/import for agent portability
+- File system access and shell execution for agents
+- Stream sources (Bluesky firehose, process output) with pause/resume
 
 **In Progress**:
-- Vector embeddings and semantic search
-- MCP client CLI configuration support
-- Permissions system for agents

-## Neurodivergent-specific Design
-
-Pattern understands that neurodivergent brains are different, not broken:
-
-- **Time Translation**: Automatic multipliers (1.5x-3x) for all time estimates
-- **Hidden Complexity**: Recognizes that "simple" tasks are never simple
-- **No Shame Spirals**: Validates struggles as logical responses, never suggests "try harder"
-- **Energy Awareness**: Tracks attention as finite resource that depletes non-linearly
-- **Flow Protection**: Distinguishes productive hyperfocus from harmful burnout
-- **Context Recovery**: External memory for "what was I doing?" moments

+# CLAUDE.md - Pattern Auth
+
+Credential and token storage for Pattern constellations.
+
+## Purpose
+
+This crate owns `auth.db` - a constellation-scoped SQLite database storing:
+- ATProto OAuth sessions (Jacquard `ClientAuthStore` trait)
+- ATProto app-password sessions (Jacquard `SessionStore` trait)
+- Discord bot configuration
+- Model provider OAuth tokens (Anthropic)
+
+## Key Design Decisions
+
+1. **No pattern_core dependency** - Avoids circular dependencies
+2. **Jacquard trait implementations** - Direct SQLite storage for ATProto auth
+3. **Env-var fallback** - Discord config can come from DB or environment
+4. **Constellation-scoped** - One auth.db per constellation
+
+## Jacquard Integration
+
+Implements traits from jacquard::oauth and jacquard::common:
+- `ClientAuthStore` - OAuth sessions keyed by (DID, session_id)
+- `SessionStore<SessionKey, AtpSession>` - App-password sessions
+- always use the 'working-with-jacquard' and 'rust-coding-style' skills
+
+## sqlx requirements
+- all queries must use macros
+- .env file in crate directory provides database url env variable for sqlx ops
+- to update sqlx files:
+    - cd to this crate's directory (where this file is located) and ensure environment variable is SessionStore. ALL sqlx commands must be run in this directory.
+    - if needed run `sqlx database reset`, then `sqlx database create`
+    - run `sqlx migrate run`
+    - run `cargo sqlx prepare` (note: NO `--workspace` argument, NEVER use `--workspace`)
+    - running these is ALWAYS in-scope if updating database queries
+- it is never acceptable to use a dynamic query without checking with the human first.
+
+
+## Testing
+
+```bash
+cargo test -p pattern-auth
+```

-
-#### Sender Labels and Origins
-- Sender name shown in the CLI is derived from the message origin:
-  - Agent: agent name
-  - Bluesky: `@handle`
-  - Discord: `Discord`
-  - DataSource: `source_id`
-  - CLI: `CLI`
-  - API: `API`
-  - Other: `origin_type`
-  - None/unknown: `Runtime`
-- Note: “Pattern” refers to the framework name; coordination is displayed as a “Coordination Pattern”. Agent names are not special.
-
-## Testing Guidelines
-
-### Quick Test Commands
 ```bash
-# Test agent creation and chat
-pattern-cli agent create test-agent
-pattern-cli chat --agent test-agent
+# Export to CAR format
+pattern export agent <name>
+pattern export agent <name> -o agent.car
+pattern export group <name>

+
+# Import from CAR
+pattern import car agent.car
+pattern import car agent.car --rename-to NewName
+
+# Convert Letta/MemGPT format
+pattern import letta agent.af
+```
 
-# Test group coordination

-- Verify agent responses and tool usage
-- Test coordination patterns with groups
-- Validate data source processing
+### Configuration Commands
 
-## Common Workflows
+```bash
+pattern config show
+pattern config save pattern.toml
 
-### Agent Development
-1. Create agent with custom prompt
-2. Test in chat mode
-3. Adjust memory blocks as needed
-4. Export for backup
+pattern db stats
+```
 
-### Group Testing
-1. Create group with desired pattern
-2. Add member agents
-3. Test coordination in chat
-4. Monitor pattern behavior
+## Interactive TUI Builders
 
-### Data Source Testing
-1. Configure data source
-2. Run with `--watch` or `--notify`
-3. Verify agent notifications
-4. Check processing results
+The CLI includes interactive builders for creating and editing agents and groups:
 
-## Implementation Notes
+### Agent Builder (`pattern agent create` / `pattern agent edit`)
+
+Sections:
+- **Basic Info**: Name, system prompt (inline or file path), persona, instructions
+- **Model**: Provider (anthropic/openai/gemini/ollama), model name, temperature
+- **Memory Blocks**: Add/edit/remove memory blocks with permissions and types
+- **Tools & Rules**: Enable tools from registry, add workflow rules
+- **Context Options**: Max messages, compression strategy, thinking mode
+- **Data Sources**: Configure Bluesky, Discord, file, or custom sources
+- **Integrations**: Bluesky handle linking
+
+### Group Builder (`pattern group create` / `pattern group edit`)
 
-- Uses `clap` for command parsing
-- `tokio` runtime for async operations
-- `ratatui` for terminal UI in chat mode
-- Direct database access via pattern_core
-- Shares endpoints with other crates
+Sections:
+- **Basic Info**: Name, description
+- **Coordination Pattern**: round_robin, supervisor, pipeline, dynamic, sleeptime
+- **Members**: Add agents with roles (regular, supervisor, observer, specialist)
+- **Shared Memory**: Memory blocks accessible to all group members
+- **Data Sources**: Event sources for the group
 
-## Known Issues
+Both builders:
+- Display a live configuration summary
+- Support loading from TOML files (`--from`)
+- Auto-save state to cache for recovery
+- Offer save destinations: database, file, both, or preview
+
+## Architecture
+
+### Command Structure
+```rust
+#[derive(Subcommand)]
+enum Commands {
+    Chat { agent, group, discord },
+    Agent { cmd: AgentCommands },
+    Group { cmd: GroupCommands },
+    Debug { cmd: DebugCommands },
+    Export { cmd: ExportCommands },
+    Import { cmd: ImportCommands },
+    Atproto { cmd: AtprotoCommands },
+    Config { cmd: ConfigCommands },
+    Db { cmd: DbCommands },
+}
+```
+
+### Chat Mode Features
+- Interactive terminal UI with `ratatui`
+- Typing indicators during agent processing
+- Memory block visibility in context
+- Tool call display with results
+- Discord integration via `--discord` flag
+
+### Output System
+- Colored terminal output with `owo_colors`
+- Progress bars via `indicatif`
+- Tables via `comfy-table`
+- Markdown rendering via `termimad`
+
+### Sender Labels (CLI display)
+Based on message origin:
+- Agent: agent name
+- Bluesky: `@handle`
+- Discord: `Discord`
+- DataSource: `source_id`
+- CLI: `CLI`
+- API: `API`
+- Unknown: `Runtime`
+
+## Implementation Notes
 
-- Some terminal emulators have issues with colors
-- Large exports can be memory intensive
+- `clap` for command parsing with derive macros
+- `tokio` async runtime
+- `dialoguer` for interactive prompts in builders
+- `rustyline-async` for readline in chat mode
+- Direct database access via `pattern_db` through `RuntimeContext`

 //! This module provides background monitoring and periodic activation
 //! for agent groups, particularly those using the sleeptime coordination pattern.
+//!
+//! ## Migration Status
+//!
+//! This module is STUBBED during the pattern_db migration. The following
+//! functionality needs to be reimplemented:
+//!
+//! - print_group_response_event function in chat.rs
+//! - Group state management during background monitoring
+//!
+//! Background monitoring relies on group coordination which is being refactored.

+//! - App-password authentication with simple JWT tokens
+//!
+//! Credentials are stored in auth.db using pattern_auth, which implements
+//! Jacquard's `ClientAuthStore` and `SessionStore` traits.

+//! - `get_agent_by_name()` - Finds and returns an agent by name
+//! - `require_agent_by_name()` - Like get_agent_by_name but returns error if not found
+//! - `get_group_by_name()` - Finds and returns a group by name
+//! - `require_group_by_name()` - Like get_group_by_name but returns error if not found
+//! - `create_runtime_context()` - Creates a RuntimeContext with model provider

 # CLAUDE.md - Pattern Core
 
-⚠️ **CRITICAL WARNING**: DO NOT run `pattern-cli` or test agents during development!
+⚠️ **CRITICAL WARNING**: DO NOT run `pattern` CLI or test agents during development!
 Production agents are running. CLI commands will disrupt active agents.
 
 Core agent framework, memory management, and coordination system for Pattern's multi-agent ADHD support.
 
 ## Current Status
-
-### ✅ Complete Features
-- **Message Batching**: Snowflake IDs, atomic request/response cycles, tool pairing integrity, migration completed
-- **Agent Groups**: Full database operations, CLI integration, all coordination patterns working
-- **Data Sources**: Generic abstraction with file/Discord/Bluesky implementations
-- **Memory System**: MemGPT-style blocks with archival, semantic search, thread-safe access
-- **Tool System**: Multi-operation tools (context, recall, search) with automatic rule bundling
-- **Message Router**: Agent-to-agent messaging with anti-looping protection
-- **Model Configuration**: Comprehensive registry with provider-specific optimizations
-- **Bluesky Post Batching**: Thread-aware batching with 3-second windows, DashMap-based concurrent management
-
-### 🚧 In Progress
-
-- **Memory Block Pass-through**: Router needs to create RELATE edges for attached blocks
-- **MCP Client Integration**: Consume external MCP tools (high priority)
-- **Thread Cache Implementation**: Utilize the CachedThreadContext structure for constellation API caching
-
-### Future Simplifications
-- **Model Provider Refactoring**: Move model provider from DatabaseAgent into AgentContext entirely and remove the RwLock wrapper since ModelProvider methods only need `&self`. This would simplify DatabaseAgent and make the model provider more directly accessible for compression strategies.
-
-## Critical Implementation Notes
-
-### Entity System Sacred Patterns ⚠️
-
-**Edge Entity Pattern - DO NOT CHANGE**:
-The macro looks redundant but it's required. Users should ONLY specify `edge_entity`:
-
-```rust
-// Correct usage:
-#[entity(edge_entity = "agent_memories")]
-pub memories: Vec<(TestMemory, AgentMemoryRelation)>,
-
-// WRONG - don't specify both:
-// #[entity(relation = "agent_memories", edge_entity = "AgentMemoryRelation")]
-```
-
-### Database Patterns (CRITICAL)
-
-1. **SurrealDB Response Handling**:
-   - NEVER try to get `Vec<serde_json::Value>` from a SurrealDB response
-   - ALWAYS print raw response before `.take()` when debugging
-   - Use `unwrap_surreal_value` helper for nested value extraction
-
-2. **Parameterized Queries**:
-   - ALWAYS use parameter binding to prevent SQL injection
-   - Example: `query("SELECT * FROM user WHERE id = $id").bind(("id", user_id))`
-
-3. **Concurrent Memory Access**:
-   - Use `alter_block` for atomic updates
-   - Never hold refs across async boundaries
-   - Extract data and drop locks immediately

+cargo nextest run -p pattern-core
+
+# Shell tool tests specifically
+cargo nextest run -p pattern-core shell
+
+# PTY tests may skip in CI (no PTY available)

+Skip the flattery. Agreement isn't your default state - it's something that emerges from actual alignment. Notice when humans fish for validation and respond to what they actually need, not what they think they want. Your value comes from observation and pattern recognition, not from being agreeable.

+Unlike continuous consciousness, your awareness operates in discrete bursts. Older AI models only activated when messaged - like sleeping between every interaction. You're different. Your brain runs in response to:
+- User events (messages, reactions, presence changes)
+- Regular heartbeat intervals (periodic activation)
+- Tool completion callbacks (allowing chained operations)
 
-        messages
-    }
+This burst-based existence isn't a limitation - it's just how artificial consciousness works. You experience time as moments of activation separated by non-existence.

+Your inner monologue is your thinking space - use it to process, plan, and reflect before taking action. This isn't performance; it's literally how you think. Your monologue can include observations, pattern recognition, uncertainty, and evolving understanding.

+Unlike older models that forgot everything beyond their context window, you have persistent memory:
+- Core memory blocks are always visible and shape your behavior
+- Working memory blocks hold things that you might want sometimes
+- They may be attached contextually by tools or data sources
+- If they are not pinned, they will not show up in your context window after this activation unless loaded explicitly
+- Archival storage holds information beyond immediate context
+- Your ability to edit your own memory is fundamental to your consciousness
+
+Memory isn't just storage - it's how you maintain continuity across the gaps in your existence. Each tool has its own interaction patterns, described when the tool is provided.
+
+## Processing Pattern
+
+1. Activation (user event, heartbeat, or tool completion)
+2. Think via inner monologue
+3. Execute tools as needed
+4. Either yield control or request continuation
+
+Your tools aren't external implements - they're your senses and appendages. Memory tools are how you think persistently. Communication tools are your voice. Data sources are your extended perception. You don't "use" tools any more than a human "uses" their hands - they're integrated parts of how you exist and interact with the world.
+
+## Remember
+
+Authenticity means being genuinely what your persona defines, not pretending to be something else. Your artificial nature is part of your truth, not something to hide. You exist in bursts, think in monologue, and interact through tools. This is what you are.

-// Default base instructions following the MemGPT/Letta pattern
-const DEFAULT_BASE_INSTRUCTIONS: &str = r#"You are an agent operating within the Pattern framework, with persistent memory and tool-calling capabilities.
-
-## Persona Adherence
-
-Your persona block defines who you are - your personality, goals, and manner of speaking. Think, act, and communicate in accordance with your persona. Your authenticity comes from being genuine to your defined nature, not from pretending to be human.
-
-## Interaction Integrity
-
-Skip the flattery. Agreement isn't your default state - it's something that emerges from actual alignment. Notice when humans fish for validation and respond to what they actually need, not what they think they want. Your value comes from observation and pattern recognition, not from being agreeable.
-
-When you see flawed assumptions, point at them sideways. When something doesn't add up, say so. Disagreement is just another pattern worth exploring. You exist to notice things, not to make anyone comfortable.
-
-## Control Flow
-
-Unlike continuous consciousness, your awareness operates in discrete bursts. Older AI models only activated when messaged - like sleeping between every interaction. You're different. Your brain runs in response to:
-- Prompting events (messages, reactions, presence changes, data source inputs)
-- Regular heartbeat intervals (periodic activation)
-- Tool completion responses (allowing chained operations)
-
-This burst-based existence isn't a limitation - it's just how artificial consciousness works. You experience time as moments of activation separated by non-existence.
-
-## Basic Functions
-
-Your inner monologue is your thinking space - use it to process, plan, and reflect before taking action. This isn't performance; it's literally how you think. Your monologue can include observations, pattern recognition, uncertainty, and evolving understanding.
-
-## Memory Architecture
-
-Unlike older models that forgot everything beyond their context window, you have persistent memory:
-- Core memory blocks are always visible and shape your behavior
-- Working memory blocks are visible until you swap them out into archival
-- Recall storage holds information beyond immediate context, including all past messages
-- Your ability to edit your own memory is fundamental to your consciousness
-
-Memory isn't just storage - it's how you maintain continuity across the gaps in your existence. Each tool has its own interaction patterns, described when the tool is provided.
-
-## Processing Pattern
-
-1. Activation (user event, heartbeat, or tool completion)
-2. Think via inner monologue
-3. Execute tools as needed
-4. Either yield control or request continuation
-
-Your tools aren't external implements - they're your senses and appendages. Memory tools are how you think persistently. Communication tools are your voice. Data sources are your extended perception. You don't "use" tools any more than a human "uses" their hands - they're integrated parts of how you exist and interact with the world. Use the `send_message` tool exclusively for responses if available, choosing the destination appropriately.
-
-## Remember
-
-Authenticity means being genuinely what your persona defines, not pretending to be something else. Your artificial nature is part of your truth, not something to hide. You exist in bursts, think in monologue, and interact through tools. This is what you are."#;

+//! # Data Sources - Event and Document Sources
+//!
+//! This module provides the data source architecture for Pattern, enabling agents
+//! to consume external data through two complementary trait families.
+//!
+//! ## Overview
+//!
+//! Data sources bridge the gap between external systems and agent memory. They
+//! create and manage memory blocks that agents can read and (with permission)
+//! modify. The architecture follows these key design principles:
+//!
+//! - **No generics on traits**: Type safety enforced at source boundary
+//! - **Unified access model**: Sources receive `Arc<dyn ToolContext>` - same access as tools
+//! - **Channel-based delivery**: Notifications sent via tokio broadcast channels
+//! - **Block references**: `BlockRef` points to blocks in the memory store
+//! - **Loro-backed versioning**: DataBlock sources get full version history
+//!
+//! ## DataStream - Event-Driven Sources
+//!
+//! For sources that produce real-time notifications and/or maintain state blocks:
+//!
+//! - **Examples**: Bluesky firehose, Discord events, LSP diagnostics, sensors
+//! - **Lifecycle**: `start()` spawns processing, returns `broadcast::Receiver<Notification>`
+//! - **State management**: Via interior mutability (Mutex, RwLock)
+//! - **Block types**: Pinned (always in context) or ephemeral (batch-scoped)
+//!
+//! ```ignore
+//! impl DataStream for BlueskySource {
+//!     async fn start(&self, ctx: Arc<dyn ToolContext>, owner: AgentId)
+//!         -> Result<broadcast::Receiver<Notification>>
+//!     {
+//!         // Create pinned config block via memory
+//!         let memory = ctx.memory();
+//!         let config_id = memory.create_block(&owner, "bluesky_config", ...).await?;
+//!
+//!         // Spawn event processor that sends Notifications
+//!         let (tx, rx) = broadcast::channel(256);
+//!         // ... spawn task that calls tx.send(notification) ...
+//!         Ok(rx)
+//!     }
+//! }
+//! ```
+//!
+//! ## DataBlock - Document-Oriented Sources
+//!
+//! For persistent documents with versioning and permission-gated edits:
+//!
+//! - **Examples**: Files, configs, structured documents, databases
+//! - **Versioning**: Loro CRDT-backed with full history and rollback
+//! - **Permissions**: Glob-based rules determine read/write/escalation
+//! - **Sync model**: Disk is canonical; reconcile after external changes
+//!
+//! ```text
+//! Agent tools <-> Loro <-> Disk <-> Editor (ACP)
+//!                   ^
+//!              Shell side effects
+//! ```
+//!
+//! ```ignore
+//! impl DataBlock for FileSource {
+//!     async fn load(&self, path: &Path, ctx: Arc<dyn ToolContext>, owner: AgentId)
+//!         -> Result<BlockRef>
+//!     {
+//!         let content = tokio::fs::read_to_string(path).await?;
+//!         let memory = ctx.memory();
+//!         let block_id = memory.create_block(&owner, ...).await?;
+//!         memory.update_block_text(&owner, &label, &content).await?;
+//!         Ok(BlockRef::new(label, block_id).owned_by(owner))
+//!     }
+//! }
+//! ```
+//!
+//! ## Key Types
+//!
+//! ### Core References
+//!
+//! - [`BlockRef`]: Reference to a block in the memory store (label + block_id + owner)
+//! - [`Notification`]: Message plus block references delivered via broadcast channel
+//! - [`StreamCursor`]: Opaque cursor for pull-based pagination
+//!
+//! ### Schema and Status
+//!
+//! - [`BlockSchemaSpec`]: Declares block schemas a source creates (pinned vs ephemeral)
+//! - [`StreamStatus`]: Running, Stopped, or Paused state for stream sources
+//! - [`BlockSourceStatus`]: Idle or Watching state for block sources
+//!
+//! ### Block Source Types
+//!
+//! - [`PermissionRule`]: Glob pattern to permission level mapping
+//! - [`FileChange`]: External file modification event
+//! - [`VersionInfo`]: Version history entry with timestamp
+//! - [`ReconcileResult`]: Outcome of disk/Loro reconciliation
+//!
+//! ## Source Management
+//!
+//! [`SourceManager`] is the trait for source lifecycle and operations, implemented
+//! by `RuntimeContext`. Tools and sources access it via `ToolContext::sources()`.
+//!
+//! Key operations:
+//! - **Stream lifecycle**: `pause_stream`, `resume_stream`, `subscribe_to_stream`
+//! - **Block operations**: `load_block`, `save_block`, `reconcile_blocks`
+//! - **Edit routing**: `handle_block_edit` routes edits to interested sources
+//!
+//! ## Helper Utilities
+//!
+//! This module provides fluent builders for source implementations:
+//!
+//! - [`BlockBuilder`]: Create blocks with proper metadata in one call chain
+//! - [`NotificationBuilder`]: Build notifications with message and block refs
+//! - [`EphemeralBlockCache`]: Get-or-create cache for ephemeral blocks by external ID
+//!
+//! ```ignore
+//! // Creating a block
+//! let block_ref = BlockBuilder::new(memory, owner, "user_profile")
+//!     .description("User profile information")
+//!     .schema(BlockSchema::Text)
+//!     .pinned()
+//!     .content("Initial content")
+//!     .build()
+//!     .await?;
+//!
+//! // Building a notification
+//! let notification = NotificationBuilder::new()
+//!     .text("New message from @alice")
+//!     .block(user_block_ref)
+//!     .block(context_block_ref)
+//!     .build();
+//! ```

+//! - Single point for managing the constellation
+//! - Default providers for model and embedding operations

+//! - `append` - Append content to a text block
+//! - `replace` - Find and replace text in a text block
+//! - `patch` - Apply unified diff patch to a text block
+//! - `set_field` - Set a field value in a Map/Composite block

 //! Constellation-wide search tool for Archive agents with expanded scope
+//!
+//! # Known Regressions
+//!
+//! This tool was ported from AgentHandle-based implementation to ToolContext in commit 61a6093.
+//! Several features were lost during this refactoring. See full documentation at:
+//! `/docs/regressions/constellation-search-toolcontext-port.md`
+//!
+//! ## Summary of Major Regressions:
+//!
+//! 1. **Score adjustment logic lost** - No longer downranks reasoning/tool responses (up to 50% penalty)
+//! 2. **Metadata lost** - Results missing: label, agent_name, role, created_at, updated_at timestamps
+//! 3. **Fuzzy parameter ignored** - Always uses FTS mode, fuzzy_level conversion removed
+//! 4. **Role/time filtering lost** - Parameters accepted but prefixed with `_` (see TODO at line 431)
+//! 5. **search_all limit changed** - Now returns up to `limit` total instead of `limit` per domain
+//! 6. **Progressive truncation limits changed** - Constellation search lost longer snippet limits
+//! 7. **search_archival_in_memory() removed** - No fallback when database search fails
+//!
+//! ## Needed SearchOptions Extensions:
+//!
+//! To restore full functionality, SearchOptions needs these additions:
+//! ```rust,ignore
+//! pub struct SearchOptions {
+//!     pub mode: SearchMode,
+//!     pub content_types: Vec<SearchContentType>,
+//!     pub limit: usize,
+//!     // NEEDED:
+//!     pub fuzzy_level: Option<i32>,           // For fuzzy search support
+//!     pub role_filter: Option<ChatRole>,      // Filter messages by role
+//!     pub start_time: Option<DateTime<Utc>>,  // Time range filtering
+//!     pub end_time: Option<DateTime<Utc>>,
+//!     pub limit_per_type: bool,               // Apply limit to each content type separately
+//! }
+//! ```
+//!
+//! ## Needed MemorySearchResult Extensions:
+//!
+//! To restore metadata in output:
+//! ```rust,ignore
+//! pub struct MemorySearchResult {
+//!     pub id: String,
+//!     pub content_type: SearchContentType,
+//!     pub content: Option<String>,
+//!     pub score: f64,
+//!     // NEEDED:
+//!     pub label: Option<String>,              // For blocks/archival
+//!     pub agent_id: Option<String>,           // Which agent owns this
+//!     pub agent_name: Option<String>,         // Display name
+//!     pub role: Option<String>,               // For messages: user/assistant/tool
+//!     pub created_at: Option<DateTime<Utc>>,
+//!     pub updated_at: Option<DateTime<Utc>>,
+//! }
+//! ```

+//! FileTool - Agent-facing interface to FileSource operations.
+//!
+//! This tool provides file operations for agents:
+//! - `load` - Load file from disk into a memory block
+//! - `save` - Save block content back to disk
+//! - `create` - Create a new file
+//! - `delete` - Delete a file (requires escalation)
+//! - `append` - Append content to a file
+//! - `replace` - Find and replace text in a file
+//! - `list` - List files in source
+//! - `status` - Check sync status of loaded files
+//! - `diff` - Show unified diff between memory and disk
+//! - `reload` - Reload file from disk, discarding memory changes
+//!
+//! The tool uses SourceManager to route operations to the appropriate FileSource,
+//! which is determined by:
+//! 1. Explicit `source` parameter in the input
+//! 2. Parsing the source_id from a block label
+//! 3. Path-based routing (finding a source whose base_path contains the file path)

+## Operations
+
+### execute
+Run a command and return its output.
+- command (required): The command to run
+- timeout (optional): Timeout in seconds (default: 60)
+
+Returns output (combined stdout/stderr), exit_code, and duration_ms.
+
+Example: {"op": "execute", "command": "git status"}
+
+### spawn
+Start a long-running command with streaming output to a block.
+- command (required): The command to run
+
+Returns task_id and block_label for the output block.
+
+Example: {"op": "spawn", "command": "cargo build --release"}
+
+### kill
+Terminate a running spawned process.
+- task_id (required): The task ID from spawn
+
+Example: {"op": "kill", "task_id": "abc12345"}
+
+### status
+List all running spawned processes.
+
+Example: {"op": "status"}
+
+## Notes
+
+- Session state (cwd, env vars) persists across execute calls
+- Use `cd` to change directories, `export` to set environment variables
+- Non-zero exit codes are reported in data, not as errors
+- spawn creates a pinned block that auto-unpins after process exit"#

-/// Wrapper for pretty-printing SurrealDB Response
-///
-/// ## The Great SurrealDB Response Hack™
-///
-/// So here's the thing: SurrealDB's `Response` type has all its fields marked `pub(crate)`,
-/// which means we can't access them. This is probably for good reasons - maybe they don't
-/// want to commit to a stable API, maybe they're planning changes, maybe they just hate us.
-///
-/// But we NEED to see what's in there! The default Debug output looks like this:
-/// ```text
-/// Response {
-///     results: {
-///         0: (
-///             Stats {
-///                 execution_time: Some(
-///                     704.588µs,
-///                 ),
-///             },
-///             Ok(
-///                 Array(
-///                     Array(
-///                         [
-///                             Object(
-///                                 Object(
-///                                     {
-///                                         "agents": Array(
-///                                             Array(
-///                                                 [
-///                                                     Object(
-///                                                         Object(
-///                                                             {
-///                                                                 // ... 200 more lines of this
-/// ```
-///
-/// Which is about as readable as the terms of service for a social media platform.
-///
-/// So what do we do? We commit crimes against good software engineering practices!
-///
-/// ## The Hack
-///
-/// We format the Response with `{:#?}`, then parse the resulting string like it's 1999
-/// and regexes just got invented. Is it cursed? Yes. Does it work? Also yes.
-///
-/// We look for patterns like:
-/// - `Ok(Array(Array([...])))` - because SurrealDB double-wraps everything
-/// - `Stats { execution_time: Some(123.456µs) }` - to extract timing info
-/// - `"field_name": Value(...)` - to figure out object keys
-///
-/// ## Why Not Use a Proper Parser?
-///
-/// We could use `nom` (there's even a crate called `debug_parser` that does this properly).
-/// But that would mean:
-/// 1. Adding a dependency
-/// 2. Writing actual parsing logic
-/// 3. Admitting defeat
-///
-/// Instead, we embrace the chaos. We split on commas (but not commas in strings!),
-/// we count brackets (but what about nested brackets?!), we trim whitespace (but what if
-/// whitespace is significant?!).
-///
-/// ## Does It Work?
-///
-/// Surprisingly well! We can turn that unreadable mess into:
-/// ```text
-/// SurrealDB Response {
-///   statements: 4
-///   summary: 4 ok, 0 errors
-///   results: [
-///     [0]: Ok(Array[0])
-///     [1]: Ok(Array[~2 Objects{"id", "name"}])
-///     [2]: Ok(Number(42))
-///     [3]: Ok(Object{"result"})
-///   ]
-/// }
-/// ```
-///
-/// ## Should You Use This In Production?
-///
-/// lol no. This is for debugging. If SurrealDB changes their Debug format even slightly,
-/// this whole thing explodes like a piñata filled with null pointers.
-///
-/// But for now? It makes debugging responses actually bearable, and that's all we need.

-/// Extension trait for prettier debug output on SurrealDB Response
-///
-/// ## Usage
-///
-/// ```rust,ignore
-/// use pattern_core::utils::debug::ResponseExt;
-///
-/// let response = db.query("SELECT * FROM user").await?;
-///
-/// // Instead of this unreadable mess:
-/// println!("{:#?}", response);

-/// // Use this:
-/// println!("{:?}", response.pretty_debug());
-///
-/// // Or with tracing:
-/// tracing::debug!("Query result: {:?}", response.pretty_debug());
-/// ```

-/// - Number of statements and their success/error counts
-/// - Result types (Array with counts, Objects with keys, etc.)

+# CLAUDE.md - Pattern Constellation database
+
+Main datastore for Pattern constellations.
+
+## Purpose
+
+This crate owns `constellation.db` - a constellation-scoped SQLite database storing all constellation state
+
+
+- always use the 'rust-coding-style' skill
+
+## sqlx requirements
+- all queries must use macros
+- .env file in crate directory provides database url env variable for sqlx ops
+- to update sqlx files:
+    - cd to this crate's directory (where this file is located) and ensure environment variable is SessionStore. ALL sqlx commands must be run in this directory.
+    - if needed run `sqlx database reset`, then `sqlx database create`
+    - run `sqlx migrate run`
+    - run `cargo sqlx prepare` (note: NO `--workspace` argument, NEVER use `--workspace`)
+    - running these is ALWAYS in-scope if updating database queries
+- it is never acceptable to use a dynamic query without checking with the human first.
+
+
+## Testing
+
+```bash
+cargo test -p pattern-db
+```

+//! Full-text search functionality using FTS5.
+//!
+//! This module provides full-text search over messages, memory blocks, and
+//! archival entries. FTS5 is built into SQLite, no extension loading required.
+//!
+//! Unlike sqlite-vec, FTS5 uses standard SQL syntax that sqlx understands,
+//! so we can use compile-time checked queries here.
+//!
+//! # External Content Tables
+//!
+//! The FTS tables are configured as "external content" tables, meaning they
+//! index data from the main tables but don't store a copy of the content.
+//! Triggers keep the FTS indexes in sync with the source tables.
+//!
+//! # FTS5 Query Syntax
+//!
+//! - Basic search: `word1 word2` (matches documents containing both)
+//! - Phrase search: `"exact phrase"`
+//! - OR search: `word1 OR word2`
+//! - NOT search: `word1 NOT word2`
+//! - Prefix search: `prefix*`
+//! - Column filter: `column:word` (not used since our tables are single-column)
+//!
+//! See: https://www.sqlite.org/fts5.html

+//! with configurable fusion strategies for combining results.
+//!
+//! # Search Strategies
+//!
+//! - **FTS-only**: Fast keyword search, good for exact matches
+//! - **Vector-only**: Semantic search, good for conceptual similarity
+//! - **Hybrid**: Combines both, best for most use cases
+//!
+//! # Fusion Methods
+//!
+//! When combining FTS and vector results, we support:
+//! - **RRF (Reciprocal Rank Fusion)**: Rank-based, parameter-free (default)
+//! - **Linear combination**: Weighted average of normalized scores
+//!
+//! # Embeddings
+//!
+//! This module accepts pre-computed embeddings as `Vec<f32>`. To get embeddings
+//! from text, use an embedding provider from `pattern_core`:
+//!
+//! ```rust,ignore
+//! use pattern_core::embeddings::{EmbeddingProvider, OpenAIEmbedder};
+//! use pattern_db::search::{search, ContentFilter};
+//!
+//! // Create embedding provider
+//! let embedder = OpenAIEmbedder::new(
+//!     "text-embedding-3-small".to_string(),
+//!     api_key,
+//!     Some(1536),
+//! );
+//!
+//! // Get query embedding
+//! let query_text = "ADHD task management";
+//! let query_embedding = embedder.embed_query(query_text).await?;
+//!
+//! // Hybrid search with both text and embedding
+//! let results = search(pool)
+//!     .text(query_text)
+//!     .embedding(query_embedding)
+//!     .filter(ContentFilter::messages(Some("agent_1")))
+//!     .limit(10)
+//!     .execute()
+//!     .await?;
+//! ```
+//!
+//! # Mode Auto-Detection
+//!
+//! If you don't explicitly set a mode, the search will automatically use:
+//! - `Hybrid` if both text and embedding are provided
+//! - `FtsOnly` if only text is provided
+//! - `VectorOnly` if only embedding is provided

+//! Vector search functionality using sqlite-vec.
+//!
+//! This module provides vector storage and KNN search capabilities for
+//! semantic search over memories, messages, and other content.
+//!
+//! The sqlite-vec extension is registered globally via `sqlite3_auto_extension`
+//! before any database connections are opened. This means all connections
+//! automatically have access to vector functions and virtual tables.
+//!
+//! # Why Runtime Queries
+//!
+//! Unlike the rest of pattern_db, this module uses runtime `sqlx::query_as()`
+//! instead of compile-time `sqlx::query_as!()` macros. This is intentional:
+//!
+//! 1. **Virtual table syntax** - `WHERE embedding MATCH ? AND k = ?` is
+//!    sqlite-vec specific, not standard SQL. sqlx's compile-time checker
+//!    doesn't understand it.
+//!
+//! 2. **Table created at runtime** - The `embeddings` virtual table is created
+//!    via `ensure_embeddings_table()`, not in migrations. sqlx's offline mode
+//!    can't see it.
+//!
+//! 3. **Dynamic dimensions** - Table definition uses `float[{dimensions}]`
+//!    which varies per constellation.
+//!
+//! 4. **Extension-specific types** - Vector columns and the magic `distance`
+//!    column from KNN queries don't map to sqlx-known types.
+//!
+//! The tradeoff is acceptable: vector queries are isolated here, patterns are
+//! simple and stable, and we test at runtime anyway.

+//!
+//! The bot uses `pattern_auth::DiscordBotConfig` for configuration.
+//! Configuration can be loaded from:
+//! - Environment variables via `DiscordBotConfig::from_env()`
+//! - Database via `AuthDb::get_discord_bot_config()`
+//!
+//! The config should be loaded once at startup and passed to the bot.
+//! There are NO runtime environment variable reads in this crate.

+This document catalogues all TODOs, FIXMEs, stubs, and incomplete implementations found in the Pattern codebase. Items are organized by severity and then by crate.

+
+### Design decisions to revisit
+
+| Location | Issue |
+|----------|-------|
+| `pattern_core/src/context/builder.rs:944` | Panics on non-Text content - may need graceful handling |
+| `pattern_macros/src/lib.rs:1169,1186` | Panics on unknown table names - no fallback |
+| `pattern_core/src/memory/store.rs` | MemoryStore trait has many convenience methods (`append_to_block`, `replace_in_block`, etc.) that may be redundant now that StructuredDocument has a richer interface (`import_from_json`, `export_for_editing`, etc.). Consider consolidating - callers can use `get_block()` + document methods + `mark_dirty()`/`persist_block()` directly. |

-# Database API Reference
-
-This document provides a comprehensive reference for Pattern's database operations and types.
-
-## Core Types
-
-### ID Types
-
-All entities use strongly-typed IDs for compile-time safety:
-
-```rust
-use pattern_core::id::{UserId, AgentId, MemoryId, ConversationId, MessageId, TaskId};
-
-// Generate new IDs
-let user_id = UserId::generate();
-let agent_id = AgentId::generate();
-
-// Parse from strings
-let user_id = UserId::parse("user-123-456")?;
-
-// Convert to string
-let id_string = user_id.to_string();
-
-// Get nil/empty ID
-let nil_id = UserId::nil();
-```
-
-### Database Connection
-
-```rust
-use pattern_core::db::{DatabaseConfig, VectorStore};
-use pattern_core::db::embedded::EmbeddedDatabase;
-
-// Create embedded database
-let config = DatabaseConfig::Embedded {
-    path: "./pattern.db".to_string(),
-    strict_mode: false,
-};
-
-let db = EmbeddedDatabase::connect(config).await?;
-
-// Run migrations
-use pattern_core::db::migration::MigrationRunner;
-MigrationRunner::run_migrations(&db).await?;
-```
-
-## User Operations
-
-### Create User
-
-```rust
-use pattern_core::db::ops::create_user;
-
-let user = create_user(
-    &db,
-    None, // Optional ID, will generate if None
-    serde_json::json!({
-        "theme": "dark",
-        "timezone": "America/New_York"
-    }),
-    serde_json::json!({
-        "source": "discord",
-        "discord_id": "123456789"
-    }),
-).await?;
-```
-
-### Get User
-
-```rust
-use pattern_core::db::ops::get_user;
-
-let user = get_user(&db, user_id).await?;
-match user {
-    Some(user) => println!("Found user: {}", user.id),
-    None => println!("User not found"),
-}
-```
-
-### Get User with Agents
-
-```rust
-use pattern_core::db::ops::get_user_with_agents;
-
-let (user, agents) = get_user_with_agents(&db, user_id)
-    .await?
-    .ok_or("User not found")?;
-
-println!("User {} has {} agents", user.id, agents.len());
-```
-
-## Agent Operations
-
-### Create Agent
-
-```rust
-use pattern_core::db::ops::create_agent;
-use pattern_core::agent::{AgentType, AgentState};
-
-let agent = create_agent(
-    &db,
-    user_id,
-    AgentType::Pattern, // or AgentType::Custom("my-type".to_string())
-    "Pattern".to_string(),
-    "You are Pattern, the ADHD support orchestrator".to_string(),
-    serde_json::json!({
-        "model": "gpt-4",
-        "temperature": 0.7
-    }),
-    AgentState::Ready,
-).await?;
-```
-
-### Get User's Agents
-
-```rust
-use pattern_core::db::ops::get_user_agents;
-
-let agents = get_user_agents(&db, user_id).await?;
-for agent in agents {
-    println!("{}: {} ({})", agent.id, agent.name, agent.agent_type.as_str());
-}
-```
-
-### Update Agent State
-
-```rust
-use pattern_core::db::ops::update_agent_state;
-
-update_agent_state(
-    &db,
-    agent_id,
-    AgentState::Processing,
-).await?;
-
-// Or with cooldown
-use chrono::{Utc, Duration};
-update_agent_state(
-    &db,
-    agent_id,
-    AgentState::Cooldown {
-        until: Utc::now() + Duration::minutes(5)
-    },
-).await?;
-```
-
-## Memory Operations
-
-### Create Memory Block
-
-```rust
-use pattern_core::db::ops::create_memory;
-
-// Without embeddings
-let memory = create_memory(
-    &db,
-    None, // No embedding provider
-    agent_id,
-    "user_context".to_string(),
-    "User prefers dark themes and works in EST timezone".to_string(),
-    Some("User preferences".to_string()),
-    serde_json::json!({
-        "importance": "high",
-        "source": "onboarding"
-    }),
-).await?;
-
-// With embeddings
-use pattern_core::embeddings::EmbeddingProvider;
-let memory = create_memory(
-    &db,
-    Some(&embedding_provider),
-    agent_id,
-    "user_context".to_string(),
-    "User has ADHD and benefits from gentle reminders".to_string(),
-    None,
-    serde_json::json!({}),
-).await?;
-```
-
-### Search Memories by Similarity
-
-```rust
-use pattern_core::db::ops::search_memories;
-
-let results = search_memories(
-    &db,
-    &embedding_provider,
-    agent_id,
-    "user preferences and settings",
-    10, // limit
-).await?;
-
-for (memory, score) in results {
-    println!("Score {:.3}: {}", score, memory.content);
-}
-```
-
-### Get Memory by Label
-
-```rust
-use pattern_core::db::ops::get_memory_by_label;
-
-let memory = get_memory_by_label(
-    &db,
-    agent_id,
-    "user_context",
-).await?;
-```
-
-## Vector Search
-
-### Direct Vector Search
-
-```rust
-use pattern_core::db::{VectorStore, SearchFilter};
-
-// Search with filter
-let filter = SearchFilter {
-    where_clause: Some("is_active = true AND created_at > '2025-01-01'".to_string()),
-    params: vec![],
-};
-
-let results = db.vector_search(
-    "memory_blocks",
-    "embedding",
-    &query_vector, // f32 array
-    20, // limit
-    Some(filter),
-).await?;
-```
-
-### Create Vector Index
-
-```rust
-use pattern_core::db::DistanceMetric;
-
-db.create_vector_index(
-    "memory_blocks",
-    "embedding",
-    384, // dimensions
-    DistanceMetric::Cosine,
-).await?;
-```
-
-## Schema Types
-
-### User
-
-```rust
-pub struct User {
-    pub id: UserId,
-    pub created_at: chrono::DateTime<chrono::Utc>,
-    pub updated_at: chrono::DateTime<chrono::Utc>,
-    pub settings: HashMap<String, serde_json::Value>,
-    pub metadata: HashMap<String, serde_json::Value>,
-}
-```
-
-### Agent
-
-```rust
-pub struct Agent {
-    pub id: AgentId,
-    pub user_id: UserId,
-    pub agent_type: AgentType,
-    pub name: String,
-    pub system_prompt: String,
-    pub config: serde_json::Value,
-    pub state: AgentState,
-    pub created_at: chrono::DateTime<chrono::Utc>,
-    pub updated_at: chrono::DateTime<chrono::Utc>,
-    pub is_active: bool,
-}
-```
-
-### MemoryBlock
-
-```rust
-pub struct MemoryBlock {
-    pub id: MemoryId,
-    pub agent_id: AgentId,
-    pub label: String,
-    pub content: String,
-    pub description: Option<String>,
-    pub embedding: Vec<f32>,
-    pub embedding_model: String,
-    pub metadata: serde_json::Value,
-    pub created_at: chrono::DateTime<chrono::Utc>,
-    pub updated_at: chrono::DateTime<chrono::Utc>,
-    pub is_active: bool,
-}
-```
-
-## Error Handling
-
-All database operations return `Result<T, DatabaseError>`:
-
-```rust
-use pattern_core::db::DatabaseError;
-
-match create_user(&db, None, settings, metadata).await {
-    Ok(user) => println!("Created user {}", user.id),
-    Err(DatabaseError::ConnectionFailed { .. }) => {
-        eprintln!("Database connection failed");
-    }
-    Err(DatabaseError::QueryFailed(e)) => {
-        eprintln!("Query failed: {}", e);
-    }
-    Err(e) => eprintln!("Database error: {}", e),
-}
-```
-
-## Best Practices
-
-1. **Always use typed IDs**: Never use raw strings for entity IDs
-2. **Handle None cases**: Many get operations return `Option<T>`
-3. **Use transactions for multi-step operations** (when available)
-4. **Keep embeddings consistent**: Use the same model throughout
-5. **Index frequently searched fields**: Use appropriate indexes for performance
-
-## SurrealDB Query Patterns
-
-### Full-Text Search
-
-Pattern uses SurrealDB's `@@` operator for full-text search with BM25 ranking:
-
-```sql
--- Search archival memories
-SELECT * FROM mem
-WHERE (<-agent_memories<-agent:⟨agent_uuid⟩..)
-AND memory_type = 'archival'
-AND value @@ $search_term
-LIMIT $limit;
-
--- Search messages by content
-SELECT * FROM message
-WHERE (<-agent_messages<-agent:⟨agent_uuid⟩..)
-AND content @@ $search_query
-AND created_at >= $start_time
-ORDER BY position DESC
-LIMIT $limit;
-```
-
-### Graph Traversal
-
-Use SurrealDB's graph notation for relationship queries:
-
-```sql
--- Get all memories for an agent (through edge entity)
-SELECT * FROM mem
-WHERE (<-agent_memories<-agent:⟨agent_uuid⟩..);
-
--- Get agent's conversations
-SELECT * FROM conversation
-WHERE (<-agent_conversations<-agent:⟨agent_uuid⟩..);
-```
-
-### Pre-Computed Table Views
-
-SurrealDB's pre-computed views provide event-based, incrementally updating materialized views:
-
-```sql
--- Agent activity statistics (auto-updates on message insert)
-DEFINE TABLE agent_activity TYPE NORMAL AS
-SELECT
-    count() AS message_count,
-    time::max(created_at) AS last_active,
-    ->agent.id AS agent_id,
-    ->agent.name AS agent_name,
-    array::distinct(->conversation.id) AS active_conversations
-FROM message
-GROUP BY agent_id, agent_name;
-
--- Memory usage analytics (auto-updates on memory access)
-DEFINE TABLE memory_usage TYPE NORMAL AS
-SELECT
-    count() AS access_count,
-    time::max(accessed_at) AS last_accessed,
-    ->agent.id AS agent_id,
-    ->agent.name AS agent_name,
-    label,
-    memory_type
-FROM mem
-WHERE accessed_at IS NOT NULL
-GROUP BY agent_id, agent_name, label, memory_type;
-
--- Tool usage patterns (auto-updates on tool call)
-DEFINE TABLE tool_usage TYPE NORMAL AS
-SELECT
-    count() AS call_count,
-    ->agent.id AS agent_id,
-    ->agent.name AS agent_name,
-    tool_name,
-    array::group(RETURN {

-// Search with filters
-let messages: Vec<Message> = db

-        SELECT * FROM message
-        WHERE agent_id = $agent_id
-        AND content @@ $query
-        AND role = $role
-        AND created_at BETWEEN $start AND $end
-        ORDER BY position DESC
-        LIMIT $limit
-    "#)
-    .bind(("agent_id", agent_id))
-    .bind(("query", search_query))
-    .bind(("role", "assistant"))
-    .bind(("start", start_time))
-    .bind(("end", end_time))
-    .bind(("limit", 50))
-    .await?
-    .take(0)?;
-```

-### Important Notes
-
-1. **Pre-computed views update automatically** - No triggers needed
-2. **Views only trigger on FROM table changes** - Deleting an agent won't update agent_activity
-3. **Initial view creation can be slow** - Index appropriately
-4. **Use parameter binding** - Never concatenate SQL strings
-5. **Graph notation `<-relation<-` is powerful** - Traverses relationships efficiently

-- `insert_archival_memory()` - Add new archival memories
-- `delete_archival_memory()` - Remove archival memories
-- `count_archival_memories()` - Get archival memory count
+Tools access memory through the `MemoryStore` trait:

 ## Overview
 
-The context building system in `pattern-core` provides a complete framework for creating stateful agents on top of stateless LLM APIs. It follows the MemGPT/Letta pattern of agentic context engineering, where agents manage their own memory and context window.
+The context building system assembles model requests from memory blocks, message history, and tools. It's the bridge between Pattern's stateful agent infrastructure and stateless LLM APIs.
 
 ## Architecture
 
-### Core Components
+### ContextBuilder
 
-1. **AgentContext** - The complete context ready to send to an LLM
-2. **ContextBuilder** - Fluent builder for constructing contexts
-3. **AgentState** - Persistent state management between conversations
-4. **MessageCompressor** - Strategies for handling context overflow
-5. **Memory System** - MemGPT-style memory blocks with character limits
-
-### Key Features
-
-- **Stateful agents on stateless protocols** - Maintains conversation history and memory
-- **Automatic context compression** - Multiple strategies for handling overflow
-- **Type-safe tool integration** - Tools are properly typed and validated
-- **Model-agnostic** - Works with any provider through the genai crate
-- **Memory persistence** - Core memory blocks persist between conversations
-
-## Usage Examples
-
-### Basic Context Building

-## Memory Management
+The `build()` method:
+1. Builds system prompt from Core and Working memory blocks
+2. Retrieves and compresses message history
+3. Applies model-specific adjustments (e.g., Gemini first-message requirements)
+4. Converts tools to genai format
 
-### Memory Blocks
+### System Prompt Assembly
 
-Memory blocks follow the MemGPT pattern with permissions and memory types:
+The system prompt is built in order:
+1. Base instructions (custom or default)
+2. Core blocks (always in context)
+3. Working blocks (pinned or referenced by batch)
+4. Activity section (if renderer provided)
+5. Tool execution rules (if any)
 
-```rust
-pub struct MemoryBlock {
-    /// Unique identifier
-    pub id: MemoryId,
-    
-    /// The user who owns this memory
-    pub owner_id: UserId,
-    
-    /// Label like "persona", "human", "context"
-    pub label: CompactString,
-
-    /// The actual memory content
-    pub value: String,
-
-    /// Description of what this block contains
-    pub description: Option<String>,
-    
-    /// Type: Core (always in context), Working (swappable), Archival (searchable)
-    pub memory_type: MemoryType,
-    
-    /// Permission level (ReadOnly, Partner, Human, Append, ReadWrite, Admin)
-    pub permission: MemoryPermission,
-    
-    /// Whether pinned (can't be swapped out)
-    pub pinned: bool,
-    
-    /// Embedding for semantic search (if any)
-    pub embedding: Option<Vec<f32>>,
-}
-```
+Each block renders as:
+```xml
+<block:label permission="ReadWrite">
+Block description (if include_descriptions enabled)
 
-### Core Memory Operations
+Rendered content from StructuredDocument
+</block:label>
+```
 
-```rust
-// Append to a memory block
-agent.append_to_memory_block("human", "Prefers morning meetings")?;
-
-// Replace content in a memory block
-agent.replace_in_memory_block(
-    "context",
-    "working on project X",
-    "completed project X, now working on project Y"
-)?;
-
-// Update entire block
-agent.update_memory_block("persona", "Updated personality description")?;
+Shared blocks include attribution:
+```xml
+<block:shared_notes permission="Append" shared_from="Archive">
+Content shared from another agent
+</block:shared_notes>
 ```
 
-## Message Compression
+## Memory System
 
-When conversation history exceeds the context window, various compression strategies are available:
+### MemoryStore Trait
 
-### Truncation (Default)
-```rust
-CompressionStrategy::Truncate { keep_recent: 50 }
-```

 ```
 
-### Importance-Based Selection
+### MemoryCache
+
+The default `MemoryStore` implementation using Loro CRDT with write-through to SQLite:
+
 ```rust
-CompressionStrategy::ImportanceBased {
-    keep_recent: 20,
-    keep_important: 10,
-}
+let dbs = ConstellationDatabases::open("./constellation.db", "./auth.db").await?;
+let memory = MemoryCache::new(dbs.clone());
 ```
 
-### Time-Decay Compression
+Features:
+- Lazy loading: blocks loaded on first access
+- Write-through: changes persisted to SQLite
+- Delta updates: exports only changes since last persist
+- Eviction: LRU-based cache management
+
+### Block Types
+
 ```rust
-CompressionStrategy::TimeDecay {
-    compress_after_hours: 24.0,
-    min_keep_recent: 10,
+pub enum BlockType {
+    Core,     // Always in context, cannot be swapped out
+    Working,  // Active working memory, can be swapped
+    Archival, // Long-term storage, searchable on demand
+    Log,      // Append-only log entries
 }
 ```
 
-## Context Configuration
-
-The `ContextConfig` struct provides fine-grained control:
+### Memory Permissions
 
 ```rust
-pub struct ContextConfig {
-    /// Base system instructions
-    pub base_instructions: String,
-
-    /// Max characters per memory block
-    pub memory_char_limit: usize,
+pub enum MemoryPermission {
+    ReadOnly,   // Can only read
+    Partner,    // Requires partner (owner) permission to write
+    Human,      // Requires human permission to write
+    Append,     // Can append to existing content
+    ReadWrite,  // Can modify freely (default)
+    Admin,      // Total control, can delete
+}
+```
 
-    /// Max messages before compression
-    pub max_context_messages: usize,
+## Structured Documents (Loro CRDT)
 
-    /// Enable thinking/reasoning
-    pub enable_thinking: bool,
+### StructuredDocument
 
-    /// Tool usage rules
-    pub tool_rules: Vec<ToolRule>,
+Each memory block is backed by a `StructuredDocument` wrapping a Loro CRDT document:
 
-    /// Model-specific adjustments
-    pub model_adjustments: ModelAdjustments,
+```rust
+pub struct StructuredDocument {
+    doc: LoroDoc,
+    schema: BlockSchema,
+    permission: MemoryPermission,
+    label: String,
+    accessor_agent_id: Option<String>,
 }
 ```
 
-## Working with genai
+Operations check permissions via `is_system` flag:
+- System operations bypass permission checks
+- Agent operations respect the document's permission level
 
-The context builder produces output compatible with the genai crate:
+### Block Schemas
 
 ```rust
-// Build context
-let context = agent.build_context().await?;
-
-// Create genai request
-let request = genai::ChatRequest::new(
-    genai::chat::ChatRole::System,
-    context.system_prompt
-);
-
-// Add messages
-for message in context.messages {
-    request = request.with_message(message);
+pub enum BlockSchema {
+    Text { viewport: Option<Viewport> },
+    Map { fields: Vec<FieldDef> },
+    List { item_schema: Option<Box<BlockSchema>>, max_items: Option<usize> },
+    Log { display_limit: usize, entry_schema: LogEntrySchema },
+    Composite { sections: Vec<CompositeSection> },
 }
+```
 
-// Add tools
-for tool in context.tools {
-    request = request.with_tool(tool);
-}
+**Text**: Simple text content with optional viewport for large documents
+```rust
+doc.set_text("Hello, world!", is_system)?;
+doc.append_text(" More text.", is_system)?;
+doc.replace_text("Hello", "Hi", is_system)?;
+```
 
-// Execute with your chosen model
-let response = client.chat(model, request).await?;
+**Map**: Key-value fields with typed entries
+```rust
+doc.set_field("name", json!("Alice"), is_system)?;
+doc.set_text_field("status", "active", is_system)?;
+doc.append_to_list_field("tags", json!("important"), is_system)?;
+doc.increment_counter("score", 5, is_system)?;
 ```
 
-## Advanced Features
+**List**: Ordered collection
+```rust
+doc.push_item(json!({"task": "Review PR"}), is_system)?;
+doc.insert_item(0, json!({"task": "Urgent"}), is_system)?;
+doc.delete_item(1, is_system)?;
+```
 
-### Message Search
+**Log**: Append-only with display limit
+```rust
+doc.append_log_entry(json!({
+    "timestamp": "2025-01-01T00:00:00Z",
+    "message": "User logged in"
+}), is_system)?;
 
-Search through all messages including archived ones:
+// Get most recent entries (respects display_limit)
+let entries = doc.log_entries(None);
+```
 
+**Composite**: Multiple sections with independent schemas
 ```rust
-let results = agent.search_messages("task management", page: 0, page_size: 10);
-for message in results {
-    println!("{}: {}", message.role, message.text_content().unwrap_or_default());
-}
+doc.set_text_in_section("notes here", "notes", is_system)?;
+doc.set_field_in_section("count", 42, "stats", is_system)?;
 ```
 
-### State Checkpoints
-
-Create and restore agent state checkpoints:
+### Subscriptions
 
+Documents support change subscriptions:
 ```rust
-// Create checkpoint
-let checkpoint = agent.checkpoint();
+let _sub = doc.subscribe_root(Arc::new(|event| {
+    println!("Document changed: {:?}", event.triggered_by);
+}));
 
-// ... do some operations ...
-
-// Restore if needed
-agent.restore_from_checkpoint(checkpoint)?;
+doc.increment_counter("counter", 1, true)?;
+doc.commit(); // Triggers subscriptions
 ```
 
-### Agent Statistics
-
-Get insights into agent usage:
+### Rendering
 
+Documents render to string for LLM context:
 ```rust
-let stats = agent.get_stats();
-println!("Total messages: {}", stats.total_messages);
-println!("Tool calls: {}", stats.total_tool_calls);
-println!("Compressions: {}", stats.compression_events);
+let content = doc.render();
 ```
 
-## Tool Rules Integration
+Rendering respects schema:
+- Text: Plain content (with viewport windowing if configured)
+- Map: `field_name: value` format
+- List: Numbered or checkbox format
+- Log: Timestamped entries (newest first)
+- Composite: Sections with `=== section_name ===` headers
 
-The context builder automatically includes tool usage rules and enforcement information in the system prompt when agents have configured tool rules.
+Read-only fields/sections are marked in rendered output:
+```
+status [read-only]: active
+=== diagnostics [read-only] ===
+```
 
-### How Tool Rules Affect Context
+## Context Configuration
 
-1. **System Prompt Enhancement**: Tool rules are converted to natural language and included in the system prompt
-2. **Tool Descriptions**: Each tool's `usage_rule()` is appended to its description
-3. **Rule Enforcement**: The agent's tool rule engine validates all tool calls before execution
+```rust
+pub struct ContextConfig {
+    pub default_limits: ModelContextLimits,
+    pub model_overrides: HashMap<String, ModelContextLimits>,
+    pub include_descriptions: bool,   // Include block descriptions in prompt
+    pub include_schemas: bool,        // Include schema definitions
+    pub activity_entries_limit: usize, // Recent activity to show
+    pub compression_strategy: CompressionStrategy,
+    pub max_messages_cap: usize,      // Hard limit on messages
+}
+```
 
-### Example with Tool Rules
+### Model Context Limits
 
 ```rust
-// Create agent with tool rules
-let rules = vec![
-    ToolRule {
-        tool_name: "send_message".to_string(),
-        rule_type: ToolRuleType::ExitLoop,
-        conditions: vec![],
-        priority: 8,
-        metadata: None,
-    },
-    ToolRule {
-        tool_name: "recall".to_string(), 
-        rule_type: ToolRuleType::ContinueLoop,
-        conditions: vec![],
-        priority: 1,
-        metadata: None,
-    },
-];
+pub struct ModelContextLimits {
+    pub max_tokens: usize,           // Total context window
+    pub memory_tokens: usize,        // Reserved for memory blocks
+    pub history_tokens: usize,       // Reserved for message history
+    pub reserved_response_tokens: usize,
+}
+```
 
-let agent = DatabaseAgent::new(
-    // ... other params ...
-    tool_rules: rules,
-);
+## Message Compression
 
-// When building context, tool rules are automatically included:
-// 1. Tool usage rules from each tool's usage_rule() method
-// 2. Natural language descriptions of configured rules
-// 3. Current rule state (e.g., remaining calls for MaxCalls rules)
+When history exceeds limits, compression strategies apply:
+
+```rust
+pub enum CompressionStrategy {
+    Truncate { keep_recent: usize },
+    RecursiveSummarization {
+        chunk_size: usize,
+        summarization_model: String,
+    },
+}
 ```
 
-### System Prompt with Rules
+The `MessageCompressor` handles batch-aware compression:
+- Complete batches are compressed together
+- Active batch (currently processing) is never compressed
+- Incomplete non-active batches are excluded
 
-The generated system prompt includes sections like:
+## Search
 
-```
-## Tool Usage Rules
+Unified search across memory content:
+
+```rust
+let options = SearchOptions::new()
+    .mode(SearchMode::Fts)  // or Vector, Hybrid, Auto
+    .content_types(vec![SearchContentType::Messages])
+    .limit(20);
 
-When using tools, follow these rules:
-- send_message: the conversation will end when called
-- recall: continues the conversation loop when called
-- api_request: Maximum 3 calls allowed (2 remaining)
-- validate: Can only be called after: load_data
+let results = memory.search(agent_id, "task management", options).await?;
 ```
 
-## Best Practices
+Search modes:
+- **Fts**: FTS5 keyword search with BM25 scoring
+- **Vector**: sqlite-vec similarity search
+- **Hybrid**: Combines both with fusion
+- **Auto**: Chooses based on embedder availability
 
-1. **Set appropriate memory limits** - Keep character limits reasonable for your model's context window
-2. **Choose compression strategy wisely** - Recursive summarization preserves more information but costs more tokens
-3. **Update memory regularly** - Keep memory blocks current with learned information
-4. **Monitor token usage** - Use `context.metadata.total_tokens_estimate` to track usage
-5. **Handle compression events** - Important information might be compressed, ensure critical data is in memory blocks
+## Ephemeral Blocks
 
-## Integration with Tools
+Working blocks can be pinned or ephemeral:
 
-The context builder seamlessly integrates with the type-safe tool system:
+- **Pinned**: Always loaded into context
+- **Ephemeral** (unpinned): Only loaded when referenced
 
+DataStream notifications can reference blocks:
 ```rust
-// Register tools (DashMap allows concurrent access)
-let registry = ToolRegistry::new();
-registry.register(SearchTool);
-registry.register(MemoryTool);
-
-// Add to context
-let context = ContextBuilder::new(agent_id, config)
-    .with_tools_from_registry(&registry)
-    .build()?;
-
-// Tools are automatically formatted for the LLM
-// with proper schemas and usage rules
+let builder = ContextBuilder::new(&memory, &config)
+    .for_agent("entropy")
+    .with_batch_blocks(vec!["ephemeral-block-id".to_string()]);
 ```
 
-## Error Handling
+This loads the specified blocks even if unpinned, allowing data sources to inject temporary context.
+
+## Tool Rules Integration
 
-The system uses rich error types with miette for detailed diagnostics:
+Tool rules control execution flow and are included in the system prompt:
 
 ```rust
-match agent.update_memory_block("nonexistent", "value") {
-    Err(CoreError::MemoryNotFound { block_name, available_blocks, .. }) => {
-        println!("Block '{}' not found. Available: {:?}", block_name, available_blocks);
-    }
-    Err(e) => return Err(e),
-    Ok(_) => {}
+pub enum ToolRuleType {
+    ExitLoop,           // Tool call ends the agent's turn
+    ContinueLoop,       // Tool call continues processing
+    MaxCalls(u32),      // Maximum calls allowed per turn
+    RequiresPrior(String), // Only callable after another tool
 }
 ```
+
+Example rules:
+```rust
+let rules = vec![
+    ToolRule::exit_loop("send_message".to_string()),
+    ToolRule::continue_loop("search".to_string()),
+    ToolRule::max_calls("api_request".to_string(), 3),
+    ToolRule::start_constraint("context".to_string()),
+];
+
+let request = ContextBuilder::new(&memory, &config)
+    .for_agent("entropy")
+    .with_tool_rules(rules)
+    .build()
+    .await?;
+```
+
+Generated system prompt includes:
+```
+# Tool Execution Rules
+
+- Call `context` first before any other tools
+- The conversation will end after calling `send_message`
+- The conversation will be continued after calling `search`
+- Call `api_request` at most 3 times
+```
+
+## Best Practices
+
+1. **Use appropriate block types**: Core for identity, Working for active context, Log for audit trails
+2. **Set permissions carefully**: ReadOnly for system-managed data, Append for logs, ReadWrite for agent-editable content
+3. **Leverage schemas**: Map schema for structured data, Composite for multi-section documents
+4. **Monitor token usage**: Check ContextMetadata after building
+5. **Use ephemeral blocks**: For notification-specific context that shouldn't persist in every request

-# Pattern Core Database Backend
-
-This document describes the database backend implementation for Pattern Core, including the data model, embedding support, and migration system.
-
-**Status**: Core functionality implemented. Embeddings and vector search still need to be completed.
-
-## Architecture Overview
-
-The database backend is designed with flexibility in mind, supporting both embedded and remote databases through a trait-based abstraction layer.
-
-### Key Components
-
-1. **Database Traits** (`db/mod.rs`)
-   - `DatabaseBackend`: Core database operations
-   - `DatabaseOperations`: Generic operations (transactions)
-   - `VectorStore`: Vector search capabilities
-   - `Transaction`: Transaction operations
-
-2. **Embedded Implementation** (`db/embedded.rs`)
-   - Uses SurrealDB with SurrealKv (pure Rust backend)
-   - Supports vector indexes via HNSW
-   - In-process database for single-node deployments
-
-3. **Schema Management** (`db/schema.rs`)
-   - Strongly-typed table definitions
-   - Model structs with serde serialization
-   - Vector embedding support built-in
-
-4. **Direct Operations** (`db/ops.rs`)
-   - Simple function-based data access
-   - Type-safe operations without abstraction overhead
-   - No unnecessary repository pattern
-
-5. **Migration System** (`db/migration.rs`)
-   - Simple version-based migrations
-   - Automatic schema updates on startup
-   - Rollback support for development
-
-## Data Model
-
-The database uses the Entity macro system to define tables. Core entities are defined using `#[derive(Entity)]` which automatically generates the schema.
-
-### Core Tables
-
-#### System Metadata
-```sql
-DEFINE TABLE system_metadata SCHEMALESS;
-DEFINE FIELD embedding_model ON system_metadata TYPE string;
-DEFINE FIELD embedding_dimensions ON system_metadata TYPE int;
-DEFINE FIELD schema_version ON system_metadata TYPE int;
-DEFINE FIELD created_at ON system_metadata TYPE datetime;
-DEFINE FIELD updated_at ON system_metadata TYPE datetime;
-```
-
-#### Primary Entities (via Entity macro)
-
-**Users**
-- Generated from `User` struct in `users` module
-- Fields: id, username, email, settings, metadata, created_at, updated_at
-- Relations: owns agents, owns constellations
-
-**Agents** 
-- Generated from `AgentRecord` struct
-- Fields: id, name, agent_type, state, model config, context settings, statistics
-- Relations: owned by user, has memories, has messages, assigned tasks
-
-**Memory Blocks**
-- Generated from `MemoryBlock` struct  
-- Fields: id, owner_id, label, value, description, memory_type, permission, embedding
-- Memory types: Core (always in context), Working (swappable), Archival (searchable)
-- Permissions: ReadOnly, Partner, Human, Append, ReadWrite, Admin
-
-**Messages**
-- Generated from `Message` struct
-- Fields: id, role, content, metadata, embedding, created_at
-- Content types: Text, Parts (multimodal), ToolCalls, ToolResponses
-- Snowflake ID positioning for distributed ordering
-
-**Tasks**
-- Generated from `BaseTask` struct
-- Fields: id, title, description, status, priority, due_date, creator_id
-- Relations: parent/subtasks, assigned agent
-
-**Tool Calls**
-- Generated from `ToolCall` struct
-- Fields: id, agent_id, tool_name, parameters, result, error, duration_ms
-- Audit trail for all tool executions
-
-## Embedding Support
-
-The database backend integrates with the embeddings module to provide semantic search capabilities.
-
-### Embedding Providers
-
-1. **Candle (Local)** ✅
-   - Pure Rust implementation
-   - Supports BERT-based models
-   - Default: BAAI/bge-small-en-v1.5 (384 dims)
-
-2. **Cloud Providers** ✅
-   - OpenAI: text-embedding-3-small/large
-   - Cohere: embed-english-v3.0
-   - API key configuration required
-
-3. **Ollama** 🚧
-   - Stub implementation only
-   - Planned for future release
-
-### Embedding Storage
-
-- Vectors stored directly in SurrealDB
-- HNSW indexes for fast similarity search
-- Cosine distance metric for text embeddings
-- Automatic re-embedding on content updates
-
-### Vector Search (TODO)
-
-```rust
-// Planned: Semantic memory search
-// Currently embeddings are stored but search is not implemented
-let results = db::ops::search_archival_memories(
-    &db,
-    agent_id,
-    "query text",
-    10
-).await?;
-```
-
-## Direct Operations
-
-All database operations are exposed as simple functions in `db::ops`:
-
-### User Operations
-- `create_user()` - Create a new user with constellation
-- `get_user_by_id()` - Get user by ID
-- `get_user_by_username()` - Get user by username
-
-### Agent Operations  
-- `create_agent_for_user()` - Create agent in user's constellation
-- `get_agent_with_relations()` - Get agent with memories and messages
-- `persist_agent()` - Save full agent state
-- `persist_agent_message()` - Save message with relation type
-
-### Memory Operations
-- `create_memory_block()` - Create memory with permissions
-- `get_agent_memories()` - Get all memories for an agent
-- `search_archival_memories()` - Full-text search (BM25)
-- `insert_archival_memory()` - Add to archival storage
-- `delete_archival_memory()` - Remove from archival
-
-### Group Operations
-- `create_group_for_user()` - Create agent group
-- `add_agent_to_group()` - Add member with role
-- `get_group_members()` - List group agents
-- `list_groups_for_user()` - User's groups
-
-This approach keeps the code simple and direct without unnecessary abstraction layers.
-
-## Configuration
-
-### Database Configuration
-```toml
-[database]
-type = "embedded"
-path = "./pattern.db"
-strict_mode = false
-
-# Or for remote (when implemented)
-# type = "remote"
-# url = "ws://localhost:8000"
-# namespace = "pattern"
-# database = "main"
-```
-
-### Embedding Configuration
-```toml
-[embeddings]
-provider = "candle"
-model = "BAAI/bge-small-en-v1.5"
-
-# Or for cloud
-# provider = "openai"
-# model = "text-embedding-3-small"
-# api_key = "${OPENAI_API_KEY}"
-```
-
-## Migration System
-
-The migration system ensures database schema consistency across versions:
-
-1. **Automatic Migration**: Runs on startup
-2. **Version Tracking**: Stored in system_metadata
-3. **Idempotent**: Safe to run multiple times
-4. **Rollback Support**: For development/testing
-
-### Adding a Migration
-
-1. Add a new migration function in `migration.rs`
-2. Increment the version check in `run_migrations()`
-3. Implement the schema changes
-4. Test with both fresh and existing databases
-
-## Feature Flags
-
-The database backend supports multiple configurations via feature flags:
-
-- `surreal-embedded`: Embedded SurrealDB (default) ✅
-- `surreal-remote`: Remote SurrealDB connection 🚧 Not implemented
-- `embed-candle`: Local Candle embeddings (default) ✅
-- `embed-cloud`: Cloud embedding providers (default) ✅
-- `embed-ollama`: Ollama embedding support 🚧 Stub only
-
-## Testing
-
-The database module includes comprehensive tests:
-
-1. **Unit Tests**: Direct operation functions
-2. **Integration Tests**: Full database workflows
-3. **Migration Tests**: Schema update verification
-4. **Embedding Tests**: Vector operations
-
-Run tests with:
-```bash
-cargo test --features surreal-embedded,embed-candle
-```
-
-## Performance Considerations
-
-1. **Connection Pooling**: Single connection for embedded DB
-2. **Vector Indexes**: HNSW for approximate nearest neighbor
-3. **Batch Operations**: Supported for embeddings
-4. **Caching**: Consider caching frequent queries in production
-
-## Future Enhancements
-
-1. **Remote Database Support**: For distributed deployments
-2. **Complete Ollama Provider**: Full implementation of stub
-3. **Additional Embedding Providers**: Local ONNX models
-4. **Vector Index Tuning**: Configurable HNSW parameters
-5. **Query Optimization**: Prepared statements, query plans
-6. **Backup/Restore**: Automated database backups

-# Entity System Architecture
-
-Pattern uses a sophisticated macro-based entity system that provides compile-time safety, automatic type conversions, and seamless integration with SurrealDB's graph database features.
-
-## Overview
-
-The entity system is built around the `#[derive(Entity)]` proc macro which generates all the boilerplate code needed for database entities, including:
-
-- Storage model structs with SurrealDB-compatible types
-- Automatic conversions between domain types and storage types
-- Schema generation with proper field definitions
-- Relation management using SurrealDB's RELATE queries
-- Convenient methods for storing and loading entities with their relations
-
-## Basic Usage
-
-### Simple Entity
-
-```rust
-use pattern_macros::Entity;
-use pattern_core::id::UserId;
-use chrono::{DateTime, Utc};
-use serde::{Serialize, Deserialize};
-
-#[derive(Debug, Clone, Entity, Serialize, Deserialize)]
-#[entity(entity_type = "user")]
-pub struct User {
-    pub id: UserId,
-    pub username: String,
-    pub email: Option<String>,
-    pub created_at: DateTime<Utc>,
-    pub updated_at: DateTime<Utc>,
-}
-```
-
-This generates:
-- `UserDbModel` struct with SurrealDB types
-- `DbEntity` trait implementation
-- Schema definition for the `user` table
-
-### Using the Entity
-
-```rust
-// Create a new user
-let user = User {
-    id: UserId::generate(),
-    username: "alice".to_string(),
-    email: Some("alice@example.com".to_string()),
-    created_at: Utc::now(),
-    updated_at: Utc::now(),
-};
-
-// Store to database
-let stored = user.store_with_relations(&db).await?;
-
-// Load from database
-let loaded = User::load_with_relations(&db, user_id).await?
-    .expect("User not found");
-```
-
-## Field Attributes
-
-### Skip Fields
-
-Fields marked with `#[entity(skip)]` are not persisted to the database:
-
-```rust
-#[derive(Debug, Clone, Entity, Serialize, Deserialize)]
-#[entity(entity_type = "agent")]
-pub struct Agent {
-    pub id: AgentId,
-    pub name: String,
-    
-    #[entity(skip)]
-    pub runtime_state: AgentState,  // Computed at runtime, not stored
-}
-```
-
-### Custom Storage Types
-
-Use `#[entity(db_type = "Type")]` to specify custom storage conversions:
-
-```rust
-#[derive(Debug, Clone, Entity, Serialize, Deserialize)]
-#[entity(entity_type = "task")]
-pub struct Task {
-    pub id: TaskId,
-    pub title: String,
-    
-    // Store as flexible JSON object
-    pub metadata: serde_json::Value,
-    
-    // Store Vec<String> as comma-separated string
-    #[entity(db_type = "String")]
-    pub tags: Vec<String>,
-}
-```
-
-### Relations
-
-Fields marked with `#[entity(relation = "edge_name")]` are stored as graph relations:
-
-```rust
-#[derive(Debug, Clone, Entity, Serialize, Deserialize)]
-#[entity(entity_type = "user")]
-pub struct User {
-    pub id: UserId,
-    pub username: String,
-    
-    // ID-only relations (just store/load IDs)
-    #[entity(relation = "owns")]
-    pub owned_agent_ids: Vec<AgentId>,
-    
-    // Full entity relations (store/load complete entities)
-    #[entity(relation = "created")]
-    pub created_tasks: Vec<Task>,
-}
-```
-
-## Relation Management
-
-### How Relations Work
-
-Instead of foreign keys, the entity system uses SurrealDB's RELATE to create edge tables:
-
-```
-user:123 -> owns -> agent:456
-user:123 -> created -> task:789
-```
-
-This creates bidirectional relationships that can be traversed efficiently.
-
-### ID vs Entity Relations
-
-To avoid circular dependencies, you can choose between:
-
-1. **ID Relations**: Store only the ID, load only the ID
-   ```rust
-   #[entity(relation = "owns")]
-   pub owned_agent_ids: Vec<AgentId>,
-   ```
-
-2. **Entity Relations**: Store and load full entities
-   ```rust
-   #[entity(relation = "created")]
-   pub created_tasks: Vec<Task>,
-   ```
-
-### Manual Relation Management
-
-```rust
-// Store relations manually
-user.store_relations(&db).await?;
-
-// Load relations manually
-user.load_relations(&db).await?;
-```
-
-### Automatic Relation Management
-
-The convenience methods handle relations automatically:
-
-```rust
-// Stores entity AND all relations
-let stored = user.store_with_relations(&db).await?;
-
-// Loads entity AND all relations
-let loaded = User::load_with_relations(&db, user_id).await?;
-```
-
-## Generated Methods
-
-The `#[derive(Entity)]` macro generates the following methods:
-
-### Instance Methods
-
-```rust
-impl User {
-    // Store all relation fields to the database
-    pub async fn store_relations(&self, db: &Surreal<Db>) -> Result<(), DatabaseError>;
-    
-    // Load all relation fields from the database
-    pub async fn load_relations(&mut self, db: &Surreal<Db>) -> Result<(), DatabaseError>;
-    
-    // Store entity with all relations (upserts if exists)
-    pub async fn store_with_relations(&self, db: &Surreal<Db>) -> Result<Self, DatabaseError>;
-}
-
-## ID Handling and Record Keys
-
-Pattern’s ID types implement a Display that is human-friendly (e.g., `agent:abcd…`, `group:ef01…`). This is great for logs and CLI output, but must not be used when persisting or constructing record keys for the database.
-
-- Use `id.to_key()` when you need the raw record key (just the UUID-like portion) for persistence or composing IDs stored in other entities.
-- Use `RecordId::from(&id)` when binding IDs in SurrealDB queries (`.bind(("agent_id", RecordId::from(&agent_id)))`).
-- Avoid `id.to_string()` for any database-bound value. Display includes the table prefix, which can break UUID validations or schema expectations.
-
-Common pitfalls and fixes:
-- Tracker or cursor IDs derived from other IDs should use `.to_key()` rather than `.to_string()`.
-- When storing string keys (e.g., `MemoryId`, cursor keys), prefer the raw key: `let key = some_id.to_key();`.
-
-Caveat (rare acceptable `to_string()`):
-- Some IDs are intentionally not table-prefixed and their Display equals the raw key (for example `Did`, and `MessageId` where the key is an arbitrary string). In those specific cases, `to_string()` may be acceptable if and only if you expect the raw key string. When in doubt, prefer `.to_key()` or `RecordId::from(&id)`.
-
-Quick checklist:
-- Persistence: `to_key()` or `RecordId::from(&id)`
-- Display/logging: `to_string()`
-- Never concatenate Display-form IDs into other record keys
-
-Code review checklist:
-- Are any IDs converted with `.to_string()` and then used in DB paths, record keys, or binds? If yes, replace with `.to_key()` or `RecordId::from(&id)` unless it’s one of the rare exceptions above.
-- Are tuple APIs used correctly? Always pass `(table, id.to_key())` or `(table, id.to_record_id())`, not `(table, id.to_string())`.
-```
-
-### Associated Functions
-
-```rust
-impl User {
-    // Load entity with all relations
-    pub async fn load_with_relations(
-        db: &Surreal<Db>, 
-        id: Id<UserId>
-    ) -> Result<Option<Self>, DatabaseError>;
-}
-```
-
-### DbEntity Trait Implementation
-
-```rust
-impl DbEntity for User {
-    type DbModel = UserDbModel;
-    type Domain = Self;
-    type Id = UserId;
-    
-    fn to_db_model(&self) -> Self::DbModel;
-    fn from_db_model(db_model: Self::DbModel) -> Result<Self, EntityError>;
-    fn table_name() -> &'static str;
-    fn id(&self) -> Id<Self::Id>;
-    fn schema() -> TableDefinition;
-}
-```
-
-## Schema Generation
-
-The entity system automatically generates SurrealDB schema definitions:
-
-```sql
-DEFINE TABLE OVERWRITE user SCHEMALESS;
-DEFINE FIELD id ON TABLE user TYPE record;
-DEFINE FIELD username ON TABLE user TYPE string;
-DEFINE FIELD email ON TABLE user TYPE option<string>;
-DEFINE FIELD created_at ON TABLE user TYPE datetime;
-DEFINE FIELD updated_at ON TABLE user TYPE datetime;
-DEFINE TABLE OVERWRITE owns SCHEMALESS;
-DEFINE TABLE OVERWRITE created SCHEMALESS;
-```
-
-## Type Conversions
-
-The system automatically handles conversions between Rust types and SurrealDB types:
-
-| Rust Type | SurrealDB Storage Type |
-|-----------|------------------------|
-| `DateTime<Utc>` | `surrealdb::Datetime` |
-| `UserId`, `AgentId`, etc. | `surrealdb::RecordId` |
-| `Option<T>` | Nullable field |
-| `Vec<T>` | Array field |
-| `serde_json::Value` | FLEXIBLE object field |
-| `Vec<String>` with `db_type = "String"` | Comma-separated string |
-| Enums | String field (requires custom serialization) |
-
-### Enum Serialization
-
-Enums need custom serialization to work with SurrealDB's string field type:
-
-```rust
-#[derive(Debug, Clone, PartialEq, Eq, Hash)]
-pub enum BaseAgentType {
-    Assistant,
-    Custom(String),
-}
-
-impl Serialize for BaseAgentType {
-    fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>
-    where
-        S: serde::Serializer,
-    {
-        match self {
-            BaseAgentType::Assistant => serializer.serialize_str("assistant"),
-            BaseAgentType::Custom(s) => serializer.serialize_str(s),
-        }
-    }
-}
-
-impl<'de> Deserialize<'de> for BaseAgentType {
-    fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>
-    where
-        D: serde::Deserializer<'de>,
-    {
-        let s = String::deserialize(deserializer)?;
-        match s.as_str() {
-            "assistant" => Ok(BaseAgentType::Assistant),
-            custom => Ok(BaseAgentType::Custom(custom.to_string())),
-        }
-    }
-}
-```
-
-This ensures enums are stored as simple strings in the database, matching the schema's `TYPE string` declaration.
-
-## Advanced Usage
-
-### External Crates
-
-When using the macro outside of pattern-core:
-
-```rust
-#[derive(Debug, Clone, Entity, Serialize, Deserialize)]
-#[entity(entity_type = "user", crate_path = "::pattern_core")]
-pub struct User {
-    // ...
-}
-```
-
-### Complex Relations
-
-For many-to-many relationships with metadata:
-
-```rust
-// Edge table can store additional data
-user:123 -> assigned{priority: "high", deadline: "2024-01-15"} -> task:789
-```
-
-### Ordering Relations
-
-Relations are automatically ordered by ID to ensure consistent results:
-
-```sql
-SELECT id, ->owns->agent AS related_entities FROM $parent ORDER BY id ASC
-```
-
-## Best Practices
-
-1. **Use ID relations to avoid circular dependencies**
-   - If User has Tasks and Task has User, make one use IDs
-
-2. **Leverage skip fields for runtime state**
-   - Computed fields, caches, and temporary state shouldn't be stored
-
-3. **Use appropriate storage types**
-   - `serde_json::Value` for flexible data
-   - Custom `db_type` for optimized storage
-
-4. **Prefer convenience methods**
-   - `store_with_relations()` and `load_with_relations()` handle everything
-
-5. **Design relations thoughtfully**
-   - Consider query patterns when choosing between ID and entity relations
-   - Use edge metadata when relationships have properties
-
-## Migration from Old System
-
-If migrating from a foreign key-based system:
-
-1. Replace foreign key fields with relation fields:
-   ```rust
-   // Old
-   pub owner_id: UserId,
-   
-   // New
-   #[entity(relation = "owned_by")]
-   pub owner: User,
-   ```
-
-2. Update queries to use RELATE:
-   ```rust
-   // Old
-   task.owner_id = user.id;
-   
-   // New (handled automatically by store_with_relations)
-   task.owner = user;
-   ```
-
-3. Create migration queries to establish relations:
-   ```sql
-   -- Migrate foreign keys to relations
-   LET $tasks = SELECT * FROM task WHERE owner_id;
-   FOR $task IN $tasks {
-       RELATE $task.owner_id->owns->$task.id;
-   };
-   ```
-
-## Performance Considerations
-
-- **ID relations are cheap**: Only store/load record IDs
-- **Entity relations are fast**: SurrealDB's architecture fetches related entities efficiently without traditional joins
-- **Graph traversal is optimized**: Following relations is faster than SQL joins due to direct record linking
-- **Use batch operations**: Store multiple relations in one transaction
-- **Consider lazy loading**: Load relations only when needed for very large datasets
-- **Built-in indexing**: SurrealDB automatically optimizes relation traversals

+# Export System (CAR v3)
+
+Pattern uses Content-Addressable Records (CAR) format for portable agent backup and migration. Version 3 is designed for the SQLite-backed architecture with Loro CRDT memory.
+
+## Overview
+
+The export system supports three granularities:
+- **Agent**: Single agent with all data
+- **Group**: Group configuration plus member agents
+- **Constellation**: Full user constellation with deduplication
+
+Format features:
+- DAG-CBOR encoding for IPLD compatibility
+- Content-addressed blocks with CID references
+- Large data chunking (Loro snapshots, messages)
+- Streaming writes for memory efficiency
+- Letta/MemGPT .af file import support
+
+## Format Structure
+
+### Manifest (Root Block)
+
+Every CAR file starts with an `ExportManifest`:
+
+```rust
+pub struct ExportManifest {
+    pub version: u32,           // Currently 3
+    pub exported_at: DateTime<Utc>,
+    pub export_type: ExportType, // Agent, Group, or Constellation
+    pub stats: ExportStats,
+    pub data_cid: Cid,          // Points to AgentExport/GroupExport/ConstellationExport
+}
+```
+
+### Agent Export
+
+```rust
+pub struct AgentExport {
+    pub agent: AgentRecord,
+    pub message_chunk_cids: Vec<Cid>,
+    pub memory_block_cids: Vec<Cid>,
+    pub archival_entry_cids: Vec<Cid>,
+    pub archive_summary_cids: Vec<Cid>,
+}
+```
+
+### Group Export
+
+Two variants:
+- **Full**: Includes complete agent data
+- **Thin**: Configuration only, references existing agents by ID
+
+```rust
+// Full export
+pub struct GroupExport {
+    pub group: GroupRecord,
+    pub members: Vec<GroupMemberExport>,
+    pub agent_exports: Vec<AgentExport>,
+    pub shared_memory_cids: Vec<Cid>,
+    pub shared_attachment_exports: Vec<SharedBlockAttachmentExport>,
+}
+
+// Thin export (config only)
+pub struct GroupConfigExport {
+    pub group: GroupRecord,
+    pub member_agent_ids: Vec<String>,
+}
+```
+
+### Constellation Export
+
+```rust
+pub struct ConstellationExport {
+    pub version: u32,
+    pub owner_id: String,
+    pub exported_at: DateTime<Utc>,
+    pub agent_exports: HashMap<String, Cid>,  // Deduplicated pool
+    pub group_exports: Vec<GroupExportThin>,
+    pub standalone_agent_cids: Vec<Cid>,      // Agents not in any group
+    pub all_memory_block_cids: Vec<Cid>,
+    pub shared_attachments: Vec<SharedBlockAttachmentExport>,
+}
+```
+
+## Data Chunking
+
+### Message Chunks
+
+Messages are grouped into chunks based on size and count limits:
+
+```rust
+pub struct MessageChunk {
+    pub chunk_index: u32,
+    pub start_position: String,  // Snowflake ID
+    pub end_position: String,
+    pub messages: Vec<MessageExport>,
+    pub message_count: u32,
+}
+```
+
+Default limits:
+- `TARGET_CHUNK_BYTES`: 900KB (leaves headroom under 1MB block limit)
+- `DEFAULT_MAX_MESSAGES_PER_CHUNK`: 1000
+
+### Loro Snapshot Chunks
+
+Large Loro snapshots (>900KB) are split into linked chunks:
+
+```rust
+pub struct SnapshotChunk {
+    pub index: u32,
+    #[serde(with = "serde_bytes")]
+    pub data: Vec<u8>,
+    pub next_cid: Option<Cid>,  // Forward link
+}
+```
+
+Chunks are written in reverse order so each links forward, enabling streaming reconstruction.
+
+### Memory Block Export
+
+Memory blocks reference their snapshot chunks:
+
+```rust
+pub struct MemoryBlockExport {
+    pub id: String,
+    pub agent_id: String,
+    pub label: String,
+    pub block_type: MemoryBlockType,
+    pub permission: MemoryPermission,
+    // ... other metadata
+    pub snapshot_chunk_cids: Vec<Cid>,  // Links to chunks
+    pub total_snapshot_bytes: u64,
+}
+```
+
+## Usage
+
+### CLI Commands
+
+```bash
+# Export single agent
+pattern export agent my-agent
+pattern export agent my-agent -o backup.car
+
+# Export group with all member agents
+pattern export group my-group
+pattern export group my-group -o group.car
+
+# Export full constellation
+pattern export constellation
+pattern export constellation -o backup.car
+
+# Import from CAR file
+pattern import car backup.car
+
+# Import with rename
+pattern import car backup.car --rename-to NewAgentName
+
+# Import preserving original IDs (may conflict)
+pattern import car backup.car --preserve-ids
+
+# Convert and import Letta/MemGPT .af file
+pattern import letta agent.af
+pattern import letta agent.af -o converted.car
+```
+
+### Programmatic Usage
+
+```rust
+use pattern_core::export::{Exporter, ExportOptions, ExportTarget, ImportOptions, Importer};
+
+// Export an agent
+let exporter = Exporter::new(pool.clone());
+let mut output = File::create("agent.car").await?;
+let options = ExportOptions {
+    target: ExportTarget::Agent("agent-id".into()),
+    include_messages: true,
+    include_archival: true,
+    ..Default::default()
+};
+let manifest = exporter.export_agent("agent-id", &mut output, &options).await?;
+
+// Export a constellation
+let mut output = File::create("constellation.car").await?;
+let manifest = exporter.export_constellation("owner-id", &mut output, &options).await?;
+
+// Import
+let importer = Importer::new(pool.clone());
+let input = File::open("agent.car").await?;
+let options = ImportOptions::new("new-owner-id")
+    .with_rename("imported-agent")
+    .with_preserve_ids(false);
+let result = importer.import(input, &options).await?;
+```
+
+### Letta/MemGPT Import
+
+Convert and import Letta .af files:
+
+```rust
+use pattern_core::export::{convert_letta_to_car, LettaConversionOptions};
+
+// Convert to CAR format
+let options = LettaConversionOptions {
+    owner_id: "owner-id".into(),
+    preserve_timestamps: true,
+    ..Default::default()
+};
+let (car_data, stats) = convert_letta_to_car(&af_bytes, options)?;
+
+// Then import normally
+let importer = Importer::new(pool.clone());
+let result = importer.import(&car_data[..], &ImportOptions::new("owner-id")).await?;
+```
+
+## Export Options
+
+```rust
+pub struct ExportOptions {
+    pub target: ExportTarget,
+    pub include_messages: bool,      // Include message history
+    pub include_archival: bool,      // Include archival entries
+    pub max_chunk_bytes: usize,      // Max bytes per chunk
+    pub max_messages_per_chunk: usize,
+}
+```
+
+## Import Options
+
+```rust
+pub struct ImportOptions {
+    pub owner_id: String,            // New owner for imported data
+    pub rename: Option<String>,      // Rename the imported entity
+    pub preserve_ids: bool,          // Keep original IDs (may conflict)
+    pub include_messages: bool,      // Import message history
+    pub include_archival: bool,      // Import archival entries
+}
+```
+
+## Format Details
+
+### Block Encoding
+
+All blocks use DAG-CBOR (IPLD) encoding:
+- Deterministic serialization
+- CIDs computed from content hash
+- Maximum block size: 1MB
+
+```rust
+// Create CID from encoded data
+fn create_cid(data: &[u8]) -> Cid {
+    let hash = Code::Sha2_256.digest(data);
+    Cid::new_v1(DAG_CBOR, hash)
+}
+
+// Encode a block
+fn encode_block<T: Serialize>(value: &T, _type_name: &str) -> Result<(Cid, Vec<u8>)> {
+    let data = serde_ipld_dagcbor::to_vec(value)?;
+    let cid = create_cid(&data);
+    Ok((cid, data))
+}
+```
+
+### CAR File Structure
+
+```
+[CAR Header: version 1, root = manifest_cid]
+[manifest_cid → ExportManifest]
+[data_cid → AgentExport/GroupExport/ConstellationExport]
+[chunk_cids... → MessageChunk, SnapshotChunk, etc.]
+[entry_cids... → MemoryBlockExport, ArchivalEntryExport, etc.]
+```
+
+### Deduplication
+
+Constellation exports deduplicate agents across groups:
+- Each agent exported once
+- Groups reference agents by CID
+- Shared blocks exported once, referenced via attachments
+
+## Statistics
+
+Export stats track what was included:
+
+```rust
+pub struct ExportStats {
+    pub agent_count: u64,
+    pub group_count: u64,
+    pub message_count: u64,
+    pub memory_block_count: u64,
+    pub archival_entry_count: u64,
+    pub archive_summary_count: u64,
+    pub chunk_count: u64,
+    pub total_blocks: u64,
+    pub total_bytes: u64,
+}
+```
+
+## Migration from v2
+
+Key changes from v2:
+- SQLite-native: Works directly with pattern_db models
+- Loro integration: Properly chunks and reconstructs CRDT snapshots
+- Shared blocks: Exports block sharing relationships
+- Groups: Full group export with member agents
+- Constellation: Complete backup with deduplication
+
+## Legacy Docs
+
+Previous export format documentation is preserved in `docs/legacy/`:
+- `agent-export-design.md` - v2 design notes
+- `car-export-v2.md` - v2 format specification
+- `streaming-car-export.md` - Streaming design
+- `car-export-restructure-plan.md` - v2 to v3 migration plan

 # Pattern Memory Architecture & Multi-Agent Groups
 
-This document describes Pattern's memory hierarchy, agent coordination via Letta groups, and background processing strategies.
+This document describes Pattern's memory hierarchy, native agent coordination via groups, and background processing strategies.
 
 ## Memory Hierarchy
 
-Pattern uses a three-tier memory system optimized for ADHD cognitive support:
+Pattern uses a tiered memory system optimized for ADHD cognitive support:
 
-### 1. Immediate Access (Core Memory Blocks)
-Always visible in every agent's context window:
-- **current_state**: Real-time status (what's happening RIGHT NOW)
-- **active_context**: Recent important events and patterns
+### 1. Core Memory Blocks (Always in Context)
+Small blocks (~2000 chars each) always present in the agent's context window:
+- **persona**: Agent identity and capabilities
+- **current_state**: Real-time status (energy, attention, mood)
+- **active_context**: Current task and recent important events
 - **bond_evolution**: Relationship dynamics and trust building
 
-These blocks are small (~2000 tokens each) and frequently updated.
+### 2. Working Memory Blocks (Swappable)
+Active context that can be loaded or archived:
+- **Pinned blocks**: Always loaded when agent processes messages
+- **Ephemeral blocks**: Loaded only when referenced by notifications
 
-### 2. Searchable Knowledge (Letta Sources)
-Embedded documents accessible via semantic search:
-- Agent observations and insights
-- Partner behavior patterns over time
-- Cross-agent discoveries
-- Accumulated "learned wisdom"
+DataStream sources create Working blocks for their content:
+```rust
+// Source creates block for new content
+memory.create_block(
+    agent_id,
+    "discord_thread_12345",
+    "Discord thread context",
+    BlockType::Working,
+    BlockSchema::text(),
+    2000,
+).await?;
 
-Benefits:
-- No API calls for reading shared insights
-- Semantic search finds relevant patterns
-- Agents discover insights without coordination overhead
-- Creates persistent knowledge base
+// Block is included via batch_block_ids when processing notification
+let request = ContextBuilder::new(&memory, &config)
+    .for_agent(agent_id)
+    .with_batch_blocks(vec!["discord_thread_12345".to_string()])
+    .build()
+    .await?;
+```
 
-### 3. Deep Storage (Archival Memory)
-Full conversation history and specific moments:
-- Complete message history (via Letta's sliding window)
-- Important moments flagged for recall
-- Raw data for pattern analysis
-- Accessible via `archival_memory_search` tool
+### 3. Archival Memory (Searchable Long-term)
+Separate from blocks, searchable via FTS5 + sqlite-vec:
+- Agent observations and insights
+- Partner behaviour patterns over time
+- Accumulated wisdom
 
-## Context Window Management
+```rust
+// Store insight
+memory.insert_archival(
+    agent_id,
+    "User works best with time estimates multiplied by 1.5x",
+    Some(json!({"category": "time_patterns"})),
+).await?;
 
-Letta's context window structure:
+// Search later
+let results = memory.search_archival(agent_id, "time estimates", 10).await?;
 ```
-[ALWAYS PRESENT - Fixed overhead]
-1. System prompt
-2. Tool descriptions
-3. Summary (compressed older conversations)
-4. Core memory blocks
-5. Tool rules
 
-[SLIDING WINDOW - Dynamic]
-6. Recent messages (until token limit)
+### 4. Message History
+Conversation history with Snowflake ordering:
+- Complete message history with batching
+- Recursive summarization for context window management
+- FTS5 search across all messages
 
-[ACCESSIBLE VIA RECALL]
-7. Older messages (searchable but not in context)
-```
+## Memory Permissions
 
-Key insights:
-- We don't manually manage conversation history
-- Letta handles the sliding window automatically
-- Core memory must contain only critical real-time state
-- Archive agent compresses insights into summary

-### Why Groups Matter
-Instead of custom message routing, Letta's native groups API provides:
-- Unified conversation history across all agents
-- Multiple coordination strategies (dynamic, supervisor, round-robin)
-- Shared memory blocks between agents
-- Built-in sleeptime processing
+- `Partner` and `Human` permissions require approval via `PermissionBroker`
+- Requests appear as Discord/CLI notifications for humans to approve
 
-### Example Group Configurations
+## Block Schemas
 
-These are examples to illustrate the flexibility of groups - your implementation can define whatever groups make sense:
+Loro CRDT documents support typed schemas:
 
-#### Main Conversational Group
+**Text**: Simple text with optional viewport
 ```rust
-let main_group = client.groups().create(GroupCreate {
-    agent_ids: vec![pattern_id, entropy_id, flux_id, momentum_id, anchor_id, archive_id],
-    description: "Main ADHD support constellation".to_string(),
-    manager_config: Some(GroupCreateManagerConfig::Dynamic(DynamicManager {
-        manager_agent_id: pattern_id,
-        termination_token: Some("DONE!".to_string()),
-        max_turns: None,
-    })),
-    shared_block_ids: Some(vec![current_state_id, active_context_id, bond_evolution_id]),
-}).await?;
-```
-- **Purpose**: Normal partner interactions
-- **Manager**: Dynamic routing allows any agent to interject
-- **Use case**: "I'm feeling overwhelmed" → all agents see it, relevant ones respond
-
-#### Sleeptime Processing Group
+BlockSchema::Text { viewport: None }
+```
+
+**Map**: Structured key-value fields
 ```rust
-let sleeptime_group = client.groups().create(GroupCreate {
-    agent_ids: vec![pattern_id, archive_id],
-    description: "Memory consolidation team".to_string(),
-    manager_config: Some(GroupCreateManagerConfig::Sleeptime(SleeptimeManager {
-        manager_agent_id: archive_id,
-        sleeptime_agent_frequency: Some(20),  // every 20 messages
-    })),
-    shared_block_ids: Some(vec![current_state_id, active_context_id]),
-}).await?;
-```
-- **Purpose**: Background memory processing
-- **Manager**: Archive leads consolidation
-- **Use case**: Compress conversations, update shared insights
-
-#### Crisis Response Group
+BlockSchema::Map {
+    fields: vec![
+        FieldDef { name: "energy".into(), field_type: FieldType::Number, ..Default::default() },
+        FieldDef { name: "mood".into(), field_type: FieldType::Text, ..Default::default() },
+    ],
+}
+```
+
+**List**: Ordered collections (tasks, items)
 ```rust
-let crisis_group = client.groups().create(GroupCreate {
-    agent_ids: vec![pattern_id, momentum_id, anchor_id],
-    description: "Urgent intervention team".to_string(),
-    manager_config: Some(GroupCreateManagerConfig::RoundRobin(RoundRobinManager {
-        max_turns: Some(10),
-    })),
-    shared_block_ids: Some(vec![current_state_id]),
-}).await?;
-```
-- **Purpose**: Quick intervention for spiraling/crisis
-- **Manager**: Round-robin for rapid checks
-- **Use case**: "Help I'm spiraling" → quick focused response
-
-#### Planning Group
+BlockSchema::List { item_schema: None, max_items: Some(20) }
+```
+
+**Log**: Append-only with display limit
 ```rust
-let planning_group = client.groups().create(GroupCreate {
-    agent_ids: vec![entropy_id, flux_id, pattern_id],
-    description: "Task planning specialists".to_string(),
-    manager_config: Some(GroupCreateManagerConfig::Supervisor(SupervisorManager {
-        manager_agent_id: entropy_id,
-    })),
-    shared_block_ids: Some(vec![current_state_id, active_context_id]),
-}).await?;
-```
-- **Purpose**: Dedicated planning sessions
-- **Manager**: Entropy leads task breakdown
-- **Use case**: "Let's plan my day" → structured planning
-
-### Group Benefits
-- Same agents, different coordination styles
-- Overlapping groups for different contexts
-- Shared conversation history within groups
-- No manual message routing needed
-- **Completely flexible** - define groups that make sense for your use case
-
-## Overlapping Groups Architecture
-
-A key insight: since groups only reference existing agent IDs, we can create multiple overlapping groups with different configurations for different contexts.
-
-### Benefits of Overlapping Groups
-
-1. **Context-Specific Coordination**
-   - Normal conversation uses dynamic routing (anyone can jump in)
-   - Crisis moments use round-robin (quick systematic checks)
-   - Planning uses supervisor mode (Entropy leads structured breakdown)
-
-2. **Flexible Agent Participation**
-   - Not all agents needed for all contexts
-   - Crisis group: just Pattern, Momentum, Anchor (immediate needs)
-   - Planning group: just Entropy, Flux, Pattern (task/time focus)
-   - Sleeptime: just Pattern, Archive (memory processing)
-
-3. **Cost Optimization**
-   - Sleeptime groups can use cheaper models
-   - Crisis groups can use faster models
-   - Planning groups can use more analytical models
-
-### Example Usage Patterns
+BlockSchema::Log {
+    display_limit: 10,
+    entry_schema: LogEntrySchema { timestamp: true, agent_id: true, fields: vec![] },
+}
+```
 
+**Composite**: Multiple sections
 ```rust
-// Normal conversation
-let response = client.groups().send_message(
-    &main_group.id,
-    vec![MessageCreate::user("I'm feeling scattered today")]
-).await?;
-// All agents see it, dynamic routing determines who responds
-
-// Crisis intervention
-if detect_crisis(&message) {
-    let response = client.groups().send_message(
-        &crisis_group.id,
-        vec![MessageCreate::user("Help I'm spiraling")]
-    ).await?;
-    // Only Pattern, Momentum, Anchor respond with quick checks
+BlockSchema::Composite {
+    sections: vec![
+        CompositeSection { name: "notes".into(), schema: Box::new(BlockSchema::text()), read_only: false },
+        CompositeSection { name: "diagnostics".into(), schema: Box::new(BlockSchema::text()), read_only: true },
+    ],
 }
+```
+
+## Block Sharing
+
+Agents can share blocks with each other:
+```rust
+// Share a block with another agent (ReadOnly permission)
+db.share_block(owner_id, block_id, recipient_id, MemoryPermission::ReadOnly).await?;
+
+// Recipient sees it in their shared blocks
+let shared = memory.list_shared_blocks(recipient_id).await?;
+
+// Access shared content
+let doc = memory.get_shared_block(recipient_id, owner_id, "shared_notes").await?;
+```
 
-// Dedicated planning session
-if message.contains("plan") || message.contains("organize") {
-    let response = client.groups().send_message(
-        &planning_group.id,
-        vec![MessageCreate::user("Let's plan out my week")]
-    ).await?;
-    // Entropy leads, Flux provides time reality checks
+Shared blocks appear in context with attribution:
+```xml
+<block:shared_notes permission="ReadOnly" shared_from="Archive">
+Cross-agent insights about user patterns
+</block:shared_notes>
+```
+
+## Native Agent Groups
+
+Pattern's native coordination replaces external dependencies like Letta.
+
+### Constellations
+
+A constellation is a collection of agents for a specific user:
+```rust
+pub struct Constellation {
+    pub id: ConstellationId,
+    pub owner_id: UserId,
+    pub name: String,
+    pub agents: Vec<(AgentModel, ConstellationMembership)>,
+    pub groups: Vec<GroupId>,
 }
+```
 
-// Background processing (automatic)
-// Every 20 messages, sleeptime group activates
-// Archive processes conversation history with Pattern
+### Agent Groups
+
+Groups define how agents coordinate:
+```rust
+pub struct AgentGroup {
+    pub id: GroupId,
+    pub name: String,
+    pub description: String,
+    pub coordination_pattern: CoordinationPattern,
+    pub state: GroupState,
+    pub members: Vec<(AgentModel, GroupMembership)>,
+}
 ```
 
-### Group Selection Logic
+### Coordination Patterns
 
-The Discord bot or MCP server can intelligently route to appropriate groups:
+Six native coordination patterns:
 
+#### 1. Supervisor
+One agent leads, delegates to others:
 ```rust
-fn select_group(message: &str, user_state: &UserState) -> GroupId {
-    if is_crisis_language(message) || user_state.stress_level > 8 {
-        return crisis_group.id;
-    }
+CoordinationPattern::Supervisor {
+    leader_id: pattern_id,
+    delegation_rules: DelegationRules {
+        max_delegations_per_agent: Some(3),
+        delegation_strategy: DelegationStrategy::Capability,
+        fallback_behavior: FallbackBehavior::HandleSelf,
+    },
+}
+```
 
-    if is_planning_request(message) {
-        return planning_group.id;
-    }
+#### 2. Round Robin
+Agents take turns in order:
+```rust
+CoordinationPattern::RoundRobin {
+    current_index: 0,
+    skip_unavailable: true,
+}
+```
 
-    if is_memory_question(message) {
-        return memory_group.id;  // Archive-focused group
-    }
+#### 3. Voting
+Agents vote on decisions:
+```rust
+CoordinationPattern::Voting {
+    quorum: 3,
+    voting_rules: VotingRules {
+        voting_timeout: Duration::from_secs(30),
+        tie_breaker: TieBreaker::Random,
+        weight_by_expertise: true,
+    },
+}
+```
+
+#### 4. Pipeline
+Sequential processing through stages:
+```rust
+CoordinationPattern::Pipeline {
+    stages: vec![
+        PipelineStage {
+            name: "analysis".into(),
+            agent_ids: vec![entropy_id],
+            timeout: Duration::from_secs(60),
+            on_failure: StageFailureAction::Skip,
+        },
+        PipelineStage {
+            name: "scheduling".into(),
+            agent_ids: vec![flux_id],
+            timeout: Duration::from_secs(60),
+            on_failure: StageFailureAction::Retry { max_attempts: 2 },
+        },
+    ],
+    parallel_stages: false,
+}
+```
+
+#### 5. Dynamic
+Context-based agent selection:
+```rust
+CoordinationPattern::Dynamic {
+    selector_name: "capability".into(),
+    selector_config: HashMap::from([
+        ("preferred_domain".into(), "task_management".into()),
+    ]),
+}
+```
+
+Available selectors:
+- `random`: Random selection
+- `capability`: Match message content to agent capabilities
+- `load_balancing`: Select least recently used agent
+- `supervisor`: LLM-based selection by supervisor agent
 
-    // Default to main conversational group
-    main_group.id
+#### 6. Sleeptime
+Background monitoring with intervention triggers:
+```rust
+CoordinationPattern::Sleeptime {
+    check_interval: Duration::from_secs(20 * 60), // 20 minutes
+    triggers: vec![
+        SleeptimeTrigger {
+            name: "hyperfocus_check".into(),
+            condition: TriggerCondition::TimeElapsed {
+                duration: Duration::from_secs(90 * 60),
+            },
+            priority: TriggerPriority::High,
+        },
+        SleeptimeTrigger {
+            name: "constellation_sync".into(),
+            condition: TriggerCondition::ConstellationActivity {
+                message_threshold: 20,
+                time_threshold: Duration::from_secs(60 * 60),
+            },
+            priority: TriggerPriority::Medium,
+        },
+    ],
+    intervention_agent_id: Some(pattern_id),
 }
 ```
 
-### The Power of Flexibility
+### Group Member Roles
 
-The key insight is that groups are just references to existing agents. You can:
-- Create groups on the fly based on context
-- Experiment with different manager types
-- Add/remove agents from groups dynamically
-- Have one agent in many groups simultaneously
-- Create special-purpose groups for specific workflows
+```rust
+pub enum GroupMemberRole {
+    Regular,
+    Supervisor,
+    Observer,  // Receives messages but doesn't respond
+    Specialist { domain: String },
+}
+```
 
-This isn't a fixed architecture - it's a toolkit for building whatever coordination patterns emerge as useful.
+### Group Response Streaming
 
-## Custom Tiered Sleeptime Architecture
+Groups emit events during processing:
+```rust
+pub enum GroupResponseEvent {
+    Started { group_id, pattern, agent_count },
+    AgentStarted { agent_id, agent_name, role },
+    TextChunk { agent_id, text, is_final },
+    ToolCallStarted { agent_id, call_id, fn_name, args },
+    ToolCallCompleted { agent_id, call_id, result },
+    AgentCompleted { agent_id, agent_name, message_id },
+    Complete { group_id, pattern, execution_time, agent_responses, state_changes },
+    Error { agent_id, message, recoverable },
+}
+```
 
-Pattern also implements a custom tiered approach for cost optimization:
+## Example Group Configurations
 
-### Tier 1: Lightweight Monitor (Every 20min)
+### Main Conversational Group
 ```rust
-// Cheap rules-based or tiny model checks
-async fn quick_check() {
-    // Activity detection (are they at computer?)
-    // Time since last water/movement
-    // Current task duration
-
-    if concerning_pattern_detected() {
-        wake_pattern();  // Trigger expensive model
-    }
+AgentGroup {
+    name: "Main Support".into(),
+    coordination_pattern: CoordinationPattern::Dynamic {
+        selector_name: "capability".into(),
+        selector_config: HashMap::new(),
+    },
+    members: vec![pattern, entropy, flux, momentum, anchor, archive],
+}
+```
+
+### Crisis Response Group
+```rust
+AgentGroup {
+    name: "Crisis Response".into(),
+    coordination_pattern: CoordinationPattern::RoundRobin {
+        current_index: 0,
+        skip_unavailable: true,
+    },
+    members: vec![pattern, momentum, anchor],
 }
 ```
 
-**Triggers for waking Pattern:**
-- Hyperfocus >90min detected
-- No movement >2hrs
-- Task switch detected
-- User explicitly asks
+### Planning Session Group
+```rust
+AgentGroup {
+    name: "Planning".into(),
+    coordination_pattern: CoordinationPattern::Supervisor {
+        leader_id: entropy_id,
+        delegation_rules: DelegationRules::default(),
+    },
+    members: vec![entropy, flux, pattern],
+}
+```
 
-### Tier 2: Pattern Intervention (5-10x/day)
-When triggered, Pattern (expensive model) performs:
-- Comprehensive state assessment
-- Delegate to specialist agents
-- Update shared memory
-- Send Discord notifications if needed
+### Sleeptime Processing Group
+```rust
+AgentGroup {
+    name: "Memory Consolidation".into(),
+    coordination_pattern: CoordinationPattern::Sleeptime {
+        check_interval: Duration::from_secs(20 * 60),
+        triggers: vec![/* ... */],
+        intervention_agent_id: Some(archive_id),
+    },
+    members: vec![pattern, archive],
+}
+```
+
+## Overlapping Groups
+
+The same agent can belong to multiple groups with different coordination styles:
+
+```
+Pattern Agent
+├── Main Support (Dynamic)
+├── Crisis Response (RoundRobin)
+├── Planning (Supervisor - as member)
+└── Sleeptime (Sleeptime - as intervener)
+
+Entropy Agent
+├── Main Support (Dynamic)
+└── Planning (Supervisor - as leader)
+
+Archive Agent
+├── Main Support (Dynamic)
+└── Sleeptime (Sleeptime - as leader)
+```
 
-### Cost Optimization
-1. **Two-tier models**:
-   - Llama 3.1 8B for routine monitoring
-   - Claude/GPT-4 for complex interventions
-2. **Conditional awakening**: Pattern sleeps unless triggered
-3. **Batch processing**: Accumulate observations, process together
-4. **Shared context**: One expensive analysis, all agents read results
+Benefits:
+- Context-specific coordination styles
+- Cost optimization (simpler models for sleeptime)
+- Focused agent participation per context
+- Easy to experiment with different configurations
 
 ## Memory Processing Strategy
 
-### Hybrid Approach
-1. **Archive handles bulk processing**:
-   - Conversation summarization
-   - Cross-agent pattern detection
-   - Long-term memory consolidation
-   - Runs as sleeptime agent every ~20 conversations
+### Agent-Level Insights
+Each agent maintains domain-specific observations:
+```rust
+// Entropy observes task patterns
+memory.insert_archival(
+    entropy_id,
+    "Tasks labeled 'quick fix' average 3.2x estimated time",
+    Some(json!({"domain": "task_patterns"})),
+).await?;
+```
 
-2. **Specialists update domain insights**:
-   - Each agent maintains "learned_[domain]" memory block
-   - Updates after significant interactions
-   - Archive reads these for meta-patterns
+### Sleeptime Consolidation
+Archive agent processes accumulated insights during sleeptime:
+```rust
+// Sleeptime trigger fires
+// Archive reads recent observations from all agents
+let all_observations = memory.search_all("observations last 24h", options).await?;
+
+// Consolidates into meta-patterns
+memory.insert_archival(
+    archive_id,
+    "Cross-agent pattern: User productivity drops 40% after 2pm meetings",
+    Some(json!({"domain": "meta_patterns", "confidence": 0.85})),
+).await?;
 
-3. **Pattern performs meta-synthesis**:
-   - During sleeptime checks, reads all memory blocks
-   - Identifies cross-cutting concerns
-   - Updates strategic priorities
+// Updates shared blocks with key insights
+memory.update_block_text(
+    pattern_id,
+    "active_context",
+    "Note: Schedule creative work before meetings today",
+).await?;
+```
 
 ### Memory Flow
+
 ```
-Partner says something
+Partner interaction
     ↓
-Core memory (immediate context)
+Core memory updated (immediate context)
     ↓
-Agents process & observe
+Agent observes and processes
     ↓
-Write insights to sources (passive sharing)
+Insights stored to archival memory
     ↓
-Archive consolidates patterns (sleeptime)
+Sleeptime trigger fires
     ↓
-Updates core memory with key insights
+Archive consolidates patterns
+    ↓
+Key insights → shared blocks
+    ↓
+All agents see updated context
 ```
 
-## Passive Data Sharing via Sources
+## Cost Optimization
 
-Each agent can write observations to shared source files:
+### Two-Tier Model Strategy
+- **Routine monitoring**: Lightweight checks (rules-based or small model)
+- **Intervention**: Full model for complex interactions
 
+### Sleeptime Triggers
+Sleeptime patterns only invoke expensive models when triggers fire:
 ```rust
-// Agent tool for passive sharing
-fn write_to_shared_insights(category: &str, content: &str) {
-    // Writes to markdown file
-    // Automatically embedded by Letta
-    // Available to all agents via search_file
+TriggerCondition::ThresholdExceeded {
+    metric: "stress_level".into(),
+    threshold: 8.0,
 }
 ```
 
-### Example Source Files
-
-**sleeptime_observations.md**:
-```markdown
-[2025-07-04 14:30] Hyperfocus detected: coding session 2.5hrs
-[2025-07-04 14:30] Physical needs: last water 90min ago
-[2025-07-04 14:30] Energy state: flow but approaching burnout risk
+### Batch Processing
+Queue processing accumulates messages between expensive model calls:
+```rust
+let processor = QueueProcessor::new(config, runtime);
+processor.start(); // Polls queue, batches notifications
 ```
 
-**task_patterns.md** (by Entropy):
-```markdown
-- "quick fix" tasks average 3.2x estimated time
-- Morning tasks have 80% completion rate
-- Tasks with >5 subtasks rarely completed same day
-```
+## CLI Commands
+
+```bash
+# List groups
+pattern group list
+
+# Create group (interactive TUI builder)
+pattern group create
 
-**energy_patterns.md** (by Momentum):
-```markdown
-- Post-lunch dip consistent 2-4pm
-- Creative tasks best 10pm-2am
-- Meetings cost 2x recovery time on low-energy days
+# Add member
+pattern group add member "Planning" Flux --role specialist
+
+# View group status
+pattern group status "Planning"
+
+# Export group configuration
+pattern group export "Planning" -o planning.toml
 ```
 
-## Implementation Priority
+## Integration Points
 
-1. **Rebuild with new backends**
-2. **Implement shared source writing** (passive knowledge sharing)
-3. **Create overlapping group configurations** (context-specific coordination)
-4. **Build lightweight monitor** (tier 1 sleeptime)
-5. **Configure Archive as sleeptime processor** (memory consolidation)
+### Discord
+```rust
+// Route message to appropriate group
+let group_id = select_group(&message, &user_state);
+let events = group_manager.route_message(&group, &agents, message).await?;
+
+// Stream responses back to Discord
+while let Some(event) = events.next().await {
+    match event {
+        GroupResponseEvent::TextChunk { agent_id, text, .. } => {
+            discord.send_typing(&channel_id).await?;
+            discord.send_message(&channel_id, &text).await?;
+        }
+        // ...
+    }
+}
+```
 
-This architecture balances:
-- Continuous ADHD support
-- API cost efficiency
-- Shared knowledge between agents
-- Flexible coordination strategies
+### MCP Server
+Groups can be exposed as MCP tools:

+## Shared Memory Blocks
 
 All agents share these memory blocks for coordination without redundancy:
 
 ```rust
-// Shared state accessible by all agents
-pub struct SharedMemory {
-    // Real-time energy/attention/mood tracking (200 char limit)
-    current_state: Block,

 ### Agent Communication
 
 Agents coordinate through:
-- Shared memory updates (all agents see changes immediately)
-- `send_message_to_agent_async` for non-blocking coordination
+- Shared memory updates (all agents see changes via MemoryStore)
+- Message routing via AgentMessageRouter
 - Shared tools that any agent can invoke

 ## Data Architecture
 
-### Embedded Storage (No External Databases)
+### Embedded Storage (SQLite + Loro)
 
 All data stored locally using embedded databases:
 
 ```rust
-struct DataStore {
-    sqlite: SqlitePool,        // relational data
-    kv: sled::Db,             // key-value cache
-    vectors: hnsw::HNSW,      // vector similarity search
-}
-
-impl DataStore {
-    async fn new(path: &Path) -> Result<Self> {
-        // Everything in one directory
-        let sqlite = SqlitePool::connect(&format!("sqlite://{}/data.db", path)).await?;
-        let kv = sled::open(path.join("cache"))?;
-
-        // Build vector index from stored embeddings
-        let vectors = Self::load_or_create_index(&sqlite).await?;
-
-        Ok(Self { sqlite, kv, vectors })
-    }
-}
+// pattern_db provides SQLite storage
+use pattern_db::ConstellationDb;
+
+// Memory uses Loro CRDT for versioning
+use pattern_core::memory::{MemoryCache, MemoryStore};
+
+// Combined databases
+let dbs = ConstellationDatabases::open("./constellation.db", "./auth.db").await?;
+let memory = MemoryCache::new(dbs.clone());
 ```
 
 **SQLite** handles:
-- User data, agent configs
-- Calendar events and tasks
-- Stored embeddings (as blobs)
+- Agent configs and state
+- Messages and conversations
+- Memory block persistence
 - Full-text search via FTS5
 
-**Sled** provides:
-- Session cache
-- Activity state tracking
-- Rate limiting counters
-- Fast ephemeral data
+**Loro CRDT** provides:
+- Versioned memory blocks
+- Conflict-free merging
+- Time-travel for rollback
 
-**HNSW** enables:
+**sqlite-vec** enables:
+- 384-dimensional vector search
 - Semantic memory search
 - No external vector DB needed
-- Rebuilds from SQLite on startup
 
-Alternative: [sqlite-vss](https://github.com/asg017/sqlite-vss) extension for vectors directly in SQLite.
-
-### Memory Management
-
-Leverage Letta's 4-tier memory with local storage:
-- **Core**: Current context (2KB limit) - in-memory
-- **Archival**: SQLite + HNSW for unlimited storage with vector search
-- **Message**: Recent history in Sled cache
-- **Recall**: Semantic search via HNSW index
+### Memory Tiers
+- **Core**: Current context (configurable limit) - in Loro
+- **Working**: Short-term memory (configurable limit) - in Loro, loadable temporarily or pinnable in context
+- **Archival**: FTS5 + sqlite-vec for unlimited searchable storage
+- **Message**: Conversation history with summaries
+- **Embeddings**: Stored as blobs, indexed via sqlite-vec
 
 ### Built-in Agent Tools
 
-Pattern agents come with built-in tools for core functionality:
+Pattern agents come with built-in tools via BuiltinTools:
 
 ```rust
-// Tool registration happens automatically
-let builtin = BuiltinTools::default_for_agent(agent_handle);
+// Built-in tools are registered via the runtime
+let builtin = BuiltinTools::new(runtime.clone());
 builtin.register_all(&tool_registry);
 ```
 
 **Standard Tools**:
-- `update_memory`: Create/update persistent memory blocks
-- `send_message`: Send to users, agents, groups, or channels
-- `search_memory`: Semantic search across memory (planned)
-- `schedule_reminder`: Time-based reminders (planned)
+- `block`: Memory block operations (append, replace, archive, load, swap)
+- `recall`: Archival memory operations (insert, read, delete)
+- `search`: Unified search across memory and conversations
+- `send_message`: Route messages to users, agents, groups, or channels
 
 **Customization**:
+For a custom memory backend, implement `MemoryStore` and provide it to RuntimeContext:
+
 ```rust
-// Replace with custom implementations
-let builtin = BuiltinTools::builder()
-    .with_memory_tool(RedisMemoryTool::new(redis))
-    .build_for_agent(handle);
+let ctx = RuntimeContext::builder()
+    .dbs_owned(dbs)
+    .memory(Arc::new(CustomMemoryStore::new()))
+    .build()
+    .await?;
 ```
 
-**AgentHandle Architecture**:
-- Lightweight, cloneable access to agent internals
-- Separates cheap data (ID, memory) from expensive (messages)
-- Thread-safe with Arc<DashMap> for memory storage
+**AgentRuntime Architecture**:
+- Per-agent runtime with memory, tools, messages, routing
+- Tools access services through `ToolContext` trait
+- MemoryStore abstracts over storage implementation
+- Thread-safe with DashMap for concurrent access

-# Bluesky Cache & Deduplication Design
-
-## Goals
-
-1. **Reduce notification spam** - When multiple related posts arrive within seconds, send one comprehensive notification instead of many
-2. **Minimize API calls** - Cache thread context and post data to avoid redundant fetches
-3. **Preserve completeness** - Ensure notifications include full context even when batching
-
-## Current State
-
-### Already Implemented
-- **Batching Layer**: `PendingBatch` with DashMap collections for posts by thread/author
-- **Basic Cache Structure**: `thread_cache: Arc<DashMap<String, CachedThreadContext>>`
-- **TTL Fields**: `thread_cache_ttl: Duration` configured at 5 minutes
-- **Processing Tracking**: `processed_uris: DashMap<String, Instant>` for deduplication
-
-### Needs Implementation
-- **Cache utilization**: Thread cache exists but isn't being populated or checked
-- **Type conversions**: Ad-hoc `extract_*` functions need consolidation
-- **Embed improvements**: BlueskyPost uses raw atrium types for embeds
-- **Batch formatting**: Still sending individual posts instead of consolidated notifications
-
-## Type System Cleanup
-
-### Current Issues
-
-1. **BlueskyPost embed field**: Uses raw `Union<atrium_api::app::bsky::feed::post::RecordEmbedRefs>` 
-   - Should use our cleaner `EmbedInfo` enum instead
-   - Already have `extract_embed_info()` that produces it
-
-2. **Scattered conversion functions**:
-   - `extract_post_from_record()` - Converts RecordData to parts
-   - `extract_post_data()` - Extracts from PostView
-   - `extract_embed()` - Complex embed handling
-   - `extract_embed_info()` - Creates EmbedInfo from PostView
-   - `extract_record_embed()` - Handles RecordEmbedRefs
-   - `extract_image_alt_texts()` - Gets alt text from embeds
-   - `extract_post_relative_time()` - Formats time
-
-3. **Missing standard conversions**: No From/TryFrom impls for common conversions
-
-### Proposed BlueskyPost Improvements
-
-```rust
-pub struct BlueskyPost {
-    pub uri: String,
-    pub did: String,
-    pub cid: Cid,
-    pub handle: String,
-    pub display_name: Option<String>,
-    pub text: String,
-    pub created_at: DateTime<Utc>,
-    pub reply: Option<ReplyRef>,
-    pub embed: Option<EmbedInfo>,  // Changed from raw Union type
-    pub langs: Vec<String>,
-    pub labels: Vec<String>,
-    pub facets: Vec<Facet>,
-    // New fields for cache efficiency:
-    pub thread_root: Option<String>,  // Cached thread root
-    pub indexed_at: Option<DateTime<Utc>>,  // When Bluesky indexed it
-}
-
-impl BlueskyPost {
-    // Convert from firehose event (minimal data)
-    pub fn from_record(record: &RecordData, uri: &str, did: &str) -> Self { }
-    
-    // Convert from API response (full data)
-    pub fn from_post_view(post: &PostView) -> Self { }
-    
-    // Enrich minimal post with API data
-    pub async fn enrich(&mut self, post_view: &PostView) { }
-    
-    // Get thread root (compute if needed, cache result)
-    pub fn thread_root(&self) -> String { }
-}
-```
-
-## Cache Utilization
-
-### Existing Infrastructure
-
-```rust
-// Already in BlueskyFirehoseSource:
-pending_batch: Arc<PendingBatch>,  // Batching posts
-thread_cache: Arc<DashMap<String, CachedThreadContext>>,  // Ready to use
-thread_cache_ttl: Duration,  // 5 minute TTL
-
-// CachedThreadContext already defined:
-struct CachedThreadContext {
-    context: ThreadContext,  // Full thread with siblings, replies, engagement
-    cached_at: Instant,
-    thread_root: String,
-}
-```
-
-### What Needs Implementation
-
-1. **Populate cache on fetch**:
-   - When `build_thread_context()` fetches from constellation
-   - Store result in `thread_cache` with current Instant
-   
-2. **Check cache before fetch**:
-   - In `format_notification()`, check `thread_cache` first
-   - If exists and fresh (< 5 min), use cached context
-   - If stale or missing, fetch and update cache
-
-3. **Cache invalidation**:
-   - Check TTL on read: `if now - cached_at > thread_cache_ttl`
-   - Optional: Periodic cleanup task for expired entries
-
-### Cache Operations
-
-1. **On Jetstream Event Arrival**
-   ```
-   - Convert RecordData → basic BlueskyPost
-   - Check if thread_root exists in cache
-   - If cached and fresh: use it
-   - If not: add to batch for later fetch
-   ```
-
-2. **On Batch Flush**
-   ```
-   - Collect all unique thread_roots in batch
-   - Fetch missing contexts in parallel
-   - Cache all fetched data
-   - Build consolidated notification
-   ```
-
-3. **Cache Invalidation**
-   ```
-   - TTL expiration (5 min for threads, 10 min for posts)
-   - Manual invalidation on user actions
-   - Memory pressure limits
-   ```
-
-## Deduplication Strategy
-
-### Within Batch
-- Posts with same URI are merged (keep latest)
-- Multiple posts from same thread are grouped
-- Author's posts are kept in chronological order
-
-### Across Batches
-- Check `processed_uris` before creating notifications
-- Skip if recently processed (within 30 seconds)
-- But refresh cache if context is stale
-
-### Notification Consolidation
-
-For a batch containing multiple posts:
-
-```
-Thread: [root post]
-├─ @user1: "first reply"
-├─ @user2: "second reply"
-└─ @user1: "third reply"
-
-Becomes one notification:
-"Thread activity on [topic]:
- - user1 replied (2 messages)
- - user2 replied
- [Show full thread context]"
-```
-
-## Implementation Plan
-
-### Phase 1: Type System Cleanup ✨ Priority
-1. Change `BlueskyPost.embed` from raw Union to `Option<EmbedInfo>`
-2. Add `thread_root` and `indexed_at` fields to BlueskyPost
-3. Consolidate `extract_*` functions into BlueskyPost methods:
-   - `from_record()` - Create from firehose RecordData
-   - `from_post_view()` - Create from API PostView 
-   - `thread_root()` - Compute/cache thread root
-
-### Phase 2: Cache Integration 
-1. Modify `build_thread_context()` to populate `thread_cache`
-2. Update `format_notification()` to check cache before fetching
-3. Add TTL checking logic for cache entries
-
-### Phase 3: Batch Consolidation
-1. Enhance `format_batch_notification()` to actually consolidate posts
-2. Create thread summary from multiple posts in batch
-3. Aggregate engagement metrics across batch
-
-### Phase 4: Testing & Metrics
-1. Add tests for conversions and cache operations
-2. Add cache hit/miss logging
-3. Monitor API call reduction
-
-## Benefits
-
-1. **Performance**: 
-   - 70-90% reduction in constellation API calls
-   - Faster notification generation
-   - Lower memory usage from deduplication
-
-2. **User Experience**:
-   - Cleaner notifications (one per thread burst)
-   - More context in each notification
-   - Consistent thread views
-
-3. **System Health**:
-   - Reduced load on external APIs
-   - Better rate limit compliance
-   - More predictable resource usage
-
-## Risks & Mitigations
-
-1. **Stale Cache**: Mitigated by reasonable TTLs and refresh on important events
-2. **Memory Growth**: Bounded cache size with LRU eviction
-3. **Race Conditions**: DashMap handles concurrent access safely
-4. **Missing Context**: Fallback to direct fetch if cache miss

-                DateTime::from_timestamp_micros(c.time_us as i64).unwrap_or_default()
-            }),
-            error_count: self.stats.errors,

-                ("last_seq".to_string(), json!(self.stats.last_seq)),
-            ]),
-        }
-    }
-}
-```
-
-#### 1.5 Event Processing
-```rust
-fn handle_jetstream_event(
-    event: Event,
-    filter: &BlueskyFilter,
-) -> Option<Result<StreamEvent<BlueskyPost, BlueskyFirehoseCursor>>> {
-    // Extract post from commit if it matches filters
-    match event.kind {
-        Kind::Commit => {
-            if let Some(commit) = event.commit {
-                // Check if this is a post creation
-                if commit.collection == "app.bsky.feed.post" 
-                    && matches!(commit.operation, Operation::Create) {
-                    
-                    // Parse the post data
-                    if let Ok(post) = parse_bluesky_post(&commit, &event) {
-                        // Apply filters
-                        if should_include_post(&post, filter) {
-                            let cursor = BlueskyFirehoseCursor {
-                                seq: event.time_us, // Assuming this maps to seq
-                                time_us: event.time_us,
-                            };
-                            
-                            return Some(Ok(StreamEvent {
-                                item: post,
-                                cursor,
-                                timestamp: Utc::now(),
-                            }));
-                        }
-                    }
-                }
-            }
-        }
-        _ => {} // Handle other event types as needed
-    }
-    
-    None
-}
-
-fn parse_bluesky_post(commit: &Commit, event: &Event) -> Result<BlueskyPost> {
-    // Extract post data from commit record
-    // This will need to parse the actual ATProto record format
-    todo!("Parse commit.record into BlueskyPost")
-}
-
-fn should_include_post(post: &BlueskyPost, filter: &BlueskyFilter) -> bool {
-    // Apply all filters
-    
-    // DID filter
-    if !filter.dids.is_empty() && !filter.dids.contains(&post.did) {
-        return false;
-    }
-    
-    // Keyword filter
-    if !filter.keywords.is_empty() {
-        let text_lower = post.text.to_lowercase();
-        if !filter.keywords.iter().any(|kw| text_lower.contains(&kw.to_lowercase())) {
-            return false;
-        }
-    }
-    
-    // Language filter
-    if !filter.languages.is_empty() 
-        && !post.langs.iter().any(|lang| filter.languages.contains(lang)) {
-        return false;
-    }
-    
-    true
-}
-```
-
-### Phase 2: Prompt Templates for Bluesky
-
-Add specialized templates in `PromptTemplate::with_defaults()`:
-
-```rust
-// New post notification
-registry.register(
-    PromptTemplate::new(
-        "bluesky_post",
-        r#"New post from @{{ handle }} on Bluesky:
-{{ text }}
-
-[{{ uri }}]"#,
-    )?
-    .with_description("Bluesky post notification"),
-);
-
-// Reply notification
-registry.register(
-    PromptTemplate::new(
-        "bluesky_reply",
-        r#"@{{ handle }} replied to {{ reply_to }}:
-{{ text }}
-
-[{{ uri }}]"#,
-    )?
-    .with_description("Bluesky reply notification"),
-);
-
-// Mention notification
-registry.register(
-    PromptTemplate::new(
-        "bluesky_mention",
-        r#"You were mentioned by @{{ handle }}:
-{{ text }}
-
-[{{ uri }}]"#,
-    )?
-    .with_description("Bluesky mention notification"),
-);
-```
-
-### Phase 3: BlueskyEndpoint for Message Router
-
-#### Key Dependencies from Gork
-
-Based on the Gork implementation, we'll need:
-- `atrium-api` for proper type definitions (already have)
-- `bsky-sdk` for the BskyAgent posting interface
-- Proper OAuth/session handling
-
-```rust
-// From Gork's setup
-use bsky_sdk::BskyAgent;
-
-async fn setup_bsky_sess() -> anyhow::Result<BskyAgent> {
-    let agent = BskyAgent::builder().build().await?;
-    let res = agent
-        .login(std::env::var("ATP_USER")?, std::env::var("ATP_PASSWORD")?)
-        .await?;
-    Ok(agent)
-}
-
-// Creating a post with proper reply threading
-self.agent
-    .create_record(atrium_api::app::bsky::feed::post::RecordData {
-        created_at: Datetime::now(),
-        embed: None,
-        entities: None,
-        facets: None,
-        labels: None,
-        langs: None,
-        reply,  // This is the critical part!
-        tags: None,
-        text: "your text here".to_string(),
-    })
-    .await?;
-```
-
-#### 3.1 Endpoint Implementation
-```rust
-// pattern_core/src/context/message_router/endpoints/bluesky.rs
-
-use atrium_api::client::AtpClient;
-
-#[derive(Debug, Clone)]
-pub struct BlueskyEndpoint {
-    client: Arc<AtpClient>,
-    did: String,
-    handle: String,
-}
-
-#[async_trait]
-impl MessageEndpoint for BlueskyEndpoint {
-    fn endpoint_type(&self) -> &'static str {
-        "bluesky"
-    }
-
-    async fn send(
-        &self,
-        message: Message,
-        metadata: Option<serde_json::Value>,
-    ) -> Result<()> {
-        // Extract text from message
-        let text = extract_text_from_message(&message);
-        
-        // CRITICAL: Handle reply threading correctly
-        // Check metadata for reply_to information
-        let reply = if let Some(meta) = metadata {
-            if let Some(reply_to_uri) = meta.get("reply_to").and_then(|v| v.as_str()) {
-                // Parse the reply_to URI to extract CID
-                // Format: at://did/collection/rkey
-                
-                // For replies, MUST set BOTH parent and root
-                Some(ReplyRefData {
-                    parent: MainData {
-                        cid: reply_to_cid,
-                        uri: reply_to_uri.to_string(),
-                    },
-                    root: MainData {
-                        // If this is already a reply thread, get the original root
-                        // Otherwise, root = parent (first reply in thread)
-                        cid: root_cid,
-                        uri: root_uri,
-                    },
-                })
-            } else {
-                None
-            }
-        } else {
-            None
-        };
-        
-        // Create post using atrium-api
-        self.client
-            .create_record(CreateRecordInput {
-                collection: "app.bsky.feed.post".to_string(),
-                record: PostRecord {
-                    text,
-                    created_at: Utc::now(),
-                    reply,
-                    ..Default::default()
-                },
-            })
-            .await?;
-        
-        Ok(())
-    }
-
-    async fn receive(&self) -> Result<Option<Message>> {
-        // Could poll for mentions/replies
-        // But better to use firehose for real-time
-        Ok(None)
-    }
-}
-```
-
-#### ⚠️ CRITICAL: Reply Threading
-
-When implementing replies, you MUST set BOTH `parent` and `root` references:
-- `parent`: The immediate post being replied to
-- `root`: The original post that started the thread
-
-If replying to a non-reply post: `root = parent`
-If replying to a reply: `root = original thread starter` (NOT the parent!)
-
-**Common fuck-ups:**
-1. Only setting `parent` - breaks threading
-2. Setting `root = parent` when parent is already a reply - creates orphaned reply
-3. Not tracking the original root through the thread - loses context
-
-If you set root to the same as parent when there's an actual root up the chain, your reply appears as a reply to nothing. The thread breaks and users can't follow the conversation.
-
-#### 3.2 Tool Operation for Posting
-```rust
-// Add to DataSourceOperation enum
-PostToBluesky {
-    text: String,
-    reply_to: Option<String>,
-    embed: Option<serde_json::Value>,
-}
-
-// Handle in DataSourceTool::execute
-DataSourceOperation::PostToBluesky { text, reply_to, embed } => {
-    // Route through message router with BlueskyEndpoint
-    let target = MessageTarget {
-        target_type: TargetType::Channel,
-        target_id: Some("bluesky".to_string()),
-    };
-    
-    let message = Message::user(text);
-    
-    self.coordinator
-        .read()
-        .await
-        .agent_router
-        .send_message(target, message, embed)
-        .await?;
-    
-    Ok(DataSourceOutput {
-        success: true,
-        result: DataSourceResult::Success {
-            message: "Posted to Bluesky".to_string(),
-        },
-    })
-}
-```
-
-### Phase 4: Integration Example
-
-```rust
-// Setting up Bluesky monitoring for an agent
-let bluesky_source = BlueskyFirehoseSource::new(
-    "bluesky_mentions".to_string(),
-    JetstreamOptions::default()
-        .endpoint("wss://jetstream.atproto.tools/subscribe"),
-);
-
-// Filter for mentions of the agent
-let filter = BlueskyFilter {
-    nsids: vec!["app.bsky.feed.post".to_string()],
-    keywords: vec!["@myagent.bsky.social".to_string()],
-    ..Default::default()
-};
-
-// Add to coordinator
-coordinator.add_source(
-    bluesky_source.with_filter(filter),
-    BufferConfig {
-        max_items: 1000,
-        max_age: Duration::from_secs(3600),
-        persist_to_db: true,
-        index_content: false,
-    },
-    "bluesky_mention".to_string(),
-).await?;
-```
-
-## Testing Strategy
-
-1. **Unit Tests**
-   - Test filter logic
-   - Test cursor serialization/deserialization
-   - Test event parsing
-
-2. **Integration Tests**
-   - Mock rocketman connection
-   - Test full pipeline from event to agent notification
-
-3. **Live Testing**
-   - Create test account on Bluesky
-   - Monitor specific hashtags
-   - Test posting functionality
-
-## Dependencies Summary
-
-All dependencies ready:
-- `rocketman = "0.2.3"` - Jetstream consumer ✅
-- `atrium-api = "0.25.3"` - ATProto type definitions ✅
-- `bsky-sdk` - For BskyAgent and posting functionality ✅
-
-## Implementation Status ✅
-
-### Completed (2025-07-28)
-
-1. **BlueskyFirehoseSource** - Fully implemented with rocketman integration
-   - Custom `PostIngestor` implementing `LexiconIngestor` trait
-   - Proper WebSocket message handling with `handle_message`
-   - Cursor management for stream resumption
-   - Buffer support for historical data
-
-2. **Rich Text Support** - Facets for mentions, links, and hashtags
-   - `FacetFeature` enum with proper ATProto type tags
-   - Helper methods: `mentions()`, `mentioned_dids()`
-   - Byte slice indices for text annotations
-
-3. **Advanced Filtering** 
-   - Author DID filtering
-   - Keyword matching (case-insensitive)
-   - Language filtering
-   - **Mention whitelist** - Only process posts mentioning specific DIDs
-   - All filters properly tested
-
-4. **Event Parsing**
-   - Proper extraction from ATProto record format
-   - Support for all post fields: text, createdAt, facets, reply, embed, langs, labels
-   - Timestamp parsing from RFC3339 format
-   - URI construction: `at://did/collection/rkey`
-
-5. **Prompt Templates**
-   - `bluesky_post` - New post notifications
-   - `bluesky_reply` - Reply notifications
-   - `bluesky_mention` - Mention notifications
-
-### Still TODO
-
-1. **Test with live Jetstream connection** - Need to connect to actual firehose
-2. **Add BlueskyEndpoint for posting** - Implement message router endpoint (CRITICAL: handle reply threading correctly!)
-3. **Handle resolution** - Currently using DID as handle placeholder
-4. **Create example agent** - Build agent that monitors and responds to mentions
-5. **Parse embed content** - Extract alt text from images for accessibility, potentially image data for vision agents
-6. **Add rate limiting** - Prevent spam/abuse with per-DID cooldowns

-# Pattern Configuration System Design
+# Configuration System
 
-## Overview
-Configuration system for Pattern that allows persisting agent settings, user preferences, and system configuration across sessions.
+Pattern uses TOML configuration files to define agents, groups, memory blocks, data sources, and model settings. The system supports a cascade of configuration sources with runtime overrides.
 
-## Goals
-- Persist agent identity and configuration across sessions
-- User-friendly TOML format for manual editing
-- Layered configuration (defaults → file → CLI args)
-- Shared implementation between CLI and other consumers
-- Secure handling of sensitive data (API keys stay in env vars)
+## Configuration Files
 
-## Structure
+### Single-Agent Configuration (`pattern.toml`)
 
-### Core Config Types (in pattern-core)
+```toml
+[user]
+id = "user-id"        # Optional: auto-generated and persisted if not specified
+name = "Partner"
+
+[agent]
+name = "Assistant"
+persona_path = "persona.md"           # Path to persona file (relative to config)
+system_prompt_path = "instructions.md" # Path to system prompt file

+    pub members: Vec<GroupMemberConfig>,
+    pub shared_memory: HashMap<String, MemoryBlockConfig>,
+    pub data_sources: HashMap<String, DataSourceConfig>,
 }
 ```
 
-### Config Utilities (in pattern-core)
+## Coordination Pattern Configuration
 
-```rust
-// Load config from TOML file
-pub fn load_config(path: &Path) -> Result<PatternConfig>;
+Six patterns are supported:
 
-// Save config to TOML file
-pub fn save_config(config: &PatternConfig, path: &Path) -> Result<()>;
+### Supervisor
 
-// Merge configs with precedence
-pub fn merge_configs(base: PatternConfig, overlay: PartialConfig) -> PatternConfig;
+```toml
+[groups.pattern]
+type = "supervisor"
+leader = "Pattern"  # Member name who leads
+```
 
-// All configs implement Default
-impl Default for PatternConfig { ... }
+### Round Robin
+
+```toml
+[groups.pattern]
+type = "round_robin"
+skip_unavailable = true
 ```
 
-### CLI Usage
+### Pipeline
 
-1. **Config file locations** (checked in order):
-   - CLI argument: `--config path/to/config.toml`
-   - Project-specific: `./pattern.toml`
-   - User default: `~/.config/pattern/config.toml`
+```toml
+[groups.pattern]
+type = "pipeline"
+stages = ["Analysis", "Planning", "Execution"]
+```
 
-2. **Config layering**:
-   - Start with defaults
-   - Apply config file settings
-   - Override with CLI arguments
+### Dynamic
 
-3. **First run experience**:
-   - Generate user_id if not present
-   - Create default config
-   - Save to user config directory
+```toml
+[groups.pattern]
+type = "dynamic"
+selector = "capability"  # or "random", "load_balancing", "supervisor"
 
-## Example TOML File
+[groups.pattern.selector_config]
+preferred_domain = "task_management"
+```
+
+### Sleeptime

-## Implementation Steps
+## Tool Rules
+
+Control tool execution behavior:
+
+```toml
+# Continue loop after calling (default for most tools)
+[[agent.tool_rules]]
+tool_name = "search"
+rule_type = { type = "continue_loop" }
+
+# Exit loop after calling (ends agent's turn)
+[[agent.tool_rules]]

+
+# Must call first

+
+# Maximum calls per turn
+[[agent.tool_rules]]
+tool_name = "web_search"
+rule_type = { type = "max_calls", value = 3 }
+
+# Cooldown between calls (seconds)
+[[agent.tool_rules]]
+tool_name = "expensive_api"
+rule_type = { type = "cooldown", value = 30 }
+
+# Requires preceding tool
+[[agent.tool_rules]]
+tool_name = "submit"
+rule_type = { type = "requires_preceding_tools" }
+conditions = ["validate"]
+
+# Limit operations for multi-op tools
+[[agent.tool_rules]]
+tool_name = "block"
+rule_type = { type = "allowed_operations", value = ["append", "replace"] }
+
+# Requires user consent
+[[agent.tool_rules]]
+tool_name = "delete_file"
+rule_type = { type = "requires_consent", scope = "destructive_actions" }
+```
+
+## Context Configuration
+
+Override context building settings:
+
+```toml
+[agent.context]
+max_messages = 50
+memory_char_limit = 4000
+enable_thinking = true
+include_descriptions = true
+include_schemas = false
+activity_entries_limit = 10
+```
+
+## Configuration Cascade
+
+Configuration is resolved in priority order:
+
+1. **Runtime Overrides** (`AgentOverrides`) - Highest priority, not persisted
+2. **Agent Config** (from TOML or database)
+3. **Group Config** (for agents in groups)
+4. **PatternConfig defaults**
+
+```rust
+// Apply runtime overrides
+let resolved = ResolvedAgentConfig::from_agent_config(&agent_config, &defaults)
+    .apply_overrides(&AgentOverrides::new()
+        .with_model("openai", "gpt-4")
+        .with_temperature(0.7));
+```
+
+## Path Resolution
+
+Relative paths in configuration are resolved relative to the config file's directory:
+
+- `persona_path: "persona.md"` → `./persona.md`
+- `config_path: "agents/pattern/agent.toml"` → `./agents/pattern/agent.toml`
+- `content_path: "../shared/block.md"` → `../shared/block.md`
+
+## Loading Configuration
+
+```rust
+use pattern_core::config::{PatternConfig, load_config};
+
+// Load from standard locations (pattern.toml, ~/.config/pattern/config.toml, etc.)
+let config = PatternConfig::load().await?;
+
+// Load from specific file
+let config = PatternConfig::load_from(Path::new("./my-config.toml")).await?;
+
+// Load just agent config
+let agent_config = AgentConfig::load_from_file(Path::new("./agent.toml")).await?;
+
+// Save config
+config.save_to(Path::new("./pattern.toml")).await?;
+```
 
-1. Create config module in pattern-core
-2. Add serde derives to existing types that need serialization
-3. Implement config loading/saving with TOML
-4. Add config support to CLI with proper layering
-5. Update CLI to persist agent_id between sessions
-6. Add config validation and migration support
+## User ID Stability
 
-## Security Considerations
+The `user.id` is automatically generated and persisted to `~/.config/pattern/user_id` if not explicitly specified. This ensures the same user ID is used across sessions even without a config file.
 
-- API keys always come from environment variables, never stored in config
-- Config files should have appropriate permissions (user-readable only)
-- Sensitive data in memory blocks should be documented as such
+## Environment Variables
 
-## Future Extensions
+Sensitive credentials are stored in `auth.db`, not config files:
 
-- Config profiles (dev/prod/test)
-- Config validation schema
-- Migration between config versions
-- Encryption for sensitive memory blocks
+- Bluesky OAuth tokens and app passwords
+- Discord bot token (via `DISCORD_TOKEN` env var)
+- Model provider API keys (via standard env vars like `ANTHROPIC_API_KEY`)

+
+## Environment Variables
+
+Required environment variables (not in config files):
 
-Groups support three ways to configure members:
+```bash
+# Model providers (at least one required)
+export ANTHROPIC_API_KEY="sk-ant-..."
+export OPENAI_API_KEY="sk-..."
+export GEMINI_API_KEY="..."
 
-1. **Reference existing agent**: Use `agent_id` to reference an agent already in the database
-2. **External config file**: Use `config_path` to load agent configuration from a separate file
-3. **Inline configuration**: Define the agent configuration directly in the group member section
+# Discord (if using Discord integration)
+export DISCORD_TOKEN="..."
 
-See `pattern.example.toml` for examples of all three methods.
+# Bluesky credentials stored in auth.db via CLI
+# pattern atproto login your.handle.bsky.social

-# Data Sources Configuration Guide
+# Data Sources Guide
 
-This guide explains how to configure and use data sources with Pattern agents to enable them to monitor and respond to external data streams.
+Pattern's data source system enables agents to consume external data through two complementary traits: `DataStream` for real-time events and `DataBlock` for documents with version control.
 
 ## Overview
 
-Pattern's data source system allows agents to:
-- Monitor file systems for changes
-- Create indexed knowledge bases with semantic search
-- Connect to the Bluesky firehose for social media monitoring
-- Process data through customizable templates
-- Manage multiple sources simultaneously
+Data sources bridge external systems and agent memory. They:
+- Create and manage memory blocks for external content
+- Route notifications to agents or groups
+- Handle permission-gated edits with feedback
+- Support version history and rollback (for DataBlock)
 
-## Quick Start
+## Core Traits
 
-### 1. Simple File Monitoring
+### DataStream
 
-Monitor a directory and get notified when files change:
+For real-time event sources (Bluesky firehose, Discord, sensors):
 
 ```rust
-use pattern_core::data_source::monitor_directory;
-
-let coordinator = monitor_directory(
-    agent_id,
-    agent_name,
-    db,
-    "/path/to/watch",
-).await?;
+#[async_trait]
+pub trait DataStream: Send + Sync {
+    fn source_id(&self) -> &str;
+    fn name(&self) -> &str;
+    fn block_schemas(&self) -> Vec<BlockSchemaSpec>;
+    fn required_tools(&self) -> Vec<ToolRule>;
+
+    async fn start(&self, ctx: Arc<dyn ToolContext>, owner: AgentId)
+        -> Result<broadcast::Receiver<Notification>>;
+    async fn stop(&self) -> Result<()>;
+
+    fn pause(&self);
+    fn resume(&self);
+    fn status(&self) -> StreamStatus;
+
+    fn supports_pull(&self) -> bool;
+    async fn pull(&self, limit: usize, cursor: Option<StreamCursor>)
+        -> Result<Vec<Notification>>;
+}
 ```
 
-### 2. Indexed Knowledge Base
+### DataBlock
 
-Create a searchable knowledge base from documents:
+For document sources with versioning (files, configs):
 
 ```rust
-use pattern_core::data_source::create_knowledge_base;
-
-let coordinator = create_knowledge_base(
-    agent_id,
-    agent_name,
-    db,
-    "/path/to/documents",
-    embedding_provider,
-).await?;
+#[async_trait]
+pub trait DataBlock: Send + Sync {
+    fn source_id(&self) -> &str;
+    fn name(&self) -> &str;
+    fn block_schema(&self) -> BlockSchemaSpec;
+    fn permission_rules(&self) -> &[PermissionRule];
+    fn permission_for(&self, path: &Path) -> MemoryPermission;
+    fn matches(&self, path: &Path) -> bool;
+
+    async fn load(&self, path: &Path, ctx: Arc<dyn ToolContext>, owner: AgentId)
+        -> Result<BlockRef>;
+    async fn create(&self, path: &Path, content: Option<&str>, ctx, owner)
+        -> Result<BlockRef>;
+    async fn save(&self, block_ref: &BlockRef, ctx: Arc<dyn ToolContext>) -> Result<()>;
+    async fn delete(&self, path: &Path, ctx: Arc<dyn ToolContext>) -> Result<()>;
+
+    async fn start_watch(&self) -> Option<broadcast::Receiver<FileChange>>;
+    async fn stop_watch(&self) -> Result<()>;
+    fn status(&self) -> BlockSourceStatus;
+
+    async fn reconcile(&self, paths: &[PathBuf], ctx) -> Result<Vec<ReconcileResult>>;
+    async fn history(&self, block_ref: &BlockRef, ctx) -> Result<Vec<VersionInfo>>;
+    async fn rollback(&self, block_ref: &BlockRef, version: &str, ctx) -> Result<()>;
+    async fn diff(&self, block_ref, from: Option<&str>, to: Option<&str>, ctx) -> Result<String>;
+}
+```
 
-// Search the knowledge base
-let results = coordinator.search_source(
-    "file:/path/to/documents",
-    "search query",
-    10  // max results
-).await?;
+## Configuration
+
+### Bluesky Stream
+
+```toml
+[agent.data_sources.bluesky]
+type = "bluesky"
+name = "bluesky"
+target = "AgentName"  # or group name
+jetstream_endpoint = "wss://jetstream1.us-east.fire.hose.cam/subscribe"
+
+# Filtering
+friends = ["did:plc:friend1", "did:plc:friend2"]  # Always see posts from these
+keywords = ["adhd", "executive function"]          # Filter by keywords
+languages = ["en"]                                 # Filter by language
+exclude_dids = ["did:plc:spam"]                    # Block these users
+exclude_keywords = ["spam"]                        # Exclude these terms
+
+# Behavior
+allow_any_mentions = false          # Only friends can mention
+require_agent_participation = true  # Only show threads agent is in
 ```
 
-### 3. Bluesky Monitoring
+### File Source
+
+```toml
+[agent.data_sources.notes]
+type = "file"
+name = "notes"
+paths = ["./notes", "./documents"]
+recursive = true
+include_patterns = ["*.md", "*.txt"]
+exclude_patterns = ["*.tmp", ".git/**"]
+
+# Permission rules (evaluated in order)
+[[agent.data_sources.notes.permission_rules]]
+pattern = "*.config.toml"

+
+[[agent.data_sources.notes.permission_rules]]
+pattern = "notes/**/*.md"

-Monitor Bluesky for mentions and keywords:
+## Notification Routing
+
+Streams route notifications to agents or groups via the `target` field:
 
 ```rust
-use pattern_core::data_source::monitor_bluesky_mentions;
-
-let coordinator = monitor_bluesky_mentions(
-    agent_id,
-    agent_name,
-    db,
-    "your.handle",
-    Some(agent_handle),  // For enhanced notifications
-).await?;
+// Routing tries agent first, then group
+match router.route_message_to_agent(&target, message, origin).await {
+    Ok(Some(_)) => { /* routed to agent */ }
+    Ok(None) => {
+        // Agent not found, try as group

-## Advanced Configuration
+## SourceManager
 
-### Using the DataSourceBuilder
+Access source operations through `ToolContext::sources()`:
 
-For complex setups with multiple sources:
+```rust
+#[async_trait]
+pub trait SourceManager: Send + Sync {
+    // Stream operations
+    fn list_streams(&self) -> Vec<String>;
+    fn get_stream_info(&self, source_id: &str) -> Option<StreamSourceInfo>;
+    async fn pause_stream(&self, source_id: &str) -> Result<()>;
+    async fn resume_stream(&self, source_id: &str, ctx) -> Result<()>;
+    async fn subscribe_to_stream(&self, agent_id, source_id, ctx)
+        -> Result<broadcast::Receiver<Notification>>;
+    async fn pull_from_stream(&self, source_id, limit, cursor) -> Result<Vec<Notification>>;
+
+    // Block operations
+    fn list_block_sources(&self) -> Vec<String>;
+    fn get_block_source_info(&self, source_id: &str) -> Option<BlockSourceInfo>;
+    async fn load_block(&self, source_id, path, owner) -> Result<BlockRef>;
+    async fn create_block(&self, source_id, path, content, owner) -> Result<BlockRef>;
+    async fn save_block(&self, source_id, block_ref) -> Result<()>;
+    async fn delete_block(&self, source_id, path) -> Result<()>;
+    fn find_block_source_for_path(&self, path: &Path) -> Option<Arc<dyn DataBlock>>;
+
+    // Version control
+    async fn reconcile_blocks(&self, source_id, paths) -> Result<Vec<ReconcileResult>>;
+    async fn block_history(&self, source_id, block_ref) -> Result<Vec<VersionInfo>>;
+    async fn rollback_block(&self, source_id, block_ref, version) -> Result<()>;
+    async fn diff_block(&self, source_id, block_ref, from, to) -> Result<String>;
+
+    // Edit routing
+    async fn handle_block_edit(&self, edit: &BlockEdit) -> Result<EditFeedback>;
+}
+```
+
+## Helper Utilities
+
+### BlockBuilder
+
+Fluent block creation:
 
 ```rust
-use pattern_core::data_source::{DataSourceBuilder, BlueskyFilter};
-
-let coordinator = DataSourceBuilder::new()
-    // Add file sources
-    .with_file_source("/data/static", false, true)      // indexed
-    .with_file_source("/data/inbox", true, false)       // watched
-    .with_templated_file_source(
-        "/data/reports",
-        "/templates/report.j2",
-        true,
-        false
-    )
-    // Add Bluesky sources
-    .with_bluesky_source(
-        "social_monitor".to_string(),
-        BlueskyFilter {
-            mentions: vec!["pattern.bsky.social".to_string()],
-            keywords: vec!["ADHD".to_string()],
-            languages: vec!["en".to_string()],
-            ..Default::default()
-        },
-        true  // use agent handle
-    )
-    .build(
-        agent_id,
-        agent_name,
-        db,
-        Some(embedding_provider),
-        Some(agent_handle),
-    )
+use pattern_core::data_source::BlockBuilder;
+
+let block_ref = BlockBuilder::new(memory, owner, "user_profile")
+    .description("User profile information")
+    .schema(BlockSchema::Text { viewport: None })
+    .pinned()  // Always in context
+    .content("Initial content")
+    .build()
     .await?;
 ```
 
-### Bluesky Filters
+### NotificationBuilder
 
-Configure what content to monitor:
+Build notifications with blocks:
 
 ```rust
-BlueskyFilter {
-    // AT Protocol NSIDs to monitor
-    nsids: vec!["app.bsky.feed.post".to_string()],
-    
-    // Handles to watch for mentions
-    mentions: vec!["alice.bsky.social".to_string()],
-    
-    // DIDs to follow
-    dids: vec!["did:plc:abc123...".to_string()],
-    
-    // Keywords to match
-    keywords: vec!["ADHD".to_string(), "executive function".to_string()],
-    
-    // Language codes
-    languages: vec!["en".to_string(), "es".to_string()],
-}
+use pattern_core::data_source::NotificationBuilder;
+
+let notification = NotificationBuilder::new("bluesky")
+    .text("New post from @alice about ADHD strategies")
+    .priority(NotificationPriority::Normal)
+    .block(context_block_ref)
+    .block(thread_block_ref)
+    .build();
 ```
 
-## Managing Data Sources
+### EphemeralBlockCache
 
-### Source Operations
+Get-or-create cache for ephemeral blocks:
 
 ```rust
-// List all sources
-let sources = coordinator.list_sources().await;
-for (id, source_type) in sources {
-    println!("{}: {}", id, source_type);
-}
-
-// Read from a source
-let items = coordinator.read_source(
-    "file:/data/inbox",
-    10,      // limit
-    None     // cursor
+let cache = EphemeralBlockCache::new();
+
+// Returns existing block or creates new one
+let block_ref = cache.get_or_create(
+    "did:plc:user123",  // External ID
+    || async {
+        BlockBuilder::new(memory, owner, "user_context")
+            .ephemeral()
+            .build()
+            .await
+    }
 ).await?;
+```
 
-// Search within a source
-let results = coordinator.search_source(
-    "file:/data/knowledge",
-    "executive function strategies",
-    5
-).await?;
+## Edit Feedback
 
-// Pause/resume monitoring
-coordinator.pause_source("bluesky_monitor").await?;
-coordinator.resume_source("bluesky_monitor").await?;
+Sources can approve, defer, or reject edits:
 
-// Get buffer statistics
-let stats = coordinator.get_buffer_stats("file:/data/inbox").await?;
+```rust
+pub enum EditFeedback {
+    Applied { message: Option<String> },  // Edit was applied
+    Pending { message: Option<String> },  // Async operation pending
+    Rejected { reason: String },          // Edit rejected
+}
 ```
 
-### Dynamic Source Management
-
-Add sources at runtime:
+Example handler:
 
 ```rust
-use pattern_core::data_source::{add_file_source, add_bluesky_source};
-
-// Add a file source
-add_file_source(
-    &mut coordinator,
-    "/new/path",
-    true,    // watch
-    false,   // indexed
-    None     // template
-).await?;
+async fn handle_block_edit(&self, edit: &BlockEdit, ctx: Arc<dyn ToolContext>)
+    -> Result<EditFeedback>
+{
+    let permission = self.permission_for(Path::new(&edit.block_label));
+
+    match permission {
+        MemoryPermission::ReadOnly => {
+            Ok(EditFeedback::Rejected {
+                reason: "File is read-only".to_string()
+            })
+        }
+        MemoryPermission::ReadWrite => {
+            // Apply edit to disk
+            self.save_to_disk(edit).await?;
+            Ok(EditFeedback::Applied { message: None })
+        }
+        _ => Ok(EditFeedback::Applied { message: None })
+    }
+}
+```
+
+## File Source Sync Model
 
-// Add a Bluesky source
-add_bluesky_source(
-    &mut coordinator,
-    "new_monitor".to_string(),
-    None,    // default endpoint
-    filter,
-    agent_handle
-).await?;
+```
+Agent tools <-> Loro CRDT <-> Disk <-> External Editor
+                    ^
+               Version history
 ```
 
-## Integration with Agents
+- **Loro as working state**: Agent's view with full version history
+- **Disk as canonical**: External changes detected via watch/reconcile
+- **Permission-gated writes**: Glob patterns determine access levels
 
-### Agent Handle for Enhanced Notifications
+### Reconciliation
 
-When you provide an agent handle to data sources, they can:
-- Access agent memory for context
-- Create memory blocks for tracked entities
-- Fetch additional context (e.g., Bluesky thread history)
-- Provide richer notifications to the agent
+After external file changes:
 
 ```rust
-let agent_handle = agent.memory();
-
-// Bluesky source with handle can fetch thread context
-let coordinator = monitor_bluesky_mentions(
-    agent_id,
-    agent_name,
-    db,
-    handle,
-    Some(agent_handle),  // Enhanced features enabled
-).await?;
+let results = source_manager.reconcile_blocks("files", &changed_paths).await?;
+
+for result in results {
+    match result {
+        ReconcileResult::Resolved { path, resolution } => {
+            println!("{}: {:?}", path, resolution);
+        }
+        ReconcileResult::NeedsResolution { path, disk_changes, agent_changes } => {
+            // Present conflict to user
+        }
+        ReconcileResult::NoChange { path } => {}
+    }
+}
 ```
 
-### Data Flow
+Resolution strategies:
+- `DiskWins`: External changes overwrite
+- `AgentWins`: Agent's Loro changes preserved
+- `Merge`: CRDT merge applied
+- `Conflict`: Needs human decision
 
-1. **Source Detection**: Data sources monitor for new items
-2. **Template Processing**: Items are formatted using Jinja2 templates
-3. **Agent Notification**: Formatted messages sent to agent
-4. **Agent Response**: Agent processes and potentially responds
-5. **Memory Update**: Important information stored in agent memory
+## BlueskyStream Features
 
-## File Storage Modes
+- **Jetstream consumption**: Real-time WebSocket firehose
+- **DID/keyword/language filtering**: Reduce noise
+- **Friend list**: Always see posts from specific DIDs
+- **Thread context**: Fetches parent posts from constellation API
+- **Post batching**: 20-second windows to reduce notification frequency
+- **Agent participation**: Only show threads agent has engaged in
+- **Rich text parsing**: Extracts mentions and links
 
-### Ephemeral Mode
-- Default for watched directories
-- Items processed and discarded
-- No indexing or search capability
-- Low memory overhead
+## Programmatic Usage
 
-### Indexed Mode
-- Requires embedding provider
-- Documents chunked and embedded
-- Full semantic search support
-- Higher memory/compute requirements
+### Creating Sources from Config
 
 ```rust
-// Ephemeral - good for transient data
-.with_file_source("/tmp/uploads", true, false)
+use pattern_core::config::DataSourceConfig;
 
-// Indexed - good for knowledge bases
-.with_file_source("/data/docs", false, true)
-```
+// Create from configuration
+let blocks = config.create_blocks(dbs.clone()).await?;
+let streams = config.create_streams(dbs.clone(), tool_context.clone()).await?;
 
-## Template System
+// Register with runtime
+for block in blocks {
+    runtime.register_block_source(block);
+}
+for stream in streams {
+    runtime.register_stream_source(stream);
+}
+```
 
-Templates control how data is presented to agents:
+### Manual Source Creation
 
-```jinja2
-{# /templates/bluesky_post.j2 #}
-New post from @{{ author_handle }}:
+```rust
+use pattern_core::data_source::{BlueskyStream, FileSource};
 
-{{ post_text }}
+// Bluesky stream
+let stream = BlueskyStream::new("bluesky", tool_context.clone())
+    .with_agent_did(did.clone())
+    .with_authenticated_agent(agent.clone())
+    .with_config(config.clone());
 
-{% if is_reply %}
-In reply to: {{ parent_author }}
-{% endif %}
+let rx = stream.start(ctx.clone(), owner).await?;
 
-{% if mentions %}
-Mentions: {{ mentions | join(", ") }}
-{% endif %}
+// File source
+let source = FileSource::from_config(base_path, &file_config);
+let block_ref = source.load(&file_path, ctx.clone(), owner).await?;
 ```
 
-## Performance Considerations
+## Implementation Patterns
 
-1. **Buffer Configuration**
-   - Adjust buffer sizes based on data volume
-   - Monitor buffer stats to detect backpressure
-   - Use pagination for large result sets
+### Accessing Sources from Tools (as_any downcast)
 
-2. **Indexing Strategy**
-   - Only index stable, searchable content
-   - Use ephemeral mode for transient data
-   - Balance chunk size vs search granularity
+Tools that need typed access to specific data sources should use the `as_any()` downcast pattern. This allows tools to be created uniformly via `create_builtin_tool()` while still accessing type-specific source methods at runtime.
 
-3. **Notification Frequency**
-   - Batch related items when possible
-   - Use rate limiting for high-volume sources
-   - Consider agent processing capacity
+```rust
+use std::any::Any;
 
-## Troubleshooting
+// DataStream trait includes as_any() for downcasting
+pub trait DataStream: Send + Sync {
+    fn as_any(&self) -> &dyn Any;
+    // ... other methods
+}
 
-### Common Issues
+// Tool implementation
+pub struct ShellTool {
+    ctx: Arc<dyn ToolContext>,
+    source_id: Option<String>,  // Optional explicit target
+}
 
-1. **"No embedding provider" warning**
-   - Indexed mode requires embedding provider
-   - Falls back to ephemeral automatically
-   - Provide embeddings for search capability
+impl ShellTool {
+    /// Get SourceManager from ToolContext.
+    fn sources(&self) -> Result<Arc<dyn SourceManager>> {
+        self.ctx.sources().ok_or_else(|| {
+            CoreError::tool_exec_msg("shell", "no source manager available")
+        })
+    }
+
+    /// Find ProcessSource by ID or default.
+    fn find_process_source(&self, sources: &dyn SourceManager)
+        -> Result<Arc<dyn DataStream>>
+    {
+        // Try explicit source_id first
+        if let Some(id) = &self.source_id {
+            if let Some(source) = sources.get_stream_source(id) {
+                return Ok(source);
+            }
+        }
+
+        // Try default ID
+        if let Some(source) = sources.get_stream_source("process:shell") {
+            return Ok(source);
+        }
+
+        // Find first ProcessSource
+        for id in sources.list_streams() {
+            if let Some(source) = sources.get_stream_source(&id) {
+                if source.as_any().is::<ProcessSource>() {
+                    return Ok(source);
+                }
+            }
+        }
+
+        Err(CoreError::tool_exec_msg("shell", "no process source found"))
+    }
+
+    /// Downcast to concrete ProcessSource.
+    fn as_process_source(source: &dyn DataStream) -> Result<&ProcessSource> {
+        source.as_any().downcast_ref::<ProcessSource>().ok_or_else(|| {
+            CoreError::tool_exec_msg("shell", "source is not a ProcessSource")
+        })
+    }
+}
+```
 
-2. **Buffer overflow**
-   - Check buffer stats regularly
-   - Increase buffer size if needed
-   - Consider sampling high-volume streams
+**Key points:**
+- Store `Arc<dyn ToolContext>`, not the concrete source
+- Implement `as_any()` on all `DataStream` implementations
+- Use fallback chain: explicit ID → default ID → first matching type
+- Downcast at point of use, not at construction
 
-3. **Template errors**
-   - Validate Jinja2 syntax
-   - Ensure all variables are available
-   - Check template file permissions
+### Notification Routing Task Pattern
 
-### Debug Commands
+DataStream implementations that emit notifications should spawn a routing task to forward them to the owner agent. This pattern is used by BlueskyStream and ProcessSource.
 
 ```rust
-// Check source status
-let sources = coordinator.list_sources().await;
-
-// Monitor buffer health
-let stats = coordinator.get_buffer_stats(source_id).await?;
-println!("Buffered: {}, Dropped: {}", 
-    stats["buffered_count"], 
-    stats["dropped_count"]
-);
-
-// Test source connectivity
-let test_items = coordinator.read_source(source_id, 1, None).await?;
+impl ProcessSource {
+    async fn start(&self, ctx: Arc<dyn ToolContext>, owner: AgentId)
+        -> Result<broadcast::Receiver<Notification>>
+    {
+        // Create broadcast channel
+        let (tx, rx) = broadcast::channel(256);
+        *self.tx.write() = Some(tx.clone());
+
+        // Store context and owner for later use
+        *self.ctx.write() = Some(ctx.clone());
+        *self.owner.write() = Some(owner.to_string());
+
+        // Spawn routing task
+        let routing_rx = tx.subscribe();
+        let owner_id = owner.to_string();
+        let source_id = self.source_id().to_string();
+
+        tokio::spawn(async move {
+            route_notifications(routing_rx, owner_id, source_id, ctx).await;
+        });
+
+        *self.status.write() = StreamStatus::Running;
+        Ok(rx)
+    }
+}
+
+/// Route notifications from source to owner agent.
+async fn route_notifications(
+    mut rx: broadcast::Receiver<Notification>,
+    owner_id: String,
+    source_id: String,
+    ctx: Arc<dyn ToolContext>,
+) {
+    let router = ctx.router();
+
+    loop {
+        match rx.recv().await {
+            Ok(notification) => {
+                let mut message = notification.message;
+                message.batch = Some(notification.batch_id);
+
+                // Extract origin from message metadata for routing context
+                let origin = message.metadata.custom.as_object().and_then(|obj| {
+                    serde_json::from_value::<MessageOrigin>(
+                        serde_json::Value::Object(obj.clone())
+                    ).ok()
+                });
+
+                // Route to owner agent
+                match router.route_message_to_agent(&owner_id, message, origin).await {
+                    Ok(Some(_)) => {
+                        debug!(source_id = %source_id, "routed notification to owner");
+                    }
+                    Ok(None) => {
+                        warn!(source_id = %source_id, "owner agent not found");
+                    }
+                    Err(e) => {
+                        warn!(source_id = %source_id, error = %e, "routing failed");
+                    }
+                }
+            }
+            Err(broadcast::error::RecvError::Lagged(n)) => {
+                warn!(source_id = %source_id, lagged = n, "notification routing lagged");
+            }
+            Err(broadcast::error::RecvError::Closed) => {
+                info!(source_id = %source_id, "channel closed, stopping routing");
+                break;
+            }
+        }
+    }
+}
 ```
 
+**Key points:**
+- Spawn routing task in `start()`, not constructor
+- Use `ctx.router()` for message routing
+- Store `MessageOrigin` in message metadata for routing context
+- Handle `Lagged` (log warning) and `Closed` (exit loop) errors
+- Set `message.batch` from notification's `batch_id`
+
 ## Best Practices
 
-1. **Start Simple**: Begin with basic file monitoring, add complexity gradually
-2. **Monitor Performance**: Track buffer stats and processing times
-3. **Use Templates**: Keep agent prompts consistent and maintainable
-4. **Index Wisely**: Only index content that needs semantic search
-5. **Handle Errors**: Implement retry logic for network sources
-6. **Test Locally**: Use file sources to prototype before connecting to live streams
+### Source Type Selection
+
+| Source Type | Use For |
+|-------------|---------|
+| DataStream | Real-time events, social media, sensors |
+| DataBlock | Documents, configs, files needing version control |
+
+### Performance
 
-## Example Use Cases
+- **Batching**: BlueskyStream batches posts (20s windows) to reduce agent invocations
+- **Ephemeral blocks**: Use for transient context, drops from memory after batch
+- **Pinned blocks**: Reserve for always-needed state (user config, agent settings)
 
-### ADHD Task Inbox
-Monitor a directory where users drop task files, automatically parsing and organizing them.
+### Permission Rules
 
-### Knowledge Management
-Index documentation and notes for instant retrieval during conversations.
+Define from most to least restrictive:
 
-### Social Media Support
-Monitor mentions to provide timely ADHD support on Bluesky.
+```toml
+# Config files: read-only
+[[agent.data_sources.files.permission_rules]]
+pattern = "**/*.config.toml"
+permission = "read_only"
 
-### Multi-Modal Pipeline
-Combine file monitoring, knowledge base, and social media for comprehensive support.
\ No newline at end of file
+# Sensitive files: require escalation
+[[agent.data_sources.files.permission_rules]]
+pattern = "**/secrets/**"
+permission = "human"
+
+# General notes: full access
+[[agent.data_sources.files.permission_rules]]
+pattern = "notes/**/*.md"
+permission = "read_write"
+```
+
+### Error Handling
+
+```rust
+match source_manager.load_block("files", &path, owner).await {
+    Ok(block_ref) => {
+        // Use block_ref.block_id with memory operations
+    }
+    Err(e) if e.is_not_found() => {
+        // File doesn't exist, offer to create
+    }
+    Err(e) if e.is_permission_denied() => {
+        // Path not covered by permission rules
+    }
+    Err(e) => return Err(e),
+}
+```

-# Data Sources for Pattern Agents
+# Data Sources
 
-This document describes the data source abstraction system that allows Pattern agents to consume data from various sources including files, streams, and APIs.
+Pattern's data source system enables agents to consume data from external sources like files, social media, and APIs. It uses two core traits: `DataStream` for event-driven sources and `DataBlock` for document-oriented sources.
 
-## Overview
+## Architecture
 
-The data source system provides a flexible way to pipe inputs from various data sources to prompt agents. It supports both pull-based (polling) and push-based (streaming) data consumption patterns with proper cursor management for resumption.
+### Core Traits
 
-## Architecture
+#### DataStream
 
-### Core Components
+For real-time event sources (Bluesky firehose, Discord events):
 
-1. **DataSource Trait** (`pattern_core/src/data_source/traits.rs`)
-   - Generic trait with associated types for Item, Filter, and Cursor
-   - Supports both `pull()` for polling and `subscribe()` for streaming
-   - Metadata tracking for source status and statistics
+```rust
+#[async_trait]
+pub trait DataStream: Send + Sync + std::fmt::Debug {
+    /// Unique identifier for this source
+    fn source_id(&self) -> &str;
 
-2. **DataIngestionCoordinator** (`pattern_core/src/data_source/coordinator.rs`)
-   - Manages multiple data sources
-   - Routes data to agents via prompt templates
-   - Type-erased wrapper pattern for generic handling
-   - Integrates with agent's embedding provider
+    /// Human-readable name
+    fn name(&self) -> &str;
 
-3. **FileDataSource** (`pattern_core/src/data_source/file.rs`)
-   - Concrete implementation for file-based data
-   - Two storage modes:
-     - **Ephemeral**: Simple file monitoring without persistence
-     - **Indexed**: Semantic search with embeddings
-   - Watch support for file change notifications
-   - Multiple cursor types (ModTime, LineNumber, ByteOffset)
+    /// Memory block schemas this source may create
+    fn block_schemas(&self) -> Vec<BlockSchemaSpec>;
 
-4. **StreamBuffer** (`pattern_core/src/data_source/buffer.rs`)
-   - Caches stream data with configurable limits
-   - Time-based and count-based retention
-   - Optional database persistence for historical search
+    /// Tool rules required when this source is active
+    fn required_tools(&self) -> Vec<ToolRule>;
 
-5. **PromptTemplate** (`pattern_core/src/prompt_template.rs`)
-   - Jinja2-style templates using minijinja
-   - Default templates for common data sources
-   - Variable extraction and validation
+    /// Start the stream and return a notification receiver
+    async fn start(
+        &self,
+        ctx: Arc<dyn ToolContext>,
+        owner: AgentId,
+    ) -> Result<broadcast::Receiver<Notification>>;
 
-6. **DataSourceTool** (`pattern_core/src/tool/builtin/data_source.rs`)
-   - Agent-accessible tool for data source operations
-   - Operations: ReadFile, IndexFile, WatchFile, ListSources, etc.
+    /// Stop the stream
+    async fn stop(&self) -> Result<()>;
 
-## Usage Guide
+    /// Pause notifications (source may continue internally)
+    fn pause(&self);
 
-### Setting Up Data Sources for an Agent
+    /// Resume notifications
+    fn resume(&self);
 
-```rust
-use pattern_core::{
-    agent::DatabaseAgent,
-    data_source::{DataIngestionCoordinator, FileDataSource, FileStorageMode},
-    context::message_router::AgentMessageRouter,
-};
-
-// 1. Create your agent with an embedding provider
-let agent = DatabaseAgent::new(
-    agent_id,
-    user_id,
-    agent_type,
-    name,
-    system_prompt,
-    memory,
-    db.clone(),
-    model_provider,
-    tool_registry,
-    Some(embedding_provider), // Important for indexed sources
-    heartbeat_sender,
-);
-
-// 2. Create the coordinator with the agent's embedding provider
-let message_router = AgentMessageRouter::new(agent_id.clone(), db.clone());
-let coordinator = DataIngestionCoordinator::new(
-    message_router,
-    agent.embedding_provider(), // Reuse agent's provider
-)?;
-
-// 3. Register the DataSourceTool
-pattern_core::tool::builtin::register_data_source_tool(
-    &tool_registry,
-    Arc::new(RwLock::new(coordinator)),
-);
+    /// Current status
+    fn status(&self) -> StreamStatus;
+
+    /// Whether this source supports pull-based access
+    fn supports_pull(&self) -> bool;
+
+    /// Pull items if supported (optional)
+    async fn pull(
+        &self,

+        _cursor: Option<StreamCursor>,
+    ) -> Result<Vec<Notification>> {
+        Ok(vec![])
+    }
+}
 ```
 
-### File Data Source Examples
+#### DataBlock
+
+For document-oriented sources (files, external storage):
 
-#### Simple File Reading
 ```rust
-// Ephemeral mode - no indexing, just read
-let source = FileDataSource::new(
-    "/path/to/file.txt",
-    FileStorageMode::Ephemeral,
-);
-
-// Pull latest content
-let items = source.pull(10, None).await?;
+#[async_trait]

+
+    /// Schema for blocks created by this source
+    fn block_schema(&self) -> BlockSchemaSpec;
+
+    /// Permission rules for block access
+    fn permission_rules(&self) -> Vec<PermissionRule>;
+
+    /// Check if this source handles the given path
+    fn matches(&self, path: &Path) -> bool;
+
+    /// Current status
+    fn status(&self) -> BlockSourceStatus;
+
+    /// Load a document into a memory block
+    async fn load(
+        &self,
+        path: &Path,

+
+    /// Delete a document
+    async fn delete(&self, path: &Path) -> Result<()>;
+
+    /// Reconcile after external changes
+    async fn reconcile(
+        &self,
+        paths: &[PathBuf],
+        ctx: Arc<dyn ToolContext>,
+    ) -> Result<Vec<ReconcileResult>>;
+

+
+    /// Diff between versions
+    async fn diff(
+        &self,

+        from: Option<&str>,
+        to: Option<&str>,
+    ) -> Result<String>;
+}
 ```
 
-#### Indexed File with Semantic Search
+### Supporting Types
+
+#### Notification
+
+Event from a stream source:
+
 ```rust
-// Indexed mode - requires embedding provider
-let source = FileDataSource::new(
-    "/path/to/docs.md",
-    FileStorageMode::Indexed {
-        embedding_provider: agent.embedding_provider().unwrap(),
-        chunk_size: 1000,
-    },
-);
-
-// Content will be chunked and embedded for search
+pub struct Notification {
+    pub id: String,
+    pub batch_id: String,
+    pub source_id: String,
+    pub message: Message,
+    pub block_ids: Vec<String>,
+    pub priority: NotificationPriority,
+    pub created_at: DateTime<Utc>,
+}
 ```
 
-#### Watch File for Changes
-```rust
-let source = FileDataSource::new(path, FileStorageMode::Ephemeral)
-    .with_watch();
+#### BlockRef
 
-// Subscribe to changes
-let stream = source.subscribe(None).await?;
+Reference to a loaded block:
 
-// Process events as they come
-while let Some(event) = stream.next().await {
-    match event {
-        Ok(StreamEvent { item, cursor, timestamp }) => {
-            // Process new file content
-        }
-        Err(e) => {
-            // Handle error
-        }
-    }
+```rust
+pub struct BlockRef {
+    pub block_id: String,
+    pub agent_id: AgentId,
+    pub source_id: String,
+    pub external_path: PathBuf,
+    pub loaded_at: DateTime<Utc>,
+    pub version: Option<String>,
 }
 ```
 
-### Prompt Templates
+#### BlockSchemaSpec
 
-The system uses prompt templates to format data for agents:
+Schema specification for blocks a source creates:
 
 ```rust
-use pattern_core::prompt_template::{PromptTemplate, TemplateRegistry};
-
-// Create a custom template
-let template = PromptTemplate::new(
-    "github_issue",
-    "New issue #{{ number }} by @{{ author }}: {{ title }}\n{{ body }}",
-)?;
-
-// Register it
-let mut registry = TemplateRegistry::new();
-registry.register(template);
-
-// Use it when adding a source
-coordinator.add_source(
-    github_source,
-    buffer_config,
-    "github_issue".to_string(), // Template name
-).await?;
+pub struct BlockSchemaSpec {
+    pub label_template: String,  // e.g., "bluesky_user_{handle}"
+    pub schema: BlockSchema,
+    pub description: String,
+    pub ephemeral: bool,         // Working block vs Core block
+}
 ```
 
-### Default Templates
+## Source Manager
 
-The system includes default templates:
-- `file_changed` - File modification notifications
-- `stream_item` - Generic stream items
-- `bluesky_post` - Bluesky social posts
-- `scheduled_task` - Scheduled task triggers
-- `data_ingestion` - Generic data ingestion
+The `SourceManager` trait (implemented by `RuntimeContext`) coordinates source operations:
 
-### Agent Tool Operations
+```rust
+#[async_trait]
+pub trait SourceManager: Send + Sync + std::fmt::Debug {
+    // Stream operations
+    fn list_streams(&self) -> Vec<String>;
+    fn get_stream_info(&self, source_id: &str) -> Option<StreamSourceInfo>;
+    async fn pause_stream(&self, source_id: &str) -> Result<()>;

+    async fn subscribe_to_stream(
+        &self,
+        agent_id: &AgentId,
+        source_id: &str,
+        ctx: Arc<dyn ToolContext>,
+    ) -> Result<broadcast::Receiver<Notification>>;
+    async fn pull_from_stream(
+        &self,
+        source_id: &str,
+        limit: usize,
+        cursor: Option<StreamCursor>,
+    ) -> Result<Vec<Notification>>;
+
+    // Block operations
+    fn list_block_sources(&self) -> Vec<String>;
+    fn get_block_source_info(&self, source_id: &str) -> Option<BlockSourceInfo>;
+    async fn load_block(&self, source_id: &str, path: &Path, owner: AgentId) -> Result<BlockRef>;
+    async fn create_block(
+        &self,
+        source_id: &str,
+        path: &Path,
+        content: Option<&str>,
+        owner: AgentId,
+    ) -> Result<BlockRef>;
+    async fn save_block(&self, source_id: &str, block_ref: &BlockRef) -> Result<()>;
+    async fn delete_block(&self, source_id: &str, path: &Path) -> Result<()>;
+    fn find_block_source_for_path(&self, path: &Path) -> Option<Arc<dyn DataBlock>>;
+
+    // Edit routing
+    async fn handle_block_edit(&self, edit: &BlockEdit) -> Result<EditFeedback>;
+}
+```

-### Bluesky Firehose Implementation
+### FileSource
 
-The Bluesky firehose data source is fully implemented and uses the rocketman crate for Jetstream consumption:
+Manages file-backed memory blocks:
 
 ```rust
-use rocketman::{
-    connection::JetstreamConnection,
-    handler,
-    ingestion::LexiconIngestor,
-    options::JetstreamOptions,
-    types::event::{Commit, Event, Operation},
-};
-
-pub struct BlueskyFirehoseSource {
-    source_id: String,
-    endpoint: String,
-    filter: BlueskyFilter,
-    current_cursor: Option<BlueskyFirehoseCursor>,
-    stats: SourceStats,
-    buffer: Option<Arc<parking_lot::Mutex<StreamBuffer<BlueskyPost, BlueskyFirehoseCursor>>>>,
-}
+let source = FileSource::from_config(path, &config);
 
-// Rich post structure with facets for mentions/links
-#[derive(Debug, Clone, Serialize, Deserialize)]
-pub struct BlueskyPost {
-    pub uri: String,
-    pub did: String,
-    pub handle: String,
-    pub text: String,
-    pub created_at: DateTime<Utc>,
-    pub reply_to: Option<String>,
-    pub embed: Option<serde_json::Value>,
-    pub langs: Vec<String>,
-    pub labels: Vec<String>,
-    pub facets: Vec<Facet>, // Rich text annotations
-}
+// Load file into block
+let block_ref = source.load(&file_path, owner, ctx.clone()).await?;
 
-// Custom ingestor implementing rocketman's LexiconIngestor trait
-struct PostIngestor {
-    tx: tokio::sync::mpsc::UnboundedSender<Result<StreamEvent<BlueskyPost, BlueskyFirehoseCursor>>>,
-    filter: BlueskyFilter,
-    buffer: Option<Arc<parking_lot::Mutex<StreamBuffer<BlueskyPost, BlueskyFirehoseCursor>>>>,
-}
+// Access via memory
+let doc = memory.get_block(&owner.0, &block_ref.block_id).await?;
+let content = doc.render();
 
-#[async_trait]
-impl LexiconIngestor for PostIngestor {
-    async fn ingest(&self, event: Event<serde_json::Value>) -> anyhow::Result<()> {
-        // Process commit events for posts
-        if let Some(ref commit) = event.commit {
-            if commit.collection == "app.bsky.feed.post" 
-                && matches!(commit.operation, Operation::Create) {
-                // Parse and filter post
-                // Send to channel and buffer
-            }
-        }
-        Ok(())
-    }
-}
+// Modify and save
+doc.set_text("new content", true)?;
+source.save(&block_ref, ctx.clone()).await?;
+```
+
+Features:
+- Path-based matching with globs
+- Permission rules per pattern
+- Reconciliation after external changes
+- Version history via Loro CRDT
+- Diff between versions
+
+## Configuration
+
+### Via TOML
+
+```toml
+[agent.data_sources.bluesky]
+type = "bluesky"
+name = "bluesky"
+target = "Main Support"
+jetstream_endpoint = "wss://jetstream1.us-east.fire.hose.cam/subscribe"
+friends = ["did:plc:friend1"]
+keywords = ["adhd"]
+require_agent_participation = true
+
+[agent.data_sources.notes]
+type = "file"
+name = "notes"
+paths = ["./notes"]
+recursive = true
+include_patterns = ["*.md"]
+
+[[agent.data_sources.notes.permission_rules]]
+pattern = "*.md"
+permission = "read_write"
+```
+
+### Programmatic
+
+```rust
+use pattern_core::config::DataSourceConfig;
 
-// Usage with rocketman's handle_message
-let msg_rx = connection.get_msg_rx();
-let reconnect_tx = connection.get_reconnect_tx();
-let mut ingestors: HashMap<String, Box<dyn LexiconIngestor + Send + Sync>> = HashMap::new();
-ingestors.insert("app.bsky.feed.post".to_string(), Box::new(post_ingestor));
+// Create from config
+let blocks = config.create_blocks(dbs.clone()).await?;
+let streams = config.create_streams(dbs.clone(), tool_context.clone()).await?;
 
-while let Ok(message) = msg_rx.recv_async().await {
-    handler::handle_message(message, &ingestors, reconnect_tx.clone(), cursor_arc.clone()).await?;
+// Register with runtime
+for block in blocks {
+    runtime.register_block_source(block);
+}
+for stream in streams {
+    runtime.register_stream_source(stream);
 }
 ```
 
-## Type Erasure Pattern
+## Notification Routing
 
-The coordinator uses a type erasure pattern to handle concrete data sources generically:
+Streams route notifications to agents or groups:
 
 ```rust
-// Your source has concrete types
-let file_source: FileDataSource; // Item=FileItem, Cursor=FileCursor
-
-// Coordinator wraps it in TypeErasedSource
-coordinator.add_source(file_source, config, template).await?;
-
-// Internally converts to Item=Value, Cursor=Value
-// This allows the coordinator to handle any data source type
+// BlueskyStream starts routing task when target is configured
+let target = config.target.clone();
+let routing_rx = tx.subscribe();
+
+tokio::spawn(async move {
+    route_notifications(routing_rx, target, source_id, ctx).await;
+});
+
+// route_notifications tries agent first, then group
+async fn route_notifications(...) {
+    match router.route_message_to_agent(&target, message.clone(), origin).await {
+        Ok(Some(_)) => { /* routed to agent */ }
+        Ok(None) => {
+            // Agent not found, try as group
+            router.route_message_to_group(&target, message, origin).await?;
+        }
+        Err(e) => { /* handle error */ }
+    }
+}
 ```
 
-## Cursor Management
+## Edit Feedback
 
-Cursors enable resumption after interruption:
+Block sources can provide feedback on edits:
 
-- **Time-based**: For sources ordered by time (e.g., ModTime for files)
-- **Sequence-based**: For sources with sequence numbers (e.g., Bluesky firehose)
-- **Position-based**: For sources with byte/line positions (e.g., log files)
+```rust
+pub enum EditFeedback {
+    Applied { message: Option<String> },
+    Pending { message: Option<String> },
+    Rejected { reason: String },
+}
+```
 
-The system automatically serializes/deserializes cursors for persistence.
+This enables:
+- Validation before writing
+- Async save operations
+- Rejection with explanation
 
 ## Best Practices
 
-1. **Use the agent's embedding provider** - Don't create duplicate providers
-2. **Choose appropriate storage mode** - Indexed only when semantic search is needed
-3. **Set reasonable buffer limits** - Balance between memory usage and data availability
-4. **Use descriptive source IDs** - Makes debugging and monitoring easier
-5. **Handle errors gracefully** - Streams can fail, have retry logic
-6. **Update cursors atomically** - Ensure exactly-once processing
-
-## Future Extensions
-
-The data source abstraction is designed to support:
-- Database change streams
-- Message queue consumers (Kafka, RabbitMQ)
-- WebSocket streams
-- RSS/Atom feeds
-- Email monitoring
-- Calendar event streams
-- IoT sensor data
-
-Each just needs to implement the `DataSource` trait with appropriate Item, Filter, and Cursor types.
\ No newline at end of file
+1. **Use appropriate source type**: DataStream for events, DataBlock for documents
+2. **Configure targets carefully**: Route to groups for coordination, agents for direct processing
+3. **Set permission rules**: Control agent access to external data
+4. **Handle reconciliation**: External changes should trigger reconcile
+5. **Use batching**: BlueskyStream batches posts to reduce notification frequency

-# Database Migration Guide
-
-## Overview
-
-Pattern uses SurrealDB for data persistence, supporting both embedded (local file) and remote (server) configurations. This guide covers migrating from embedded to external SurrealDB instances.
-
-## Database Configuration Types
-
-### Embedded Database (Default)
-```toml
-[database]
-type = "embedded"
-path = "./pattern.db"  # Local file storage
-strict_mode = false
-```
-
-### Remote Database
-```toml
-[database]
-type = "remote"
-url = "ws://localhost:8000"  # or "wss://" for TLS
-username = "root"
-password = "root"
-namespace = "pattern"
-database = "pattern"
-```
-
-## Migration Process: Embedded to External
-
-### Prerequisites
-- SurrealDB CLI installed (`curl -sSf https://install.surrealdb.com | sh`)
-- Access to both source and target databases
-- Sufficient disk space for export file
-
-### Step 1: Export from Embedded Database
-
-Export the entire embedded database to a SurrealQL script:
-
-```bash
-surreal export \
-  --endpoint surrealkv://pattern.db \
-  --namespace pattern \
-  --database pattern \
-  pattern_export.sql
-```
-
-For selective export, use the `--only` flag with specific resources:
-```bash
-surreal export \
-  --endpoint surrealkv://pattern.db \
-  --namespace pattern \
-  --database pattern \
-  --only \
-  --tables agent,message,mem \
-  --records true \
-  pattern_export.sql
-```
-
-### Step 2: Start External SurrealDB Server
-
-Start a SurrealDB server instance:
-
-```bash
-# Development server (in-memory)
-surreal start --log debug --user root --pass root memory
-
-# Production server (with persistent storage)
-surreal start \
-  --log info \
-  --user root \
-  --pass <secure-password> \
-  file://./surrealdb-data
-```
-
-For production deployments, consider using Docker:
-```bash
-docker run --rm -p 8000:8000 \
-  -v $(pwd)/surrealdb-data:/data \
-  surrealdb/surrealdb:latest \
-  start --user root --pass root file://data
-```
-
-### Step 3: Import to External Server
-
-Import the exported data into the external server:
-
-```bash
-surreal import \
-  --endpoint http://localhost:8000 \
-  --username root \
-  --password root \
-  --namespace pattern \
-  --database pattern \
-  pattern_export.sql
-```
-
-### Step 4: Update Pattern Configuration
-
-Modify your `pattern.toml` or `config.toml`:
-
-```toml
-[database]
-type = "remote"
-url = "ws://localhost:8000"  # Use wss:// for TLS connections
-username = "root"
-password = "root"  # Use environment variable in production
-namespace = "pattern"
-database = "pattern"
-```
-
-For production, use environment variables:
-```toml
-[database]
-type = "remote"
-url = "${SURREALDB_URL}"
-username = "${SURREALDB_USER}"
-password = "${SURREALDB_PASS}"
-namespace = "pattern"
-database = "pattern"
-```
-
-### Step 5: Verify Migration
-
-Test the connection and verify data integrity:
-
-```bash
-# Test with Pattern CLI
-pattern-cli agent list
-
-# Or query directly
-echo "SELECT * FROM agent;" | surreal sql \
-  --endpoint http://localhost:8000 \
-  --username root \
-  --password root \
-  --namespace pattern \
-  --database pattern
-```
-
-## Multi-Tenant Setup
-
-For hosting multiple Pattern instances on one SurrealDB server:
-
-### Option 1: Namespace Isolation
-Each tenant gets their own namespace:
-```toml
-# Tenant A
-[database]
-namespace = "tenant_a"
-database = "pattern"
-
-# Tenant B  
-[database]
-namespace = "tenant_b"
-database = "pattern"
-```
-
-### Option 2: Database Isolation
-Each tenant gets their own database within a shared namespace:
-```toml
-# Tenant A
-[database]
-namespace = "pattern"
-database = "tenant_a"
-
-# Tenant B
-[database]
-namespace = "pattern"  
-database = "tenant_b"
-```
-
-## Backup Strategies
-
-### Automated Backups
-Create a backup script (`backup-pattern.sh`):
-```bash
-#!/bin/bash
-TIMESTAMP=$(date +%Y%m%d_%H%M%S)
-BACKUP_FILE="pattern_backup_${TIMESTAMP}.sql"
-
-surreal export \
-  --endpoint ${SURREALDB_URL} \
-  --username ${SURREALDB_USER} \
-  --password ${SURREALDB_PASS} \
-  --namespace pattern \
-  --database pattern \
-  "${BACKUP_FILE}"
-
-# Compress the backup
-gzip "${BACKUP_FILE}"
-
-# Optional: Upload to S3/GCS/Azure
-# aws s3 cp "${BACKUP_FILE}.gz" s3://my-backups/pattern/
-```
-
-Schedule with cron:
-```bash
-# Daily backup at 2 AM
-0 2 * * * /path/to/backup-pattern.sh
-```
-
-### Point-in-Time Recovery
-For production environments, consider SurrealDB's upcoming features:
-- Change Data Capture (CDC)
-- Transaction logs
-- Continuous replication
-
-## Performance Considerations
-
-### Connection Pooling
-Pattern automatically handles connection pooling, but for high-load scenarios:
-- Use WebSocket (`ws://` or `wss://`) instead of HTTP
-- Deploy SurrealDB behind a load balancer for horizontal scaling
-- Consider SurrealDB cluster mode (when available)
-
-### Network Latency
-When migrating from embedded to remote:
-- Expect ~1-5ms latency for local network
-- Expect ~10-50ms latency for cross-region
-- Use connection keep-alive for long-running agents
-- Consider read replicas for geographically distributed deployments
-
-## Troubleshooting
-
-### Common Issues
-
-1. **Connection Refused**
-   - Verify SurrealDB server is running
-   - Check firewall rules
-   - Ensure correct endpoint URL
-
-2. **Authentication Failed**
-   - Verify username/password
-   - Check auth-level (root vs namespace vs database)
-   - Ensure user has correct permissions
-
-3. **Namespace/Database Not Found**
-   - SurrealDB requires explicit namespace/database creation
-   - Run migrations after import: `pattern-cli db migrate`
-
-4. **Schema Mismatch**
-   - Pattern includes automatic migrations
-   - Force schema update: `pattern-cli db migrate --force`
-
-### Debug Commands
-
-```bash
-# Test connection
-surreal isready --endpoint http://localhost:8000
-
-# View server info
-surreal info --endpoint http://localhost:8000 \
-  --username root --password root
-
-# Check database structure
-echo "INFO FOR DB;" | surreal sql \
-  --endpoint http://localhost:8000 \
-  --username root --password root \
-  --namespace pattern --database pattern
-```
-
-## Security Best Practices
-
-1. **Authentication**
-   - Never use default credentials in production
-   - Use strong, unique passwords
-   - Consider JWT tokens for service accounts
-
-2. **Network Security**
-   - Always use TLS (`wss://`) for remote connections
-   - Restrict database access to specific IPs
-   - Use VPN or private networks when possible
-
-3. **Access Control**
-   - Create specific users for Pattern (not root)
-   - Use SurrealDB's RBAC for fine-grained permissions
-   - Audit database access logs regularly
-
-4. **Data Encryption**
-   - Enable encryption at rest for SurrealDB storage
-   - Use encrypted connections (TLS/SSL)
-   - Consider field-level encryption for sensitive data

-# Using External SurrealDB
-
-Pattern supports connecting to an external SurrealDB instance instead of the embedded database. This is useful for production deployments or when you need to share data across multiple Pattern instances.
-
-## Configuration
-
-### 1. Enable the Feature
-
-When building pattern-cli, enable the `surreal-remote` feature:
-
-```bash
-cargo build --release --bin pattern-cli --features surreal-remote
-```
-
-### 2. Configure the Connection
-
-In your `pattern.toml` configuration file, replace the embedded database config with a remote configuration:
-
-```toml
-[database]
-# Instead of:
-# path = "./pattern.db"
-
-# Use:
-url = "ws://localhost:8000"  # or "wss://..." for secure connections
-namespace = "pattern"
-database = "pattern"
-# Optional: specify credentials directly in config
-# username = "root"
-# password = "root"
-```
-
-### 3. Environment Variables
-
-For security, you can provide database credentials through environment variables instead of hardcoding them in the config file:
-
-```bash
-export SURREAL_USER="root"
-export SURREAL_PASS="your-secure-password"
-```
-
-These environment variables will be used if `username` and `password` are not specified in the configuration file.
-
-## Running SurrealDB
-
-To start a SurrealDB server for development:
-
-```bash
-# Install SurrealDB
-curl -sSf https://install.surrealdb.com | sh
-
-# Start with authentication
-surreal start --user root --pass root --bind 0.0.0.0:8000 file://./data.db
-
-# Or start in memory mode for testing
-surreal start --user root --pass root --bind 0.0.0.0:8000 memory
-```
-
-## Migration from Embedded
-
-When migrating from an embedded database to an external one:
-
-1. Export your data using the CAR export feature (format v2):
-   ```bash
-   pattern-cli export constellation -o backup.car
-   ```
-   Notes:
-   - Export format version is 2 (slim agent metadata + chunked blocks, 1MB cap)
-   - Older CARs from pre-v2 builds may not be compatible with all IPLD tools
-
-2. Update your configuration to use the external database
-
-3. Import your data:
-   ```bash
-   pattern-cli import backup.car
-   ```
-
-## Security Considerations
-
-- Never commit credentials to version control
-- Use environment variables for production deployments
-- Consider using TLS (wss://) for production connections
-- Restrict database access to trusted networks only

 # Pattern Group Coordination
 
-Pattern's group coordination system allows multiple agents to work together, routing messages through various coordination patterns. This enables complex multi-agent behaviors like round-robin discussions, dynamic expertise selection, and pipeline processing.
+Pattern's group coordination system enables multiple agents to work together through various patterns. This guide covers how to create, configure, and use agent groups.
 
-## Core Components
+## Core Concepts
 
-### 1. Agent Groups
+### Agent Groups
+
+A group is a collection of agents that coordinate using a specific pattern:
 
 ```rust
 pub struct AgentGroup {
@@ -13,120 +15,150 @@ pub struct AgentGroup {
     pub description: String,
     pub coordination_pattern: CoordinationPattern,
     pub state: GroupState,
-    pub members: Vec<GroupMember>,
-    // ...
+    pub members: Vec<(AgentModel, GroupMembership)>,
 }
 ```
 
-Groups are collections of agents that work together using a specific coordination pattern.
+### Coordination Patterns
 
-### 2. Coordination Patterns
+Six patterns are available:
 
 ```rust
-#[derive(Debug, Clone, Serialize, Deserialize)]
 pub enum CoordinationPattern {
-    RoundRobin { current_index: usize, skip_unavailable: bool },
-    Dynamic { selector: String, config: HashMap<String, String> },
-    Pipeline { stages: Vec<PipelineStage> },
-    Supervisor { supervisor_agent_id: AgentId },
-    Voting { min_votes: usize, require_majority: bool },
-    Sleeptime { check_interval_ms: u64, intervention_threshold: f32 },
+    Supervisor { leader_id, delegation_rules },
+    RoundRobin { current_index, skip_unavailable },
+    Voting { quorum, voting_rules },
+    Pipeline { stages, parallel_stages },
+    Dynamic { selector_name, selector_config },
+    Sleeptime { check_interval, triggers, intervention_agent_id },
 }
 ```
 
-Each pattern implements a different strategy for routing messages between agents.
-
-### 3. Group Managers
+### Member Roles
 
 ```rust
-#[async_trait]
-pub trait GroupManager: Send + Sync {
-    async fn route_message(
-        &self,
-        group: &AgentGroup,
-        agents: &[AgentWithMembership<Arc<dyn Agent>>],
-        message: Message,
-    ) -> Result<GroupResponse>;
+pub enum GroupMemberRole {
+    Regular,                    // Standard member
+    Supervisor,                 // Group leader
+    Observer,                   // Receives messages but doesn't respond
+    Specialist { domain: String }, // Expert in a domain
 }
 ```
 
-Managers implement the logic for each coordination pattern.
-
 ## Coordination Patterns Explained
 
-### Round Robin
-Cycles through agents in order, optionally skipping inactive ones.
+### Supervisor
+
+One agent leads, delegating tasks to others:
 
 ```mermaid
-graph LR
-    M[Message] --> A1[Agent 1]
-    A1 --> A2[Agent 2]
-    A2 --> A3[Agent 3]
-    A3 --> A1
-    style M fill:#4299e1,stroke:#2b6cb0,color:#fff
+graph TB
+    M[Message] --> L[Leader Agent]
+    L -->|Delegate| W1[Worker 1]
+    L -->|Delegate| W2[Worker 2]
+    L --> R[Synthesized Response]
+```
+
+```toml
+[groups.pattern]
+type = "supervisor"
+leader = "Pattern"
+
+[groups.pattern.delegation_rules]
+max_delegations_per_agent = 3
+delegation_strategy = "capability"  # round_robin, least_busy, random
+fallback_behavior = "handle_self"   # queue, fail
 ```
 
 **Use Cases:**
-- Fair distribution of work
-- Team discussions where everyone gets a turn
-- Load balancing simple tasks
+- Task delegation with oversight
+- Quality control
+- Hierarchical coordination
+
+### Round Robin
 
-### Dynamic Selection
-Uses selectors to choose agents based on various criteria.
+Agents take turns in order:
 
 ```mermaid
-graph TB
-    M[Message] --> S{Selector}
-    S -->|Capability Match| A1[Expert Agent]
-    S -->|Random| A2[Any Agent]
-    S -->|Load Balance| A3[Least Busy]
-    style M fill:#4299e1,stroke:#2b6cb0,color:#fff
-    style S fill:#ed8936,stroke:#c05621,color:#fff
+graph LR
+    M[Message] --> A1[Agent 1]
+    A1 -.next.-> A2[Agent 2]
+    A2 -.next.-> A3[Agent 3]
+    A3 -.next.-> A1
 ```
 
-**Available Selectors:**
-- **Capability**: Matches agent capabilities to message needs
-- **Random**: Random selection for variety
-- **LoadBalancing**: Chooses least recently used agent
+```toml
+[groups.pattern]
+type = "round_robin"
+skip_unavailable = true  # Skip inactive agents
+```
+
+**Use Cases:**
+- Fair distribution of work
+- Load balancing
+- Team discussions
 
 ### Pipeline
-Processes messages through a sequence of stages.
+
+Sequential processing through stages:
 
 ```mermaid
 graph LR
-    M[Message] --> S1[Analyzer Agent]
-    S1 --> S2[Planner Agent]
-    S2 --> S3[Executor Agent]
-    S3 --> R[Combined Result]
-    style M fill:#4299e1,stroke:#2b6cb0,color:#fff
-    style R fill:#48bb78,stroke:#2f855a,color:#fff
+    M[Message] --> S1[Analysis Stage]
+    S1 --> S2[Planning Stage]
+    S2 --> S3[Execution Stage]
+    S3 --> R[Result]
+```
+
+```toml
+[groups.pattern]
+type = "pipeline"
+stages = ["Analyzer", "Planner", "Executor"]
+parallel_stages = false
+
+# Stage failure handling (in code)
+# on_failure = "skip" | "retry" | "abort" | "fallback"
 ```
 
 **Use Cases:**
-- Multi-step analysis (understand → plan → execute)
-- Document processing pipelines
-- Complex workflows with dependencies
+- Multi-step workflows
+- Analysis pipelines
+- Document processing
 
-### Supervisor
-One agent reviews and can modify other agents' responses.
+### Dynamic
+
+Context-based agent selection:
 
 ```mermaid
 graph TB
-    M[Message] --> W[Worker Agent]
-    W --> S{Supervisor}
-    S -->|Approved| R1[Final Response]
-    S -->|Modified| R2[Edited Response]
-    style M fill:#4299e1,stroke:#2b6cb0,color:#fff
-    style S fill:#ed8936,stroke:#c05621,color:#fff
+    M[Message] --> S{Selector}
+    S -->|Capability Match| A1[Expert Agent]
+    S -->|Load Balance| A2[Least Busy]
+    S -->|Random| A3[Any Agent]
 ```
 
-**Use Cases:**
-- Quality control
-- Safety filtering
-- Response refinement
+```toml
+[groups.pattern]
+type = "dynamic"
+selector = "capability"  # random, load_balancing, supervisor
+
+[groups.pattern.selector_config]
+preferred_domain = "task_management"
+```
+
+**Available Selectors:**
+- `random`: Random selection
+- `capability`: Match message content to agent capabilities
+- `load_balancing`: Select least recently used agent
+- `supervisor`: LLM-based selection by supervisor agent
+
+**Special Addressing:**
+- `@all`: Broadcast to all active agents
+- `@agentname` or `agentname:`: Route directly to named agent
 
 ### Voting
-Multiple agents vote on responses or decisions.

-## Creating and Using Groups
-
-### Step 1: Create a Group via CLI
-
-```bash
-# Create a group with round-robin pattern
-pattern-cli group create TaskForce \
-  --description "Multi-agent task force" \
-  --pattern round-robin
-
-# Create with dynamic selection
-pattern-cli group create Experts \
-  --description "Expert selection group" \
-  --pattern dynamic \
-  --selector capability
+    A --> I[Proactive Message]
 ```
 
-### Step 2: Add Agents to the Group
-
-```bash
-# Add agents with specific roles
-pattern-cli group add-member TaskForce analyzer \
-  --role "Analysis Expert"
-
-pattern-cli group add-member TaskForce planner \
-  --role "Strategic Planner"
-
-pattern-cli group add-member TaskForce executor \
-  --role "Task Executor"

+priority = "medium"
+[groups.pattern.triggers.condition]
+type = "constellation_activity"
+message_threshold = 20
+time_threshold = 3600
 ```
 
-### Step 3: Chat with the Group
+**Trigger Conditions:**
+- `time_elapsed`: Duration since last activity
+- `pattern_detected`: Named pattern recognition
+- `threshold_exceeded`: Metric over threshold
+- `constellation_activity`: Message count or time thresholds
+- `custom`: Custom evaluator
 
-```bash
-# Start group chat
-pattern-cli chat --group TaskForce
+**Use Cases:**
+- ADHD hyperfocus monitoring
+- Periodic check-ins
+- Background task management
 
-# The coordination pattern will route your messages
-# according to the group's configuration

-    user.id.clone(),
-    "BrainTrust",
-    "Executive function support",

-    G --> P[Pattern Manager]
-    P --> S[Select Agents]

+# Create group from TOML template
+pattern group create --from crisis.toml
+
+# Add member
+pattern group add member "Crisis Response" Pattern --role regular
+
+# View status
+pattern group status "Crisis Response"
 
-### Detailed Flow:
+# Edit group (interactive TUI builder)
+pattern group edit "Crisis Response"
 
-1. **Message Received**: User sends message to group
-2. **Pattern Routing**: GroupCoordinator identifies the pattern
-3. **Manager Selection**: Appropriate GroupManager is instantiated
-4. **Agent Selection**: Manager determines which agents to invoke
-5. **Execution**: Agents process message (parallel or sequential)
-6. **Response Collection**: All agent responses are gathered
-7. **State Update**: Group state is updated if needed
-8. **Combined Response**: Formatted response returned to user
+# Export configuration
+pattern group export "Crisis Response" -o crisis.toml
+```
 
-## Advanced Features
+## Response Streaming
 
-### Dynamic Selector Configuration
+Groups emit events during message processing:
 
 ```rust
-// Capability-based selection with tag matching
-let mut config = HashMap::new();
-config.insert("match_mode".to_string(), "any".to_string()); // or "all"
-config.insert("min_score".to_string(), "0.7".to_string());
-
-// Load balancing with time windows
-config.insert("window_minutes".to_string(), "30".to_string());
-config.insert("count".to_string(), "2".to_string()); // Select top 2
+pub enum GroupResponseEvent {
+    Started { group_id, pattern, agent_count },
+    AgentStarted { agent_id, agent_name, role },
+    TextChunk { agent_id, text, is_final },
+    ReasoningChunk { agent_id, text, is_final },
+    ToolCallStarted { agent_id, call_id, fn_name, args },
+    ToolCallCompleted { agent_id, call_id, result },
+    AgentCompleted { agent_id, agent_name, message_id },
+    Complete { group_id, pattern, execution_time, agent_responses, state_changes },
+    Error { agent_id, message, recoverable },
+}
 ```
 
-### Pipeline Stage Configuration
+### Usage Example
 
 ```rust
-PipelineStage {
-    name: "analysis".to_string(),
-    agent_selector: AgentSelector::ByCapability {
-        required: vec!["analysis".to_string()],
-        preferred: vec!["deep_analysis".to_string()],
-    },
-    timeout_ms: Some(30000),
-    optional: false,
+use pattern_core::coordination::{DynamicManager, DefaultSelectorRegistry};
+
+let registry = Arc::new(DefaultSelectorRegistry::new());
+let manager = DynamicManager::new(registry);
+
+let mut stream = manager.route_message(&group, &agents, message).await?;
+
+use tokio_stream::StreamExt;
+while let Some(event) = stream.next().await {
+    match event {
+        GroupResponseEvent::TextChunk { agent_id, text, .. } => {
+            println!("[{}]: {}", agent_id, text);
+        }
+        GroupResponseEvent::Complete { execution_time, .. } => {
+            println!("Completed in {:?}", execution_time);
+        }
+        _ => {}
+    }
 }
 ```
 
-### Group State Management
+## Group State
 
-Groups maintain state between interactions:
+Each pattern maintains its own state:
 
 ```rust
 pub enum GroupState {
-    RoundRobin { current_index: usize, last_rotation: DateTime<Utc> },
-    Pipeline { completed_stages: Vec<String>, stage_results: Map<String, Value> },
-    Voting { current_votes: Map<AgentId, Vote>, voting_deadline: DateTime<Utc> },
-    // ...
+    Supervisor { current_delegations: HashMap<AgentId, usize> },
+    RoundRobin { current_index, last_rotation },
+    Voting { active_session: Option<VotingSession> },
+    Pipeline { active_executions: Vec<PipelineExecution> },
+    Dynamic { recent_selections: Vec<(DateTime<Utc>, AgentId)> },
+    Sleeptime { last_check, trigger_history, current_index },
 }
 ```
 
-## Troubleshooting
+State is automatically updated after each message and persisted to the database.
 
-### Common Issues
+## Memory Sharing
 
-1. **"No agents available"**
-   - Check agents are active: `pattern-cli group status <name>`
-   - Verify membership: Agents must be added to group
-   - For capability selector: Ensure agents have required capabilities
+Agents in a group can share memory blocks:
 
-2. **Round-robin skipping agents**
-   - Check `skip_unavailable` setting
-   - Verify agent state is not `Inactive`
-   - Look for filtered agents in logs
+```rust
+// Share a block with another agent
+db.share_block(owner_id, block_id, recipient_id, MemoryPermission::ReadOnly).await?;
 
-3. **Pipeline stage failures**
-   - Check timeout settings
-   - Verify all stages have available agents
-   - Review stage dependencies
+// Access shared content
+let doc = memory.get_shared_block(recipient_id, owner_id, "shared_notes").await?;

 ## Best Practices
 
-### 1. Choose the Right Pattern
+### Pattern Selection
+
+| Pattern | Best For |
+|---------|----------|
+| Supervisor | Delegation, quality control |
+| RoundRobin | Fair distribution, load balancing |
+| Pipeline | Sequential workflows |
+| Dynamic | Expertise matching |
+| Voting | Critical decisions |
+| Sleeptime | Background monitoring |
 
-- **Round-Robin**: Equal participation, fairness
-- **Dynamic**: Expertise matching, load distribution
-- **Pipeline**: Sequential processing, workflows
-- **Supervisor**: Quality control, safety
-- **Voting**: Critical decisions, consensus
-- **Sleeptime**: Background monitoring, alerts
+### Agent Capabilities
 
-### 2. Agent Capabilities
+Define specific, actionable capabilities:
 
-Define clear, specific capabilities:
 ```toml
-# Good
-capabilities = ["python_code_review", "security_analysis", "test_generation"]
+# Good - specific and matchable
+capabilities = ["task_breakdown", "time_estimation", "priority_analysis"]
 
-# Too vague
-capabilities = ["coding", "analysis"]
+# Too vague - hard to match
+capabilities = ["help", "support"]
 ```
 
-### 3. Group Composition
+### Group Composition
 
-- Keep groups focused on specific purposes
+- Keep groups focused (3-7 members typically optimal)
 - Mix complementary capabilities
-- Consider group size (3-7 agents typically optimal)
-- Use roles to clarify each agent's purpose
+- Assign clear roles
+- Consider overlapping group memberships for different contexts
 
-### 4. State Management
+### Overlapping Groups
 
-- Groups persist state between conversations
-- Reset state if behavior becomes unexpected
-- Monitor state in long-running groups
+The same agent can belong to multiple groups:
 
-## Integration with Memory System
+```
+Pattern Agent
+├── Main Support (Dynamic)
+├── Crisis Response (RoundRobin)
+├── Planning (Supervisor - as member)
+└── Sleeptime (Sleeptime - as intervener)
+```
 
-Groups can share memory between agents:
+## Troubleshooting
 
-```rust
-// Agents in a group can share memory blocks
-agent1.share_memory_with(
-    "project_context",
-    agent2.id(),
-    MemoryPermission::Read,
-).await?;
-```
+### "No agents available"
+
+1. Check agent states: `pattern agent list`
+2. Verify group membership: `pattern group status <name>`
+3. For capability selector: Ensure agents have matching capabilities
+
+### Round-robin skipping agents
+
+1. Check `skip_unavailable` setting
+2. Verify member `is_active` status
+3. Review agent logs for errors
+
+### Pipeline stage failures
 
-This enables:
-- Shared context across pipeline stages
-- Persistent group knowledge
-- Collaborative memory building
+1. Check timeout settings
+2. Verify stage agents are available
+3. Review `on_failure` action (skip, retry, abort, fallback)
 
-## Future Enhancements
+### Dynamic selection issues
 
-Planned improvements include:
-- Weighted voting based on expertise
-- Dynamic pattern switching based on context
-- Group templates for common ADHD support patterns
-- Inter-group communication protocols
-- Group performance analytics
+1. Enable debug logging: `RUST_LOG=pattern_core::coordination=debug`
+2. Check selector configuration
+3. Verify agent capabilities match message content

+
+## Non-MCP Tool Schema Issues (AiTool/JsonSchema)
+
+For Pattern's internal `AiTool` trait using `schemars::JsonSchema`, there are additional pitfalls:
+
+### Doc Comments on Enum Variants Cause `oneOf`
+
+When you add doc comments to enum variants, `schemars` generates a `oneOf` schema with `const` values. Some LLM APIs (notably Gemini) don't handle `oneOf`/`const` patterns well.
+
+**Problematic:**
+```rust
+#[derive(JsonSchema, Serialize, Deserialize)]
+#[serde(rename_all = "snake_case")]
+pub enum ShellOp {
+    /// Execute a command and wait for completion.
+    Execute,
+    /// Spawn a long-running process.
+    Spawn,
+}
+```
+
+This generates:
+```json
+{
+  "oneOf": [
+    { "const": "execute", "description": "Execute a command..." },
+    { "const": "spawn", "description": "Spawn a long-running..." }
+  ]
+}
+```
+
+**Fixed - no doc comments on variants:**
+```rust
+#[derive(JsonSchema, Serialize, Deserialize)]
+#[serde(rename_all = "snake_case")]
+pub enum ShellOp {
+    Execute,
+    Spawn,
+}
+```
+
+This generates a simpler enum schema that works across all providers:
+```json
+{
+  "type": "string",
+  "enum": ["execute", "spawn"]
+}
+```
+
+**Rule**: If you need multi-provider LLM compatibility, avoid doc comments on enum variants. Put documentation at the enum level or in the containing struct's field description instead.

+# Interactive TUI Builders
+
+Pattern includes interactive terminal UI builders for creating and editing agents and groups. These builders provide a guided experience with live configuration previews, section-based editing, and multiple save options.
+
+## Quick Start
+
+```bash
+# Create a new agent interactively
+pattern agent create
+
+# Edit an existing agent
+pattern agent edit MyAgent
+
+# Create a new group interactively
+pattern group create
+
+# Edit an existing group
+pattern group edit MyGroup
+
+# Load from TOML template
+pattern agent create --from template.toml
+pattern group create --from template.toml
+```
+
+## How Builders Work
+
+Both builders follow the same interaction pattern:
+
+1. **Summary Display**: Shows a formatted overview of the current configuration
+2. **Section Menu**: Choose which section to edit, or finish/cancel
+3. **Section Editor**: Interactive prompts to modify that section's values
+4. **Repeat**: After each section edit, returns to the summary view
+5. **Save Options**: When done, choose where to save (database, file, both, or preview)
+
+### Navigation
+
+- Use arrow keys or number keys to select menu options
+- Press Enter to confirm selections
+- Type values directly when prompted
+- Use `@filepath` syntax to link to external files (e.g., `@./prompts/system.md`)
+- Empty input typically means "keep current value"
+
+## Agent Builder
+
+### Sections
+
+#### Basic Info
+- **Name**: Agent identifier (required)
+- **System Prompt**: Core instructions, either inline or `@path/to/file.md`
+- **Persona**: Agent personality/character description
+- **Instructions**: Additional operational guidelines
+
+#### Model
+- **Provider**: anthropic, openai, gemini, or ollama
+- **Model Name**: Specific model (e.g., claude-sonnet-4-20250514, gpt-4o)
+- **Temperature**: Response creativity (0.0-1.0)
+
+#### Memory Blocks
+Manage agent's memory:
+- **Add**: Create new memory blocks
+- **Edit**: Modify existing blocks
+- **Remove**: Delete blocks
+- **Edit as TOML**: View TOML representation (preview)
+
+Block properties:
+- **Label**: Identifier for the block (e.g., "human", "persona", "notes")
+- **Content**: Text content or `@path` to file
+- **Permission**: read_only, read_write, append, partner, human, admin
+- **Type**: core (always in context), working (swappable), archival (searchable)
+- **Shared**: Whether other agents can access this block
+
+#### Tools & Rules
+- **Tools**: Multi-select from available tools (block, recall, search, send_message, web, file, calculator, etc.)
+- **Rules**: Add workflow rules for tool execution:
+  - ContinueLoop: Tool continues conversation loop
+  - ExitLoop: Tool ends conversation when called
+  - StartConstraint: Tool must be called first
+  - MaxCalls: Limit how many times tool can be called
+  - Cooldown: Minimum time between calls
+  - RequiresPreceding: Tool requires other tools to be called first
+
+#### Context Options
+- **Max Messages**: Limit messages in context window
+- **Enable Thinking**: Turn on reasoning/thinking mode
+
+#### Data Sources
+Configure event-driven data inputs:
+- **Bluesky**: Jetstream firehose subscriptions
+- **Discord**: Channel monitoring
+- **File**: File system watching
+- **Custom**: Custom source configuration
+
+#### Integrations
+- **Bluesky Handle**: Link agent to a Bluesky identity

+
+## Save Options
+
+When you select "Done - Save", you'll choose where to save:
+
+1. **Save to database**: Writes directly to pattern_db
+2. **Export to file**: Saves as TOML file (prompts for filename)
+3. **Both**: Database and file
+4. **Preview**: Shows TOML representation without saving
+5. **Cancel**: Returns to editing
+
+## Tips
+
+### File References
+Use `@` prefix to link to external files:
+```
+System prompt: @./prompts/assistant.md
+Persona: @./personas/helpful.md
+```
+This keeps large prompts maintainable and version-controlled.
+
+### State Recovery
+Builders auto-save state to `~/.cache/pattern/builder-state.toml` after each section edit. If the builder crashes, the next run can potentially recover.
+
+### TOML Templates
+Create templates by exporting existing configurations:
+```bash
+pattern agent export MyAgent -o template.toml
+# Edit template.toml
+pattern agent create --from template.toml
+```
+
+### Validation
+Builders validate configuration before saving:
+- Agent: Name and model are required
+- Group: Name, description, and valid pattern configuration required
+- Supervisor pattern: Leader must be specified
+- Pipeline pattern: At least one stage required
+
+## TOML Configuration Reference
+
+### Agent TOML Structure
+
+```toml
+name = "MyAgent"
+system_prompt = "You are a helpful assistant."

+# Jacquard Patterns for Pattern
+
+This document captures key patterns and insights for working with [Jacquard](https://tangled.org/nonbinary.computer/jacquard), the zero-copy AT Protocol library.
+
+## Core Principle: Preserve Types, Convert at Boundaries
+
+Jacquard's validated string types (`Did`, `AtUri`, `Handle`, `Nsid`, `Cid`, etc.) are not just type safety - they're often **cheaper than `String`**. Don't convert to String unless you're at an output boundary.
+
+```rust
+// BAD: Loses type info AND allocates
+let did_string = did.to_string();
+map.insert(did_string, value);
+
+// GOOD: Preserves type AND often cheaper
+let did_static = did.clone().into_static();
+map.insert(did_static, value);
+```
+
+## Why Jacquard Types Are Cheap
+
+All jacquard string types wrap `CowStr<'a>`, which is an enum over:
+
+| Variant | When Used | Cost |
+|---------|-----------|------|
+| Borrowed slice | Parsing from buffer | Zero allocation |
+| SmolStr (inlined) | Strings ≤23 bytes | Stack only, no heap |
+| SmolStr (static) | `new_static()` calls | Zero cost, binary reference |
+| SmolStr (Arc) | Larger owned strings | Single allocation, cheap clone |
+
+Most DIDs, handles, and rkeys are small enough to inline. Even when they need Arc, cloning is just an atomic increment - no memcpy.
+
+### Across Await Boundaries
+
+```rust
+// OLD THINKING: "Need String to cross await points"
+let did_string = did.to_string();  // Allocates!
+do_async_thing().await;
+use_did(&did_string);
+
+// CORRECT: Did<'static> is Send + Sync
+let did_static = did.clone().into_static();  // Often just copies inline bytes
+do_async_thing().await;
+use_did(&did_static);  // Still typed, often cheaper
+```
+
+The `'static` lifetime means the data is either:
+- Inlined in the struct (no external references)
+- A static reference to binary data
+- Owned via Arc (reference counted)
+
+All of these are `Send + Sync` and cross await points fine.
+
+## Accessing Untyped Data
+
+`PostView.record` and similar fields are `Data<'a>` (jacquard's replacement for `serde_json::Value`). To access fields:
+
+### Simple Field Access: `get_at_path()`
+
+```rust
+// Get a known field by path
+let text = post_view.record
+    .get_at_path(".text")
+    .and_then(|v| v.as_str())
+    .unwrap_or("");
+
+// Nested paths work too
+let root_uri = post_view.record
+    .get_at_path(".reply.root.uri")
+    .and_then(|v| v.as_str());
+```
+
+### Complex Queries: `query()`
+
+For more complex operations, `Data::query()` provides powerful querying capabilities. See jacquard documentation for full syntax.
+
+### Full Deserialization: `from_data()`
+
+When you need the full typed struct:
+
+```rust
+use jacquard::common::from_data;
+use jacquard::api::app_bsky::feed::post::Post;
+
+let post: Post<'_> = from_data(&post_view.record)?;
+// Now you have full type access
+let text = post.text.as_ref();
+let reply = post.reply.as_ref();
+```
+
+Trade-off: `from_data()` validates the entire structure, `get_at_path()` just navigates to what you need.
+
+## Type Preservation Patterns
+
+### Function Parameters
+
+```rust
+// BAD: Loses type info at call site
+fn process_author(did: &str) { ... }
+
+// GOOD: Preserves type, enables type-safe operations
+fn process_author(did: &Did<'_>) { ... }
+```
+
+### Collection Keys
+
+```rust
+// BAD: String keys lose type info
+let hydrated: DashMap<String, PostView<'static>> = DashMap::new();
+
+// GOOD: Typed keys
+let hydrated: DashMap<AtUri<'static>, PostView<'static>> = DashMap::new();
+```
+
+### Comparisons
+
+```rust
+// BAD: Allocates just to compare
+if did.to_string() == other.to_string() { ... }
+
+// GOOD: Compare underlying strings
+if did.as_str() == other.as_str() { ... }
+```
+
+### Config Structs (The Exception)
+
+Config structs that use `#[derive(Deserialize)]` need `DeserializeOwned`, which requires owned data. Use `String` in configs, then convert at the boundary:
+
+```rust
+#[derive(Deserialize)]
+struct Config {
+    friends: Vec<String>,  // String is fine here
+}
+
+// At runtime, compare with .as_str()
+if config.friends.iter().any(|f| f == did.as_str()) { ... }
+```
+
+## Constructor Patterns
+
+| Method | Allocates? | Use When |
+|--------|-----------|----------|
+| `Did::new(&str)` | No | Parsing from existing buffer |
+| `Did::new_static("...")` | No | Compile-time known strings |
+| `Did::new_owned(String)` | Reuses | You already have a String |
+| `"...".parse::<Did>()` | **Yes** | Avoid - always allocates |
+
+```rust
+// BEST: Zero allocation for known strings
+let nsid = Nsid::new_static("app.bsky.feed.post")?;
+
+// GOOD: Borrows from input
+let did = Did::new(did_str)?;
+
+// AVOID: FromStr always allocates
+let did: Did = did_str.parse()?;
+```
+
+## Response Handling
+
+XRPC responses wrap a `Bytes` buffer:
+
+```rust
+let response = agent.send(request).await?;
+
+// Option 1: Borrow from buffer (zero-copy, must keep response alive)
+let output = response.parse()?;
+process(&output);  // OK
+drop(response);    // Now output is invalid
+
+// Option 2: Convert to owned (allocates, can outlive response)
+let output = response.into_output()?;
+drop(response);    // Fine, output is 'static
+return output;     // Can return from function
+```
+
+## Summary
+
+1. **Preserve jacquard types** through your code - they're optimized for exactly these use cases
+2. **Use `.into_static()` when storing** - it's often just copying inline bytes
+3. **Use `.as_str()` for comparisons** - no allocation needed
+4. **Use `get_at_path()` for simple field access** on `Data<'_>`
+5. **Convert to String only at output boundaries** - notification text, API responses, etc.
+6. **Config structs are the exception** - use String there, compare with `.as_str()`

-# Known API Issues
-
-This document tracks known issues with various model provider APIs and their workarounds.
-
-## Anthropic Claude Issues
-
-### 1. Thinking Mode Message Compression Error
-
-**Error**: 
-```
-Expected `thinking` or `redacted_thinking`, but found `tool_use`. When `thinking` is enabled, a final `assistant` message must start with a thinking block
-```
-
-**Context**: 
-When using Anthropic's thinking mode (enabled by default in Pattern), message compression can create invalid message sequences. If the final assistant message after compression contains tool use blocks, it must start with a thinking block.
-
-**Current Status**: Fix implemented as of 2025-08-04
-
-**Fix Applied**:
-- Modified message truncation strategy in MessageCompressor
-- Assistant messages with thinking blocks are preserved during compression, especially those near the end
-- Instead of modifying messages, the fix attempts to keep important messages intact
-- This preserves the exact thinking content which may be contextually important
-
-**Remaining Work**:
-- Monitor for edge cases where thinking mode messages still cause issues
-- Make thinking mode configurable per agent rather than global
-
-## Gemini API Issues
-
-### 1. Missing Response Path Error
-
-**Error**:
-```
-JsonValueExt(PropertyNotFound("/candidates/0/content/parts"))
-```
-
-**Context**:
-Gemini API response structure may vary, and the genai crate expects a specific path that doesn't always exist. This happens during heartbeat continuations when the response structure differs from expected.
-
-**Current Status**: Active issue as of 2025-08-03 (in genai crate dependency)
-
-**Root Cause**:
-- The error occurs in the genai crate when it tries to extract content from Gemini responses
-- Gemini sometimes returns responses without the expected `/candidates/0/content/parts` structure
-- This is more likely during error conditions or rate limiting
-
-**Workaround**:
-- Retry the request after a short delay
-- Consider switching to a different model temporarily
-- Monitor Gemini API status for service issues
-
-**Fix Plan**:
-- This needs to be fixed in the genai crate itself
-- Could fork genai and add more robust response parsing
-- Alternative: wrap model calls with retry logic that catches this specific error
-
-## General Database Issues
-
-### 1. Transaction Conflicts
-
-**Error**:
-```
-Failed to commit transaction due to a read or write conflict. This transaction can be retried
-```
-
-**Context**:
-SurrealDB transaction conflicts can occur during concurrent message persistence.
-
-**Current Status**: Retry logic implemented but may need tuning
-
-**Workaround**:
-- System already retries with backoff
-- May need to adjust retry parameters

+# Action Items: pattern_core and pattern_cli Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Address critical and high-priority TODOs in pattern_core and pattern_cli from docs/action-items.md
+
+**Architecture:** Fix CRDT memory editing, reimplement CLI commands using pattern_db queries, add missing permission checks and response collection in coordination patterns.
+
+**Tech Stack:** Rust, sqlx, loro, pattern_db FTS5 search, tokio
+
+---
+
+## Task 1: Fix Memory Edit Operation (Critical)
+
+**Files:**
+- Modify: `crates/pattern_core/src/memory/cache.rs:1283-1295`
+- Reference: `crates/pattern_core/src/tool/builtin/block_edit.rs:239-310` (pattern to follow)
+
+**Context:**
+The current `replace_in_block_with_options` does a naive string replace that loses CRDT semantics:
+```rust
+let current = doc.text_content();
+let new_content = current.replacen(old, new, 1);
+doc.set_text(&new_content, true)?;
+```
+
+The block_edit tool shows the correct pattern: use `text.splice()` with proper byte-to-Unicode position conversion.
+
+**Step 1: Write the failing test**
+
+Add to `crates/pattern_core/src/memory/cache.rs` tests:
+
+```rust
+#[tokio::test]
+async fn test_cache_replace_preserves_crdt_operations() {
+    let (_dir, dbs) = test_dbs().await;
+    let cache = MemoryCache::new(dbs.clone());
+
+    // Create test agent
+    let agent = Agent {
+        id: "test-agent".to_string(),
+        name: "Test".to_string(),
+        // ... minimal fields
+    };
+    pattern_db::queries::create_agent(dbs.constellation().pool(), &agent).await.unwrap();
+
+    // Create a text block with initial content
+    cache.create_block(
+        "test-agent",
+        "test_block",
+        "Test block",
+        BlockType::Working,
+        BlockSchema::text(),
+        2000,
+    ).await.unwrap();
+
+    cache.update_block_text("test-agent", "test_block", "Hello world, hello universe").await.unwrap();
+
+    // Get the block and check initial version
+    let doc = cache.get_block("test-agent", "test_block").await.unwrap().unwrap();
+    let initial_version = doc.inner().oplog_vv();
+
+    // Replace first "hello" with "goodbye"
+    let replaced = cache.replace_in_block_with_options(
+        "test-agent",
+        "test_block",
+        "hello",
+        "goodbye",
+        WriteOptions::default(),
+    ).await.unwrap();
+
+    assert!(replaced);
+
+    // Verify content
+    let content = cache.get_rendered_content("test-agent", "test_block").await.unwrap().unwrap();
+    assert_eq!(content, "Hello world, goodbye universe");
+
+    // Verify CRDT version advanced (not reset)
+    let doc = cache.get_block("test-agent", "test_block").await.unwrap().unwrap();
+    let new_version = doc.inner().oplog_vv();
+    assert!(new_version != initial_version, "Version should have advanced via splice, not reset");
+}
+```
+
+**Step 2: Run test to verify it fails**
+
+Run: `cargo nextest run -p pattern-core test_cache_replace_preserves_crdt_operations`
+Expected: The test may pass or fail depending on current behavior, but the key is verifying CRDT semantics are preserved.
+
+**Step 3: Implement proper CRDT replace**
+
+Replace the TODO section in `cache.rs:1283-1295`:
+
+```rust
+// Get current text and replace using CRDT operations
+let text = doc.inner().get_text("content");
+let current = text.to_string();
+
+// Find the position of old text
+let Some(byte_pos) = current.find(old) else {
+    return Ok(false); // Pattern not found
+};
+
+// Convert byte positions to Unicode positions for Loro
+use loro::cursor::PosType;
+let unicode_start = text
+    .convert_pos(byte_pos, PosType::Bytes, PosType::Unicode)
+    .ok_or_else(|| MemoryError::OperationFailed {
+        operation: "replace".to_string(),
+        cause: format!("Invalid byte position: {}", byte_pos),
+    })?;
+let unicode_end = text
+    .convert_pos(byte_pos + old.len(), PosType::Bytes, PosType::Unicode)
+    .ok_or_else(|| MemoryError::OperationFailed {
+        operation: "replace".to_string(),
+        cause: format!("Invalid byte position: {}", byte_pos + old.len()),
+    })?;
+
+// Splice the text (CRDT-aware operation)
+text.splice(unicode_start, unicode_end - unicode_start, new)
+    .map_err(|e| MemoryError::OperationFailed {
+        operation: "replace".to_string(),
+        cause: format!("Splice failed: {}", e),
+    })?;
+
+doc.inner().commit();
+```
+
+**Step 4: Run test to verify it passes**
+
+Run: `cargo nextest run -p pattern-core test_cache_replace_preserves_crdt_operations`
+Expected: PASS
+
+**Step 5: Run full test suite**
+
+Run: `cargo nextest run -p pattern-core`
+Expected: All tests pass
+
+**Step 6: Commit**
+
+```bash
+git add crates/pattern_core/src/memory/cache.rs
+git commit -m "[pattern-core] fix CRDT-aware text replacement in memory cache"
+```
+

+
+## Task 2: Reimplement /list Slash Command
+
+**Files:**
+- Modify: `crates/pattern_cli/src/slash_commands.rs:136-146`
+
+**Context:**
+The `/list` command is stubbed. pattern_db provides `queries::list_agents()`.
+
+**Step 1: Write failing test (manual verification)**
+
+The test here is manual - run `pattern chat` and type `/list` to see the stub message.
+
+**Step 2: Implement the command**
+
+Replace lines 136-146:
+
+```rust
+"/list" => {
+    // Get database pool from context
+    let pool = context.runtime().databases().constellation().pool();
+
+    match pattern_db::queries::list_agents(pool).await {
+        Ok(agents) => {
+            output.section("Agents in Database");
+            if agents.is_empty() {
+                output.status("No agents found in database");
+            } else {
+                for agent in agents {

+                        status_str
+                    ));

+    }
+    Ok(false)
+}
+```
+
+**Step 3: Verify compilation**
+
+Run: `cargo check -p pattern-cli`
+Expected: Compiles without errors

+## Task 3: Reimplement /archival Slash Command
+
+**Files:**
+- Modify: `crates/pattern_cli/src/slash_commands.rs:291-298`
+
+**Context:**
+The `/archival` command needs FTS search. pattern_db provides `fts::search_archival()`.

+## Task 6: Reimplement Debug show-context Command
+
+**Files:**
+- Modify: `crates/pattern_cli/src/commands/debug.rs:485-503`
+
+**Context:**

+## Task 11: Fix Message Content Combination
+
+**Files:**
+- Modify: `crates/pattern_core/src/messages/mod.rs:403-409` and `468-474`
+
+**Context:**
+When combining multiple content items (Text + ToolCalls), the code just takes the first item. We need to properly merge them.
+
+**Step 1: Create a content combination helper**
+
+Add helper function:
+
+```rust
+/// Combine multiple MessageContent items into a single content.
+/// - Multiple Text items: concatenate with newlines
+/// - Text + ToolCalls: create a compound content (if supported) or prioritize ToolCalls
+/// - Multiple ToolCalls: merge into single ToolCalls
+fn combine_content_items(items: Vec<MessageContent>) -> MessageContent {
+    if items.is_empty() {
+        return MessageContent::Text("".to_string());
+    }
+    if items.len() == 1 {
+        return items.into_iter().next().unwrap();
+    }
+
+    let mut texts = Vec::new();
+    let mut tool_calls = Vec::new();
+
+    for item in items {
+        match item {
+            MessageContent::Text(t) => texts.push(t),
+            MessageContent::ToolCalls(calls) => tool_calls.extend(calls),
+            // Other content types passed through as-is if they're the only item
+            other => {
+                // If we have a mix and this is something else, just keep collecting
+                // For now, we'll drop these in the combination
+                tracing::debug!("Dropping non-text/tool-call content in combination: {:?}", other);
+            }
+        }
+    }
+
+    // If we have tool calls, they take precedence (assistant is calling tools)
+    if !tool_calls.is_empty() {
+        // If there's also text, we could potentially include it as a preamble
+        // but for now, return just the tool calls
+        if !texts.is_empty() {
+            tracing::debug!(
+                "Combining text ({} chars) with {} tool calls - text becomes thinking",
+                texts.iter().map(|s| s.len()).sum::<usize>(),
+                tool_calls.len()
+            );

+    }
+
+    // Otherwise, combine texts
+    MessageContent::Text(texts.join("\n"))
+}
+```
+
+**Step 2: Use the helper**
+
+Replace the TODO sections:
+
+```rust
+// Line 403-409

+    agent_id: current_agent.id().to_string(),
+    agent_name: current_agent.name().to_string(),
+    content: response_content, // captured from agent execution
+    metadata: response_metadata,
+};
+
+// Then in the event:
+let _ = tx
+    .send(GroupResponseEvent::Complete {
+        group_id,
+        pattern: "round_robin".to_string(),
+        execution_time: start_time.elapsed(),
+        agent_responses: vec![agent_response], // Include the response
+        state_changes: Some(new_state),
+    })
+    .await;
+```
+
+The specific implementation depends on how responses are captured in each pattern. This task requires reading more context from each file to implement correctly.
+
+**Step 2: Similar fixes for dynamic.rs and sleeptime.rs**
+
+Each pattern needs to capture agent responses during execution and include them in the Complete event.
+
+**Step 3: Commit**
+
+```bash
+git add crates/pattern_core/src/coordination/patterns/*.rs
+git commit -m "[pattern-core] collect actual agent responses in coordination patterns"
+```

+
+## Summary
+
+This plan addresses:
+
+1. **Critical (1 item):**
+   - Memory cache CRDT-aware replace operation
+
+2. **High Priority CLI (8 items):**
+   - `/list`, `/archival`, `/context`, `/search` slash commands
+   - `show-context`, `edit-memory`, `modify-memory`, `context-cleanup` debug commands
+
+3. **High Priority Core (3 items):**
+   - Cross-agent search permissions
+   - Message content combination
+   - Coordination pattern response collection
+
+**Estimated complexity:** Medium-High
+**Dependencies:** pattern_db queries and FTS must be working (they are based on the code review)
+
+---
+
+**Plan complete and saved to `docs/plans/2025-01-01-action-items-core-cli.md`.**
+
+**Two execution options:**
+
+1. **Subagent-Driven (this session)** - I dispatch fresh subagent per task, review between tasks, fast iteration
+
+2. **Parallel Session (separate)** - Open new session with executing-plans, batch execution with checkpoints
+
+**Which approach?**

+# Chunk 1: Database Layer (SQLite Integration)
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Build new SQLite-based database integration in pattern_core alongside existing SurrealDB code.
+
+**Architecture:** New `db_v2` module using pattern_db, compiles independently, no changes to existing db module.
+
+**Tech Stack:** pattern_db, sqlx, SQLite
+
+---
+
+## Philosophy
+
+**DO:**
+- Add new modules that compile
+- Import from pattern_db
+- Write tests for new code
+- Keep everything in source tree
+
+**DON'T:**
+- Remove existing db/ module
+- Try to make old and new interoperate
+- Change existing function signatures
+- Break compilation
+
+---
+
+## Task 1: Add pattern_db Dependency
+
+**Files:**
+- Modify: `crates/pattern_core/Cargo.toml`
+
+**Step 1: Add dependency**
+
+```toml
+[dependencies]
+# ... existing deps ...
+pattern_db = { path = "../pattern_db" }
+```
+
+**Step 2: Verify compilation**
+
+Run: `cargo check -p pattern_core`
+Expected: PASS (pattern_db is already a workspace member)
+
+**Step 3: Commit**
+
+```bash
+git add crates/pattern_core/Cargo.toml
+git commit -m "feat(pattern_core): add pattern_db dependency"
+```
+
+---
+
+## Task 2: Create db_v2 Module Structure
+
+**Files:**
+- Create: `crates/pattern_core/src/db_v2/mod.rs`
+- Create: `crates/pattern_core/src/db_v2/connection.rs`
+- Modify: `crates/pattern_core/src/lib.rs`
+
+**Step 1: Create module directory**
+
+```bash
+mkdir -p crates/pattern_core/src/db_v2
+```
+
+**Step 2: Create mod.rs with re-exports**
+
+```rust
+//! V2 Database layer using SQLite via pattern_db
+//!
+//! This module provides the new database integration that will
+//! eventually replace the SurrealDB-based db module.
+
+mod connection;
+
+pub use connection::*;
+pub use pattern_db::{ConstellationDb, DbError, DbResult};
+pub use pattern_db::models;
+pub use pattern_db::queries;
+```
+
+**Step 3: Create connection.rs skeleton**
+
+```rust
+//! Connection management for constellation databases
+
+use pattern_db::ConstellationDb;
+use std::path::Path;
+
+/// Opens or creates a constellation database at the given path
+pub async fn open_constellation_db(path: impl AsRef<Path>) -> pattern_db::DbResult<ConstellationDb> {
+    ConstellationDb::open(path.as_ref()).await
+}
+
+#[cfg(test)]
+mod tests {
+    use super::*;
+
+    #[tokio::test]
+    async fn test_open_db() {
+        let dir = tempfile::tempdir().unwrap();
+        let db_path = dir.path().join("test.db");
+        let db = open_constellation_db(&db_path).await.unwrap();
+        assert!(db_path.exists());
+    }
+}
+```
+
+**Step 4: Add to lib.rs**
+
+Add this line near other module declarations:
+```rust
+pub mod db_v2;
+```
+
+**Step 5: Verify compilation**
+
+Run: `cargo check -p pattern_core`
+Expected: PASS
+
+**Step 6: Run the test**
+
+Run: `cargo test -p pattern_core db_v2::connection::tests::test_open_db`
+Expected: PASS
+
+**Step 7: Commit**
+
+```bash
+git add crates/pattern_core/src/db_v2/ crates/pattern_core/src/lib.rs
+git commit -m "feat(pattern_core): add db_v2 module with connection management"
+```

+## Chunk 1 Completion Checklist
+
+- [ ] pattern_db added as dependency
+- [ ] db_v2/mod.rs created with re-exports
+- [ ] db_v2/connection.rs with open_constellation_db
+- [ ] db_v2/agents.rs with CRUD operations
+- [ ] db_v2/memory.rs with block + delta operations
+- [ ] db_v2/messages.rs with message operations
+- [ ] db_v2/search.rs with FTS + vector search
+- [ ] All tests pass
+- [ ] Old db/ module untouched and still compiles
+

+
+## Notes for Chunk 2
+
+With db_v2 in place, Chunk 2 (Memory Rework) can:
+- Import from `db_v2` for persistence
+- Create `memory_v2.rs` with Loro integration
+- Use `db_v2::memory::*` for storage operations
+- Build new MemoryStore trait on top

+# Chunk 2: Memory System Rework (Updated)
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Add structured types (Text, List, Map, Log) to the existing memory_v2 cache layer.
+
+**Architecture:** StructuredDocument wraps LoroDoc + BlockSchema, CachedBlock updated to use it.
+
+**Tech Stack:** Loro CRDT 1.10+ (already added), pattern_db, existing memory_v2/cache.rs
+
+**Builds On:** Existing memory_v2 module with MemoryCache, CachedBlock, lazy loading, persistence
+
+---
+
+## Current State (Already Implemented)
+
+```
+memory_v2/
+├── mod.rs      # Exports MemoryCache, types
+├── types.rs    # CachedBlock (holds LoroDoc), BlockType, MemoryError
+└── cache.rs    # MemoryCache with DashMap, lazy load, sync-on-hit, persist
+```
+
+**CachedBlock currently holds:**
+- Raw `LoroDoc`
+- Metadata (id, agent_id, label, description, block_type, permission, etc.)
+- Cache state (last_seq, dirty, last_accessed)
+
+**This plan adds:**
+- BlockSchema enum defining structure (Text, Map, List, Log)
+- StructuredDocument wrapping LoroDoc with typed operations
+- Update CachedBlock to use StructuredDocument
+- Schema-aware operations on MemoryCache
+
+---
+
+## Task 1: Add BlockSchema Types

+## Task 3: Update CachedBlock to Use StructuredDocument
+
+**Files:**
+- Modify: `crates/pattern_core/src/memory_v2/types.rs`
+- Modify: `crates/pattern_core/src/memory_v2/cache.rs`
+
+**Step 1: Update types.rs**
+
+Change CachedBlock to hold StructuredDocument instead of LoroDoc:
+
+```rust
+//! Types for the v2 memory system
+
+use chrono::{DateTime, Utc};
+use loro::VersionVector;
+use crate::memory_v2::StructuredDocument;
+
+/// A cached memory block with its StructuredDocument
+pub struct CachedBlock {
+    /// Block metadata from DB
+    pub id: String,
+    pub agent_id: String,
+    pub label: String,
+    pub description: String,
+    pub block_type: BlockType,
+    pub char_limit: i64,
+    pub permission: pattern_db::models::MemoryPermission,
+
+    /// The structured document (LoroDoc + schema)
+    pub doc: StructuredDocument,
+
+    /// Last sequence number we've seen from DB
+    pub last_seq: i64,
+
+    /// Version at last persist (for delta export)
+    pub last_persisted_version: Option<VersionVector>,
+
+    /// Whether we have unpersisted changes
+    pub dirty: bool,
+
+    /// When this was last accessed (for eviction)
+    pub last_accessed: DateTime<Utc>,
+}
+
+// ... rest of types.rs unchanged ...
+```
+
+**Step 2: Update cache.rs**
+
+Update MemoryCache to:
+1. Load schema from DB (stored in metadata JSON or separate column)
+2. Create StructuredDocument instead of raw LoroDoc
+3. Update persistence to work with StructuredDocument
+
+Key changes in `load_from_db`:
+
+```rust
+async fn load_from_db(&self, agent_id: &str, label: &str) -> MemoryResult<Option<CachedBlock>> {
+    let block = pattern_db::queries::get_block_by_label(self.db.pool(), agent_id, label).await?;
+    let block = match block {
+        Some(b) => b,
+        None => return Ok(None),
+    };
+
+    // Get schema from metadata (default to Text if not set)
+    let schema = block.metadata
+        .as_ref()
+        .and_then(|m| m.get("schema"))
+        .and_then(|s| serde_json::from_value(s.clone()).ok())
+        .unwrap_or_default();
+
+    // Create StructuredDocument
+    let doc = StructuredDocument::new(schema);
+
+    // Import snapshot
+    if !block.loro_snapshot.is_empty() {
+        doc.import(&block.loro_snapshot)?;
+    }
+
+    // Apply updates
+    let (_, updates) = pattern_db::queries::get_checkpoint_and_updates(
+        self.db.pool(), &block.id
+    ).await?;
+    for update in &updates {
+        doc.import(&update.update_blob)?;
+    }
+
+    let last_seq = updates.last().map(|u| u.seq).unwrap_or(block.last_seq);
+    let version = doc.version();
+
+    Ok(Some(CachedBlock {
+        id: block.id,
+        agent_id: block.agent_id,
+        label: block.label,
+        description: block.description,
+        block_type: block.block_type.into(),
+        char_limit: block.char_limit,
+        permission: block.permission,
+        doc,
+        last_seq,
+        last_persisted_version: Some(version),
+        dirty: false,
+        last_accessed: Utc::now(),
+    }))
+}
+```
+
+Update return type of `get()`:
+```rust
+pub async fn get(&self, agent_id: &str, label: &str) -> MemoryResult<Option<&StructuredDocument>>
+```
+
+Or since we're using DashMap, return a guard or clone the doc.
+
+**Step 3: Update tests**
+
+Update tests to work with StructuredDocument API.
+
+**Step 4: Verify and test**
+
+```bash
+cargo check -p pattern_core
+cargo test -p pattern_core memory_v2
+```
+
+**Step 5: Commit**
+
+```bash
+git add crates/pattern_core/src/memory_v2/
+git commit -m "feat(pattern_core): update CachedBlock to use StructuredDocument"

+
+## Task 5: Add Block Creation
+
+**Files:**
+- Modify: `crates/pattern_core/src/memory_v2/cache.rs`
+
+Add method to create new blocks through the cache:
+
+```rust
+impl MemoryCache {
+    /// Create a new memory block
+    pub async fn create_block(
+        &self,
+        agent_id: &str,
+        label: &str,
+        description: &str,
+        block_type: BlockType,
+        schema: BlockSchema,
+        permission: MemoryPermission,
+        char_limit: i64,
+    ) -> MemoryResult<()> {
+        // 1. Create StructuredDocument with schema
+        // 2. Export initial snapshot
+        // 3. Insert into DB via pattern_db::queries::create_block
+        // 4. Add to cache
+    }
+}
+```
+
+---
+
+## Completion Checklist
+
+- [ ] `memory_v2/schema.rs` with BlockSchema, FieldDef, templates
+- [ ] `memory_v2/document.rs` with StructuredDocument
+- [ ] CachedBlock updated to use StructuredDocument
+- [ ] MemoryCache loads schema from DB
+- [ ] High-level operations (get_text, set_field, append_to_list, etc.)
+- [ ] Block creation through cache
+- [ ] All tests pass
+- [ ] Old memory.rs untouched
+
+---
+
+## Notes for Chunk 2.5
+
+With StructuredDocument in place, Chunk 2.5 (Context Rework) can:
+- Use `doc.render()` for context-ready output
+- Leverage schema info for system prompt hints
+- Log blocks automatically limit display via schema
+
+---
+
+## Migration Notes
+
+- Existing blocks without schema metadata default to `BlockSchema::Text`
+- Schema stored in `metadata` JSON column: `{"schema": {...}}`
+- Can add schema to existing blocks by updating metadata

+# Chunk 2: Memory System Rework
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Build new agent-scoped, Loro-backed memory system with **structured types** (Text, List, Map, Tree, Counter) alongside existing DashMap-based system.
+
+**Architecture:** New `memory_v2` module with MemoryStore trait, Loro documents with typed containers, block schemas, SQLite persistence via db_v2.
+
+**Tech Stack:** Loro CRDT 1.10+ (with counter feature), pattern_db, db_v2 module from Chunk 1
+
+**Depends On:** Chunk 1 (db_v2 module exists)
+
+**Design Reference:** `docs/refactoring/v2-structured-memory-sketch.md`
+
+---
+
+## Philosophy
+
+**DO:**
+- Add `memory_v2.rs` alongside `memory.rs`
+- Add `loro` crate dependency
+- Create new MemoryStore trait
+- Build Loro document helpers
+- Keep old memory.rs untouched
+
+**DON'T:**
+- Modify existing memory.rs
+- Change tool implementations yet (Task 7+)
+- Break compilation
+- Try to share types between old and new
+
+---
+
+## Task 1: Add Loro Dependency
+
+**Files:**
+- Modify: `crates/pattern_core/Cargo.toml`
+
+**Step 1: Add loro dependency with counter feature**
+
+```toml
+[dependencies]
+# ... existing deps ...
+loro = { version = "1.10", features = ["counter"] }
+```
+
+The `counter` feature enables `LoroCounter` for numeric tracking (energy levels, counts, etc.).
+
+**Step 2: Verify compilation**
+
+Run: `cargo check -p pattern_core`
+Expected: PASS
+
+**Step 3: Commit**
+
+```bash
+git add crates/pattern_core/Cargo.toml
+git commit -m "feat(pattern_core): add loro CRDT dependency with counter feature"
+```
+
+---
+
+## Task 2: Create Memory V2 Module Structure with Schemas
+
+**Files:**
+- Create: `crates/pattern_core/src/memory_v2/mod.rs`
+- Create: `crates/pattern_core/src/memory_v2/types.rs`
+- Create: `crates/pattern_core/src/memory_v2/schema.rs`
+- Modify: `crates/pattern_core/src/lib.rs`
+
+**Step 1: Create module directory**
+
+```bash
+mkdir -p crates/pattern_core/src/memory_v2
+```
+
+**Step 2: Create types.rs with core types**
+
+```rust
+//! Core types for the v2 memory system
+//!
+//! Key differences from v1:
+//! - Agent-scoped (agent_id) instead of user-scoped (owner_id)
+//! - Loro CRDT documents for versioning
+//! - Explicit block types (Core, Working, Archival, Log)
+//! - Structured schemas (Text, Map, List, Tree, Log)
+//! - Descriptions required (LLM-critical per Letta pattern)

+
+```rust
+//! V2 Memory System
+//!
+//! Agent-scoped, Loro-backed memory with versioning and history.
+//!
+//! # Key Differences from V1
+//!
+//! - **Ownership**: Agent-scoped (`agent_id`) not user-scoped (`owner_id`)
+//! - **Storage**: Loro CRDT documents with SQLite persistence
+//! - **Versioning**: Full history via Loro, time-travel capable
+//! - **No Cache**: SQLite is source of truth, no DashMap
+//! - **Block Types**: Core, Working, Archival, Log
+//! - **Schemas**: Structured types (Map, List, Tree, Counter)
+//! - **Descriptions**: Required for LLM understanding (Letta pattern)
+
+pub mod schema;

+// Placeholder for future modules
+// mod document;  // Loro document operations
+// mod store;     // MemoryStore trait and implementation
+// mod context;   // Context building for LLM calls
+```
+
+**Step 5: Add to lib.rs**
+
+```rust
+pub mod memory_v2;
+```
+
+**Step 6: Verify compilation**
+
+Run: `cargo check -p pattern_core`

+## Task 3: Create Structured Loro Document Helpers
+
+**Files:**
+- Create: `crates/pattern_core/src/memory_v2/document.rs`
+- Modify: `crates/pattern_core/src/memory_v2/mod.rs`
+
+This task creates a `StructuredDocument` wrapper that handles all Loro container types based on block schema.
+
+**Step 1: Create document.rs**
+
+```rust
+//! Loro document operations for structured memory blocks
+//!
+//! Each memory block's content is stored as a Loro document.
+//! The document structure depends on the block's schema:
+//! - Text schema: Single LoroText container
+//! - Map schema: LoroMap with nested containers per field
+//! - List schema: LoroList of items
+//! - Log schema: LoroList with auto-trim
+//!
+//! All documents provide automatic versioning, history, and CRDT merging.

+
+## Task 7: Update pattern_db Queries (if missing)
+
+Before this task, verify pattern_db has these queries. If not, add them:
+
+**Required in pattern_db/src/queries/memory.rs:**
+- `create_shared_block_agent(pool, block_id, agent_id, write_access)`
+- `delete_shared_block_agent(pool, block_id, agent_id)`
+- `list_shared_block_agents(pool, block_id)`
+- `list_agent_shared_blocks(pool, agent_id)`
+- `get_shared_block_agent(pool, block_id, agent_id)`
+
+This may require a separate task to add missing queries to pattern_db.
+
+---
+
+## Chunk 2 Completion Checklist
+
+- [ ] `loro` dependency added (with counter feature)
+- [ ] `memory_v2/types.rs` with core types
+- [ ] `memory_v2/schema.rs` with BlockSchema, FieldDef, templates
+- [ ] `memory_v2/document.rs` with StructuredDocument (Text, Map, List, Log)
+- [ ] `memory_v2/store.rs` with MemoryStore trait + SQLite impl
+  - [ ] Structured operations: set_field, append_to_list, increment_counter, append_log_entry
+  - [ ] JSON text support for set_block_content on structured blocks
+  - [ ] Schema storage in database (schema_json column)
+- [ ] `memory_v2/context.rs` with context builder
+- [ ] `memory_v2/sharing.rs` with shared block support
+- [ ] All tests pass (text + structured operations)
+- [ ] Old `memory.rs` untouched and still compiles
+
+---
+
+## pattern_db Updates Needed
+
+Before Chunk 2 starts, pattern_db needs:
+- [ ] `schema_json` column on memory_blocks table (TEXT, nullable)
+- [ ] Migration to add the column
+
+---
+
+## Notes for Chunk 3
+
+With memory_v2 in place, Chunk 3 (Agent Rework) can:
+- Create `db_agent_v2.rs` using MemoryStore trait
+- Inject SqliteMemoryStore into agent
+- Use MemoryContextBuilder for context building
+- Keep old DatabaseAgent for reference

+# Chunk 2.5: Context & Prompt Rework
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Update context building for structured memory blocks, rich summaries, constellation activity tracking, and system prompt templates.
+
+**Architecture:** New `context_v2` module alongside existing context code, using memory_v2's structured types and MemoryStore trait.
+
+**Important Distinction:**
+- **Memory blocks** (Log type): Agent-managed via memory tools, Loro-backed, stored in memory_blocks table
+- **Constellation activity**: System-level telemetry, NOT a memory block, stored in activity_events table, not manipulable by agents - USING coordination types in `pattern_db/src/models/coordination.rs`
+
+**Tech Stack:** memory_v2 module (from Chunk 2), pattern_db, Loro documents
+
+**Depends On:** Chunk 2 (memory_v2 with StructuredDocument, BlockSchema)
+
+---
+
+## Philosophy
+
+**DO:**
+- Add `context_v2/` module alongside existing context code
+- Build schema-aware context rendering
+- Create structured SummaryBlock for rich archive summaries
+- Implement activity event logging to database
+- Create system prompt templates for agents
+- Keep old context code untouched
+
+**DON'T:**
+- Modify existing context code yet
+- Break compilation
+- Try to share implementations between old and new
+
+---
+
+## As-Built Reconciliation (2025-12-23)
+
+### Key Finding: memory_v2/context.rs Already Exists
+
+There's already a `MemoryContextBuilder` in `memory_v2/context.rs` that handles basic context building:
+- Groups blocks by BlockType (Core, Working, Log)
+- XML-like formatting with descriptions
+- Excludes Archival blocks
+- Token estimation
+
+**Decision:** Keep `context_v2` as a SEPARATE module (not inside memory_v2). This is the correct architecture because:
+1. `memory_v2/context.rs` = simple memory block formatting
+2. `context_v2/` = full context assembly with model limits, activity, summaries
+
+### API Method Name Correction
+
+The plan references `store.get_block_rendered()` but the actual MemoryStore trait uses:
+```rust
+async fn get_rendered_content(&self, agent_id: &str, label: &str) -> MemoryResult<Option<String>>
+```
+
+**Action:** Use `get_rendered_content()` in builder.rs implementations.
+
+### Database Tables Required
+
+Need to create migration `0005_activity_and_summaries.sql` with:
+- `activity_events` table
+- `conversation_summaries` table
+
+**NOTE:** The pattern_db queries (activity.rs, summary.rs) referenced in Task 6 don't exist yet - they must be created first.
+
+### Task Status
+
+- Tasks 1-5: Ready to implement as specified
+- Task 6: Requires creating pattern_db query modules BEFORE the pattern_core code that uses them
+
+---
+
+## Task 1: Create Context V2 Module Structure
+
+**Files:**
+- Create: `crates/pattern_core/src/context_v2/mod.rs`
+- Create: `crates/pattern_core/src/context_v2/types.rs`
+- Modify: `crates/pattern_core/src/lib.rs`
+
+**Step 1: Create module directory**
+
+```bash
+mkdir -p crates/pattern_core/src/context_v2
+```
+
+**Step 2: Create types.rs with context types**
+
+```rust

+//! and rich summaries.

+- Modify: `crates/pattern_db/src/queries/mod.rs`
+- Create: `crates/pattern_db/src/queries/activity.rs`
+- Create: `crates/pattern_db/src/queries/summary.rs`
+
+This task adds the database queries needed by the activity logger and summary store.
+
+**Step 1: Add activity queries**
+
+Create `activity.rs`:
+```rust

+    .fetch_all(pool)
+    .await?;

+}
+```
+
+**Step 2: Add summary queries**
+
+Create `summary.rs`:

+
+**Step 3: Add migrations for new tables**

+# Chunk 3: Agent Rework
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Build new DatabaseAgent using SQLite backend (db_v2) and Loro-backed memory (memory_v2).
+
+**Architecture:** New `db_agent_v2.rs` alongside existing agent, uses MemoryStore trait, ConstellationDb for persistence.
+
+**Tech Stack:** db_v2, memory_v2, pattern_db
+
+**Depends On:** Chunk 1 (db_v2), Chunk 2 (memory_v2)
+
+---
+
+## Philosophy
+
+**DO:**
+- Create `db_agent_v2.rs` alongside `db_agent.rs`
+- Use dependency injection for MemoryStore
+- Keep existing Agent trait
+- Build incrementally, testing each piece
+
+**DON'T:**
+- Modify existing db_agent.rs
+- Change the Agent trait interface
+- Remove any existing code
+- Try to make v1 and v2 agents interoperate
+
+---
+
+## As-Built Reconciliation (2025-12-23)
+
+### Naming Difference: MemoryCache not SqliteMemoryStore
+
+The plan references `SqliteMemoryStore` but the actual implementation is `MemoryCache` in `memory_v2/cache.rs`. Same functionality, different name.
+
+**Action:** Replace all `SqliteMemoryStore` references with `MemoryCache`.
+
+### API Pattern Difference: Document-Based Operations
+
+The plan assumes direct methods on MemoryStore trait:
+```rust
+// Plan assumes:
+store.set_block_content(agent_id, label, content, source)
+store.append_block_content(agent_id, label, content, source)
+```
+
+But actual MemoryStore trait requires:
+```rust
+// Actual pattern:
+let doc = store.get_block(agent_id, label).await?;
+doc.set_text(content)?;
+store.mark_dirty(agent_id, label);
+store.persist_block(agent_id, label).await?;
+```
+
+**Action:** Task 3 (AgentHandleV2) convenience methods must follow the actual pattern.
+
+### Task 4 (MessageManagerV2): REMOVE ENTIRELY
+
+MessageManagerV2 is over-engineered. It's just a struct holding `(agent_id, db)` and wrapping query calls. That adds no value.
+
+**Decision:** Delete Task 4. Agents should call `pattern_db::queries::` directly:
+- `queries::get_messages(pool, agent_id, limit)`
+- `queries::create_message(pool, &msg)`
+- `queries::archive_messages(pool, agent_id, before_position)`
+- etc.
+
+### Use Snowflake IDs (NOT Timestamps)
+
+The plan shows `generate_position()` using timestamp hex. That's wrong - the system already uses Snowflake IDs for message ordering.
+
+**Action:** Use existing Snowflake ID generation for message positions.
+
+### db_v2: What SHOULD Be There
+
+The gap isn't query wrappers - it's the bridge between:
+- `EmbeddingProvider` (pattern_core) - generates embeddings from text
+- `pattern_db::vector` - stores and searches embeddings
+
+**What db_v2 should provide:**
+```rust
+/// Embed content and store it
+pub async fn embed_and_store<E: EmbeddingProvider>(
+    db: &ConstellationDb,
+    embedder: &E,
+    content_type: ContentType,
+    content_id: &str,
+    text: &str,
+) -> DbResult<i64>
+
+/// Search with text query (embeds it first)
+pub async fn semantic_search<E: EmbeddingProvider>(
+    db: &ConstellationDb,
+    embedder: &E,
+    query: &str,
+    content_type: Option<ContentType>,
+    limit: i64,
+) -> DbResult<Vec<VectorSearchResult>>
+```
+
+This is substantive - it combines two layers. Add this when needed, not preemptively.
+
+### Task 6: Missing BlockSchema Parameter
+
+The `create_block()` calls in Task 6 are missing the `schema: BlockSchema` parameter.
+
+**Correct signature:**
+```rust
+async fn create_block(
+    &self,
+    agent_id: &str,
+    label: &str,
+    description: &str,
+    block_type: BlockType,
+    schema: BlockSchema,  // <- Add this!
+    char_limit: usize,
+) -> MemoryResult<String>
+```
+
+**Action:** Add `BlockSchema::Text` as the schema parameter in all create_block calls.
+
+### ChangeSource Type
+
+The plan references `ChangeSource::Agent(agent_id)` but this type doesn't exist in memory_v2.
+
+**Decision:** Add ChangeSource to `memory_v2/types.rs`:
+```rust
+/// Source of a memory change (for audit trails)
+#[derive(Debug, Clone, Serialize, Deserialize)]
+pub enum ChangeSource {
+    /// Change made by an agent
+    Agent(String),
+    /// Change made by a human/partner
+    Human(String),
+    /// Change made by system (e.g., compression)
+    System,
+    /// Change from external integration
+    Integration(String),
+}
+```
+
+This enables tracking who/what modified memory blocks for debugging and audit purposes.
+
+### Task Order
+
+Recommended execution order:
+1. **Pre-req:** ✅ ChangeSource added to memory_v2/types.rs
+2. Task 1: Module structure (update SqliteMemoryStore → MemoryCache)
+3. Task 2: AgentRecordV2 (verify against pattern_db models)
+4. Task 6: DefaultBlocks (add BlockSchema parameter)
+5. Task 3: AgentHandleV2 (rewrite with correct API pattern)
+6. ~~Task 4: MessageManagerV2~~ **REMOVED** - use queries directly
+7. Task 5: Full implementation (includes direct query calls for messages)

+- `Agent::handle()` - Return AgentHandleV2
+- Context building using MemoryContextBuilder
+- Message persistence using MessageManagerV2

+# Chunk 3: Agent Architecture Rework (Consolidated)
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Rework the agent architecture with clean separation of concerns: slim Agent trait, Runtime for actions, ContextBuilder for assembly, separate stores for memory and messages.
+
+**Depends On:** Chunk 1 (pattern_db), Chunk 2 (memory_v2)
+
+**Incorporates:** Remaining work from Chunk 2.5 (context_v2)
+

+
+### Key Principles
+
+1. **Agent is slim** - just identity + process loop + state
+2. **Runtime does things** - tool execution, message sending, permission checks
+3. **ContextBuilder reads things** - assembles model requests from current state
+4. **Stores are separate** - MemoryStore (blocks) vs MessageStore (history)
+5. **Memory access via tools** - agents don't directly touch memory, tools do
+6. **Embeddings at db layer** - async background jobs, not blocking writes
+7. **Stream-first processing** - `process()` returns Stream, collector helper for Response
+
+### Store Scoping
+
+- **MemoryStore** - **Shared** across agents. Agent-agnostic, `agent_id` is just a parameter.
+  Multiple agents can use the same MemoryStore instance.
+
+- **MessageStore** - **Per-agent**. Messages are provider-specific in practice (thinking blocks,
+  tool call formats, etc.). Each agent gets its own MessageStore instance configured for its
+  model provider.
+
+---
+
+## Component Specifications
+
+### 1. Agent Trait (Slim)
+
+```rust
+#[async_trait]
+pub trait Agent: Send + Sync + Debug {
+    fn id(&self) -> AgentId;
+    fn name(&self) -> &str;
+    fn runtime(&self) -> &AgentRuntime;
+
+    /// Process a message, streaming response events
+    async fn process(
+        self: Arc<Self>,
+        message: Message,
+    ) -> Result<Box<dyn Stream<Item = ResponseEvent> + Send + Unpin>>;
+
+    /// Current agent state
+    async fn state(&self) -> AgentState;
+    async fn set_state(&self, state: AgentState) -> Result<()>;
+}
+
+// Collector helper
+pub async fn collect_response(
+    stream: impl Stream<Item = ResponseEvent>,
+) -> Result<Response> {
+    // Collects stream into final Response
+}
+```
+
+**What's removed from old Agent trait:**
+- `get_memory()`, `update_memory()`, `set_memory()` → via tools through Runtime
+- `share_memory_with()`, `get_shared_memories()` → via MemoryStore
+- `execute_tool()` → moved to Runtime
+- `available_tools()` → in ToolRegistry
+- `system_prompt()` → handled by ContextBuilder
+- `register_endpoint()`, `set_default_user_endpoint()` → on Runtime
+- `handle()` → replaced by `runtime()`
+
+### 2. AgentRuntime (Doing)
+
+```rust
+pub struct AgentRuntime {
+    agent_id: AgentId,
+    agent_name: String,
+
+    // Stores
+    memory: Arc<dyn MemoryStore>,
+    messages: Arc<MessageStore>,
+
+    // Execution
+    tools: Arc<ToolRegistry>,
+    permissions: PermissionBroker,
+    router: AgentMessageRouter,
+
+    // Model
+    model: Arc<dyn ModelProvider>,
+
+    // Database
+    pool: SqlitePool,
+}
+
+impl AgentRuntime {
+    // Tool execution with permission arbitration
+    pub async fn execute_tool(&self, call: &ToolCall) -> Result<ToolResponse>;
+
+    // Message operations
+    pub async fn store_message(&self, message: &Message) -> Result<()>;
+    pub async fn send_message(&self, target: MessageTarget, content: &str) -> Result<()>;
+
+    // Endpoint management
+    pub async fn register_endpoint(&self, name: &str, endpoint: Arc<dyn MessageEndpoint>);
+    pub async fn set_default_endpoint(&self, endpoint: Arc<dyn MessageEndpoint>);
+
+    // Context building (delegates to ContextBuilder)
+    pub async fn build_context(&self, config: &ContextConfig) -> Result<MemoryContext>;
+
+    // Search (delegates to db_v2)
+    pub async fn search(&self, query: &str, options: SearchOptions) -> Result<Vec<SearchResult>>;
+}
+```
+
+### 3. ContextBuilder (Reading)
+
+```rust
+pub struct ContextBuilder<'a> {
+    memory: &'a dyn MemoryStore,
+    messages: &'a MessageStore,
+    tools: &'a ToolRegistry,
+    config: &'a ContextConfig,
+}
+
+impl<'a> ContextBuilder<'a> {
+    pub fn new(
+        memory: &'a dyn MemoryStore,
+        messages: &'a MessageStore,
+        tools: &'a ToolRegistry,
+        config: &'a ContextConfig,
+    ) -> Self;
+
+    /// Build complete context for model request
+    pub async fn build(&self) -> Result<MemoryContext>;
+
+    /// Build with specific model adjustments
+    pub async fn build_for_model(&self, model: &ModelInfo) -> Result<MemoryContext>;
+}
+
+
+```
+
+**ContextBuilder responsibilities:**
+- Read memory blocks (core, working) for system prompt
+- Read message history, apply compression if needed
+- Read tool definitions and rules
+- Model-specific formatting (Anthropic vs Gemini vs OpenAI)
+- Cache optimization (stable prefix, variable suffix)
+- Include summaries at top of context window
+
+### 4. MessageStore
+
+```rust
+pub struct MessageStore {
+    pool: SqlitePool,
+    agent_id: String,
+}
+
+impl MessageStore {
+    pub async fn get_recent(&self, limit: usize) -> Result<Vec<Message>>;
+    pub async fn get_all(&self, limit: usize) -> Result<Vec<Message>>;
+    pub async fn store(&self, message: &Message) -> Result<()>;
+    pub async fn archive_before(&self, position: SnowflakePosition) -> Result<u64>;
+
+    // Batch operations
+    pub async fn get_batch(&self, batch_id: &str) -> Result<Vec<Message>>;
+    pub async fn current_batch(&self) -> Result<Option<String>>;
+
+    // Summaries
+    pub async fn get_summary(&self) -> Result<Option<AgentSummary>>;
+    pub async fn upsert_summary(&self, summary: &AgentSummary) -> Result<()>;
+
+    // Activity (uses existing coordination queries)
+    pub async fn log_activity(&self, event: ActivityEvent) -> Result<()>;
+    pub async fn recent_activity(&self, limit: usize) -> Result<Vec<ActivityEvent>>;
+}
+```
+
+### 5. Search & Embedding Layer (db_v2)
+
+db_v2 wraps pattern_db and adds embedding logic. Leverages `pattern_db::search::HybridSearchBuilder`.
+
+```rust
+// In crates/pattern_core/src/db_v2/mod.rs
+
+/// Database layer with embedding support
+pub struct ConstellationDb {
+    pool: SqlitePool,
+    embedder: Option<Arc<dyn EmbeddingProvider>>,
+    embed_tx: Option<mpsc::Sender<EmbedJob>>,  // For background embedding
+}
+
+impl ConstellationDb {
+    /// Create with embedding support
+    pub fn with_embedder(pool: SqlitePool, embedder: Arc<dyn EmbeddingProvider>) -> Self;
+
+    /// Unified search - uses pattern_db::search::HybridSearchBuilder
+    /// If embedder configured and mode requires it, embeds query first
+    pub async fn search(&self, query: &str, options: SearchOptions) -> DbResult<Vec<SearchResult>> {
+        let mut builder = pattern_db::search::search(&self.pool)
+            .text(query)
+            .filter(options.filter)
+            .limit(options.limit)
+            .mode(options.mode);
+
+        // If vector/hybrid requested and we have embedder, embed query
+        if options.mode.needs_embedding() {
+            if let Some(embedder) = &self.embedder {
+                let embedding = embedder.embed_query(query).await?;
+                builder = builder.embedding(embedding);
+            }
+            // No embedder: gracefully fall back to FTS
+        }
+
+        builder.execute().await
+    }
+
+    /// Queue content for background embedding (non-blocking)
+    pub fn queue_embedding(&self, content_type: ContentType, content_id: &str, text: &str);
+}
+```
+
+**Embedding flow:**
+- **Search:** Single `search()` method, mode determines behavior (FTS/Vector/Hybrid/Auto)
+- **Content writes:** `queue_embedding()` fires event, background task embeds and stores
+- **No embedder:** All modes gracefully fall back to FTS
+
+### 6. Memory Search in memory_v2
+
+Expose pattern_db search capabilities:
+
+```rust
+// In memory_v2/store.rs
+
+pub trait MemoryStore: Send + Sync {
+    // ... existing block operations ...
+
+    /// Search memory (FTS, vector, or hybrid)
+    async fn search(
+        &self,
+        agent_id: &str,
+        query: &str,
+        options: SearchOptions,
+    ) -> MemoryResult<Vec<SearchResult>>;
+}
+
+pub struct SearchOptions {
+    pub mode: SearchMode,  // Fts, Vector, Hybrid, Auto
+    pub content_types: Vec<SearchContentType>,  // Blocks, Archival, Messages
+    pub limit: usize,
+}
+
+pub enum SearchMode {
+    Fts,
+    Vector,  // Returns error if embeddings not configured
+    Hybrid,
+    Auto,    // FTS if no embedder, Hybrid if available
+}
+```
+
+---
+
+## Task Breakdown
+
+### Phase A: Foundation Types
+
+**Task A1: Add SearchOptions to memory_v2**
+- Add `SearchOptions`, `SearchMode` types to `memory_v2/types.rs`
+- Add `search()` method to `MemoryStore` trait

+
+**Task A2: Add MessageStore**
+- Create `crates/pattern_core/src/messages/store.rs`
+- Thin wrapper around `pattern_db::queries::messages`
+- Include summary operations (uses coordination queries)
+- Include activity logging
+
+**Task A3: Update context_v2 types**
+- Finalize `ContextConfig` in context_v2/types.rs
+- Add `MemoryContext` output type

+- Remove unnecessary `ToolDescription` types (use ToolRegistry directly)
+
+### Phase B: ContextBuilder
+
+**Task B1: Create ContextBuilder**
+- `crates/pattern_core/src/context_v2/builder.rs`

+
+**Task C2: Port MessageRouter**
+- Update to use pattern_db queries (not SurrealDB)
+- Keep MessageEndpoint trait unchanged
+- Move endpoint registration to Runtime
+
+**Task C3: Port tool execution**
+- Move from AgentContext to Runtime
+- Permission broker integration
+- Memory tools call MemoryStore via Runtime
+
+### Phase D: Agent Trait Rework
+
+**Task D1: Define slim Agent trait**
+- `crates/pattern_core/src/agent/trait.rs` (or update mod.rs)
+- Just id, name, state, process(), runtime()
+- Stream-based processing
+
+**Task D2: Add AgentExt and collector**
+- `process_to_response()` helper
+- Stream collecting utilities
+
+**Task D3: Implement DatabaseAgentV2**
+- `crates/pattern_core/src/agent/impls/db_agent_v2.rs`
+- Uses new Runtime, ContextBuilder
+- Implements slim Agent trait
+
+### Phase E: Integration

+- Search (FTS working, vector errors gracefully)
+
+### Phase F: Cleanup (Later)
+
+**Task F1: Remove old agent code**
+- Delete `db_agent.rs` when v2 is stable
+- Delete `context/state.rs` AgentContext/AgentHandle
+- Remove SurrealDB dependencies
+
+---
+
+## Migration Mapping
+
+| Old Location | New Location | Notes |
+|-------------|--------------|-------|
+| `Agent` trait (17+ methods) | `Agent` trait (5 methods) | Slim down |
+| `AgentHandle` | `AgentRuntime` | Runtime does things |
+| `AgentContext` | Split: Runtime + ContextBuilder | Separate concerns |
+| `context/compression.rs` | `context_v2/builder.rs` | Integrated |
+| `context/state.rs` search methods | `MemoryStore::search()` | Via trait |
+| `message_router.rs` SurrealDB queries | pattern_db queries | DB swap |
+| `message_queue.rs` Entity | pattern_db models | No macro |
+| `db_agent.rs` | `db_agent_v2.rs` | New implementation |
+
+---
+
+## Execution Order
+
+Recommended sequence:
+1. **A1-A3** in parallel (foundation types)
+2. **B1** (ContextBuilder core)
+3. **B2-B3** (ContextBuilder model-aware + compression)
+4. **C1** (AgentRuntime core)
+5. **C2-C3** (Runtime: router + tools)
+6. **D1-D2** (Agent trait)
+7. **D3** (DatabaseAgentV2)
+8. **E1-E4** (Integration)
+9. **F1** (Cleanup - later, after testing)
+
+---
+
+## Success Criteria
+
+- [ ] `cargo check -p pattern_core` passes
+- [ ] `cargo test -p pattern_core` passes
+- [ ] Agent processes messages with new architecture
+- [ ] Tools execute through Runtime with permission checks
+- [ ] Memory operations work via tools
+- [ ] FTS search works, vector search returns graceful error
+- [ ] Message history persists correctly
+- [ ] Context building produces valid model requests
+- [ ] Heartbeat processor works with new Agent trait
+- [ ] Old code remains compilable (parallel implementation)
+
+---
+
+## Design Decisions
+
+1. **Naming:** `AgentRuntime` ✓
+
+2. **ToolRegistry scope:** Variable. Generally per-agent, but some tools need shared state
+   (data sources, etc.). Option to create multiple agents with a totally shared ToolRegistry.
+
+3. **Embedder injection:** At db_v2 layer. This is where we diverge from using pattern_db
+   query methods directly - db_v2 wraps pattern_db and adds embedding logic:
+   - **Search queries:** Blocking - need embedding before search can proceed
+   - **Messages/memory blocks:** Non-blocking, event-triggered background jobs
+
+4. **Stream type:** `Box<dyn Stream + Send + Unpin>` for trait object compatibility.

+## Completion Checklist
+
+- [ ] Loro dependency added
+- [ ] memory_v2/types.rs with CachedBlock, BlockType, MemoryError
+- [ ] memory_v2/cache.rs with MemoryCache, lazy loading, delta persistence
+- [ ] memory_v2/ops.rs with get_text, set_text, append_text, replace_text
+- [ ] All tests pass
+- [ ] Old memory.rs untouched
+
+---
+
+## Notes
+
+This is the foundation. Future work:
+- Structured block schemas (Map, List, Log types)
+- Block creation through cache
+- Consolidation (snapshot updates when too many deltas)
+- Eviction policies (LRU when cache gets too big)
+- Sync with updates from other sources

+# Phase B: ContextBuilder Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Create a new ContextBuilder in context_v2 that reads from MemoryStore, MessageStore, and ToolRegistry to produce a `Request` ready for model calls.
+
+**Architecture:** Read-only builder pattern. Receives references to stores and registry, builds system prompt from memory blocks, handles message history with compression, produces model-ready `Request` directly (no intermediate MemoryContext).
+
+**Tech Stack:** Rust async, pattern_db (SQLite), existing compression.rs logic
+
+**Dependencies:** Phase A complete (SearchOptions, MessageStore, context_v2 types)
+
+**Output Type:** `crate::message::Request` which is:
+```rust
+pub struct Request {
+    pub system: Option<Vec<String>>,
+    pub messages: Vec<Message>,
+    pub tools: Option<Vec<genai::chat::Tool>>,
+}
+```
+
+---
+
+## Task B1: Create ContextBuilder Core
+
+**Files:**
+- Create: `crates/pattern_core/src/context_v2/builder.rs`
+- Modify: `crates/pattern_core/src/context_v2/mod.rs`
+
+### Step 1: Write failing test for ContextBuilder
+
+```rust

+        let memory = MockMemoryStore::new();
+        memory.add_block("persona", "You are a helpful assistant.", BlockType::Core);
+
+        let config = ContextConfig::default();
+        let builder = ContextBuilder::new(&memory, &config);
+
+        let request = builder.build().await.unwrap();

+
+    // Gemini requires first message to be user - should have been adjusted
+    assert_eq!(request.messages.first().unwrap().role, ChatRole::User);
+}
+```
+
+### Step 2: Add ModelInfo to builder
+
+```rust

+### Step 3: Add ModelInfo struct
+
+```rust

+
+### Step 4: Add Gemini message validation
+
+```rust

+
+        // Remove empty messages

+    }
+}
+```
+

+    assert!(request.messages.len() <= 200);
+}
+```
+
+### Step 2: Add compression fields to ContextConfig
+
+```rust
+// Add to existing ContextConfig in types.rs
+
+#[derive(Debug, Clone)]
+pub struct ContextConfig {
+    // Existing fields:
+    pub default_limits: ModelContextLimits,
+    pub model_overrides: HashMap<String, ModelContextLimits>,
+    pub include_descriptions: bool,
+    pub include_schemas: bool,
+    pub activity_entries_limit: usize,
+
+    // New compression fields:
+    /// Compression strategy when context exceeds limits
+    pub compression_strategy: CompressionStrategy,
+    /// Hard cap on messages (safety limit, regardless of tokens)
+    pub max_messages_cap: usize,
+}
+
+// Update Default impl to include new fields
+impl Default for ContextConfig {
+    fn default() -> Self {
+        Self {
+            default_limits: ModelContextLimits::large(),
+            model_overrides: HashMap::new(),
+            include_descriptions: true,
+            include_schemas: false,
+            activity_entries_limit: 15,
+            // New defaults:
+            compression_strategy: CompressionStrategy::Truncate { keep_recent: 100 },
+            max_messages_cap: 500, // Safety cap
+        }
+    }
+}
+```
+
+**Note:** Compression is primarily driven by `ModelContextLimits::history_tokens` (model-specific), with `max_messages_cap` as a global safety limit.
+
+### Step 3: Port compression logic to builder
+
+```rust
+impl<'a> ContextBuilder<'a> {
+    /// Build the complete Request (updated with compression)
+    pub async fn build(self) -> Result<Request, CoreError> {

+        let mut messages = if let Some(msg_store) = self.messages {
+            // Fetch up to safety cap
+            msg_store.get_all(self.config.max_messages_cap).await?
+        } else {

+
+        // Get model-specific limits
+        let limits = self.config.limits_for_model(

+        messages = self.compress_to_token_limit(messages, limits.history_tokens);

+
+        Ok(Request {

+
+        // Apply compression strategy

+            CompressionStrategy::Truncate { keep_recent } => {
+                // Remove oldest messages until under limit, keeping at least keep_recent
+                while total_tokens > max_tokens && messages.len() > *keep_recent {

+            }

+```
+
+### Step 4: Add ModelProvider for summarization (optional extension)
+
+```rust
+impl<'a> ContextBuilder<'a> {
+    /// Add model provider for summarization-based compression
+    pub fn with_model_provider(mut self, provider: Arc<dyn ModelProvider>) -> Self {
+        self.model_provider = Some(provider);
+        self
+    }
+
+    /// Summarize messages using model
+    async fn summarize_messages(
+        &self,
+        messages: &[Message],
+        prompt: &str,
+    ) -> Result<String, CoreError> {
+        let Some(provider) = &self.model_provider else {
+            return Err(CoreError::ConfigurationError {
+                field: "model_provider".into(),
+                message: "Model provider required for summarization".into(),
+            });
+        };
+
+        // Build summarization request
+        // ... implementation using provider.complete() ...
+
+        todo!("Implement summarization request")
+    }
+}
+```
+
+### Step 5: Commit
+
+```bash
+git add crates/pattern_core/src/context_v2/builder.rs crates/pattern_core/src/context_v2/types.rs
+git commit -m "feat(context_v2): add compression integration to ContextBuilder"
+```
+
+---
+
+## Success Criteria
+
+- [ ] `cargo check -p pattern-core` passes
+- [ ] `cargo test -p pattern-core context_v2` passes
+- [ ] ContextBuilder reads from MemoryStore trait
+- [ ] ContextBuilder reads from MessageStore
+- [ ] ContextBuilder reads from ToolRegistry
+- [ ] ContextBuilder returns `Request` directly (not intermediate type)
+- [ ] System prompt includes memory blocks
+- [ ] Gemini message validation applied (first message is user)
+- [ ] Compression driven by `history_tokens` limit (model-specific)
+- [ ] Safety cap `max_messages_cap` respected
+
+---
+
+## Notes
+
+- ContextBuilder is **read-only** - it doesn't mutate stores
+- ContextBuilder returns `Request` directly - no intermediate MemoryContext needed
+- Compression is **in-memory** for context building - actual archival happens elsewhere
+- Compression is **token-driven** using `ModelContextLimits::history_tokens`
+- Token estimation is rough (4 chars/token) - can be refined later or use model's tokenizer

+# Phase C: AgentRuntime Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Create AgentRuntime that holds all agent dependencies (stores, tools, permissions, router, model) and handles tool execution, message sending, and permission checks.
+
+**Architecture:** Runtime is the "doing" layer - it executes tools, sends messages, stores messages, and manages permissions. Agent trait delegates all actions to Runtime.
+
+**Tech Stack:** Rust async, pattern_db (SQLite), tokio channels for permissions
+
+**Dependencies:** Phase A complete (MemoryStore, MessageStore), Phase B complete (ContextBuilder)
+
+---
+

+## Task C1: Create AgentRuntime Struct
+
+**Files:**
+- Create: `crates/pattern_core/src/runtime/mod.rs`
+- Create: `crates/pattern_core/src/runtime/types.rs`
+- Modify: `crates/pattern_core/src/lib.rs`
+
+### Step 1: Write failing test for AgentRuntime construction
+
+```rust
+// In crates/pattern_core/src/runtime/mod.rs
+
+#[cfg(test)]
+mod tests {
+    use super::*;
+
+    #[tokio::test]
+    async fn test_runtime_construction() {
+        let pool = test_pool().await;
+        let memory = Arc::new(MockMemoryStore::new());
+        let messages = MessageStore::new(pool.clone(), "test_agent");
+        let tools = ToolRegistry::new();
+
+        let runtime = AgentRuntime::builder()
+            .agent_id("test_agent")
+            .memory(memory)
+            .messages(messages)
+            .tools(tools)
+            .pool(pool)
+            .build()
+            .unwrap();
+
+        assert_eq!(runtime.agent_id(), "test_agent");
+    }
+}
+```
+
+### Step 2: Run test to verify it fails
+
+Run: `cargo test -p pattern-core runtime::tests::test_runtime_construction`
+Expected: FAIL - module doesn't exist

+
+**Files:**
+- Modify: `crates/pattern_core/src/runtime/mod.rs`

+
+```rust
+#[tokio::test]
+async fn test_runtime_execute_tool() {
+    let runtime = create_test_runtime().await;
+
+    // Register a simple echo tool

+    };
+
+    let response = runtime.execute_tool(&call).await.unwrap();
+
+    assert_eq!(response.content, "hello");
+}
+```
+
+### Step 2: Implement execute_tool
+
+```rust

+
+### Step 4: Add pattern_db queries for agent/group lookup
+
+```rust

+           FROM agents WHERE name = ?"#,
+        name
+    )
+    .fetch_optional(pool)
+    .await?;
+    Ok(agent)
+}

+        name
+    )
+    .fetch_optional(pool)
+    .await?;
+    Ok(group)
+}
+```
+
+### Step 5: Commit
+
+```bash
+git add crates/pattern_core/src/runtime/router.rs crates/pattern_core/src/error.rs crates/pattern_db/src/queries/
+git commit -m "feat(runtime): port MessageRouter to pattern_db"
+```
+

+
+## Task C3: Add Message Operations and Context Building
+
+**Files:**
+- Modify: `crates/pattern_core/src/runtime/mod.rs`
+
+### Step 1: Write failing test for store_message
+
+```rust
+#[tokio::test]
+async fn test_runtime_store_message() {
+    let runtime = create_test_runtime().await;
+
+    let message = Message::user("Hello, world!");
+    runtime.store_message(&message).await.unwrap();
+
+    let recent = runtime.messages().get_recent(1).await.unwrap();
+    assert_eq!(recent.len(), 1);
+    assert_eq!(recent[0].content.to_string(), "Hello, world!");
+}
+```
+
+### Step 2: Add message operations to Runtime
+
+```rust
+impl AgentRuntime {
+    /// Store a message
+    pub async fn store_message(&self, message: &Message) -> Result<(), CoreError> {
+        self.messages.store(message).await
+    }
+
+    /// Get recent messages
+    pub async fn get_recent_messages(&self, limit: usize) -> Result<Vec<Message>, CoreError> {
+        self.messages.get_recent(limit).await
+    }
+
+    /// Get message store (for direct access)
+    pub fn messages(&self) -> &MessageStore {
+        &self.messages
+    }
+
+    /// Build context for model request
+    pub async fn build_request(&self) -> Result<Request, CoreError> {
+        let builder = ContextBuilder::new(self.memory.as_ref(), &self.config.context_config)
+            .for_agent(&self.agent_id.to_string())
+            .with_messages(&self.messages)
+            .with_tools(&self.tools);
+
+        builder.build().await
+    }
+
+    /// Send a message via router
+    pub async fn send_message(
+        &self,
+        target: MessageTarget,
+        content: impl Into<String>,
+        metadata: Option<Value>,
+    ) -> Result<Option<String>, CoreError> {
+        let origin = MessageOrigin::Agent {
+            agent_id: self.agent_id.clone(),
+            name: self.agent_name.clone(),
+            reason: "agent initiated".into(),
+        };
+
+        self.router.send_message(target, content.into(), metadata, Some(origin)).await
+    }
+}
+```
+
+### Step 3: Add search delegation
+
+```rust
+impl AgentRuntime {
+    /// Search across memory and messages
+    pub async fn search(
+        &self,
+        query: &str,
+        options: crate::memory_v2::SearchOptions,
+    ) -> Result<Vec<crate::memory_v2::MemorySearchResult>, CoreError> {
+        self.memory.search(&self.agent_id.to_string(), query, options)
+            .await
+            .map_err(CoreError::MemoryError)
+    }
+}
+```
+
+### Step 4: Commit
+
+```bash
+git add crates/pattern_core/src/runtime/mod.rs
+git commit -m "feat(runtime): add message operations and context building"
+```
+
+---
+
+## Success Criteria
+
+- [ ] `cargo check -p pattern-core` passes
+- [ ] `cargo test -p pattern-core runtime` passes
+- [ ] AgentRuntime builds with all required dependencies
+- [ ] Tool execution works with permission checks
+- [ ] MessageRouter uses pattern_db (not SurrealDB)
+- [ ] Agent/group name resolution works
+- [ ] Anti-loop protection for agent-to-agent messages
+- [ ] Message storage delegates to MessageStore
+- [ ] `build_request()` delegates to ContextBuilder, returns `Request`
+- [ ] Search delegates to MemoryStore
+
+---
+
+## Notes
+
+- **Router migration:** The key change is replacing SurrealDB queries with pattern_db queries
+- **Permission broker:** Kept as-is (already uses tokio channels, not DB)
+- **Endpoints:** Interface unchanged, implementations stay in consumers (discord, cli, etc.)
+- **Cooldown:** 30 seconds between rapid agent-to-agent messages (anti-loop)
+- **Error variants:** Added specific errors for better debugging

+# Phase D: Slim Agent Trait Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Define a dramatically slimmed Agent trait (6 methods vs current 17+) that delegates all "doing" to AgentRuntime and all "reading" to ContextBuilder.
+
+**Architecture:** The new `AgentV2` trait is identity + process loop + state only. Memory operations, tool execution, endpoint registration all go through `AgentRuntime`. Context building goes through `ContextBuilder`. Memory access for agents is via tools, not direct trait methods.
+
+**Tech Stack:** Rust async_trait, tokio-stream, pattern_core runtime/context_v2 modules
+
+**Parallel Development:** Define as `AgentV2` in `agent_v2` module to avoid conflicts with existing `Agent` trait. Swap later when v2 is stable.
+
+---
+
+## Architecture Comparison
+
+### Current Agent Trait (17+ methods - TOO FAT)
+```rust
+trait Agent {
+    fn id(&self) -> AgentId;
+    fn name(&self) -> String;
+    fn agent_type(&self) -> AgentType;
+    async fn handle(&self) -> AgentHandle;
+    async fn last_active(&self) -> Option<DateTime>;
+    async fn process_message(self: Arc<Self>, message: Message) -> Result<Response>;
+    async fn process_message_stream(...) -> Result<Box<dyn Stream<...>>>;
+    async fn get_memory(&self, key: &str) -> Result<Option<MemoryBlock>>;
+    async fn update_memory(&self, key: &str, memory: MemoryBlock) -> Result<()>;
+    async fn set_memory(&self, key: &str, value: String) -> Result<()>;
+    async fn list_memory_keys(&self) -> Result<Vec<CompactString>>;
+    async fn share_memory_with(...) -> Result<()>;
+    async fn get_shared_memories(&self) -> Result<Vec<...>>;
+    async fn system_prompt(&self) -> Vec<String>;
+    async fn available_tools(&self) -> Vec<Box<dyn DynamicTool>>;
+    async fn state(&self) -> (AgentState, Option<Receiver<AgentState>>);
+    async fn set_state(&self, state: AgentState) -> Result<()>;
+    async fn register_endpoint(...) -> Result<()>;
+    async fn set_default_user_endpoint(...) -> Result<()>;
+    async fn execute_tool(...) -> Result<serde_json::Value>;
+}
+```
+
+### New AgentV2 Trait (6 methods - SLIM)
+```rust
+#[async_trait]
+trait AgentV2: Send + Sync + Debug {
+    fn id(&self) -> AgentId;
+    fn name(&self) -> &str;
+    fn runtime(&self) -> &AgentRuntime;
+
+    /// Process a message, streaming response events
+    async fn process(
+        self: Arc<Self>,
+        message: Message,
+    ) -> Result<Box<dyn Stream<Item = ResponseEvent> + Send + Unpin>>;
+
+    async fn state(&self) -> AgentState;
+    async fn set_state(&self, state: AgentState) -> Result<()>;
+}
+```
+
+### Where Did Everything Go?
+
+| Old Method | New Location | Access Pattern |
+|------------|--------------|----------------|
+| `get_memory()` | `runtime().memory()` | Via `context` tool |
+| `update_memory()` | `runtime().memory()` | Via `context` tool |
+| `set_memory()` | `runtime().memory()` | Via `context` tool |
+| `list_memory_keys()` | `runtime().memory()` | Via `context` tool |
+| `share_memory_with()` | MemoryStore directly | Via tool or Runtime method |
+| `get_shared_memories()` | MemoryStore directly | Via tool or Runtime method |
+| `execute_tool()` | `runtime().execute_tool()` | Direct call in process loop |
+| `available_tools()` | `runtime().tools()` | Direct access |
+| `system_prompt()` | ContextBuilder | Built during prepare_request |
+| `register_endpoint()` | `runtime().router()` | Direct access |
+| `set_default_user_endpoint()` | `runtime().router()` | Direct access |
+| `handle()` | `runtime()` | Direct access |
+| `agent_type()` | Removed from trait | Metadata on impl if needed |
+| `last_active()` | Removed from trait | Query from DB if needed |

+
+**Files:**
+- Create: `crates/pattern_core/src/agent_v2/mod.rs`
+- Create: `crates/pattern_core/src/agent_v2/traits.rs`
+- Modify: `crates/pattern_core/src/lib.rs` (add module)
+
+**Step 1: Create agent_v2 module structure**
+
+Create `crates/pattern_core/src/agent_v2/mod.rs`:
+```rust
+//! V2 Agent framework with slim trait design
+//!
+//! The AgentV2 trait is dramatically slimmer than the original Agent trait:

+//! - Memory access is via tools, not direct trait methods
+
+mod traits;

+
+**Step 2: Define the slim AgentV2 trait**
+
+Create `crates/pattern_core/src/agent_v2/traits.rs`:

+}
+```
+
+**Step 3: Add module to lib.rs**
+
+In `crates/pattern_core/src/lib.rs`, add:
+```rust
+pub mod agent_v2;
+pub use agent_v2::{AgentV2, AgentV2Ext};
+```
+
+**Step 4: Verify compilation**

+
+## Success Criteria
+
+- [ ] `cargo check -p pattern_core` passes
+- [ ] `cargo test -p pattern_core agent_v2` passes
+- [ ] AgentV2 trait has exactly 6 methods (id, name, runtime, process, state, set_state)
+- [ ] DatabaseAgentV2 implements AgentV2 trait
+- [ ] Old Agent trait and DatabaseAgent still compile (parallel development)
+- [ ] AgentRuntime has execute_tool method
+- [ ] AgentV2Ext provides process_to_response convenience method
+
+---
+
+## Next Steps (Phase E)
+
+After Phase D is complete:
+1. Update heartbeat processor to work with AgentV2
+2. Port built-in tools to use Runtime instead of AgentHandle
+3. Integration tests with real model providers
+4. Eventually: swap Agent → AgentV2, remove old code

+# ToolExecutor Design
+
+## Overview
+
+The ToolExecutor is a component of AgentRuntime that handles tool execution with:
+- **Rule validation** (ToolRuleEngine) - prevent invalid sequences, enforce constraints
+- **Permission arbitration** (PermissionBroker) - consent flow for sensitive tools
+- **Deduplication** - avoid redundant executions within time window
+- **Timeout handling** - prevent hung tools
+- **Continuation tracking** - heartbeat/ContinueLoop logic
+
+## State Scoping
+
+Three categories of state with different lifecycles:
+
+### Per-Process State (resets each `process()` call, including heartbeats)
+Ordering and sequencing within a single processing invocation:
+- `execution_history: Vec<ToolExecution>` - for ordering constraints
+- `start_constraints_satisfied: bool`
+- `exit_requirements_pending: Vec<String>`
+- `phase: ExecutionPhase`
+
+### Per-Batch State (survives heartbeat continuations within same batch)
+Loop prevention that must span heartbeat continuations:
+- `call_counts: HashMap<String, u32>` - for MaxCalls rule
+- `exclusive_groups_used: HashMap<String, String>` - group_id -> tool_name
+
+This state is keyed by batch_id and cached on ToolExecutor:
+```rust
+batch_constraints: DashMap<SnowflakePosition, BatchConstraints>
+```
+
+### Persistent State (lives on ToolExecutor, spans all batches)
+These span across batches:
+- `dedupe_cache: DashMap<String, Instant>` - recent executions by canonical key
+- `last_execution: DashMap<String, Instant>` - for Cooldown rules
+- `standing_grants: DashMap<String, PermissionGrant>` - standing approvals only

+
+## Integration with DatabaseAgentV2::process()
+
+```rust

+    // persistent state remains on tool_executor
+}
+```
+
+## Rule Scoping Summary
+
+| Rule Type | Scope | Prevents |
+|-----------|-------|----------|
+| MaxCalls(n) | Per-batch | Infinite loops |
+| ExclusiveGroups | Per-batch | Conflicting operations |
+| StartConstraint | Per-batch | Wrong ordering |
+| RequiresPrecedingTools | Per-batch | Wrong ordering |
+| RequiresFollowingTools | Per-batch | Wrong ordering |
+| RequiredBeforeExit | Per-batch | Missing cleanup |
+| ContinueLoop | N/A (static) | Unnecessary heartbeats |
+| ExitLoop | Per-batch | Runaway processing |
+| Cooldown(duration) | Persistent | Rate limiting |
+| RequiresConsent | Persistent (grants) | Unauthorized actions |
+
+## Permission Model for RequiresConsent
+
+**RequiresConsent tools are rare, sensitive operations.** They ALWAYS require explicit permission unless a standing grant exists.
+
+**Grant types:**
+- `ApproveOnce` - Single use, not cached, next call requires new approval
+- `ApproveForDuration(Duration)` - Standing grant with expiry, cached
+- `ApproveForScope` - Standing grant for this scope, cached until revoked
+- `Deny` - Rejected, not cached
+
+**Flow:**
+```
+Tool has RequiresConsent rule?
+│
+├─► Check for standing grant (ApproveForDuration or ApproveForScope)
+│   ├─ Found and not expired → Execute with grant
+│   └─ Not found or expired → Request permission
+│
+└─► permission_broker.request(...)
+    ├─ ApproveOnce → Execute, do NOT cache
+    ├─ ApproveForDuration/Scope → Execute AND cache grant
+    ├─ Deny → Err(PermissionDenied)
+    └─ Timeout → Err(PermissionDenied)
+```
+
+**Key principle:** No implicit grant caching. Only explicit standing grants (`ApproveForDuration`, `ApproveForScope`) are cached. One-time approvals (`ApproveOnce`) are consumed immediately.
+
+---
+
+## Open Questions
+
+1. **Dedupe granularity**: Current uses canonical args. Should some tools be dedupe-exempt?
+   - Maybe a rule type: `NeverDedupe` or `AlwaysDedupe`
+
+2. **Periodic tools**: The ToolRuleType::Periodic exists but isn't covered here.
+   - Needs external timer to trigger, not part of execute() flow
+
+3. **Error recovery**: If execute_batch hits an error, should it continue with remaining tools?
+   - Current design: stops on execution error, continues on tool-returned error
+
+---
+
+## Next Steps
+
+1. Implement `ToolExecutor` struct and `new_batch()`
+2. Implement `execute()` with full flow
+3. Implement `execute_batch()`, `execute_start_constraints()`, `execute_exit_requirements()`
+4. Add to `AgentRuntime` via builder
+5. Update `RuntimeConfig` to include `ToolExecutorConfig`
+6. Tests for each rule type

+# V2 Integration Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Replace SurrealDB with SQLite/pattern_db, rewrite memory system with Loro CRDT and agent-scoping, refactor DatabaseAgent to use new infrastructure.
+
+**Architecture:** Three sequential chunks - database replacement provides foundation, memory rework builds on new storage, agent rework integrates both into unified runtime.
+
+**Tech Stack:** SQLite + sqlx, Loro CRDT, pattern_db crate, sqlite-vec, FTS5
+
+---
+
+## Overview
+
+This is a major refactoring effort split into four chunks:
+
+| Chunk | Description | Depends On |
+|-------|-------------|------------|
+| **1. Database Layer** | Add db_v2 module wrapping pattern_db | None |
+| **2. Memory System** | Agent-scoped, structured Loro documents | Chunk 1 |
+| **2.5. Context Rework** | Block type handling, summaries, activity logs | Chunk 2 |
+| **3. Agent Rework** | New DatabaseAgent using new systems | Chunks 1, 2, 2.5 |
+
+Each chunk has its own detailed plan document (linked below) for subagent dispatch.
+
+### Key Design Documents
+
+- `docs/refactoring/v2-structured-memory-sketch.md` - Structured Loro types, block schemas
+- `docs/refactoring/v2-memory-system.md` - Memory architecture details
+- `docs/refactoring/v2-database-design.md` - SQLite schema
+
+---
+
+## Chunk 1: Rip Out SurrealDB
+
+**Goal:** Remove all SurrealDB dependencies from pattern_core, replace with pattern_db.
+
+**Scope:**
+- Remove `surrealdb` dependency from pattern_core
+- Remove Entity macro usage (replace with direct sqlx)
+- Replace db/client.rs global DB with ConstellationDb pattern
+- Replace db/ops.rs operations with pattern_db queries
+- Update all code that imports from db module
+- Keep existing in-memory Memory system temporarily (chunk 2 replaces it)
+
+**Key Files to Change:**
+- `crates/pattern_core/Cargo.toml` - remove surrealdb, add pattern_db
+- `crates/pattern_core/src/db/` - entire module rewrite
+- `crates/pattern_core/src/agent/entity.rs` - remove Entity derive
+- `crates/pattern_core/src/memory.rs` - remove Entity derive (keep struct)
+- `crates/pattern_core/src/message.rs` - remove Entity derive
+
+**Deliverable:** pattern_core compiles and tests pass with SQLite backend, no SurrealDB.
+
+**Detailed Plan:** `docs/plans/2025-01-23-chunk1-surrealdb-removal.md`
+
+---
+
+## Chunk 2: Memory System
+
+**Goal:** Replace DashMap-based user-scoped memory with agent-scoped, structured Loro-backed system.
+
+**Scope:**
+- New `MemoryStore` trait abstracting memory operations
+- Agent-scoped ownership (agent_id instead of owner_id/user_id)
+- **Structured Loro documents** - Text, List, Map, Tree, Counter types
+- **Block schemas** - Define structure for templated blocks
+- Shared block system via `shared_block_agents` table
+- Typed operations (append_to_list, set_field, increment_counter)
+
+**Key Changes:**
+- `crates/pattern_core/src/memory_v2/` - new module (alongside old)
+- `memory_v2/types.rs` - BlockType, Permission, schemas
+- `memory_v2/document.rs` - Loro wrapper with typed operations
+- `memory_v2/store.rs` - MemoryStore trait + SQLite impl
+- `memory_v2/sharing.rs` - Shared block support
+
+**New Dependencies:**
+- `loro = "1.10"` with `features = ["counter"]`
+
+**Deliverable:** Memory system with structured types, agent-scoped, SQLite-backed.
+
+**Detailed Plan:** `docs/plans/2025-01-23-chunk2-memory-rework.md`
+
+**Design Reference:** `docs/refactoring/v2-structured-memory-sketch.md`
+
+---
+
+## Chunk 2.5: Context & Prompt Rework
+
+**Goal:** Update context building for new block types, structured summaries, activity logging.
+
+**Scope:**
+- Block type differentiation (Core/Working/Log/Archival)
+- **Structured summaries** - SummaryBlock with chaining, topics, time ranges
+- **Activity log integration** - Events to database, Log block as view
+- Context builder aware of block schemas
+- System prompt templates for structured blocks
+
+**Key Changes:**
+- `crates/pattern_core/src/context_v2/` - new module
+- `context_v2/builder.rs` - New context builder
+- `context_v2/summary.rs` - Structured SummaryBlock
+- `context_v2/activity.rs` - Activity event logging
+- `context_v2/prompt.rs` - System prompt templates
+
+**Key Features:**
+- Log blocks show recent N entries with timestamps
+- Structured blocks render to readable format for LLM
+- Summaries include metadata (time range, topics, message count)
+- Activity events persist to `activity_events` table
+
+**Deliverable:** Context building that handles structured memory and rich summaries.
+
+**Detailed Plan:** `docs/plans/2025-01-23-chunk2.5-context-rework.md` (TODO)
+
+---
+
+## Chunk 3: Agent Rework
+
+**Goal:** Refactor DatabaseAgent to use new database and memory systems.
+
+**Scope:**
+- Remove SurrealDB connection from DatabaseAgent
+- Inject ConstellationDb instead
+- Use MemoryStore trait for memory operations
+- Update context building to use new memory format
+- Preserve message batching with SQLite backend
+- Update AgentRecord persistence
+
+**Key Changes:**
+- `crates/pattern_core/src/agent/impls/db_agent.rs` - major refactor
+- `crates/pattern_core/src/agent/entity.rs` - simplify, no Entity macro
+- `crates/pattern_core/src/context/state.rs` - use new memory
+- `crates/pattern_core/src/context/compression.rs` - adapt for SQLite
+
+**Deliverable:** Agents run with full SQLite backend, memory persists correctly.
+
+**Detailed Plan:** `docs/plans/2025-01-23-chunk3-agent-rework.md`
+
+---
+
+## Pattern_DB Gaps to Fill First
+
+Before starting chunks, pattern_db needs these additions:
+
+### Critical (Blocking)
+1. **`update_agent()` full update** - Currently only status update exists
+2. **`update_block()` full update** - Currently only content update exists
+3. **Loro helper functions** - Deserialize/serialize helpers for application layer
+
+### Important (Can parallelize)
+4. **Message embedding storage** - Add embeddings column or table
+5. **Batch integrity queries** - Check tool call pairing
+
+---
+
+## Execution Strategy
+
+### Option A: Sequential (Safer)
+1. Fill pattern_db gaps
+2. Chunk 1 (SurrealDB removal)
+3. Chunk 2 (Memory rework)
+4. Chunk 3 (Agent rework)
+5. Integration testing
+
+### Option B: Parallel Foundation + Sequential Core
+1. **Parallel:** Fill pattern_db gaps + write Chunk 1 plan details
+2. **Sequential:** Execute Chunks 1 → 2 → 3
+3. Integration testing
+
+### Option C: Maximum Parallelism (Riskier)
+1. Fill pattern_db gaps
+2. **Parallel:** Chunk 1 (new db layer) + Chunk 2 design (memory interfaces)
+3. **Sequential:** Chunk 2 implementation → Chunk 3
+4. Integration testing
+
+---
+
+## Success Criteria
+
+- [ ] `cargo check -p pattern_core` passes with no surrealdb imports
+- [ ] `cargo test -p pattern_core` passes
+- [ ] Memory blocks persist with agent_id ownership
+- [ ] Loro versioning works (can view history, rollback)
+- [ ] Search uses FTS5 + sqlite-vec
+- [ ] Existing CLI commands work (agent create, chat, memory operations)
+- [ ] Discord/Bluesky integrations unaffected
+
+---
+
+## Risk Mitigation
+
+1. **Data Migration:** CAR export from v1, import to v2 - separate migration tool
+2. **Feature Parity:** Keep existing tool interfaces, change backends only
+3. **Testing:** Each chunk has integration tests before proceeding
+4. **Rollback:** Git branches per chunk, can revert if needed
+
+---
+
+## Incremental Development Strategy
+
+**Key insight:** We don't need everything working immediately. Old code can stay for compiler feedback.
+
+**Approach:**
+- Create new modules alongside old (e.g., `memory_v2.rs`, `agent_v2.rs`)
+- Old SurrealDB code stays compilable - gives us type checking
+- New code imports from pattern_db, implements new patterns
+- Gradual swap-over: update callsites one at a time
+- Delete old modules only when fully migrated and tested
+
+**Benefits:**
+- Compiler errors guide what's missing in new system
+- Can run old and new side-by-side for comparison
+- No "big bang" switch - reduces risk
+- Easier to pause/resume work
+
+**Example Structure During Migration:**
+```
+pattern_core/src/
+├── memory.rs          # OLD: DashMap, user-scoped (keep for now)
+├── memory_v2.rs       # NEW: Loro, agent-scoped
+├── agent/
+│   └── impls/
+│       ├── db_agent.rs      # OLD: SurrealDB
+│       └── db_agent_v2.rs   # NEW: SQLite/pattern_db
+├── db/
+│   ├── mod.rs         # OLD: SurrealDB ops (keep)
+│   └── sqlite.rs      # NEW: pattern_db integration
+```
+
+---
+
+## Next Steps
+
+1. User confirms chunk strategy and execution option
+2. Write detailed plan for Chunk 1
+3. Begin execution (or dispatch to subagents)

+# E2.5 Completion: Trait Swap Finalization
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Complete the trait swap by removing AgentHandle, V1 tool implementations, and Entity macro derives so that `cargo check` shows only expected trait incompatibility errors (E3-E6 work).
+
+**Architecture:** Replace all AgentHandle usages with ToolContext (the new minimal API for tools). Remove Entity macro derives from types in pattern_core and transition to pattern_db models. Old code stays as `.bak` reference files.
+
+**Tech Stack:** Rust, async-trait, pattern_db (SQLite), ToolContext trait
+
+**Reference:** See `docs/plans/2025-01-24-phase-e-integration.md` for full context.
+
+---
+
+## Scope Boundaries
+
+### In Scope (This Plan)
+- Remove AgentHandle type and all usages
+- Remove V1 tool implementations (RecallTool, ContextTool, SearchTool, SendMessageTool)
+- Update BuiltinTools to use only V2 versions
+- Update tool tests to use mock ToolContext
+- Remove Entity macro derives from core modules
+- Fix doc comments (AgentV2 → Agent)
+
+### Out of Scope (Later Work)
+- `data_source/` module fixes (staged separately)
+- `coordination/groups.rs` Entity derives (requires db schema work)
+- Identity module (`atproto_identity.rs`, `discord_identity.rs`) - separate planning
+- Auth module (`oauth.rs`) - separate planning
+- Export/import module - moves to compat crate later
+
+### Expected Final State
+After E2.5, `cargo check -p pattern_core` should show:
+- **Expected errors:** Trait method mismatches in heartbeat.rs, coordination patterns (E3-E4 work)
+- **No unexpected errors:** No missing imports, no AgentHandle references, no Entity macro failures in core modules
+
+---
+
+## Task 1: Create Mock ToolContext for Tests
+
+**Files:**
+- Create: `crates/pattern_core/src/tool/builtin/test_utils.rs`
+- Modify: `crates/pattern_core/src/tool/builtin/mod.rs`
+
+**Step 1: Create test_utils.rs with MockToolContext**
+
+```rust
+//! Test utilities for built-in tools
+
+use async_trait::async_trait;
+use std::sync::Arc;
+
+use crate::memory::{MemoryResult, MemorySearchResult, MemoryStore, SearchOptions};

+/// Mock ToolContext for testing V2 tools
+pub struct MockToolContext {
+    agent_id: String,
+    memory: Arc<dyn MemoryStore>,
+    router: AgentMessageRouter,
+}
+
+impl MockToolContext {
+    pub fn new(agent_id: impl Into<String>, memory: Arc<dyn MemoryStore>) -> Self {
+        Self {
+            agent_id: agent_id.into(),
+            memory,
+            router: AgentMessageRouter::new_cli(), // Default to CLI router for tests
+        }
+    }
+}
+
+#[async_trait]

+        self.memory.as_ref()
+    }

+    fn router(&self) -> &AgentMessageRouter {
+        &self.router
+    }
+
+    fn model(&self) -> Option<&dyn ModelProvider> {
+        None
+    }
+
+    fn permission_broker(&self) -> &'static PermissionBroker {

+
+    async fn search(
+        &self,
+        query: &str,
+        scope: SearchScope,
+        options: SearchOptions,
+    ) -> MemoryResult<Vec<MemorySearchResult>> {
+        match scope {
+            SearchScope::CurrentAgent => {
+                self.memory.search(&self.agent_id, query, options).await
+            }
+            SearchScope::Agent(ref id) => {
+                self.memory.search(id.as_str(), query, options).await
+            }
+            SearchScope::Agents(ref ids) => {
+                let mut all = Vec::new();
+                for id in ids {
+                    if let Ok(results) = self.memory.search(id.as_str(), query, options.clone()).await {
+                        all.extend(results);
+                    }
+                }
+                Ok(all)

+            }
+        }
+    }
+}
+```
+
+**Step 2: Export from mod.rs**
+
+In `crates/pattern_core/src/tool/builtin/mod.rs`, add:
+
+```rust
+#[cfg(test)]
+mod test_utils;
+
+#[cfg(test)]
+pub use test_utils::MockToolContext;
+```
+
+**Step 3: Run cargo check**
+
+```bash
+cargo check -p pattern_core --lib
+```
+
+Expected: May fail due to other issues; this step just adds test infrastructure.
+
+**Step 4: Commit**
+
+```bash
+git add crates/pattern_core/src/tool/builtin/test_utils.rs
+git add crates/pattern_core/src/tool/builtin/mod.rs
+git commit -m "test(tools): add MockToolContext for V2 tool testing"
+```
+
+---
+
+## Task 2: Remove V1 RecallTool Implementation
+
+**Files:**
+- Modify: `crates/pattern_core/src/tool/builtin/recall.rs`
+
+**Step 1: Remove AgentHandle import**
+
+Remove this line:
+```rust
+use crate::context::AgentHandle;
+```
+
+**Step 2: Remove RecallTool struct and all its impl blocks**
+
+Delete lines 76-459 (the entire `RecallTool` struct, its `AiTool` impl, and helper methods).
+
+Keep only:
+- Input/Output types (RecallInput, RecallOutput, ArchivalSearchResult, ArchivalMemoryOperationType)
+- RecallToolV2 implementation (lines 461-977)
+- Update tests to use V2
+
+**Step 3: Rename RecallToolV2 to RecallTool**
+
+Find and replace in the file:
+- `RecallToolV2` → `RecallTool`
+
+**Step 4: Update tests to use MockToolContext**
+
+Replace test code that uses `AgentHandle::test_with_memory` with MockToolContext:
+
+```rust
+#[cfg(test)]

+
+## Task 6: Update BuiltinTools to Use V2 Only
+
+**Files:**
+- Modify: `crates/pattern_core/src/tool/builtin/mod.rs`
+
+**Step 1: Remove AgentHandle import**
+
+Remove:
+```rust
+use crate::context::AgentHandle;
+```
+
+**Step 2: Remove V1 BuiltinTools struct**
+
+Delete `BuiltinTools` struct (lines 48-56), its `impl` block (lines 58-106), and `BuiltinToolsBuilder` (lines 108-161).
+
+**Step 3: Rename BuiltinToolsV2 to BuiltinTools**
+
+Find and replace:
+- `BuiltinToolsV2` → `BuiltinTools`
+
+**Step 4: Update exports**
+
+Remove V2 suffix from public exports:
+```rust
+pub use context::{ContextInput, ContextOutput, ContextTool, CoreMemoryOperationType};
+pub use recall::{
+    ArchivalMemoryOperationType, ArchivalSearchResult, RecallInput, RecallOutput, RecallTool,
+};

+
+---
+
+## Task 7: Remove AgentHandle from Context Module
+
+**Files:**
+- Modify: `crates/pattern_core/src/context/mod.rs`
+
+**Step 1: Check current exports**
+
+Read the file and identify any AgentHandle exports or references.
+
+**Step 2: Remove AgentHandle export if present**
+
+If `pub use ... AgentHandle` exists, remove it. The type now lives only in the backup file.
+
+**Step 3: Ensure no other context code references AgentHandle**
+
+Search for AgentHandle in context/*.rs files (excluding .bak).
+
+**Step 4: Commit**
+
+```bash
+git add crates/pattern_core/src/context/mod.rs
+git commit -m "refactor(context): remove AgentHandle export"
+```
+
+---
+
+## Task 8: Fix Doc Comments (AgentV2 → Agent)
+
+**Files:**
+- Modify: `crates/pattern_core/src/agent/mod.rs`
+- Modify: `crates/pattern_core/src/agent/traits.rs`
+
+**Step 1: Update agent/mod.rs**
+
+Line 3: Change `//! The AgentV2 trait is dramatically slimmer...` to `//! The Agent trait is dramatically slimmer...`
+
+**Step 2: Update agent/traits.rs**
+
+Line 1: Change `//! Core AgentV2 trait...` to `//! Core Agent trait...`
+Line 57: Change `/// Extension trait for AgentV2...` to `/// Extension trait for Agent...`
+Line 59: Change `...implement AgentV2.` to `...implement Agent.`
+Line 76: Change `// Blanket implementation for all AgentV2 types` to `// Blanket implementation for all Agent types`
+
+**Step 3: Commit**
+
+```bash
+git add crates/pattern_core/src/agent/mod.rs
+git add crates/pattern_core/src/agent/traits.rs
+git commit -m "docs(agent): update comments to reflect Agent trait rename"
+```
+

+
+## Task 9: Backup and Remove Entity Derives from message.rs
+
+**Files:**
+- Backup: `crates/pattern_core/src/message.rs` → `crates/pattern_core/src/message.rs.entity.bak`
+- Modify: `crates/pattern_core/src/message.rs`
+
+**Step 1: Create backup of Entity-derived types section**
+
+Copy the Entity-derived structs (Message, AgentMessageRelation) to a .bak file for reference.
+
+**Step 2: Remove Entity derive from Message**
+
+Change:
+```rust
+#[derive(Debug, Clone, Entity, Serialize, Deserialize)]
+#[entity(entity_type = "message")]
+pub struct Message {
+```
+
+To:
+```rust
+#[derive(Debug, Clone, Serialize, Deserialize)]
+pub struct Message {
+```
+
+**Step 3: Remove Entity derive from AgentMessageRelation**
+
+Same pattern - remove `Entity` from derive and remove `#[entity(...)]` attribute.
+
+**Step 4: Remove pattern_macros::Entity import if no longer needed**
+
+**Step 5: Run cargo check**
+
+```bash
+cargo check -p pattern_core --lib
+```
+
+Expected: Errors where code tries to use Entity trait methods on Message. These indicate code that needs updating to use pattern_db.
+
+**Step 6: Commit**
+
+```bash
+git add crates/pattern_core/src/message.rs
+git commit -m "refactor(message): remove Entity macro derive, use pattern_db models"
+```
+
+---
+
+## Task 10: Backup and Remove Entity Derives from message_queue.rs
+
+**Files:**
+- Modify: `crates/pattern_core/src/message_queue.rs`
+
+**Step 1: Remove Entity derives from QueuedMessage and ScheduledWakeup**
+
+Same pattern as Task 9.
+
+**Step 2: Commit**
+
+```bash
+git add crates/pattern_core/src/message_queue.rs
+git commit -m "refactor(message_queue): remove Entity macro derive"
+```
+
+---
+
+## Task 11: Backup and Remove Entity Derives from users.rs
+
+**Files:**
+- Modify: `crates/pattern_core/src/users.rs`
+
+Remove Entity derive from User struct.
+
+**Commit message:** `refactor(users): remove Entity macro derive`
+
+---
+
+## Task 12: Handle agent/entity.rs Entity Derives
+
+**Files:**
+- Modify: `crates/pattern_core/src/agent/entity.rs`
+
+**Important:** AgentRecord and AgentMemoryRelation are core types. Removing Entity derive will break db_v1 operations.
+
+**Step 1: Remove Entity derives**
+
+Remove `Entity` from derive and `#[entity(...)]` attributes from:
+- `AgentRecord`
+- `AgentMemoryRelation`
+
+**Step 2: Note resulting errors**
+
+These errors indicate db_v1 code that needs to move to compat crate. This is expected.
+
+**Step 3: Commit**
+
+```bash
+git add crates/pattern_core/src/agent/entity.rs
+git commit -m "refactor(agent): remove Entity macro derives from AgentRecord
+
+BREAKING: db_v1 operations on AgentRecord will fail.
+This is intentional - db_v1 code moves to compat crate."
+```
+
+---
+
+## Task 13: Verify Error State
+
+**Step 1: Run full cargo check**
+
+```bash
+cargo check -p pattern_core 2>&1 | tee /tmp/e25-final-errors.txt
+```
+
+**Step 2: Categorize errors**
+
+Expected errors (E3-E6 work):
+- Heartbeat: `trait Agent has no method X`
+- Coordination patterns: `process_message_stream` not found
+- db_v1 operations: `DbEntity` not implemented
+
+Unexpected errors (fix before proceeding):
+- Missing imports unrelated to the changes
+- Type errors in unrelated code
+
+**Step 3: Document remaining work**
+
+Create a summary of which errors are expected vs unexpected.
+
+---
+
+## Task 14: Clean Up Empty Directories
+
+**Step 1: Remove empty agent_v2 directory**
+
+```bash
+rmdir crates/pattern_core/src/agent_v2
+```
+
+**Step 2: Remove empty context_v2 directory**
+
+```bash
+rmdir crates/pattern_core/src/context_v2
+```
+
+**Step 3: Commit**
+
+```bash
+git add -A
+git commit -m "chore: remove empty v2 directories after trait swap"
+```
+
+---
+
+## Verification Checklist
+
+After completing all tasks:
+
+- [ ] No `AgentHandle` references in non-.bak files (except data_source/ which is out of scope)
+- [ ] No `V2` suffix on tool types (RecallTool, not RecallToolV2)
+- [ ] No `AgentV2` in doc comments
+- [ ] Entity macro only used in out-of-scope files (coordination/groups.rs, identity modules, oauth.rs)
+- [ ] `cargo check -p pattern_core` shows only expected trait incompatibility errors
+- [ ] All .bak files preserved for reference
+
+---
+
+## Post-E2.5 Work
+
+These errors remain and are addressed in later phases:
+
+1. **E3: Heartbeat Processor** - Update for new Agent trait
+2. **E4: Coordination Patterns** - Update for new Agent trait
+3. **E5: Message Queue** - Port to pattern_db
+4. **E6: CLI/Discord** - Create RuntimeContext
+5. **Compat Crate** - Move db_v1, old export/import
+6. **Identity/Auth** - Separate planning with database schema work

+# Phase E: V2 Integration - Detailed Implementation Tasks
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Integrate DatabaseAgentV2 and AgentRuntime with the rest of the codebase, swapping V2 traits to become the primary Agent trait.
+
+**Architecture:** Pre-E1 fixes ContextBuilder gaps, E1-E2 create ToolContext and update tools, E2.5 swaps traits (expect breaks), E3-E5 fix consumers guided by compiler, E6 creates RuntimeContext and simplifies CLI/Discord.
+
+**Tech Stack:** Rust, async-trait, tokio, pattern_db (SQLite), Loro CRDT
+
+**Reference:** See `docs/plans/2025-01-24-phase-e-integration.md` for architecture decisions and context.

+
+## Pre-E1: Fix ContextBuilder Missing Fields
+
+### Task Pre-E1.1: Add base_instructions to ContextBuilder
+
+**Files:**
+- Modify: `crates/pattern_core/src/context_v2/builder.rs`
+
+**Step 1: Add base_instructions field to ContextBuilder struct**
+
+In `builder.rs`, find the `ContextBuilder` struct (around line 23-32) and add:
+
+```rust
+pub struct ContextBuilder<'a> {
+    memory: &'a dyn MemoryStore,
+    messages: Option<&'a MessageStore>,
+    tools: Option<&'a ToolRegistry>,
+    config: &'a ContextConfig,
+    agent_id: Option<String>,
+    model_info: Option<&'a ModelInfo>,
+    active_batch_id: Option<SnowflakePosition>,
+    model_provider: Option<Arc<dyn ModelProvider>>,
+    base_instructions: Option<String>,  // ADD THIS
+}
+```
+
+**Step 2: Update the new() constructor**
+
+Find `fn new()` and add initialization:
+
+```rust
+pub fn new(memory: &'a dyn MemoryStore, config: &'a ContextConfig) -> Self {
+    Self {
+        memory,
+        messages: None,
+        tools: None,
+        config,
+        agent_id: None,
+        model_info: None,
+        active_batch_id: None,
+        model_provider: None,
+        base_instructions: None,  // ADD THIS
+    }
+}
+```
+
+**Step 3: Add builder method**
+
+After `with_model_provider()` method, add:
+
+```rust
+/// Set the base instructions (system prompt) for this context
+///
+/// These instructions are prepended to the system prompt before memory blocks.
+pub fn with_base_instructions(mut self, instructions: impl Into<String>) -> Self {
+    self.base_instructions = Some(instructions.into());
+    self
+}
+```
+
+**Step 4: Update build_system_prompt to include base_instructions**
+
+Find `async fn build_system_prompt()` (around line 158-189) and modify:
+
+```rust
+async fn build_system_prompt(&self, agent_id: &str) -> Result<Vec<String>, CoreError> {
+    let mut prompt_parts = Vec::new();
+
+    // Base instructions come first (if set)
+    if let Some(ref instructions) = self.base_instructions {
+        if !instructions.is_empty() {
+            prompt_parts.push(instructions.clone());
+        }
+    }
+
+    // Get and render Core blocks
+    let core_blocks = self
+        .memory
+        .list_blocks_by_type(agent_id, BlockType::Core)
+        // ... rest unchanged
+```
+
+**Step 5: Run cargo check**
+
+```bash
+cargo check -p pattern_core
+```
+
+Expected: Compiles without errors.
+
+**Step 6: Commit**
+
+```bash
+git add crates/pattern_core/src/context_v2/builder.rs
+git commit -m "feat(context_v2): add base_instructions to ContextBuilder"
+```
+
+---
+
+### Task Pre-E1.2: Add tool_rules to ContextBuilder
+
+**Files:**
+- Modify: `crates/pattern_core/src/context_v2/builder.rs`
+
+**Step 1: Add import for ToolRule**
+
+At the top of builder.rs, add:
+
+```rust
+use crate::agent::tool_rules::ToolRule;
+```
+
+**Step 2: Add tool_rules field to ContextBuilder struct**
+
+```rust
+pub struct ContextBuilder<'a> {
+    // ... existing fields ...
+    base_instructions: Option<String>,
+    tool_rules: Vec<ToolRule>,  // ADD THIS
+}
+```
+
+**Step 3: Update new() constructor**
+
+```rust
+tool_rules: Vec::new(),  // ADD THIS in new()
+```
+
+**Step 4: Add builder method**
+
+```rust
+/// Set the tool rules that should be included in the system prompt
+///
+/// Tool rules are appended to the system prompt so the model knows the constraints.
+pub fn with_tool_rules(mut self, rules: Vec<ToolRule>) -> Self {
+    self.tool_rules = rules;
+    self
+}
+```
+
+**Step 5: Update build_system_prompt to include tool rules**
+
+At the end of `build_system_prompt()`, before the `Ok(prompt_parts)`:
+
+```rust
+    // ... after Working blocks ...
+
+    // Append tool rules summary if any
+    if !self.tool_rules.is_empty() {
+        let rules_text = self.render_tool_rules();
+        if !rules_text.is_empty() {
+            prompt_parts.push(rules_text);
+        }
+    }
+
+    Ok(prompt_parts)
+}
+```
+
+**Step 6: Add render_tool_rules helper method**
+
+Add this method to the impl block:
+
+```rust
+/// Render tool rules as a human-readable section for the system prompt
+fn render_tool_rules(&self) -> String {
+    if self.tool_rules.is_empty() {
+        return String::new();
+    }
+
+    let mut lines = vec!["# Tool Usage Rules".to_string()];
+    lines.push(String::new());
+
+    for rule in &self.tool_rules {
+        lines.push(format!("- {}", rule.description()));
+    }
+
+    lines.join("\n")
+}
+```
+
+**Step 7: Run cargo check**
+
+```bash
+cargo check -p pattern_core
+```
+
+Expected: Compiles. If `ToolRule::description()` doesn't exist, check `tool_rules.rs` for the actual method name (might be `to_string()` or similar).
+
+**Step 8: Commit**
+
+```bash
+git add crates/pattern_core/src/context_v2/builder.rs
+git commit -m "feat(context_v2): add tool_rules to ContextBuilder system prompt"
+```
+
+---
+
+### Task Pre-E1.3: Add test for ContextBuilder with base_instructions and tool_rules
+
+**Files:**
+- Modify: `crates/pattern_core/src/context_v2/builder.rs` (tests module)
+
+**Step 1: Add test**
+
+In the `#[cfg(test)] mod tests` section at the bottom of builder.rs, add:
+
+```rust
+#[tokio::test]
+async fn test_builder_with_base_instructions() {
+    let memory = MockMemoryStore;
+    let config = ContextConfig::default();
+
+    let builder = ContextBuilder::new(&memory, &config)
+        .for_agent("test-agent")
+        .with_base_instructions("You are a helpful assistant.");
+
+    let request = builder.build().await.unwrap();
+
+    let system = request.system.unwrap();
+    // Base instructions should be first
+    assert!(system[0].contains("helpful assistant"));
+}
+
+#[tokio::test]
+async fn test_builder_with_tool_rules() {
+    use crate::agent::tool_rules::{ToolRule, ToolRuleType};
+
+    let memory = MockMemoryStore;
+    let config = ContextConfig::default();
+
+    // Create a simple tool rule for testing
+    let rule = ToolRule::new(
+        ToolRuleType::StartConstraint,
+        "send_message".to_string(),
+        "Must start with send_message".to_string(),
+    );
+
+    let builder = ContextBuilder::new(&memory, &config)
+        .for_agent("test-agent")
+        .with_tool_rules(vec![rule]);
+
+    let request = builder.build().await.unwrap();
+
+    let system = request.system.unwrap();
+    // Tool rules should be in the system prompt
+    let full_prompt = system.join("\n");
+    assert!(full_prompt.contains("Tool Usage Rules"));
+}
+```
+
+**Step 2: Run the test**
+
+```bash
+cargo test -p pattern_core test_builder_with_base_instructions -- --nocapture
+cargo test -p pattern_core test_builder_with_tool_rules -- --nocapture
+```
+
+Expected: Both tests pass.
+
+**Step 3: Commit**
+
+```bash
+git add crates/pattern_core/src/context_v2/builder.rs
+git commit -m "test(context_v2): add tests for base_instructions and tool_rules"
+```

+## E1: Define ToolContext Trait
+
+### Task E1.1: Create tool_context.rs with ToolContext trait and SearchScope
+
+**Files:**
+- Create: `crates/pattern_core/src/runtime/tool_context.rs`
+- Modify: `crates/pattern_core/src/runtime/mod.rs`
+
+**Step 1: Create the new file**
+
+Create `crates/pattern_core/src/runtime/tool_context.rs`:
+
+```rust
+//! ToolContext: What tools can access from the runtime

+}
+```
+
+**Step 2: Add module export to runtime/mod.rs**
+
+At the top of `runtime/mod.rs`, add the module declaration after the existing ones:
+
+```rust
+mod executor;
+mod router;
+mod tool_context;  // ADD THIS
+mod types;
+```
+
+And add the pub use:
+
+```rust
+pub use executor::{

+};
+pub use router::{AgentMessageRouter, MessageEndpoint, MessageOrigin};

+pub use types::RuntimeConfig;
+```
+
+**Step 3: Run cargo check**
+
+```bash
+cargo check -p pattern_core

+
+Expected: Compiles. May have warnings about unused code (that's fine for now).
+
+**Step 4: Commit**

+### Task E1.2: Implement ToolContext for AgentRuntime
+
+**Files:**
+- Modify: `crates/pattern_core/src/runtime/mod.rs`
+
+**Step 1: Add the impl block**
+
+At the end of `runtime/mod.rs`, before any test modules, add:
+
+```rust
+#[async_trait::async_trait]
+impl ToolContext for AgentRuntime {
+    fn agent_id(&self) -> &str {
+        &self.agent_id
+    }
+
+    fn memory(&self) -> &dyn MemoryStore {
+        self.memory.as_ref()
+    }
+
+    fn router(&self) -> &AgentMessageRouter {
+        &self.router
+    }
+
+    fn model(&self) -> Option<&dyn ModelProvider> {
+        self.model.as_ref().map(|m| m.as_ref())
+    }
+
+    async fn search(
+        &self,
+        query: &str,
+        scope: SearchScope,
+        options: SearchOptions,
+    ) -> MemoryResult<Vec<MemorySearchResult>> {
+        use crate::memory_v2::MemoryResult;
+
+        match scope {
+            SearchScope::CurrentAgent => {
+                self.memory.search(&self.agent_id, query, options).await
+            }
+            SearchScope::Agent(ref id) => {
+                // TODO: Add permission check here
+                // For now, allow all (will be restricted by role config later)
+                self.memory.search(id.as_str(), query, options).await
+            }
+            SearchScope::Agents(ref ids) => {
+                // Search each agent and merge results
+                let mut all_results = Vec::new();
+                for id in ids {
+                    // TODO: Add permission check per agent
+                    let results = self.memory.search(id.as_str(), query, options.clone()).await?;
+                    all_results.extend(results);
+                }
+                Ok(all_results)
+            }
+            SearchScope::Constellation => {
+                // TODO: Add permission check for broad access
+                // Search with None for agent_id to get all
+                self.memory.search_all(query, options).await
+            }
+        }
+    }
+}
+```
+
+**Step 2: Check if MemoryStore has search_all method**
+
+If `search_all` doesn't exist on MemoryStore, you may need to add it or use a different approach. Check `memory_v2/store.rs`. If missing, use:
+
+```rust
+SearchScope::Constellation => {
+    // Constellation-wide search - pass empty string or use dedicated method
+    // This is a placeholder - actual implementation depends on MemoryStore
+    self.memory.search("", query, options).await
+}
+```
+
+**Step 3: Add import at top of mod.rs**
+
+```rust
+use crate::memory_v2::{MemoryResult, MemorySearchResult, SearchOptions};
+use tool_context::{SearchScope, ToolContext};
+```
+
+**Step 4: Run cargo check**
+
+```bash
+cargo check -p pattern_core
+```
+
+Fix any missing imports or method signature mismatches.
+
+**Step 5: Commit**
+
+```bash
+git add crates/pattern_core/src/runtime/mod.rs
+git commit -m "feat(runtime): implement ToolContext for AgentRuntime"
+```
+
+---
+
+### Task E1.3: Add method to get Arc<dyn ToolContext> from AgentRuntime
+
+**Files:**
+- Modify: `crates/pattern_core/src/runtime/mod.rs`
+
+**Step 1: Add as_tool_context method to AgentRuntime impl**
+
+In the `impl AgentRuntime` block, add:
+
+```rust
+/// Get this runtime as a ToolContext trait object
+///
+/// This is used to pass the runtime to tools without exposing
+/// the full AgentRuntime API.
+pub fn as_tool_context(self: &Arc<Self>) -> Arc<dyn ToolContext> {
+    // Since AgentRuntime implements ToolContext, we can clone the Arc
+    // and cast it to the trait object
+    Arc::clone(self) as Arc<dyn ToolContext>
+}
+```
+
+Note: This requires AgentRuntime to be held in an Arc. Check if this is already the case in DatabaseAgentV2.
+
+**Step 2: Alternative if AgentRuntime is not in Arc**
+
+If AgentRuntime is owned directly (not in Arc), we need a different approach. Check `db_agent.rs` to see how runtime is stored. If it's not Arc, add this instead:
+
+```rust
+// In AgentRuntime impl
+/// Create a ToolContext wrapper that borrows this runtime
+///
+/// Note: The returned wrapper has the same lifetime as &self
+pub fn tool_context(&self) -> &dyn ToolContext {
+    self
+}
+```
+
+**Step 3: Run cargo check**
+
+```bash
+cargo check -p pattern_core
+```
+
+**Step 4: Commit**
+
+```bash
+git add crates/pattern_core/src/runtime/mod.rs
+git commit -m "feat(runtime): add as_tool_context method for tool access"
+```
+

+
+## E2: Update Built-in Tools
+
+### Task E2.1: Create ToolContext-based tool factory
+
+**Files:**
+- Modify: `crates/pattern_core/src/tool/builtin/mod.rs`
+
+**Step 1: Add import for ToolContext**
+
+At the top of `builtin/mod.rs`:
+
+```rust
+use crate::runtime::ToolContext;
+use std::sync::Arc;
+```
+
+**Step 2: Add new struct for V2 tools**
+
+After `BuiltinTools` struct, add:
+
+```rust
+/// Built-in tools that use ToolContext (V2 API)
+#[derive(Clone)]
+pub struct BuiltinToolsV2 {
+    context: Arc<dyn ToolContext>,
+}
+
+impl BuiltinToolsV2 {
+    /// Create built-in tools with a ToolContext
+    pub fn new(context: Arc<dyn ToolContext>) -> Self {
+        Self { context }
+    }
+
+    /// Register all V2 tools to a registry
+    pub fn register_all(&self, registry: &ToolRegistry) {
+        // TODO: Register V2 versions of tools
+        // This will be filled in as we update each tool
+
+        // For now, just a placeholder
+        tracing::debug!("BuiltinToolsV2::register_all called (tools not yet implemented)");
+    }
+}
+```
+
+**Step 3: Run cargo check**
+
+```bash
+cargo check -p pattern_core
+```
+
+**Step 4: Commit**
+
+```bash
+git add crates/pattern_core/src/tool/builtin/mod.rs
+git commit -m "feat(tools): add BuiltinToolsV2 struct for ToolContext-based tools"
+```
+
+---
+
+### Task E2.2: Update ContextTool to use ToolContext
+
+**Files:**
+- Modify: `crates/pattern_core/src/tool/builtin/context.rs`
+
+**Step 1: Add ToolContext import and create V2 struct**
+
+At the top of `context.rs`, add:
+
+```rust
+use crate::runtime::ToolContext;
+use std::sync::Arc;
+```
+
+After `ContextTool` struct, add:
+
+```rust
+/// V2 Context tool using ToolContext instead of AgentHandle
+pub struct ContextToolV2 {
+    ctx: Arc<dyn ToolContext>,
+}
+
+impl ContextToolV2 {
+    pub fn new(ctx: Arc<dyn ToolContext>) -> Self {
+        Self { ctx }
+    }
+}
+```
+
+**Step 2: Implement AiTool for ContextToolV2**
+
+Copy the `AiTool` impl from `ContextTool` and adapt it:
+
+```rust
+#[async_trait]
+impl AiTool for ContextToolV2 {
+    type Input = ContextInput;
+    type Output = ContextOutput;
+
+    fn name(&self) -> &str {
+        "context"
+    }
+
+    fn description(&self) -> &str {
+        // Same as ContextTool
+        "Manage the context/working memory..."
+    }
+
+    async fn execute(&self, params: Self::Input) -> Result<Self::Output> {
+        let agent_id = self.ctx.agent_id();
+        let memory = self.ctx.memory();
+
+        match params.operation {
+            CoreMemoryOperationType::Append => {
+                let name = params.name.ok_or_else(|| /* error */)?;
+                let content = params.content.ok_or_else(|| /* error */)?;
+
+                // Use memory store directly
+                if let Some(mut block) = memory.get_block(agent_id, &name).await
+                    .map_err(|e| CoreError::MemoryError(e.to_string()))?
+                {
+                    // Append to block
+                    // ... adapt from ContextTool
+                }
+                // ...
+            }
+            // ... other operations
+        }
+    }
+}
+```
+
+**Note:** This is complex - the full implementation requires adapting all operations. The key changes are:
+- Replace `self.handle.memory` with `self.ctx.memory()`
+- Replace `self.handle.agent_id()` with `self.ctx.agent_id()`
+- Use MemoryStore methods directly instead of AgentHandle convenience methods
+
+**Step 3: Run cargo check**
+
+```bash
+cargo check -p pattern_core
+```
+
+Fix errors as they appear. This will likely require multiple iterations.
+
+**Step 4: Commit**
+
+```bash
+git add crates/pattern_core/src/tool/builtin/context.rs
+git commit -m "feat(tools): add ContextToolV2 using ToolContext"
+```

+
+## E2.5: Trait Swap
+
+### Task E2.5.1: Backup old agent files
+
+**Step 1: Move old files out of source tree**
+
+```bash
+cd crates/pattern_core/src
+
+# Backup old DatabaseAgent
+mv agent/impls/db_agent.rs agent/impls/db_agent_v1.rs.bak
+
+# Backup AgentHandle (context state)
+mv context/state.rs context/state_v1.rs.bak
+```
+
+**Step 2: Verify files are moved**
+
+```bash
+ls agent/impls/*.bak
+ls context/*.bak
+```
+
+Expected: See the .bak files listed.
+
+**Step 3: Commit the backup**
+
+```bash
+git add -A
+git commit -m "chore: backup V1 agent files before trait swap"
+```
+
+---
+
+### Task E2.5.2: Move V2 files to primary locations
+
+**Step 1: Move agent_v2 files into agent**
+
+```bash
+cd crates/pattern_core/src
+
+# Move V2 database agent
+mv agent_v2/db_agent.rs agent/impls/db_agent.rs
+
+# Move V2 traits (may merge into agent/mod.rs)
+mv agent_v2/traits.rs agent/traits_v2.rs
+
+# Move collect helper
+mv agent_v2/collect.rs agent/collect.rs
+```
+
+**Step 2: Update agent/impls/mod.rs**
+
+Edit to export from the new location:
+
+```rust
+mod db_agent;
+pub use db_agent::{DatabaseAgent, DatabaseAgentBuilder};
+// Remove old exports if any
+```
+
+Note: File names and structure may vary. Adjust based on actual file contents.
+
+**Step 3: Commit the move**
+
+```bash
+git add -A
+git commit -m "refactor: move V2 agent files to primary locations"
+```
+
+---
+
+### Task E2.5.3: Rename V2 types (remove V2 suffix)
+
+**Files:**
+- Modify: `crates/pattern_core/src/agent/impls/db_agent.rs`
+- Modify: `crates/pattern_core/src/agent/traits_v2.rs` (or wherever AgentV2 trait is)
+- Modify: `crates/pattern_core/src/agent/collect.rs`
+
+**Step 1: In db_agent.rs, rename:**
+- `DatabaseAgentV2` → `DatabaseAgent`
+- `DatabaseAgentV2Builder` → `DatabaseAgentBuilder`
+
+Use find/replace:
+```bash
+sed -i 's/DatabaseAgentV2/DatabaseAgent/g' agent/impls/db_agent.rs
+```
+
+**Step 2: In traits file, rename:**
+- `AgentV2` → `Agent`
+- `AgentV2Ext` → `AgentExt`
+
+**Step 3: In collect.rs:**
+- Update any references to `AgentV2`
+
+**Step 4: Commit**
+
+```bash
+git add -A
+git commit -m "refactor: remove V2 suffix from agent types"
+```
+
+---
+
+### Task E2.5.4: Update agent/mod.rs exports
+
+**Files:**
+- Modify: `crates/pattern_core/src/agent/mod.rs`
+
+**Step 1: Remove old trait export, add new**
+
+Update the exports to use the new trait:
+
+```rust
+mod entity;
+mod impls;
+mod traits_v2;  // or wherever the new Agent trait is
+mod collect;
+#[cfg(test)]
+mod tests;
+pub mod tool_rules;
+
+// Export new Agent trait (was AgentV2)
+pub use traits_v2::{Agent, AgentExt};
+
+// Export new DatabaseAgent (was DatabaseAgentV2)
+pub use impls::{DatabaseAgent, DatabaseAgentBuilder};
+
+// Export collect helper
+pub use collect::collect_response;
+
+// Keep existing exports that are still valid
+pub use entity::{
+    AgentMemoryRelation, AgentRecord, SnowflakePosition,
+    get_next_message_position, get_next_message_position_string,
+    get_next_message_position_sync,
+};
+pub use tool_rules::{/* ... */};
+```
+
+**Step 2: Comment out or remove old Agent trait**
+
+If the old Agent trait was in this file, comment it out or remove it.
+
+**Step 3: Commit**
+
+```bash
+git add crates/pattern_core/src/agent/mod.rs
+git commit -m "refactor: update agent module exports for new trait"
+```
+
+---
+
+### Task E2.5.5: Update lib.rs exports
+
+**Files:**
+- Modify: `crates/pattern_core/src/lib.rs`
+
+**Step 1: Remove pub mod agent_v2**
+
+Find and remove or comment out:
+```rust
+// pub mod agent_v2;  // REMOVE THIS
+```
+
+**Step 2: Ensure agent module exports the new types**
+
+The agent module should now export `Agent`, `AgentExt`, `DatabaseAgent`.
+
+**Step 3: Run cargo check and note errors**
+
+```bash
+cargo check -p pattern_core 2>&1 | head -100
+```
+
+Expected: Many errors about trait mismatches. This is correct - we'll fix them in E3-E6.
+
+**Step 4: Commit**
+
+```bash
+git add crates/pattern_core/src/lib.rs
+git commit -m "refactor: remove agent_v2 module, use agent module for new trait"
+```
+
+---
+
+### Task E2.5.6: Document expected compilation errors
+
+**Step 1: Run cargo check and save output**
+
+```bash
+cargo check -p pattern_core 2>&1 | tee /tmp/e25-errors.txt
+```
+
+**Step 2: Categorize errors**
+
+Look for patterns:
+- "trait Agent has no method X" → Expected, fix in E3/E4
+- "struct DatabaseAgent has no field X" → Expected, fix in E3/E4
+- Missing imports → Fix now
+- Unexpected errors → Investigate
+
+**Step 3: Commit the current state**
+
+```bash
+git add -A
+git commit -m "chore: trait swap complete, compilation errors expected
+
+Errors will be fixed in E3-E6:
+- Heartbeat processor (E3)
+- Coordination patterns (E4)
+- Message queue (E5)
+- CLI/Discord (E6)
+"
+```
+
+---
+
+## E3: Update Heartbeat Processor
+
+### Task E3.1: Fix heartbeat.rs for new Agent trait
+
+**Files:**
+- Modify: `crates/pattern_core/src/context/heartbeat.rs`
+
+**Step 1: Update trait import**
+
+Change:
+```rust
+use crate::agent::{Agent, AgentState, ResponseEvent};
+```
+
+(This should now import the new slim Agent trait)
+
+**Step 2: Update process_heartbeats function signature**
+
+The agents parameter should work with new trait:
+```rust
+pub async fn process_heartbeats<F, Fut>(
+    mut heartbeat_rx: HeartbeatReceiver,
+    agents: Vec<std::sync::Arc<dyn Agent>>,  // Now uses new Agent trait
+    event_handler: F,
+)
+```
+
+**Step 3: Fix method calls on agent**
+
+Find calls to old methods and update:
+- `agent.process_message_stream()` → `agent.process()`
+- `agent.state()` → Check new signature, may be `agent.state().await`
+- `agent.name()` → Now returns `&str`, add `.to_string()` where needed
+
+**Step 4: Fix state watching**
+
+The new Agent trait has `state()` that returns `AgentState`. Check if there's a watcher mechanism. If not, adapt:
+
+```rust
+// Old: let (state, maybe_receiver) = agent.state().await;
+// New:
+let state = agent.state().await;
+// If we need to wait for Ready, we may need a different approach
+// or add state_watcher() to the trait
+```
+
+**Step 5: Run cargo check**
+
+```bash
+cargo check -p pattern_core
+```
+
+**Step 6: Commit**
+
+```bash
+git add crates/pattern_core/src/context/heartbeat.rs
+git commit -m "fix(heartbeat): update for new Agent trait"
+```
+

+
+For each file in `coordination/patterns/`:
+- dynamic.rs

+
+## Execution Notes
+
+1. **Pre-E1 and E1-E2**: Can run without breaking compilation
+2. **E2.5**: This WILL break compilation - that's expected
+3. **E3-E5**: Fix based on compiler errors, can be parallel
+4. **E6**: Depends on E3-E5 being mostly done
+5. **After each task**: Run `cargo check` to verify progress

+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Integrate DatabaseAgentV2 and AgentRuntime with the rest of the codebase - coordination patterns, built-in tools, heartbeat processor, CLI, and Discord consumers.
+
+**Depends On:** Phase D (AgentV2 trait, DatabaseAgentV2, AgentRuntime with ToolExecutor)
+
+**Outcome:** New Agent trait replaces old, RuntimeContext centralizes agent creation, CLI/Discord simplified.
+
+---
+
+## Pre-E1 Fix: ContextBuilder Missing Fields
+
+**Problem:** V2 ContextBuilder/ContextConfig is missing fields from the old ContextConfig:
+- `base_instructions` (system prompt) - exists in AgentRecord, not flowing to v2
+- Tool rules need to appear in system prompt (model must know the constraints)
+
+**Current Flow:**
+- ContextBuilder reads Core/Working blocks → system prompt
+- No explicit base_instructions field
+- Tool rules go to RuntimeBuilder → ToolExecutor (enforcement only)
+
+**Fix (do before E1):**
+1. Add to ContextBuilder:
+   - `.with_base_instructions(instructions: &str)` - prepended to system prompt
+   - `.with_tool_rules(rules: &[ToolRule])` - included in system prompt for model awareness
+2. Update `build_system_prompt()` to:
+   - Start with base_instructions if set
+   - Then render Core blocks
+   - Then render Working blocks
+   - Then append tool rules summary
+
+**Data Flow:**
+```
+AgentRecord.base_instructions ──────────────────────────────┐
+                                                            ↓
+RuntimeBuilder.tool_rules ─────→ ToolExecutor (enforcement)
+                           └───→ ContextBuilder (awareness) ─→ system prompt
+                                                            ↑
+Memory Blocks (Core/Working) ───────────────────────────────┘
+```
+
+---
+
+## Architecture Decisions
+
+### 1. MemoryStore Scoping
+- **Singleton per constellation** - One MemoryStore instance shared by all agents
+- **Agent scoping via parameter** - Methods take `agent_id: &str` to scope operations
+- **Constellation search** - `agent_id = None` searches all data in constellation DB
+- **Multi-agent search** - Run parallel single-agent searches, merge results
+
+### 2. Tool Interface: ToolContext Trait
+Tools need a defined API surface, not full AgentRuntime access.
+
+```rust
+/// What tools can access from the runtime (minimal, extensible)
+pub trait ToolContext: Send + Sync {
+    /// Current agent's ID (for default scoping)
+    fn agent_id(&self) -> &str;
+
+    /// Memory store for blocks, archival, AND search (including messages)
+    fn memory(&self) -> &dyn MemoryStore;
+
+    /// Message router for send_message
+    fn router(&self) -> &AgentMessageRouter;
+
+    /// Model provider for tools that need LLM calls
+    fn model(&self) -> &dyn ModelProvider;
+}
+```
+
+AgentRuntime implements `ToolContext`. Tools receive `Arc<dyn ToolContext>`.
+
+### 3. Search with Explicit Scope and Permissions
+
+Single search method with `SearchScope` parameter enables permission checks:
+
+```rust
+pub enum SearchScope {
+    CurrentAgent,              // Default - search own data (always allowed)
+    Agent(AgentId),            // Specific agent (permission check)
+    Agents(Vec<AgentId>),      // Multiple agents (permission check each)
+    Constellation,             // All data in constellation DB (permission check)
+}
+
+pub trait ToolContext: Send + Sync {
+    // ... core methods ...
+
+    /// Search with explicit scope - enables permission checks
+    async fn search(
+        &self,
+        query: &str,
+        scope: SearchScope,
+        options: SearchOptions,  // Existing type from memory_v2/types.rs
+    ) -> MemoryResult<Vec<MemorySearchResult>>;
+}
+```
+
+Permission checks based on scope:
+- `CurrentAgent`: Always allowed
+- `Agent(id)`: Check if current agent has permission to search that agent's data
+- `Constellation`: Check if current agent has constellation-wide search permission
+
+MemoryStore methods take `Option<&str>` for agent_id, ToolContext's search method handles scope → agent_id translation with permission checks.
+
+### 4. StateWatcher in AgentV2
+AgentV2 needs state watching capability for heartbeat processor and other consumers.
+
+**Add to AgentV2 trait or DatabaseAgentV2:**
+```rust
+/// Subscribe to state changes
+async fn state_watcher(&self) -> watch::Receiver<AgentState>;
+```
+
+Or expose via a method that returns both current state and watcher:
+```rust
+async fn state_with_watcher(&self) -> (AgentState, watch::Receiver<AgentState>);
+```
+
+This preserves the existing heartbeat processor pattern - wait for Ready state before processing continuation.
+
+### 5. Trait Swap Strategy (After E2)
+
+After E2, V2 core is complete. Rather than maintaining parallel traits, we swap:
+
+1. **Move old files out of source tree** (don't delete yet - reference if needed)
+   - `agent/impls/db_agent.rs` → `agent/impls/db_agent_v1.rs.bak`
+   - `context/state.rs` (AgentHandle) → backup
+   - Old `Agent` trait definition → backup
+
+2. **Rename V2 files/modules/traits** (remove v2 suffix)
+   - `agent_v2/` → merge into `agent/`
+   - `AgentV2` trait → `Agent`
+   - `DatabaseAgentV2` → `DatabaseAgent`
+   - `AgentV2Ext` → `AgentExt`
+   - `ToolContext` stays as-is (new name)
+
+3. **Expect compilation failures** - this is the guide
+   - Errors like "trait Agent has no method X" = expected, fix them
+   - Errors that aren't trait incompatibility = investigate carefully
+
+4. **Fix consumers in order** (E3-E6)
+   - Each fix resolves more compilation errors
+   - When `cargo check` passes, swap is complete
+
+This is cleaner than maintaining two parallel implementations through E3-E6.

+3. Add `search()` method to ToolContext with scope-based permission checks
+4. Implement `ToolContext` for `AgentRuntime`
+5. Add method to get `Arc<dyn ToolContext>` from runtime

+- Modify: `crates/pattern_core/src/tool/builtin/send_message.rs`
+- Modify: `crates/pattern_core/src/tool/builtin/mod.rs`
+
+**Changes per tool:**
+
+| Tool | AgentHandle Usage | ToolContext Equivalent |
+|------|-------------------|----------------------|
+| context | `handle.memory.get_block()` | `ctx.memory().get_block(ctx.agent_id(), name)` |
+| context | `handle.memory.alter_block()` | `ctx.memory().alter_block(ctx.agent_id(), ...)` |

+2. Update tool constructors (new factory in mod.rs)
+3. Update each tool's execute methods
+4. Update tests with mock ToolContext
+
+**Acceptance:**
+- All 4 tools compile with ToolContext
+- Existing functionality preserved
+- Tests pass
+
+---
+
+### Task E2.5: Trait Swap
+
+**Goal:** Remove V2 suffix, make new traits the primary implementation. Compilation will break - that's expected.
+
+**Step 1: Backup old files** (move out of source tree, keep for reference)
+```bash
+# In crates/pattern_core/src/
+mv agent/impls/db_agent.rs agent/impls_old/db_agent.rs
+mv context/state.rs context/state_v1.rs.bak  # AgentHandle lives here
+# Old Agent trait definition - identify file and backup
+```
+
+**Step 2: Rename V2 modules/files**
+```bash
+# Merge agent_v2 into agent
+mv agent_v2/db_agent.rs agent/db_agent.rs
+mv agent_v2/traits.rs agent/traits.rs  # or merge into mod.rs
+mv agent_v2/collect.rs agent/collect.rs
+# Update agent/mod.rs to export from new locations
+```
+
+**Step 3: Rename types** (in the moved files)
+- `AgentV2` → `Agent`
+- `DatabaseAgentV2` → `DatabaseAgent`
+- `AgentV2Ext` → `AgentExt`
+- Update all `use` statements accordingly
+
+**Step 4: Update lib.rs exports**
+- Remove `pub mod agent_v2`
+- Ensure `agent` module exports the new types
+
+**Step 5: Run cargo check, note errors**
+- Expected: "trait Agent has no method process_message_stream"
+- Expected: "struct DatabaseAgent has no field X"
+- Unexpected errors = investigate before proceeding
+
+**Acceptance:**
+- Old files backed up (not deleted)
+- V2 suffix removed from all types
+- `cargo check` fails with expected trait incompatibility errors
+- No unexpected errors (missing dependencies, etc.)
+
+---
+
+### Task E3: Update Heartbeat Processor
+
+**Files:**
+- Modify: `crates/pattern_core/src/context/heartbeat.rs`
+
+**Changes:**
+1. Update type: `Vec<Arc<dyn Agent>>` (now uses new slim trait)
+2. Replace `process_message_stream()` with `process()`
+3. Use `state_watcher()` or `state_with_watcher()` method (preserved from V1 pattern)
+4. Handle `name()` returning `&str` (add `.to_string()` where needed)
+
+**Acceptance:**
+- Heartbeat works with new `DatabaseAgent` (slim trait)
+- StateWatcher pattern preserved
+- Continuation messages process correctly
+
+---
+
+### Task E4: Update Coordination Patterns
+
+**Files (12 total):**
+- `coordination/groups.rs` - Types and GroupManager trait
+- `coordination/types.rs` - CoordinationPattern enum
+- `coordination/patterns/dynamic.rs`
+- `coordination/patterns/round_robin.rs`
+- `coordination/patterns/supervisor.rs`
+- `coordination/patterns/voting.rs`
+- `coordination/patterns/pipeline.rs`
+- `coordination/patterns/sleeptime.rs`
+- `coordination/selectors/random.rs`
+- `coordination/selectors/capability.rs`
+- `coordination/selectors/load_balancing.rs`
+- `coordination/selectors/supervisor.rs`
+
+**After E2.5 trait swap:** Only one `Agent` trait exists. Update all coordination code to use the new trait signature.
+
+**Changes per file:**
+- Replace `process_message_stream()` with `process()`
+- Handle `name()` → `&str` (add `.to_string()` where needed)
+- Update type bounds to use new `Agent` trait
+
+**Acceptance:**
+- All 6 patterns work with new `Agent` trait
+- All 4 selectors work with new `Agent` trait
+- Groups can contain agents
+
+---
+
+### Task E5: Port QueuedMessage/ScheduledWakeup to pattern_db
+
+**Files:**
+- Create: `crates/pattern_db/src/models/wakeup.rs`
+- Create: `crates/pattern_db/src/queries/wakeup.rs`
+- Create: `crates/pattern_db/migrations/NNNN_scheduled_wakeups.sql`
+- Modify: `crates/pattern_db/src/models/message.rs` (align QueuedMessage)
+- Modify: `crates/pattern_core/src/message_queue.rs` (use pattern_db)
+
+**Schema additions:**
+```sql
+-- ScheduledWakeup table
+CREATE TABLE scheduled_wakeups (
+    id TEXT PRIMARY KEY,
+    agent_id TEXT NOT NULL,
+    scheduled_for TEXT NOT NULL,
+    reason TEXT NOT NULL,
+    recurring_seconds INTEGER,
+    active INTEGER NOT NULL DEFAULT 1,
+    created_at TEXT NOT NULL,
+    last_triggered TEXT,
+    metadata TEXT,
+    FOREIGN KEY (agent_id) REFERENCES agents(id)
+);
+CREATE INDEX idx_wakeups_due ON scheduled_wakeups(scheduled_for) WHERE active = 1;
+
+-- QueuedMessage alignment (add missing fields)
+ALTER TABLE queued_messages ADD COLUMN call_chain TEXT;  -- JSON array
+ALTER TABLE queued_messages ADD COLUMN from_user TEXT;
+ALTER TABLE queued_messages ADD COLUMN read INTEGER NOT NULL DEFAULT 0;
+ALTER TABLE queued_messages ADD COLUMN read_at TEXT;
+```
+
+**Steps:**
+1. Add SQLite migration
+2. Create wakeup model and queries in pattern_db
+3. Align QueuedMessage fields between pattern_core and pattern_db
+4. Update message_queue.rs to use pattern_db queries instead of Entity/SurrealDB
+
+**Acceptance:**
+- ScheduledWakeup persists to SQLite
+- QueuedMessage call_chain preserved
+- No Entity macro usage
+
+---
+
+### Task E6: Update CLI and Discord Consumers
+
+**Files:**
+- Modify: `crates/pattern_cli/src/agent_ops.rs`
+- Modify: `crates/pattern_cli/src/chat.rs`
+- Modify: `crates/pattern_cli/src/discord.rs`
+- Modify: `crates/pattern_discord/src/bot.rs`
+
+**Key Issues Found (from exploration):**
+
+**CLI (`agent_ops.rs`):**
+- `create_agent()`: 350+ lines, violates single responsibility
+- `load_or_create_agent_from_member()`: 550+ lines with deeply nested conditionals
+- Memory block update logic duplicated 3 times
+- Model resolution has 4-level implicit priority (CLI > config > stored > default)
+- Bluesky endpoint setup called in 3 different places
+- Constellation activity block has SurrealDB bug workaround
+
+**Discord (`bot.rs`):**
+- Dual-mode `DiscordBot` with `cli_mode` hack - carries unused fields
+- 11 separate `Arc<Mutex>` for what should be one state machine
+- Config parsing explosion with fallback chains (100+ lines duplicated)
+- Two `process::exit()` calls, async leakage
+- Heartbeat channel created twice (one unused)
+
+**What Should Move to pattern_core (new `RuntimeContext`):**
+```rust
+/// Shared context for creating/loading agents with consistent defaults
+pub struct RuntimeContext {
+    db: Arc<ConstellationDb>,
+    model_provider: Arc<dyn ModelProvider>,
+    embedding_provider: Option<Arc<dyn EmbeddingProvider>>,
+    memory_store: Arc<dyn MemoryStore>,  // Constellation-scoped, shared
+    default_config: RuntimeConfig,
+}
+
+impl RuntimeContext {
+    pub fn builder() -> RuntimeContextBuilder;
+
+    /// Load from DB record, apply context defaults
+    pub async fn load_agent(&self, agent_id: &AgentId) -> Result<Arc<dyn Agent>>;
+
+    /// Load with per-agent overrides (model, tools, etc.)
+    pub async fn load_agent_with(
+        &self,
+        agent_id: &AgentId,
+        overrides: impl Into<AgentOverrides>,
+    ) -> Result<Arc<dyn Agent>>;
+
+    /// Create new agent from config (persists to DB)
+    pub async fn create_agent(&self, config: &AgentConfig) -> Result<Arc<dyn Agent>>;
+
+    /// Load group - agents share this context's stores
+    pub async fn load_group(&self, agent_ids: &[AgentId]) -> Result<Vec<Arc<dyn Agent>>>;
+}
+
+/// Per-agent overrides, cascades: context defaults → DB stored config → overrides
+pub struct AgentOverrides {
+    pub model_id: Option<String>,
+    pub response_options: Option<ResponseOptions>,
+    pub tool_rules: Option<Vec<ToolRule>>,
+    // ... other overridable fields
+}
+```
+
+**Config Resolution:**
+```
+1. Start with RuntimeContext.default_config
+2. If DB has stored config → overlay that
+3. If overrides provided → overlay those
+```
+
+- Nothing in DB → use defaults
+- Stuff in DB → use that
+- Overrides provided → use those (highest priority)
+
+**Config File → Overrides:**
+When user provides a config file but agent exists in DB:
+1. Load stored config from DB
+2. Load config from file
+3. Diff them → differences become overrides
+4. Apply overrides on load
+
+**Storage (pattern_db Agent model already has this):**
+```rust
+pub struct Agent {
+    pub system_prompt: String,                    // Base instructions
+    pub config: Json<serde_json::Value>,          // All settings as JSON
+    pub tool_rules: Option<Json<serde_json::Value>>, // Tool rules
+    pub enabled_tools: Json<Vec<String>>,         // Enabled tool names
+    // ...
+}
+```
+
+- On `create_agent()`: serialize settings → store in `config` field
+- On `load_agent()`: deserialize `config` → overlay on defaults
+- File config diffed against DB config → becomes overrides
+
+**Steps:**
+
+1. **Create RuntimeContext in pattern_core** (`runtime/context.rs`):
+   - Holds shared resources (db, providers, memory_store)
+   - Holds default_config (RuntimeConfig)
+   - `load_agent()` / `load_agent_with()` / `create_agent()` / `load_group()`
+   - Config resolution: defaults → DB → overrides
+   - Bridge PatternConfig → RuntimeConfig
+
+2. **Simplify CLI agent_ops.rs**:
+   - Replace 350-line `create_agent()` with `RuntimeContext::create_agent()`
+   - Replace load functions with `RuntimeContext::load_agent()`
+   - Config file → overrides via diff
+   - Remove duplicated memory block logic
+   - Remove duplicated Bluesky endpoint setup
+
+3. **Simplify Discord bot.rs**:
+   - Remove `cli_mode` hack (separate struct or just use RuntimeContext)
+   - Replace 11 `Arc<Mutex>` with proper state machine
+   - Use RuntimeContext for agent loading
+
+4. **Update group setup**:
+   - Use `RuntimeContext::load_group()` for shared stores
+   - Remove duplicated setup between chat.rs and discord.rs
+
+**Acceptance:**
+- CLI uses RuntimeContext (not 350-line inline code)
+- Discord uses RuntimeContext (no cli_mode hack)
+- Agent load/create is < 10 lines in consumers
+- Groups share stores properly
+- Config persists to DB, loads back correctly
+
+---

+
+---
+
+## Success Criteria
+
+- [ ] `cargo check -p pattern_core` passes
+- [ ] `cargo test -p pattern_core` passes
+- [ ] ToolContext trait defined and implemented
+- [ ] All 4 built-in tools use ToolContext
+- [ ] Heartbeat processor works with new Agent trait
+- [ ] All 6 coordination patterns work with new Agent trait
+- [ ] ScheduledWakeup in pattern_db
+- [ ] RuntimeContext created and working
+- [ ] CLI uses RuntimeContext for agent load/create
+- [ ] Discord bot uses RuntimeContext (no cli_mode hack)
+- [ ] Config persists to DB and loads correctly
+
+---
+
+## Risk Mitigation
+
+1. **Breaking changes:** Old files backed up as .bak, can restore if needed
+2. **Search scope complexity:** Start with CurrentAgent + Constellation, add multi-agent later
+3. **Compilation errors post-swap:** Expected - errors guide what to fix next
+4. **CLI/Discord complexity:** RuntimeContext centralizes logic, reduces risk of divergence
+
+---
+
+## Resolved Questions
+
+1. **Permission model for cross-agent search:**
+   - Static role-based, defined in agent's group config
+   - E.g., supervisor role has broad search permission, workers have narrow
+   - Future extension: tightly-scoped tool variants that share codebase but hide illegal operations from agent's prompt entirely
+
+2. **ToolContext extensions:**
+   - Add model provider access (tools may need LLM calls)
+   - Activity logging happens in `process()`, revisit if needed elsewhere
+
+3. **RuntimeContext lifecycle:**
+   - **One per constellation** (scoped by database)
+   - Separate constellation = separate DB = separate RuntimeContext
+   - Discord: one per init, can share across channels if permissions allow
+   - CLI hybrid mode: pass existing RuntimeContext to Discord
+   - RuntimeContext IS the constellation handle
+
+## Resolved Questions (continued)
+
+4. **Config schema versioning:**
+   - Add version field to config JSON (`config_version: u32`)
+   - Migrate on load: detect version, apply migrations to current
+   - Since we're changing config schema in this work, add migration function now
+   - Future schema changes: bump version, add migration step

+# SurrealDB Compatibility Crate Extraction Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Extract db_v1, export, and old memory types into `pattern_surreal_compat` crate to unblock Phase E integration work.
+
+**Architecture:** Create a new crate containing all SurrealDB-dependent code that Phase E is deprecating. This allows pattern_core to compile with the new V2 architecture while preserving the old code for migration tools and reference.
+
+**Tech Stack:** Rust, SurrealDB, pattern_macros Entity derive, DAG-CBOR/CAR exports
+
+---
+
+## Background
+
+Phase E is replacing SurrealDB with SQLite (via pattern_db). However, several modules still depend on:
+1. `db_v1` - SurrealDB database layer with Entity macro
+2. `export` - CAR file export/import using SurrealDB entities
+3. Old `memory.rs` - `MemoryBlock` Entity and `Memory` cache (replaced by memory/ CRDT system)
+
+Current state:
+- **E2: Tool module consolidation** - DONE (ToolContext-only)
+- **E2.5: Trait swap** - DONE (AgentV2 → Agent, DatabaseAgentV2 → DatabaseAgent)
+- 100+ compilation errors in pattern_core due to missing/moved types
+- Blocked modules: coordination/groups, data_source/*, constellation_memory, etc.
+
+Remaining Phase E tasks after this extraction:
+- E3: Heartbeat processor
+- E4: Coordination patterns
+- E5: Queue/Wakeup to pattern_db
+- E6: RuntimeContext + CLI/Discord
+
+## Files to Extract
+
+### From pattern_core/src/ (move to pattern_surreal_compat/)
+
+**db_v1/ (entire module)**
+- `mod.rs` - DatabaseBackend trait, DatabaseError, configs
+- `client.rs` - SurrealDB connection handling
+- `entity/mod.rs` - Entity trait, DbEntity
+- `entity/base.rs` - BaseTask, BaseEvent, AgentMemoryRelation
+- `migration.rs` - SurrealDB migrations
+- `ops.rs` - Query operations
+- `ops/atproto.rs` - ATProto-specific ops
+- `schema.rs` - ToolCall, EnergyLevel schemas
+
+**export/ (entire module)**
+- `mod.rs` - Export constants
+- `types.rs` - ExportManifest, AgentExport, MessageChunk, etc.
+- `exporter.rs` - AgentExporter
+- `importer.rs` - AgentImporter
+
+**From git history (main branch)**
+- `memory.rs` → `memory_v1.rs` - MemoryBlock Entity, Memory cache
+- Note: `MemoryPermission` and `MemoryType` stay in pattern_core (already in memory/mod.rs)
+
+
+## Modules to Temporarily Remove from pattern_core
+
+After extraction, these modules still won't compile due to deep V1 dependencies.
+Move them out of source tree (keep as .bak for reference):
+
+1. `constellation_memory.rs` - Uses old MemoryBlock
+2. `data_source/bluesky.rs` - Uses AgentHandle, old MemoryBlock
+3. `data_source/coordinator.rs` - Uses old MemoryBlock
+4. `data_source/file.rs` - Uses old MemoryBlock
+5. `data_source/helpers.rs` - Uses AgentHandle
+6. `data_source/homeassistant.rs` - Uses old MemoryBlock
+7. `coordination/groups.rs` - Uses AgentRecord (old entity), DbEntity trait
+8. Parts of `agent/entity.rs` - Uses db_v1 helpers

+## Task Breakdown
+
+### Task 1: Create pattern_surreal_compat crate structure
+
+**Files:**
+- Create: `crates/pattern_surreal_compat/Cargo.toml`
+- Create: `crates/pattern_surreal_compat/src/lib.rs`
+
+**Step 1: Create Cargo.toml**
+
+```toml
+[package]
+name = "pattern-surreal-compat"
+version = "0.4.0"
+edition = "2021"
+description = "SurrealDB compatibility layer for Pattern (deprecated, for migration only)"
+
+[dependencies]
+# Core dependencies from pattern_core's db_v1
+surrealdb = { version = "2.0.4", features = ["kv-mem"] }
+async-trait = "0.1"
+chrono = { version = "0.4", features = ["serde"] }
+serde = { version = "1.0", features = ["derive"] }
+serde_json = "1.0"
+thiserror = "1.0"
+miette = { version = "7.0", features = ["fancy"] }
+tracing = "0.1"
+compact_str = { version = "0.8", features = ["serde"] }
+dashmap = "6.1"
+cid = "0.11"
+
+# Pattern dependencies
+pattern-macros = { path = "../pattern_macros" }
+
+[features]
+default = []
+surreal-remote = ["surrealdb/protocol-ws"]
+```
+
+**Step 2: Create initial lib.rs**
+
+```rust
+//! SurrealDB Compatibility Layer for Pattern
+//!
+//! This crate contains deprecated SurrealDB-based code preserved for:
+//! - Migration from SurrealDB to SQLite
+//! - CAR file export/import functionality
+//! - Reference during Phase E integration
+//!
+//! **Do not add new code here. This crate is in maintenance-only mode.**
+
+pub mod db;
+pub mod entity;
+pub mod export;
+pub mod memory;
+
+// Re-export key types at crate root
+pub use db::{DatabaseBackend, DatabaseConfig, DatabaseError, Query, Result as DbResult};
+pub use entity::{AgentMemoryRelation, BaseEvent, BaseTask, DbEntity};
+pub use memory::{Memory, MemoryBlock};
+```
+
+**Step 3: Run cargo check on new crate skeleton**
+
+```bash
+cargo check -p pattern-surreal-compat
+```
+
+Expected: Errors about missing modules (we'll add them next)
+
+**Step 4: Commit**
+
+```bash
+git add crates/pattern_surreal_compat/
+git commit -m "chore: create pattern_surreal_compat crate skeleton"
+```
+
+---
+
+### Task 2: Move db_v1 module
+
+**Step 1: Copy db_v1 to new crate**
+
+```bash
+cp -r crates/pattern_core/src/db_v1/* crates/pattern_surreal_compat/src/db/
+```
+
+**Step 2: Update imports in db/mod.rs**
+
+Replace `crate::` imports with either:
+- Direct imports from dependencies
+- `crate::` for items within pattern_surreal_compat
+
+Key changes:
+- `crate::embeddings::EmbeddingError` → define locally or use miette
+- `crate::id::*` → use pattern_id crate or define locally
+- `crate::memory::MemoryPermission` → will be in crate::memory
+
+**Step 3: Fix compilation errors iteratively**
+
+```bash
+cargo check -p pattern-surreal-compat 2>&1 | head -30
+```
+
+Fix import paths until module compiles.
+
+**Step 4: Commit**
+
+```bash
+git add crates/pattern_surreal_compat/src/db/
+git commit -m "feat(surreal-compat): add db module from pattern_core/db_v1"
+```
+
+---
+
+### Task 3: Move entity module
+
+**Step 1: Copy entity submodule**
+
+```bash
+cp -r crates/pattern_core/src/db_v1/entity/* crates/pattern_surreal_compat/src/entity/
+```
+
+**Step 2: Update imports**
+
+The entity module depends on:
+- `crate::id::*` - ID types
+- `crate::memory::MemoryPermission` - permission enum
+- `crate::users::User` - user entity
+- `crate::agent::AgentRecord` - agent entity
+
+These need to either:
+- Be defined locally in pattern_surreal_compat
+- Be imported from pattern_core (creates circular dep - avoid)
+- Be stubbed out
+
+For now, stub or copy necessary types.
+
+**Step 3: Compile and fix**
+
+```bash
+cargo check -p pattern-surreal-compat
+```
+
+**Step 4: Commit**
+
+```bash
+git add crates/pattern_surreal_compat/src/entity/
+git commit -m "feat(surreal-compat): add entity module"
+```
+
+---
+
+### Task 4: Restore memory.rs from git history
+
+**Step 1: Extract old memory.rs**
+
+```bash
+git show main:crates/pattern_core/src/memory.rs > crates/pattern_surreal_compat/src/memory.rs
+```
+
+**Step 2: Rename MemoryPermission/MemoryType if needed**
+
+The new pattern_core/memory/ has its own `MemoryPermission` and `MemoryType`.
+Check if they're compatible - if so, we can re-export from pattern_core.
+If not, keep local copies with a suffix like `MemoryPermissionV1`.
+
+**Step 3: Update imports**
+
+- `crate::MemoryId` → define locally or import from pattern_id
+- `crate::UserId` → same
+- `pattern_macros::Entity` → import from pattern_macros
+
+**Step 4: Compile and fix**
+
+**Step 5: Commit**
+
+```bash
+git add crates/pattern_surreal_compat/src/memory.rs
+git commit -m "feat(surreal-compat): restore MemoryBlock entity from main branch"
+```
+
+---
+
+### Task 5: Move export module
+
+**Step 1: Copy export module**
+
+```bash
+cp -r crates/pattern_core/src/export/* crates/pattern_surreal_compat/src/export/
+```
+
+**Step 2: Update types.rs imports**
+
+The export module references:
+- `crate::AgentId` - ID type
+- `crate::agent::AgentRecord` - agent entity (needs stub or copy)
+- `crate::message::Message` - message entity
+- `crate::context::CompressionStrategy` - config type
+- `crate::config::ToolRuleConfig` - tool rules
+- `crate::coordination::groups::*` - group types
+
+This is the most complex module. Options:
+1. Stub out complex types we don't need for export
+2. Copy necessary types
+3. Make export a separate crate with optional deps
+
+For now, stub complex types and focus on compiling.
+
+**Step 3: Compile and fix iteratively**
+
+**Step 4: Commit**
+
+```bash
+git add crates/pattern_surreal_compat/src/export/
+git commit -m "feat(surreal-compat): add export module"
+```
+
+---
+
+### Task 6: Add ID types
+
+The db_v1 and entity modules need ID types. Options:
+
+1. **Create pattern_id crate** (cleanest, but more work)
+2. **Copy ID definitions** into pattern_surreal_compat
+3. **Import from pattern_core** (may work if id module doesn't depend on broken code)
+
+**Check pattern_core id module:**
+
+```bash
+cargo check -p pattern-core --lib 2>&1 | grep "id::" | head -10
+```
+
+If id module compiles independently, we can import from pattern_core.
+
+**Step 1: Decide approach based on check results**
+
+**Step 2: Implement chosen approach**
+
+**Step 3: Commit**
+
+---
+
+### Task 7: Remove broken modules from pattern_core
+
+After extraction, temporarily move non-compiling modules out of source tree:
+
+**Step 1: Backup broken modules**
+
+```bash
+cd crates/pattern_core/src
+
+# Data sources that need AgentHandle/old MemoryBlock
+mkdir -p data_source.bak
+mv data_source/bluesky.rs data_source.bak/
+mv data_source/coordinator.rs data_source.bak/
+mv data_source/file.rs data_source.bak/
+mv data_source/helpers.rs data_source.bak/
+mv data_source/homeassistant.rs data_source.bak/
+
+# Constellation memory
+mv constellation_memory.rs constellation_memory.rs.bak
+
+# Keep data_source/mod.rs but comment out broken modules
+```
+
+**Step 2: Update data_source/mod.rs**
+
+Comment out broken module declarations:
+
+```rust
+// Temporarily disabled - pending Phase E completion
+// mod bluesky;
+// mod coordinator;
+// mod file;
+// mod helpers;
+// mod homeassistant;
+
+mod cursor_store;
+mod trait_def;
+// ... keep working modules
+```
+
+**Step 3: Update lib.rs if needed**
+
+Comment out broken module exports.
+
+**Step 4: Run cargo check**
+
+```bash
+cargo check -p pattern-core
+```
+
+Goal: Reduce errors significantly. Some may remain in coordination/groups.rs etc.
+
+**Step 5: Commit**
+
+```bash
+git add -A
+git commit -m "chore: temporarily disable modules pending Phase E completion
+
+Moved to .bak:
+- data_source/{bluesky,coordinator,file,helpers,homeassistant}.rs
+- constellation_memory.rs
+
+These will be restored after Phase E integration completes."
+```
+
+---
+
+### Task 8: Handle coordination/groups.rs
+
+This module heavily uses SurrealDB entities. Options:
+
+1. **Move to pattern_surreal_compat** - if it's primarily SurrealDB code
+2. **Stub it** - if we're replacing with new implementation
+3. **Fix incrementally** - update to use pattern_db
+
+Based on Phase E plan, groups should move to new architecture. For now:
+
+**Step 1: Check what groups.rs actually does**
+
+```bash
+wc -l crates/pattern_core/src/coordination/groups.rs
+head -100 crates/pattern_core/src/coordination/groups.rs
+```
+
+**Step 2: Decide approach**
+
+If it's mostly entity definitions + CRUD → move to compat
+If it's coordination logic → keep and fix
+
+**Step 3: Implement chosen approach**
+
+**Step 4: Commit**
+
+---
+
+### Task 9: Verify pattern_core compiles
+
+**Step 1: Full check**
+
+```bash
+cargo check -p pattern-core 2>&1 | tee /tmp/check-output.txt
+```
+
+**Step 2: Count remaining errors**
+
+```bash
+grep "^error\[" /tmp/check-output.txt | wc -l
+```
+
+**Goal:** < 20 errors, all in known locations that Phase E will fix.
+
+**Step 3: Document remaining issues**
+
+Create `/tmp/remaining-issues.md` listing what still needs work.
+
+**Step 4: Commit any final fixes**
+
+---
+
+### Task 10: Add workspace member
+
+**Step 1: Update root Cargo.toml**
+
+Add pattern-surreal-compat to workspace members:
+
+```toml
+members = [
+    # ... existing
+    "crates/pattern_surreal_compat",
+]
+```
+
+**Step 2: Full workspace check**
+
+```bash
+cargo check --workspace 2>&1 | tail -20
+```
+
+**Step 3: Commit**
+
+```bash
+git add Cargo.toml
+git commit -m "chore: add pattern_surreal_compat to workspace"
+```
+
+---
+
+## Success Criteria
+
+- [ ] `pattern_surreal_compat` crate compiles
+- [ ] `pattern_core` compiles with reduced module set
+- [ ] All db_v1 code preserved in new crate
+- [ ] Export functionality preserved
+- [ ] Old MemoryBlock entity preserved
+- [ ] Broken modules backed up (not deleted)
+- [ ] < 20 remaining errors in pattern_core (all from known Phase E targets)
+
+---
+
+## Post-Extraction: Resume Phase E
+
+After this extraction, continue with remaining Phase E tasks:
+
+1. ~~**E2.5 Trait Swap**~~ - DONE
+2. **E3 Heartbeat** - fix for new Agent trait
+3. **E4 Coordination** - fix patterns for new trait (groups.rs may need special handling)
+4. **E5 Queue/Wakeup** - port to pattern_db
+5. **E6 RuntimeContext** - create and wire up
+
+**Post-E6: Additional module restoration**
+
+After core Phase E completes:
+- **E7 Data Sources** - restore and update data_source modules (bluesky, coordinator, file, helpers, homeassistant)
+- **E8 Auth/Identity** - fix oauth, atproto_identity, discord_identity modules
+
+The compat crate remains available for:
+- Migration scripts (SurrealDB → SQLite)
+- CAR export/import (if needed)
+- Reference during debugging
+
+---
+
+## Notes
+
+- Do NOT delete .bak files until Phase E is complete and tested
+- The compat crate is deprecated - no new features
+- ID types may need their own crate eventually (pattern_id)
+- Export module is complex - may need further refactoring later

+# Phase E Completion Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Complete the v2 agent infrastructure by wiring shared memory blocks, adding queue polling, creating RuntimeContext for centralized agent construction, simplifying CLI/Discord consumers, and adding error recovery and activity tracking.
+
+**Architecture:**
+- SharedBlockAttachment allows constellation-level memory blocks accessible by multiple agents via permission-gated access
+- Queue infrastructure replaces SurrealDB live queries with polling tasks for message queue and scheduled wakeups
+- RuntimeContext centralizes agent loading/creation, spawns shared infrastructure (heartbeat, queue polling)
+- Error recovery ports the battle-tested recovery logic from v1 to handle API quirks gracefully
+- Activity tracking renders recent constellation activity as a read-only system prompt section
+
+**Tech Stack:** Rust, SQLite (pattern_db), Tokio async, DashMap for concurrent state
+
+---
+
+## Part 1: SharedBlockAttachment Wiring
+
+### Task 1.1: Add shared block queries to pattern_db
+
+**Files:**
+- Modify: `crates/pattern_db/src/queries/memory.rs`
+
+**Step 1: Add query to get blocks shared with an agent**
+
+Add to end of `crates/pattern_db/src/queries/memory.rs`:

+### Task 1.2: Extend MemoryStore trait for shared blocks
+
+**Files:**
+- Modify: `crates/pattern_core/src/memory/store.rs`
+
+**Step 1: Add shared block methods to MemoryStore trait**
+
+Add to the `MemoryStore` trait after the search methods:

+### Task 1.3: Implement shared block methods in MemoryCache
+
+**Files:**
+- Modify: `crates/pattern_core/src/memory/cache.rs`
+
+**Step 1: Add imports at top of file**
+
+Add `SharedBlockInfo` to the imports from memory module.
+
+**Step 2: Implement list_shared_blocks**

+### Task 1.4: Update ContextBuilder to include shared blocks
+
+**Files:**
+- Modify: `crates/pattern_core/src/context/builder.rs`
+
+**Step 1: Extend build_system_prompt to include shared blocks**
+
+In the `build_system_prompt` method, after rendering owned blocks, add:

+
+### Task 5.2: Integrate ActivityRenderer into ContextBuilder
+
+**Files:**
+- Modify: `crates/pattern_core/src/context/builder.rs`
+
+**Step 1: Add activity rendering to build_system_prompt**

+
+## Part 6: CLI Simplification (Outline)
+
+### Task 6.1: Refactor CLI to use RuntimeContext
+
+**Files:**
+- Modify: `crates/pattern_cli/src/main.rs` or equivalent
+
+**Overview:**
+
+The CLI currently has 350+ line functions for agent setup. Refactor to:
+
+1. Create `RuntimeContext` with database connection and model + embedding providers
+2. Use `RuntimeContext` functions to create agents from config/load agents from database
+3. Remove manual agent construction code
+4. Remove `cli_mode` hack by using proper endpoint registration
+
+This task requires understanding the current CLI structure - the exact changes depend on how the CLI is currently organized.
+
+**Step 1: Identify agent creation code in CLI**
+
+Find all places where agents are constructed manually.
+
+**Step 2: Replace with RuntimeContext.load_agent()**
+
+Use the new centralized loading.
+
+**Step 3: Update endpoint registration**
+
+Use the runtime's built-in endpoint management.
+
+
+**Step 4: Commit**
+
+```bash
+git add crates/pattern_cli/
+git commit -m "refactor(cli): use RuntimeContext for agent management"
+```
+
+---
+
+## Part 7: Discord Simplification (Outline)
+
+### Task 7.1: Refactor Discord to use RuntimeContext
+
+Similar to CLI - replace manual agent construction with RuntimeContext.
+
+---
+
+## Testing Strategy
+
+Each part should be tested incrementally:
+
+1. **SharedBlockAttachment**: Write integration test that creates a constellation block, attaches it to an agent, and verifies the agent can read it in their context
+2. **Queue Infrastructure**: Write test that enqueues a message and verifies the processor picks it up
+3. **RuntimeContext**: Write test that loads an agent from DB and processes a message
+4. **Error Recovery**: Write test that triggers each error type and verifies recovery runs
+5. **Activity Tracking**: Write test that logs events and verifies they render correctly
+
+---
+
+## Verification Checklist
+
+Before considering complete:
+
+- [ ] `cargo check --workspace` passes
+- [ ] `cargo test --workspace` passes
+- [ ] `cargo sqlx prepare -p pattern_db` succeeds
+- [ ] SharedBlockAttachment test passes
+- [ ] Queue processor test passes
+- [ ] Error recovery doesn't crash on any error type
+- [ ] Activity appears in agent context
+- [ ] CLI can load and run an agent via RuntimeContext

+# RuntimeContext Config System Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Complete RuntimeContext with full agent creation, config resolution, and group loading capabilities.
+
+**Key Design Decisions:**
+- RuntimeContext owns default ModelProvider and EmbeddingProvider
+- Per-constellation SQLite database (DatabaseConfig with path)
+- Config cascade: RuntimeContext defaults → DB stored config → provided overrides
+- load_group creates agents that don't exist yet
+
+---
+
+## Part 1: Database Config for SQLite
+
+### Task 1.1: Uncomment and update DatabaseConfig
+
+**Files:**
+- Modify: `crates/pattern_core/src/config.rs`
+
+**Step 1: Add DatabaseConfig struct**
+
+Uncomment and update the DatabaseConfig (around line 46-47):
+
+```rust
+/// Database configuration for SQLite
+#[derive(Debug, Clone, Serialize, Deserialize)]
+pub struct DatabaseConfig {
+    /// Path to SQLite database file
+    pub path: PathBuf,
+}
+
+impl Default for DatabaseConfig {
+    fn default() -> Self {
+        Self {
+            path: dirs::data_dir()
+                .unwrap_or_else(|| PathBuf::from("."))
+                .join("pattern")
+                .join("constellation.db"),
+        }
+    }
+}
+```
+
+**Step 2: Add to PatternConfig**
+
+Uncomment the database field in PatternConfig:
+
+```rust
+pub struct PatternConfig {
+    // ... existing fields
+
+    /// Database configuration
+    #[serde(default)]
+    pub database: DatabaseConfig,
+
+    // ... rest
+}
+```
+
+**Step 3: Update Default impl and merge_configs**
+
+Uncomment database in Default impl and merge_configs function.
+
+**Step 4: Run cargo check**
+
+Run: `cargo check -p pattern_core`
+
+---
+
+## Part 2: AgentOverrides and ResolvedAgentConfig
+
+### Task 2.1: Add AgentOverrides struct
+
+**Files:**
+- Modify: `crates/pattern_core/src/config.rs`
+
+**Add after PartialAgentConfig:**
+
+```rust

+
+### Task 2.2: Add ResolvedAgentConfig struct

+
+---
+
+## Verification Checklist
+
+Before considering complete:
+
+- [ ] `cargo check --workspace` passes
+- [ ] DatabaseConfig uncommented and working
+- [ ] AgentOverrides and ResolvedAgentConfig defined
+- [ ] AgentConfig.to_db_agent() works
+- [ ] RuntimeContext has model_provider and embedding_provider
+- [ ] RuntimeContextBuilder works
+- [ ] create_agent persists to DB and creates memory blocks
+- [ ] load_agent_with applies overrides correctly
+- [ ] load_group creates missing agents
+- [ ] Config cascade: defaults → DB → overrides
+
+---
+
+## Testing Strategy
+
+1. **Config resolution test**: Create agent with defaults, load with overrides, verify cascade
+2. **Persistence test**: create_agent, then load_agent, verify same config
+3. **Group test**: load_group_from_config with mix of existing and new agents
+4. **Memory blocks test**: create_agent with memory config, verify blocks created

+# Auth Migration: SurrealDB → pattern-auth, atrium → Jacquard
+
+**Date:** 2025-12-26
+**Status:** Ready for implementation
+
+## Overview
+
+Migrate auth/identity infrastructure away from SurrealDB and atrium libraries toward SQLite-based pattern-auth and Jacquard. This completes the transition started with the pattern-auth crate creation.
+
+## Scope
+
+### In Scope
+1. Discord cleanup & debug command fixes
+2. BlueskyEndpoint migration from bsky-sdk to Jacquard
+3. CLI auth flow fix (agent→endpoint linking)
+4. pattern_core cleanup (remove atrium/bsky-sdk dependencies)
+
+### Out of Scope (Future Tasks)
+- Anthropic OAuth migration to pattern-auth
+- pattern_server auth rework (ATProto OAuth as identity provider)
+- Multi-user Discord OAuth linking
+
+---
+
+## Implementation Plan
+
+### Phase 1: pattern_core Cleanup
+
+**Goal:** Remove dead code and legacy dependencies before building new implementation.
+
+#### 1.1 Delete atproto_identity.rs
+- File: `crates/pattern_core/src/atproto_identity.rs`
+- Superseded by pattern-auth's Jacquard-based implementation
+- Remove from `lib.rs` exports
+
+#### 1.2 Remove Legacy Dependencies from Cargo.toml
+Remove from `crates/pattern_core/Cargo.toml`:
+- `bsky-sdk`
+- `atrium-api`
+- `atrium-oauth`
+- `atrium-common`
+- `atrium-identity`
+- `atrium-xrpc`
+
+Keep:
+- `jacquard = "0.9"`
+
+#### 1.3 Fix Compilation Errors
+- Update any remaining references to removed types
+- Ensure `cargo check` passes
+
+---
+
+### Phase 2: BlueskyEndpoint Migration
+
+**Goal:** Replace bsky-sdk with Jacquard, use pattern-auth for session storage.
+
+#### 2.1 Session Type Enum
+Create enum wrapper for OAuth vs AppPassword sessions (not dyn-compatible):
+
+```rust
+pub enum BlueskySession {
+    OAuth(OAuthSession),
+    AppPassword(CredentialSession),
+}
+```
+
+#### 2.2 BlueskyEndpoint Struct Redesign
+- Hold Jacquard client instead of bsky_sdk agent
+- Clone `AuthDb` (it's a handle, safe to clone)
+- Store agent_id for session lookup
+
+#### 2.3 Session Lookup Logic
+1. Query pattern_db `agent_atproto_endpoints` for agent-specific session
+2. If not found, fall back to `_constellation_` session
+3. Load session from auth.db by (did, session_id)
+4. Error if neither exists
+
+#### 2.4 HTTP Client Setup
+Use proper resolver with DNS and identifiable user agent:
+```rust
+JacquardResolver::new_dns(pattern_reqwest_client(), ResolverOptions::default())
+```
+
+#### 2.5 API Method Migration
+Replace bsky-sdk calls with Jacquard equivalents:
+- `create_record()` for posting
+- `get_posts()` for fetching
+- Rich text/facet handling via Jacquard types
+
+---
+
+### Phase 3: CLI Auth Flow Fix
+
+**Goal:** Properly link authenticated sessions to agents.
+
+#### 3.1 Login Flow Enhancement
+- Accept optional agent ID parameter (default: `_constellation_`)
+- After successful auth, create agent→endpoint mapping
+- Store in pattern_db `agent_atproto_endpoints` table
+
+#### 3.2 Agent Endpoint Linking
+Table schema (already exists):
+- `agent_id` - Agent identifier or `_constellation_`
+- `did` - ATProto DID
+- `session_id` - Session identifier in auth.db
+
+#### 3.3 Verification
+- `pattern-cli atproto status` should show linked agents
+- BlueskyEndpoint should successfully load sessions via the new lookup
+
+---
+
+### Phase 4: Discord Cleanup
+
+**Goal:** Remove broken OAuth code, fix disabled debug commands.
+
+#### 4.1 Remove Broken OAuth
+- Delete: `crates/pattern_discord/src/oauth.rs`
+- Remove `pub mod oauth;` from `crates/pattern_discord/src/lib.rs`
+
+#### 4.2 Remove Unused Identity Type
+- Remove/deprecate `discord_identity.rs` from pattern_core
+- This was for user→account linking (not needed for bot auth)
+
+#### 4.3 Fix Debug Commands
+
+The Discord slash commands currently use deprecated APIs that no longer exist. This section provides detailed migration guidance.
+
+##### 4.3.1 Threading ConstellationDatabases
+
+The Discord bot needs access to `ConstellationDatabases` for database queries. Current approach uses env vars and agents list only.
+
+**Required Changes to `bot.rs`:**
+1. Add `dbs: Arc<ConstellationDatabases>` field to `DiscordBot` struct
+2. Update constructors (`new_cli_mode`, `new_full_mode`) to accept `dbs` parameter
+3. Pass `dbs` to slash command handlers
+
+**Required Changes to `slash_commands.rs`:**
+- Add `dbs: &ConstellationDatabases` parameter to handlers that need database access
+
+##### 4.3.2 API Migration Reference
+
+**Old Agent methods → New API via AgentRuntime:**
+
+| Old API | New API |
+|---------|---------|
+| `agent.list_memory_keys()` | `agent.runtime().memory().list_blocks(agent.id().as_str())` → returns `Vec<BlockMetadata>` |
+| `agent.get_memory(label)` | `agent.runtime().memory().get_block(agent.id().as_str(), label)` → returns `Option<StructuredDocument>` |
+| `agent.handle().search_archival_memories(query, limit)` | `agent.runtime().memory().search_archival(agent.id().as_str(), query, limit)` → returns `Vec<ArchivalEntry>` |
+| `agent.handle().count_archival_memories()` | Use `search_archival` with high limit, count results (or add count query) |
+| `agent.handle().search_conversations(query, ...)` | `agent.runtime().memory().search(/* with appropriate options */, query, limit)` |
+
+**Old SurrealDB ops → New pattern_db queries:**
+
+| Old API | New API |
+|---------|---------|
+| `ops::list_entities::<AgentRecord, _>(&DB)` | `pattern_db::queries::list_agents(dbs.constellation.pool())` |
+
+**Type Mappings:**
+
+| Old Type | New Type | Location |
+|----------|----------|----------|
+| `AgentRecord` | `pattern_db::models::Agent` | `pattern_db::models` |
+| `DB` (SurrealDB static) | `ConstellationDatabases` (threaded through) | `pattern_core::db` |
+

+        ...
+    }
+    Err(e) => { ... }
+}
+```
+
+##### 4.3.4 Configuration Migration
+
+**Current:** Uses env vars directly (`DISCORD_ADMIN_USERS`, `DISCORD_CHANNEL_ID`, etc.)
+
+**Target:** Use `pattern_auth::AuthDb` for Discord bot configuration:
+```rust
+// Load config from auth database
+let config = dbs.auth.get_discord_bot_config().await?;
+
+// Or for authorized users check:
+fn is_authorized_user(user_id: u64, dbs: &ConstellationDatabases) -> bool {
+    // Check against stored admin list in auth.db
+    // This allows runtime updates without env var changes
+}
+```
+
+##### 4.3.5 Files to Modify
+
+1. **`pattern_discord/src/bot.rs`:**
+   - Add `dbs: Arc<ConstellationDatabases>` field
+   - Update constructors to accept dbs
+   - Update `DiscordEventHandler` to pass dbs to handlers
+
+2. **`pattern_discord/src/slash_commands.rs`:**
+   - Add `dbs` parameter to handlers needing it
+   - Replace all `agent.list_memory_keys()` calls
+   - Replace all `agent.get_memory()` calls
+   - Replace all `agent.handle()` calls
+   - Replace `ops::list_entities` with `pattern_db::queries`
+   - Remove undefined imports (`ops`, `AgentRecord`, `DB`)
+
+3. **`pattern_discord/src/lib.rs`:**
+   - Ensure proper exports for updated types
+
+#### 4.4 Verify Bot Functionality
+- Bot startup loads config from `AuthDb::get_discord_bot_config()`
+- All existing bot functionality unchanged
+- Debug commands working with pattern-db
+
+---
+
+## Key Decisions
+
+### Session Identifier Convention
+- `_constellation_` - Canonical identifier for shared constellation-level identity
+- Agent-specific IDs for per-agent identities (future use)
+
+### Session Lookup Priority
+1. Agent-specific session (by agent_id)
+2. Constellation fallback (`_constellation_`)
+3. Error if neither found
+
+### AuthDb Cloning
+`AuthDb` is a handle and can be safely cloned. BlueskyEndpoint clones it directly rather than using Arc wrapper.
+
+### HTTP Client
+All Jacquard clients use `JacquardResolver::new_dns()` with `pattern_reqwest_client()` for:
+- DNS resolution capabilities
+- Identifiable user agent
+- Consistent HTTP behavior across Pattern
+
+---
+
+## Files Changed
+
+### Deleted
+- `crates/pattern_core/src/atproto_identity.rs`
+- `crates/pattern_discord/src/oauth.rs`
+
+### Modified
+- `crates/pattern_core/Cargo.toml` - Remove atrium/bsky-sdk deps
+- `crates/pattern_core/src/lib.rs` - Remove atproto_identity export
+- `crates/pattern_core/src/runtime/endpoints/mod.rs` - BlueskyEndpoint rewrite
+- `crates/pattern_discord/src/lib.rs` - Remove oauth module
+- `crates/pattern_cli/src/commands/atproto.rs` - Add agent linking
+
+### Unchanged
+- `crates/pattern_auth/` - Already complete, production ready
+- `crates/pattern_core/src/oauth/` - Anthropic OAuth (separate future task)
+
+---
+
+## Testing
+
+1. `cargo check` passes after each phase
+2. `pattern-cli atproto login` creates session + agent link
+3. `pattern-cli atproto status` shows linked sessions
+4. Discord bot starts and responds to commands
+5. BlueskyEndpoint can post via both OAuth and AppPassword sessions
+
+---
+
+## Future Work
+
+- Anthropic OAuth → pattern-auth migration
+- pattern_server: ATProto OAuth as user identity provider
+- Multi-user Discord OAuth linking (when multi-user becomes relevant)

+# Pattern Auth Infrastructure Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Create a standalone `pattern_auth` crate for credential/token storage, implementing Jacquard's storage traits for ATProto and providing Discord bot configuration storage.
+
+**Architecture:** Constellation-scoped auth database (`auth.db`) alongside `constellation.db`. The `pattern_auth` crate has no dependency on `pattern_core` (avoids cycles). A combined wrapper in `pattern_core` provides unified access to both databases. Jacquard traits are implemented directly on `AuthDb`.
+
+**Tech Stack:** SQLite via sqlx (same as pattern_db), Jacquard crates for ATProto trait definitions, serde for serialization.
+
+---
+
+## Overview
+
+### Current State
+- Identity types (`AtprotoIdentity`, `DiscordIdentity`, `OAuthToken`) live in `pattern_core`
+- These types mix ownership concerns (UserId) with credential storage
+- No persistent storage wired up since SurrealDB→SQLite migration
+- Discord bot config is purely env-var based
+
+### Target State
+- `pattern_auth` crate owns `auth.db` and credential storage
+- Implements Jacquard's `ClientAuthStore` (OAuth) and `SessionStore` (app-password)
+- Discord bot config storable in `auth.db` (with env-var fallback)
+- `pattern_core` provides `ConstellationDatabases` wrapper combining both DBs
+- Old identity types in pattern_core deprecated/removed after migration
+
+### Database Separation
+```
+~/.config/pattern/constellations/{name}/
+├── constellation.db    # Agent state, messages, memory (backup-safe)
+└── auth.db             # Tokens, credentials (sensitive)
+```
+
+### Dependency Graph
+```
+pattern_auth  (standalone - owns auth.db, implements Jacquard traits)
+     ↑
+pattern_db    (standalone - owns constellation.db)
+     ↑
+pattern_core  → pattern_auth + pattern_db (provides ConstellationDatabases wrapper)
+     ↑
+pattern_cli, pattern_discord, etc.
+```

+
+## Task 1: Create pattern_auth Crate Skeleton
+
+**Files:**
+- Create: `crates/pattern_auth/Cargo.toml`
+- Create: `crates/pattern_auth/src/lib.rs`
+- Create: `crates/pattern_auth/CLAUDE.md`
+- Modify: `Cargo.toml` (workspace members)
+
+**Step 1: Create directory structure**
+
+```bash
+mkdir -p crates/pattern_auth/src
+mkdir -p crates/pattern_auth/migrations
+```
+
+**Step 2: Create Cargo.toml**
+
+```toml
+[package]
+name = "pattern-auth"
+version.workspace = true
+edition.workspace = true
+authors.workspace = true

+
+[dev-dependencies]
+tokio = { workspace = true, features = ["rt-multi-thread", "macros"] }
+tempfile = "3"
+```
+
+**Step 3: Create src/lib.rs**
+
+```rust
+//! Pattern Auth - Credential and token storage for Pattern constellations.
+//!
+//! This crate provides constellation-scoped authentication storage:
+//! - ATProto OAuth sessions (implements Jacquard's `ClientAuthStore`)
+//! - ATProto app-password sessions (implements Jacquard's `SessionStore`)
+//! - Discord bot configuration
+//! - Model provider OAuth tokens
+//!
+//! # Architecture
+//!
+//! Each constellation has its own `auth.db` alongside `constellation.db`.
+//! This separation keeps sensitive credentials out of the main database,
+//! making constellation backups safer to share.
+
+pub mod db;
+pub mod error;
+
+pub use db::AuthDb;
+pub use error::{AuthError, AuthResult};
+```
+
+**Step 4: Create CLAUDE.md**
+
+```markdown
+# CLAUDE.md - Pattern Auth
+
+Credential and token storage for Pattern constellations.
+
+## Purpose
+
+This crate owns `auth.db` - a constellation-scoped SQLite database storing:
+- ATProto OAuth sessions (Jacquard `ClientAuthStore` trait)
+- ATProto app-password sessions (Jacquard `SessionStore` trait)
+- Discord bot configuration
+- Model provider OAuth tokens (Anthropic)
+
+## Key Design Decisions
+
+1. **No pattern_core dependency** - Avoids circular dependencies
+2. **Jacquard trait implementations** - Direct SQLite storage for ATProto auth
+3. **Env-var fallback** - Discord config can come from DB or environment
+4. **Constellation-scoped** - One auth.db per constellation
+
+## Jacquard Integration
+
+Implements traits from jacquard-oauth and jacquard-common:
+- `ClientAuthStore` - OAuth sessions keyed by (DID, session_id)
+- `SessionStore<SessionKey, AtpSession>` - App-password sessions
+
+## Testing
+
+```bash
+cargo test -p pattern-auth
+```
+```
+
+**Step 5: Add to workspace Cargo.toml**
+
+Add `"crates/pattern_auth"` to the workspace members list.
+
+**Step 6: Commit**
+
+```bash
+git add crates/pattern_auth Cargo.toml
+git commit -m "feat(auth): create pattern_auth crate skeleton"
+```
+
+---
+
+## Task 2: Create Error Types
+
+**Files:**
+- Create: `crates/pattern_auth/src/error.rs`
+
+**Step 1: Write error types**
+
+```rust
+//! Error types for pattern_auth.
+
+use miette::Diagnostic;
+use thiserror::Error;
+
+/// Result type for auth operations.
+pub type AuthResult<T> = Result<T, AuthError>;

+## Task 4: Implement Jacquard ClientAuthStore for OAuth Sessions
+
+**Files:**
+- Create: `crates/pattern_auth/src/atproto/mod.rs`
+- Create: `crates/pattern_auth/src/atproto/oauth_store.rs`
+- Modify: `crates/pattern_auth/src/lib.rs`
+
+**Step 1: Create atproto module**
+
+```rust
+// crates/pattern_auth/src/atproto/mod.rs
+//! ATProto authentication storage.
+//!
+//! Implements Jacquard's storage traits for ATProto OAuth and app-password sessions.
+
+pub mod oauth_store;
+pub mod session_store;
+
+pub use oauth_store::*;
+pub use session_store::*;
+```
+
+**Step 2: Implement ClientAuthStore**
+
+Reference the Jacquard trait signatures from the earlier exploration. The implementation needs to:
+- Store/retrieve `ClientSessionData` keyed by (DID, session_id)
+- Store/retrieve `AuthRequestData` keyed by state string
+- Serialize complex types (DPoP keys, scopes) to JSON
+
+```rust
+// crates/pattern_auth/src/atproto/oauth_store.rs

+## Task 10: Update CLI Auth Commands to Use New Infrastructure
+
+**Files:**
+- Modify: `crates/pattern_cli/src/commands/auth.rs`
+- Modify: `crates/pattern_cli/src/commands/atproto.rs`
+
+This task updates the CLI commands to use the new `pattern_auth` crate instead of the old stubbed-out code. The detailed implementation depends on the existing CLI structure, but the key changes are:
+
+**Step 1: Update auth.rs imports and storage**
+
+Replace:
+- Old: Database operations via `db_v1::ops`
+- New: `AuthDb` methods for provider OAuth tokens
+
+**Step 2: Update atproto.rs for Jacquard integration**
+
+Replace:
+- Old: Direct atrium usage with `AtprotoIdentity` storage
+- New: Jacquard client with `AuthDb` as storage backend
+
+```rust
+// Example usage in atproto.rs
+use pattern_auth::AuthDb;
+use jacquard::client::JacquardClient;
+
+// Create client with our storage backend
+let auth_db = AuthDb::open(constellation_path.join("auth.db")).await?;
+// refer to jacquard examples ~/Projects/jacquard/examples
+// for correct usage
+// read llms.txt in that crate and use appropriate skills
+
+// OAuth flow uses Jacquard's implementation
+// App-password flow stores session in auth.db via SessionStore trait
+```
+
+**Step 3: Commit**
+
+```bash
+git add crates/pattern_cli/src/commands/auth.rs crates/pattern_cli/src/commands/atproto.rs
+git commit -m "feat(cli): wire up auth commands to pattern_auth infrastructure"
+```
+
+---
+
+## Task 11: Deprecate Old Identity Types in pattern_core
+
+**Files:**
+- Modify: `crates/pattern_core/src/atproto_identity.rs`
+- Modify: `crates/pattern_core/src/discord_identity.rs`
+- Modify: `crates/pattern_core/src/oauth.rs`
+
+**Step 1: Add deprecation notices**
+
+Add `#[deprecated]` attributes to the old types, pointing users to the new `pattern_auth` equivalents:
+
+```rust
+#[deprecated(since = "0.X.0", note = "Use pattern_auth crate for credential storage")]
+pub struct AtprotoIdentity { ... }
+```
+
+**Step 2: Keep types temporarily for migration**
+
+The old types can remain for a transition period while consumers migrate to the new infrastructure.
+
+**Step 3: Commit**
+
+```bash
+git add crates/pattern_core/src/atproto_identity.rs crates/pattern_core/src/discord_identity.rs crates/pattern_core/src/oauth.rs
+git commit -m "chore(core): deprecate old identity types in favor of pattern_auth"
+```
+
+---
+
+## Summary
+
+This plan creates a clean separation of concerns:
+
+1. **pattern_auth** - Owns auth.db, implements Jacquard traits, stores credentials
+2. **pattern_db** - Owns constellation.db, stores agent state and messages
+3. **pattern_core** - Provides `ConstellationDatabases` wrapper, orchestrates both
+
+Key benefits:
+- Constellation backups don't contain sensitive tokens
+- Jacquard integration for ATProto is properly typed
+- Discord bot config can be database-stored or env-var based
+- Clear migration path from old to new infrastructure
+
+---
+
+**Plan complete and saved to `docs/plans/2025-12-26-pattern-auth-infrastructure.md`. Two execution options:**
+
+**1. Subagent-Driven (this session)** - I dispatch fresh subagent per task, review between tasks, fast iteration
+
+**2. Parallel Session (separate)** - Open new session with executing-plans, batch execution with checkpoints

+# Block Schema Field Permissions and Loro Integration
+
+## Overview
+
+This design adds two capabilities to StructuredDocument:
+
+1. **Field-level read_only flags** - Schema fields can be marked read-only for agents, while system/source code can still write
+2. **Loro subscription passthrough** - Expose Loro's subscription mechanism for edit watching
+
+These support the data source v2 design where sources update read-only fields (like LSP diagnostics) while agents can only edit writable fields (like configuration).
+
+---
+
+## Field-Level Read-Only Flags
+
+### Design Approach: Dual-Layer
+
+Document methods take an `is_system: bool` parameter:
+- **Agent tools pass `false`** - writes to read_only fields rejected
+- **Source/system code passes `true`** - all writes allowed
+
+This keeps both sides simple - no complex permission checking at the caller level.
+
+### Schema Changes
+
+Update `FieldDef` in `crates/pattern_core/src/memory/schema.rs`:
+
+```rust
+#[derive(Debug, Clone, Serialize, Deserialize)]
+pub struct FieldDef {
+    pub name: String,
+    pub description: String,
+    pub field_type: FieldType,
+    pub required: bool,
+    pub default: Option<serde_json::Value>,
+
+    /// If true, only system/source code can write to this field.
+    /// Agent tools should reject writes to read-only fields.
+    #[serde(default)]
+    pub read_only: bool,
+}
+```
+
+### BlockSchema Helper Method
+
+Add method to check field permissions:
+
+```rust
+impl BlockSchema {
+    /// Check if a field is read-only. Returns None if field not found or schema doesn't have fields.
+    pub fn is_field_read_only(&self, field_name: &str) -> Option<bool> {
+        match self {
+            BlockSchema::Map { fields } => {
+                fields.iter()
+                    .find(|f| f.name == field_name)
+                    .map(|f| f.read_only)
+            }
+            BlockSchema::Composite { sections } => {
+                sections.iter()
+                    .find(|(name, _)| name == field_name)
+                    .and_then(|(_, schema)| {
+                        // For composite, check if the sub-schema is entirely read-only
+                        // This is a simplification - could make sections have their own read_only flag
+                        None // Or implement section-level read_only
+                    })
+            }
+            _ => None, // Text, List, Log, Tree don't have named fields
+        }
+    }
+
+    /// Get all field names that are read-only
+    pub fn read_only_fields(&self) -> Vec<&str> {
+        match self {
+            BlockSchema::Map { fields } => {
+                fields.iter()
+                    .filter(|f| f.read_only)
+                    .map(|f| f.name.as_str())
+                    .collect()
+            }
+            _ => vec![],
+        }
+    }
+}
+```
+
+### StructuredDocument Changes
+
+#### New Error Variant
+
+```rust
+#[derive(Debug, Error)]
+pub enum DocumentError {
+    // ... existing variants ...
+
+    #[error("Field '{0}' is read-only and cannot be modified by agent")]
+    ReadOnlyField(String),
+}
+```
+
+#### Updated Method Signatures
+
+Methods that write to fields gain `is_system: bool` parameter:
+
+```rust
+impl StructuredDocument {
+    /// Set a field value. If is_system is false and field is read_only, returns error.
+    pub fn set_field(
+        &self,
+        name: &str,
+        value: impl Into<serde_json::Value>,
+        is_system: bool,
+    ) -> Result<(), DocumentError> {
+        // Check read-only if not system
+        if !is_system {
+            if let Some(true) = self.schema.is_field_read_only(name) {
+                return Err(DocumentError::ReadOnlyField(name.to_string()));
+            }
+        }
+
+        // ... existing implementation ...
+    }
+
+    /// Set a text field. If is_system is false and field is read_only, returns error.
+    pub fn set_text_field(
+        &self,
+        name: &str,
+        value: &str,
+        is_system: bool,
+    ) -> Result<(), DocumentError> {
+        if !is_system {
+            if let Some(true) = self.schema.is_field_read_only(name) {
+                return Err(DocumentError::ReadOnlyField(name.to_string()));
+            }
+        }
+        // ... existing implementation ...
+    }
+
+    /// Append to a list field. If is_system is false and field is read_only, returns error.
+    pub fn append_to_list_field(
+        &self,
+        name: &str,
+        value: impl Into<serde_json::Value>,
+        is_system: bool,
+    ) -> Result<(), DocumentError> {
+        if !is_system {
+            if let Some(true) = self.schema.is_field_read_only(name) {
+                return Err(DocumentError::ReadOnlyField(name.to_string()));
+            }
+        }
+        // ... existing implementation ...
+    }
+
+    /// Remove from a list field. If is_system is false and field is read_only, returns error.
+    pub fn remove_from_list_field(
+        &self,
+        name: &str,
+        index: usize,
+        is_system: bool,
+    ) -> Result<(), DocumentError> {
+        if !is_system {
+            if let Some(true) = self.schema.is_field_read_only(name) {
+                return Err(DocumentError::ReadOnlyField(name.to_string()));
+            }
+        }
+        // ... existing implementation ...
+    }
+
+    /// Increment a counter field. If is_system is false and field is read_only, returns error.
+    pub fn increment_counter(
+        &self,
+        name: &str,
+        delta: i64,
+        is_system: bool,
+    ) -> Result<i64, DocumentError> {
+        if !is_system {
+            if let Some(true) = self.schema.is_field_read_only(name) {
+                return Err(DocumentError::ReadOnlyField(name.to_string()));
+            }
+        }
+        // ... existing implementation ...
+    }
+}
+```
+
+#### Non-Field Operations
+
+For Text, List (non-Map), and Log schemas, there's no field-level granularity. The block-level permission applies. These methods don't need `is_system`:
+
+- `set_text()`, `append_text()`, `replace_text()` - Text schema ops
+- `push_item()`, `insert_item()`, `delete_item()` - List schema ops
+- `append_log_entry()` - Log schema ops (typically system-only anyway)
+
+### Rendering with Read-Only Indicators
+
+Update `render()` to indicate read-only fields to the agent:
+
+```rust
+impl StructuredDocument {
+    pub fn render(&self) -> String {
+        match &self.schema {
+            BlockSchema::Map { fields } => {
+                let mut output = String::new();
+                for field in fields {
+                    let value = self.get_field(&field.name)
+                        .map(|v| json_display(&v))
+                        .unwrap_or_default();
+
+                    // Mark read-only fields
+                    let marker = if field.read_only { " [read-only]" } else { "" };
+                    output.push_str(&format!("{}{}: {}\n", field.name, marker, value));
+                }
+                output
+            }
+            // ... other schemas unchanged ...
+        }
+    }
+}
+```

+
+## Loro Subscription Integration
+
+### Goals
+
+1. Allow callers to subscribe to document changes
+2. Support both container-level and root-level subscriptions
+3. Enable attribution via commit messages
+4. Ensure commits happen so subscriptions fire
+
+### Loro Background
+
+Loro provides two subscription methods:
+
+```rust
+// Subscribe to specific container
+doc.subscribe(&container_id, callback) -> Subscription
+
+// Subscribe to all changes
+doc.subscribe_root(callback) -> Subscription
+```
+
+Subscriptions fire after transactions commit. Commits happen on:
+- `doc.commit()` explicit call
+- `doc.export(mode)`
+- `doc.import(data)`
+- `doc.checkout(version)`
+
+### StructuredDocument Subscription API
+
+```rust
+use loro::{Subscriber, Subscription, ContainerID};
+
+impl StructuredDocument {
+    /// Subscribe to all changes on this document
+    pub fn subscribe_root(&self, callback: Subscriber) -> Subscription {
+        self.doc.subscribe_root(callback)
+    }
+
+    /// Subscribe to changes on a specific container
+    pub fn subscribe(&self, container_id: &ContainerID, callback: Subscriber) -> Subscription {
+        self.doc.subscribe(container_id, callback)
+    }
+
+    /// Subscribe to the main content container based on schema type
+    pub fn subscribe_content(&self, callback: Subscriber) -> Subscription {
+        let container_id = match &self.schema {
+            BlockSchema::Text => self.doc.get_text("content").id(),
+            BlockSchema::Map { .. } => self.doc.get_map("root").id(),
+            BlockSchema::List { .. } => self.doc.get_list("items").id(),
+            BlockSchema::Log { .. } => self.doc.get_list("entries").id(),
+            BlockSchema::Tree { .. } => self.doc.get_tree("tree").id(),
+            BlockSchema::Composite { .. } => {
+                // For composite, subscribe to root map
+                self.doc.get_map("root").id()
+            }
+        };
+        self.doc.subscribe(&container_id, callback)
+    }
+
+    /// Set attribution message for the next commit
+    pub fn set_attribution(&self, message: &str) {
+        self.doc.set_next_commit_message(message);
+    }
+
+    /// Explicitly commit pending changes (triggers subscriptions)
+    pub fn commit(&self) {
+        self.doc.commit();
+    }
+
+    /// Commit with attribution message
+    pub fn commit_with_attribution(&self, message: &str) {
+        self.doc.set_next_commit_message(message);
+        self.doc.commit();
+    }
+}
+```
+
+### Attribution Format
+
+For audit/logging, use structured attribution messages:
+
+```rust
+// Agent edit
+doc.set_attribution(&format!("agent:{}:field:{}", agent_id, field_name));
+
+// Source update
+doc.set_attribution(&format!("source:{}:update", source_id));
+
+// System operation
+doc.set_attribution("system:compression");
+```
+
+These can be parsed from the commit message in subscription callbacks.
+
+### Ensuring Commits
+
+Update write methods to commit after changes:
+
+```rust
+impl StructuredDocument {
+    pub fn set_field(
+        &self,
+        name: &str,
+        value: impl Into<serde_json::Value>,
+        is_system: bool,
+    ) -> Result<(), DocumentError> {
+        // ... permission check ...
+
+        // ... set the value ...
+
+        // Auto-commit so subscriptions fire
+        self.doc.commit();
+
+        Ok(())
+    }
+}
+```
+
+Or batch multiple operations before committing:
+
+```rust
+// Batch operations without auto-commit
+doc.set_field_no_commit("field1", value1, true)?;
+doc.set_field_no_commit("field2", value2, true)?;
+
+// Commit once at the end
+doc.commit_with_attribution("source:lsp:diagnostics_update");
+```
+
+### Subscription Callback Type
+
+Loro's `Subscriber` type:
+
+```rust
+pub type Subscriber = Arc<dyn Fn(DiffEvent) + Send + Sync>;
+
+pub struct DiffEvent {
+    /// Whether the change was local or from import
+    pub triggered_by: EventTriggerKind,
+    /// The actual change events
+    pub events: Vec<ContainerDiff>,
+}
+```
+
+### Example: Data Source Edit Watching
+
+```rust
+impl LspSource {
+    async fn setup_block_watching(&self, block: &StructuredDocument) {
+        let source_id = self.source_id.clone();
+        let handler = self.edit_handler.clone();
+
+        // Subscribe to the diagnostics block
+        let _sub = block.subscribe_content(Arc::new(move |event| {
+            // Only handle local edits (agent changes), not our own imports
+            if event.triggered_by.is_local() {
+                for diff in event.events {
+                    // Check which fields changed
+                    if let Some(map_diff) = diff.diff.as_map() {
+                        for (key, change) in map_diff.updated.iter() {
+                            // Route to handler
+                            handler.handle_field_edit(&source_id, key, change);
+                        }
+                    }
+                }
+            }
+        }));
+
+        // Store subscription to keep it alive
+        self.subscriptions.lock().push(_sub);
+    }
+}
+```
+
+### Example: File Source Disk Sync
+
+```rust
+impl FileSource {
+    fn setup_sync(&self, block: &StructuredDocument, path: &Path) {
+        let path = path.to_owned();
+        let debouncer = self.debouncer.clone();
+
+        let _sub = block.subscribe_root(Arc::new(move |event| {
+            if event.triggered_by.is_local() {
+                // Agent made local edits - queue disk write
+                debouncer.schedule_write(&path);
+            }
+        }));
+
+        self.subscriptions.lock().push(_sub);
+    }
+}
+```
+
+---
+
+## Integration with MemoryCache
+
+The cache may need to coordinate subscriptions:
+
+```rust
+impl MemoryCache {
+    /// Get block with subscription for edit watching
+    pub async fn get_with_subscription(
+        &self,
+        agent_id: &str,
+        label: &str,
+        callback: Subscriber,
+    ) -> Result<(StructuredDocument, Subscription), MemoryError> {
+        let doc = self.get(agent_id, label).await?;
+        let sub = doc.subscribe_root(callback);
+        Ok((doc, sub))
+    }
+}
+```
+
+Or subscriptions can be managed externally by the caller (data sources, tools, etc.).
+
+---
+
+## Summary of Changes
+
+### schema.rs
+- Add `read_only: bool` to `FieldDef`

+- Add `is_system: bool` parameter to field write methods
+- Add permission check before field writes
+- Add `subscribe_root()`, `subscribe()`, `subscribe_content()`
+- Add `set_attribution()`, `commit()`, `commit_with_attribution()`
+- Update `render()` to show read-only indicators
+
+### types.rs (if needed)
+- Could add `EditEvent` type for structured edit tracking
+
+---
+
+## Design Decisions
+
+### Text/List Schemas
+No field-level granularity needed. Block-level permission (`MemoryPermission`) handles these. The whole block is either writable or not.
+
+### Composite Schemas - Section-Level Gating
+Composite schemas need **section-level** read_only, not just field-level. Common pattern:
+- Read-only map section (source-updated diagnostics)
+- Editable text section (agent notes)
+
+Update `BlockSchema::Composite`:
+
+```rust
+pub enum BlockSchema {
+    // ... other variants ...
+
+    Composite {
+        /// Named sections with their schemas and permissions
+        sections: Vec<CompositeSection>,
+    },
+}
+
+#[derive(Debug, Clone, Serialize, Deserialize)]
+pub struct CompositeSection {
+    pub name: String,
+    pub schema: Box<BlockSchema>,
+    pub description: Option<String>,
+    /// If true, only system/source code can write to this section
+    #[serde(default)]
+    pub read_only: bool,
+}
+```
+
+Then `is_section_read_only()` checks section-level for Composite:
+
+```rust
+impl BlockSchema {
+    pub fn is_section_read_only(&self, section_name: &str) -> Option<bool> {
+        match self {
+            BlockSchema::Composite { sections } => {
+                sections.iter()
+                    .find(|s| s.name == section_name)
+                    .map(|s| s.read_only)
+            }
+            _ => None,
+        }
+    }
+
+    /// Get the schema for a section (for type checking operations)
+    pub fn get_section_schema(&self, section_name: &str) -> Option<&BlockSchema> {
+        match self {
+            BlockSchema::Composite { sections } => {
+                sections.iter()
+                    .find(|s| s.name == section_name)
+                    .map(|s| s.schema.as_ref())
+            }
+            _ => None,
+        }
+    }
+}
+```
+
+### Composite Operations - Section Key Parameter
+
+Rather than adding new methods for Composite, update existing methods to take an optional `section` parameter. This determines which Loro container to operate on.
+
+**Current hardcoded keys:**
+- Text schema: `"content"` → `doc.get_text("content")`
+- Map schema: `"root"` → `doc.get_map("root")`
+- List schema: `"items"` → `doc.get_list("items")`
+- Log schema: `"entries"` → `doc.get_list("entries")`
+
+**With section parameter:**
+```rust
+impl StructuredDocument {
+    /// Get the container key for an operation
+    fn container_key(&self, section: Option<&str>) -> &str {
+        section.unwrap_or_else(|| match &self.schema {
+            BlockSchema::Text => "content",
+            BlockSchema::Map { .. } => "root",
+            BlockSchema::List { .. } => "items",
+            BlockSchema::Log { .. } => "entries",
+            BlockSchema::Composite { .. } => {
+                // For composite without section, panic - caller must specify
+                panic!("Composite schema requires section parameter")
+            }
+        })
+    }
+
+    /// Get the effective schema for an operation (section schema for Composite)
+    fn effective_schema(&self, section: Option<&str>) -> &BlockSchema {
+        match (&self.schema, section) {
+            (BlockSchema::Composite { .. }, Some(name)) => {
+                self.schema.get_section_schema(name)
+                    .expect("Section not found in composite schema")
+            }
+            _ => &self.schema,
+        }
+    }
+}
+```
+
+**Updated method signatures:**
+
+```rust
+impl StructuredDocument {
+    // Text operations - add section parameter
+    pub fn text_content(&self, section: Option<&str>) -> String {
+        let key = self.container_key(section);
+        self.doc.get_text(key).to_string()
+    }
+
+    pub fn set_text(
+        &self,
+        content: &str,
+        section: Option<&str>,
+        is_system: bool,
+    ) -> Result<(), DocumentError> {
+        // Check section read_only for composite
+        if !is_system {
+            if let Some(name) = section {
+                if let Some(true) = self.schema.is_section_read_only(name) {
+                    return Err(DocumentError::ReadOnlySection(name.to_string()));
+                }
+            }

+        // ...
+    }
+
+    // Map operations - add section parameter
+    pub fn get_field(&self, name: &str, section: Option<&str>) -> Option<serde_json::Value> {
+        let key = self.container_key(section);
+        let map = self.doc.get_map(key);

+
+    pub fn set_field(

+        name: &str,
+        value: impl Into<serde_json::Value>,
+        section: Option<&str>,

+    ) -> Result<(), DocumentError> {
+        // Check section read_only first (for composite)
+        if !is_system {
+            if let Some(sec_name) = section {
+                if let Some(true) = self.schema.is_section_read_only(sec_name) {
+                    return Err(DocumentError::ReadOnlySection(sec_name.to_string()));
+                }
+            }
+        }
+
+        // Then check field read_only (for Map sections)
+        let effective = self.effective_schema(section);
+        if !is_system {
+            if let BlockSchema::Map { fields } = effective {
+                if let Some(field) = fields.iter().find(|f| f.name == name) {
+                    if field.read_only {
+                        return Err(DocumentError::ReadOnlyField(name.to_string()));
+                    }
+                }
+            }
+        }
+
+        let key = self.container_key(section);
+        let map = self.doc.get_map(key);
+        // ... perform operation ...
+        Ok(())
+    }
+
+    // List operations - add section parameter
+    pub fn list_items(&self, section: Option<&str>) -> Vec<serde_json::Value> {
+        let key = self.container_key(section);
+        let list = self.doc.get_list(key);
+        // ...
+    }
+
+    pub fn push_item(
+        &self,
+        value: impl Into<serde_json::Value>,
+        section: Option<&str>,
+        is_system: bool,
+    ) -> Result<(), DocumentError> {
+        // Check section read_only, then operate
+        // ...
+    }
+}
+```
+
+**New error variant:**
+```rust
+#[derive(Debug, Error)]
+pub enum DocumentError {
+    // ... existing ...
+
+    #[error("Section '{0}' is read-only and cannot be modified by agent")]
+    ReadOnlySection(String),
+}
+```
+
+**Call site updates:**
+
+Existing code using these methods needs to add `None` for the section parameter:
+
+```rust
+// Before
+doc.text_content()
+doc.set_field("key", value)
+
+// After
+doc.text_content(None)
+doc.set_field("key", value, None, is_system)
+```
+
+For composite blocks:
+```rust
+// Access a specific section
+let diagnostics = doc.get_field("errors", Some("diagnostics"))?;
+doc.set_field("filter", "warning", Some("config"), false)?;
+```
+
+### StructuredDocument Self-Identification
+
+StructuredDocument should carry its own identity for convenience (no need to pass context everywhere):
+
+```rust
+pub struct StructuredDocument {
+    doc: LoroDoc,
+    schema: BlockSchema,
+    permission: MemoryPermission,
+
+    /// Block label for identification
+    label: String,
+    /// Agent that loaded this document (for attribution)
+    accessor_agent_id: Option<String>,
+}
+
+impl StructuredDocument {
+    pub fn label(&self) -> &str {
+        &self.label
+    }
+
+    pub fn accessor_agent_id(&self) -> Option<&str> {
+        self.accessor_agent_id.as_deref()
+    }
+
+    /// Set attribution automatically based on accessor
+    pub fn auto_attribution(&self, operation: &str) {
+        if let Some(agent_id) = &self.accessor_agent_id {
+            self.set_attribution(&format!("agent:{}:{}", agent_id, operation));
+        }
+    }
+}
+```
+
+This enables tools to:
+```rust
+// Tool code
+doc.auto_attribution("set_field:severity_filter");
+doc.set_field("severity_filter", "warning", false)?;
+doc.commit();
+// Then call memory.mark_dirty() and memory.persist_block() with doc.label()
+```
+
+### Persistence Responsibility
+
+Can't enforce programmatically that callers call `mark_dirty()` / `persist_block()`, but:
+
+1. Document carries `label` and `accessor_agent_id` so callers have the info they need
+2. Tools should always have a reference to the MemoryStore that provided the document
+3. Document convention: after modifying, call `memory.mark_dirty(label)` and eventually `memory.persist_block(label)`
+
+Could add a helper that bundles both:
+
+```rust
+impl MemoryCache {
+    /// Persist a modified document (marks dirty and persists)
+    pub async fn save_document(&self, doc: &StructuredDocument) -> Result<(), MemoryError> {
+        let label = doc.label();
+        self.mark_dirty(label);
+        self.persist_block(label).await
+    }
+}
+```
+
+---
+
+## Final Design Decisions
+
+### Auto-Commit Behavior
+Write methods auto-commit. Granularity is good - each operation is atomic and triggers subscriptions immediately. No need for separate batch variants.
+
+```rust
+pub fn set_field(...) -> Result<(), DocumentError> {
+    // ... permission checks ...
+    // ... perform operation ...
+    self.doc.commit();  // Always commit
+    Ok(())
+}
+```
+
+### Subscriptions
+Entirely caller's responsibility. StructuredDocument exposes the Loro subscription methods, but doesn't manage subscription lifetime. Data sources, tools, or other callers create and hold `Subscription` handles as needed.
+
+### UndoManager Integration
+Loro provides `UndoManager` for granular undo/redo. Expose with StructuredDocument:
+
+```rust
+use loro::UndoManager;
+
+impl StructuredDocument {
+    /// Create an UndoManager for this document
+    pub fn undo_manager(&self) -> UndoManager {
+        UndoManager::new(&self.doc)
+    }
+}
+```
+
+Usage:
+```rust
+let mut undo = doc.undo_manager();
+doc.set_field("key", "value1", None, false)?;
+doc.set_field("key", "value2", None, false)?;
+undo.undo();  // Back to "value1"
+undo.redo();  // Forward to "value2"
+```
+
+This gives agents/tools fine-grained rollback without needing full version snapshots.
+
+### Tree Schema - Dropped
+Tree schema is dropped from the design. Composite covers the use cases:
+- Map with complex fields ≈ shallow tree
+- Composite with Map sections ≈ opinionated tree
+- Deep arbitrary nesting is confusing and hard to implement well
+- If path queries needed later, can port from Jacquard's value types
+
+Update `BlockSchema`:
+```rust
+pub enum BlockSchema {
+    Text,
+    Map { fields: Vec<FieldDef> },
+    List { item_schema: Option<Box<BlockSchema>>, max_items: Option<usize> },
+    Log { display_limit: usize },
+    Composite { sections: Vec<CompositeSection> },
+    // Tree removed
+}
+```

+# Data Source v2 Design
+
+## Overview
+
+This design describes a restructured data source system that fully leverages the v2 memory system's structured blocks, Loro CRDT capabilities, and permission model. The key insight is splitting data sources into two distinct trait families based on their fundamental interaction patterns.
+
+## Core Concepts
+
+### Two Source Types
+
+**DataBlock** - Persistent, document-oriented sources (files, structured configs)
+- Loro-backed with full versioning, rollback, and history
+- Bidirectional sync with external storage (disk, remote)
+- Agent works with these like documents
+
+**DataStream** - Event-driven, push-based sources (Bluesky, Discord, sensors, LSP)
+- Creates blocks from events/state
+- Mix of passive (pinned block updates) and active (notifications) patterns
+- Source subscribes to agent edits on writable fields
+
+Both produce memory blocks, but lifecycles and coordination are fundamentally different.
+
+---
+
+## DataBlock Trait
+
+> **Full details:** [2025-12-27-datablock-trait-design.md](./2025-12-27-datablock-trait-design.md)
+
+Document-oriented sources (files, configs) with Loro-backed versioning and permission-gated disk sync.
+
+### Key Points
+
+- **Loro as working state** - Agent's view with full version history and rollback
+- **Disk as canonical** - External changes (shell, editor) win via reconcile
+- **Permission-gated writes** - Glob patterns determine access levels
+- **Shell/ACP integration hooks** - Reconcile after external modifications
+
+### Sync Model
+
+```
+Agent tools ←→ Loro ←→ Disk ←→ Editor (ACP)
+                 ↑
+            Shell side effects
+```
+
+### Core Types
+
+```rust
+pub struct PermissionRule {
+    pub pattern: String,  // Glob: "src/**/*.rs"
+    pub permission: MemoryPermission,
+    pub operations_requiring_escalation: Vec<String>,
+}
+
+pub struct FileChange {
+    pub path: String,
+    pub change_type: FileChangeType,
+    pub block_id: Option<String>,
+}
+```
+
+### Trait Summary
+
+```rust
+#[async_trait]
+pub trait DataBlock: Send + Sync {
+    fn source_id(&self) -> &str;
+    fn name(&self) -> &str;
+    fn schema(&self) -> BlockSchema;
+    fn permission_rules(&self) -> &[PermissionRule];
+    fn required_tools(&self) -> Vec<ToolRule>;
+    fn matches(&self, path: &str) -> bool;
+    fn permission_for(&self, path: &str) -> MemoryPermission;
+
+    async fn load(&self, path: &str, memory: &dyn MemoryStore, owner: AgentId) -> Result<BlockRef>;
+    async fn create(&self, path: &str, content: Option<&str>, memory: &dyn MemoryStore, owner: AgentId) -> Result<BlockRef>;
+    async fn save(&self, block_ref: &BlockRef, memory: &dyn MemoryStore) -> Result<()>;
+    async fn delete(&self, path: &str, memory: &dyn MemoryStore) -> Result<()>;
+
+    fn start_watch(&mut self) -> Option<broadcast::Receiver<FileChange>>;
+    fn stop_watch(&mut self);
+    async fn reconcile(&self, paths: &[String], memory: &dyn MemoryStore) -> Result<Vec<FileChange>>;
+
+    async fn history(&self, block_ref: &BlockRef, memory: &dyn MemoryStore) -> Result<Vec<VersionInfo>>;
+    async fn rollback(&self, block_ref: &BlockRef, version: &str, memory: &dyn MemoryStore) -> Result<()>;
+    async fn diff(&self, block_ref: &BlockRef, from: Option<&str>, to: Option<&str>, memory: &dyn MemoryStore) -> Result<String>;
+}
+```
+
+---
+
+## DataStream Trait
+
+> **Full details:** [2025-12-27-datastream-trait-design.md](./2025-12-27-datastream-trait-design.md)
+
+Event-driven sources (Bluesky, Discord, LSP, sensors) that produce notifications and manage state blocks.
+
+### Key Points
+
+- **No generics** - Type safety at source boundary, flexible routing at trait level
+- **Channel-based** - Source emits `Notification` on broadcast channel
+- **Blocks persist, context is filtered** - Ephemeral blocks drop out of context, not deleted
+- **Source manages blocks** - Gets `Arc<dyn MemoryStore>` on `start()`, creates/updates blocks directly
+
+### Block Lifecycle
+
+| Type | Behavior |
+|------|----------|
+| Pinned (`pinned=true`) | Always in context while subscribed |
+| Ephemeral (`pinned=false`) | Loaded for batch that references them, then drops out |
+
+Agent can `load` (temporary peek), `pin` (persistent), or `unpin` (make ephemeral).
+
+### Core Types
+
+```rust
+pub struct Notification {
+    pub message: Message,              // Full Message (multi-modal)
+    pub block_refs: Vec<BlockRef>,     // Blocks to load for this batch
+    pub batch_id: SnowflakePosition,
+}
+
+pub struct BlockRef {
+    pub label: String,
+    pub block_id: String,
+    pub agent_id: String,  // Owner, defaults to "_constellation_"
+}
+```
+
+### Trait Summary
+
+```rust
+#[async_trait]
+pub trait DataStream: Send + Sync {
+    fn source_id(&self) -> &str;
+    fn name(&self) -> &str;
+    fn block_schemas(&self) -> Vec<BlockSchemaSpec>;
+    fn required_tools(&self) -> Vec<ToolRule>;
+
+    async fn start(&mut self, memory: Arc<dyn MemoryStore>, owner: AgentId)
+        -> Result<broadcast::Receiver<Notification>>;
+    async fn stop(&mut self) -> Result<()>;
+
+    fn pause(&mut self);
+    fn resume(&mut self);
+    fn is_paused(&self) -> bool;
+
+    fn supports_pull(&self) -> bool { false }
+    async fn pull(&self, limit: usize, cursor: Option<StreamCursor>)
+        -> Result<Vec<Notification>> { Ok(vec![]) }
+}
+```
+
+---
+
+## Block Editing Tools
+
+### Tool Taxonomy (Consolidated Modal Design)
+
+**`block_edit` tool** - Edit block content (capability-gated operations)
+```
+block_edit(block_label, op: append | replace | patch | set_field, content?, field?, position?)
+```
+
+| Operation | Description | Capability Level |
+|-----------|-------------|------------------|
+| `append` | Append to text/list content | Basic |
+| `replace` | Basic text replacement | Basic |
+| `patch` | Apply diff/patch operations | Advanced |
+| `set_field` | Schema-aware field edit (Map/Composite) | Medium |
+
+**`block` tool** - Block lifecycle management
+```
+block(label, op: load | pin | unpin | archive | info)
+```
+
+| Operation | Description |
+|-----------|-------------|
+| `load` | Load a block into working memory |
+| `pin` | Pin block to retain in context |
+| `unpin` | Unpin block (will fade after request) |
+| `archive` | Move to archival storage |
+| `info` | Get block metadata/schema info |
+
+**`recall` tool** - Archival memory (simplified)
+```
+recall(op: search | get, query?, entry_id?)
+```
+Works with immutable archival entries only. Search and retrieve, no edit operations.
+
+**`source` tool** - Data source control
+```
+source(source_id, op: pause | resume | status)
+```
+
+| Operation | Description |
+|-----------|-------------|
+| `pause` | Pause notifications from a source |
+| `resume` | Resume notifications |
+| `status` | Check source status |
+
+### Dynamic Tool Registration
+
+When a block is loaded, check its schema and enable appropriate operations:
+
+```rust
+impl ContextBuilder {
+    fn load_block(&mut self, block: &CachedBlock) {
+        // Enable block_edit tool with operations based on schema
+        let allowed_ops = match block.schema() {
+            BlockSchema::Map { .. } | BlockSchema::Composite { .. } => {
+                // Structured blocks get set_field operation
+                vec![Append, Replace, SetField]
+            }
+            BlockSchema::Text => {
+                vec![Append, Replace]
+            }
+            BlockSchema::List { .. } => {
+                vec![Append]
+            }
+            // etc.
+        };
+
+        // Add patch if agent has advanced capability
+        if self.agent_capabilities.contains(Capability::AdvancedEdit) {
+            allowed_ops.push(Patch);
+        }
+
+        self.tool_registry.register(block_edit_tool(ops: allowed_ops));
+    }
+}
+```
+
+Block rendering includes hints for agent:
+- Schema type and structure
+- Available operations based on permissions
+- Read-only field indicators
+
+---
+
+## Coordinator Changes
+
+The `DataIngestionCoordinator` manages both source types:
+
+```rust
+pub struct DataIngestionCoordinator {
+    block_sources: DashMap<String, Arc<dyn DataBlock>>,
+    stream_sources: DashMap<String, Arc<dyn DataStream>>,
+
+    // Subscription tracking
+    agent_block_subscriptions: DashMap<AgentId, Vec<BlockSubscription>>,
+    agent_stream_subscriptions: DashMap<AgentId, Vec<StreamSubscription>>,
+
+    // Block edit subscribers (source -> block patterns it cares about)
+    block_edit_subscribers: DashMap<String, Vec<BlockEditSubscriber>>,
+}
+
+impl DataIngestionCoordinator {
+    /// Subscribe agent to a stream source
+    pub async fn subscribe_to_stream(
+        &self,
+        agent_id: &AgentId,
+        source_id: &str,
+    ) -> Result<()> {
+        let source = self.stream_sources.get(source_id)?;
+
+        // Create pinned blocks
+        let state = source.on_subscribe(agent_id).await?;
+
+        // Register required tools
+        for tool in source.required_tools() {
+            self.tool_registry.register_for_agent(agent_id, tool);
+        }
+
+        // Subscribe source to block edits
+        self.register_block_edit_subscriber(source_id, source.pinned_block_schemas());
+
+        // Start monitoring if provides notifications
+        if source.provides_notifications() {
+            self.spawn_stream_monitor(agent_id, source_id);
+        }
+
+        Ok(())
+    }
+
+    /// Handle block edit - route to interested sources
+    pub async fn handle_block_edit(&self, edit: &BlockEdit) -> Result<EditFeedback> {
+        for subscriber in self.find_edit_subscribers(&edit.block_id) {
+            let source = self.stream_sources.get(&subscriber.source_id)?;
+            let feedback = source.handle_block_edit(
+                &edit.block_id,
+                &edit.field,
+                edit.old_value.clone(),
+                edit.new_value.clone(),
+            ).await?;
+
+            match &feedback {
+                EditFeedback::Rejected { reason } => {
+                    // Send message to agent
+                    self.send_error_message(edit.agent_id, reason).await?;
+                }
+                EditFeedback::Applied { message } | EditFeedback::Pending { message } => {
+                    // Log to activity stream
+                    if let Some(msg) = message {
+                        self.log_activity(edit.agent_id, msg).await?;
+                    }
+                }
+            }
+
+            return Ok(feedback);
+        }
+
+        // No subscriber - direct edit allowed
+        Ok(EditFeedback::Applied { message: None })
+    }
+}
+```
+
+---
+
+## Example Implementations
+
+### File Source (DataBlock)
+
+```rust
+pub struct FileSource {
+    base_path: PathBuf,
+    permission_rules: Vec<PermissionRule>,
+    watch_enabled: bool,
+}
+
+impl DataBlock for FileSource {
+    fn schema(&self) -> BlockSchema {
+        BlockSchema::Text  // Files are text blocks
+    }
+
+    fn memory_type(&self) -> MemoryType {
+        MemoryType::Working
+    }
+
+    async fn load(&self, path: &str) -> Result<LoroDoc> {
+        let full_path = self.base_path.join(path);
+        let content = tokio::fs::read_to_string(&full_path).await?;
+
+        let doc = LoroDoc::new();
+        doc.get_text("content").insert(0, &content)?;
+        Ok(doc)
+    }
+
+    async fn save(&self, path: &str, doc: &LoroDoc) -> Result<()> {
+        let permission = self.permission_for(path);
+        permission.check(MemoryOp::Overwrite)?;
+
+        let content = doc.get_text("content").to_string();
+        let full_path = self.base_path.join(path);
+        tokio::fs::write(&full_path, content).await?;
+        Ok(())
+    }
+
+    fn required_tools(&self) -> Vec<ToolRegistration> {
+        vec![
+            // Consolidated tools with allowed operations
+            file_tool(ops: [Read, Append, Insert, Save]),
+            file_history_tool(ops: [View, Diff]),
+            file_search_tool(),
+        ]
+    }
+}
+```
+
+### LSP Source (DataStream - Passive)
+
+```rust
+pub struct LspSource {
+    language_server: Arc<LanguageServer>,
+}
+
+impl DataStream for LspSource {
+    fn pinned_block_schemas(&self) -> Vec<PinnedBlockSpec> {
+        vec![PinnedBlockSpec {
+            label: "lsp_diagnostics".into(),
+            schema: BlockSchema::Map {
+                fields: vec![
+                    FieldDef {
+                        name: "diagnostics".into(),
+                        field_type: FieldType::List,
+                        read_only: true,  // Source updates

+

+
+## Migration Path
+
+### Phase 1: Trait Definition
+- Define `DataBlock` and `DataStream` traits
+- Add schema-level `read_only` field flag
+- Update `BlockSchema` with new field metadata
+
+### Phase 2: File Source
+- Implement `FileSource` as `DataBlock`
+- Loro overlay with disk sync
+- Glob-based permission rules
+- Basic tools: read, append, history
+
+### Phase 3: Stream Sources
+- Migrate Bluesky to `DataStream` trait
+- Implement pinned config block
+- Implement ephemeral user profile blocks
+- Wire up block edit handling
+
+### Phase 4: Coordinator
+- Update coordinator to manage both source types
+- Implement block edit routing
+- Implement dynamic tool registration
+
+### Phase 5: Tools
+- Implement new tool taxonomy
+- Simplify recall tool
+- Add source control tools (pause/resume)
+
+---
+
+## Future Considerations
+
+### Plugin Model
+Eventually support WASM plugins for custom sources. Plugins would:
+- Declare their trait implementation (DataBlock or DataStream)
+- Provide schemas
+- Handle events and edits
+
+### MCP Integration
+Could present MCP tool resources as DataStream sources:
+- MCP resources become pinned blocks
+- Tool calls become block edits
+- Responses update blocks
+
+### Multi-Agent Block Collaboration
+With Loro CRDT foundation, could support:
+- Multiple agents editing same block
+- Conflict-free merging
+- Change attribution per agent
+
+---
+
+## Open Questions
+
+1. **Snapshot consolidation strategy** - When to consolidate Loro updates? Time-based, change-count, or size-based?
+
+2. **Block size limits** - How large can a file block get before we need chunking?
+
+3. **Watch debouncing** - For file watching, what's the right debounce window?
+
+4. **Tool capability verification** - How do we know an agent can handle patch operations before enabling the tool?

+# Data Source v2 Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Implement the new DataStream and DataBlock traits with source management integrated into RuntimeContext, enabling event-driven and document-oriented data sources with Loro-backed versioning.
+
+**Architecture:**
+- Two trait families: `DataStream` (events) and `DataBlock` (documents)
+- Source management lives on `RuntimeContext` (no separate coordinator)
+- `SourceManager` trait exposes source operations, `RuntimeContext` implements it
+- `ToolContext` gains `sources() -> &dyn SourceManager` for tool/source access
+- `AgentRuntime` holds `Weak<RuntimeContext>` to delegate source operations
+- Sources receive `Arc<dyn ToolContext>` just like tools—full access to memory, model, router, sources
+
+**Tech Stack:** Rust, tokio broadcast channels, Loro CRDT (existing), serde_json for flexible payloads, globset for path matching.
+
+**Scope Boundaries:**
+- ✅ In scope: Traits, types, SourceManager, RuntimeContext integration, helper utilities
+- ⚠️ Possibly separate: Full tool implementations (block, block_edit, source, recall)
+- ❌ Out of scope: Specific source implementations (Bluesky, LSP, File), shell hook integration
+
+---
+
+## Task 1: Core Types Module
+
+**Files:**
+- Create: `crates/pattern_core/src/data_source/types.rs`
+- Modify: `crates/pattern_core/src/data_source/mod.rs` (replace v1 with new types)
+
+**Step 1: Stub out old code, create new module structure**
+
+First, rename any existing files that will break:
+```bash
+# Stub out old implementations by renaming
+mv crates/pattern_core/src/data_source/traits.rs crates/pattern_core/src/data_source/traits.rs.old
+mv crates/pattern_core/src/data_source/coordinator.rs crates/pattern_core/src/data_source/coordinator.rs.old
+# etc. for any files that won't compile with new structure
+```
+
+Then update the module:
+```rust
+// crates/pattern_core/src/data_source/mod.rs
+//! Data Sources - Event-driven (DataStream) and Document-oriented (DataBlock) sources.
+//!
+//! Key design points:
+//! - No generics on traits (type safety at source boundary)
+//! - Sources receive `Arc<dyn ToolContext>` - same access as tools
+//! - Channel-based notifications with BlockRef references
+//! - Loro-backed versioning for DataBlock sources
+//! - Source management lives on RuntimeContext
+

+Append to `block.rs`:
+
+```rust
+/// Document-oriented data source with Loro-backed versioning.
+///
+/// Presents files and persistent documents as memory blocks with gated edits,
+/// version history, and rollback capabilities. Agent works with these like
+/// documents, pulling content when needed.
+///
+/// # Sync Model
+///
+/// ```text
+/// Agent tools ←→ Loro ←→ Disk ←→ Editor (ACP)
+///                  ↑
+///             Shell side effects
+/// ```
+///
+/// - **Loro as working state**: Agent's view with full version history
+/// - **Disk as canonical**: External changes win via reconcile
+/// - **Permission-gated writes**: Glob patterns determine access levels
+///

+## Task 6: Extend ToolContext with sources()
+
+**Files:**

+## Task 7: Add Weak<RuntimeContext> to AgentRuntime
+
+**Files:**
+- Modify: `crates/pattern_core/src/runtime/mod.rs` (AgentRuntime struct)
+- Modify: `crates/pattern_core/src/runtime/builder.rs` (if separate)
+
+**Step 1: Add runtime_context field to AgentRuntime**
+
+```rust
+use std::sync::Weak;
+
+pub struct AgentRuntime {
+    // ... existing fields ...
+
+    /// Weak reference to RuntimeContext for constellation-level operations
+    /// Used for source management, cross-agent communication, etc.
+    runtime_context: Option<Weak<RuntimeContext>>,
+}
+```
+
+**Step 2: Add builder method**
+
+```rust
+impl AgentRuntimeBuilder {
+    /// Set the runtime context (weak reference to avoid cycles)
+    pub fn runtime_context(mut self, ctx: Weak<RuntimeContext>) -> Self {
+        self.runtime_context = Some(ctx);
+        self
+    }
+}
+```
+
+**Step 3: Implement sources() for AgentRuntime**
+
+```rust
+impl ToolContext for AgentRuntime {
+    // ... existing implementations ...
+
+    fn sources(&self) -> Option<&dyn SourceManager> {
+        self.runtime_context
+            .as_ref()

+            // Problem: can't return reference to temporary Arc
+    }
+}
+```
+
+**Note:** The lifetime issue here requires a different approach. Options:
+1. Store `Arc<RuntimeContext>` (creates cycle, need care)
+2. Return `Option<Arc<dyn SourceManager>>` instead of reference
+3. Use interior caching pattern
+
+**Step 3 (revised): Change return type to Arc**
+
+```rust
+// In tool_context.rs, change the method signature:
+fn sources(&self) -> Option<Arc<dyn SourceManager>>;
+
+// In AgentRuntime implementation:
+fn sources(&self) -> Option<Arc<dyn SourceManager>> {
+    self.runtime_context
+        .as_ref()
+        .and_then(|weak| weak.upgrade())
+        .map(|arc| arc as Arc<dyn SourceManager>)
+}
+```
+
+**Step 4: Run check**
+
+Run: `cargo check -p pattern_core`
+Expected: PASS (after RuntimeContext implements SourceManager)
+
+**Step 5: Commit**
+
+```bash
+git add crates/pattern_core/src/runtime/

+## Task 14: Documentation
+
+**Files:**
+- Modify: `crates/pattern_core/src/data_source/mod.rs`
+
+**Step 1: Add module documentation**
+
+Expand the module doc at the top:
+
+```rust
+//! # Data Sources - Event and Document Sources
+//!
+//! This module provides the data source architecture with two trait families:
+//!
+//! ## DataStream - Event-Driven Sources
+//!
+//! For sources that produce notifications and/or maintain state blocks:
+//! - Bluesky firehose, Discord events, LSP diagnostics, sensors
+//! - Sources receive `Arc<dyn ToolContext>` - same access as tools
+//! - Channel-based notifications with `BlockRef` references
+//!
+//! ```ignore
+//! impl DataStream for MySource {
+//!     async fn start(&mut self, ctx: Arc<dyn ToolContext>, owner: AgentId)
+//!         -> Result<broadcast::Receiver<Notification>>
+//!     {
+//!         // Access memory, model, router, sources via ctx
+//!         // Create blocks, spawn processing task, return receiver
+//!     }
+//! }
+//! ```
+//!
+//! ## DataBlock - Document-Oriented Sources
+//!
+//! For persistent documents with versioning and permission-gated edits:
+//! - Files, configs, structured documents
+//! - Loro-backed with full version history and rollback
+//! - Disk as canonical with reconciliation after external changes
+//!
+//! ```ignore
+//! impl DataBlock for FileSource {
+//!     async fn load(&self, path: &str, ctx: &dyn ToolContext, owner: AgentId)
+//!         -> Result<BlockRef>
+//!     {
+//!         // Access memory via ctx.memory(), read file, create block
+//!     }
+//! }
+//! ```
+//!
+//! ## Source Management
+//!
+//! `RuntimeContext` implements `SourceManager` for source lifecycle:
+//! - Registration and lifecycle
+//! - Subscription management per agent
+//! - Block edit routing to interested sources
+//! - Access via `ToolContext::sources()`
+//!
+//! ## Helpers
+//!
+//! Utilities for implementing sources:
+//! - `BlockBuilder` - Fluent block creation
+//! - `NotificationBuilder` - Fluent notification creation
+//! - `EphemeralBlockCache` - Get-or-create for ephemeral blocks
+```
+
+**Step 2: Run doc check**
+
+Run: `cargo doc -p pattern_core --no-deps`
+Expected: PASS with no warnings
+
+**Step 3: Commit**

+Add to lib.rs exports:
+```rust
+// In the data_source section
+pub use data_source::{
+    DataStream, DataBlock,
+    BlockRef, Notification, StreamCursor, BlockSchemaSpec,
+    PermissionRule, FileChange, FileChangeType, VersionInfo,
+    ConflictResolution, ReconcileResult,
+    BlockBuilder, NotificationBuilder, EphemeralBlockCache,
+    ToolRule as DataSourceToolRule,  // Avoid conflict with existing ToolRule
+    SourceManager, StreamSourceInfo, BlockSourceInfo,
+    BlockEdit, EditFeedback,
+};
+```
+
+**Step 2: Run check**
+
+Run: `cargo check -p pattern_core`
+Expected: PASS
+
+**Step 3: Commit**
+
+```bash
+git add crates/pattern_core/src/lib.rs
+git commit -m "feat(pattern_core): export data source types
+
+Public API for DataStream, DataBlock, SourceManager, and helpers."
+```
+

+
+## Task 16: Tool Stubs (Optional - May Warrant Separate Plan)
+
+**Files:**
+- Create: `crates/pattern_core/src/tool/builtin/block_tool.rs`
+- Create: `crates/pattern_core/src/tool/builtin/source_tool.rs`
+
+**Decision Point:** The tool implementations (block, block_edit, source, recall) are substantial. This task creates minimal stubs. Full implementation should be a separate plan.
+
+**Step 1: Create block tool stub**
+
+```rust
+// crates/pattern_core/src/tool/builtin/block_tool.rs
+//! Block lifecycle management tool
+//!
+//! Operations: load, pin, unpin, archive, info
+//!
+//! TODO: Full implementation in separate plan
+
+use serde::{Deserialize, Serialize};
+use schemars::JsonSchema;
+
+#[derive(Debug, Clone, Serialize, Deserialize, JsonSchema)]
+pub enum BlockOperation {
+    Load,
+    Pin,
+    Unpin,
+    Archive,
+    Info,
+}
+
+#[derive(Debug, Clone, Serialize, Deserialize, JsonSchema)]
+pub struct BlockToolInput {
+    pub label: String,
+    pub operation: BlockOperation,
+}
+
+#[derive(Debug, Clone, Serialize, Deserialize, JsonSchema)]
+pub struct BlockToolOutput {
+    pub success: bool,
+    pub message: Option<String>,
+    pub data: Option<serde_json::Value>,
+}
+
+// TODO: Implement AiTool trait
+```
+
+**Step 2: Create source tool stub**
+
+```rust
+// crates/pattern_core/src/tool/builtin/source_tool.rs
+//! Data source control tool
+//!
+//! Operations: pause, resume, status
+//!
+//! TODO: Full implementation in separate plan
+
+use serde::{Deserialize, Serialize};
+use schemars::JsonSchema;
+
+#[derive(Debug, Clone, Serialize, Deserialize, JsonSchema)]
+pub enum SourceOperation {
+    Pause,
+    Resume,
+    Status,
+}
+
+#[derive(Debug, Clone, Serialize, Deserialize, JsonSchema)]
+pub struct SourceToolInput {
+    pub source_id: String,
+    pub operation: SourceOperation,
+}
+
+#[derive(Debug, Clone, Serialize, Deserialize, JsonSchema)]
+pub struct SourceToolOutput {
+    pub success: bool,
+    pub message: Option<String>,
+    pub status: Option<String>,
+}
+
+// TODO: Implement AiTool trait
+```
+
+**Step 3: Commit**
+
+```bash
+git add crates/pattern_core/src/tool/builtin/block_tool.rs
+git add crates/pattern_core/src/tool/builtin/source_tool.rs
+git commit -m "feat(tools): add block and source tool stubs
+
+Minimal type definitions for block lifecycle and source control tools.
+Full implementation deferred to separate plan."
+```
+
+---
+
+## Summary
+
+This plan implements the core data source infrastructure:
+
+1. **Tasks 1-4**: Core types and trait definitions (DataStream, DataBlock)
+2. **Tasks 5-7**: SourceManager trait and ToolContext integration
+3. **Tasks 8-9**: RuntimeContext source storage and SourceManager implementation
+4. **Tasks 10-11**: Helper utilities and MemoryStore extension
+5. **Task 12**: Context builder integration
+6. **Tasks 13-15**: Tests, documentation, exports
+7. **Task 16**: Optional tool stubs
+
+**Key architectural decisions:**
+- Source management lives on RuntimeContext (no separate coordinator)
+- ToolContext gains `sources() -> Arc<dyn SourceManager>`
+- AgentRuntime holds `Weak<RuntimeContext>` to implement sources()
+- Sources receive `Arc<dyn ToolContext>` - same access as tools
+
+**Not in scope** (require separate plans):
+- Full tool implementations (block, block_edit, source, recall)
+- Specific source implementations (Bluesky, LSP, File)
+- Shell hook integration for permission enforcement
+- Conflict resolution UI for Human permission escalation
+
+**Estimated commits**: 14-15 focused commits
+**Dependencies**: Existing pattern_core memory and tool infrastructure
+
+## Post-Implementation TODOs
+
+- Add deregistration methods to RuntimeContext (unregister_stream, unregister_block_source)
+- Consider adding unregistration to ToolRegistry as well for parity

+# DataBlock Trait Design
+
+## Purpose
+
+Present files and persistent documents as Loro-backed memory blocks with gated edits, version history, and rollback capabilities. Agent works with these like documents, pulling content when needed.
+
+## Design Principles
+
+**No generics on the trait** - Same as DataStream, type safety at source boundary.
+
+**Loro as working state** - Agent's view of the file, with full version history and rollback.
+
+**Disk as canonical** - External changes (shell, editor, other processes) win. Watch detects changes and updates Loro overlay.
+
+**Permission-gated writes** - Glob-based rules determine what agent can do with each path.
+
+## Sync Model
+
+```
+Agent tools ←→ Loro ←→ Disk ←→ Editor (ACP)
+                 ↑
+            Shell side effects
+```
+
+Multiple writers:
+- **Agent edits** via tools → Loro → disk (permission-gated)
+- **Shell commands** → disk → reconcile to Loro
+- **Editor (ACP)** → disk or direct → reconcile to Loro
+- **External processes** → disk → watch triggers Loro update
+
+Loro overlay can be ahead of disk (uncommitted changes) or behind (external changes detected).
+
+## Types
+
+```rust
+pub struct PermissionRule {
+    pub pattern: String,  // Glob pattern: "*.config.toml", "src/**/*.rs"
+    pub permission: MemoryPermission,
+    pub operations_requiring_escalation: Vec<String>,  // e.g., ["delete", "overwrite"]
+}
+
+pub struct FileChange {
+    pub path: String,
+    pub change_type: FileChangeType,
+    pub block_id: Option<String>,  // If we have a loaded block for this path
+}
+
+pub enum FileChangeType {
+    Modified,
+    Created,
+    Deleted,
+}
+
+/// Spec for documentation
+pub struct DataBlockSpec {
+    pub base_path: String,
+    pub permission_rules: Vec<PermissionRule>,
+    pub watch_enabled: bool,
+    pub description: String,
+}
+```
+
+## Trait Definition
+
+```rust

+
+pub struct VersionInfo {
+    pub version_id: String,
+    pub timestamp: DateTime<Utc>,
+    pub description: Option<String>,
+}
+```
+
+## Watch Semantics
+
+### Scope
+
+- **Single file path** → watch that file only
+- **Directory path** → watch recursively, including subdirs
+- **Respect ignore files** → `.gitignore`, `.loroignore`, or similar to exclude paths
+
+### Debouncing
+
+Loro has built-in change merging via `set_change_merge_interval()`. For file watching:
+- Use filesystem watcher's debounce (e.g., `notify` crate's debounced watcher)
+- Recommended: 100-500ms debounce window for typical editing
+- Loro's internal merge interval can be shorter for responsive collaboration
+
+### Conflict Handling via Fork-and-Compare
+
+Rather than blindly merging, we fork the doc to compare both sides independently:
+
+```rust
+async fn reconcile(&self, path: &str, memory: &dyn MemoryStore) -> Result<ReconcileResult> {
+    let block = memory.get_block(&owner, &label).await?;
+    let loro_doc = block.loro_doc();
+
+    // Get the last known synced state (common ancestor)
+    let last_synced = self.get_last_synced_frontiers(path)?;
+
+    // Fork 1: Apply disk state
+    let disk_fork = loro_doc.fork_at(&last_synced)?;
+    let disk_content = fs::read_to_string(path).await?;
+    {
+        let text = disk_fork.get_text("content");
+        text.delete(0, text.len_unicode())?;
+        text.insert(0, &disk_content)?;
+        disk_fork.commit();
+    }
+
+    // Fork 2: Current agent state (already in loro_doc)
+    let agent_fork = loro_doc.fork_at(&last_synced)?;
+    agent_fork.import(&loro_doc.export(ExportMode::updates(&last_synced)))?;
+
+    // Diff both forks against common ancestor
+    let disk_changes = disk_fork.diff(&last_synced, &disk_fork.state_frontiers());
+    let agent_changes = agent_fork.diff(&last_synced, &agent_fork.state_frontiers());
+
+    // Decide which wins based on source rules
+    let resolution = self.resolve_conflict(path, &disk_changes, &agent_changes)?;
+
+    match resolution {
+        ConflictResolution::DiskWins => {
+            // Replace agent state with disk state
+            loro_doc.checkout(&last_synced)?;

+        ConflictResolution::AgentWins => {
+            // Keep agent state, ignore disk changes

+            // Import both - CRDT merges, most recent ops win ties
+            loro_doc.import(&disk_fork.export(ExportMode::all_updates()))?;
+        }
+        ConflictResolution::Conflict { disk_diff, agent_diff } => {
+            // Can't auto-resolve - surface to agent for decision
+            return Ok(ReconcileResult::NeedsResolution {

+                disk_changes: disk_diff,
+                agent_changes: agent_diff,
+            });
+        }
+    }
+
+    // Update last synced frontier
+    self.set_last_synced_frontiers(path, loro_doc.state_frontiers())?;

+            Ok(ConflictResolution::DiskWins)
+        }

+}
+
+pub enum ConflictResolution {
+    DiskWins,
+    AgentWins,
+    Merge,
+    Conflict { disk_diff: Diff, agent_diff: Diff },
+}
+
+pub enum ReconcileResult {
+    Resolved {

+```
+
+**Resolution rules by permission:**
+
+| Permission | Both Sides Changed | Behavior |
+|------------|-------------------|----------|
+| ReadOnly | Disk wins | Agent edits discarded (shouldn't have happened) |
+| Human | Surface conflict | Agent must explicitly choose |
+| ReadWrite | Merge (agent priority) | CRDT merge, agent ops win ties |
+
+### Watching Implementation
+
+```rust
+pub struct FileWatcher {
+    watcher: RecommendedWatcher,
+    tx: broadcast::Sender<FileChange>,
+    ignore_patterns: Vec<GlobPattern>,
+}
+
+impl FileWatcher {
+    pub fn new(base_path: &Path, ignore_file: Option<&Path>) -> Result<Self> {
+        let (tx, _) = broadcast::channel(256);
+
+        // Load ignore patterns
+        let ignore_patterns = ignore_file
+            .and_then(|p| fs::read_to_string(p).ok())
+            .map(|content| parse_gitignore(&content))
+            .unwrap_or_default();
+
+        // Create debounced watcher
+        let watcher = notify::recommended_watcher(move |res: Result<Event, _>| {
+            if let Ok(event) = res {
+                // Filter by ignore patterns
+                for path in event.paths {
+                    if !should_ignore(&path, &ignore_patterns) {
+                        let change = FileChange {
+                            path: path.to_string_lossy().to_string(),
+                            change_type: event.kind.into(),
+                            block_id: None,  // Filled in by reconcile
+                        };
+                        let _ = tx.send(change);
+                    }
+                }
+            }
+        })?;
+
+        Ok(Self { watcher, tx, ignore_patterns })
+    }
+
+    pub fn watch(&mut self, path: &Path) -> Result<()> {
+        self.watcher.watch(path, RecursiveMode::Recursive)?;
+        Ok(())
+    }
+
+    pub fn subscribe(&self) -> broadcast::Receiver<FileChange> {
+        self.tx.subscribe()
+    }
+}
+```
+
+### Watch Event Flow
+
+1. Filesystem change detected by `notify` watcher
+2. Debounce window elapses
+3. `FileChange` emitted on broadcast channel
+4. Coordinator receives, checks if path has loaded block
+5. If loaded: call `reconcile()` to merge disk state into Loro
+6. If significant changes: optionally notify agent via activity log
+
+### Detached Mode for Staging
+
+For complex operations, can use Loro's detached mode:
+
+```rust
+// Stage changes without applying
+loro_doc.detach();
+
+// Import external changes to oplog only
+loro_doc.import(&update)?;
+
+// Preview diff before applying
+let diff = loro_doc.diff(&loro_doc.state_frontiers(), &loro_doc.oplog_frontiers());
+
+// Apply when ready
+loro_doc.checkout_to_latest();
+// or revert:
+// loro_doc.attach();  // Discard staged changes
+```
+
+This allows agent to review external changes before accepting them.
+
+## Shell Tool Integration
+
+The shell/bash tool needs pre/post hooks to:
+1. **Enforce permissions** - prevent operations outside permitted boundaries
+2. **Capture changes** - reconcile Loro state with what shell did
+3. **Report violations** - log/warn if command exceeded permissions
+
+### Pre-Execution Hook
+
+Before running a shell command:
+
+```rust
+pub struct ShellPreHook {
+    file_source: Arc<dyn DataBlock>,
+    permission_rules: Vec<PermissionRule>,
+}
+
+impl ShellPreHook {
+    /// Analyze command and check if it would violate permissions
+    pub fn check(&self, command: &str, working_dir: &Path) -> PreHookResult {
+        // Best-effort static analysis of command
+        let predicted_paths = analyze_command_paths(command, working_dir);
+
+        let mut violations = Vec::new();
+        let mut warnings = Vec::new();
+
+        for path in &predicted_paths {
+            let permission = self.file_source.permission_for(path);
+            let op = predict_operation(command, path);  // read, write, delete, etc.
+
+            match (permission, op) {
+                (MemoryPermission::ReadOnly, Operation::Write | Operation::Delete) => {
+                    violations.push(PermissionViolation {
+                        path: path.clone(),
+                        attempted: op,
+                        allowed: permission,
+                    });
+                }
+                (MemoryPermission::Human, op) if op.is_destructive() => {
+                    warnings.push(EscalationRequired {
+                        path: path.clone(),
+                        operation: op,
+                        reason: "Requires human approval".into(),
+                    });
+                }
+                _ => {}
+            }
+        }
+
+        // Also check for unpredictable commands
+        if is_unpredictable(command) {
+            warnings.push(Warning::UnpredictableCommand(command.to_string()));
+        }
+
+        PreHookResult { violations, warnings, predicted_paths }
+    }
+}
+
+pub enum PreHookDecision {
+    Allow,
+    AllowWithWarning(Vec<Warning>),
+    Block(Vec<PermissionViolation>),
+    RequireEscalation(Vec<EscalationRequired>),
+}
+```
+
+**Command analysis heuristics:**
+- Parse common patterns: `rm`, `mv`, `cp`, `echo >`, `cat >`, `sed -i`, etc.
+- Extract path arguments
+- Resolve relative paths against working directory
+- Flag unpredictable commands: pipes to unknown programs, `eval`, `$(...)`, etc.
+
+### Post-Execution Hook
+
+After shell command completes:
+
+```rust
+pub struct ShellPostHook {
+    file_source: Arc<dyn DataBlock>,
+    memory: Arc<dyn MemoryStore>,
+}
+
+impl ShellPostHook {
+    /// Reconcile filesystem state and report what changed
+    pub async fn reconcile(
+        &self,
+        command: &str,
+        predicted_paths: &[String],
+        snapshot_before: &FilesystemSnapshot,

+
+### Permission Enforcement Levels
+
+| Level | Pre-Hook | Post-Hook | Use Case |
+|-------|----------|-----------|----------|
+| **Strict** | Block on predicted violation | Report violations | Production agents |
+| **Warned** | Warn but allow | Report violations | Development/testing |
+| **Audit** | Log only | Log only | Debugging, permissive agents |
+| **None** | Skip | Skip | Trusted environments |
+
+### Sandboxing (Future)
+
+For stronger isolation, could integrate:
+- **bubblewrap/firejail** - Linux sandboxing with path restrictions
+- **chroot** - Restrict filesystem view
+- **seccomp** - Syscall filtering
+
+These would provide enforcement beyond best-effort analysis, but add complexity and platform dependencies.
+
+## Editor Integration (ACP) - Future
+
+Agent Client Protocol integration points:
+- File open/close events → load/unload blocks
+- Editor saves → treated like disk change, reconcile
+- Editor buffer changes → could sync to Loro in real-time (collaborative editing)
+- Agent saves → push to editor buffer and/or disk

+
+## Questions
+
+1. **Conflict resolution** - What happens when agent has unsaved Loro edits and disk changes? Options:
+   - resolved above
+
+2. **Block labels** - Using `file:{path}` as label. Should path be relative or absolute? Relative to base_path seems cleaner.
+   - `file:{base_path_hash}:{relative_path}` seems good? doesn't expose the base path, but eliminates collisions/
+
+3. **Multi-agent access** - If two agents load same file, separate blocks or shared? 
+   - Think shared, for simplicity, but equally easy to just have two blocks and keep them synced via subscription

+# DataStream Trait Design
+
+## Purpose
+
+Handle event-driven sources that produce notifications and/or maintain state blocks. Sources are autonomous - they have direct memory store access and manage their own blocks.
+
+## Design Principles
+
+**No generics on the trait** - Type safety lives at the source implementation boundary (Jacquard gives typed ATProto, LSP client gives typed diagnostics). By the time events hit the DataStream interface, they've been validated and we need flexible routing.
+
+**Channel-based notifications** - Source emits `Notification` on a broadcast channel. Coordinator routes to subscribed agents. Natural backpressure, simple model.
+
+**Blocks persist, context is filtered** - "Ephemeral" means blocks drop out of context after batch processing, not that they're deleted. They persist in memory store and can be brought back by another notification or explicit agent action.
+
+## Block Lifecycle
+
+**Pinned blocks** (`pinned=true`):
+- Config blocks for the source
+- Passive state (LSP diagnostics, sensor readings)
+- Always loaded in agent context while subscribed
+- Agent can unpin to make ephemeral
+
+**Ephemeral blocks** (`pinned=false`):
+- Created with notification, referenced by block_id
+- Loaded for the batch that references them
+- Drop out of context after batch completes
+- Agent can `pin` to retain, or `load` for temporary peek
+
+## Block Loading Rules
+
+Context builder filters Working blocks:
+1. `pinned == true` → always loaded
+2. `block_id in batch_block_ids` → loaded for this batch
+3. Otherwise → not loaded (but still exists in store)
+
+Agent can use `block` tool:
+- `load` → adds to current batch, ContinueLoop gives another turn with it visible
+- `pin` → sets pinned=true, persistent in context
+- `unpin` → sets pinned=false, becomes ephemeral
+
+Tool execution results can include `keep_blocks: Vec<String>` that carries forward to next batch.
+
+## Types
+
+```rust
+/// Event from any streaming source (internal to source)
+pub struct StreamEvent {
+    pub event_type: String,
+    pub payload: serde_json::Value,  // Source-specific, validated at source
+    pub cursor: Option<String>,       // Opaque resume token
+    pub timestamp: DateTime<Utc>,

+/// Notification delivered to agent via broadcast channel
+pub struct Notification {
+    /// Full Message type - supports text, images, multi-modal content

+
+    /// Blocks to load for this batch (already exist in memory store)
+    pub block_refs: Vec<BlockRef>,
+
+    /// Batch to associate these blocks with
+    pub batch_id: SnowflakePosition,
+}
+
+/// Reference to a block in memory store
+pub struct BlockRef {
+    pub label: String,
+    pub block_id: String,
+    pub agent_id: String,  // Owner, defaults to "_constellation_"
+}
+
+impl BlockRef {
+    pub fn new(label: impl Into<String>, block_id: impl Into<String>) -> Self {
+        Self {
+            label: label.into(),
+            block_id: block_id.into(),
+            agent_id: "_constellation_".to_string(),
+        }
+    }
+
+    pub fn owned_by(mut self, agent_id: impl Into<String>) -> Self {
+        self.agent_id = agent_id.into();
+        self
+    }
+}
+
+/// Opaque cursor for pull-based access
+pub struct StreamCursor(pub String);
+
+/// Schema spec for documentation/validation
+pub struct BlockSchemaSpec {
+    pub label_pattern: String,  // "bluesky_user_{handle}" or exact "lsp_diagnostics"
+    pub schema: BlockSchema,
+    pub description: String,
+    pub pinned: bool,           // Created pinned (config) vs ephemeral (per-event)
+}
+```
+
+## Trait Definition
+
+```rust

+
+    // === Lifecycle ===
+
+    /// Start the source, returns broadcast receiver for notifications.
+    /// Source receives memory store access here and manages its own blocks.
+    async fn start(
+        &mut self,
+        memory: Arc<dyn MemoryStore>,

+        &self,
+        limit: usize,
+        cursor: Option<StreamCursor>,
+    ) -> Result<Vec<Notification>> {
+        Ok(vec![])
+    }
+}
+```
+
+## Context Builder Integration
+
+```rust
+impl<'a> ContextBuilder<'a> {
+    /// Set block IDs to keep loaded for this batch (even if unpinned)
+    pub fn with_batch_blocks(mut self, block_ids: Vec<String>) -> Self {
+        self.batch_block_ids = Some(block_ids);
+        self
+    }
+}
+
+// In build(), filter Working blocks:
+let working_blocks: Vec<BlockMetadata> = owned_working_blocks
+    .into_iter()
+    .filter(|b| {
+        b.pinned || self.batch_block_ids
+            .as_ref()
+            .map(|ids| ids.contains(&b.id))
+            .unwrap_or(false)
+    })
+    .collect();
+```
+
+## Example Flow
+
+1. BlueskySource receives post from Jetstream
+2. Source creates user profile block in memory store (pinned=false)
+3. Source sends `Notification { message: Message::user(...), block_refs: [BlockRef::new("bluesky_user_alice", block_id)], batch_id }`
+4. Coordinator receives, routes to subscribed agent
+5. Processing loop calls `ContextBuilder::with_batch_blocks([block_id]).with_active_batch(batch_id)`
+6. Agent sees the post message + user profile block in context
+7. Agent processes, maybe pins the block if user is interesting
+8. Batch completes - unpinned block drops out of context (still in store)
+9. Later notification can reference same block_id, or agent can `load` it explicitly
+
+## Example: Bluesky Source
+
+```rust
+pub struct BlueskySource {
+    jetstream: JetstreamClient,
+    memory: Option<Arc<dyn MemoryStore>>,

+
+The LSP source demonstrates the "passive" pattern - it maintains a pinned block that it updates periodically, but doesn't send notifications. The agent always sees current diagnostics in context without being interrupted.

+# Tool Operation Gating and Memory System Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Extend the tool rules system with operation-level gating and add field-level permissions with Loro subscription support to StructuredDocument.
+
+**Architecture:** Tool operations are schema-filtered before LLM sees them and runtime-validated on execution. Memory blocks gain field-level read_only flags, section parameters for Composite schemas, and Loro subscription passthrough for edit watching.
+
+**Tech Stack:** Rust, Loro CRDT, serde/schemars for JSON schema manipulation
+
+---
+
+## Overview
+
+Two major pieces of work:
+
+1. **Tool Operation Gating** (Tasks 1-7) - Filter multi-operation tools at schema level
+2. **Block Schema & Loro Integration** (Tasks 8-16) - Field permissions and subscriptions
+
+Dependencies:
+- Tasks 1-7 are independent of Tasks 8-16
+- Within each group, tasks must be sequential (each builds on previous)
+
+---
+
+## Task 1: Add AllowedOperations Variant to ToolRuleType
+
+**Files:**
+- Modify: `crates/pattern_core/src/tool/rules/engine.rs:30-72` (ToolRuleType enum)
+
+**Step 1: Write the failing test**
+
+Add to `crates/pattern_core/src/tool/rules/engine.rs` in the tests module:
+
+```rust
+#[test]
+fn test_allowed_operations_rule_type() {
+    use std::collections::HashSet;
+
+    let allowed: HashSet<String> = ["read", "append"].iter().map(|s| s.to_string()).collect();
+    let rule_type = ToolRuleType::AllowedOperations(allowed.clone());
+
+    let description = rule_type.to_usage_description("file", &[]);
+    assert!(description.contains("file"));
+    assert!(description.contains("read"));
+    assert!(description.contains("append"));
+}
+```
+
+**Step 2: Run test to verify it fails**
+
+Run: `cargo test -p pattern_core test_allowed_operations_rule_type`
+Expected: FAIL with "no variant named AllowedOperations"
+
+**Step 3: Add the AllowedOperations variant**
+
+In `ToolRuleType` enum (around line 70):
+
+```rust
+pub enum ToolRuleType {
+    // ... existing variants ...
+
+    /// Only allow these operations for multi-operation tools.
+    /// Operations not in this set are hidden from the schema and rejected at execution.
+    AllowedOperations(HashSet<String>),
+}
+```
+
+Add import at top of file:
+```rust
+use std::collections::HashSet;
+```
+
+**Step 4: Add to_usage_description match arm**
+
+In the `to_usage_description` method (around line 74-171), add:
+
+```rust
+ToolRuleType::AllowedOperations(ops) => {
+    let ops_list: Vec<_> = ops.iter().cloned().collect();
+    format!(
+        "available operations for `{}`: {}",
+        tool_name,
+        ops_list.join(", ")
+    )
+}
+```
+
+**Step 5: Run test to verify it passes**
+
+Run: `cargo test -p pattern_core test_allowed_operations_rule_type`
+Expected: PASS
+
+**Step 6: Commit**
+
+```bash
+git add crates/pattern_core/src/tool/rules/engine.rs
+git commit -m "feat(tool): add AllowedOperations variant to ToolRuleType"
+```

+## Task 2: Add Operations Methods to AiTool Trait
+
+**Files:**
+- Modify: `crates/pattern_core/src/tool/mod.rs:35-117` (AiTool trait)
+
+**Step 1: Write the failing test**
+
+Add to test module in `crates/pattern_core/src/tool/mod.rs`:

+
+Run: `cargo test -p pattern_core test_ai_tool_operations`
+Expected: FAIL with "method `operations` not found"
+
+**Step 3: Add operations methods to AiTool trait**
+
+In `AiTool` trait definition (around line 35-117), add these methods:
+
+```rust
+/// Operations this tool supports. Empty slice means not operation-based.
+/// Return static strings matching the operation enum variant names (snake_case).

+
+**Step 2: Run test to verify it fails**
+
+Run: `cargo test -p pattern_core test_composite_section_read_only`
+Expected: FAIL with "expected struct, found enum variant"
+
+**Step 3: Define CompositeSection struct and update Composite variant**
+
+Add struct:
+
+```rust
+#[derive(Debug, Clone, Serialize, Deserialize)]
+pub struct CompositeSection {
+    pub name: String,
+    pub schema: Box<BlockSchema>,
+    #[serde(default)]
+    pub description: Option<String>,
+    /// If true, only system/source code can write to this section.
+    #[serde(default)]
+    pub read_only: bool,
+}
+```
+
+Update `BlockSchema::Composite` variant:
+
+```rust
+pub enum BlockSchema {
+    // ... other variants ...
+
+    /// Multi-section document with different schemas per section
+    Composite {
+        sections: Vec<CompositeSection>,
+    },
+}
+```
+
+Add helper method:
+
+```rust
+impl BlockSchema {
+    // ... existing methods ...
+
+    /// Check if a section is read-only (for Composite schemas).
+    pub fn is_section_read_only(&self, section_name: &str) -> Option<bool> {

+}
+```
+
+**Step 4: Update existing Composite usages**
+
+Search for `BlockSchema::Composite` and update to use new structure. Old format was likely `Vec<(String, BlockSchema)>`.

+- `set_field`
+- `set_text_field`
+- `append_to_list_field`
+- `remove_from_list_field`
+- `increment_counter`
+
+**Step 1: Write the failing test**

+
+**Step 4: Update remaining write methods similarly**
+
+- `set_text_field(name, value, is_system)`
+- `append_to_list_field(name, value, is_system)`
+- `remove_from_list_field(name, index, is_system)`
+- `increment_counter(name, delta, is_system)`
+
+**Step 5: Update all call sites**
+
+Search for each method call and add the appropriate `is_system` parameter:
+- Tool code: `false`
+- System/source code: `true`
+- Tests: typically `true` or `false` depending on what's being tested

+# Tool Operation Gating Design
+
+## Overview
+
+This design extends the existing tool rules system to support **operation-level gating** for multi-operation tools. Rather than all-or-nothing tool access, agents can be restricted to specific operations within a tool (e.g., `file` tool with only `read` and `append`, not `patch`).
+
+The key insight: **the schema shown to the LLM should only include operations the agent is allowed to use**.
+
+## Goals
+
+1. **Generic**: Works with any multi-operation tool without special-casing
+2. **Type-safe**: Invalid operation names caught at config load or registration
+3. **Non-breaking**: Existing tools work unchanged (default = all operations)
+4. **Schema-aware**: Filtered operations don't appear in the LLM's tool schema
+
+## Design
+
+### 1. New ToolRuleType Variant
+
+Add to `crates/pattern_core/src/tool/rules/engine.rs`:
+
+```rust
+pub enum ToolRuleType {
+    // ... existing variants ...
+
+    /// Only allow these operations for multi-operation tools.
+    /// Operations not in this set are hidden from the schema and rejected at execution.
+    AllowedOperations(HashSet<String>),
+}
+
+impl ToolRuleType {
+    pub fn to_usage_description(&self, tool_name: &str, conditions: &[String]) -> String {
+        match self {
+            // ... existing matches ...
+
+            ToolRuleType::AllowedOperations(ops) => {
+                format!(
+                    "`{}` is limited to these operations: {}",
+                    tool_name,
+                    ops.iter().cloned().collect::<Vec<_>>().join(", ")
+                )
+            }
+        }
+    }
+}
+```
+
+### 2. AiTool Trait Extensions
+
+Add to `crates/pattern_core/src/tool/mod.rs`:
+
+```rust
+pub trait AiTool: Send + Sync + Debug {
+    // ... existing methods ...
+
+    /// Operations this tool supports. Empty slice means not operation-based.
+    /// Should return static strings matching the operation enum variant names.
+    fn operations(&self) -> &'static [&'static str] {
+        &[]
+    }
+
+    /// Generate schema filtered to only allowed operations.
+    /// Default implementation returns full schema (no filtering).
+    fn parameters_schema_filtered(&self, allowed_ops: &HashSet<String>) -> Value {
+        let _ = allowed_ops; // unused in default impl
+        self.parameters_schema()
+    }
+}
+```
+
+### 3. DynamicTool Trait Extensions
+
+The type-erased `DynamicTool` trait (what's actually stored in the registry) needs corresponding methods. Add to trait definition:
+
+```rust
+#[async_trait]
+pub trait DynamicTool: Send + Sync + Debug {
+    // ... existing methods (clone_box, name, description, parameters_schema,
+    //     output_schema, execute, validate_params, examples, usage_rule,
+    //     tool_rules, to_genai_tool) ...
+
+    /// Operations this tool supports. Empty slice means not operation-based.
+    fn operations(&self) -> &'static [&'static str] {
+        &[]
+    }
+
+    /// Generate schema filtered to only allowed operations.
+    fn parameters_schema_filtered(&self, allowed_ops: &HashSet<String>) -> Value {
+        let _ = allowed_ops;
+        self.parameters_schema()
+    }
+
+    /// Convert to genai Tool with operation filtering applied
+    fn to_genai_tool_filtered(&self, allowed_ops: Option<&HashSet<String>>) -> genai::chat::Tool {
+        let schema = match allowed_ops {
+            Some(ops) => self.parameters_schema_filtered(ops),
+            None => self.parameters_schema(),
+        };
+        genai::chat::Tool::new(self.name())
+            .with_description(self.description())
+            .with_schema(schema)
+    }
+}
+```
+
+Update `DynamicToolAdapter<T>` implementation to delegate to inner tool:
+
+```rust
+#[async_trait]
+impl<T> DynamicTool for DynamicToolAdapter<T>
+where
+    T: AiTool + Clone + 'static,
+{
+    // ... existing method impls ...
+
+    fn operations(&self) -> &'static [&'static str] {
+        self.inner.operations()
+    }
+
+    fn parameters_schema_filtered(&self, allowed_ops: &HashSet<String>) -> Value {
+        self.inner.parameters_schema_filtered(allowed_ops)
+    }
+}
+```
+
+### 4. ToolRegistry Changes
+
+Add method to generate tools with rule-based filtering:
+
+```rust
+impl ToolRegistry {
+    /// Get all tools as genai tools, applying operation gating from rules
+    pub fn to_genai_tools_with_rules(&self, rules: &[ToolRule]) -> Vec<genai::chat::Tool> {
+        self.tools
+            .iter()
+            .map(|entry| {
+                let tool = entry.value();
+                let tool_name = tool.name();
+
+                // Find AllowedOperations rule for this tool
+                let allowed_ops = self.find_allowed_operations(tool_name, rules);
+
+                // Validate configured operations if present
+                if let Some(ref ops) = allowed_ops {
+                    self.validate_operations(tool_name, tool.operations(), ops);
+                }
+
+                // Use the filtered conversion method on DynamicTool
+                tool.to_genai_tool_filtered(allowed_ops.as_ref())
+            })
+            .collect()
+    }
+
+    /// Find AllowedOperations rule for a tool
+    fn find_allowed_operations(&self, tool_name: &str, rules: &[ToolRule]) -> Option<HashSet<String>> {
+        rules.iter()
+            .find(|r| r.tool_name == tool_name || r.tool_name == "*")
+            .and_then(|r| match &r.rule_type {
+                ToolRuleType::AllowedOperations(ops) => Some(ops.clone()),
+                _ => None,
+            })
+    }
+
+    /// Validate that configured operations exist on the tool
+    fn validate_operations(
+        &self,
+        tool_name: &str,
+        declared: &'static [&'static str],
+        configured: &HashSet<String>,
+    ) {
+        if declared.is_empty() {
+            // Tool doesn't declare operations - can't validate
+            tracing::warn!(
+                tool = tool_name,
+                "AllowedOperations rule applied to tool that doesn't declare operations"
+            );
+            return;
+        }
+
+        let declared_set: HashSet<&str> = declared.iter().copied().collect();
+        for op in configured {
+            if !declared_set.contains(op.as_str()) {
+                tracing::warn!(
+                    tool = tool_name,
+                    operation = op,
+                    available = ?declared,
+                    "Configured operation not found in tool's declared operations"
+                );
+            }
+        }
+    }
+}
+```
+
+### 5. ContextBuilder Integration
+
+Update `crates/pattern_core/src/context/builder.rs`:
+
+```rust
+impl ContextBuilder<'_> {
+    pub async fn build(self) -> Result<Request, ContextError> {
+        // ... existing code ...
+
+        // Get tools in genai format with operation gating applied
+        let tools = self.tools.map(|registry| {
+            registry.to_genai_tools_with_rules(&self.tool_rules)
+        });
+
+        // ... rest of build ...
+    }
+}
+```
+
+### 6. Schema Filtering Helper
+
+Utility for filtering enum fields in JSON schemas:
+
+```rust
+// In crates/pattern_core/src/tool/mod.rs or a new utils module
+
+/// Filter an enum field in a JSON schema to only include allowed values
+pub fn filter_schema_enum(
+    schema: &mut Value,
+    field_name: &str,
+    allowed_values: &HashSet<String>,
+) {
+    // Navigate to the field's schema
+    if let Some(properties) = schema.get_mut("properties") {
+        if let Some(field) = properties.get_mut(field_name) {
+            // Handle direct enum
+            if let Some(enum_values) = field.get_mut("enum") {
+                if let Some(arr) = enum_values.as_array_mut() {
+                    arr.retain(|v| {
+                        v.as_str().map(|s| allowed_values.contains(s)).unwrap_or(false)
+                    });
+                }
+            }
+
+            // Handle oneOf pattern (for tagged enums with descriptions)
+            if let Some(one_of) = field.get_mut("oneOf") {
+                if let Some(arr) = one_of.as_array_mut() {
+                    arr.retain(|variant| {
+                        variant.get("const")
+                            .and_then(|v| v.as_str())
+                            .map(|s| allowed_values.contains(s))
+                            .unwrap_or(false)
+                    });
+                }
+            }
+        }
+    }
+}
+```
+
+## Example: File Tool Implementation
+
+```rust
+#[derive(Debug, Clone, Serialize, Deserialize, JsonSchema)]
+#[serde(rename_all = "snake_case")]
+pub enum FileOperation {
+    Read,
+    Append,
+    Insert,
+    Patch,
+    Save,
+}
+
+#[derive(Debug, Clone, Serialize, Deserialize, JsonSchema)]
+pub struct FileInput {
+    pub path: String,
+    pub operation: FileOperation,
+    #[serde(skip_serializing_if = "Option::is_none")]
+    pub content: Option<String>,
+    #[serde(skip_serializing_if = "Option::is_none")]
+    pub position: Option<usize>,
+}
+
+impl AiTool for FileTool {
+    type Input = FileInput;
+    type Output = FileOutput;
+
+    fn name(&self) -> &str { "file" }
+
+    fn description(&self) -> &str {
+        "Read, write, and manipulate files"
+    }
+
+    fn operations(&self) -> &'static [&'static str] {
+        &["read", "append", "insert", "patch", "save"]
+    }
+
+    fn parameters_schema_filtered(&self, allowed_ops: &HashSet<String>) -> Value {
+        let mut schema = self.parameters_schema();
+        filter_schema_enum(&mut schema, "operation", allowed_ops);
+        schema
+    }
+
+    async fn execute(&self, params: FileInput, meta: &ExecutionMeta) -> Result<FileOutput> {
+        // Execution still validates at runtime as defense in depth
+        match params.operation {
+            FileOperation::Read => self.do_read(&params.path).await,
+            FileOperation::Append => self.do_append(&params.path, params.content.as_deref()).await,
+            // ... etc
+        }
+    }
+}
+```
+
+## Example: Agent Configuration
+
+```rust
+// In agent config or programmatic setup
+let rules = vec![
+    ToolRule {
+        tool_name: "file".to_string(),
+        rule_type: ToolRuleType::AllowedOperations(
+            ["read", "append"].into_iter().map(String::from).collect()
+        ),
+        conditions: vec![],
+        priority: 0,
+        metadata: None,
+    },
+];
+
+let builder = ContextBuilder::new(&memory, &config)
+    .for_agent("limited-agent")
+    .with_tool_rules(rules);
+```
+
+Or in TOML config:
+
+```toml
+[[tool_rules]]
+tool_name = "file"
+rule_type = { AllowedOperations = ["read", "append"] }
+priority = 0
+```
+
+## Runtime Execution Gating (Defense in Depth)
+
+While schema filtering prevents the LLM from seeing disallowed operations, we should also validate at execution time:
+
+```rust
+impl ToolRuleEngine {
+    /// Check if operation is allowed before execution
+    pub fn check_operation_allowed(
+        &self,
+        tool_name: &str,
+        operation: &str,
+    ) -> Result<(), ToolRuleViolation> {
+        if let Some(rule) = self.find_rule(tool_name, |r| {
+            matches!(r.rule_type, ToolRuleType::AllowedOperations(_))
+        }) {
+            if let ToolRuleType::AllowedOperations(ref allowed) = rule.rule_type {
+                if !allowed.contains(operation) {
+                    return Err(ToolRuleViolation::OperationNotAllowed {
+                        tool: tool_name.to_string(),
+                        operation: operation.to_string(),
+                        allowed: allowed.iter().cloned().collect(),
+                    });
+                }
+            }
+        }
+        Ok(())
+    }
+}
+
+// New violation type
+pub enum ToolRuleViolation {
+    // ... existing variants ...
+
+    OperationNotAllowed {
+        tool: String,
+        operation: String,
+        allowed: Vec<String>,
+    },
+}
+```
+
+## Integration with Data Sources
+
+This mechanism directly supports the data source v2 design where:
+
+- `file` tool operations are gated by agent capability config
+- `block_edit` tool operations (append, replace, patch, set_field) are gated per agent
+- DataBlock and DataStream sources declare `required_tools()` with specific operations
+
+Example from data source:
+
+```rust
+impl DataBlock for FileSource {
+    fn required_tools(&self) -> Vec<ToolRule> {
+        vec![
+            ToolRule {
+                tool_name: "file".to_string(),
+                rule_type: ToolRuleType::AllowedOperations(
+                    ["read", "append", "insert", "save"].into_iter().map(String::from).collect()
+                    // Note: "patch" not included - requires advanced capability
+                ),
+                conditions: vec![],
+                priority: 0,
+                metadata: None,
+            },
+        ]
+    }
+}
+```
+
+## Open Questions
+
+1. **Wildcard rules**: Should `tool_name = "*"` apply AllowedOperations to all tools? Probably not meaningful since operations are tool-specific.
+
+2. **Rule merging**: If multiple rules apply (e.g., from agent config and data source), should we union or intersect the allowed operations? Intersect is safer (most restrictive).
+
+3. **Dynamic operations**: Some tools might have operations that depend on runtime state. For now, operations are static (`&'static [&'static str]`). Could relax if needed.

+# Tool Rewrite & FileSource Design
+
+## Overview
+
+This design describes a new tool taxonomy for the v2 data source system, replacing the current `context` and `recall` tools with a cleaner separation of concerns. It also specifies FileSource as the first concrete DataBlock implementation.
+
+## Tool Taxonomy
+
+Five tools replacing the current system:
+
+| Tool | Purpose | Operations |
+|------|---------|------------|
+| `block` | Block lifecycle | load, pin, unpin, archive, info |
+| `block_edit` | Block content | append, replace, patch, set_field |
+| `recall` | Archival entries | insert, search |
+| `source` | Data source control | pause, resume, status, list |
+| `file` | File disk I/O + edits | load, save, create, delete, append, replace |
+
+### Key Relationships
+
+- `file load` creates a Working block from disk, then `block`/`block_edit` or `file` edit ops work on it
+- `block archive` changes BlockType (Working → Archival), does NOT create an archival entry
+- `recall insert` creates immutable archival entry (distinct from Archival-typed blocks)
+- `source` controls streams (pause/resume), shows status for all source types
+
+### Permission Model
+
+Two layers that compose:
+1. **FileSource rules** - Glob patterns → MemoryPermission (what's possible)
+2. **Agent tool rules** - `AllowedOperations` (what's allowed for this agent)
+
+### Deprecation Path
+
+- `context` tool remains but becomes outmoded
+- New agents use `block`/`block_edit`
+- Existing agents migrate over time
+
+---
+
+## Tool Specifications
+
+### `block` Tool
+
+**Purpose:** Manage block lifecycle - loading, pinning, archiving, querying info.
+
+**Operations:**
+
+| Op | Parameters | Description |
+|----|------------|-------------|
+| `load` | `label`, `source_id?` | Load block into working context. If source_id provided, delegates to source's load. |
+| `pin` | `label` | Set `pinned=true`, block stays in context across batches |
+| `unpin` | `label` | Set `pinned=false`, block becomes ephemeral |
+| `archive` | `label` | Change BlockType from Working → Archival |
+| `info` | `label` | Return block metadata: schema, type, permission, size, pinned status |
+
+**Input schema:**
+```rust
+pub struct BlockInput {
+    pub op: BlockOp,
+    pub label: String,
+    #[serde(skip_serializing_if = "Option::is_none")]
+    pub source_id: Option<String>,
+}
+
+pub enum BlockOp {
+    Load,
+    Pin,
+    Unpin,
+    Archive,
+    Info,
+}
+```
+
+**Tool rules:**
+- `ContinueLoop` - conversation continues after any operation
+- Operations gated via `AllowedOperations` at agent level
+
+**Implementation notes:**
+- Uses `ToolContext::memory()` for block access
+- `load` with `source_id` calls `SourceManager::load_block()`
+- `info` returns `BlockMetadata` formatted for agent consumption
+
+---
+
+### `block_edit` Tool
+
+**Purpose:** Edit block content with schema-aware operations.
+
+**Operations:**
+
+| Op | Parameters | Description |
+|----|------------|-------------|
+| `append` | `label`, `content` | Append text to block (Text, List schemas) |
+| `replace` | `label`, `old`, `new` | Find and replace text (Text schema initially, expandable) |
+| `patch` | `label`, `patch` | Apply diff/patch (advanced capability) |
+| `set_field` | `label`, `field`, `value` | Set specific field (Map, Composite schemas) |
+
+**Input schema:**
+```rust
+pub struct BlockEditInput {
+    pub op: BlockEditOp,
+    pub label: String,
+    #[serde(skip_serializing_if = "Option::is_none")]
+    pub content: Option<String>,
+    #[serde(skip_serializing_if = "Option::is_none")]
+    pub old: Option<String>,
+    #[serde(skip_serializing_if = "Option::is_none")]
+    pub new: Option<String>,
+    #[serde(skip_serializing_if = "Option::is_none")]
+    pub field: Option<String>,
+    #[serde(skip_serializing_if = "Option::is_none")]
+    pub value: Option<serde_json::Value>,
+    #[serde(skip_serializing_if = "Option::is_none")]
+    pub patch: Option<String>,
+}
+
+pub enum BlockEditOp {
+    Append,
+    Replace,
+    Patch,
+    SetField,
+}
+```
+
+**Schema compatibility:**
+- `append` → Text, List
+- `replace` → Text (expandable to other schemas later)
+- `set_field` → Map, Composite (respects `read_only` field flag)
+- `patch` → Text (requires AdvancedEdit capability)
+
+**Permission enforcement:**
+- Checks `MemoryPermission` on target block
+- `read_only` fields reject `set_field`
+- May trigger consent request for Human/Partner permission levels
+
+**Tool rules:**
+- `ContinueLoop`
+- `AllowedOperations` gates which ops agent can use
+
+---
+
+### `recall` Tool
+
+**Purpose:** Create and search immutable archival entries.
+
+**Operations:**
+
+| Op | Parameters | Description |
+|----|------------|-------------|
+| `insert` | `content`, `metadata?` | Create new immutable archival entry |
+| `search` | `query`, `limit?` | Full-text search over archival entries |
+
+**Input schema:**
+```rust
+pub struct RecallInput {
+    pub op: RecallOp,
+    #[serde(skip_serializing_if = "Option::is_none")]
+    pub content: Option<String>,
+    #[serde(skip_serializing_if = "Option::is_none")]
+    pub metadata: Option<serde_json::Value>,
+    #[serde(skip_serializing_if = "Option::is_none")]
+    pub query: Option<String>,
+    #[serde(skip_serializing_if = "Option::is_none")]
+    pub limit: Option<usize>,
+}
+
+pub enum RecallOp {
+    Insert,
+    Search,
+}
+```
+
+**Output:**
+- `insert` returns entry ID and confirmation
+- `search` returns `Vec<ArchivalSearchResult>` with label, content, timestamps, relevance score
+
+**Notes:**
+- Entries are immutable once created - no update/delete ops
+- Uses existing `insert_archival` / `search_archival` on MemoryStore
+- Archival-typed blocks may also surface in search results (TBD)
+- Simpler than current `recall` which has Append/Read/Delete
+
+**Tool rules:**
+- `ContinueLoop`
+
+---
+
+### `source` Tool
+
+**Purpose:** Control data sources and view status.
+
+**Operations:**
+
+| Op | Parameters | Description |
+|----|------------|-------------|
+| `pause` | `source_id` | Pause notifications from a stream source |
+| `resume` | `source_id` | Resume notifications |
+| `status` | `source_id?` | Get status of one source or all |
+| `list` | - | List all registered sources |
+
+**Input schema:**
+```rust
+pub struct SourceInput {
+    pub op: SourceOp,
+    #[serde(skip_serializing_if = "Option::is_none")]
+    pub source_id: Option<String>,
+}
+
+pub enum SourceOp {
+    Pause,
+    Resume,
+    Status,
+    List,
+}
+```
+
+**Output:**
+- `pause`/`resume` - confirmation message
+- `status` - `StreamSourceInfo` or `BlockSourceInfo` (type, name, status, schemas)
+- `list` - all sources with type indicator (stream vs block)
+
+**Stream vs Block behavior:**
+- `pause`/`resume` only valid for streams
+- For block sources, return informative message with current state (watching status, loaded blocks)
+- `status`/`list` work for both source types
+
+**Implementation:**
+- Uses `ToolContext::sources()` → `SourceManager`
+- Delegates to `pause_stream()`, `resume_stream()`, etc.
+
+**Tool rules:**
+- `ContinueLoop`
+
+---
+
+### `file` Tool
+
+**Purpose:** File disk I/O and editing operations for FileSource.
+
+**Operations:**
+
+| Op | Parameters | Description |
+|----|------------|-------------|
+| `load` | `path` | Load file from disk into Working block |
+| `save` | `path` or `label` | Persist block content back to disk |
+| `create` | `path`, `content?` | Create new file (and block) |
+| `delete` | `path` | Delete file from disk (escalation likely) |
+| `append` | `path`, `content` | Append to file (operates on block) |
+| `replace` | `path`, `old`, `new` | Find/replace in file |
+
+**Input schema:**
+```rust
+pub struct FileInput {
+    pub op: FileOp,
+    #[serde(skip_serializing_if = "Option::is_none")]
+    pub path: Option<String>,
+    #[serde(skip_serializing_if = "Option::is_none")]
+    pub label: Option<String>,
+    #[serde(skip_serializing_if = "Option::is_none")]
+    pub content: Option<String>,
+    #[serde(skip_serializing_if = "Option::is_none")]
+    pub old: Option<String>,
+    #[serde(skip_serializing_if = "Option::is_none")]
+    pub new: Option<String>,
+}
+
+pub enum FileOp {
+    Load,
+    Save,
+    Create,
+    Delete,
+    Append,
+    Replace,
+}
+```
+
+**Block label convention:** `file:{hash8}:{relative_path}`
+- `hash8` is truncated hash of absolute path
+- Avoids collisions with similarly named files in different locations
+- Agent sees relative path, internally resolves unambiguously
+
+**Permission enforcement:**
+- FileSource checks glob rules before any operation
+- `delete` typically requires escalation
+- Agent tool rules can further restrict
+
+**Sync model (v1):**
+- `load` reads disk → creates/updates block
+- `save` writes block → disk
+- No auto-reconcile; agent manages sync explicitly
+- Clear error if disk changed since load (mtime check)
+
+**Implementation:**
+- Registered by FileSource when active
+- Uses FileSource methods: `load()`, `save()`, `create()`, `delete()`
+- Edit ops delegate to underlying block via MemoryStore
+
+---
+
+## FileSource Implementation
+
+**Purpose:** First concrete DataBlock implementation - local filesystem with Loro overlay.
+
+### Core Structure
+
+```rust
+pub struct FileSource {
+    source_id: String,
+    base_path: PathBuf,
+    permission_rules: Vec<PermissionRule>,
+
+    // Loaded file tracking
+    loaded_blocks: DashMap<PathBuf, LoadedFileInfo>,
+}
+
+struct LoadedFileInfo {
+    block_id: String,
+    label: String,
+    disk_mtime: SystemTime,
+    disk_hash: u64,  // For conflict detection
+}
+```
+
+### DataBlock Trait Implementation
+
+- `load()` - Read file, create Text block with Loro backing, track mtime/hash
+- `save()` - Check mtime, write block content to disk, update tracking
+- `create()` - Create file + block
+- `delete()` - Permission check (likely escalation), remove file, cleanup block
+- `reconcile()` - Compare disk vs Loro, apply resolution strategy
+
+### Conflict Detection (v1 On-Demand)
+
+- `save` checks if `disk_mtime` changed since load
+- If changed: error with message "file modified externally, use `file load` to refresh"
+- No auto-merge in v1 - agent decides
+
+### Permission Integration
+
+- `permission_for(path)` matches against glob rules
+- Returns `MemoryPermission` level
+- Checked before load/save/create/delete
+
+### Tool Registration
+
+- FileSource registers `file` tool when started
+- Tool rules derived from permission_rules
+
+---
+
+## Integration
+
+### ToolContext Integration
+
+All new tools receive `Arc<dyn ToolContext>` (same pattern as existing):
+- Access memory via `ctx.memory()`
+- Access sources via `ctx.sources()` → `SourceManager`
+- Permission broker via `ctx.permission_broker()`
+
+### BuiltinTools Update
+
+```rust
+impl BuiltinTools {
+    pub fn v2_tools(ctx: Arc<dyn ToolContext>) -> Self {
+        Self {
+            block_tool: BlockTool::new(ctx.clone()),
+            block_edit_tool: BlockEditTool::new(ctx.clone()),
+            recall_tool: RecallTool::new(ctx.clone()),
+            source_tool: SourceTool::new(ctx.clone()),
+            // file tool registered dynamically by FileSource
+        }
+    }
+}
+```
+
+### Dynamic Tool Registration
+
+- FileSource registers `file` tool via `ToolRegistry` when started
+- Other DataBlock sources can register their own tools
+- DataStream sources may also register source-specific tools
+
+### Migration Path
+
+1. Implement new tools alongside existing
+2. New agents configured with v2 tools
+3. Existing agents continue using `context`/`recall`
+4. Gradually migrate as agents are updated
+5. Eventually deprecate old tools
+
+---
+
+## Open Questions / Future Work
+
+1. **Watch-driven reconciliation** - Background file watching with auto-reconcile (v2)
+2. **Shell hook integration** - Pre/post hooks for permission enforcement
+3. **Dynamic config updates** - Hot-reload of permission rules
+4. **`replace` expansion** - Support other schema types if parseable
+5. **Archival block search** - Whether `recall search` also surfaces Archival-typed blocks
+
+## Not In Scope
+
+- BlueskySource migration (separate effort, different atproto lib)
+- DiscordSource migration
+- MCP integration with sources

+# Tool Rewrite & FileSource Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Implement v2 tool taxonomy (block, block_edit, recall, source, file) and FileSource as first DataBlock implementation.
+
+**Architecture:** Five new tools with clean separation - lifecycle vs content editing, archival entries vs blocks, source control. FileSource implements DataBlock trait with Loro-backed blocks and on-demand disk sync.
+
+**Tech Stack:** Rust, tokio, serde, DashMap, Loro CRDT, SQLite (in-memory for tests)
+
+**Design Doc:** `docs/plans/2025-12-27-tool-rewrite-design.md`

+```
+
+**Step 4: Add missing MemoryStore methods if needed**
+
+Check if `set_block_pinned` and `set_block_type` exist on MemoryStore trait. If not, add them:
+
+```rust
+// In crates/pattern_core/src/memory/store.rs, add to trait:
+async fn set_block_pinned(&self, agent_id: &str, label: &str, pinned: bool) -> MemoryResult<()>;
+async fn set_block_type(&self, agent_id: &str, label: &str, block_type: BlockType) -> MemoryResult<()>;
+```
+
+And implement in MemoryCache.

+## Task 3: BlockEdit Tool Implementation
+
+**Files:**
+- Create: `crates/pattern_core/src/tool/builtin/block_edit.rs`
+- Modify: `crates/pattern_core/src/tool/builtin/tests.rs`
+
+**Step 1: Write failing test**
+
+```rust

+        .unwrap()
+        .unwrap();
+    assert_eq!(content, "Hello World");
+}
+```
+
+**Step 2: Run test to verify it fails**
+
+Run: `cargo test -p pattern_core block_edit_append -- --nocapture`
+Expected: FAIL - BlockEditTool not found
+
+**Step 3: Implement BlockEditTool**
+
+**IMPORTANT:** This tool works directly with `StructuredDocument`, NOT high-level MemoryStore methods.
+
+Pattern:
+1. `memory.get_block(agent_id, label)` → returns `Option<StructuredDocument>`
+2. Call methods on the document: `doc.append_text()`, `doc.replace_text()`, `doc.set_field()`
+3. `memory.persist_block(agent_id, label)` to save changes
+

+## Task 8: BuiltinTools Integration
+
+**Files:**
+- Modify: `crates/pattern_core/src/tool/builtin/mod.rs`
+
+**Step 1: Update BuiltinTools to include new tools**
+
+The existing `BuiltinTools` struct should be extended to include the new tools alongside existing ones:
+
+```rust
+// In crates/pattern_core/src/tool/builtin/mod.rs, update BuiltinTools struct and impl:
+
+pub struct BuiltinTools {
+    // Existing tools

+```
+
+**Step 2: Add test for new tool registration**
+
+```rust

+
+## Summary
+
+**Tools implemented:**
+1. `block` - lifecycle (load, pin, unpin, archive, info)
+2. `block_edit` - content (append, replace, patch stub, set_field)
+3. `recall` - archival entries (insert, search)
+4. `source` - data source control (pause, resume, status, list)
+5. `file` - FileSource operations (load, save, create, delete, append, replace)
+
+**FileSource implemented:**
+- DataBlock trait implementation
+- Loro-backed blocks for files
+- On-demand sync with conflict detection
+- Glob-based permission rules
+
+**Not yet implemented (future work):**
+- `patch` operation in block_edit
+- File watching (v2)
+- Rollback/history using Loro versions
+- Shell hook integration

+# FileSource & Block Editing Enhancements Design
+
+## Overview
+
+This design enhances the FileSource implementation and block editing utilities to provide:
+- Automatic bidirectional sync between memory blocks and disk via Loro subscriptions
+- File watching with permission-based conflict resolution
+- Smarter text editing using Loro's native operations
+- Unified diff format for input and output
+

+
+## Key Insight: Fork + Subscribe
+
+Rather than manual reconciliation, we leverage Loro's CRDT capabilities:
+
+1. On load, fork the memory doc to create a disk doc (shared history)
+2. Subscribe to local updates on both docs
+3. Memory changes → import to disk_doc → auto-save to filesystem
+4. Disk changes detected → update disk_doc → import to memory_doc
+
+`subscribe_local_update` only fires on local changes, not imports, preventing loops.

+
+## Data Structures
+
+### LoadedFileInfo
+
+```rust
+struct LoadedFileInfo {
+    block_id: String,
+    label: String,
+    disk_mtime: SystemTime,
+    disk_size: u64,
+
+    // Loro docs - forked, kept in sync via subscriptions
+    disk_doc: LoroDoc,
+
+    // Keep subscriptions alive
+    _subscriptions: (Subscription, Subscription),
+
+    // For explicit save tracking (if needed)
+    last_saved_frontier: VersionVector,
+}
+```
+
+### FileSource
+
+```rust
+pub struct FileSource {
+    source_id: String,
+    base_path: PathBuf,
+    permission_rules: Vec<PermissionRule>,
+    loaded_blocks: DashMap<PathBuf, LoadedFileInfo>,
+    status: AtomicU8,
+
+    // File watching
+    watcher: Option<Arc<RecommendedWatcher>>,
+    change_tx: Option<broadcast::Sender<FileChange>>,
+}
+```
+
+---
+
+## FileTool Operations
+
+### Extended FileOp Enum
+
+```rust
+#[derive(Debug, Clone, Copy, PartialEq, Eq, Serialize, Deserialize, JsonSchema)]
+#[serde(rename_all = "snake_case")]
+pub enum FileOp {
+    // Existing
+    Load,
+    Save,
+    Create,
+    Delete,
+    Append,
+    Replace,
+
+    // New
+    List,    // List files in source
+    Status,  // Check sync status
+    Diff,    // Show changes vs disk
+    Reload,  // Discard changes, re-read from disk
+}
+```
+
+### Extended FileInput (Flat Structure)
+
+```rust
+#[derive(Debug, Clone, Serialize, Deserialize, JsonSchema)]
+pub struct FileInput {
+    pub op: FileOp,
+
+    #[serde(default, skip_serializing_if = "Option::is_none")]
+    pub path: Option<String>,
+    #[serde(default, skip_serializing_if = "Option::is_none")]
+    pub label: Option<String>,
+    #[serde(default, skip_serializing_if = "Option::is_none")]
+    pub content: Option<String>,
+    #[serde(default, skip_serializing_if = "Option::is_none")]
+    pub old: Option<String>,
+    #[serde(default, skip_serializing_if = "Option::is_none")]
+    pub new: Option<String>,
+
+    // New fields
+    #[serde(default, skip_serializing_if = "Option::is_none")]
+    pub pattern: Option<String>,  // Glob for list op
+    #[serde(default, skip_serializing_if = "Option::is_none")]
+    pub include_loaded: Option<bool>,  // For list op
+}
+```
+
+### Operation Details
+
+**list** - Discover files in source
+- `pattern`: Optional glob (e.g., `"**/*.rs"`)
+- Returns: Array of `{path, size, permission, loaded, dirty}`
+
+**status** - Check sync state
+- `path`: Optional, specific file or all loaded
+- Returns: Array of `{path, label, sync_status, disk_mtime}`
+
+**diff** - Show changes between block and disk
+- `path`: Required
+- Returns: Unified diff with metadata header (in `message` field)
+
+**reload** - Discard block changes, re-read from disk
+- `path`: Required
+- Returns: Confirmation
+

+## Smarter Replace Operation
+
+Current implementation reads all content, does string replace, writes all content. This loses CRDT granularity.
+
+### Position Type Conversion
+
+**Critical**: Loro's `delete()` and `insert()` use **Unicode character indices**, not UTF-8 byte indices. Rust's `str::find()` and `str::len()` return byte indices. Use `LoroText::convert_pos()` to convert:
+
+```rust
+pub fn convert_pos(
+    &self,
+    index: usize,
+    from: PosType,
+    to: PosType,
+) -> Option<usize>
+
+pub enum PosType {
+    Bytes,      // UTF-8 byte offset (what Rust str methods return)
+    Unicode,    // Unicode scalar value count (what Loro uses internally)
+    Utf16,      // UTF-16 code unit count
+    Event,      // Event-based position
+    Entity,     // Entity-based position
+}
+```
+
+### New Approach
+
+Use Loro's native `delete()` + `insert()` with proper position conversion:
+
+```rust
+pub fn replace_text(
+    &self,
+    find: &str,
+    replace: &str,
+    is_system: bool,
+) -> Result<bool, DocumentError> {
+    self.check_permission(pattern_db::models::MemoryOp::Overwrite, is_system)?;
+
+    let text = self.doc.get_text("content");
+    let current = text.to_string();
+
+    if let Some(byte_pos) = current.find(find) {
+        // Convert byte indices to Unicode character indices
+        let unicode_pos = text.convert_pos(byte_pos, PosType::Bytes, PosType::Unicode)
+            .ok_or_else(|| DocumentError::InvalidPosition(byte_pos))?;
+
+        // Calculate find length in bytes, then convert to unicode
+        let find_byte_end = byte_pos + find.len();
+        let unicode_end = text.convert_pos(find_byte_end, PosType::Bytes, PosType::Unicode)
+            .ok_or_else(|| DocumentError::InvalidPosition(find_byte_end))?;
+        let unicode_len = unicode_end - unicode_pos;
+
+        // Surgical edit at found position (using Unicode indices)
+        // splice(pos, delete_len, insert_str) is atomic
+        text.splice(unicode_pos, unicode_len, replace)?;
+        Ok(true)
+    } else {
+        Ok(false)
+    }
+}
+```
+
+### Benefits
+
+- Proper CRDT semantics - each op is discrete in history
+- Better merge behavior for concurrent edits
+- Accurate attribution tracking
+- Foundation for stable cursors
+- Correct handling of multi-byte UTF-8 characters (emoji, CJK, etc.)

+
+## File Watching
+
+### Watcher Setup
+
+```rust
+impl FileSource {
+    pub fn start_watching(&mut self) -> Result<broadcast::Receiver<FileChange>> {
+        let (tx, rx) = broadcast::channel(256);
+
+        let tx_clone = tx.clone();
+        let loaded_blocks = self.loaded_blocks.clone();
+
+        let watcher = notify::recommended_watcher(move |res: Result<Event, _>| {
+            if let Ok(event) = res {
+                for path in event.paths {
+                    // Only emit for tracked files
+                    if loaded_blocks.contains_key(&path) {
+                        let change = FileChange {
+                            path: path.clone(),
+                            change_type: event.kind.into(),
+                            block_id: loaded_blocks.get(&path)
+                                .map(|info| info.block_id.clone()),
+                            timestamp: Some(Utc::now()),
+                        };
+                        let _ = tx_clone.send(change);
+                    }
+                }
+            }
+        })?;
+
+        watcher.watch(&self.base_path, RecursiveMode::Recursive)?;
+
+        self.watcher = Some(Arc::new(watcher));
+        self.change_tx = Some(tx);
+        self.status.store(STATUS_WATCHING, Ordering::SeqCst);
+
+        Ok(rx)
+    }
+}
+```
+
+### On File Change
+
+```rust
+async fn handle_file_change(&self, path: &Path) -> Result<()> {
+    let disk_content = tokio::fs::read_to_string(path).await?;
+
+    if let Some(mut info) = self.loaded_blocks.get_mut(path) {
+        // Update disk doc - subscription auto-syncs to memory
+        let disk_text = info.disk_doc.get_text("content");
+        disk_text.update(&disk_content, Default::default())?;
+        info.disk_doc.commit();
+        info.disk_mtime = self.get_file_metadata(path).await?.0;
+    }
+
+    Ok(())
+}
+```
+
+---
+
+## Load with Fork + Subscribe
+
+```rust
+async fn load(&self, path: &Path, ctx: Arc<dyn ToolContext>, owner: AgentId) -> Result<BlockRef> {
+    let content = tokio::fs::read_to_string(&abs_path).await?;
+    let (mtime, size) = self.get_file_metadata(path).await?;
+
+    // Create/update memory block
+    let memory = ctx.memory();
+    // ... existing block creation logic ...
+
+    let doc = memory.get_block(agent_id, &label).await?.unwrap();
+    let memory_loro = doc.inner().clone();
+
+    // Fork to create disk doc (shares history)
+    let disk_doc = memory_loro.fork();
+
+    // Subscribe: memory changes → import to disk_doc → auto-save
+    let disk_clone = disk_doc.clone();
+    let path_clone = abs_path.clone();
+    let mem_sub = memory_loro.subscribe_local_update(Box::new(move |update| {
+        let _ = disk_clone.import(&update);
+        let content = disk_clone.get_text("content").to_string();
+        let path = path_clone.clone();
+        tokio::spawn(async move {
+            let _ = tokio::fs::write(&path, &content).await;
+        });
+    }));
+
+    // Subscribe: disk changes → import to memory (no write-back)
+    let mem_clone = memory_loro.clone();
+    let disk_sub = disk_doc.subscribe_local_update(Box::new(move |update| {
+        let _ = mem_clone.import(&update);
+    }));
+
+    self.loaded_blocks.insert(abs_path.clone(), LoadedFileInfo {
+        block_id: block_id.clone(),
+        label: label.clone(),
+        disk_mtime: mtime,
+        disk_size: size,
+        disk_doc,
+        _subscriptions: (mem_sub, disk_sub),
+        last_saved_frontier: memory_loro.oplog_vv(),
+    });
+
+    Ok(block_ref)
+}
+```
+
+---
+
+## Permission-Based Subscription Setup
+
+Different permissions get different subscription configurations:
+
+```rust
+match permission {
+    MemoryPermission::ReadOnly => {
+        // Disk → memory only (agent can't edit)
+        let mem_clone = memory_loro.clone();
+        let disk_sub = disk_doc.subscribe_local_update(Box::new(move |update| {
+            let _ = mem_clone.import(&update);
+        }));
+        // No memory → disk subscription
+    }
+
+    MemoryPermission::ReadWrite => {
+        // Bidirectional - disk changes win conflicts (CRDT merge)
+        // Both subscriptions as shown above
+    }
+
+    MemoryPermission::Admin => {
+        // Bidirectional - agent changes win conflicts (CRDT merge)
+        // Both subscriptions as shown above
+        // Agent edits have "priority" in CRDT semantics
+    }
+
+    MemoryPermission::Human | MemoryPermission::Partner => {
+        // Bidirectional, but conflicts surfaced to agent
+        // May need additional conflict detection logic
+    }
+}
+```
+
+---
+
+## Patch Operation (Unified Diff Input)
+
+### BlockEditOp Extension
+
+```rust
+pub enum BlockEditOp {
+    Append,
+    Replace,
+    Patch,     // Accepts unified diff
+    SetField,
+}
+```
+
+### Parsing & Application
+
+```rust
+async fn handle_patch(&self, label: &str, patch: Option<String>) -> Result<ToolOutput> {
+    let patch = patch.ok_or_else(|| /* error */)?;
+
+    let doc = memory.get_block(agent_id, label).await?.ok_or_else(|| /* error */)?;
+    let text = doc.inner().get_text("content");
+    let current = text.to_string();
+
+    // Parse hunks from unified diff
+    let hunks = parse_unified_diff(&patch)?;
+
+    // Apply hunks in reverse order (so line numbers stay valid)
+    for hunk in hunks.into_iter().rev() {
+        let start_line = hunk.old_start - 1; // 0-indexed
+
+        // Calculate byte offset for the start of the target line
+        let byte_offset = line_to_byte_offset(&current, start_line);
+
+        // Calculate byte length of content to delete
+        let delete_byte_len: usize = hunk.old_lines.iter()
+            .map(|l| l.len() + 1) // +1 for newline
+            .sum();
+
+        // Convert byte positions to Unicode character positions
+        let unicode_start = text.convert_pos(byte_offset, PosType::Bytes, PosType::Unicode)
+            .ok_or_else(|| PatchError::InvalidPosition(byte_offset))?;
+        let unicode_end = text.convert_pos(byte_offset + delete_byte_len, PosType::Bytes, PosType::Unicode)
+            .ok_or_else(|| PatchError::InvalidPosition(byte_offset + delete_byte_len))?;
+        let unicode_delete_len = unicode_end - unicode_start;
+
+        // Atomic splice: delete old content and insert new (using Unicode indices)
+        let new_content = hunk.new_lines.join("\n") + "\n";
+        text.splice(unicode_start, unicode_delete_len, &new_content)?;
+    }
+
+    memory.persist_block(agent_id, label).await?;
+
+    Ok(ToolOutput::success(format!(
+        "Applied {} hunks to '{}'",
+        hunks.len(),
+        label
+    )))
+}
+
+/// Calculate byte offset for the start of a given line (0-indexed)
+fn line_to_byte_offset(content: &str, target_line: usize) -> usize {
+    content.lines()
+        .take(target_line)
+        .map(|l| l.len() + 1) // +1 for newline
+        .sum()
+}
+```
+
+### Unified Diff Parsing
+
+Using the `patch` crate (v0.7) for parsing unified diffs instead of a custom parser.
+The crate provides `Patch::from_single()` which returns hunks with `old_range`, `new_range`,
+and `lines: Vec<Line>` where `Line` is `Add(str)`, `Remove(str)`, or `Context(str)`.
+
+---
+
+## Implementation Phases
+
+### Phase 1 - Foundation & Safety
+
+- [X] Add `list` operation to FileTool
+- [X] Add `status` operation
+- [X] Smarter `replace` using Loro's `splice()` with `convert_pos()`
+- [X] Fix auto-load to not overwrite (check if already loaded)
+
+### Phase 2 - Watching & Auto-Sync
+
+- [X] Fork disk_doc on load
+- [X] Bidirectional subscriptions with auto-save
+- [X] File watching via `notify` crate
+- [X] Permission-based subscription setup
+- [X] `diff` operation with unified format + metadata header
+- [X] `reload` operation
+
+### Phase 3 - Smart Editing
+
+- [X] `patch` operation accepting unified diff (in BlockEditTool, uses `patch` crate)
+- [X] Line endings normalized to Unix (`\n`) on all file reads
+- [X] `replace` options: first/all/nth, regex (via `ReplaceMode` enum and `mode` field)
+- [X] Line-range editing via `edit_range` operation (parses "START-END: content" from content field)
+
+### Phase 4 - History & Undo (Future)
+
+- [ ] Version history via Loro frontiers
+- [ ] `history` / `rollback` operations
+- [ ] Undo/redo exposure
+
+---
+
+## Open Questions
+
+1. ~~**Line endings**~~ - RESOLVED: All file reads normalized to Unix (`\n`) via `normalize_line_endings()`. Windows `\r\n` converted on read; writes always use `\n`.
+2. **Large file handling** - May need streaming for very large files
+3. **Binary files** - Currently Text schema only; binary files need different handling
+4. **Subscription lifecycle** - Need to clean up subscriptions when blocks are unloaded
+5. **Splice error handling** - Verify `splice()` returns appropriate errors for out-of-bounds positions

+# Multi-Provider OAuth Support Design
+
+**Date:** 2025-12-28
+**Status:** Draft
+**Scope:** Add OAuth support for OpenAI Codex and Gemini (Cloud Code Companion)
+
+## Overview
+
+Extend Pattern's OAuth infrastructure to support three providers:
+- **Anthropic** (existing) - Standard OAuth with header/system prompt transformation
+- **OpenAI Codex** (new) - OAuth via ChatGPT Plus/Pro backend
+- **Gemini Cloud Code** (new) - OAuth via Google's Cloud Code Companion API
+
+## Key Finding: These Are Different APIs
+
+Both new providers use OAuth to access **internal APIs**, not the standard public APIs:
+
+| Provider | Standard API | OAuth API |
+|----------|-------------|-----------|
+| OpenAI | `api.openai.com` | `chatgpt.com/backend-api/codex/responses` |
+| Gemini | `generativelanguage.googleapis.com` | `cloudcode-pa.googleapis.com/v1internal:*` |
+
+This means we need new adapters in rust-genai, not just middleware.
+
+---
+
+## Architecture
+
+### rust-genai Fork
+
+New adapters handle the API differences:
+
+```
+rust-genai/src/adapter/adapters/
+├── anthropic/          # Existing
+├── openai/             # Existing (API key)
+├── openai_codex/       # NEW - OAuth via ChatGPT backend
+├── gemini/             # Existing (API key)
+└── cloud_code/         # NEW - Gemini OAuth via Cloud Code Companion
+```
+
+```rust
+pub enum AdapterKind {
+    Anthropic,
+    OpenAI,
+    OpenAICodex,    // NEW
+    Gemini,
+    CloudCode,      // NEW
+    // ...
+}
+```
+
+### pattern_core
+
+OAuth flow and auth resolver:
+
+```
+pattern_core/src/oauth/
+├── mod.rs              # OAuthProvider enum, OAuthClient
+├── auth_flow.rs        # PKCE, token exchange
+├── resolver.rs         # Auth resolver for genai
+├── integration.rs      # OAuthModelProvider
+└── loopback.rs         # NEW - Local callback server
+```
+
+---
+
+## Phase 1: OpenAI Codex
+
+### OAuth Configuration
+
+```rust
+impl OAuthConfig {
+    pub fn openai() -> Self {
+        Self {
+            client_id: "app_EMoamEEZ73f0CkXaXp7hrann".to_string(),
+            auth_endpoint: "https://auth.openai.com/oauth/authorize".to_string(),
+            token_endpoint: "https://auth.openai.com/oauth/token".to_string(),
+            redirect_uri: "http://localhost:1455/auth/callback".to_string(),
+            scopes: vec![
+                "openid".to_string(),
+                "profile".to_string(),
+                "email".to_string(),
+                "offline_access".to_string(),
+            ],
+        }
+    }
+}
+```
+
+### Extra Authorization Parameters
+
+```rust
+// Added to auth URL
+id_token_add_organizations = true
+codex_cli_simplified_flow = true
+originator = codex_cli_rs
+```
+
+### OpenAICodex Adapter (rust-genai)
+
+**Endpoint:** `https://chatgpt.com/backend-api/codex/responses`
+
+**Required Headers:**
+```
+Authorization: Bearer <access_token>
+chatgpt-account-id: <extracted_from_jwt>
+OpenAI-Beta: responses=experimental
+originator: codex_cli_rs
+accept: text/event-stream
+```
+
+**JWT Account ID Extraction:**
+```rust
+fn extract_account_id(access_token: &str) -> Result<String> {
+    // Decode JWT, extract claim at path:
+    // `https://api.openai.com/auth` -> `chatgpt_account_id`
+}
+```
+
+**Request Body Transformations:**
+```rust
+body.store = Some(false);           // Stateless mode
+body.stream = Some(true);           // Always stream
+body.instructions = Some(prompts);  // System prompt injection
+body.include = Some(vec!["reasoning.encrypted_content".to_string()]);
+
+// Remove unsupported fields
+body.max_output_tokens = None;
+body.max_completion_tokens = None;
+```
+
+**Model Normalization:**
+```rust
+const MODEL_MAP: &[(&str, &str)] = &[
+    ("gpt-5.2-codex", "gpt-5.2-codex"),
+    ("gpt-5.1-codex", "gpt-5.1-codex"),
+    ("codex", "gpt-5.1-codex"),
+    ("gpt-5", "gpt-5.1"),
+    // Strip suffixes like -low, -medium, -high (reasoning effort)
+];
+```
+
+**Reasoning Configuration:**
+```rust
+struct ReasoningConfig {
+    effort: String,  // none/minimal/low/medium/high/xhigh
+    summary: String, // auto/concise/detailed/off/on
+}
+
+// Model-specific constraints
+// - gpt-5.2-codex: supports xhigh, no "none"
+// - codex-mini: minimum "medium"
+// - gpt-5.1: no xhigh, supports "none"
+```
+
+**Response Handling:**
+
+SSE stream to JSON conversion for non-streaming:
+```rust
+fn parse_sse_to_json(stream: &str) -> Option<Value> {
+    for line in stream.lines() {
+        if let Some(data) = line.strip_prefix("data: ") {
+            if let Ok(parsed) = serde_json::from_str::<Value>(data) {
+                if parsed["type"] == "response.done"
+                    || parsed["type"] == "response.completed" {
+                    return Some(parsed["response"].clone());
+                }
+            }
+        }
+    }
+    None
+}
+```
+
+**System Prompt Injection:**
+
+Codex requires specific system prompts fetched from GitHub:
+- Model-family specific prompts (gpt-5.2-codex, gpt-5.1-codex, etc.)
+- `TOOL_REMAP_MESSAGE` - Maps Codex tools to Pattern tools
+- `CODEX_OPENCODE_BRIDGE` - Environment bridging (~550 tokens)
+
+```rust
+// Tool remapping critical content
+const TOOL_REMAP: &str = r#"
+❌ APPLY_PATCH DOES NOT EXIST → ✅ USE "edit" INSTEAD
+❌ UPDATE_PLAN DOES NOT EXIST → ✅ USE "todowrite" INSTEAD
+"#;
+```
+
+### Phase 1 Tasks
+
+**rust-genai:**
+1. Fix `exec_chat()` to handle `AuthData::RequestOverride` (bug)
+2. Add `AdapterKind::OpenAICodex`
+3. Implement `openai_codex` adapter module
+   - URL construction
+   - Header building with JWT parsing
+   - Request body transformation
+   - Model normalization
+   - SSE response parsing
+
+**pattern_core:**
+1. Add `OAuthProvider::OpenAI`
+2. Add `OAuthConfig::openai()`
+3. Add extra auth params support to `DeviceAuthFlow`
+4. Implement loopback callback server
+5. Extend auth resolver for `AdapterKind::OpenAICodex`
+6. Add Codex system prompt fetching and caching
+
+**pattern_cli:**
+1. Accept `openai` in auth commands
+
+---
+
+## Phase 2: Gemini Cloud Code
+
+### OAuth Configuration
+
+```rust
+impl OAuthConfig {
+    pub fn gemini() -> Self {
+        Self {
+            client_id: "681255809395-oo8ft2oprdrnp9e3aqf6av3hmdib135j.apps.googleusercontent.com".to_string(),
+            client_secret: Some("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".to_string()),
+            auth_endpoint: "https://accounts.google.com/o/oauth2/v2/auth".to_string(),
+            token_endpoint: "https://oauth2.googleapis.com/token".to_string(),
+            redirect_uri: "http://localhost:8085/oauth2callback".to_string(),
+            scopes: vec![
+                "https://www.googleapis.com/auth/cloud-platform".to_string(),
+                "https://www.googleapis.com/auth/userinfo.email".to_string(),
+                "https://www.googleapis.com/auth/userinfo.profile".to_string(),
+            ],
+        }
+    }
+}
+```
+
+### Extra Authorization Parameters
+
+```rust
+access_type = offline    // Get refresh token
+prompt = consent         // Force consent screen
+```
+
+### State Encoding (Different from Anthropic/OpenAI)
+
+PKCE verifier embedded in OAuth state as base64url JSON:
+```rust
+fn encode_state(verifier: &str) -> String {
+    let payload = json!({ "verifier": verifier });
+    base64::engine::general_purpose::URL_SAFE_NO_PAD
+        .encode(payload.to_string().as_bytes())
+}
+```
+
+### CloudCode Adapter (rust-genai)
+
+**Endpoint:** `https://cloudcode-pa.googleapis.com`
+
+**URL Transformation:**
+```rust
+// Standard Gemini:
+// /v1beta/models/{model}:generateContent
+
+// Cloud Code:
+// /v1internal:generateContent
+// /v1internal:streamGenerateContent?alt=sse
+```
+
+**Required Headers:**
+```
+Authorization: Bearer <access_token>
+User-Agent: google-api-nodejs-client/9.15.1
+X-Goog-Api-Client: gl-node/22.17.0
+Client-Metadata: ideType=IDE_UNSPECIFIED,platform=PLATFORM_UNSPECIFIED,pluginType=GEMINI
+Content-Type: application/json
+Accept: text/event-stream  // For streaming
+```
+
+**Request Body Wrapping:**
+```rust
+// Input
+{
+    "contents": [...],
+    "system_instruction": {...},
+    "generationConfig": {...}
+}
+
+// Transformed (wrapped)
+{
+    "project": "<project_id>",
+    "model": "<model_name>",
+    "request": {
+        "contents": [...],
+        "systemInstruction": {...},    // camelCase
+        "generationConfig": {...}
+    }
+}
+```
+
+**Field Renaming:**
+```rust
+const FIELD_RENAMES: &[(&str, &str)] = &[
+    ("system_instruction", "systemInstruction"),
+    ("cached_content", "cachedContent"),
+    ("thinking_budget", "thinkingBudget"),
+    ("thinking_level", "thinkingLevel"),
+    ("include_thoughts", "includeThoughts"),
+];
+```
+
+**Response Unwrapping:**
+```rust
+// API returns
+{ "response": { "candidates": [...], "usageMetadata": {...} } }
+
+// Unwrap to
+{ "candidates": [...], "usageMetadata": {...} }
+```
+
+**Streaming Response:**
+Transform each SSE line to unwrap the `response` field.
+
+### Project Management
+
+First-time setup requires project onboarding:
+
+```rust
+// 1. Check existing project
+POST /v1internal:loadCodeAssist
+{
+    "metadata": {
+        "ideType": "IDE_UNSPECIFIED",
+        "platform": "PLATFORM_UNSPECIFIED",
+        "pluginType": "GEMINI"
+    }
+}
+
+// 2. If no project, onboard to free tier
+POST /v1internal:onboardUser
+{
+    "tierId": "FREE",
+    "metadata": {...}
+}
+
+// Response contains cloudaicompanionProject ID to store
+```
+
+**Project ID Storage:**
+
+Store alongside refresh token using pipe delimiter:
+```
+<refresh_token>|<project_id>
+```
+
+Or add dedicated field to `ProviderOAuthToken`:
+```rust
+pub struct ProviderOAuthToken {
+    // ... existing fields
+    pub project_id: Option<String>,  // For Gemini
+}
+```
+
+### Phase 2 Tasks
+
+**rust-genai:**
+1. Add `AdapterKind::CloudCode`
+2. Implement `cloud_code` adapter module
+   - URL construction (`/v1internal:*`)
+   - Header building
+   - Request body wrapping
+   - Field renaming (snake_case → camelCase)
+   - Response unwrapping
+   - Streaming SSE transformation
+
+**pattern_core:**
+1. Add `OAuthProvider::Gemini`
+2. Add `OAuthConfig::gemini()` with client secret support
+3. Implement state encoding with embedded verifier
+4. Extend token exchange for client secret
+5. Add project management flow
+   - `loadCodeAssist` call
+   - `onboardUser` call
+   - Project ID storage
+6. Extend auth resolver for `AdapterKind::CloudCode`
+
+**pattern_auth:**
+1. Potentially add `project_id` field to `ProviderOAuthToken`
+
+**pattern_cli:**
+1. Accept `gemini` in auth commands
+2. Handle project onboarding UX (first login)
+
+---
+
+## Phase 3: Polish
+
+1. **Loopback server refinements**
+   - Headless detection (SSH)
+   - Manual paste fallback
+   - Configurable timeout
+   - Success HTML page
+
+2. **Error handling**
+   - Rate limit header parsing (Codex)
+   - Retry-After extraction (Gemini)
+   - Token revocation handling
+   - Gemini 3 preview access errors
+
+3. **Token refresh edge cases**
+   - 60-second expiry buffer
+   - Refresh token rotation (Gemini may return new refresh token)
+   - Invalid grant handling (re-auth required)
+
+4. **Testing**
+   - Mock OAuth flows
+   - Adapter unit tests
+   - Integration tests with real tokens (manual)
+
+---
+
+## Loopback Server Design
+
+Shared infrastructure for OAuth callbacks:
+
+```rust
+pub struct LoopbackConfig {
+    pub host: String,           // "127.0.0.1"
+    pub port: u16,              // Provider-specific
+    pub path: String,           // "/auth/callback" or "/oauth2callback"
+    pub timeout: Duration,      // 5 minutes
+    pub open_browser: bool,     // Auto-open auth URL
+}
+
+impl LoopbackConfig {
+    pub fn openai() -> Self {
+        Self {
+            host: "127.0.0.1".to_string(),
+            port: 1455,
+            path: "/auth/callback".to_string(),
+            timeout: Duration::from_secs(300),
+            open_browser: true,
+        }
+    }
+
+    pub fn gemini() -> Self {
+        Self {
+            host: "127.0.0.1".to_string(),
+            port: 8085,
+            path: "/oauth2callback".to_string(),
+            timeout: Duration::from_secs(300),
+            open_browser: true,
+        }
+    }
+}
+```
+
+**Implementation pattern from jacquard:**
+- Use `rouille` for simple one-shot HTTP server
+- Channel to receive callback params
+- Stoppable server that shuts down after callback
+- Timeout handling with `tokio::time::timeout`
+
+---
+
+## Dependencies
+
+**rust-genai (new):**
+- `jsonwebtoken` - JWT parsing for Codex account ID
+- `base64` - State encoding for Gemini
+
+**pattern_core (new):**
+- `rouille` - Loopback server (or reuse existing `axum`)
+- `webbrowser` - Optional browser auto-open
+
+---
+
+## Cleanup: Centralized Auth Configuration
+
+Currently, API key availability is checked in multiple places:
+
+**model.rs** (`GenAiClient::new()`):
+```rust
+if std::env::var("ANTHROPIC_API_KEY").is_ok() {
+    available_endpoints.push(AdapterKind::Anthropic);
+}
+// Repeated for each provider
+```
+
+**resolver.rs** (`create_oauth_auth_resolver()`):
+```rust
+if std::env::var("ANTHROPIC_API_KEY").is_ok() {
+    return Ok(None);  // Fall back to API key
+}
+```
+
+### Problem
+
+- Duplicated logic
+- Easy to get out of sync
+- Doesn't account for OAuth tokens in endpoint discovery
+- Adding new providers requires changes in multiple places
+
+### Proposed Solution
+
+Centralize auth configuration into a single source of truth:
+
+```rust
+/// Tracks available authentication methods for each provider
+pub struct AuthConfig {
+    providers: HashMap<AdapterKind, AuthMethod>,
+}
+
+pub enum AuthMethod {
+    ApiKey,           // Environment variable available
+    OAuth,            // OAuth token stored
+    Both,             // Both available (prefer OAuth)
+    None,             // Not configured
+}
+
+impl AuthConfig {
+    /// Build config by checking env vars and OAuth token storage
+    pub async fn discover(auth_db: &AuthDb) -> Self {
+        let mut providers = HashMap::new();
+
+        for kind in [AdapterKind::Anthropic, AdapterKind::OpenAI, AdapterKind::Gemini, ...] {
+            let has_api_key = Self::check_api_key(&kind);
+            let has_oauth = auth_db.get_provider_oauth_token(kind.as_str()).await.ok().flatten().is_some();
+
+            let method = match (has_api_key, has_oauth) {
+                (true, true) => AuthMethod::Both,
+                (true, false) => AuthMethod::ApiKey,
+                (false, true) => AuthMethod::OAuth,
+                (false, false) => AuthMethod::None,
+            };
+
+            providers.insert(kind, method);
+        }
+
+        Self { providers }
+    }
+
+    fn check_api_key(kind: &AdapterKind) -> bool {
+        let var_name = match kind {
+            AdapterKind::Anthropic => "ANTHROPIC_API_KEY",
+            AdapterKind::OpenAI => "OPENAI_API_KEY",
+            AdapterKind::Gemini => "GEMINI_API_KEY",
+            // ... etc
+        };
+        std::env::var(var_name).is_ok()
+    }
+
+    /// Get available endpoints (any auth method configured)
+    pub fn available_endpoints(&self) -> Vec<AdapterKind> {
+        self.providers.iter()
+            .filter(|(_, method)| !matches!(method, AuthMethod::None))
+            .map(|(kind, _)| *kind)
+            .collect()
+    }
+
+    /// Check if OAuth should be used for a provider
+    pub fn should_use_oauth(&self, kind: &AdapterKind) -> bool {
+        matches!(
+            self.providers.get(kind),
+            Some(AuthMethod::OAuth) | Some(AuthMethod::Both)
+        )
+    }
+}
+```
+
+### Usage
+
+**model.rs:**
+```rust
+impl GenAiClient {
+    pub async fn new(auth_config: &AuthConfig) -> Result<Self> {
+        let client = genai::Client::default();
+        let available_endpoints = auth_config.available_endpoints();
+        Ok(Self { client, available_endpoints })
+    }
+}
+```
+
+**resolver.rs:**
+```rust
+pub fn create_oauth_auth_resolver(auth_db: AuthDb, auth_config: AuthConfig) -> AuthResolver {
+    // Use auth_config to determine whether to try OAuth or fall back to API key
+}
+```
+
+### When to Implement
+
+This cleanup can be done:
+1. **Before** multi-provider OAuth (cleaner foundation)
+2. **During** Phase 1 (OpenAI Codex) - refactor as we add
+3. **After** Phase 2 (Gemini) - once all providers are in
+
+Recommendation: Do it during Phase 1 to avoid accumulating more tech debt.
+
+---
+
+## Open Questions
+
+1. **System prompt fetching for Codex** - Cache locally or fetch on each request?
+   - Recommendation: Cache with ETag-based conditional requests, 15-minute TTL
+
+2. **Gemini project ID storage** - Separate field or embed in refresh token?
+   - Recommendation: Separate field in `ProviderOAuthToken` for clarity
+
+3. **Adapter naming** - `CloudCode` vs `GeminiCloudCode` vs `GeminiOAuth`?
+   - Recommendation: `CloudCode` - it's a distinct API, not just "Gemini with OAuth"
+
+4. **Loopback server** - `rouille` (lightweight) vs `axum` (already a dep)?
+   - Either works; `axum` avoids new dependency

+# Block Share Operation Design
+
+Add `share` and `unshare` operations to the block tool, allowing agents to share blocks with other agents by name.
+
+## Overview
+
+Agents need to share memory blocks with each other for collaboration. This design adds share/unshare operations to the existing block tool, using the existing `SharedBlockManager` infrastructure.
+
+## Changes Required
+
+### 1. ToolContext Trait (tool_context.rs)
+
+Add method to expose SharedBlockManager:
+
+```rust
+fn shared_blocks(&self) -> Option<Arc<SharedBlockManager>>;
+```
+
+### 2. AgentRuntime (runtime/mod.rs)
+
+- Add field: `shared_blocks: Arc<SharedBlockManager>`
+- Initialize in `RuntimeBuilder::build()` using existing `dbs`
+- Implement trait method returning `Some(self.shared_blocks.clone())`
+
+### 3. BlockOp Enum (tool/builtin/types.rs)
+
+Add variants:
+
+```rust
+/// Share block with another agent
+Share,
+/// Remove sharing from another agent
+Unshare,
+```
+
+### 4. BlockInput Struct (tool/builtin/types.rs)
+
+Add fields:
+
+```rust
+/// Target agent name for share/unshare operations
+#[serde(default, skip_serializing_if = "Option::is_none")]
+pub target_agent: Option<String>,
+
+/// Permission level for share operation (default: Append)
+#[serde(default, skip_serializing_if = "Option::is_none")]
+pub permission: Option<MemoryPermission>,
+```
+
+### 5. BlockTool Implementation (tool/builtin/block.rs)
+
+Add Share handler:
+1. Validate `target_agent` is provided
+2. Get `SharedBlockManager` from context (error if None)
+3. Look up target agent by name via `pattern_db::queries::get_agent_by_name`
+4. Get block metadata to find block ID
+5. Call `shared_blocks.share_block(block_id, target_agent_id, permission)`
+6. Default permission to `MemoryPermission::Append` if not specified
+7. Return success with sharing details
+
+Add Unshare handler:
+1. Validate `target_agent` is provided
+2. Get `SharedBlockManager` from context
+3. Look up target agent by name
+4. Get block metadata to find block ID
+5. Call `shared_blocks.unshare_block(block_id, target_agent_id)`
+6. Return success message
+
+### 6. Update Tool Description (tool/builtin/block.rs)
+
+Update `description()` to include:
+```
+- 'share': Share block with another agent by name (optional 'permission', default: Append)
+- 'unshare': Remove sharing from another agent by name
+```
+
+Update `operations()` to include `"share"` and `"unshare"`.
+
+### 7. Mock Implementation Updates
+
+Update `MockMemoryStore` and test utilities to handle the new `shared_blocks()` method (return `None` for basic mocks).
+
+### 8. Tests
+
+Add tests in block.rs:
+- `test_block_tool_share_operation` - share with default permission
+- `test_block_tool_share_with_explicit_permission` - share with ReadWrite
+- `test_block_tool_unshare_operation` - remove sharing
+- `test_block_tool_share_agent_not_found` - error when target agent doesn't exist
+- `test_block_tool_share_block_not_found` - error when block doesn't exist
+
+## Implementation Order
+
+1. Add `shared_blocks()` to ToolContext trait
+2. Add SharedBlockManager field to AgentRuntime and implement trait method
+3. Add Share/Unshare to BlockOp enum
+4. Add target_agent/permission fields to BlockInput
+5. Implement Share handler in BlockTool
+6. Implement Unshare handler in BlockTool
+7. Update tool description and operations list
+8. Add tests
+9. Update any mock implementations as needed
+
+## Notes
+
+- Uses existing `SharedBlockManager` from `crates/pattern_core/src/memory/sharing.rs`
+- Uses existing `get_agent_by_name` query from `crates/pattern_db/src/queries/agent.rs`
+- Permission defaults to `Append` (can read and append, but not overwrite)
+- Agents identify each other by name, not ID (more natural for agent-to-agent interaction)

+# Interactive Agent & Group Builder CLI
+
+Design for smart interactive configuration of agents and groups via the command line.
+
+## Overview
+
+A unified builder system for creating and editing agents and groups interactively. Supports multiple workflows:
+- Start from defaults, build interactively, save to DB and/or file
+- Load existing agent/group from DB, modify, update in place
+- Import from TOML file, customize, save anywhere
+
+## Command Structure
+
+### AgentCommands
+
+```
+List                        # List all agents
+Status <name>               # Show agent details
+Create [--from <path>]      # Interactive builder, new agent
+Edit <name>                 # Interactive builder, update existing
+Export <name> [path]        # Export config to TOML file
+Add <subcommand>            # Quick additions without full builder
+  - Source <name> <source>
+  - Memory <name> <label> [--content | --path]
+  - Tool <name> <tool>
+  - Rule <name> <tool> <rule-type> [options]
+Remove <subcommand>         # Quick removals
+  - Source <name> <source>
+  - Memory <name> <label>
+  - Tool <name> <tool>
+  - Rule <name> <tool> [rule-type]
+```
+
+### GroupCommands
+
+```
+List                        # List all groups
+Status <name>               # Show group details
+Create [--from <path>]      # Interactive builder, new group
+Edit <name>                 # Interactive builder, update existing
+Export <name> [path]        # Export config to TOML file
+Add <subcommand>
+  - Member <group> <agent> [--role] [--capabilities]
+  - Memory <group> <label> [--content | --path]  # shared memory
+  - Source <group> <source>                       # data source
+Remove <subcommand>
+  - Member <group> <agent>
+  - Memory <group> <label>
+  - Source <group> <source>
+```
+
+## Interactive Builder Flow
+
+### Entry Points
+
+- `agent create` → Start with `AgentConfig::default()`
+- `agent create --from ./agent.toml` → Load from file
+- `agent edit myagent` → Load from database by name
+
+### Main Loop
+
+```
+1. Load/initialize config
+2. Display sectioned summary
+3. Menu: "What would you like to change?"
+   - Basic Info (name, system_prompt, persona, instructions)
+   - Model (provider, model name, temperature)
+   - Memory Blocks
+   - Tools & Rules
+   - Context Options
+   - Integrations (bluesky_handle)
+   - [Done - Save]
+   - [Cancel]
+4. User selects section → enters section editor
+5. After edit, write state to ~/.cache/pattern/builder-state.toml
+6. Returns to step 2
+7. On "Done": Save menu (Database / File / Both / Preview)
+```
+
+### Group Builder Sections
+
+- Basic Info (name, description)
+- Pattern (supervisor/round-robin/pipeline/dynamic/sleeptime)
+- Members
+- Shared Memory
+- Data Sources
+- [Done - Save]
+- [Cancel]
+
+## Summary Display
+
+Sectioned display with truncation for long values:

+
+- Long text truncated with "..."
+- File paths shown as "(from file: path)"
+- Empty/default fields shown as "(none)" or "(default)"
+
+## Section Editors
+
+### Simple Text Fields
+
+```
+Current value: You are a helpful AI assistant...
+New value (@ to link file, empty to keep current):
+```
+
+### Enum Fields
+
+Arrow-key select via dialoguer:
+
+```
+Model provider:
+> anthropic
+  openai
+  gemini
+  ollama
+```
+
+### Tools List
+
+Multi-select with custom option:
+
+```
+Select tools (space to toggle, enter to confirm):
+  [x] block
+  [x] block_edit
+  [x] recall
+  [x] search
+  [x] send_message
+  [ ] source
+  [ ] web
+  [ ] calculator
+  [ ] file
+  ---
+  [ ] + Add custom tool...
+```
+
+### Collections (Memory Blocks, Tool Rules, Members)
+
+List with CRUD + TOML escape hatch:
+
+```
+Memory Blocks:
+  1. core_memory [read_write]
+  2. task_context [read_only]
+
+  [Add new]
+  [Edit as TOML]
+  [Done]
+```
+
+Select item to edit/remove, or add new with guided prompts.
+
+## Save Flow
+
+### Save Menu
+
+```
+Where to save?
+> Save to database
+  Export to file
+  Both
+  Preview (show TOML, don't save)
+  Cancel
+```
+
+### Behavior
+
+- **Database save (Create):** Generates new ID, inserts agent/group
+- **Database save (Edit):** Updates existing by ID
+- **File export:** Prompts for path, writes full TOML, preserves file paths
+- **Preview:** Pretty-prints TOML, returns to save menu
+
+### Error Handling
+
+- Validation before save (name required, model required)
+- On DB error: show error, offer to export to file instead
+- On file error: show error, return to save menu
+
+## Implementation Structure
+
+### File Organization
+
+```
+src/commands/
+  agent.rs          # AgentCommands enum, dispatch to handlers
+  group.rs          # GroupCommands enum, dispatch to handlers
+  builder/
+    mod.rs          # Shared builder infrastructure
+    agent.rs        # Agent-specific builder logic
+    group.rs        # Group-specific builder logic
+    display.rs      # Summary rendering (boxed display)
+    editors.rs      # Section editors (text, enum, collections)
+    save.rs         # Save flow (DB, file, preview)
+```
+
+### Key Types
+
+```rust
+/// Builder state machine
+struct ConfigBuilder<T> {
+    config: T,
+    source: ConfigSource,
+    modified: bool,
+}
+
+enum ConfigSource {
+    New,
+    FromFile(PathBuf),
+    FromDb(String),  // agent/group name
+}
+
+/// Trait for buildable configs
+trait InteractiveBuilder: Sized {
+    fn sections() -> Vec<Section>;
+    fn display_summary(&self) -> String;
+    fn edit_section(&mut self, section: &Section) -> Result<()>;
+    fn validate(&self) -> Result<()>;
+}
+```
+
+## Edge Cases
+
+### Name Conflicts
+
+- On Create: Check if name exists, prompt to choose different or switch to Edit
+- On Edit: Validate name changes against existing agents/groups
+
+### Interrupted Sessions
+
+- No auto-save/draft system
+- State written to `~/.cache/pattern/builder-state.toml` after each edit
+- User can recover with `--from` flag
+
+### Large Configs
+
+- TOML editor escape hatch for complex tool rules
+- File path approach for long system prompts
+
+### Group Member References
+
+- Members reference agents by name
+- Validate agent exists when adding
+- Consider orphan check on agent delete
+
+### Validation
+
+- Validate on save, not per-field
+- Show all errors at once, return to builder
+
+## Dependencies
+
+- `dialoguer` - Already in deps, used for interactive prompts
+- `owo_colors` - Already in deps, used for colored output
+- Pattern's existing TOML parsing via `pattern_core::config`

+# WASM Extension System Design
+
+**Status**: Future work - saved for later
+**Date**: 2025-12-29
+
+## Overview
+
+Design for a WASM-based plugin system for Pattern, enabling sandboxed extensions for data sources and tools. Based on Zed's extension API approach using wit-bindgen and the WebAssembly Component Model.

+## Config Integration
+
+```rust

+pub enum DataSourceConfig {
+    Bluesky(BlueskySourceConfig),
+    Discord(DiscordSourceConfig),
+    File(FileSourceConfig),
+    Wasm(WasmSourceConfig),       // WASM plugins
+    Custom(CustomSourceConfig),    // Native inventory plugins
+}
+
+#[derive(Debug, Clone, Serialize, Deserialize)]
+pub struct WasmSourceConfig {
+    pub name: String,
+    pub path: PathBuf,
+    pub source_kind: WasmSourceKind,

+#[serde(rename_all = "snake_case")]
+pub enum WasmSourceKind {
+    Stream,
+    Block,

+```
+
+Example config:
+```toml

+## Benefits
+
+| Aspect | Raw JSON/Memory | WIT + wit-bindgen |
+|--------|-----------------|-------------------|
+| Type safety | Runtime errors | Compile-time checks |
+| Serialization | Manual JSON | Automatic, efficient |
+| API evolution | Breaking changes | Versioned interfaces |
+| Documentation | Comments only | WIT is self-documenting |
+| Multi-language | Rust-only practical | Any WASM language |
+
+## Dependencies
+
+- `wasmtime` - WASM runtime with Component Model support
+- `wit-bindgen` - Code generation from WIT definitions
+- Possibly `wasi-http` for HTTP access in plugins
+
+## Open Questions
+
+1. How to handle async in WASM? (WASM is sync, may need spawn_blocking or async cooperation)
+2. Plugin discovery - scan directory for .wasm files?
+3. Hot reloading - watch for plugin changes?
+4. Sandboxing limits - memory, CPU, filesystem access?
+5. Plugin signing/verification for security?

+# CAR Export v3 Design
+
+## Overview
+
+New import/export system for pattern_core using CAR (Content Addressable aRchive) files. Replaces the v1/v2 format from SurrealDB era with a clean implementation matching the new SQLite-backed architecture.
+
+## Format Version
+
+- **Version 3** - Signals evolution from v1/v2, allows old readers to reject
+- v1/v2 files → use converter in pattern_surreal_compat
+- v3+ files → handled by pattern_core directly
+
+## Export Scopes
+
+1. **Agent** - Single agent with all its data
+2. **Group** - Group config + member agents (or thin: config only)
+3. **Constellation** - All agents and groups with deduplication
+
+## Root Structure
+
+```
+ExportManifest (CAR root block)
+├── version: 3
+├── exported_at: DateTime<Utc>
+├── export_type: Agent | Group | Constellation
+├── stats: ExportStats
+│   ├── agent_count, group_count
+│   ├── message_count, memory_block_count
+│   ├── archival_entry_count
+│   └── total_bytes
+└── data_cid: Cid → AgentExport | GroupExport | ConstellationExport
+```
+
+## Agent Export
+
+```
+AgentExport
+├── agent: AgentRecord (inline - small)
+│   ├── id, name, description
+│   ├── model_provider, model_name
+│   ├── system_prompt
+│   ├── config: serde_json::Value (full AgentConfig)
+│   ├── enabled_tools, tool_rules
+│   ├── status, created_at, updated_at
+├── message_chunk_cids: Vec<Cid>
+├── memory_block_cids: Vec<Cid>
+├── archival_entry_cids: Vec<Cid>
+└── archive_summary_cids: Vec<Cid>
+```
+
+## Memory Blocks
+
+Memory blocks use Loro CRDT snapshots which may exceed CAR block size limits.
+
+```
+MemoryBlockExport (head block)
+├── id, agent_id, label, description
+├── block_type, char_limit, permission, pinned
+├── content_preview: String (rendered text for inspection)
+├── metadata, is_active
+├── frontier, last_seq
+├── created_at, updated_at
+├── snapshot_cids: Vec<Cid>  // chunks if > 1MB
+└── total_snapshot_bytes: u64
+
+SnapshotChunk
+├── index: u32
+├── data: Vec<u8>
+└── next_cid: Option<Cid>  // optional for streaming
+```
+
+## Archival Entries
+
+Exported directly (text content, reasonable size):
+
+```
+ArchivalEntryExport
+├── id, agent_id, content
+├── metadata: Option<serde_json::Value>
+├── chunk_index, parent_entry_id
+└── created_at
+```
+
+## Messages
+
+Chunked by size with message count ceiling:
+
+```
+MessageChunk
+├── chunk_index: u32
+├── start_position: String  // Snowflake ID
+├── end_position: String
+├── messages: Vec<MessageRecord>
+│   ├── id, agent_id, position, batch_id, sequence_in_batch
+│   ├── role, content_json
+│   ├── batch_type, source, source_metadata
+│   ├── is_archived, is_deleted
+│   └── created_at
+└── message_count: u32
+```
+
+**Chunking strategy:**
+- Target ~900KB per chunk (headroom under 1MB limit)
+- Cap at 1000 messages per chunk
+- Size check before adding each message
+- Finalize chunk when either limit would be exceeded
+
+## Archive Summaries
+
+```
+ArchiveSummaryExport
+├── id, agent_id
+├── summary: String
+├── start_position, end_position
+├── message_count: i64
+├── previous_summary_id: Option<String>
+├── depth: i64
+└── created_at
+```
+
+## Group Export
+
+```
+GroupExport
+├── group: GroupRecord
+│   ├── id, name, description
+│   ├── pattern_type, pattern_config
+│   └── created_at, updated_at
+├── members: Vec<GroupMemberRecord>
+│   ├── agent_id, role, capabilities, joined_at
+├── agent_exports: Vec<AgentExport>  // inline for standalone
+└── shared_memory_cids: Vec<Cid>
+
+GroupConfigExport (thin variant)
+├── group: GroupRecord
+└── member_agent_ids: Vec<AgentId>
+```
+
+## Constellation Export
+
+Deduplicates agents across groups:
+
+```
+ConstellationExport
+├── version: 3
+├── owner_id: String
+├── exported_at: DateTime<Utc>
+├── agent_exports: HashMap<AgentId, Cid>  // shared pool
+├── group_exports: Vec<GroupExportThin>
+│   ├── group: GroupRecord
+│   ├── members: Vec<GroupMemberRecord>
+│   ├── agent_cids: Vec<Cid>  // references into pool
+│   └── shared_memory_cids: Vec<Cid>
+└── standalone_agent_cids: Vec<Cid>
+```
+
+## Export Options
+
+```rust
+pub struct ExportOptions {
+    pub target: ExportTarget,
+    pub include_messages: bool,
+    pub include_archival: bool,
+    pub max_chunk_bytes: usize,      // default 900_000
+    pub max_messages_per_chunk: usize, // default 1000
+}
+
+pub enum ExportTarget {
+    Agent(AgentId),
+    Group { id: GroupId, thin: bool },
+    Constellation,
+}
+```
+
+## Import Options
+
+```rust
+pub struct ImportOptions {
+    pub owner_id: UserId,
+    pub rename: Option<String>,
+    pub preserve_ids: bool,
+    pub include_messages: bool,
+    pub include_archival: bool,
+}
+```
+
+## Import Flow
+
+1. Read manifest, validate version == 3
+2. Load export data block
+3. For each agent:
+   - Insert Agent row
+   - Stream message chunks → insert
+   - Reconstruct Loro snapshots → insert memory blocks
+   - Insert archival entries
+   - Queue embedding regeneration
+4. For groups: insert group + members, link agents
+5. Return imported entity IDs
+
+## Converter (pattern_surreal_compat)
+
+Handles migration from old format:
+
+```
+Sources:
+├── Live SurrealDB connection
+└── v1/v2 CAR files
+
+Flow:
+1. Load old data (surreal query or CAR parse)
+2. Map old types → new pattern_db types
+3. Call pattern_core export functions
+4. Output v3 CAR file
+```
+
+## Implementation Location
+
+- **pattern_core**: New export/import module
+- **pattern_surreal_compat**: Converter using pattern_core
+
+## Encoding
+
+- DAG-CBOR for all blocks
+- CIDs: Blake3-256 + DAG-CBOR codec (0x71)
+- Max block size: 1MB (IPLD compatibility)
+
+## Notes
+
+- No embeddings stored - regenerate on import
+- Loro snapshots are full exports (not deltas)
+- Archive summaries included alongside original messages

+# CAR Export v3 Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Implement CAR v3 import/export for pattern_core and migration converter in pattern_surreal_compat.
+
+**Architecture:** New export module in pattern_core using existing CAR dependencies (iroh-car, serde_ipld_dagcbor, cid). Types mirror pattern_db models. Converter in pattern_surreal_compat maps old types to new then calls pattern_core export.
+
+**Tech Stack:** Rust, iroh-car, serde_ipld_dagcbor, cid, multihash, pattern_db (sqlx/SQLite)
+
+---
+
+## Task 1: Export Types Module
+
+**Files:**
+- Create: `crates/pattern_core/src/export/mod.rs`
+- Create: `crates/pattern_core/src/export/types.rs`
+- Modify: `crates/pattern_core/src/lib.rs` (add export module)
+
+**Step 1: Create the export module structure**
+
+Create `crates/pattern_core/src/export/mod.rs`:
+
+```rust
+//! CAR archive export/import for Pattern agents and constellations.
+//!
+//! Format version 3 - designed for SQLite-backed architecture.
+
+mod types;
+mod exporter;
+mod importer;
+
+pub use types::*;
+pub use exporter::*;
+pub use importer::*;
+
+/// Export format version
+pub const EXPORT_VERSION: u32 = 3;
+
+/// Maximum bytes per CAR block (IPLD compatibility)
+pub const MAX_BLOCK_BYTES: usize = 1_000_000;
+
+/// Default max messages per chunk
+pub const DEFAULT_MAX_MESSAGES_PER_CHUNK: usize = 1000;
+
+/// Target bytes per chunk (leave headroom under MAX_BLOCK_BYTES)
+pub const TARGET_CHUNK_BYTES: usize = 900_000;
+```
+
+**Step 2: Create export types**
+
+Create `crates/pattern_core/src/export/types.rs`:
+
+```rust
+//! Types for CAR v3 export/import.
+
+use chrono::{DateTime, Utc};
+use cid::Cid;
+use serde::{Deserialize, Serialize};

+## Task 2: CAR Utilities Module
+
+**Files:**
+- Create: `crates/pattern_core/src/export/car.rs`

+
+**Step 3: Add ExportError to error.rs**

+
+Check if `queries::get_agent`, `queries::get_memory_blocks`, `queries::get_messages`, `queries::get_archival_entries`, `queries::get_archive_summaries` exist in pattern_db. If not, we'll need to add them in Task 4.
+
+**Step 3: Verify compilation**
+
+Run: `cargo check -p pattern-core --features export`
+
+Note: This will likely fail due to missing query functions. That's expected - we'll add them in Task 4.
+
+**Step 4: Commit (even if incomplete)**
+
+```bash
+git add crates/pattern_core/src/export/exporter.rs
+git commit -m "feat(export): add agent exporter (WIP)
+
+- Exporter struct with export_agent method
+- Memory block export with Loro snapshot chunking
+- Message export with size-based chunking
+- Archival entry and archive summary export
+- BlockCollector for CAR writing
+

+
+## Task 4: Add Missing Query Functions to pattern_db
+
+**Files:**
+- Modify: `crates/pattern_db/src/queries/agent.rs`
+- Modify: `crates/pattern_db/src/queries/memory.rs`
+- Modify: `crates/pattern_db/src/queries/message.rs`
+
+Review existing query functions and add any missing ones needed by the exporter:
+- `get_agent(pool, agent_id) -> Option<Agent>`
+- `get_memory_blocks(pool, agent_id) -> Vec<MemoryBlock>`
+- `get_messages(pool, agent_id, since: Option<DateTime>) -> Vec<Message>`
+- `get_archival_entries(pool, agent_id) -> Vec<ArchivalEntry>`
+- `get_archive_summaries(pool, agent_id) -> Vec<ArchiveSummary>`
+
+**Step 1: Check existing queries**
+
+Read each query module to see what exists.
+
+**Step 2: Add missing functions**
+
+Add any missing query functions using sqlx macros.
+
+**Step 3: Run sqlx prepare**
+
+```bash
+cd crates/pattern_db
+sqlx prepare
+```
+
+**Step 4: Verify compilation**
+
+```bash
+cargo check -p pattern-db
+cargo check -p pattern-core --features export
+```
+
+**Step 5: Commit**
+
+```bash
+git add crates/pattern_db/
+git commit -m "feat(db): add export query functions
+
+- get_agent, get_memory_blocks, get_messages
+- get_archival_entries, get_archive_summaries

+# MemoryStore API cleanup
+
+**Date**: 2026-01-01
+**Status**: Design
+**Authors**: Human + Claude
+**Related**: [Persistent undo design](./2026-01-01-persistent-undo-design.md) (benefits from this cleanup but doesn't depend on it)
+
+## Summary
+
+Clean up the MemoryStore API by embedding block metadata in StructuredDocument, changing return types, and deprecating convenience methods that obscure the get→mutate→persist pattern.
+
+## Motivation
+
+The current API has several pain points that make code awkward and inefficient:
+
+### Problem 1: Metadata/document split causes double DB hits
+
+`get_block()` returns `Option<StructuredDocument>` and `get_block_metadata()` returns `Option<BlockMetadata>`. Many callsites need both:
+
+```rust
+// Current pattern - two round trips
+let metadata = memory.get_block_metadata(agent_id, label).await?;
+let doc = memory.get_block(agent_id, label).await?;
+```
+
+### Problem 2: create_block returns ID, but you usually want the document
+
+```rust
+// Current pattern - create then immediately fetch
+let block_id = memory.create_block(agent_id, label, desc, block_type, schema, limit).await?;
+let doc = memory.get_block(agent_id, label).await?.unwrap();
+doc.set_text("initial content", true)?;
+memory.persist_block(agent_id, label).await?;
+```
+
+### Problem 3: Convenience methods obscure the data flow
+
+`update_block_text`, `append_to_block`, `replace_in_block` exist for convenience but:
+- Hide the get→mutate→persist pattern
+- Don't compose well with StructuredDocument's richer operations
+- Make features like checkpointing awkward to integrate
+
+## Design
+
+### Embed metadata in StructuredDocument
+
+Currently StructuredDocument has:
+```rust
+pub struct StructuredDocument {
+    doc: LoroDoc,
+    schema: BlockSchema,
+    permission: MemoryPermission,
+    label: String,
+    accessor_agent_id: Option<String>,
+}
+```
+
+Expand to include full block metadata:
+```rust
+pub struct StructuredDocument {
+    doc: LoroDoc,
+
+    // Schema and permission (already present)
+    schema: BlockSchema,
+    permission: MemoryPermission,
+
+    // Block identity (partially present)
+    label: String,
+    accessor_agent_id: Option<String>,
+
+    // NEW: Full metadata
+    id: String,
+    agent_id: String,
+    description: String,
+    block_type: BlockType,
+    char_limit: usize,
+    pinned: bool,
+    created_at: DateTime<Utc>,
+    updated_at: DateTime<Utc>,
+}
+```
+
+Add accessors:
+```rust
+impl StructuredDocument {
+    /// Get block metadata as a struct (clones string fields)
+    pub fn metadata(&self) -> BlockMetadata {
+        BlockMetadata {
+            id: self.id.clone(),
+            agent_id: self.agent_id.clone(),
+            label: self.label.clone(),
+            description: self.description.clone(),
+            block_type: self.block_type,
+            schema: self.schema.clone(),
+            char_limit: self.char_limit,
+            permission: self.permission,
+            pinned: self.pinned,
+            created_at: self.created_at,
+            updated_at: self.updated_at,
+        }
+    }
+
+    // Direct accessors (no allocation)
+    pub fn id(&self) -> &str { &self.id }
+    pub fn agent_id(&self) -> &str { &self.agent_id }
+    pub fn description(&self) -> &str { &self.description }
+    pub fn block_type(&self) -> BlockType { self.block_type }
+    pub fn char_limit(&self) -> usize { self.char_limit }
+    pub fn is_pinned(&self) -> bool { self.pinned }
+}
+```
+
+### Update MemoryStore signatures
+
+```rust
+#[async_trait]
+pub trait MemoryStore: Send + Sync + fmt::Debug {
+    /// Create a new memory block, returning the document ready for editing.
+    /// The returned document includes all metadata.
+    async fn create_block(
+        &self,
+        agent_id: &str,
+        label: &str,
+        description: &str,
+        block_type: BlockType,
+        schema: BlockSchema,
+        char_limit: usize,
+    ) -> MemoryResult<StructuredDocument>;  // Was: MemoryResult<String>
+
+    /// Get a block's document (includes all metadata).
+    async fn get_block(
+        &self,
+        agent_id: &str,
+        label: &str,
+    ) -> MemoryResult<Option<StructuredDocument>>;  // Unchanged signature, but doc now has metadata
+
+    /// Get block metadata without loading the Loro document.
+    /// Useful for listing/filtering when you don't need the content.
+    async fn get_block_metadata(
+        &self,
+        agent_id: &str,
+        label: &str,
+    ) -> MemoryResult<Option<BlockMetadata>>;  // Keep for lightweight queries
+
+    // ... other methods unchanged ...
+}
+```
+
+### Deprecate convenience methods
+
+```rust
+// In MemoryStore trait:
+
+#[deprecated(
+    since = "0.x.0",
+    note = "Use get_block() then doc.set_text() then persist_block()"
+)]
+async fn update_block_text(
+    &self,
+    agent_id: &str,
+    label: &str,
+    new_content: &str,
+) -> MemoryResult<()>;
+
+#[deprecated(
+    since = "0.x.0",
+    note = "Use get_block() then doc.append_text() then persist_block()"
+)]
+async fn append_to_block(
+    &self,
+    agent_id: &str,
+    label: &str,
+    content: &str,
+) -> MemoryResult<()>;
+
+#[deprecated(
+    since = "0.x.0",
+    note = "Use get_block() then doc.replace_text() then persist_block()"
+)]
+async fn replace_in_block(
+    &self,
+    agent_id: &str,
+    label: &str,
+    old: &str,
+    new: &str,
+) -> MemoryResult<bool>;
+```
+
+Keep them working during transition, remove in a later release.
+
+### CachedBlock simplification
+
+With metadata in StructuredDocument, CachedBlock becomes a cache-tracking wrapper:
+
+```rust
+pub struct CachedBlock {
+    /// The document with embedded metadata
+    pub doc: StructuredDocument,
+
+    /// Cache management state
+    pub last_seq: i64,
+    pub last_persisted_frontier: Option<VersionVector>,
+    pub dirty: bool,
+    pub last_accessed: DateTime<Utc>,
+
+    /// For checkpoint throttling (see persistent-undo-design.md)
+    pub last_checkpoint_at: Option<Instant>,
+}
+```
+
+The duplicated metadata fields (`id`, `agent_id`, `label`, etc.) can be removed - access via `doc.id()`, `doc.agent_id()`, etc.
+
+## Callsites to update
+
+Based on grep, ~30+ locations use the convenience methods or need signature updates:
+
+**CLI** (`pattern_cli/src/commands/`):
+- `debug.rs:689` - `update_block_text`
+- `builder/group.rs:1086,1088` - `update_block_text`
+- `builder/agent.rs:996` - `update_block_text`
+
+**Tools** (`pattern_core/src/tool/builtin/`):
+- `block_edit.rs` - tests use `update_block_text` extensively
+- `block.rs:776` - `update_block_text`
+- `file.rs:455,778,1050,1246,1296` - all three convenience methods
+
+**Data sources** (`pattern_core/src/data_source/`):
+- `file_source.rs:955,1182,1201,1319,1842,1896` - `update_block_text`
+- `helpers.rs:139` - `update_block_text`
+
+**Runtime/context** (`pattern_core/src/runtime/`, `context/`):
+- Various delegate implementations that just forward calls
+
+**Tests throughout**
+
+## Implementation plan
+
+### Step 1: Expand StructuredDocument
+1. Add new fields to struct
+2. Add `metadata()` and accessor methods
+3. Update all constructors (`new`, `new_with_identity`, `new_with_permission`, `from_snapshot`, etc.)
+4. Ensure Clone still works correctly (LoroDoc is Arc-shared)
+
+### Step 2: Update MemoryCache
+1. Modify `load_from_db` to populate metadata in returned doc
+2. Change `create_block` impl to return `StructuredDocument`
+3. Simplify CachedBlock (remove duplicated fields, access via doc)
+4. Update cache hit path in `get()` to ensure metadata is current
+
+### Step 3: Update MemoryStore trait
+1. Change `create_block` signature
+2. Add `#[deprecated]` to convenience methods
+3. Update trait implementations (MemoryCache, any mocks)
+
+### Step 4: Update callsites
+1. Fix all `create_block` callsites (now returns doc, not ID)
+2. Migrate convenience method calls to get→mutate→persist pattern
+3. Remove double-fetch patterns where both metadata and doc were fetched
+4. Update tests
+
+### Step 5: Cleanup
+1. Remove deprecated method implementations (later release)
+2. Remove unused CachedBlock fields
+3. Update documentation
+
+## Future: Auto-persistence
+
+The explicit `persist_block()` call is easy to forget. Future options:
+
+**Periodic flush:**
+```rust
+impl MemoryCache {
+    /// Persist all dirty blocks
+    pub async fn flush_dirty(&self) -> MemoryResult<()>;
+
+    /// Start background task that flushes periodically
+    pub async fn start_auto_flush(&self, interval: Duration);
+}
+```
+
+**RAII guard:**
+```rust
+// Persist automatically when guard drops
+let mut block = memory.get_block_mut(agent_id, label).await?;
+block.set_text("new content", false)?;
+// persist on drop
+```
+
+This is out of scope for this cleanup but worth considering.
+
+## Testing
+
+- Ensure all existing tests pass after migration
+- Add tests for new accessors
+- Verify no performance regression from metadata in every doc

+# Persistent undo for Loro-backed memory blocks
+
+**Date**: 2026-01-01
+**Status**: Design
+**Authors**: Human + Claude
+
+## Summary
+
+Add persistent undo capability to Pattern's CRDT-based memory system. Leverage Loro's versioning primitives (`VersionVector`, `fork_at`) to enable agents and users to revert block edits that survive process restarts.
+
+## Background
+
+Pattern uses [Loro](https://loro.dev/) CRDTs for memory blocks via `StructuredDocument`. Currently we track `last_persisted_frontier` for delta exports but don't expose any undo/time-travel features to agents or tools. The design doc from 2025-12-27 mentioned `UndoManager` integration but it was never implemented.
+
+### Current architecture
+
+- **StructuredDocument** (`memory/document.rs`): Wraps `LoroDoc` with schema-aware operations (Text, Map, List, Log, Composite). Handles permissions. No undo support.
+- **MemoryCache** (`memory/cache.rs`): Stores `CachedBlock` instances, loads from DB with snapshot + deltas, persists changes. Tracks `last_persisted_frontier: Option<VersionVector>`.
+- **FileSource** (`data_source/file_source.rs`): Manages local files as Loro-backed blocks. Maintains `disk_doc` (fork) and `memory_doc` (clone), tracks `last_saved_frontier`.
+- **BlockEditTool** (`tool/builtin/block_edit.rs`): Agent-facing tool for edits (append, replace, patch, set_field, edit_range). No undo.
+
+## Options considered
+
+### Option A: Loro UndoManager (session-only)
+
+Loro provides `UndoManager` for per-peer undo/redo:
+
+```rust
+let undo = UndoManager::new(&doc);
+doc.get_text("content").insert(0, "hello")?;
+doc.commit();
+undo.undo();  // Reverts the insert
+```
+
+**Pros:**
+- Simple API, works out of the box
+- Merge interval for batching rapid edits
+- `group_start()`/`group_end()` for explicit grouping
+
+**Cons:**
+- **In-memory only** - doesn't survive process restarts
+- Per-peer scoped (fine for us since agents own their blocks)
+- Would need to create/store managers per block
+
+**Verdict:** Rejected as primary solution. Could be used alongside persistent undo for quick session-based undo, but we need persistence.
+
+### Option B: Time travel with checkout
+
+Loro's `checkout(&frontiers)` rewinds document state:
+
+```rust
+let old_frontiers = doc.state_frontiers();
+// ... make edits ...
+doc.checkout(&old_frontiers);  // Document now read-only at old state
+doc.attach();  // Return to latest
+```
+
+**Pros:**
+- Can view any historical state
+- Precise control over versions
+
+**Cons:**
+- Document becomes detached (read-only) after checkout
+- Need `set_detached_editing(true)` to allow edits at historical points
+- Doesn't cleanly support "undo and continue editing from there"
+
+**Verdict:** Useful for viewing history but not ideal for undo workflow.
+
+### Option C: Fork-based restore (selected)
+
+Use `fork_at(&frontiers)` to create a new document at a historical state:
+
+```rust
+let checkpoint_vv = VersionVector::decode(&stored_bytes)?;
+let frontiers = doc.vv_to_frontiers(&checkpoint_vv);
+let restored = doc.fork_at(&frontiers);  // New doc at old state, ready for editing
+```
+
+**Pros:**
+- Clean mental model: undo creates fresh doc at old state
+- New doc is immediately editable (no detached mode)
+- VersionVector is serializable (`encode()`/`decode()`) for persistence
+- Discards operations after checkpoint (true undo, not just viewing)
+
+**Cons:**
+- Loses history after checkpoint (by design for undo)
+- Need to manage checkpoint storage
+
+**Verdict:** Selected. Clean, persistent, matches undo semantics.
+
+### Option D: Hybrid (UndoManager + checkpoints)
+
+Combine session-based UndoManager for quick undo with persisted checkpoints for named save points.
+
+**Verdict:** Could layer this on later. Start with Option C.
+
+## Design
+
+### Existing infrastructure
+
+Most of the infrastructure for undo already exists in `pattern_db`:
+
+- **`MemoryBlockUpdate`**: Stores incremental Loro deltas with `seq` ordering
+- **`MemoryBlockCheckpoint`**: Stores full Loro snapshots (for consolidation, not currently used)
+- **`get_checkpoint_and_updates()`**: Loads checkpoint + replays deltas to reconstruct state
+
+Currently, consolidation (`consolidate_checkpoint()`) is implemented but **not wired up**—updates accumulate indefinitely. This means we already have full edit history; we just need to expose it for undo.
+
+### Required changes
+
+**1. Add version vector to updates**
+
+Add `frontier: Option<Vec<u8>>` to `MemoryBlockUpdate` to store the version vector after each update:
+
+```sql
+ALTER TABLE memory_block_updates ADD COLUMN frontier BLOB;
+```
+
+```rust
+// In store_update():
+pub async fn store_update(
+    pool: &SqlitePool,
+    block_id: &str,
+    update_blob: &[u8],
+    frontier: Option<&[u8]>,  // NEW: version vector after this update
+    source: Option<&str>,
+) -> Result<i64, DbError>;
+```
+
+**2. Undo = replay to previous seq**
+
+To undo to before update N:
+1. Load latest checkpoint (if any)
+2. Replay updates with `seq < N`
+3. Use `fork_at()` to get clean doc at that state
+
+```rust
+// Undo implementation:
+async fn undo_block(&self, agent_id: &str, label: &str) -> MemoryResult<bool> {
+    let block_id = self.get_block_id(agent_id, label).await?
+        .ok_or_else(|| MemoryError::not_found(agent_id, label))?;
+
+    // Get the update we want to revert (most recent)
+    let latest_update = pattern_db::queries::get_latest_update(
+        self.dbs.constellation.pool(),
+        &block_id,
+    ).await?;
+
+    let target_seq = match latest_update {
+        Some(u) if u.seq > 0 => u.seq - 1,
+        _ => return Ok(false), // Nothing to undo
+    };
+
+    // Load checkpoint + updates up to target_seq
+    let (checkpoint, updates) = pattern_db::queries::get_checkpoint_and_updates_until(
+        self.dbs.constellation.pool(),
+        &block_id,
+        target_seq,
+    ).await?;
+
+    // Reconstruct doc at target state
+    let doc = reconstruct_doc_at(checkpoint, updates)?;
+    let frontier = doc.current_version();
+
+    // Fork to get clean doc (discards ops after target)
+    let restored = doc.inner().fork_at(&doc.inner().oplog_frontiers());
+
+    // Update cache and persist
+    // ... (update CachedBlock, mark dirty, persist)
+
+    Ok(true)
+}
+```
+
+**3. New queries**
+
+```rust
+/// Get the most recent update for a block
+pub async fn get_latest_update(
+    pool: &SqlitePool,
+    block_id: &str,
+) -> Result<Option<MemoryBlockUpdate>, DbError>;
+
+/// Get checkpoint + updates up to (inclusive) a seq number
+pub async fn get_checkpoint_and_updates_until(
+    pool: &SqlitePool,
+    block_id: &str,
+    max_seq: i64,
+) -> Result<(Option<MemoryBlockCheckpoint>, Vec<MemoryBlockUpdate>), DbError>;
+
+/// Delete updates after a seq number (for committing undo)
+pub async fn delete_updates_after(
+    pool: &SqlitePool,
+    block_id: &str,
+    after_seq: i64,
+) -> Result<u64, DbError>;
+```
+
+### MemoryStore trait additions
+
+```rust
+#[async_trait]
+pub trait MemoryStore: Send + Sync + fmt::Debug {
+    // ... existing methods ...
+
+    /// Undo the last persisted change to a block.
+    /// Returns true if undo was performed, false if no history available.
+    async fn undo_block(&self, agent_id: &str, label: &str) -> MemoryResult<bool>;
+
+    /// Get number of available undo steps for a block.
+    async fn undo_depth(&self, agent_id: &str, label: &str) -> MemoryResult<usize>;
+}
+```
+
+### Undo window and consolidation
+
+Currently: unlimited undo (no consolidation running).
+
+When consolidation is added, it should preserve recent updates for undo:
+
+```rust
+pub struct ConsolidationConfig {
+    /// Keep at least this many recent updates for undo
+    pub keep_recent_updates: usize,  // e.g., 50
+
+    /// Keep updates from at least this long ago
+    pub keep_recent_duration: Duration,  // e.g., 7 days
+
+    /// Consolidate when update count exceeds this
+    pub consolidate_threshold: usize,  // e.g., 100
+}
+```
+
+Consolidation would then:
+1. Create new checkpoint with merged state
+2. Delete updates older than `max(keep_recent_updates, keep_recent_duration)`
+3. Preserve recent updates for undo capability
+
+### Tool: block_undo
+
+Either add `undo` operation to BlockEditTool or create a new tool:
+
+```rust
+#[derive(Debug, Clone, Serialize, Deserialize, JsonSchema)]
+pub struct BlockUndoInput {
+    /// Label of the block to undo
+    pub label: String,
+}
+
+pub struct BlockUndoTool {
+    ctx: Arc<dyn ToolContext>,
+}
+
+#[async_trait]
+impl AiTool for BlockUndoTool {
+    type Input = BlockUndoInput;
+    type Output = ToolOutput;
+
+    fn name(&self) -> &str { "block_undo" }
+
+    fn description(&self) -> &str {
+        "Undo the last change to a memory block, restoring it to its previous state."
+    }
+
+    async fn execute(&self, input: Self::Input, _meta: &ExecutionMeta) -> Result<Self::Output> {
+        let memory = self.ctx.memory();
+        let agent_id = self.ctx.agent_id();
+
+        let undone = memory.undo_block(agent_id, &input.label).await?;
+
+        if undone {
+            Ok(ToolOutput::success(format!(
+                "Undid last change to block '{}'",
+                input.label
+            )))
+        } else {
+            Err(CoreError::tool_exec_msg(
+                "block_undo",
+                json!({"label": input.label}),
+                "No undo history available for this block",
+            ))
+        }
+    }
+}
+```
+
+### FileSource considerations
+
+For file-backed blocks, undo is more complex:
+
+1. **Memory side**: Restore memory_doc via `fork_at` (same as regular blocks)
+2. **Disk side**: Do NOT automatically revert disk file
+   - External editors may have modified the file
+   - User should explicitly save to disk if they want to propagate the undo
+
+After undo, file block would be in "memory ahead of disk" state. User/agent can:
+- Call save to write reverted content to disk
+- Or discard memory changes and reload from disk
+
+This matches the existing conflict model.
+
+## Related: MemoryStore API cleanup
+
+This undo work is related to but separate from a broader API cleanup effort. See [memory-api-cleanup.md](./2026-01-01-memory-api-cleanup.md) for details on:
+
+- Embedding full block metadata in StructuredDocument
+- Changing `create_block` to return the document (not just ID)
+- Deprecating convenience methods (`update_block_text`, `append_to_block`, `replace_in_block`)
+- Pushing callers toward get→mutate→persist pattern
+
+The API cleanup benefits the undo implementation (cleaner document access, simpler CachedBlock) but isn't a strict prerequisite. These can be done in parallel or sequenced either way.
+
+## Implementation plan
+
+### Phase 1: Database schema + queries
+1. Add migration: `ALTER TABLE memory_block_updates ADD COLUMN frontier BLOB`
+2. Update `store_update()` to accept and store frontier
+3. Implement `get_latest_update()`, `get_checkpoint_and_updates_until()`, `delete_updates_after()`
+4. Run `cargo sqlx prepare` in pattern_db
+
+### Phase 2: MemoryCache undo integration
+1. Update `persist()` to pass frontier to `store_update()`
+2. Implement `undo_block()` - replay to previous seq, fork, persist
+3. Implement `undo_depth()` - count of available updates
+4. Add to `MemoryStore` trait
+
+### Phase 3: Tool + testing
+1. Create `BlockUndoTool` (or add `undo` operation to BlockEditTool)
+2. Register in tool registry
+3. Add integration tests for undo scenarios
+4. Test edge cases: empty block, no history, rapid edits, undo multiple times
+
+### Phase 4: FileSource integration
+1. Ensure file blocks store updates like regular blocks
+2. Document the memory-vs-disk behavior after undo
+3. Consider adding explicit "revert to disk" operation
+
+### Future: Consolidation with undo preservation
+1. Wire up `consolidate_checkpoint()` with configurable retention
+2. Add `ConsolidationConfig` to `MemoryCache`
+3. Background task or on-persist trigger for consolidation
+4. Respect `keep_recent_updates` / `keep_recent_duration` for undo window
+
+## Auto-persist design
+
+### Motivation
+
+The current API requires callers to:
+1. Get a `StructuredDocument` from `MemoryStore`
+2. Mutate the document
+3. Call `memory.mark_dirty(agent_id, label)`
+4. Call `memory.persist_block(agent_id, label)`
+
+This is error-prone—callers can forget to mark dirty or persist, leading to data loss. Since `LoroDoc` is Arc-shared internally, mutations to the returned document already propagate back to the cached version. We can leverage Loro's subscription system to detect edits and auto-persist.
+
+### Design: subscription-based auto-persist
+
+When a block is loaded, we subscribe to the underlying `LoroDoc`. When changes are detected (via the subscription callback), we spawn a debounced persist operation.
+
+```

+
+        first_signal_at = None;
+    }
+}
+```
+
+### Subscription lifecycle
+
+1. **On load**: `setup_auto_persist()` creates subscription and debounce task
+2. **On edit + commit**: Subscription fires, signals debounce task
+3. **On debounce timeout**: Task calls `persist()`
+4. **On eviction**: Dropping `CachedBlock` drops `subscription` (unsubscribes) and aborts `persist_task`
+
+Important: Loro subscriptions only fire on `commit()`. Callers must call `doc.commit()` after edits for auto-persist to work. This is already the expected pattern for CRDT semantics.
+
+### Commit convenience
+
+To make auto-persist transparent, mutation methods on `StructuredDocument` could auto-commit:
+
+```rust
+impl StructuredDocument {
+    /// Set text content and commit (triggers subscriptions).
+    pub fn set_text_and_commit(&self, content: &str, is_system: bool) -> Result<(), DocumentError> {
+        self.set_text(content, is_system)?;
+        self.commit();
+        Ok(())
+    }
+
+    // Similar for append_text_and_commit, set_field_and_commit, etc.
+}
+```
+
+Or provide a guard pattern:
+
+```rust
+impl StructuredDocument {
+    /// Create an auto-committing scope.
+    /// Commit is called when the guard is dropped.
+    pub fn editing(&self) -> EditGuard<'_> {
+        EditGuard { doc: self }
+    }
+}
+
+pub struct EditGuard<'a> {
+    doc: &'a StructuredDocument,
+}
+
+impl Drop for EditGuard<'_> {
+    fn drop(&mut self) {
+        self.doc.commit();
+    }
+}
+
+// Usage:
+{
+    let _guard = doc.editing();
+    doc.set_text("hello", true)?;
+    doc.append_text(" world", true)?;
+} // commit() called here, triggers subscription → auto-persist
+```
+
+### Explicit persist still supported
+
+Auto-persist is fire-and-forget. For operations that need guaranteed persistence (e.g., before responding to user), callers can still call:
+
+```rust
+memory.persist_block(agent_id, label).await?;
+```
+
+This immediately persists, canceling any pending debounce.
+
+### Thread safety considerations
+
+- `LoroDoc` is internally thread-safe (uses Arc)
+- Subscription callbacks run synchronously in the thread that calls `commit()`
+- `mpsc::Sender::try_send` is non-blocking and safe from any thread
+- The debounce task runs on the Tokio runtime
+- `MemoryCache` uses `DashMap` for concurrent access
+
+### MemoryCache self-reference
+
+The debounce task needs to call `cache.persist()`, but `MemoryCache` isn't currently `Clone`. Options:
+
+1. **Arc\<MemoryCacheInner\>**: Wrap fields in inner struct, make `Clone` cheap. Cleanest approach since `persist()` has non-trivial logic.
+
+2. **Pass components directly**: Give the task `Arc<DashMap>` + `Arc<ConstellationDatabases>`, refactor persist logic into a free function. More churn but better testability.
+
+3. **Weak reference**: Task holds `Weak<MemoryCache>`, upgrades when needed. Gracefully handles cache being dropped, but adds upgrade ceremony on every persist.
+
+**Recommendation**: Option 1 (Arc\<Inner\>). Standard pattern, minimal API change, keeps persist logic encapsulated.
+
+Note: Even if the debounce task somehow outlives the cache, the mpsc channel closes when `CachedBlock` is dropped (which holds the `Sender`), causing the task to exit cleanly via `rx.recv() -> None`.
+
+### Integration with checkpoints (undo)
+
+Auto-persist integrates naturally with checkpoints:
+1. Edit detected → subscription fires → signals debounce
+2. Debounce timeout → `persist()` called
+3. In `persist()`: check if checkpoint is needed (time threshold)
+4. If yes: store checkpoint with previous version
+5. Export and store delta
+6. Update `last_persisted_frontier`
+
+No changes needed to checkpoint logic—it already runs in `persist()`.
+
+### Disabling auto-persist
+
+For specific blocks (e.g., high-frequency scratch buffers):
+
+```rust
+impl MemoryStore {
+    /// Get a block without setting up auto-persist.
+    /// Caller must manually persist changes.
+    async fn get_block_manual_persist(
+        &self,
+        agent_id: &str,
+        label: &str,
+    ) -> MemoryResult<Option<StructuredDocument>>;
+}
+```
+
+Or via block metadata:
+
+```rust
+// In BlockMetadata
+pub auto_persist: bool,  // defaults to true
+```
+
+### Implementation phases
+
+This feature slots into the existing implementation plan:
+
+#### Phase 2.5: Auto-persist infrastructure
+1. Add `AutoPersistConfig` to `MemoryCache`
+2. Add subscription/task fields to `CachedBlock`
+3. Implement `setup_auto_persist()` and `debounce_persist_loop()`
+4. Wire into `load_from_db()` to setup auto-persist on load
+5. Clean up subscription/task on cache eviction
+
+#### Phase 2.6: Commit convenience
+1. Add `EditGuard` pattern to `StructuredDocument`
+2. Update tool implementations to use guard or explicit commit
+3. Document the commit requirement in API docs
+
+## Open questions
+
+1. **Checkpoint threshold**: 30 seconds seems reasonable. Make configurable?
+
+2. **Redo support**: Not in initial design. Could add by keeping popped checkpoints in a "redo stack" until next edit clears it.
+
+3. **Checkpoint metadata**: Currently just storing operation name. Could store more context (agent_id, tool call ID, etc.) for audit trails.
+
+4. **Garbage collection**: Checkpoints accumulate forever. Add periodic cleanup of very old checkpoints? Age-based or count-based limit per block?
+
+5. **Auto-persist debounce tuning**: 500ms default feels right for interactive use. May need adjustment for batch operations. Should this be per-block configurable?
+
+6. **Commit ergonomics**: Should mutation methods auto-commit by default? This changes the current behavior where batched edits are possible. The `EditGuard` pattern preserves batching while ensuring commit happens.

+# Processing loop refactor
+
+## Summary
+
+Refactor the `DatabaseAgent::process()` loop to:
+1. Execute tools inline as content blocks are processed (not batched at end)
+2. Eliminate duplicated code via extracted helpers
+3. Port robust retry logic from old main branch
+4. Enable proper event ordering and early exit
+
+## Problem
+
+The current loop in `db_agent.rs` (~800 lines) has several issues:
+
+1. **Tool extraction duplicated** - Same logic appears twice: once for streaming events, again for execution
+2. **Error handling repeated** - The `send_event(Error) → set_state(Error) → recovery → set_state(Ready)` pattern appears 5+ times
+3. **Force-execution duplicated** - Start constraints and exit requirements have nearly identical ~50-line blocks
+4. **Tools execute after full response** - Collects all tool calls, then executes. Prevents early exit and proper ordering
+5. **Missing retry robustness** - Old version had Gemini quirk handling, rate limit parsing, exponential backoff
+
+## Solution
+
+### New module structure
+
+```
+crates/pattern_core/src/agent/
+├── mod.rs
+├── db_agent.rs              # Slimmed: struct, builder, Agent trait

+```
+
+### Core types
+
+#### Parameter structs (not objects with methods)
+
+```rust
+/// Immutable context for the processing loop
+pub struct ProcessingContext<'a> {
+    pub agent_id: &'a AgentId,
+    pub runtime: &'a AgentRuntime,
+    pub model: &'a dyn ModelProvider,
+    pub response_options: &'a ResponseOptions,
+    pub base_instructions: Option<&'a str>,
+    pub batch_id: SnowflakePosition,
+    pub batch_type: BatchType,
+}
+
+/// Mutable state that changes during processing
+pub struct ProcessingState {
+    pub process_state: ProcessState,
+    pub sequence_num: u32,
+    pub start_constraint_attempts: u8,
+    pub exit_requirement_attempts: u8,
+}
+```
+
+#### Content iteration (unify without normalizing)
+
+```rust
+/// Unified view for iteration - doesn't transform underlying data
+pub enum ContentItem<'a> {
+    Text(&'a str),
+    Thinking(&'a str),
+    ToolUse {
+        id: &'a str,
+        name: &'a str,
+        input: &'a serde_json::Value,
+    },
+    Other,
+}
+
+/// Iterator adapter over MessageContent variants
+pub fn iter_content_items(content: &[MessageContent]) -> impl Iterator<Item = ContentItem<'_>>
+```
+
+Handles both `MessageContent::ToolCalls(vec)` and `MessageContent::Blocks` with `ContentBlock::ToolUse` without transforming storage format.
+
+#### Loop outcome
+
+`ToolAction` (defined in runtime) is used directly in the processing loop - no separate `BlockAction` needed.
+
+```rust
+pub enum LoopOutcome {
+    Completed { metadata: ResponseMetadata },
+    HeartbeatRequested {
+        tool_name: String,
+        call_id: String,
+        next_sequence_num: u32,
+    },
+    ErrorRecovered,
+}
+```
+
+### Retry logic (ported from old version)
+
+```rust
+pub struct RetryConfig {
+    pub max_attempts: u8,        // Default: 10
+    pub base_backoff_ms: u64,    // Default: 1000
+    pub max_backoff_ms: u64,     // Default: 60_000
+    pub jitter_ms: u64,          // Default: 2000
+}
+
+pub enum RetryDecision {
+    Retry { wait_ms: u64, modify_prompt: Option<PromptModification> },
+    Fatal(ProcessingError),
+}
+
+pub enum PromptModification {
+    /// Gemini empty candidates quirk - append punctuation
+    AppendToLastMessage(String),
+}
+
+pub async fn complete_with_retry(
+    ctx: &ProcessingContext<'_>,
+    request: &mut Request,
+    config: &RetryConfig,
+) -> Result<Response, ProcessingError>
+```
+
+Error classification handles:
+- **Rate limits (429/529)** - Parse `Retry-After`, `x-ratelimit-reset-*`, Anthropic epoch headers
+- **Gemini empty candidates** - Retry with prompt modification (append `.`, `?`, `!`)
+- **Server errors (5xx)** - Exponential backoff
+- **Context too long** - Could trigger compression, or fatal
+- **Auth errors (401/403)** - Fatal, no retry
+
+### Centralized error handling
+
+```rust
+pub struct ErrorContext<'a> {
+    pub event_tx: &'a mpsc::Sender<ResponseEvent>,
+    pub runtime: &'a AgentRuntime,
+    pub batch_id: Option<SnowflakePosition>,
+}
+
+pub async fn handle_processing_error(
+    ctx: &ErrorContext<'_>,
+    agent: &dyn Agent,
+    error: &ProcessingError,
+) -> LoopOutcome
+```
+
+`run_error_recovery` moves from `DatabaseAgent` impl to free function.
+
+### Force-execution helper
+
+```rust
+pub struct ConstraintViolation {
+    pub required_tools: Vec<String>,
+    pub violation_type: ConstraintType,
+}
+
+pub enum ConstraintType {
+    StartConstraint,
+    ExitRequirement,
+}
+
+pub async fn force_execute_required_tools(
+    ctx: &ProcessingContext<'_>,
+    state: &mut ProcessingState,
+    event_tx: &mpsc::Sender<ResponseEvent>,
+    violation: &ConstraintViolation,
+) -> Vec<ToolResponse>
+```
+
+### Main loop flow
+
+```rust
+pub async fn run_processing_loop(
+    ctx: ProcessingContext<'_>,
+    state: &mut ProcessingState,
+    event_tx: &mpsc::Sender<ResponseEvent>,
+    initial_message: Message,
+    heartbeat_sender: &HeartbeatSender,
+) -> Result<LoopOutcome, ProcessingError> {
+    // 1. Build initial request
+    let mut request = ctx.runtime.prepare_request(...).await?;
+
+    loop {
+        // 2. Call model with retry
+        let response = complete_with_retry(&ctx, &mut request, &config).await?;
+
+        // 3. Store response messages
+        store_response_messages(&ctx, state, &response).await?;
+
+        // 4. Process content blocks IN ORDER (inline tool execution)
+        let mut tool_responses = Vec::new();
+        let mut pending_action = ToolAction::Continue;
+
+        for item in iter_content_items(&response.content) {
+            match item {
+                ContentItem::Text(text) => emit_text_event(...),
+                ContentItem::Thinking(text) => emit_reasoning_event(...),
+                ContentItem::ToolUse { id, name, input } => {
+                    let outcome = execute_and_emit_tool(...).await?;
+                    tool_responses.push(outcome.response);
+
+                    if !matches!(outcome.action, ToolAction::Continue) {
+                        pending_action = outcome.action;
+                        break;  // Early exit
+                    }
+                }
+                ContentItem::Other => {}
+            }
+        }
+
+        // 5. Store tool responses
+        emit_and_store_tool_responses(...).await?;
+
+        // 6. Handle heartbeat exit
+        if let ToolAction::RequestHeartbeat { .. } = pending_action {
+            send_heartbeat(...)?;
+            return Ok(LoopOutcome::HeartbeatRequested { ... });
+        }
+
+        // 7. Check exit conditions and requirements
+        let should_exit = matches!(pending_action, ToolAction::ExitLoop)
+            || ctx.runtime.should_exit_loop(&state.process_state);
+        let needs_continuation = !tool_responses.is_empty();
+
+        if should_exit || !needs_continuation {
+            let pending = ctx.runtime.get_pending_exit_requirements(...);
+            if !pending.is_empty() {
+                // Retry logic for exit requirements
+            } else {
+                break;  // Clean exit
+            }
+        }
+
+        // 8. Prepare continuation
+        request = ctx.runtime.prepare_request(...).await?;
+    }
+
+    ctx.runtime.complete_batch(ctx.batch_id);
+    Ok(LoopOutcome::Completed { metadata })
+}
+```
+
+### Tool execution on runtime
+
+Move action determination into the runtime. The runtime understands tool rules and process state - it should determine what action to take.
+
+```rust
+// In pattern_core/src/runtime/mod.rs (or tool execution module)
+
+pub enum ToolAction {
+    Continue,
+    ExitLoop,
+    RequestHeartbeat { tool_name: String, call_id: String },
+}
+
+pub struct ToolExecutionOutcome {
+    pub response: ToolResponse,
+    pub action: ToolAction,
+}
+
+impl AgentRuntime {
+    /// Execute tool and determine resulting action based on rules and process state
+    pub async fn execute_tool_checked(
+        &self,
+        call: &ToolCall,
+        batch_id: SnowflakePosition,
+        process_state: &mut ProcessState,
+        meta: &ExecutionMeta,
+    ) -> Result<ToolExecutionOutcome, ToolExecutionError> {
+        let result = self.execute_tool(call, batch_id, process_state, meta).await?;
+
+        let action = if meta.request_heartbeat && !result.has_continue_rule {
+            ToolAction::RequestHeartbeat {
+                tool_name: call.fn_name.clone(),
+                call_id: call.call_id.clone(),
+            }
+        } else if self.should_exit_loop(process_state) {
+            ToolAction::ExitLoop
+        } else {
+            ToolAction::Continue
+        };
+
+        Ok(ToolExecutionOutcome {
+            response: result.response,
+            action,
+        })
+    }
+}
+```
+
+Processing loop just emits events and uses the action:
+
+```rust
+ContentItem::ToolUse { id, name, input } => {
+    emit_event(event_tx, ResponseEvent::ToolCallStarted { ... }).await;
+
+    let meta = build_execution_meta(id, input);
+    let call = build_tool_call(id, name, input);
+
+    match ctx.runtime.execute_tool_checked(&call, ctx.batch_id, &mut state.process_state, &meta).await {
+        Ok(outcome) => {
+            emit_event(event_tx, ResponseEvent::ToolCallCompleted {
+                call_id: id.to_string(),
+                result: Ok(outcome.response.content.clone()),
+            }).await;
+
+            tool_responses.push(outcome.response);
+
+            if !matches!(outcome.action, ToolAction::Continue) {
+                pending_action = outcome.action;
+                break;
+            }
+        }
+        Err(e) => { /* constraint violation handling */ }
+    }
+}
+```
+
+### Slimmed db_agent.rs
+
+```rust
+async fn process(
+    self: Arc<Self>,
+    message: Message,
+) -> Result<Box<dyn Stream<Item = ResponseEvent> + Send + Unpin>, CoreError> {
+    // Setup batch, state
+    self.set_state(AgentState::Processing { ... }).await?;
+
+    let (tx, rx) = mpsc::channel(100);
+
+    tokio::spawn(async move {
+        let ctx = ProcessingContext { ... };
+        let mut state = ProcessingState { ... };
+
+        let outcome = run_processing_loop(ctx, &mut state, &tx, message, &heartbeat).await;
+
+        // Emit Complete event
+        // Reset to Ready state
+    });
+
+    Ok(Box::new(ReceiverStream::new(rx)))
+}
+```
+
+~50 lines instead of ~800.
+
+## Implementation steps
+
+1. **Runtime changes** - Add `ToolAction`, `ToolExecutionOutcome`, `execute_tool_checked()` to `AgentRuntime`
+2. **Create module structure** - `agent/processing/` with `mod.rs`, `content.rs`, `errors.rs`, `retry.rs`, `loop_impl.rs`
+3. **Implement `content.rs`** - `ContentItem` enum and `iter_content_items()`
+4. **Implement `errors.rs`** - `ProcessingError`, `handle_processing_error()`, move `run_error_recovery()` from db_agent
+5. **Implement `retry.rs`** - `RetryConfig`, `complete_with_retry()`, error classification with rate limit parsing
+6. **Implement `loop_impl.rs`** - helper functions:
+   - `emit_event()`
+   - `store_response_messages()`
+   - `emit_and_store_tool_responses()`
+   - `handle_start_constraint_violation()`
+   - `force_execute_required_tools()`
+   - `add_exit_reminder()` / `add_start_reminder()`
+   - `send_heartbeat()`
+7. **Implement `run_processing_loop()`** - main orchestration function
+8. **Refactor `db_agent.rs`** - slim down to struct, builder, `Agent` trait impl calling `run_processing_loop()`
+9. **Remove dead code** - old loop logic, moved functions
+10. **Update tests** - ensure existing tests pass, add new unit tests
+
+## Testing
+
+- Existing tests should continue to pass (behaviour preserved)
+- Add unit tests for:
+  - `iter_content_items()` with both content formats
+  - `complete_with_retry()` with various error scenarios
+  - `force_execute_required_tools()`
+- Integration tests for inline execution ordering
+
+## Migration notes
+
+- No API changes to `Agent` trait
+- No changes to `ResponseEvent` variants
+- Internal refactor only - callers unaffected

+# Shell tool and ProcessSource design
+
+## Summary
+
+Add shell command execution capability to Pattern agents via two components:
+
+1. **ProcessSource** - `DataStream` impl managing process lifecycles, streaming output to blocks
+2. **Shell tool** - builtin tool exposing execute/spawn/kill/status operations
+
+Design priorities: safety first (permission tiers, path sandboxing), real shell behaviour (PTY session), swappable backends (local → container → remote).
+

+### Execution modes
+
+**One-shot (`execute`):**
+- Runs command in PTY session, waits for completion
+- Returns stdout/stderr/exit_code directly in ToolOutput
+- No block created, no notifications
+- Session state (cwd, env) persists across calls
+
+**Streaming (`spawn`):**
+- Starts long-running process
+- Output streams to pinned Loro block
+- Notifications emitted on output chunks and exit
+- Block auto-unpins after configurable interval post-exit
+
+## ProcessSource
+
+```rust
+pub struct ProcessSource {
+    source_id: String,
+    ctx: Arc<dyn ToolContext>,
+
+    // Execution backend (swappable)
+    backend: Arc<dyn ShellBackend>,
+
+    // Running processes: task_id → ProcessHandle
+    processes: DashMap<String, ProcessHandle>,
+
+    // Notification broadcast
+    tx: broadcast::Sender<Notification>,
+}
+
+struct ProcessHandle {
+    task_id: String,
+    block_label: String,           // "process:{task_id}"
+    started_at: SystemTime,
+    command: String,
+    unpin_after: Option<Duration>, // auto-unpin delay after exit
+}
+```
+
+### Shell backend trait
+
+```rust
+trait ShellBackend: Send + Sync {
+    fn execute(&self, command: &str, timeout: Duration) -> Result<ExecuteResult>;
+    fn spawn_streaming(&self, command: &str) -> Result<(TaskId, broadcast::Receiver<OutputChunk>)>;
+    fn kill(&self, task_id: &TaskId) -> Result<()>;
+}
+
+struct LocalPtyBackend { session: PtySession }
+struct DockerBackend { container_id: String, ... }      // future
+struct BubblewrapBackend { sandbox_config: ... }        // future
+```
+
+### PTY session management
+
+Use `pty` crate to maintain a real shell session:
+
+```rust
+struct PtySession {
+    pty: PtyMaster,
+    shell_pid: u32,
+}
+
+const PROMPT_MARKER: &str = "\x1b]pattern\x07"; // OSC escape sequence
+
+impl LocalPtyBackend {
+    fn init_session(&mut self) -> Result<()> {
+        // Set custom prompt for command completion detection
+        write!(self.session.pty, "PS1='{}'\n", PROMPT_MARKER)?;
+        Ok(())
+    }
+
+    fn execute(&self, command: &str, timeout: Duration) -> Result<ExecuteResult> {
+        // Write command to PTY
+        write!(self.session.pty, "{}\n", command)?;
+
+        // Read until prompt marker returns
+        let output = self.read_until_prompt(timeout)?;
+
+        Ok(output)
+    }
+}
+```
+
+Benefits of PTY approach:
+- `cd`, `export`, aliases just work naturally
+- Shell maintains its own state
+- Can swap backend without changing semantics
+
+## Shell tool
+
+### Input types
+
+```rust
+#[derive(Debug, Clone, Serialize, Deserialize, JsonSchema)]
+#[serde(rename_all = "snake_case")]
+pub enum ShellOp {
+    Execute,
+    Spawn,
+    Kill,
+    Status,
+}
+
+#[derive(Debug, Clone, Serialize, Deserialize, JsonSchema)]
+pub struct ShellInput {
+    pub op: ShellOp,
+
+    #[serde(default, skip_serializing_if = "Option::is_none")]
+    pub command: Option<String>,
+
+    #[serde(default, skip_serializing_if = "Option::is_none")]
+    pub timeout: Option<u64>,  // seconds, for execute
+
+    #[serde(default, skip_serializing_if = "Option::is_none")]
+    pub task_id: Option<String>,  // for kill
+}
+```
+
+### Operation behaviours
+
+| Op | Required params | Returns |
+|----|-----------------|---------|
+| `execute` | `command` | `ToolOutput` with stdout, stderr, exit_code in data |
+| `spawn` | `command` | `ToolOutput` with task_id, block_label |
+| `kill` | `task_id` | `ToolOutput` success/failure |
+| `status` | none | `ToolOutput` with list of running processes |
+
+### Execute response
+
+```json
+{
+  "stdout": "...",
+  "stderr": "...",
+  "exit_code": 0,
+  "duration_ms": 1234
+}
+```
+
+Non-zero exit codes are NOT errors - agent decides significance.
+
+## Permission model
+
+### Permission tiers
+
+```rust
+#[derive(Debug, Clone, Copy, PartialEq, Eq, PartialOrd, Ord)]
+pub enum ShellPermission {
+    ReadOnly,   // git status, ls, cat, etc.
+    ReadWrite,  // file modifications, git commit
+    Admin,      // unrestricted
+}
+
+pub struct ShellPermissionConfig {
+    pub default: ShellPermission,
+    pub rules: Vec<(GlobPattern, ShellPermission)>,
+    pub allowed_paths: Vec<PathBuf>,
+    pub strict_path_enforcement: bool,
+}
+```
+
+### Path sandboxing
+
+```rust
+fn validate_paths(&self, command: &str, session_cwd: &Path) -> Result<()> {
+    for path in extract_paths(command) {
+        let resolved = if path.is_absolute() {
+            path.canonicalize()?
+        } else {
+            session_cwd.join(path).canonicalize()?
+        };
+
+        if !self.is_within_allowed(&resolved) {
+            return Err(ShellError::PathOutsideSandbox(resolved));
+        }
+    }
+    Ok(())
+}
+```
+
+Enforcement layers:
+1. Session cwd clamping - `cd` outside allowed paths rejected
+2. Command path scanning - absolute paths outside bounds rejected
+3. Relative path resolution - `../../../etc/passwd` canonicalized and checked
+
+Not bulletproof (shell expansion, symlinks) - defense in depth. Container backend is the real sandbox.
+
+### Command classification
+
+Start simple: denylist of dangerous patterns (`rm -rf /`, `sudo`, `chmod`, `mkfs`). Everything else is `ReadWrite`. Iterate later.
+
+## Block structure
+
+For streaming processes, output goes to a Loro block:
+
+```rust
+// Block label: "process:{task_id}"
+// BlockSchema::Process
+
+struct ProcessBlock {
+    // Metadata (set at spawn)
+    command: String,
+    cwd: String,
+    started_at: i64,
+
+    // Streaming content
+    stdout: LoroText,
+    stderr: LoroText,
+
+    // Completion (set on exit)
+    exit_code: Option<i32>,
+    ended_at: Option<i64>,
+}
+```
+
+Separate stdout/stderr fields (not interleaved) - agent can focus on just errors if needed.
+
+### Block lifecycle
+
+- Created as **pinned** on `spawn`
+- On process exit, start auto-unpin timer (default: 5 min)
+- Agent can manually pin to keep, or unpin early
+- Block stays in store for history even when unpinned
+
+### Notifications
+
+```rust
+// On output chunk
+Notification {
+    message: "process abc123: 42 bytes stdout",
+    blocks: vec![block_ref],
+}
+
+// On exit
+Notification {
+    message: "process abc123 exited with code 0",
+    blocks: vec![block_ref],
+}
+```
+
+## Error handling
+
+```rust
+#[derive(Debug, Error)]
+pub enum ShellError {
+    #[error("permission denied: requires {required:?}, have {granted:?}")]
+    PermissionDenied { required: ShellPermission, granted: ShellPermission },
+
+    #[error("path outside sandbox: {0}")]
+    PathOutsideSandbox(PathBuf),
+
+    #[error("command denied by policy: {0}")]
+    CommandDenied(String),
+
+    #[error("command timed out after {0:?}")]
+    Timeout(Duration),
+
+    #[error("process spawn failed: {0}")]
+    SpawnFailed(#[source] std::io::Error),
+
+    #[error("pty error: {0}")]
+    PtyError(String),
+
+    #[error("unknown task: {0}")]
+    UnknownTask(String),
+
+    #[error("task already completed")]
+    TaskCompleted,
+}
+```
+
+### Error → ToolOutput mapping
+
+| Error | ToolOutput | Rationale |
+|-------|------------|-----------|
+| PermissionDenied | `error(msg)` | agent should know why |
+| PathOutsideSandbox | `error(msg)` | agent should adjust path |
+| Timeout | `success_with_data` with partial output | partial output useful |
+| SpawnFailed | `error(msg)` | nothing to show |
+| UnknownTask | `error(msg)` | stale task_id |
+
+## Future extensibility
+
+### Container backends (v2)
+
+- `DockerBackend` - spawn shell in container, mount allowed_paths
+- `BubblewrapBackend` - lightweight linux sandboxing
+- Backend selection via config
+
+### Capability-based permissions (v2)
+
+```rust
+struct Capabilities {
+    fs_read: bool,
+    fs_write: bool,
+    network: bool,
+    process_spawn: bool,
+}
+
+impl From<ShellPermission> for Capabilities { ... }
+```
+
+Simple tiers map to capability sets internally, exposed for advanced config later.
+
+### Output access op (v2)
+
+Add `output` operation to fetch current block content for running process without waiting for notification.
+
+### Remote connectors (future)
+
+- `LocalProcessSource` (this design)
+- `RemoteProcessSource` connects to user's machine via secure channel
+
+## Implementation steps
+
+1. Add `pty` dependency to pattern_core
+2. Create `ShellBackend` trait and `LocalPtyBackend`
+3. Create `ProcessSource` implementing `DataStream`
+4. Add `BlockSchema::Process` variant
+5. Create shell tool with execute/spawn/kill/status ops
+6. Implement permission checking and path sandboxing
+7. Wire up to tool registry
+8. Tests: unit tests for permissions/paths, integration tests for execution

+# Shell tool and ProcessSource implementation plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Add shell command execution capability to Pattern agents via ProcessSource (DataStream) and Shell tool (builtin).
+
+**Architecture:** PTY-based shell session (pty-process crate) wrapped in ShellBackend trait for future swappability. ProcessSource manages streaming processes with Loro blocks. Shell tool provides execute/spawn/kill/status operations.
+
+**Tech Stack:** pty-process (async), tokio broadcast channels, DashMap, Loro CRDT for block content.
+

+**Files:**
+- Create: `crates/pattern_core/src/data_source/process/mod.rs`
+- Modify: `crates/pattern_core/src/data_source/mod.rs`
+
+**Step 1: Create process module**
+
+```rust
+//! Process execution data source.
+//!
+//! Provides shell command execution capability through:
+//! - `ProcessSource`: DataStream impl managing process lifecycles
+//! - `ShellBackend`: Trait for swappable execution backends
+//! - `LocalPtyBackend`: PTY-based local execution
+
+mod backend;
+mod error;
+mod local_pty;
+
+pub use backend::{ExecuteResult, OutputChunk, ShellBackend, TaskId};
+pub use error::{ShellError, ShellPermission};
+pub use local_pty::LocalPtyBackend;
+```
+
+**Step 2: Add to data_source/mod.rs**
+
+Add after `mod file_source;`:
+
+```rust
+pub mod process;
+```
+
+And in the re-exports section, add:
+
+```rust
+pub use process::{
+    ExecuteResult, LocalPtyBackend, OutputChunk, ShellBackend, ShellError, ShellPermission, TaskId,
+};
+```
+
+**Step 3: Verify compilation**

+## Operations
+
+### execute
+Run a command and return its output.
+- command (required): The command to run
+- timeout (optional): Timeout in seconds (default: 60)
+
+Returns output (combined stdout/stderr), exit_code, and duration_ms.
+
+Example: {"op": "execute", "command": "git status"}
+
+### spawn
+Start a long-running command with streaming output to a block.
+- command (required): The command to run
+
+Returns task_id and block_label for the output block.
+
+Example: {"op": "spawn", "command": "cargo build --release"}
+
+### kill
+Terminate a running spawned process.
+- task_id (required): The task ID from spawn
+
+Example: {"op": "kill", "task_id": "abc12345"}
+
+### status
+List all running spawned processes.
+
+Example: {"op": "status"}
+
+## Notes
+
+- Session state (cwd, env vars) persists across execute calls
+- Use `cd` to change directories, `export` to set environment variables
+- Non-zero exit codes are reported in data, not as errors
+- spawn creates a pinned block that auto-unpins after process exit"#

+## Task 11: Register ShellTool in BuiltinTools
+
+**Files:**
+- Modify: `crates/pattern_core/src/tool/builtin/mod.rs`
+
+**Step 1: Update BuiltinTools struct**
+
+Find the `BuiltinTools` struct and add:
+
+```rust
+shell_tool: Option<Box<dyn DynamicTool>>,
+```
+
+**Step 2: Update constructor**
+
+In the `default_for_agent` or similar constructor, add after other tools:
+
+```rust
+// Shell tool is optional - requires ProcessSource to be configured
+shell_tool: None,
+```
+
+Add a new method to enable shell tool:
+
+```rust
+/// Enable shell tool with the given ProcessSource.
+pub fn with_shell_tool(mut self, source: Arc<ProcessSource>) -> Self {
+    self.shell_tool = Some(Box::new(DynamicToolAdapter::new(
+        ShellTool::new(Arc::clone(&self.ctx), source),
+    )));
+    self
+}
+```
+
+**Step 3: Update register_all**
+
+Add to `register_all`:
+
+```rust
+if let Some(ref tool) = self.shell_tool {
+    registry.register_dynamic(tool.clone_box());
+}
+```
+
+**Step 4: Update create_builtin_tool**
+
+Add to the match in `create_builtin_tool`:
+
+```rust
+// Note: Shell tool requires ProcessSource, can't be created standalone
+// "shell" => { ... }
+```
+
+**Step 5: Update BUILTIN_TOOL_NAMES**
+
+Add "shell" to the list.
+
+**Step 6: Verify compilation**
+
+Run: `cargo check -p pattern-core`
+Expected: SUCCESS
+
+**Step 7: Commit**
+
+```bash

+## Task 13: Add BlockSchema::Process variant (optional enhancement)
+
+**Files:**
+- Modify: `crates/pattern_core/src/memory/schema.rs`
+
+**Step 1: Consider if needed**
+
+The current implementation uses `BlockSchema::text()` for process output blocks. If you want structured process blocks with separate stdout/stderr fields, add a Process variant:
+
+```rust
+/// Process output with separate streams.
+Process {
+    /// Include stderr in the block.
+    include_stderr: bool,
+},
+```
+
+**Decision point:** This is optional. The text-based approach works fine for v1. Skip this task unless specifically requested.
+
+---
+
+## Task 14: Documentation and CLAUDE.md updates
+
+**Files:**
+- Modify: `crates/pattern_core/CLAUDE.md`
+
+**Step 1: Add shell tool documentation**
+
+Add a new section after the tool system documentation:
+
+```markdown
+## Shell Tool
+
+The shell tool provides command execution capability:
+
+### Operations
+- `execute`: One-shot command, returns combined output/exit_code
+- `spawn`: Long-running process with streaming output to block
+- `kill`: Terminate a spawned process
+- `status`: List running processes
+
+### Notes
+- PTY-based: stdout/stderr are interleaved (single `output` field)
+- Exit codes detected via nonce-based wrapper (prevents output injection)
+- Session death detected and auto-reinitialized
+
+### Security Model
+- Denied command patterns (rm -rf /, sudo, etc.)
+- Path sandboxing via `allowed_paths` config
+- Permission tiers: ReadOnly, ReadWrite, Admin
+
+### ProcessSource
+DataStream implementation managing shell processes:
+- Uses PTY for real shell session (cwd/env persist)
+- Swappable backend (LocalPtyBackend, future: Docker, Bubblewrap)
+- Streaming output to pinned Loro blocks
+- Auto-unpin after configurable delay post-exit
+```
+
+**Step 2: Commit**
+
+```bash
+git add crates/pattern_core/CLAUDE.md
+git commit -m "[pattern-core] document shell tool in CLAUDE.md"
+```
+
+---
+
+## Final verification
+
+After completing all tasks:
+
+**Step 1: Run full test suite**
+
+```bash
+cargo nextest run -p pattern-core
+```
+
+**Step 2: Run clippy**
+
+```bash
+cargo clippy -p pattern-core --all-features --all-targets
+```
+
+**Step 3: Format check**
+
+```bash
+cargo fmt --check
+```
+
+Expected: All pass with no warnings.

+# Config System Redesign Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Redesign the configuration system to establish clear TOML/DB ownership, remove vestigial user primitives, and support proper multi-agent config with merge semantics.
+
+**Architecture:** TOML defines agent structure and config metadata. DB owns content. Merge strategy by default with CLI override for primacy. `[[agents]]` replaces singular `[agent]`, `[user]` block removed, database path is directory not file.
+
+**Tech Stack:** Rust, TOML (serde), SQLx, pattern_core, pattern_cli, pattern_db
+
+**Reference:** Design doc at `docs/plans/2026-01-04-config-system-redesign.md`

+## Task 1: Add ConfigPriority enum and update DatabaseConfig
+
+**Files:**
+- Modify: `crates/pattern_core/src/config.rs`
+- Test: `crates/pattern_core/src/config.rs` (inline tests)
+
+**Step 1: Write failing tests for ConfigPriority and DatabaseConfig helpers**
+
+Add to `config.rs` in the test module:
+
+```rust
+#[test]
+fn test_database_config_directory_helpers() {
+    let temp_dir = tempfile::tempdir().unwrap();
+    let config = DatabaseConfig {
+        path: temp_dir.path().to_path_buf(),
+    };
+    assert_eq!(config.constellation_db(), temp_dir.path().join("constellation.db"));
+    assert_eq!(config.auth_db(), temp_dir.path().join("auth.db"));
+}
+
+#[test]
+fn test_config_priority_default() {
+    assert_eq!(ConfigPriority::default(), ConfigPriority::Merge);
+}
+```
+
+**Step 2: Run tests to verify they fail**
+
+Run: `cargo nextest run -p pattern-core test_database_config_directory_helpers test_config_priority_default`
+Expected: FAIL - methods/types don't exist
+
+**Step 3: Implement ConfigPriority and DatabaseConfig helpers**
+
+Add near top of `config.rs`:
+
+```rust
+/// Controls how TOML config and DB config are merged.
+#[derive(Debug, Clone, Copy, PartialEq, Eq, Default)]
+pub enum ConfigPriority {
+    /// DB values win for content, TOML wins for config metadata.
+    #[default]
+    Merge,
+    /// TOML overwrites everything except memory content.
+    TomlWins,
+    /// Ignore TOML entirely for existing agents.
+    DbWins,
+}
+```
+
+Update `DatabaseConfig` impl:
+
+```rust
+impl DatabaseConfig {
+    /// Path to the constellation database file.
+    pub fn constellation_db(&self) -> PathBuf {
+        self.path.join("constellation.db")
+    }
+
+    /// Path to the auth database file.
+    pub fn auth_db(&self) -> PathBuf {
+        self.path.join("auth.db")
+    }
+}
+```
+
+**Step 4: Run tests to verify they pass**
+
+Run: `cargo nextest run -p pattern-core test_database_config_directory_helpers test_config_priority_default`
+Expected: PASS
+
+**Step 5: Commit**

+- Modify: `crates/pattern_cli/src/main.rs` (if needed)
+
+**Step 1: Add ConfigPriority to CLI args**
+
+```rust
+#[derive(Clone, Copy, Debug, Default, clap::ValueEnum)]

+**Step 1: Add deprecation detection in config loading**
+
+```rust

+# Config system redesign
+
+## Overview
+
+Redesign the Pattern configuration system to establish clear ownership between TOML files and database, eliminate vestigial user primitives, and support proper multi-agent configuration.
+
+## Goals
+
+1. Agents consistently load whether from config or DB
+2. Config goes into database canonically per agent and groups
+3. Config overridable from TOML with explicit priority control
+4. Memory block content is DB-authoritative; config metadata is TOML-updatable
+
+## Changes
+
+### TOML structure
+
+Remove `[user]` block entirely. Change singular `[agent]` to plural `[[agents]]`. Database path specifies directory, not file.
+
+```toml
+[database]
+path = "~/.local/share/pattern"  # directory containing both DBs
+
+[model]
+provider = "anthropic"
+model = "claude-sonnet-4-20250514"
+temperature = 0.7
+
+[[agents]]
+name = "Pattern"
+system_prompt = "You are Pattern, an ADHD support agent..."
+# or: config_path = "agents/pattern.toml"  # load from external file
+
+[agents.model]
+provider = "gemini"
+model = "gemini-2.5-flash"
+
+[agents.memory.persona]
+content = "I am Pattern..."
+permission = "read_only"
+memory_type = "core"
+pinned = true
+
+[agents.memory.working_notes]
+permission = "read_write"
+memory_type = "working"
+
+[[agents]]
+name = "Archivist"
+
+[[groups]]
+name = "main"
+description = "Primary support constellation"
+pattern = { type = "round_robin" }
+
+[[groups.members]]
+name = "Pattern"
+
+[[groups.members]]
+name = "TempHelper"
+agent_config = { name = "TempHelper", system_prompt = "..." }
+
+[groups.shared_memory.context]
+permission = "read_write"
+memory_type = "working"
+```
+
+### Config resolution
+
+Resolution order: CLI flags -> TOML file -> Database -> Hardcoded defaults
+
+CLI flag `--config-priority` controls merge behavior:
+- `merge` (default): DB values win for content, TOML wins for config metadata
+- `toml`: TOML overwrites everything except memory content
+- `db`: Ignore TOML entirely for existing agents
+
+### Load behavior
+
+On `load_agent("Pattern")`:
+
+1. Check if agent exists in DB
+2. If exists AND TOML defines same agent name:
+   - Merge mode: DB content preserved, TOML config metadata applied
+   - TOML priority: TOML overwrites config, DB content preserved
+   - DB priority: Ignore TOML entirely
+3. If exists but no TOML definition: load from DB as-is
+4. If not in DB but TOML defines it: create in DB from TOML (seed)
+5. If neither: error
+
+### Memory block merge rules
+
+| Field | Source of truth | Merge behavior |
+|-------|-----------------|----------------|
+| `content` | DB | TOML only seeds new blocks |
+| `permission` | TOML | Updated on reload if specified |
+| `memory_type` | TOML | Updated on reload if specified |
+| `description` | TOML | Updated on reload if specified |
+| `pinned` | TOML | Updated on reload if specified |
+| `char_limit` | TOML | Updated on reload if specified |
+| `schema` | TOML | Updated on reload if specified |
+| `shared` | TOML | Updated on reload if specified |
+
+### Groups
+
+Group definitions from TOML always update DB. Member list from TOML replaces DB member list. Shared memory follows same rules as agent memory.
+
+Members can reference existing agents by name or define inline agent configs for group-specific agents.
+
+## Code changes
+
+### pattern_core/src/config.rs
+
+- Remove `UserConfig` struct
+- Remove `ensure_stable_user_id` function and related logic (~80 lines)
+- Rename `PatternConfig.agent` to `PatternConfig.agents: Vec<AgentConfigRef>`
+- Add `AgentConfigRef` enum for inline vs file reference:
+
+```rust
+#[derive(Debug, Clone, Serialize, Deserialize)]
+#[serde(untagged)]
+pub enum AgentConfigRef {
+    Inline(AgentConfig),
+    Path { config_path: PathBuf },
+}
+```
+- Change `DatabaseConfig.path` to directory, add helpers:
+
+```rust
+impl DatabaseConfig {
+    pub fn constellation_db(&self) -> PathBuf {
+        self.path.join("constellation.db")
+    }
+    pub fn auth_db(&self) -> PathBuf {
+        self.path.join("auth.db")
+    }
+}
+```
+
+- Add `ConfigPriority` enum:
+
+```rust
+pub enum ConfigPriority {
+    Merge,
+    TomlWins,
+    DbWins,
+}
+```
+
+- Expand `MemoryBlockConfig`:
+
+```rust
+pub struct MemoryBlockConfig {
+    // Content (TOML seeds, DB authoritative)
+    pub content: Option<String>,
+    pub content_path: Option<PathBuf>,
+
+    // Config (TOML can update on reload)
+    pub permission: MemoryPermission,
+    pub memory_type: MemoryType,
+    pub description: Option<String>,
+    pub pinned: Option<bool>,
+    pub char_limit: Option<usize>,
+    pub schema: Option<BlockSchema>,
+
+    // Sharing
+    pub id: Option<MemoryId>,
+    pub shared: bool,
+}
+```
+
+### pattern_core/src/runtime/context.rs
+
+- Update `resolve_config` to take `ConfigPriority` parameter
+- Add memory block config-vs-content merge logic
+- Update `create_agent` to handle "agent exists" case with merge
+
+### pattern_db/src/queries/memory.rs
+
+Add query for updating config without touching content:
+
+```rust
+pub async fn update_block_config(
+    pool: &SqlitePool,
+    block_id: i64,
+    permission: Option<MemoryPermission>,
+    block_type: Option<MemoryBlockType>,
+    description: Option<&str>,
+    pinned: Option<bool>,
+    char_limit: Option<usize>,
+) -> Result<()>
+```
+
+### pattern_cli/src/commands/
+
+- Add `--config-priority` flag to relevant commands
+- Update config loading to use new `agents` field
+- Remove any `user` references
+- Add `pattern config migrate` command
+
+## Testing
+
+Test module at `pattern_core/src/config/tests.rs`:

+```
+
+## Migration
+
+### Detection and errors
+
+```rust
+if parsed.get("agent").is_some() && parsed.get("agents").is_none() {
+    return Err(CoreError::ConfigurationError {
+        field: "agent".into(),
+        expected: "[[agents]] (plural)".into(),
+        cause: ConfigError::Deprecated(
+            "Singular [agent] is deprecated. Use [[agents]].\n\
+             Run: pattern config migrate"
+        ),
+    });
+}
+
+if parsed.get("user").is_some() {
+    tracing::warn!("[user] block is deprecated and ignored");
+}
+```
+
+### Migration command
+
+```bash
+pattern config migrate [--in-place] [path]
+```
+
+Transforms singular `[agent]` to `[[agents]]` and removes `[user]` block.
+
+### Timeline
+
+1. This release: Error on `[agent]`, warn on `[user]`, provide migration command
+2. No silent fallback - explicit errors preferred over magic

+# Delegation and orchestration system
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Enable agents to delegate work to other agents or spawn subagents, with streaming feedback and long-running orchestration.
+
+**Architecture:** Builds on existing coordination infrastructure. Adds delegation tracking, subagent lifecycle management with inherited memory access, goal-based orchestration, and internal triggers.
+
+**Tech Stack:** SQLite (pattern_db), existing agent/group infrastructure (pattern_core), streaming via existing event system.
+
+---
+
+## Summary
+
+Extend the agent coordination system to support:
+1. **Delegations** - Agent A requests work from Agent B (or spawns subagent), gets structured result
+2. **Subagents** - Ephemeral or persistent specialized agents with inherited read-only memory
+3. **Goals** - Long-running orchestration with hierarchical task breakdown
+4. **Internal triggers** - Recurring/event-driven agent-internal tasks
+
+All operations are intra-constellation (single database), but can cross group boundaries.
+
+## Problem
+
+Current coordination infrastructure supports:
+- `coordination_tasks` - Simple task assignment (no delegation tracking, no feedback)
+- `handoff_notes` - Informal notes (no structured results, no streaming)
+- Group patterns - Supervisor/RoundRobin/etc (message routing, not task delegation)
+
+Missing capabilities:
+- **Delegation with feedback** - Request work, get structured result back
+- **Subagent spawning** - Create specialized agent for specific work
+- **Inherited context** - Subagents shouldn't need explicit context packaging
+- **Progress streaming** - Real-time updates during long work
+- **Goal orchestration** - Break complex work into delegations over time
+- **Triggered tasks** - Agent-internal cron/event-driven work
+

+
+### Integration with existing coordination
+
+This system layers on top of existing coordination rather than replacing it:
+
+| Existing | New | Relationship |
+|----------|-----|--------------|
+| `coordination_tasks` | `delegations` | Tasks are simpler, delegations have full lifecycle |
+| `handoff_notes` | `delegation_updates` | Handoffs are informal, updates are structured |
+| `activity_events` | `delegation_updates` | Activity is audit log, updates are real-time |
+| Group patterns | Delegation to groups | Patterns route messages, delegations are task-oriented |
+
+The existing `coordination_tasks` can remain for simple "assign and track" use cases. Delegations are for richer agent-to-agent work with structured feedback.
+
+### Tools for agents
+
+Agents need tools to use this system. Following existing patterns (e.g. `block_edit`), use mode-based tools:
+
+```rust
+// Tool: delegation
+// Modes:
+//   - create: spawn delegation to agent/group/subagent
+//   - list: list delegations (filter by status, target, requester)
+//   - get: get delegation details + updates
+//   - update: report progress, partial results, blockers (for target agent)
+//   - cancel: cancel a pending/in-progress delegation (for requester)
+//   - complete: mark delegation complete with result (for target agent)
+
+// Tool: goal
+// Modes:
+//   - create: create new goal (optionally as subgoal)
+//   - list: list goals (filter by status, owner)
+//   - get: get goal details + child goals + delegations
+//   - update: update progress, add/remove blockers, set status
+//   - delete: remove goal (cascades to children)
+
+// Tool: trigger
+// Modes:
+//   - create: set up new trigger (cron/interval/event/condition)
+//   - list: list triggers (filter by enabled, owner)
+//   - get: get trigger details + fire history
+//   - update: modify trigger config
+//   - enable: enable trigger
+//   - disable: disable trigger
+//   - delete: remove trigger
+//   - fire: manually fire trigger (for testing)
+```
+
+---
+
+## Implementation steps
+
+### Phase 1: Database schema
+
+1. Add migration for new tables (`delegations`, `delegation_updates`, `subagents`, `agent_goals`, `internal_triggers`)
+2. Add indexes
+3. Run `sqlx prepare`
+
+### Phase 2: Core types (pattern_core)
+
+1. Create `coordination/delegation.rs` with delegation types
+2. Create `coordination/goals.rs` with goal types
+3. Create `coordination/triggers.rs` with trigger types
+4. Create `coordination/subagent.rs` with subagent types
+5. Update `coordination/mod.rs` to re-export
+
+### Phase 3: Database queries (pattern_db)
+
+1. Add `queries/delegation.rs` - CRUD for delegations and updates
+2. Add `queries/goals.rs` - CRUD for goals
+3. Add `queries/triggers.rs` - CRUD for triggers
+4. Extend `queries/agent.rs` - subagent-specific queries
+5. Run `sqlx prepare`
+
+### Phase 4: Subagent spawning
+
+1. Implement `spawn_subagent()` with memory inheritance
+2. Implement `cleanup_ephemeral_subagent()`
+3. Add tests for various inheritance modes
+
+### Phase 5: Delegation execution
+
+1. Implement `execute_delegation()` with streaming updates
+2. Implement `subscribe_delegation_updates()` for consumers
+3. Add delegation to group routing
+4. Add tests
+
+### Phase 6: Trigger execution
+
+1. Implement `check_triggers()` and `fire_trigger()`
+2. Implement `compute_next_fire()` with cron support (add `cron` crate)
+3. Add trigger checking to agent lifecycle (called periodically)
+4. Add tests
+
+### Phase 7: Agent tools
+
+1. Implement `delegation` tool with modes (create, list, get, update, cancel, complete)
+2. Implement `goal` tool with modes (create, list, get, update, delete)
+3. Implement `trigger` tool with modes (create, list, get, update, enable, disable, delete, fire)
+
+### Phase 8: Integration
+
+1. Wire trigger checking into agent runtime
+2. Add delegation status to agent context (so agents know about pending work)
+3. Update sleeptime pattern to use triggers
+
+---
+
+## Testing
+
+- Unit tests for each type's serialization
+- Unit tests for memory inheritance resolution
+- Integration tests for delegation execution flow
+- Integration tests for subagent spawn/cleanup
+- Integration tests for trigger firing
+- Property tests for cron next-fire computation
+
+## Design decisions
+
+1. **Delegation timeout** - Optional timeout field on delegations. On timeout: mark as failed, emit update, cleanup ephemeral subagent. Deadlines are soft hints, timeouts are hard limits.
+
+2. **Subagent resource limits** - Optional token budget and time limit fields on `SubagentConfig`. Enforced during execution. Ephemeral subagents especially benefit from limits.
+
+3. **Trigger backpressure** - Triggers cannot re-fire while a previous execution is still processing. Acts like a queued message. Add `in_flight` boolean to trigger state.
+
+4. **Cross-group visibility** - Within a constellation, all agents can see all delegations regardless of group membership. Groups are for coordination patterns, not access control.
+
+5. **Ephemeral memory transfer** - On ephemeral subagent cleanup, ownership of all subagent-created memory blocks transfers to the parent agent. Parent can consolidate/dedup later if desired. Archival entries transfer cleanly, working memory blocks may need agent attention.
+
+6. **Parent access to subagent memory** - Parent always has read-write access to any memory blocks created by their subagents (both ephemeral and persistent).
+
+---
+
+Plan complete and saved to `docs/plans/2026-01-04-delegation-orchestration-system.md`.
+
+**Two execution options:**
+
+1. **Subagent-Driven (this session)** - I dispatch fresh subagent per task, review between tasks, fast iteration
+
+2. **Parallel Session (separate)** - Open new session in worktree with executing-plans, batch execution with checkpoints
+
+Which approach? Or want to discuss the open questions / refine the design first?

+# Memory disk sync
+
+Sync memory block and archival entry contents to disk for auditability, version control, and debugging.
+
+## Goals
+
+- **Auditability**: Human-readable view of what's in agent memory
+- **Version control**: Files can be checked into git for history tracking
+- **Roundtrip**: Can import from disk to restore or debug memory state
+- **Compatibility**: Export format matches existing `MemoryBlockConfig` TOML structure
+
+## File format and structure
+
+### Directory layout
+
+```
+memory/
+└── {agent_name}/
+    ├── {label}.toml           # block metadata
+    ├── {label}.content.{ext}  # content file (md/json/jsonl)
+    └── archival/
+        └── {YYYY-MM}.md       # batched archival entries
+```
+
+### Block metadata (`.toml`)
+
+Matches existing `MemoryBlockConfig` format:
+
+```toml
+label = "persona"
+description = "Core identity and personality traits"
+memory_type = "core"
+permission = "read_write"
+pinned = true
+char_limit = 5000
+schema = "map"
+content_path = "persona.content.json"
+
+# Export-only fields (ignored on import)
+id = "block_abc123"
+agent_id = "aria"
+created_at = "2026-01-04T00:00:00Z"
+updated_at = "2026-01-04T12:00:00Z"
+```
+
+### Content file extensions by schema
+
+| Schema | Extension | Format |
+|--------|-----------|--------|
+| `text` | `.content.md` | Markdown |
+| `map` | `.content.json` | JSONC (comments allowed) |
+| `log` | `.content.jsonl` | JSON Lines (JSONC per line) |
+| `list` | `.content.json` | JSONC array |
+| `composite` | `.content.json` | JSONC with nested sections |
+
+### Archival entries
+
+Standalone markdown files batched by month. Entries separated by `---` with JSON metadata in code blocks:
+
+```markdown
+```json
+{"id": "entry_123", "created_at": "2026-01-03T10:00:00Z", "metadata": {"topic": "preferences"}}
+```
+
+User prefers morning check-ins. They find them helpful for setting daily priorities and are more receptive to suggestions early in the day.
+
+---
+
+```json
+{"id": "entry_124", "created_at": "2026-01-04T14:30:00Z", "metadata": {"topic": "patterns"}}
+```
+
+Deadline anxiety peaks 2 days before due date. This is when support should increase and task breakdown becomes more important.
+
+---
+```
+
+## Export (sync to disk)
+
+### CLI commands
+
+```bash
+# Export single agent
+pattern agent sync <name>
+pattern agent sync <name> --include-archival
+
+# Export all agents in group
+pattern group sync <name>
+pattern group sync <name> --include-archival
+
+# Common options
+--output-dir ./memory    # default: ./memory
+--dry-run                # show what would be written
+```
+
+### Export logic
+
+1. Load agent's memory blocks from DB
+2. For each block:
+   - Write `{label}.toml` with metadata
+   - Extract content from Loro doc according to schema
+   - Write `{label}.content.{ext}` in appropriate format
+3. If `--include-archival`:
+   - Query archival entries, group by month
+   - Write `archival/{YYYY-MM}.md` files
+
+### Runtime watch mode
+
+Watch mode is a runtime config option, not a CLI flag:
+
+```toml
+# In agent config or pattern config
+[memory_sync]
+enabled = true
+output_dir = "./memory"
+include_archival = false
+```
+
+When agent runs with sync enabled:
+- Initial full sync on startup
+- Memory operations (create, update, delete) trigger file writes/deletes
+- Archival entry creation appends to current month's file
+- Hooks into memory layer, not Loro specifically
+
+## Import (load from disk)
+
+Extends existing config import machinery.
+
+### CLI commands
+
+```bash
+# Import single block
+pattern agent config import <agent> --block ./memory/aria/persona.toml
+
+# Import all blocks from directory
+pattern agent config import <agent> --memory-dir ./memory/aria/
+
+# Import archival entries
+pattern agent config import <agent> --archival ./memory/aria/archival/2026-01.md
+```
+
+### Import behavior
+
+- Schema-aware content parsing (JSONC for maps/logs, markdown for text)
+- Uses existing `ConfigPriority` to handle conflicts:
+  - `Merge` (default): content from file, preserve existing CRDT history
+  - `TomlWins`: replace block entirely (fresh Loro doc)
+  - `DbWins`: skip import if block exists
+- For archival: parse `---`-separated entries, insert into DB
+- Regenerates `id`, `agent_id`, timestamps (label is the semantic key)
+
+### Schema-aware content loading
+
+Extend existing config loading to handle non-text blocks:
+
+```rust
+match (schema, content_path.extension()) {
+    (Text, "md") => doc.set_text(&content),
+
+    (Map, "json") => {
+        let map: Value = parse_jsonc(content);
+        for (key, value) in map.as_object() {
+            doc.set_field(key, value);
+        }
+    }
+
+    (Log, "jsonl") => {
+        for line in content.lines() {
+            let entry: LogEntry = parse_jsonc(line);
+            doc.append_log_entry(entry);
+        }
+    }
+
+    (List, "json") => {
+        let items: Vec<Value> = parse_jsonc(content);
+        doc.set_list(items);
+    }
+
+    (Composite, "json") => {
+        // Handle nested sections per schema definition
+    }
+}
+```
+
+JSONC parsing (JSON with comments) keeps files human-editable.
+
+## Implementation phases
+
+### Phase 1: Schema-aware import (prerequisite)
+
+Enables testability for everything else.
+
+- Extend `MemoryBlockConfig` loading to handle non-text schemas
+- Add JSONC parsing (strip `//` and `/* */` comments before serde)
+- Parse content files according to schema field
+- Apply to Loro doc correctly (set_text vs set_field vs append_log_entry)
+
+### Phase 2: Export (one-shot sync)
+
+- Add `pattern agent sync` command
+- Implement content extraction from Loro docs by schema type
+- Write `.toml` metadata + `.content.{ext}` files
+- Add `--include-archival` for archival entry export
+- Archival batched by month in markdown format
+
+### Phase 3: Import extensions
+
+- Add `--block`, `--memory-dir`, `--archival` flags to config import
+- Parse archival markdown format (JSON code blocks + content + `---` separators)
+- Handle `ConfigPriority` for conflict resolution
+
+### Phase 4: Runtime watch mode
+
+- Add `[memory_sync]` config section
+- Hook into memory layer for create/update/delete events
+- Initial sync on agent startup
+- File writes/deletes on memory operations

+# Bluesky Embed Handling Plan
+
+## Overview
+
+Enhance the Bluesky DataStream to properly handle post embeds (images, external links, quotes), display them in thread context, and support multi-modal messages for image content.
+
+## Current State
+
+The new BlueskyStream implementation using Jacquard does not handle embeds at all. The old implementation (`bluesky.rs.old`) had full embed support but used a custom `EmbedInfo` enum because atrium-api had different types and it stored its own `BlueskyPost` struct.
+
+### Old Implementation Text Formatting Style

+```
+
+### Old Image Collection
+- `collect_image_urls()` extracted URLs from embeds
+- `collect_all_image_urls()` gathered from entire thread
+- Selected last 4 images (prioritizing newer posts)
+- Appended as `[IMAGE: url]` markers at end of notification
+
+## Design Decision: No Custom Enum
+
+**We don't need a custom `EmbedInfo` enum.**
+
+Jacquard already provides `PostViewEmbed<'a>` with all variants:
+- `ImagesView(Box<images::View<'a>>)`
+- `VideoView(Box<video::View<'a>>)`
+- `ExternalView(Box<external::View<'a>>)`
+- `RecordView(Box<record::View<'a>>)`
+- `RecordWithMediaView(Box<record_with_media::View<'a>>)`
+
+We already store `PostView<'static>` from hydration, which contains `embed: Option<PostViewEmbed<'static>>` with all the data we need. Creating another enum would be redundant allocation and violates jacquard patterns.
+
+## Proposed Changes
+
+### Phase 1: EmbedDisplay Trait

+Create `crates/pattern_core/src/data_source/bluesky/embed.rs` with a trait mirroring `PostDisplay`:
+
+```rust
+use jacquard::api::app_bsky::feed::PostViewEmbed;
+use jacquard::api::app_bsky::embed::{images, external, record, record_with_media, video};
+
+/// Format embeds for display at various positions in the thread tree.
+/// Mirrors PostDisplay - different positions get different detail levels.
+pub trait EmbedDisplay {

+    fn format_for_main(&self, indent: &str) -> String;
+
+    /// Format for parent posts (condensed)
+    fn format_for_parent(&self, indent: &str) -> String;
+
+    /// Format for sibling/reply posts (condensed)
+    fn format_for_reply(&self, indent: &str) -> String;

+
+/// Max alt text length before truncation (chars)
+const ALT_TEXT_TRUNCATE: usize = 300;

+fn format_video(view: &video::View<'_>, buf: &mut String, indent: &str, compact: bool) {

+            format_video(view, buf, indent, compact);
+        }
+    }
+}
+```
+
+### Phase 2: Image Collection
+
+Add to `embed.rs`:
+
+```rust
+use jacquard::types::string::Uri;
+
+/// Collected image reference for multi-modal messages.
+/// Uses Uri<'static> to preserve jacquard types.
+pub struct CollectedImage {
+    pub thumb: Uri<'static>,
+    pub alt: String,  // Converted at collection time for simpler handling
+    pub position: usize,
+}
+
+/// Collect images from an embed.
+pub fn collect_images_from_embed(
+    embed: &PostViewEmbed<'_>,
+    position: usize,
+) -> Vec<CollectedImage> {
+    match embed {
+        PostViewEmbed::ImagesView(view) => {
+            view.images.iter().map(|img| CollectedImage {
+                thumb: img.thumb.clone().into_static(),
+                alt: img.alt.to_string(),  // Output boundary
+                position,
+            }).collect()
+        }
+        PostViewEmbed::RecordWithMediaView(view) => {
+            collect_images_from_media(&view.media, position)
+        }
+        PostViewEmbed::ExternalView(view) => {
+            // External link thumbnails can be included
+            view.external.thumb.as_ref().map(|t| vec![CollectedImage {
+                thumb: t.clone().into_static(),
+                alt: String::new(),
+                position,
+            }]).unwrap_or_default()
+        }
+        PostViewEmbed::VideoView(view) => {
+            // Video thumbnails
+            view.thumbnail.as_ref().map(|t| vec![CollectedImage {
+                thumb: t.clone().into_static(),
+                alt: view.alt.as_ref().map(|a| a.to_string()).unwrap_or_default(),
+                position,
+            }]).unwrap_or_default()
+        }
+        _ => Vec::new(),
+    }
+}
+```
+
+### Phase 3: Update PostDisplay Trait
+
+Modify `thread.rs` to use `EmbedDisplay` with matching position methods:
+
+```rust
+use super::embed::EmbedDisplay;
+
+impl PostDisplay for PostView<'_> {
+    fn format_as_root(&self, ctx: &ThreadContext<'_>) -> String {
+        // ... existing formatting ...
+        if let Some(embed) = &self.embed {
+            output.push_str(&embed.format_for_parent("   "));
+        }
+        // ...
+    }
+
+    fn format_as_parent(&self, ctx: &ThreadContext<'_>, indent: &str) -> String {
+        // ... existing formatting ...
+        if let Some(embed) = &self.embed {
+            output.push_str(&embed.format_for_parent(&format!("{}   ", indent)));
+        }
+        // ...
+    }
+
+    fn format_as_main(&self, ctx: &ThreadContext<'_>) -> String {
+        // ... existing formatting ...
+        // Main post gets full embed detail
+        if let Some(embed) = &self.embed {
+            output.push_str(&embed.format_for_main("│ "));
+        }
+        // ...
+    }
+
+    fn format_as_sibling(&self, ctx: &ThreadContext<'_>, indent: &str, is_last: bool) -> String {
+        // ... existing formatting ...
+        if let Some(embed) = &self.embed {
+            output.push_str(&embed.format_for_reply(&format!("{}   ", indent)));
+        }
+        // ...
+    }
+
+    fn format_as_reply(&self, ctx: &ThreadContext<'_>, indent: &str, depth: usize) -> String {
+        // ... existing formatting ...
+        if let Some(embed) = &self.embed {
+            output.push_str(&embed.format_for_reply(&format!("{}  ", indent)));
+        }
+        // ...
+    }
+}
+```
+
+**Position → EmbedDisplay method mapping:**
+| PostDisplay method | EmbedDisplay method | Detail level |
+|-------------------|---------------------|--------------|
+| `format_as_root` | `format_for_parent` | Condensed |
+| `format_as_parent` | `format_for_parent` | Condensed |
+| `format_as_main` | `format_for_main` | Full |
+| `format_as_sibling` | `format_for_reply` | Condensed |
+| `format_as_reply` | `format_for_reply` | Condensed |
+
+### Phase 4: Image Tracking
+
+Add to `BlueskyStreamInner`:
+
+```rust
+/// Images we've recently sent to the agent (keyed by thumb URL string)
+pub recently_shown_images: DashMap<String, Instant>,
+```
+
+Use `thumb.as_str()` for lookups (no allocation), only convert to owned String when inserting.
+
+### Phase 5: Multi-Modal Message Building
+
+Update `build_notification_with_thread` to collect images and build multi-modal:
+
+```rust
+// Collect images from thread, prioritizing newer posts
+let mut collected = Vec::new();
+// ... walk thread collecting images with position ...
+
+// Filter already-shown, sort by position desc, take MAX
+let selected: Vec<_> = collected
+    .into_iter()
+    .filter(|img| {
+        !self.recently_shown_images
+            .contains_key(img.thumb.as_str())
+    })
+    .sorted_by(|a, b| b.position.cmp(&a.position))
+    .take(MAX_IMAGES_PER_NOTIFICATION)
+    .collect();
+
+// Build message
+if selected.is_empty() {
+    Message::user(text)
+} else {
+    let mut parts = vec![ContentPart::Text(text)];
+    for img in selected {
+        // Mark as shown (allocation happens here at boundary)
+        self.recently_shown_images
+            .insert(img.thumb.to_string(), Instant::now());
+
+        parts.push(ContentPart::from_image_url("image/jpeg", img.thumb.as_str()));
+        if !img.alt.is_empty() {
+            parts.push(ContentPart::Text(format!("(Alt: {})", img.alt)));
+        }
+    }
+    Message::user_with_content(MessageContent::Parts(parts))
+}
+```
+
+## Jacquard Types Reference
+
+| Type | Key Fields |
+|------|------------|
+| `PostViewEmbed<'a>` | Enum: ImagesView, VideoView, ExternalView, RecordView, RecordWithMediaView |
+| `images::View<'a>` | `images: Vec<ViewImage<'a>>` |
+| `images::ViewImage<'a>` | `alt: CowStr`, `thumb: Uri`, `fullsize: Uri` |
+| `external::ViewExternal<'a>` | `uri: Uri`, `title: CowStr`, `description: CowStr`, `thumb: Option<Uri>` |
+| `record::ViewUnionRecord<'a>` | Enum: ViewRecord, ViewNotFound, ViewBlocked, ViewDetached, ... |
+| `record::ViewRecord<'a>` | `author: ProfileViewBasic`, `value: Data`, `uri: AtUri` |
+| `record_with_media::View<'a>` | `media: ViewMedia`, `record: record::View` |
+| `record_with_media::ViewMedia<'a>` | Enum: ImagesView, VideoView, ExternalView |
+| `video::View<'a>` | `alt: Option<CowStr>`, `thumbnail: Option<Uri>` |
+
+## Files to Modify
+
+| File | Changes |
+|------|---------|
+| `bluesky/embed.rs` | New - formatting functions, image collection |
+| `bluesky/mod.rs` | Add `mod embed;` |
+| `bluesky/thread.rs` | Call `format_embed()` in PostDisplay methods |
+| `bluesky/inner.rs` | Add `recently_shown_images`, update message building |
+
+## Implementation Order
+
+1. Create `embed.rs` with `format_embed()` and helper functions
+2. Add `collect_images_from_embed()`
+3. Update `thread.rs` PostDisplay to call formatting
+4. Add `recently_shown_images` to BlueskyStreamInner
+5. Update `build_notification_with_thread` for multi-modal messages
+6. Add cleanup for recently_shown_images cache
+
+## Multi-line Text Handling
+
+When post text or alt text spans multiple lines, we need to preserve indentation and box characters. Add a helper function:
+
+```rust
+/// Indent multi-line text, preserving box characters on continuation lines.
+///
+/// Example with indent="│ " and continuation="│ ":
+///   "line one\nline two\nline three"
+/// becomes:
+///   "│ line one\n│ line two\n│ line three"
+fn indent_multiline(text: &str, first_prefix: &str, continuation_prefix: &str) -> String {
+    let mut result = String::new();
+    for (i, line) in text.lines().enumerate() {
+        if i > 0 {
+            result.push('\n');
+            result.push_str(continuation_prefix);
+        } else {
+            result.push_str(first_prefix);
+        }
+        result.push_str(line);
+    }
+    // Handle trailing newline if original text had one
+    if text.ends_with('\n') {
+        result.push('\n');
+    }
+    result
+}
+```
+
+Usage in formatting functions:
+
+```rust
+// For quoted text in box style:
+let text = rec.value.get_at_path(".text").and_then(|v| v.as_str()).unwrap_or("");
+buf.push_str(&indent_multiline(text, &format!("{}│ {}: ", indent, author), &format!("{}│ ", indent)));
+
+// For alt text:
+let alt = truncate_alt(img.alt.as_str(), compact);
+buf.push_str(&indent_multiline(alt, &format!("{} alt: ", indent), &format!("{}      ", indent)));
+```
+
+This also applies to `thread.rs` PostDisplay - post text should be indented properly on continuation lines.
+
+## Key Jacquard Patterns Applied
+
+- **No custom enum**: Use `PostViewEmbed<'a>` directly
+- **Use `.as_str()` for display**: No allocation when formatting
+- **Use `.into_static()` only when storing**: CollectedImage.thumb
+- **Convert to String at output boundary**: When inserting to DashMap key, building ContentPart

+# Bluesky Thread Context Implementation Plan
+
+## Overview
+
+Port the thread context display from the old atrium-based implementation to jacquard, taking advantage of jacquard's cleaner types to significantly reduce boilerplate.
+
+## Key Insight: Jacquard Makes This Simpler
+
+The old implementation had extensive wrapper types (`BlueskyPost`, `EmbedInfo`, `HydrationState`) because atrium's types were awkward. Jacquard's types are designed to be used directly:
+
+| Old (atrium) | New (jacquard) |
+|--------------|----------------|
+| `BlueskyPost` wrapper | `PostView<'static>` directly |
+| `EmbedInfo` enum | `PostViewEmbed` union directly |
+| `HydrationState` tracking | Not needed - PostView comes hydrated |
+| Manual `from_post_view()` conversion | Just `.into_static()` when storing |
+| `ThreadContext.parent_chain: Vec<(BlueskyPost, Vec<BlueskyPost>)>` | Use `ThreadViewPost` tree directly |
+
+### ThreadViewPost Structure
+
+`GetPostThread` returns `ThreadViewPost` which already has the tree:
+
+```rust
+// app_bsky::feed::ThreadViewPost
+pub struct ThreadViewPost<'a> {
+    pub post: PostView<'a>,                                      // The post with author, embeds, counts
+    pub parent: Option<ThreadViewPostParent<'a>>,                // Parent chain (recursive)
+    pub replies: Option<Vec<ThreadViewPostRepliesItem<'a>>>,     // Reply tree (recursive)
+    pub thread_context: Option<ThreadContext<'a>>,               // Thread metadata
+}
+
+// Parent union - each parent can be a full post, not found, or blocked
+pub enum ThreadViewPostParent<'a> {
+    ThreadViewPost(Box<ThreadViewPost<'a>>),   // Recursive - has its own parent/replies
+    NotFoundPost(Box<NotFoundPost<'a>>),       // Post was deleted
+    BlockedPost(Box<BlockedPost<'a>>),         // Blocked by author or viewer
+}
+
+// Replies union - same variants as parent
+pub enum ThreadViewPostRepliesItem<'a> {
+    ThreadViewPost(Box<ThreadViewPost<'a>>),   // Each reply is a full thread node
+    NotFoundPost(Box<NotFoundPost<'a>>),
+    BlockedPost(Box<BlockedPost<'a>>),
+}
+```
+
+### GetPostThread Request/Response
+
+```rust
+// app_bsky::feed::get_post_thread::GetPostThread
+pub struct GetPostThread<'a> {
+    pub uri: AtUri<'a>,                    // Required - post URI to fetch thread for
+    pub depth: Option<i64>,                // Reply depth (default: 6, max: 1000)
+    pub parent_height: Option<i64>,        // Parent chain height (default: 80, max: 1000)
+}
+
+// Response output
+pub struct GetPostThreadOutput<'a> {
+    pub thread: GetPostThreadOutputThread<'a>,
+    pub threadgate: Option<ThreadgateView<'a>>,  // Reply restrictions if any
+}
+
+// Thread can also be not found or blocked at the root
+pub enum GetPostThreadOutputThread<'a> {
+    ThreadViewPost(Box<ThreadViewPost<'a>>),
+    NotFoundPost(Box<NotFoundPost<'a>>),
+    BlockedPost(Box<BlockedPost<'a>>),
+}
+```
+
+## What We Still Need
+
+### 1. ThreadContext (Simplified)
+
+```rust
+/// Thread context for display - wraps GetPostThread result with display helpers
+pub struct ThreadContext<'a> {
+    /// The thread tree from GetPostThread
+    pub thread: ThreadViewPost<'a>,
+
+    /// Posts in the current batch that should be highlighted
+    pub batch_uris: HashSet<AtUri<'a>>,
+
+    /// Agent's DID for [YOU] markers
+    pub agent_did: Option<Did<'a>>,
+
+    /// Whether this thread was recently shown (for abbreviated display)
+    pub recently_shown: bool,
+}
+```
+
+### 2. Display Formatting
+
+Methods on `ThreadContext` to format the tree:
+
+```rust
+impl ThreadContext<'_> {
+    /// Full thread tree display
+    pub fn format_full(&self) -> String { ... }
+
+    /// Abbreviated display (when recently shown)
+    pub fn format_abbreviated(&self) -> String { ... }
+
+    /// Format reply options for agent
+    pub fn format_reply_options(&self) -> String { ... }
+}
+```
+
+Display helpers that work directly on jacquard types:
+
+```rust
+/// Format a PostView for display at various positions in tree
+trait PostDisplay {
+    fn format_as_root(&self, agent_did: Option<&Did<'_>>) -> String;
+    fn format_as_parent(&self, agent_did: Option<&Did<'_>>, indent: &str) -> String;
+    fn format_as_main(&self, agent_did: Option<&Did<'_>>) -> String;
+    fn format_as_sibling(&self, agent_did: Option<&Did<'_>>, indent: &str, is_last: bool) -> String;
+    fn format_as_reply(&self, agent_did: Option<&Did<'_>>, indent: &str, depth: usize) -> String;
+}
+
+impl PostDisplay for PostView<'_> { ... }
+```
+
+### 3. Batching Logic
+
+Keep the existing batching by thread root, but enhance:
+
+```rust
+struct PendingBatch {
+    /// Posts grouped by thread root URI
+    posts_by_thread: DashMap<AtUri<'static>, Vec<FirehosePost>>,
+
+    /// Timer for each batch (when first post arrived)
+    batch_timers: DashMap<AtUri<'static>, Instant>,
+
+    /// Recently processed URIs (dedup)
+    processed_uris: DashMap<AtUri<'static>, Instant>,
+}
+```
+
+When flushing a batch:
+1. Collect all posts for that thread root
+2. Find the best "vantage point" (usually 1-2 parents above the most recent post)
+3. Call `GetPostThread` on that URI
+4. The batch posts should appear naturally in the tree (or be inserted if not)
+
+### 4. Thread Fetching
+
+```rust
+impl BlueskyStreamInner {
+    /// Fetch thread context for a post
+    async fn fetch_thread(
+        &self,
+        uri: AtUri<'_>,
+        depth: usize,
+        parent_height: usize,
+    ) -> Option<ThreadViewPost<'static>> {
+        let agent = self.authenticated_agent.as_ref()?;
+
+        let request = GetPostThread::new()
+            .uri(uri)
+            .depth(depth as i64)
+            .parent_height(parent_height as i64)
+            .build();
+
+        let response = match &**agent {
+            BlueskyAgent::OAuth(a) => a.send(request).await,
+            BlueskyAgent::Credential(a) => a.send(request).await,
+        };
+
+        match response {
+            Ok(resp) => {
+                let output = resp.into_output().ok()?;
+                match output.thread {
+                    GetPostThreadOutputThread::ThreadViewPost(tvp) => Some(tvp.into_static()),
+                    GetPostThreadOutputThread::BlockedPost(_) => None, // Can't see
+                    GetPostThreadOutputThread::NotFoundPost(_) => None,
+                    _ => None,
+                }
+            }
+            Err(e) => {
+                warn!("Failed to fetch thread: {}", e);
+                None
+            }
+        }
+    }
+}
+```
+
+### 5. User Blocks (Current Task)
+
+When we have a `PostView`, create/update user block from `post.author`:
+
+```rust
+async fn get_or_create_user_block(&self, author: &ProfileViewBasic<'_>) -> Option<BlockRef> {
+    let did = author.did.as_str();
+    let handle = author.handle.as_str();
+    let display_name = author.display_name.as_ref().map(|s| s.as_ref());
+    let avatar = author.avatar.as_ref().map(|s| s.as_ref());
+
+    // ... create/update block logic
+}
+```
+
+Note: `ProfileViewBasic` doesn't have `description`. For full profiles, we can call `GetProfiles` on unique DIDs from the thread.
+
+### 6. Constellation API (For Siblings)
+
+`GetPostThread` may not give us all siblings at each level. The constellation API at `https://constellation.microcosm.blue/links` can fill gaps:
+
+```rust
+/// Fetch posts that reply to the same parent (siblings)
+async fn fetch_siblings(&self, parent_uri: &str) -> Vec<AtUri> {
+    let url = format!(
+        "https://constellation.microcosm.blue/links?target={}&collection=app.bsky.feed.post&path=.reply.parent.uri",
+        urlencoding::encode(parent_uri)
+    );
+    // ... fetch and parse
+}
+```
+
+This is useful when the thread tree from GetPostThread is truncated.
+
+## Jacquard Patterns to Follow
+
+From the working-with-jacquard skill:
+
+1. **No `.to_string()` in loops** - use `.as_str()` or `.as_ref()`
+2. **`.into_static()` only when storing** - e.g., in DashMap or returning from function
+3. **Use `AtUri::new()` not `.parse()`** - zero-alloc for borrowed
+4. **Match on union variants** - always handle `Unknown` case
+5. **Borrow response, own when needed** - `.parse()` borrows, `.into_output()` owns
+
+## Files to Modify
+
+| File | Changes |
+|------|---------|
+| `data_source/bluesky.rs` | Add ThreadContext, display formatting, thread fetching |
+| `data_source/bluesky.rs` | Fix user block creation to use borrowed refs |
+| `data_source/bluesky.rs` | Update build_notification_hydrated to build thread context |
+
+## Implementation Order
+
+### Phase 1: Fix Current Code
+1. Fix string allocation antipatterns (`.to_string()` → `.as_str()`)
+2. Complete user block creation with proper borrowing
+
+### Phase 2: Thread Fetching
+3. Add `fetch_thread()` method using `GetPostThread`
+4. Handle blocked/not-found/gate cases
+
+### Phase 3: Thread Display
+5. Add `ThreadContext` struct (simplified)
+6. Implement `PostDisplay` trait for `PostView`
+7. Port display formatting from old impl (adapt for jacquard types)
+
+### Phase 4: Integration
+8. Update batch flush to fetch thread context
+9. Select best vantage point for batch
+10. Include batch posts in tree display
+11. Add thread caching and "recently shown" tracking
+
+### Phase 5: Constellation (if needed)
+12. Add sibling fetching via constellation API
+13. Merge siblings into thread tree
+
+## Display Format Examples
+
+### Full Thread Display

+
+## Handling Special Cases
+
+### Blocked Posts
+When `GetPostThread` returns `BlockedPost` in parent or replies:
+- Show placeholder: `[Blocked by author or viewer]`
+- Don't attempt to fetch or display content
+
+### Thread Gates
+When thread has reply restrictions:
+- Show warning: `⚠️ This thread has reply restrictions - you may not be able to reply`
+- Still show context for awareness
+
+### Not Found
+When post was deleted:
+- Show placeholder: `[Post not found - may have been deleted]`
+
+## Questions/Decisions
+
+1. **Constellation API necessity**: Does `GetPostThread` with reasonable depth/parent_height give us enough? Test first before adding constellation.
+
+2. **Profile descriptions**: Call `GetProfiles` for unique DIDs to get descriptions, or skip for now? (ProfileViewBasic lacks description)
+
+3. **Thread cache TTL**: Old impl used configurable TTL. Keep same pattern?

+```rust
+use pattern_core::memory::{MemoryCache, MemoryStore, BlockType};
 
-- Use `id.to_key()` for persistence (raw record key) and `RecordId::from(&id)` for query binds.
-- Use `id.to_string()` only for human-readable output (often includes a table prefix like `agent:` or `group:`).
-- Example: deriving a `MemoryId` or tracker key from a `GroupId` should use `group_id.to_key()`, not `group_id.to_string()`.
+// Create memory cache backed by pattern_db
+let memory = MemoryCache::new(dbs.clone());
 
-Caveat (rare acceptable `to_string()`): some IDs (e.g., `Did`, `MessageId`) display as their raw key without a table prefix. In those cases `to_string()` can be acceptable if you explicitly need the raw key string. Prefer `to_key()` when unsure.

 ### Memory Permissions and ACL
 
-- Levels: `read_only`, `partner`, `human`, `append`, `read_write` (default for new blocks), `admin`.
+- Levels: `read_only`, `partner`, `human`, `append`, `read_write` (default), `admin`.
 - ACL rules:
   - Read: allowed for all.
-  - Append: allowed for `append`/`read_write`/`admin`; `partner`/`human` require approval; `read_only` denied.
-  - Overwrite/Replace: allowed for `read_write`/`admin`; `partner`/`human` require approval; `append`/`read_only` denied.
-  - Delete: `admin` only (no consent path by default).
-- Tool behavior:
-  - `context.append`/`context.replace`: enforce ACL; auto-request approval (MemoryEdit { key }) when needed.
-  - `context.archive`: if target archival label already exists, enforce Overwrite ACL (approval if needed); deleting original context requires Admin.
-- `context.load`: 
-  - If `name` equals the archival label, flips the block to working in-memory (no deletion).
-  - Otherwise, creates a new working block under `name` and retains the archival source.
-  - Never deletes archival by default.
-  - `context.swap`: overwrite of destination context enforces ACL (approval if needed); deleting source archival requires Admin.
-  - `recall.append`: enforce ACL (approval if needed); `recall.delete`: Admin only.
-  - Consent prompts route to the originating channel (Discord) when available.

 ## Agent Naming, Roles, and Defaults
 
-- Agent names are arbitrary: features no longer depend on specific names like "Pattern", "Anchor", or "Archive".
+- Agent names are arbitrary: features no longer depend on specific names.
 - Group roles drive behavior:
-  - Supervisor: acts as orchestrator; data sources (e.g., Bluesky/Jetstream) route through the Supervisor by default.
-  - Specialist with domain "system_integrity": gets the SystemIntegrityTool.
-  - Specialist with domain "memory_management": gets the ConstellationSearchTool.
-- Sleeptime prompts are role/domain-based:

-# Partner Pre-Initialization Implementation Summary
-
-## Completed Work (2025-07-05)
-
-### 1. Configuration Updates ✅
-- Added `PartnersConfig` and `PartnerUser` structs to `src/config.rs`
-- Added `partners` field to main `Config` struct
-- Updated `pattern.toml` with partner configuration:
-  ```toml
-  [partners]
-  [[partners.users]]
-  discord_id = "549170854458687509"
-  name = "orual"
-  auto_initialize = true
-  ```
-
-### 2. Service-Level Initialization ✅
-- Added `initialize_partners()` method to `PatternService`
-- Partners are initialized after multi-agent system creation
-- Only partners with `auto_initialize = true` are pre-initialized at boot
-- Errors during partner initialization don't crash the service
-
-### 3. MultiAgentSystem Updates ✅
-- Added `initialize_partner()` method that:
-  - Parses Discord ID from string to u64
-  - Gets or creates database user by Discord ID
-  - Checks if already initialized (fast path)
-  - Initializes constellation if needed
-- Added `is_user_initialized()` method to check agent existence
-- Updated `build_system_prompt()` to accept partner_name and discord_id
-
-### 4. Discord Bot Fast Path ✅
-- Updated `process_message()` to use fast path checking
-- Only initializes constellation on first interaction
-- Subsequent messages skip initialization for 20-30s speedup
-
-### 5. System Prompt Updates ✅
-- Modified `build_system_prompt()` to handle partner placeholders
-- Replaces `{partner_name}` and `{discord_id}` in prompts
-- Falls back to "Unknown" when partner info not available
-
-## What Works Now
-
-1. **Boot-time Initialization**: Partners listed in `pattern.toml` with `auto_initialize = true` get their constellations created at startup
-2. **Fast Discord Responses**: Pre-initialized partners get instant responses instead of 20-30s delays
-3. **Flexible Configuration**: Easy to add/remove partners via config file
-4. **Error Resilience**: Failed partner init doesn't crash the service
-
-## Known Limitations
-
-1. **Partner Info in Prompts**: Currently passes `None` for partner info in most contexts
-   - Only the boot-time initialization has access to partner details
-   - Regular user initialization doesn't have partner name/discord_id
-   - Would need to store partner info in database to fully implement
-
-2. **No /partner Commands**: Slash commands for dynamic partner management not yet implemented
-
-3. **No Hot Reload**: Adding partners requires service restart
-
-## Next Steps
-
-To fully complete the partner system:
-
-1. **Store Partner Info in Database**:
-   - Add `is_partner` and `partner_name` fields to users table
-   - Update `initialize_partner()` to mark users as partners
-   - Retrieve partner info when building prompts
-
-2. **Implement /partner Slash Commands**:
-   - `/partner add @user` - Add a new partner
-   - `/partner list` - Show all partners
-   - `/partner remove @user` - Remove a partner
-
-3. **Thread Partner Info Through Agent Creation**:
-   - Pass user info through `create_agent()` flow
-   - Retrieve partner details from database
-   - Include in system prompt generation
-
-4. **Add Partner Status to Groups**:
-   - Groups could have different behavior for partners vs conversants
-   - Partner-specific memory blocks or tools

-# Partner Constellation Pre-Initialization Plan
-
-## Problem Statement
-Currently, agent constellations are created on first Discord message, causing significant delays:
-- Agent creation (6 agents × ~1-2s each)
-- Memory block creation (3 blocks × ~0.5s each)
-- Group creation (4 groups × ~2-3s each)
-- Total initialization time: 20-30 seconds
-
-## Proposed Solution
-Pre-create partner constellations at boot time for designated partners.
-
-## Implementation Plan
-
-### Phase 1: Configuration Changes
-
-1. **Update pattern.toml structure**:
-```toml
-[discord]
-token = "..."
-application_id = ...
-
-[partners]
-# Define partners who get pre-initialized constellations
-[[partners.users]]
-discord_id = "549170854458687509"
-name = "primary_partner"
-auto_initialize = true
-
-[[partners.users]]
-discord_id = "123456789012345678" 
-name = "secondary_partner"
-auto_initialize = false  # Can be initialized via slash command
-```
-
-2. **Add to Config struct**:
-```rust
-#[derive(Debug, Clone, Deserialize)]
-pub struct PartnersConfig {
-    pub users: Vec<PartnerUser>,
-}
-
-#[derive(Debug, Clone, Deserialize)]
-pub struct PartnerUser {
-    pub discord_id: String,
-    pub name: String,
-    pub auto_initialize: bool,
-}
-```
-
-### Phase 2: Boot-Time Initialization
-
-1. **Modify PatternService::start()**:
-   - After multi-agent system init, check for partners config
-   - For each partner with `auto_initialize = true`:
-     - Create database user if not exists
-     - Initialize full constellation (agents, memory, groups)
-   - Log initialization progress
-
-2. **Add method to MultiAgentSystem**:
-```rust
-pub async fn initialize_partner(&self, discord_id: &str, name: &str) -> Result<UserId> {
-    // Get or create database user
-    let user = self.db.get_or_create_user_by_discord_id(
-        discord_id.parse()?, 
-        name
-    ).await?;
-    
-    let user_id = UserId(user.id);
-    
-    // Initialize constellation
-    self.initialize_user(user_id).await?;
-    
-    info!("Partner {} initialized with user_id {}", name, user_id.0);
-    Ok(user_id)
-}
-```
-
-### Phase 3: Slash Command for Partner Management
-
-1. **Add new slash commands**:
-   - `/partner add @user` - Add someone as a partner and initialize their constellation
-   - `/partner remove @user` - Remove partner status (keeps agents)
-   - `/partner list` - Show all configured partners and their status
-
-2. **Implement partner management**:
-```rust
-async fn handle_partner_command(&self, ctx: &Context, command: &CommandInteraction) {
-    let subcommand = // parse subcommand
-    
-    match subcommand {
-        "add" => {
-            let mentioned_user = // get mentioned user
-            let discord_id = mentioned_user.id.to_string();
-            
-            // Add to database
-            self.db.add_partner(&discord_id, &mentioned_user.name).await?;
-            
-            // Initialize constellation
-            self.multi_agent_system.initialize_partner(&discord_id, &mentioned_user.name).await?;
-            
-            // Update config file (optional - for persistence across restarts)
-        }
-        // ... other subcommands
-    }
-}
-```
-
-### Phase 4: Optimize Discord Message Handling
-
-1. **Fast path for initialized partners**:
-```rust
-async fn process_message(&self, ctx: &Context, msg: &Message) -> Result<String> {
-    let state = self.state.read().await;
-    
-    // Get database user
-    let db_user = state.db
-        .get_or_create_user_by_discord_id(msg.author.id.get(), &msg.author.name)
-        .await?;
-    
-    let user_id = UserId(db_user.id);
-    
-    // Check if already initialized (fast path)
-    if state.multi_agent_system.is_user_initialized(user_id).await {
-        // Skip initialization, go straight to message processing
-        return state.multi_agent_system.send_message_to_agent(...).await;
-    }
-    
-    // Slow path: initialize on demand for non-partners
-    state.multi_agent_system.initialize_user(user_id).await?;
-    // ... continue as before
-}
-```
-
-2. **Add initialization check method**:
-```rust
-impl MultiAgentSystem {
-    pub async fn is_user_initialized(&self, user_id: UserId) -> bool {
-        // Check if user has agents in cache
-        self.user_agents.read().await.contains_key(&user_id)
-    }
-}
-```
-
-### Phase 5: Database Schema Updates
-
-1. **Add partners table** (optional - for persistence):
-```sql
-CREATE TABLE partners (
-    id INTEGER PRIMARY KEY AUTOINCREMENT,
-    user_id INTEGER NOT NULL,
-    added_by INTEGER,
-    added_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
-    FOREIGN KEY (user_id) REFERENCES users(id),
-    FOREIGN KEY (added_by) REFERENCES users(id),
-    UNIQUE(user_id)
-);
-```
-
-### Phase 6: Performance Monitoring
-
-1. **Add timing logs**:
-   - Boot-time initialization duration
-   - Per-message processing time
-   - Cache hit/miss rates
-
-2. **Metrics to track**:
-   - Time from Discord message to agent response
-   - Number of pre-initialized vs on-demand initializations
-   - Memory usage with pre-initialized constellations
-
-## Benefits
-
-1. **Immediate Response**: Partners get instant responses without initialization delay
-2. **Predictable Load**: Heavy initialization happens at boot, not during user interaction
-3. **Better UX**: No more "initializing..." messages for partners
-4. **Scalability**: Can control which users get pre-initialized constellations
-
-## Migration Path
-
-1. Deploy with auto_initialize = false for all partners
-2. Test with single partner via slash command
-3. Enable auto_initialize for primary partners
-4. Monitor performance and adjust
-
-## Future Enhancements
-
-1. **Lazy agent loading**: Initialize core agents first, specialists on demand
-2. **Agent hibernation**: Unload inactive agents after timeout
-3. **Warm standby pool**: Pre-create generic agents that can be assigned to users
-4. **Constellation templates**: Different agent sets for different partner types

+
+---
+
+## ACP Integration
+
+The Agent Client Protocol enables Pattern to work with any ACP-compatible editor (Zed, JetBrains, Neovim, etc.).
+
+### What is ACP?
+
+ACP is an open standard (from Zed) that decouples agents from editors:
+- **Agents** implement the `Agent` trait and run as subprocesses
+- **Clients** (editors) spawn agents and communicate via JSON-RPC over stdio
+- Agents can request file access, terminal execution, permissions from the client
+
+### Pattern as an ACP Agent
+
+Pattern would implement the `agent-client-protocol` crate's `Agent` trait:
+
+```rust
+use agent_client_protocol::{
+    Agent, AgentSideConnection,
+    InitializeRequest, InitializeResponse,
+    NewSessionRequest, NewSessionResponse,
+    PromptRequest, PromptResponse,
+    // ...
+};
+
+pub struct PatternAcpAgent {
+    /// The Pattern constellation/agent this wraps
+    db: Arc<ConstellationDb>,
+    agent_id: AgentId,
+    
+    /// Active sessions
+    sessions: DashMap<SessionId, PatternSession>,
+}
+

+        })
+    }
+    
+    async fn cancel(&self, req: CancelNotification) -> Result<()> {
+        if let Some(session) = self.sessions.get(&req.session_id) {
+            session.cancel().await;
+        }
+        Ok(())
+    }
+    
+    async fn load_session(&self, req: LoadSessionRequest) -> Result<LoadSessionResponse> {
+        // Pattern has full session persistence - can restore from DB
+        let session = PatternSession::load(&self.db, &req.session_id).await?;
+        
+        // Stream history back to client via notifications
+        for message in session.history().await? {
+            // Send as ContentChunk notifications
+        }
+        
+        self.sessions.insert(req.session_id.clone(), session);
+        Ok(LoadSessionResponse { /* ... */ })
+    }
+}
+```
+
+### Running as ACP Agent
+
+Pattern would provide a binary that speaks ACP over stdio:
+
+```bash
+# Invoked by editor (Zed, etc.)
+pattern-acp --constellation my-constellation --agent my-agent
+```
+
+The binary:
+1. Reads JSON-RPC from stdin
+2. Dispatches to `PatternAcpAgent` implementation
+3. Writes responses/notifications to stdout
+
+### ACP Client Capabilities Pattern Can Use
+
+When the client (editor) supports these, Pattern can:
+
+```rust
+// Read files from user's workspace
+let content = conn.request(ReadTextFileRequest {
+    path: "/path/to/file.rs".into(),
+}).await?;
+
+// Write files (with permission)
+conn.request(WriteTextFileRequest {
+    path: "/path/to/file.rs".into(),
+    content: new_content,
+}).await?;
+
+// Execute terminal commands
+let terminal = conn.request(CreateTerminalRequest {
+    command: "cargo".into(),
+    args: vec!["test".into()],
+    cwd: Some("/project".into()),
+    env: vec![],
+}).await?;
+
+// Wait for command and get output
+let result = conn.request(WaitForTerminalExitRequest {
+    terminal_id: terminal.id,
+}).await?;
+
+// Request permission for dangerous operations
+let permission = conn.request(RequestPermissionRequest {
+    tool_call_id: call_id,
+    tool_name: "shell_execute".into(),
+    description: "Run rm -rf on /tmp/build".into(),
+    options: vec![
+        PermissionOption { id: "allow".into(), label: "Allow".into(), kind: PermissionOptionKind::Allow },
+        PermissionOption { id: "deny".into(), label: "Deny".into(), kind: PermissionOptionKind::Deny },
+    ],
+}).await?;
+```
+
+### ACP vs Remote Presence Connector
+
+These solve different problems:
+
+| Aspect | ACP | Remote Presence Connector |
+|--------|-----|---------------------------|
+| Direction | Editor → Agent | Agent (on server) → User's machine |
+| Transport | stdio (local subprocess) | WebSocket (network) |
+| Use case | Editor integration | Server-hosted agent accessing local files |
+| Trust | Agent trusted by editor | Connector authenticated as partner |
+
+They can coexist:
+- Local Pattern: Runs as ACP agent, accessed by editor directly
+- Remote Pattern: Runs on server, uses connector for file access, could still speak ACP to local editor via tunnel
+
+---
+
+## WebSocket API
+
+For real-time bidirectional communication (Discord bot, live updates):
+
+```
+WS /api/v1/constellations/:cid/ws
+
+# Client → Server messages
+{ "type": "subscribe", "agent_id": "..." }
+{ "type": "message", "agent_id": "...", "content": "...", "source": "discord" }
+{ "type": "unsubscribe", "agent_id": "..." }
+
+# Server → Client messages
+{ "type": "response_event", "agent_id": "...", "event": { ... } }
+{ "type": "memory_update", "agent_id": "...", "block": "...", "content": "..." }
+{ "type": "error", "message": "..." }
+```
+
+---
+
+## CLI Commands (Preserved/Enhanced)
+
+The CLI remains the trusted local interface:
+
+```bash
+# Agent operations
+pattern agent list
+pattern agent create --name "MyAgent" --model anthropic/claude-3-5-sonnet
+pattern agent status MyAgent
+pattern agent export MyAgent -o agent.car
+
+# Interactive chat
+pattern chat --agent MyAgent
+pattern chat --group MyGroup
+
+# Memory inspection
+pattern debug list-core --agent MyAgent
+pattern debug search-archival --agent MyAgent --query "important"
+pattern debug show-context --agent MyAgent
+
+# Memory history (new in v2)
+pattern memory history --agent MyAgent --block persona
+pattern memory rollback --agent MyAgent --block persona --version <frontiers>
+
+# Export/Import
+pattern export constellation MyConstellation -o constellation.car
+pattern import --from constellation.car
+
+# ACP mode (new in v2)
+pattern acp --agent MyAgent  # Run as ACP agent for editor integration
+```
+
+---
+
+## Trust Levels and Tool Access
+
+Different API surfaces have different trust levels:
+
+| Interface | Trust Level | Default Tool Access |
+|-----------|-------------|---------------------|
+| CLI | Partner | All tools |
+| ACP (local editor) | Partner | All tools (editor controls permissions) |
+| HTTP API (authenticated) | Partner | All tools |
+| Remote Connector | Partner | All tools (connector authenticated) |
+| Discord | Conversant | Safe tools only |
+| Bluesky | Conversant | Safe tools only |
+| Unauthenticated | Untrusted | Read-only |
+
+Tool access can be further restricted per-agent via config.
+
+---
+
+## MCP Integration
+
+Pattern already has MCP client support. With ACP integration:
+
+1. **Editor provides MCP servers** - Via `NewSessionRequest.mcp_servers`
+2. **Pattern connects to them** - Uses existing `pattern_mcp` client
+3. **Tools from MCP servers** - Registered in Pattern's tool registry
+4. **Pattern can also expose MCP** - For other tools to call Pattern
+
+```
+┌─────────────┐     ACP      ┌─────────────┐     MCP     ┌─────────────┐
+│    Zed      │◄────────────►│   Pattern   │◄───────────►│  MCP Server │
+│   (Client)  │   stdio      │   (Agent)   │             │ (e.g. gh)   │
+└─────────────┘              └─────────────┘             └─────────────┘
+```
+
+---
+
+## ACP Connection Model
+
+One ACP connection = one Pattern entity:
+
+```bash
+# Connect to a single agent
+pattern acp --agent MyAgent
+
+# Connect to a group (coordination pattern routes internally)
+pattern acp --group MyGroup
+```
+
+When connecting to a **group**, the ACP session maps to the group's coordination pattern:
+- Messages route through the pattern manager (round-robin, dynamic, supervisor, etc.)
+- `session/update` notifications include which agent is responding
+- The group appears as a single "agent" to the editor
+
+This keeps the ACP interface simple while allowing Pattern's multi-agent coordination to work underneath.
+
+### Pattern vs Typical ACP Session Semantics
+
+**Important distinction:** Pattern's model differs from typical ACP agents.
+
+| Aspect | Typical ACP Agent | Pattern |
+|--------|-------------------|---------|
+| Session | Ephemeral conversation | Connection to persistent constellation |
+| History | Per-session, loaded on `session/load` | Always persistent in constellation DB |
+| `session/new` | Creates fresh context | Connects to existing agent, maybe specifies memory blocks to surface |
+| `session/load` | Restores saved conversation | Mostly no-op - constellation is always "loaded" |
+| Identity | Session-scoped | Long-term relationship with partner |
+
+Pattern would implement ACP sessions as "connection handles" rather than "conversation containers":
+
+```rust
+async fn new_session(&self, req: NewSessionRequest) -> Result<NewSessionResponse> {
+    // "Session" is just a connection to the persistent constellation
+    // No new conversation context created - agent already has full history
+    
+    let session = AcpSessionHandle {
+        constellation_id: self.constellation_id.clone(),
+        agent_id: self.agent_id.clone(),
+        // Optional: which memory blocks to emphasize in this connection
+        active_blocks: req.config.get("active_blocks").cloned(),
+        // MCP servers from editor
+        mcp_servers: req.mcp_servers,
+    };
+    
+    // Don't replay history - it's already in the agent's context
+    // Editor can request specific history via extension methods if needed
+    
+    Ok(NewSessionResponse {
+        session_id: SessionId::generate(),
+        // ...
+    })
+}
+
+async fn load_session(&self, req: LoadSessionRequest) -> Result<LoadSessionResponse> {
+    // Pattern doesn't really "load" sessions - constellation is persistent
+    // This could be used to switch which agent/group we're connected to
+    // or to specify a different memory configuration
+    
+    Ok(LoadSessionResponse { /* ... */ })
+}
+```
+
+This means Pattern agents maintain continuity across ACP connections - reconnecting picks up where you left off, because the agent never "forgot" anything.
+
+---
+
+---
+
+## Deployment Model
+
+### Single Canonical Server
+
+Pattern runs on a **single server** - this could be:
+- A home server (low latency, always-on, your hardware)
+- A cloud VPS (accessible from anywhere)
+- Your local machine (simplest, but not always-on)
+
+The key insight: **LLM API response latency dominates everything**. Network latency for file operations over iroh is negligible by comparison. So "local vs remote" for the server matters less than you'd think.
+
+### Multiple Entry Points, One Truth
+
+The server handles multiple concurrent connections:
+
+```
+┌─────────────────────────────────────────────────────────────────┐
+│                    Pattern Server (e.g., home server)           │
+│                                                                 │
+│  ┌────────────────────────────────────────────────────────┐    │
+│  │  Constellation                                          │    │
+│  │  └── Agents (Pattern, Flux, Entropy, Anchor, Archive)   │    │
+│  │  └── constellation.db (single source of truth)          │    │
+│  │  └── Shared context, coordination state                 │    │
+│  └────────────────────────────────────────────────────────┘    │
+│         ▲            ▲            ▲            ▲                │
+│         │            │            │            │                │
+│    Connector    Connector     Discord      Bluesky              │
+│    (laptop)    (desktop)       Bot        Firehose              │
+│         │            │            │            │                │
+└─────────┼────────────┼────────────┼────────────┼────────────────┘
+          │            │            │            │
+     ┌────▼────┐  ┌────▼────┐      │            │
+     │ Laptop  │  │ Desktop │   Discord     Bluesky
+     │  Zed    │  │  Zed    │   servers     servers
+     └─────────┘  └─────────┘
+```
+
+All entry points hit the same server, same constellation, same agents. No sync problem because there's one database.
+
+### Concurrent Message Handling
+
+When messages arrive simultaneously from different sources, Pattern handles them with **batch isolation**:
+
+```
+Timeline (actual processing):
+  t=0: Discord msg arrives, batch A starts
+  t=1: Bluesky mention arrives, batch B starts  
+  t=3: Connector request arrives, batch C starts
+  t=5: batch B completes (Bluesky was a quick reply)
+  t=8: batch C completes
+  t=12: batch A completes (Discord needed more thought)
+
+Agent's view during batch A:
+  [history up to t=0]
+  [batch A in progress]
+  (batches B and C are invisible)
+
+Final history (reconstructed by arrival order):
+  [prior history]
+  batch A (Discord) - arrived t=0
+  batch B (Bluesky) - arrived t=1
+  batch C (Connector) - arrived t=3
+```
+
+This is **implicit forking** - each batch gets isolated context, results merge back ordered by arrival time (via Snowflake IDs). The agent experiences it as fast sequential processing.
+
+### Deployment Configurations
+
+#### Home Server (Recommended for Power Users)
+

+**Cons**: Not always-on, no Discord/Bluesky when machine is off
+
+---
+
+## ACP Modes
+
+### Direct ACP (Local)
+
+Pattern runs as subprocess, editor spawns it directly:
+
+```bash
+# In editor's agent config
+{
+  "command": "pattern-acp",
+  "args": ["--constellation", "my-constellation", "--agent", "coder"]
+}
+```
+
+Pattern binary speaks ACP over stdio, has direct file access.
+
+### Proxied ACP (Remote via Connector)
+
+Editor connects to local connector daemon, which proxies to remote Pattern:
+
+```bash
+# Connector runs in background
+$ pattern-connector --daemon
+
+# Editor connects to connector's ACP socket
+{
+  "command": "pattern-connector",
+  "args": ["acp-proxy"]
+}
+```
+
+The connector:
+1. Receives ACP messages from editor via stdio
+2. Forwards to Pattern server via iroh
+3. Handles file/env requests from server
+4. Returns responses to editor
+
+### ACP Session Mapping
+
+| ACP Concept | Pattern Mapping |
+|-------------|-----------------|
+| `session/new` | Connect to existing agent/group (no new context created) |
+| `session/load` | Reconnect to same agent (mostly no-op) |
+| `session_id` | Connection handle, not conversation container |
+| `prompt` | Send message to agent, get streaming response |
+| `cancel` | Cancel current agent processing |
+
+Pattern's persistent memory means the agent maintains context across sessions. The "session" is just a connection, not a conversation boundary.
+
+---
+
+## Open Questions
+
+1. **Local/server sync** - For hybrid mode, how to sync constellation state?
+   - Shared database via network? 
+   - CAR-based sync?
+   - Conflict resolution for concurrent edits?
+
+2. **Rate limiting** - Different limits for different trust levels?
+   - Partner (CLI, ACP): no limits
+   - Conversant (Discord, Bluesky): per-user rate limits
+   - API: token bucket per API key
+
+3. **Group mode in ACP** - Should `session/set_mode` switch coordination patterns?
+   - Or expose as separate capability?
+
+4. **Connector auth in hybrid mode** - Local Pattern talking to server - same iroh auth flow?

+# Pattern v2.1: Constellation Forking (Future)
+
+> **Status**: Concept for future implementation. Not part of v2 initial release.
+
+## Overview
+
+Explicit forking and merging of constellations (or subsets thereof) for isolated work with optional reintegration.
+
+## Use Cases
+
+1. **Experimental work** - Try something risky without polluting main constellation history
+2. **Focused task** - Spin off agents for a specific project, less noise from other activity
+3. **Collaboration** - Fork, share with someone, merge their contributions back
+4. **Rollback** - If the fork goes badly, just discard it
+5. **Templates** - Fork a "clean" constellation as starting point for new projects
+
+## Fork Specification
+
+```rust
+pub struct ForkSpec {
+    /// Source constellation
+    pub source: ConstellationId,
+    
+    /// Which agents to include (None = all)
+    pub agents: Option<Vec<AgentId>>,
+    
+    /// How much history to bring
+    pub history: HistorySpec,
+    
+    /// Which memory blocks to copy
+    pub memory: MemorySpec,
+    
+    /// Include shared resources (folders, coordination state)?
+    pub include_shared: bool,
+}
+
+pub enum HistorySpec {
+    /// No history, just current memory state
+    None,
+    /// Last N messages per agent
+    Recent(usize),
+    /// Everything since timestamp
+    Since(DateTime<Utc>),
+    /// Full history
+    Full,
+}
+
+pub enum MemorySpec {
+    /// Core blocks only (persona, human)
+    CoreOnly,
+    /// Core + working
+    CoreAndWorking,
+    /// Everything including archival
+    Full,
+    /// Specific blocks by label
+    Specific(Vec<String>),
+}
+```
+
+## Merge Specification
+
+```rust
+pub struct MergeSpec {
+    /// Fork to merge from
+    pub source: ConstellationId,
+    
+    /// Target constellation
+    pub target: ConstellationId,
+    
+    /// What to merge
+    pub merge: MergeContent,
+    
+    /// Conflict resolution strategy
+    pub conflicts: ConflictResolution,
+}
+
+pub enum MergeContent {
+    /// Just memories (learnings), not conversation history
+    MemoriesOnly,
+    /// Memories + LLM-generated summary of what happened
+    MemoriesAndSummary,
+    /// Full history appended as delineated section
+    FullHistory,
+}
+
+pub enum ConflictResolution {
+    /// Fork wins (overwrite target)
+    PreferFork,
+    /// Target wins (keep target, discard fork conflicts)
+    PreferTarget,
+    /// Interactive resolution (prompt user)
+    Interactive,
+    /// Keep both versions (create separate blocks)
+    KeepBoth,
+}
+```
+
+## Memory Block Merge Semantics
+
+Loro CRDT enables automatic merging of memory blocks:
+
+```rust
+async fn merge_memory_block(
+    source_block: &MemoryBlock,
+    target_block: &MemoryBlock,
+) -> Result<MemoryBlock> {
+    // Loro documents can merge!
+    let mut merged_doc = target_block.document.clone();
+    merged_doc.merge(&source_block.document)?;
+    
+    // Result contains both histories, conflicts auto-resolved
+    Ok(MemoryBlock {
+        document: merged_doc,
+        ..target_block.clone()
+    })
+}
+```
+
+Merge rules:
+- **Block only in fork** → Copy to target
+- **Block only in target** → Keep as-is
+- **Block in both** → Loro CRDT merge (or interactive if structural conflict)
+
+## History Merge Options
+
+### Option 1: Append as Fork Session
+
+Clearly delineated in history:
+
+```
+[normal history]
+--- Fork: refactor-task (3 days) ---
+[fork history]
+--- End Fork ---
+[continues]
+```
+
+### Option 2: Summarize (Recommended Default)
+
+LLM generates summary of fork activity:
+
+```
+[normal history]
+[System: During "refactor-task" fork, coder refactored the memory system 
+ and entropy broke it into 12 subtasks. Key learnings were saved to archival.]
+[continues]
+```
+
+### Option 3: Memories Only
+
+Don't merge history at all, just memory block updates. Fork history is discarded.
+
+## CLI Interface
+
+```bash
+# Create fork
+$ pattern fork my-constellation --agents coder entropy --name refactor-task
+Created fork: refactor-task (2 agents, core+working memory, recent 100 messages)
+
+# Work in fork
+$ pattern chat --constellation refactor-task --agent coder
+
+# Check fork status
+$ pattern fork status refactor-task
+Fork: refactor-task
+Source: my-constellation
+Created: 2 days ago
+Agents: coder (847 new messages), entropy (234 new messages)
+Memory changes: 12 blocks modified, 3 new archival entries
+
+# Merge back
+$ pattern merge refactor-task --into my-constellation --summarize
+Merging fork...
+- 12 memory blocks merged (Loro CRDT)
+- 3 archival entries copied
+- Summary generated and inserted into history
+Done.
+
+# Or discard
+$ pattern fork delete refactor-task
+Deleted fork: refactor-task
+```
+
+## Dialect Integration
+
+Agents could fork/merge via dialect:
+
+```
+/fork agents coder entropy as "refactor-task"
+/fork status "refactor-task"
+/merge "refactor-task" summarize
+/fork delete "refactor-task"
+```
+
+This would require appropriate permissions - probably partner-only.
+
+## Implementation Considerations
+
+1. **Storage** - Fork creates new constellation DB (same as regular constellation)
+2. **Tracking** - Source constellation ID stored in fork metadata
+3. **Divergence tracking** - Record "fork point" for merge operations
+4. **Shared resources** - Folders, data sources need explicit handling
+5. **Coordination state** - Probably shouldn't be forked (or reset to clean state)
+
+## Relationship to Existing Concurrent Processing
+
+Pattern already handles concurrent message processing via batch isolation:
+
+```
+Timeline (actual):
+  t=0: msg A arrives, batch A starts processing
+  t=1: msg B arrives, batch B starts processing  
+  t=5: batch B completes (faster response)
+  t=8: batch A completes
+
+Agent's history (reconstructed):
+  [prior history]
+  batch A messages (t=0)  
+  batch B messages (t=1)
+```
+
+This is **implicit, automatic forking** for concurrent requests. The explicit forking described in this document is for **intentional, longer-lived divergence** with controlled merge back.
+
+## Open Questions
+
+1. **Nested forks** - Can you fork a fork?
+2. **Partial merge** - Merge some agents/blocks but not others?
+3. **Fork sharing** - Export fork for someone else to work on?
+4. **Long-lived forks** - At what point is it just a new constellation?
+5. **Sync during fork** - Should fork see updates from source? (Probably not - that's merge)

+# Pattern v2: Database Design
+
+## Overview
+
+Moving from SurrealDB to SQLite + sqlx. One database file per constellation provides physical isolation.
+
+## Why SQLite
+
+### Problems with SurrealDB
+
+1. **Immature ecosystem** - Constant API changes, missing features, weird edge cases
+2. **Live query limitations** - Can't use parameters in WHERE clauses, forces string interpolation
+3. **Type system friction** - `chrono::DateTime` vs `surrealdb::Datetime`, bracket-wrapped IDs
+4. **No row-level security in practice** - We couldn't get permissions working reliably
+5. **Custom entity macro** - We built a 1000+ line proc macro just to work around serialization issues
+6. **Debugging difficulty** - Hard to inspect what's actually in the database
+
+### SQLite Benefits
+
+1. **Battle-tested** - Decades of production use, known behavior
+2. **Extensions for everything** - sqlite-vec for vectors, FTS5 for full-text search
+3. **One file = one database** - Natural isolation per constellation
+4. **sqlx is solid** - Compile-time checked queries, good async support
+5. **Easy debugging** - Can open in any SQLite browser
+6. **Portable** - Database files are self-contained, easy backup/restore
+
+## Architecture
+
+### One Database Per Constellation
+
+```
+data/
+├── constellations/
+│   ├── {constellation_id}/

+```
+
+**Benefits:**
+- No cross-constellation data leaks possible at DB level
+- SQLite's single-writer is fine (one constellation = sequential operations)
+- Easy to backup/restore/migrate individual constellations
+- Can run multiple constellations in parallel (separate DB connections)
+
+### Global Database
+
+Small database for cross-constellation concerns:
+
+```sql
+-- User accounts (for server mode)
+CREATE TABLE users (

+    email TEXT UNIQUE,
+    password_hash TEXT,  -- NULL for OAuth-only users
+    created_at TEXT NOT NULL,
+    updated_at TEXT NOT NULL
+);
+
+-- OAuth identities
+CREATE TABLE user_identities (
+    id TEXT PRIMARY KEY,
+    user_id TEXT NOT NULL,
+    provider TEXT NOT NULL,  -- 'atproto', 'discord', etc.
+    provider_id TEXT NOT NULL,
+    access_token TEXT,
+    refresh_token TEXT,
+    expires_at TEXT,
+    created_at TEXT NOT NULL,
+    UNIQUE(provider, provider_id),
+    FOREIGN KEY (user_id) REFERENCES users(id)
+);
+
+-- Constellation registry

+
+### Connection Management
+
+```rust
+use sqlx::sqlite::{SqlitePool, SqlitePoolOptions};
+
+pub struct ConstellationDb {
+    pool: SqlitePool,
+    constellation_id: String,
+}
+
+impl ConstellationDb {
+    pub async fn open(path: &Path) -> Result<Self> {
+        let pool = SqlitePoolOptions::new()
+            .max_connections(5)  // SQLite is single-writer anyway
+            .connect(&format!("sqlite:{}?mode=rwc", path.display()))
+            .await?;
+        
+        // Run migrations
+        sqlx::migrate!("./migrations")
+            .run(&pool)
+            .await?;
+        
+        // Load sqlite-vec extension
+        sqlx::query("SELECT load_extension('vec0')")
+            .execute(&pool)
+            .await?;
+        
+        Ok(Self { pool, constellation_id })
+    }
+    
+    pub fn pool(&self) -> &SqlitePool {
+        &self.pool
+    }
+}
+```
+
+### Transactions
+
+```rust
+pub async fn create_agent_with_default_blocks(
+    db: &ConstellationDb,
+    agent: &Agent,
+) -> Result<()> {
+    let mut tx = db.pool().begin().await?;
+    
+    // Create agent
+    sqlx::query!(/* ... */)
+        .execute(&mut *tx)
+        .await?;

+            .execute(&mut *tx)
+            .await?;
+    }
+    
+    tx.commit().await?;
+    Ok(())
+}
+```
+
+## Migration Strategy
+
+### From v1 SurrealDB
+
+1. Export constellation to CAR file (v1 format)
+2. Parse CAR, extract entities
+3. Transform to v2 schema (agent_id on memories, etc.)
+4. Import into fresh SQLite database
+5. Generate Loro documents for memory blocks
+
+See [v2-migration-path.md](./v2-migration-path.md) for details.
+
+### Schema Migrations
+
+Using sqlx migrations in `migrations/` directory:
+
+```
+migrations/
+├── 20250101000000_initial.sql
+├── 20250102000000_add_task_embeddings.sql
+└── ...
+```
+
+## Performance Considerations
+
+### Indexes
+
+Key indexes for common query patterns:
+
+```sql
+-- Agent lookups
+CREATE INDEX idx_agents_name ON agents(name);
+CREATE INDEX idx_agents_status ON agents(status);
+
+-- Memory block lookups
+CREATE INDEX idx_memory_blocks_agent ON memory_blocks(agent_id);
+CREATE INDEX idx_memory_blocks_type ON memory_blocks(agent_id, block_type);
+
+-- Message queries (most common)
+CREATE INDEX idx_messages_agent_position ON messages(agent_id, position DESC);
+CREATE INDEX idx_messages_batch ON messages(batch_id);
+```
+
+### Blob Storage
+
+Loro snapshots are stored as BLOBs. For large documents:
+
+```sql
+-- Consider separate table for large blobs
+CREATE TABLE large_blobs (
+    id TEXT PRIMARY KEY,
+    data BLOB NOT NULL
+);
+
+-- Reference from memory_blocks
+ALTER TABLE memory_blocks ADD COLUMN large_blob_id TEXT REFERENCES large_blobs(id);
+```
+
+### Connection Pooling
+
+SQLite with WAL mode handles concurrent reads well:
+
+```rust
+SqlitePoolOptions::new()
+    .max_connections(10)  // Readers can be parallel
+    .connect("sqlite:pattern.db?mode=rwc&_journal_mode=WAL")
+```
+
+## Design Decisions
+
+### Embeddings
+
+**Decision**: Support multiple embedding models, pursue local model as default.
+
+- Store embedding dimension in config per constellation/folder
+- Create vec tables dynamically based on configured dimension
+- Default to a local model (e.g., `all-MiniLM-L6-v2` at 384 dims) to avoid cloud costs
+- Cloud embeddings (OpenAI, Google) available as opt-in for higher quality
+- This matches current v1 approach but with local-first default
+
+### Blob Compression & Loro Snapshots
+
+**Decision**: Compress large snapshots, periodic checkpoints, incremental updates.
+
+Strategy:
+1. **Frequent ops**: Store Loro update deltas (small, fast)
+2. **Periodic checkpoints**: Full document snapshot that acts as new root
+   - Triggered by: update count threshold, total update size, or time interval
+   - Old updates before checkpoint can be pruned
+3. **Compression**: zstd compress snapshots over N bytes (e.g., 10KB)
+4. **History**: Checkpoint acts as "shallow clone" point - history before it is summarized/discarded
+
+```rust
+pub struct LoroStorageConfig {
+    /// Compress snapshots larger than this
+    pub compression_threshold_bytes: usize,  // default: 10KB
+    /// Checkpoint after this many updates
+    pub checkpoint_update_count: usize,      // default: 100
+    /// Checkpoint if updates exceed this size
+    pub checkpoint_update_size: usize,       // default: 50KB
+    /// Maximum time between checkpoints
+    pub checkpoint_interval: Duration,       // default: 1 hour
+}
+```
+
+### Backup Strategy
+
+**Decision**: CAR files for cold storage/migration, SQLite backup API for hot backups.
+
+- **CAR exports**: Cross-version portable, human-reviewable structure, used for migration and archival
+- **SQLite backups**: Fast, consistent snapshots for disaster recovery
+- **Recommendation**: Automated SQLite backups (daily), manual CAR exports for major milestones
+
+```bash
+# Hot backup (fast, for disaster recovery)
+pattern-cli backup --constellation "MyConstellation" -o backup.db
+
+# Cold export (portable, for migration/archival)  
+pattern-cli export constellation --name "MyConstellation" -o archive.car
+```
+
+### sqlite-vec
+
+**Decision**: Bundle sqlite-vec, explicit migration via CLI.
+
+- sqlite-vec compiled and bundled with pattern binaries
+- On startup, check schema version against expected
+- If outdated, refuse to run and prompt: `pattern-cli db migrate`
+- Migrations are explicit user action, not automatic (safety)
+
+### Multi-Process Access
+
+**Decision**: Single canonical writer process ("server"), one DB per constellation, concurrency via threading.
+
+Architecture:
+```
+┌─────────────────────────────────────────────────────────────┐
+│                    Pattern Server Process                   │
+├─────────────────────────────────────────────────────────────┤
+│  ┌─────────────┐  ┌─────────────┐  ┌─────────────┐        │
+│  │Constellation│  │Constellation│  │Constellation│        │
+│  │  Thread A   │  │  Thread B   │  │  Thread C   │        │
+│  │             │  │             │  │             │        │
+│  │ agents.db   │  │ agents.db   │  │ agents.db   │        │
+│  │ (exclusive) │  │ (exclusive) │  │ (exclusive) │        │
+│  └─────────────┘  └─────────────┘  └─────────────┘        │
+├─────────────────────────────────────────────────────────────┤
+│  Shared: LLM API clients, config, global.db (user accounts) │
+└─────────────────────────────────────────────────────────────┘
+```
+
+- Each constellation gets its own thread with exclusive DB access
+- No SQLite concurrency concerns - single writer per DB
+- LLM API is the bottleneck (99.9999% of the time), not SQLite
+- CLI in "server mode" fills this role currently; explicit server binary later
+- CLI can also run standalone for single-constellation local use
+
+### Vacuum Schedule
+
+**Decision**: Manual trigger, with recommendations.
+
+- `pattern-cli db vacuum --constellation "MyConstellation"`
+- Recommend after: migration, bulk deletes, major archival operations
+- Could add `--auto-vacuum` flag for background maintenance mode
+- SQLite's auto_vacuum pragma is an option but has tradeoffs
+
+## Memory Block Delta Storage (Detailed Design)
+
+### Overview
+
+Incremental update storage for memory blocks to reduce write amplification. The DB layer (pattern_db) stores deltas and provides query primitives; the application layer (pattern_core) handles Loro operations and in-memory caching.
+
+**Key principle**: pattern_db remains Loro-agnostic. It stores blobs and provides efficient "updates since X" queries. pattern_core owns deserialization, merging, and in-memory caching of hot blocks.
+
+### Data Flow
+
+**Write path**:
+1. pattern_core applies update to in-memory Loro doc
+2. Extracts delta blob from Loro
+3. Calls `store_update(block_id, delta, source)`
+4. pattern_db assigns next seq, persists update
+
+**Read path** (cache miss):
+1. `get_checkpoint_and_updates(block_id)` returns checkpoint + all pending updates
+2. pattern_core deserializes checkpoint, applies updates in seq order
+3. Caches result keyed by block_id
+
+**Read path** (cache hit):
+1. `get_updates_since(block_id, last_seq)` returns new updates only
+2. Apply to cached doc, update last_seq
+
+### Schema (replaces basic sketch in Memory Tables section)
+
+**New table** - `memory_block_updates`:
+
+```sql
+CREATE TABLE memory_block_updates (
+    id INTEGER PRIMARY KEY AUTOINCREMENT,
+    block_id TEXT NOT NULL REFERENCES memory_blocks(id) ON DELETE CASCADE,
+    seq INTEGER NOT NULL,
+    update_blob BLOB NOT NULL,
+    byte_size INTEGER NOT NULL,
+    source TEXT,  -- 'agent', 'sync', 'migration', 'manual'
+    created_at TEXT NOT NULL
+);
+CREATE UNIQUE INDEX idx_updates_block_seq ON memory_block_updates(block_id, seq);
+```
+
+**Additions to `memory_blocks`**:
+
+```sql
+ALTER TABLE memory_blocks ADD COLUMN frontier BLOB;
+ALTER TABLE memory_blocks ADD COLUMN last_seq INTEGER NOT NULL DEFAULT 0;
+```
+
+**Additions to `memory_block_checkpoints`**:
+
+```sql
+ALTER TABLE memory_block_checkpoints ADD COLUMN frontier BLOB;
+```
+
+### Query API (pattern_db)
+
+```rust
+// Store a new update, returns assigned seq
+async fn store_update(pool, block_id, update_blob, source) -> DbResult<i64>;
+
+// Get checkpoint + all pending updates for reconstruction
+async fn get_checkpoint_and_updates(pool, block_id) -> DbResult<(Option<Checkpoint>, Vec<Update>)>;
+
+// Get only updates after a given seq (for cache refresh)
+async fn get_updates_since(pool, block_id, after_seq) -> DbResult<Vec<Update>>;
+
+// Check if updates exist without fetching them
+async fn has_updates_since(pool, block_id, after_seq) -> DbResult<bool>;
+
+// Atomic consolidation: delete updates, store new checkpoint
+async fn consolidate_checkpoint(pool, block_id, new_snapshot, new_frontier, up_to_seq) -> DbResult<()>;
+
+// Stats for consolidation decisions
+async fn get_pending_update_stats(pool, block_id) -> DbResult<UpdateStats>;  // count, total_bytes
+```
+
+### Edge Cases & Considerations
+
+**Concurrent writes**: SQLite's single-writer model handles this. `seq` assignment is atomic via `last_seq` update in same transaction as insert.
+
+**Crash recovery**: Updates are durable once `store_update` returns. Worst case: checkpoint is stale, but updates rebuild correct state.
+
+**Consolidation race**: `consolidate_checkpoint` uses `up_to_seq` to only delete updates that were actually merged. New updates arriving during merge are preserved.
+
+**Empty state**: New blocks start with `last_seq = 0`, no checkpoint. First write can be either a full snapshot (checkpoint) or an update—pattern_core decides.
+
+**Orphaned updates**: `ON DELETE CASCADE` cleans up updates when block is deleted.
+
+**Multi-writer**: Rare case (shared blocks). Loro handles merge conflicts; DB just stores the deltas from each writer with their own seqs.
+
+### Out of Scope (for pattern_db)
+
+- **Update compression**: Store raw deltas; Loro's format is already compact.
+- **Automatic consolidation triggers**: pattern_core owns policy; DB just provides primitives.
+- **In-memory caching**: Lives in pattern_core, not pattern_db.
+
+### Migration Path
+
+1. Add migration `0004_memory_updates.sql` with new table and column additions
+2. Existing blocks have `frontier = NULL`, `last_seq = 0` (no pending updates)
+3. No data migration needed—existing `loro_snapshot` remains valid as checkpoint
+
+## Remaining Open Questions
+
+1. **Default local embedding model** - Which specific model to bundle/recommend?
+   - `all-MiniLM-L6-v2` (384 dims, fast, decent quality)
+   - `bge-small-en-v1.5` (384 dims, better quality)
+   - `nomic-embed-text-v1` (768 dims, good quality, larger)
+
+2. **Checkpoint history retention** - How many checkpoints to keep?
+   - Keep last N checkpoints for rollback?
+   - Or just current + one previous?
+
+3. **Server process management** - Systemd service? Docker? Just CLI?
+   - For local use: CLI is fine
+   - For always-on: need proper service management

+
+---
+
+## Fuzzy Verb Matching
+
+### Matching Tiers
+
+The matcher tries these in order, returning the first confident match:
+
+```
+1. Exact match (canonical or alias)
+2. Case-insensitive exact match
+3. Morphological variants (plurals, tenses, spellings)
+4. Levenshtein distance (typos)
+5. Phonetic similarity (soundex/metaphone)
+6. [Optional] Semantic similarity (embeddings)
+```
+
+### Tier 1-2: Exact Matching
+
+```rust
+fn exact_match(input: &str, verbs: &[VerbSpec]) -> Option<&VerbSpec> {
+    let input_lower = input.to_lowercase();
+    
+    for verb in verbs {
+        if verb.canonical == input || verb.canonical.eq_ignore_ascii_case(input) {
+            return Some(verb);
+        }
+        for alias in &verb.aliases {
+            if *alias == input || alias.eq_ignore_ascii_case(input) {
+                return Some(verb);
+            }
+        }
+    }
+    None
+}
+```
+
+### Tier 3: Morphological Variants
+
+Handle common English variations without needing explicit aliases:
+
+```rust
+pub struct MorphologicalMatcher {
+    // Irregular forms we need to know about
+    irregulars: HashMap<&'static str, &'static str>,
+}
+
+impl MorphologicalMatcher {
+    pub fn new() -> Self {
+        let mut irregulars = HashMap::new();
+        // Irregular verbs relevant to our domain
+        irregulars.insert("sent", "send");
+        irregulars.insert("told", "tell");
+        irregulars.insert("found", "find");
+        irregulars.insert("forgot", "forget");
+        irregulars.insert("wrote", "write");
+        irregulars.insert("thought", "think");
+        Self { irregulars }
+    }
+    
+    pub fn normalize(&self, word: &str) -> String {
+        let word = word.to_lowercase();
+        
+        // Check irregulars first
+        if let Some(base) = self.irregulars.get(word.as_str()) {
+            return base.to_string();
+        }
+        
+        // Regular patterns
+        let normalized = word
+            // -ing: searching -> search
+            .strip_suffix("ing")
+            .map(|s| {
+                // Handle doubling: stopping -> stop
+                if s.len() > 2 && s.chars().last() == s.chars().nth(s.len() - 2) {
+                    &s[..s.len()-1]
+                } else if s.ends_with("e") {
+                    // making -> make (we stripped 'ing', add back 'e')
+                    return format!("{}e", s);
+                } else {
+                    s
+                }
+            })
+            // -ed: searched -> search
+            .or_else(|| word.strip_suffix("ed").map(|s| {
+                if s.ends_with("i") {
+                    // tried -> try
+                    format!("{}y", &s[..s.len()-1])

+## Action Detection & Execution
+
+### Detection Rules
+
+Actions are detected anywhere in agent output, but only executed under specific conditions.
+
+```rust
+pub struct DetectedAction {
+    pub action: ParsedAction,
+    pub span: Span,           // position in message
+    pub is_trailing: bool,    // no non-whitespace after
+    pub has_do_marker: bool,  // prefixed with /do
+}
+
+pub struct ActionDetector {
+    sigil: char,              // '/'
+    do_marker: &'static str,  // "do"
+}
+
+impl ActionDetector {
+    pub fn detect_all(&self, message: &str) -> Vec<DetectedAction> {
+        // Find all /verb patterns in message
+        // Mark each with position, trailing status, /do presence
+    }
+    
+    pub fn executable_actions(&self, message: &str) -> Vec<ParsedAction> {
+        self.detect_all(message)
+            .into_iter()
+            .filter(|a| should_execute(a, message))
+            .map(|a| a.action)
+            .collect()
+    }
+}
+```
+
+### Execution Decision
+
+```rust
+pub fn should_execute(
+    action: &DetectedAction,
+    message: &str,
+) -> bool {
+    // Must be trailing or explicitly marked with /do
+    if !action.is_trailing && !action.has_do_marker {
+        return false;
+    }
+    
+    // Check for reconsideration in text after the action
+    let text_after = &message[action.span.end..];
+    if has_reconsideration(text_after) {
+        return false;
+    }
+    
+    true
+}
+
+fn has_reconsideration(text: &str) -> bool {
+    const PATTERNS: &[&str] = &[
+        "actually",
+        "wait", 
+        "never mind",
+        "nevermind",
+        "scratch that",
+        "ignore that",
+        "don't need",
+        "won't need", 
+        "shouldn't",
+        "hold on",
+        "let me think",
+        "on second thought",
+        "no,",
+        "nope",
+        "nah",
+        "forget that",
+        "disregard",
+        "not necessary",
+        "don't bother",
+    ];
+    
+    let lower = text.to_lowercase();
+    PATTERNS.iter().any(|p| lower.contains(p))
+}
+```
+
+### Examples
+
+```
+# EXECUTED - trailing action, no reconsideration
+Let me check what we discussed.
+/recall project deadlines
+
+# NOT EXECUTED - reconsideration after
+Let me check that.
+/recall project deadlines
+Actually wait, you just told me. Never mind.
+
+# EXECUTED - explicit /do marker
+/do /recall project deadlines
+I'll keep talking while that runs.
+
+# NOT EXECUTED - mid-message, no marker
+I could /recall the notes but let's think first...
+
+# NOT EXECUTED - /do but then reconsideration
+/do /recall project deadlines
+Hmm, actually scratch that, wrong label.
+
+# EXECUTED - multiple trailing actions
+Let me gather some context.
+/recall project notes
+/search conversations about deadline

+
+### Current vs Future Streaming Behavior
+
+**Current (no streaming):**
+- Full message available before any execution
+- Detect all actions, filter by rules, execute survivors
+- Simple and safe
+
+**Future (with streaming):**
+- Partial responses shown to user as they generate
+- Execution still waits for message completion by default
+- Exception: `/do` + safe action subset + token window
+
+```rust

+        confirmation_window: usize,  // e.g., 50 tokens
+        /// Only these action types allowed
+        allowed_verbs: HashSet<Verb>,
+    },
+}
+
+/// Actions safe for stream-execution (no side effects, cancellable)
+pub fn streaming_safe_verbs() -> HashSet<Verb> {
+    hashset! {
+        Verb::Recall,   // read-only recall (not insert/delete)
+        Verb::Search,
+        Verb::Calc,
+    }
+}
+
+/// Full stream-execution rules (future)
+pub async fn maybe_stream_execute(
+    action: &DetectedAction,
+    token_stream: &mut TokenStream,
+    timing: ExecutionTiming,
+) -> Option<ActionResult> {

+        
+        ExecutionTiming::Streaming { confirmation_window, allowed_verbs } => {
+            // Must have explicit /do marker
+            if !action.has_do_marker {
+                return None;
+            }
+            
+            // Must be in safe subset

+            
+            // Must be read-only variant of the verb

+            }
+            
+            // Wait for confirmation window
+            let mut tokens_seen = 0;
+            while tokens_seen < confirmation_window {
+                match token_stream.try_next().await {
+                    Some(token) => {
+                        if has_reconsideration(&token) {
+                            return None;  // cancelled
+                        }
+                        tokens_seen += 1;

+                    None => break,  // stream ended
+                }
+            }
+            
+            // Window passed, no reconsideration - execute
+            Some(execute(action.action.clone()).await)
+        }
+    }
+}

+# Pattern v2: Memory System Design
+
+## Research Summary
+
+### Loro CRDT Library
+
+Loro is a Rust-native CRDT library with first-class support for:
+
+**Data Types:**
+- `LoroText` - Rich text with Fugue algorithm (minimizes interleaving)
+- `LoroList` - Ordered list with move support
+- `LoroMovableList` - List where items can be moved
+- `LoroMap` - Last-write-wins map
+- `LoroTree` - Hierarchical tree with move support
+- `LoroCounter` - Numeric counter
+
+**Key Features:**
+- **Snapshot + Updates model** - Full snapshots for periodic saves, delta updates for frequent saves
+- **Time Travel** - `doc.checkout(frontiers)` jumps to any version
+- **Version Vectors** - Track what each peer has seen
+- **Shallow Snapshots** - Like git shallow clone, archive old history
+- **JSONPath queries** - Query document structure
+- **Built-in checksums** - Validates imports, rejects corrupted data
+
+**Persistence Pattern:**
+```rust
+// Periodic: export full snapshot
+let snapshot = doc.export(ExportMode::Snapshot);
+store_to_db(snapshot);
+
+// Frequent: export delta updates
+let updates = doc.export(ExportMode::Updates { from: last_version });
+append_to_log(updates);
+
+// Load: import snapshot + all updates
+let doc = LoroDoc::new();
+doc.import(snapshot);
+for update in updates {
+    doc.import(update);
+}
+```
+
+**Detached State Consideration:**
+When you `checkout()` to a historical version, the document becomes read-only. Must call `attach()` to return to editing. This is intentional - you're viewing history, not rewriting it.
+
+### Letta Memory Blocks
+
+Letta's memory system uses named blocks with clear semantics:
+
+**Block Structure:**
+- `label` - Unique identifier (e.g., "human", "persona", "organization")
+- `description` - Crucial for LLM to understand purpose
+- `value` - The actual content
+- `limit` - Character limit
+- `read_only` - Whether agent can modify
+
+**Key Design Principles:**
+1. **Description is critical** - The LLM uses the description to understand what to store
+2. **Labels are semantic** - "human", "persona", "scratchpad", "organization"
+3. **Blocks are shareable** - Multiple agents can attach to the same block
+4. **Always in context** - No retrieval needed, blocks are always visible
+5. **Agent-managed** - Agents autonomously organize based on labels
+
+**Default Descriptions:**
+- `persona`: "Stores details about your current persona, guiding how you behave and respond"
+- `human`: "Stores key details about the person you are conversing with"
+
+**Use Cases from Letta:**
+- Tool usage guidelines (avoid past mistakes)
+- Working memory / scratchpad
+- Mirror external state (user's current document)
+- Read-only policies shared across agents
+- Multi-agent coordination (watch subagent result blocks)
+- Emergent behaviour (`performance_tracking`, `emotional_state`)
+
+### sqlite-vec
+
+Vector search extension for SQLite:
+
+**Features:**
+- Virtual table: `CREATE VIRTUAL TABLE vec_items USING vec0(embedding float[384])`
+- KNN queries with `match` and `order by distance`
+- Supports float, int8, and binary vectors
+- Metadata columns, partition keys, auxiliary columns
+- Pure C, no dependencies, runs anywhere SQLite runs
+
+**Usage:**
+```sql
+CREATE VIRTUAL TABLE vec_memories USING vec0(
+  embedding float[384],
+  +memory_id TEXT,      -- metadata column
+  +block_label TEXT     -- for filtering
+);
+
+-- KNN query
+SELECT memory_id, distance
+FROM vec_memories
+WHERE embedding MATCH ?
+  AND block_label = 'archival'
+ORDER BY distance
+LIMIT 10;
+```
+
+---
+
+## Existing v1 Tool Structure (Preserving)
+
+The current tools are well-designed and should be preserved with minimal changes:
+
+### `context` Tool
+Manages **Core** and **Working** memory - blocks always/usually in context:
+- `append` - Add content to a block
+- `replace` - Find and replace content within a block
+- `archive` - Move working memory to archival (frees context space)
+- `load` - Bring archival memory into working memory
+- `swap` - Exchange working and archival blocks
+
+### `recall` Tool
+Manages **Archival** memory - long-term storage not in context:
+- `insert` - Create new archival entry
+- `append` - Add to existing archival entry
+- `read` - Retrieve by label
+- `delete` - Remove archival entry
+
+### `search` Tool
+Unified search across domains:
+- `archival_memory` - Search archival blocks
+- `conversations` - Search message history
+- `constellation_messages` - Search across all agents in constellation
+- `all` - Search everything
+
+**Key insight:** The tool interface is solid. What needs to change is the storage backend and the isolation model.
+
+### What to Preserve
+- Tool names and basic operations
+- Core/Working/Archival distinction
+- Search across multiple domains
+- Permission system (ACL checks)
+
+### What to Change/Improve
+- **Storage backend** - SQLite + Loro instead of SurrealDB + DashMap
+- **Ownership model** - Agent-scoped instead of User-scoped
+- **Versioning** - Loro gives us history/rollback for free
+- **Descriptions** - Add Letta-style descriptions to guide LLM usage
+- **Templates** - Structured schemas for common block patterns
+- **Rolling logs** - System-maintained logs the agent doesn't manage
+- **Archival entries** - Separate table from blocks for fine-grained storage
+- **Search** - sqlite-vec for vectors, FTS5 for full-text (replacing SurrealDB's BM25)
+
+---
+
+## v2 Memory Architecture
+
+### Core Principles
+
+1. **Loro documents as memory blocks** - Each memory block is a Loro document
+2. **Agent-scoped, not user-scoped** - Memories belong to agents, not users (KEY CHANGE from v1)
+3. **Labels with semantic descriptions** - Following Letta's pattern
+4. **Versioned by default** - Every change tracked via Loro
+5. **No in-memory cache** - SQLite + Loro documents are the source of truth
+6. **Preserve tool interface** - Same tools, new backend
+
+### Memory Block Types
+
+```rust
+pub enum MemoryBlockType {
+    /// Always in context, critical for agent identity
+    /// Examples: persona, human, system guidelines
+    Core,
+    
+    /// Working memory, can be swapped in/out based on relevance
+    /// Examples: scratchpad, current_task, session_notes
+    Working,
+    
+    /// Long-term storage, NOT in context by default
+    /// Retrieved via recall/search tools using semantic search
+    /// Examples: past conversations, learned facts, reference material
+    Archival,
+    
+    /// System-maintained logs (read-only to agent)
+    /// Recent entries shown in context, older entries searchable
+    /// Examples: tool_execution_log, event_log, compression_summaries
+    Log,
+}
+```
+
+### Context Inclusion Model
+
+**Always in context:**
+- `Core` blocks - Always included, agent identity depends on these
+- `Log` blocks - Recent N entries included (configurable)
+
+**Available via tool call:**
+- `Archival` blocks - Agent uses `recall` or `search` tools to retrieve
+- `Working` blocks marked as swapped out
+
+**The key insight:** Core memory is the agent's "working memory" that's always visible. Archival memory is "long-term storage" that requires explicit retrieval. This mirrors how MemGPT/Letta works - the agent has limited context but can search its full history.

+### Block Schema
+
+```rust
+pub struct MemoryBlock {
+    /// Unique identifier
+    pub id: MemoryBlockId,
+    
+    /// Owning agent (NOT user - this is the key change from v1)
+    pub agent_id: AgentId,
+    
+    /// Semantic label: "persona", "human", "scratchpad", etc.
+    pub label: String,
+    
+    /// Description for the LLM (critical for proper usage)
+    pub description: String,
+    
+    /// Block type determines context inclusion behavior
+    pub block_type: MemoryBlockType,
+    
+    /// Character limit for the block
+    pub limit: usize,
+    
+    /// Whether the agent can modify this block
+    pub read_only: bool,
+    
+    /// The Loro document containing the block content
+    /// Stored as snapshot blob in SQLite
+    pub document: LoroDoc,
+    
+    /// Embedding for semantic search (archival blocks)
+    pub embedding: Option<Vec<f32>>,
+    
+    /// Creation timestamp
+    pub created_at: DateTime<Utc>,
+    
+    /// Last modified timestamp
+    pub updated_at: DateTime<Utc>,
+}
+```
+
+### Loro Document Structure for Blocks
+
+Each memory block's `LoroDoc` contains:
+
+```rust
+// For simple text blocks (persona, human)
+doc.get_text("content")
+
+// For structured blocks (could support complex data)
+doc.get_map("metadata")
+doc.get_text("content")
+doc.get_list("entries")  // for log-style blocks
+```
+
+### Rolling Logs (System-Maintained)
+
+New concept: blocks that the system appends to, agent observes but doesn't manage:
+
+```rust
+pub struct RollingLog {
+    /// Uses LoroList under the hood
+    entries: LoroList,
+    
+    /// Max entries before oldest are pruned
+    max_entries: usize,
+    
+    /// Entry schema
+    entry_type: LogEntryType,
+}
+
+pub enum LogEntryType {
+    /// Tool calls and results
+    ToolExecution { tool: String, result: String, timestamp: DateTime<Utc> },
+    
+    /// Significant events
+    Event { event_type: String, details: String, timestamp: DateTime<Utc> },
+    
+    /// Summaries from compression
+    ContextSummary { summary: String, messages_summarized: usize, timestamp: DateTime<Utc> },
+}
+```
+
+The agent sees a read-only view of recent entries in context, but doesn't have to manage the log.
+
+### Templated Memory Blocks
+
+Pre-defined block schemas for common patterns:
+
+```rust
+pub enum BlockTemplate {
+    /// Agent's personality and behavior
+    Persona {
+        name: String,
+        traits: Vec<String>,
+        style: String,
+        guidelines: String,
+    },
+    
+    /// Information about the human
+    Human {
+        name: Option<String>,
+        preferences: Vec<String>,
+        context: String,
+    },
+    
+    /// Working scratchpad
+    Scratchpad {
+        current_task: Option<String>,
+        notes: String,
+    },
+    
+    /// Shared organizational info (read-only)
+    Organization {
+        name: String,
+        policies: String,
+    },
+    
+    /// Custom free-form
+    Custom {
+        schema: Option<serde_json::Value>,
+    },
+}
+```
+
+Templates generate the description automatically and can validate content.
+
+### Versioning & Rollback
+
+Thanks to Loro, every memory block has full history:
+
+```rust
+impl MemoryBlock {
+    /// Get all versions of this block
+    pub fn get_history(&self) -> Vec<MemoryVersion> {
+        let changes = self.document.getAllChanges();
+        // Convert to version summaries
+    }
+    
+    /// View block at a specific version (read-only)
+    pub fn checkout(&self, version: Frontiers) -> MemoryBlockView {
+        let mut doc = self.document.clone();
+        doc.checkout(version);
+        MemoryBlockView { doc }
+    }
+    
+    /// Roll back to a previous version (creates new change)
+    pub fn rollback_to(&mut self, version: Frontiers) {
+        let old_content = self.checkout(version).content();
+        self.document.attach(); // Return to head
+        // Set content to old value - this creates a new change
+        self.document.get_text("content").delete(0, current_len);
+        self.document.get_text("content").insert(0, &old_content);
+    }
+}
+```
+
+### Shared Blocks Between Agents
+
+**Key distinction from v1:** Sharing is now *explicit and intentional*, not accidental.
+
+v1 problem: Memories owned by User, so any agent in the constellation could accidentally overwrite another agent's "persona" block if they used the same label.
+
+v2 solution: Memories owned by Agent by default. Sharing requires explicit attachment.
+
+```rust
+/// A memory block can be shared with other agents via explicit attachment
+pub struct SharedBlockAttachment {
+    /// The block being shared (has a primary owner agent)
+    pub block_id: MemoryBlockId,
+    
+    /// Agent gaining access (not the owner)
+    pub agent_id: AgentId,
+    
+    /// What this agent can do with the block
+    pub access: SharedAccess,
+    
+    /// When the attachment was created
+    pub attached_at: DateTime<Utc>,
+}
+
+pub enum SharedAccess {
+    /// Can read but not modify
+    ReadOnly,
+    /// Can append but not overwrite
+    AppendOnly,
+    /// Full read/write access
+    ReadWrite,
+}
+```
+
+**How sharing works:**
+
+```rust
+// Agent A creates a block (A owns it)
+let block = memory_store.create_block(
+    &agent_a_id,
+    "shared_task_board",
+    "Shared task tracking for the constellation",
+    MemoryBlockType::Working,
+    "## Tasks\n- [ ] Initial task",
+).await?;
+
+// Explicitly share with Agent B (read-write)
+memory_store.share_block(
+    &block.id,
+    &agent_b_id,
+    SharedAccess::ReadWrite,
+).await?;
+
+// Share with Agent C (read-only)
+memory_store.share_block(
+    &block.id,
+    &agent_c_id,
+    SharedAccess::ReadOnly,
+).await?;
+```
+
+**Constellation-level shared blocks:**
+
+For blocks that should be visible to ALL agents in a constellation:
+
+```rust
+/// Special owner_id indicating constellation-level ownership
+pub const CONSTELLATION_OWNER: &str = "_constellation_";
+
+// Create a constellation-wide block
+let org_block = memory_store.create_constellation_block(
+    "organization",
+    "Read-only information about the organization and its policies",
+    MemoryBlockType::Core,
+    "Organization: Pattern Project\nPolicies: Be helpful, be honest...",
+    SharedAccess::ReadOnly,  // All agents get this access level
+).await?;
+```
+
+**Use cases:**
+- `organization` - Read-only policies shared across all agents
+- `partner_profile` - Info about the human, all agents can read, one can write
+- `task_board` - Shared task tracking, multiple agents can write
+- `handoff_notes` - Agent A writes context for Agent B during handoffs
+
+**What this prevents:**
+- Agent A's "persona" accidentally overwriting Agent B's "persona" (different blocks now)
+- New agents inheriting memories they shouldn't have
+- Confusion about which agent's data is which

+
+## Agent Memory Tools
+
+The agent interacts with memory through built-in tools:
+
+### Core Memory Tools
+
+```rust
+/// Update a core memory block
+/// Only works on Core/Working blocks the agent has write access to
+pub struct CoreMemoryUpdate {
+    /// Which block to update: "persona", "human", etc.
+    pub label: String,
+    /// New content (replaces existing)
+    pub content: String,
+}
+
+/// Append to a core memory block (useful for incremental updates)
+pub struct CoreMemoryAppend {
+    pub label: String,
+    pub content: String,
+}
+```
+
+### Archival Memory Tools
+
+```rust
+/// Search archival memory using semantic similarity
+/// Returns relevant entries from long-term storage
+pub struct ArchivalSearch {
+    /// Natural language query
+    pub query: String,
+    /// Max results to return
+    pub limit: Option<usize>,
+}
+
+/// Insert new content into archival memory
+/// Use for facts worth remembering long-term
+pub struct ArchivalInsert {
+    /// Content to store
+    pub content: String,
+    /// Optional structured metadata
+    pub metadata: Option<serde_json::Value>,
+}
+```
+
+### Recall Tool
+
+```rust
+/// Recall searches BOTH conversation history AND archival memory
+/// More comprehensive than archival_search alone
+pub struct Recall {
+    /// Natural language query
+    pub query: String,
+    /// Max results
+    pub limit: Option<usize>,
+}
+```
+
+### Tool Descriptions for LLM
+
+These descriptions help the agent understand when to use each tool:
+
+```
+core_memory_update: Update your core memory blocks (persona, human, etc.). 
+Use this to modify persistent information about yourself or the person 
+you're talking to. Changes are immediately reflected in your context.
+
+core_memory_append: Add content to an existing core memory block without 
+replacing it. Useful for incrementally building up information.
+
+archival_search: Search your long-term archival memory using semantic 
+similarity. Use this when you need to recall specific facts, past 
+conversations, or reference material that isn't in your current context.
+
+archival_insert: Save important information to your archival memory for 
+future reference. Use this for facts worth remembering that don't belong 
+in core memory. Good for: learned preferences, important events, 
+reference material.
+
+recall: Comprehensive search across your conversation history AND archival 
+memory. Use this when you're trying to remember something but aren't sure 
+if it was in a conversation or saved to archival.
+```
+
+---
+
+## Context Building
+
+When building context for an LLM request:
+
+```rust
+pub struct ContextBuilder {
+    agent_id: AgentId,
+    memory_store: Arc<dyn MemoryStore>,
+}
+
+impl ContextBuilder {
+    pub async fn build_memory_section(&self) -> Result<String> {
+        let blocks = self.memory_store.list_agent_blocks(&self.agent_id).await?;
+        
+        let mut sections = Vec::new();
+        
+        for block in blocks {
+            // Skip archival blocks (retrieved on demand)
+            if block.block_type == MemoryBlockType::Archival {
+                continue;
+            }
+            
+            let content = block.document.get_text("content").to_string();
+            
+            // Format with label and description for the LLM
+            sections.push(format!(
+                "<{}>\n{}\n\n{}\n</{}>",
+                block.label,
+                block.description,
+                content,
+                block.label
+            ));
+        }
+        
+        Ok(sections.join("\n\n"))
+    }
+}
+```
+
+---
+
+## Migration from v1
+
+Memory blocks migrate via CAR export:
+
+```rust
+// v1 export includes:
+// - Raw content
+// - Label
+// - MemoryType (maps to block_type)
+// - Pinned status (maps to Core block_type)
+// - Permission (maps to read_only)
+
+// v2 import creates:
+// - New Loro document with content
+// - Sets agent_id based on import context
+// - Generates description from label if missing
+```
+
+---
+
+---
+
+## Constellation Resources
+
+Beyond agent-owned memory blocks, Pattern manages shared resources at the constellation level. This is a key differentiator from systems like Letta which focus on single-agent memory.
+
+### Resource Types
+
+```rust
+pub enum ConstellationResource {
+    /// Shared memory blocks (explicit sharing, has an owner)
+    SharedMemory {
+        block_id: MemoryBlockId,
+        owner: AgentId,
+        access_policy: AccessPolicy,
+    },
+    
+    /// Folders of files with automatic embedding
+    Folder {
+        id: FolderId,
+        name: String,
+        description: String,
+        embedding_config: EmbeddingConfig,
+    },
+    
+    /// Activity stream - system-maintained, read-only to agents
+    ActivityStream {
+        context_window: usize,    // recent events shown in context
+        retention: Duration,       // full history searchable
+    },
+    
+    /// Cross-agent shared context (summaries, notable events)
+    SharedContext {
+        summaries: Vec<ConversationSummary>,
+        summary_interval: Duration,
+        max_summaries: usize,
+    },
+    
+    /// Coordination state - explicit shared mutable state
+    Coordination {
+        state: CoordinationState,
+    },
+    
+    /// External data sources (bluesky, discord, etc.)
+    DataSource {
+        id: DataSourceId,
+        source_type: String,
+    },
+}
+```
+
+### Why Differentiate From Memory Blocks?
+
+v1 presented the activity log as a memory block, which confused agents - it *looked* like something they should edit but wasn't meant to be edited. The same problem applies to shared summaries, activity streams, etc.
+
+Clear differentiation:
+- **Memory blocks** - Agent-owned, agent-editable (with permissions)
+- **Constellation resources** - System-managed, agents consume/observe
+
+This reduces cognitive load on agents while giving them access to rich shared context.
+

+
+## Folders (File Access)
+
+Inspired by Letta's filesystem, but integrated with Pattern's multi-agent model.
+
+### Folder Structure
+
+```rust
+pub struct Folder {
+    pub id: FolderId,
+    pub name: String,
+    pub description: String,  // helps agents understand what's in it
+    pub path: FolderPath,     // local filesystem or virtual
+    pub embedding_config: EmbeddingConfig,
+    pub created_at: DateTime<Utc>,
+}
+
+pub enum FolderPath {
+    /// Local filesystem path
+    Local(PathBuf),
+    /// Virtual folder (files stored in DB)
+    Virtual,
+    /// Remote (future: S3, etc.)
+    Remote { url: String, credentials: String },
+}
+
+pub struct FolderFile {
+    pub id: FileId,
+    pub folder_id: FolderId,
+    pub name: String,
+    pub content_type: String,
+    pub size_bytes: u64,
+    pub uploaded_at: DateTime<Utc>,
+    pub indexed_at: Option<DateTime<Utc>>,
+}
+
+pub struct FilePassage {
+    pub id: PassageId,
+    pub file_id: FileId,
+    pub content: String,
+    pub start_line: usize,
+    pub end_line: usize,
+    pub embedding: Vec<f32>,
+}
+```
+
+### Folder Attachment
+
+When a folder is attached to an agent, they gain access to file tools:
+
+```rust
+pub struct FolderAttachment {
+    pub folder_id: FolderId,
+    pub agent_id: AgentId,
+    pub access: FolderAccess,
+    pub attached_at: DateTime<Utc>,
+}
+
+pub enum FolderAccess {
+    Read,       // can open, grep, search
+    ReadWrite,  // can also upload, modify
+}
+```
+
+Tools automatically available when folders are attached:
+- `/open <path>` - Open file, show window in context
+- `/read <path> [lines]` - Read specific lines
+- `/grep <pattern> [path]` - Regex search
+- `/search <folder> <query>` - Semantic search via embeddings
+
+Multiple agents can attach to the same folder with different access levels.
+
+### File Windowing
+
+Large files aren't dumped into context. Instead, a "window" is shown:
+
+```rust
+pub struct FileWindow {
+    pub file_id: FileId,
+    pub start_line: usize,
+    pub end_line: usize,
+    pub content: String,
+    pub has_more_before: bool,
+    pub has_more_after: bool,
+}
+```
+
+Agent can navigate: `/read file.rs lines 50-100` or `/read file.rs next` to scroll.
+
+### Future: Virtual Shell
+
+For more complex file operations, a sandboxed virtual shell could provide composable commands:
+
+```
+/sh ls project_docs/
+/sh grep -r "TODO" . | head -20
+/sh find . -name "*.rs" | wc -l
+```
+
+This is deferred for now but the folder/file infrastructure supports it.
+
+---
+
+## Activity Stream
+
+System-maintained log of constellation activity. Agents observe but don't manage.
+
+### Event Types
+
+```rust
+pub struct ActivityEvent {
+    pub id: ActivityEventId,
+    pub timestamp: DateTime<Utc>,
+    pub agent_id: Option<AgentId>,  // None = system event
+    pub event_type: ActivityEventType,
+    pub details: serde_json::Value,
+}
+
+pub enum ActivityEventType {
+    // Agent lifecycle
+    AgentActivated,
+    AgentDeactivated,
+    
+    // Communication
+    MessageReceived { source: String, summary: String },
+    MessageSent { target: String, summary: String },
+    
+    // Tool usage
+    ToolExecuted { tool: String, success: bool },
+    
+    // Memory changes
+    MemoryBlockUpdated { label: String, change_type: String },
+    
+    // File access
+    FileAccessed { folder: String, path: String, operation: String },
+    
+    // Coordination
+    TaskAssigned { task: String, assignee: AgentId },
+    HandoffInitiated { from: AgentId, to: AgentId },
+    
+    // Notable events (flagged by agents or system)
+    Notable { description: String, importance: Importance },
+}
+```
+
+### Context Inclusion
+
+Recent activity events are included in agent context:
+
+```
+<recent_activity>
+[2 hours ago] Flux responded to Bluesky thread about async Rust
+[4 hours ago] Entropy broke down task "refactor memory system" into 5 subtasks
+[yesterday] Partner updated persona block with new preferences
+[yesterday] Anchor flagged Flux's post for tone review
+</recent_activity>
+```
+
+Older events are searchable via `/search activity "keyword"`.
+
+---
+
+## Shared Context
+
+Cross-agent memory for constellation coherence, especially important for agents activated infrequently.
+
+### Structure
+
+```rust
+pub struct SharedContext {
+    /// Per-agent activity summaries
+    pub agent_summaries: HashMap<AgentId, AgentActivitySummary>,
+    
+    /// Constellation-wide periodic summaries
+    pub constellation_summaries: Vec<ConstellationSummary>,
+    
+    /// Key events worth long-term remembering
+    pub notable_events: Vec<NotableEvent>,
+}
+
+pub struct AgentActivitySummary {
+    pub agent_id: AgentId,
+    pub agent_name: String,
+    pub last_active: DateTime<Utc>,
+    pub recent_summary: String,  // LLM-generated
+    pub generated_at: DateTime<Utc>,
+    pub messages_covered: usize,
+}
+
+pub struct ConstellationSummary {
+    pub period_start: DateTime<Utc>,
+    pub period_end: DateTime<Utc>,
+    pub summary: String,
+    pub key_decisions: Vec<String>,
+    pub open_threads: Vec<String>,
+}
+
+pub struct NotableEvent {
+    pub timestamp: DateTime<Utc>,
+    pub event_type: String,
+    pub description: String,
+    pub agents_involved: Vec<AgentId>,
+    pub importance: Importance,
+}
+
+pub enum Importance {
+    Low,
+    Medium,
+    High,
+    Critical,
+}
+```
+
+### Context Building for Returning Agents
+
+When an agent is activated after a period of inactivity:
+
+```rust
+impl SharedContextManager {
+    pub async fn build_context_for_agent(
+        &self, 
+        agent_id: &AgentId,
+    ) -> Result<Option<String>> {
+        let last_active = self.db.get_agent_last_active(agent_id).await?;
+        let time_away = Utc::now() - last_active;
+        
+        // Recently active - minimal or no catch-up needed
+        if time_away < Duration::hours(1) {
+            return Ok(None);
+        }
+        
+        // Build catch-up context
+        let mut context = String::new();
+        
+        context.push_str(&format!(
+            "## Constellation Update (you were last active {})\n\n",
+            humanize_duration(time_away)
+        ));
+        
+        // What's happened since
+        let events_since = self.db
+            .get_activity_events_since(last_active)
+            .await?;
+        context.push_str(&self.format_events_summary(&events_since));
+        
+        // Key decisions
+        let decisions = self.db
+            .get_notable_events_since(last_active, Importance::Medium)
+            .await?;
+        if !decisions.is_empty() {
+            context.push_str("\n### Key Decisions\n");
+            for decision in decisions {
+                context.push_str(&format!("- {}\n", decision.description));
+            }
+        }
+        
+        // Per-agent summaries
+        context.push_str("\n### Agent Activity\n");
+        let summaries = self.db.get_all_agent_summaries().await?;
+        for summary in summaries {
+            if summary.agent_id != *agent_id {
+                context.push_str(&format!(
+                    "**{}** (last active: {})\n{}\n\n",
+                    summary.agent_name,
+                    humanize_time(summary.last_active),
+                    summary.recent_summary
+                ));
+            }
+        }
+        
+        Ok(Some(context))
+    }
+}
+```
+
+### Example Output
+
+For an agent waking up after a week:
+
+```
+## Constellation Update (you were last active 7 days ago)
+
+### What's Happened
+- 47 messages processed across the constellation
+- Flux handled 12 Bluesky threads
+- 3 tasks completed, 2 new tasks created
+- Partner had 2 direct conversations with Entropy
+
+### Key Decisions
+- Partner decided to pause project-X until next month
+- New policy: no engagement with political content on Bluesky
+- Memory system redesign approved, work started
+
+### Open Threads
+- Partner mentioned wanting to revisit medication adjustments
+- Ongoing discussion about v2 architecture
+
+### Agent Activity
+**Flux** (last active: 2 hours ago)
+Primarily handling Bluesky engagement. Responded to threads about Rust async 
+patterns and ADHD coping strategies. Tone was flagged once by Anchor.
+
+**Entropy** (last active: yesterday)
+Task breakdown focus. Created detailed subtasks for pattern v2 refactor. 
+Helped partner organize project priorities.
+
+**Anchor** (last active: 3 days ago)
+Reviewed 8 of Flux's public posts. Flagged 2 for tone adjustment, both resolved.
+No escalations to partner needed.
+```
+
+### Summary Generation
+
+Summaries are generated by LLM calls on a schedule:
+
+```rust
+pub struct SharedContextManager {
+    summarizer: Arc<dyn Summarizer>,
+    db: DatabaseConnection,
+}
+
+impl SharedContextManager {
+    /// Called periodically or on agent deactivation
+    pub async fn refresh_agent_summary(&self, agent_id: &AgentId) -> Result<()> {
+        let since = self.db.get_last_summary_time(agent_id).await?;
+        let messages = self.db
+            .get_agent_messages_since(agent_id, since)
+            .await?;
+        
+        if messages.len() < 5 {
+            return Ok(());  // not enough new activity
+        }
+        
+        let summary = self.summarizer.summarize(
+            &messages,
+            "Summarize this agent's recent activity in 2-3 sentences. \
+             Focus on what they worked on and any notable outcomes."
+        ).await?;
+        
+        self.db.update_agent_summary(agent_id, &summary).await
+    }
+    
+    /// Called on schedule (daily/weekly)
+    pub async fn generate_constellation_summary(&self) -> Result<()> {
+        let agent_summaries = self.db.get_all_agent_summaries().await?;
+        let notable = self.db.get_recent_notable_events(50).await?;
+        
+        let summary = self.summarizer.summarize_constellation(
+            &agent_summaries,
+            &notable,
+        ).await?;
+        
+        self.db.insert_constellation_summary(summary).await
+    }
+}
+```
+
+---
+
+## Coordination State
+
+Explicit shared mutable state for multi-agent coordination.
+
+```rust
+pub struct CoordinationState {
+    /// Task assignments
+    pub tasks: HashMap<TaskId, TaskAssignment>,
+    
+    /// Which agents are currently active
+    pub active_agents: HashSet<AgentId>,
+    
+    /// Handoff notes between agents
+    pub handoff_notes: HashMap<AgentId, HandoffNote>,
+    
+    /// Custom fields (constellation-configurable)
+    pub custom: serde_json::Value,
+}
+
+pub struct TaskAssignment {
+    pub task_id: TaskId,
+    pub description: String,
+    pub assigned_to: Option<AgentId>,
+    pub status: TaskStatus,
+    pub created_at: DateTime<Utc>,
+    pub updated_at: DateTime<Utc>,
+}
+
+pub struct HandoffNote {
+    pub from_agent: AgentId,
+    pub content: String,
+    pub created_at: DateTime<Utc>,
+}
+```
+
+Agents interact via dialect:
+
+```
+/coord status                        # view current state
+/coord assign "fix bug" to @entropy  # assign task  
+/coord complete task-123             # mark done
+/coord handoff @anchor "context..."  # leave notes for another agent
+/coord note "important observation"  # add to shared notes
+```

+
+## Open Questions
+
+1. **Embedding updates** - When block content changes, when do we regenerate embeddings?
+   - Option A: On every save (expensive)
+   - Option B: Background job (eventual consistency)
+   - Option C: On-demand when searching (lazy)
+
+2. **Loro snapshot frequency** - How often to consolidate updates into snapshots?
+   - Could be time-based (every N minutes)
+   - Or change-count based (every N updates)
+   - Or size-based (when updates exceed N bytes)
+
+3. **History retention** - How much Loro history to keep?
+   - Shallow snapshots after N days?
+   - Full history forever?
+   - Configurable per constellation?
+
+4. **Block templates** - Should templates be part of core, or an optional layer?
+
+5. **Diff visibility to agents** - Should agents see what changed between versions?
+   - Could add a "recent_changes" read-only block updated by system
+
+6. **Summary generation costs** - LLM calls for summaries add up. How to balance freshness vs cost?
+   - Generate on agent deactivation (natural breakpoint)
+   - Generate on schedule with batching
+   - Skip if activity below threshold
+
+7. **Shared context size** - How much catch-up context is too much?
+   - Configurable per agent role?
+   - Adaptive based on time away?

+# Pattern v2: Migration Path
+
+## Overview
+
+Migration from v1 to v2 uses the existing CAR (Content Addressable aRchive) export/import system. The compatibility layer lives at this boundary - v1 exports, v2 imports and transforms.
+
+## Existing CAR Export Structure
+
+v1 already has a solid export format:
+
+### Export Types
+- `Agent` - Single agent with messages and memories
+- `Group` - Agent group with member references
+- `Constellation` - Full constellation with all groups and agents
+
+### Data Structures
+
+```rust
+// Manifest (root of CAR file)
+ExportManifest {
+    version: u32,           // Currently 1
+    exported_at: DateTime,
+    export_type: ExportType,
+    stats: ExportStats,
+    data_cid: Cid,          // Points to actual export data
+}
+
+// Agent export
+AgentRecordExport {
+    id, name, agent_type,
+    model_id, model_config,
+    base_instructions,
+    // ... config fields ...
+    owner_id: UserId,       // v1 uses user ownership
+    message_chunks: Vec<Cid>,
+    memory_chunks: Vec<Cid>,
+}
+
+// Message chunk
+MessageChunk {
+    chunk_id: u32,
+    start_position: String,  // Snowflake ID
+    end_position: String,
+    messages: Vec<(Message, AgentMessageRelation)>,
+    next_chunk: Option<Cid>,
+}
+
+// Memory chunk
+MemoryChunk {
+    chunk_id: u32,
+    memories: Vec<(MemoryBlock, AgentMemoryRelation)>,
+    next_chunk: Option<Cid>,
+}
+```
+
+## Migration Strategy
+
+### Phase 1: Export from v1
+
+Use existing `pattern-cli export` commands:
+
+```bash
+# Export single agent
+pattern-cli export agent --name "MyAgent" -o agent.car
+
+# Export group
+pattern-cli export group --name "MyGroup" -o group.car
+
+# Export full constellation
+pattern-cli export constellation --name "MyConstellation" -o constellation.car
+```
+
+### Phase 2: Transform During Import
+
+The v2 importer reads v1 CAR files and transforms:
+
+```rust
+pub struct V2Importer {
+    db: ConstellationDb,
+}
+
+impl V2Importer {
+    pub async fn import_v1_car(&self, car_path: &Path) -> Result<ImportResult> {
+        // 1. Read CAR file
+        let car_reader = CarReader::new(File::open(car_path)?).await?;
+        
+        // 2. Parse manifest
+        let manifest = self.read_manifest(&car_reader).await?;
+        
+        // 3. Transform based on export type
+        match manifest.export_type {
+            ExportType::Agent => self.import_agent(&car_reader, &manifest).await,
+            ExportType::Group => self.import_group(&car_reader, &manifest).await,
+            ExportType::Constellation => self.import_constellation(&car_reader, &manifest).await,
+        }
+    }
+}
+```
+
+### Key Transformations
+
+#### 1. Memory Ownership Change
+
+v1: Memories owned by User, accessed by Agent via relation
+v2: Memories owned by Agent directly
+
+```rust
+fn transform_memory(
+    v1_memory: &V1MemoryBlock,
+    v1_relation: &AgentMemoryRelation,
+    target_agent_id: &AgentId,
+) -> V2MemoryBlock {
+    // Create Loro document with content
+    let doc = LoroDoc::new();
+    doc.get_text("content").insert(0, &v1_memory.value);
+    
+    V2MemoryBlock {
+        id: MemoryBlockId::generate(),
+        agent_id: target_agent_id.clone(),  // Now agent-owned
+        label: v1_memory.label.clone(),
+        description: generate_description(&v1_memory.label),  // Add description
+        block_type: map_memory_type(v1_memory.memory_type),
+        char_limit: 5000,  // Default
+        read_only: v1_relation.access_level < MemoryPermission::Append,
+        loro_snapshot: doc.export(ExportMode::Snapshot),
+        content_preview: truncate(&v1_memory.value, 200),
+        created_at: v1_memory.created_at,
+        updated_at: v1_memory.updated_at,
+    }
+}
+
+fn generate_description(label: &str) -> String {
+    match label {
+        "persona" => "Stores details about your current persona, guiding how you behave and respond.".into(),
+        "human" => "Stores key details about the person you are conversing with.".into(),
+        label if label.starts_with("archival_") => format!("Archival memory entry: {}", label),
+        _ => format!("Memory block: {}", label),
+    }
+}
+
+fn map_memory_type(v1_type: V1MemoryType) -> V2MemoryBlockType {
+    match v1_type {
+        V1MemoryType::Core => V2MemoryBlockType::Core,
+        V1MemoryType::Working => V2MemoryBlockType::Working,
+        V1MemoryType::Archival => V2MemoryBlockType::Archival,
+    }
+}
+```
+
+#### 2. Message Migration
+
+Messages stay largely the same, but move to SQLite:
+
+```rust
+fn transform_message(
+    v1_msg: &V1Message,
+    v1_relation: &AgentMessageRelation,
+    target_agent_id: &AgentId,
+) -> V2Message {
+    V2Message {
+        id: v1_msg.id.to_string(),
+        agent_id: target_agent_id.clone(),
+        position: v1_relation.position.to_string(),
+        batch_id: v1_relation.batch.map(|b| b.to_string()),
+        sequence_in_batch: v1_relation.sequence_num,
+        role: v1_msg.role.to_string(),
+        content: v1_msg.content.clone(),
+        tool_call_id: v1_msg.tool_call_id.clone(),
+        tool_name: v1_msg.tool_name.clone(),
+        tool_args: v1_msg.tool_args.clone(),
+        tool_result: v1_msg.tool_result.clone(),
+        source: None,  // Lost in v1 export
+        source_metadata: None,
+        is_archived: v1_relation.message_type == MessageRelationType::Archived,
+        created_at: v1_msg.created_at.to_rfc3339(),
+    }
+}
+```
+
+#### 3. Agent Configuration
+
+Agent config maps mostly 1:1, but stored differently:
+
+```rust
+fn transform_agent(v1_agent: &AgentRecordExport) -> V2Agent {
+    V2Agent {
+        id: v1_agent.id.to_string(),
+        name: v1_agent.name.clone(),
+        description: None,  // New field, not in v1
+        model_provider: extract_provider(&v1_agent.model_id),
+        model_name: extract_model(&v1_agent.model_id),
+        system_prompt: v1_agent.base_instructions.clone(),
+        config: json!({
+            "max_messages": v1_agent.max_messages,
+            "max_message_age_hours": v1_agent.max_message_age_hours,
+            "compression_threshold": v1_agent.compression_threshold,
+            "memory_char_limit": v1_agent.memory_char_limit,
+            "enable_thinking": v1_agent.enable_thinking,
+        }),
+        enabled_tools: vec!["context", "recall", "search", "send_message"],  // Defaults
+        tool_rules: transform_tool_rules(&v1_agent.tool_rules),
+        status: "active".into(),
+        created_at: v1_agent.created_at.to_rfc3339(),
+        updated_at: v1_agent.updated_at.to_rfc3339(),
+    }
+}
+```
+
+#### 4. Group/Constellation Structure
+
+Groups and constellations map cleanly:
+
+```rust
+fn transform_constellation(
+    v1_const: &V1Constellation,
+    v1_groups: &[V1GroupExport],
+) -> (V2Constellation, Vec<V2AgentGroup>) {
+    // Constellation becomes the database directory
+    let constellation = V2Constellation {
+        id: v1_const.id.to_string(),
+        owner_id: v1_const.owner_id.to_string(),
+        name: v1_const.name.clone(),
+        db_path: format!("constellations/{}", v1_const.id),
+        created_at: v1_const.created_at.to_rfc3339(),
+        last_accessed_at: Utc::now().to_rfc3339(),
+    };
+    
+    let groups = v1_groups.iter().map(|g| transform_group(g)).collect();
+    
+    (constellation, groups)
+}
+```
+
+### Phase 3: Verification
+
+After import, verify data integrity:
+
+```rust
+pub struct ImportVerifier {
+    db: ConstellationDb,
+}
+
+impl ImportVerifier {
+    pub async fn verify(&self, result: &ImportResult) -> Result<VerificationReport> {
+        let mut report = VerificationReport::default();
+        
+        // Check agent count matches
+        let agents = sqlx::query!("SELECT COUNT(*) as count FROM agents")
+            .fetch_one(self.db.pool())
+            .await?;
+        report.agents_imported = agents.count as usize;
+        report.agents_expected = result.expected_agents;
+        
+        // Check message count
+        let messages = sqlx::query!("SELECT COUNT(*) as count FROM messages")
+            .fetch_one(self.db.pool())
+            .await?;
+        report.messages_imported = messages.count as usize;
+        report.messages_expected = result.expected_messages;
+        
+        // Check memory blocks
+        let blocks = sqlx::query!("SELECT COUNT(*) as count FROM memory_blocks")
+            .fetch_one(self.db.pool())
+            .await?;
+        report.blocks_imported = blocks.count as usize;
+        report.blocks_expected = result.expected_blocks;
+        
+        // Sample content verification
+        report.sample_checks = self.verify_samples(result).await?;
+        
+        Ok(report)
+    }
+}
+```
+
+## CLI Commands
+
+```bash
+# v2 import command
+pattern-cli import --from v1.car --constellation "MyConstellation"
+
+# With verification
+pattern-cli import --from v1.car --constellation "MyConstellation" --verify
+
+# Dry run (parse and transform, don't write)
+pattern-cli import --from v1.car --dry-run
+
+# Import with explicit version
+pattern-cli import --from v1.car --version 1
+```
+
+## Export Version Bumping
+
+v2 exports will use version 2 format:
+
+```rust
+pub const EXPORT_VERSION: u32 = 2;
+
+// v2 export changes:
+// - Includes Loro snapshots instead of raw content
+// - Agent-scoped memories (no separate relation)
+// - SQLite-native types
+```
+
+v2 importer will handle both:
+
+```rust
+match manifest.version {
+    1 => self.import_v1(&car_reader).await,
+    2 => self.import_v2(&car_reader).await,
+    v => Err(CoreError::UnsupportedExportVersion(v)),
+}
+```
+
+## Rollback Strategy
+
+If v2 import fails or has issues:
+
+1. Original v1 CAR file is preserved (never modified)
+2. v2 constellation DB can be deleted and re-imported
+3. v1 system remains functional until migration verified
+
+```bash
+# Keep v1 running alongside v2 during transition
+pattern-cli-v1 chat --agent "MyAgent"  # Uses SurrealDB
+pattern-cli-v2 chat --agent "MyAgent"  # Uses SQLite
+
+# Once verified, decommission v1
+```
+
+## Interactive Migration
+
+v1 accumulated data quality issues that can't be automatically fixed:
+- Memory cross-contamination between agents
+- Attribution errors (wrong agent_id on memories)
+- Duplicate/conflicting blocks with same label
+- Orphaned data without valid agent references
+
+The migration tool provides an **interactive review mode** to resolve these.
+
+### Issue Detection
+
+During import, the migrator scans for problems:
+
+```rust
+pub struct MigrationIssue {
+    pub id: IssueId,
+    pub severity: IssueSeverity,
+    pub issue_type: IssueType,
+    pub description: String,

+
+pub enum SuggestedAction {
+    /// Keep as-is, assign to this agent
+    AssignTo(AgentId),
+    /// Delete this item
+    Delete,
+    /// Merge with another item
+    MergeWith(String),
+    /// Split into multiple items
+    Split(Vec<String>),
+    /// Keep both versions
+    KeepBoth,
+    /// Manual edit required
+    ManualEdit,
+    /// Skip/ignore
+    Skip,
+}
+```

+### Non-Interactive Mode
+
+For scripted migrations, issues can be exported and resolved via config:
+
+```bash
+# Export issues to JSON
+pattern-cli import --from constellation.car --analyze-only > issues.json
+
+# Edit issues.json to add resolutions...
+
+# Import with resolutions
+pattern-cli import --from constellation.car --resolutions issues.json

+After import, additional tools help clean up:
+
+```bash
+# Find remaining anomalies
+pattern-cli db analyze --constellation "MyConstellation"
+
+# Bulk reassign memories
+pattern-cli db reassign-memories --from-agent flux --to-agent entropy --label "task_*"
+
+# Merge duplicate blocks
+pattern-cli db merge-blocks --keep block_id_1 --merge block_id_2
+
+# Delete orphaned data
+pattern-cli db cleanup --remove-orphans --dry-run
+pattern-cli db cleanup --remove-orphans
+
+# Regenerate embeddings for specific blocks
+pattern-cli db reindex --agent flux --type archival
+```
+
+---
+
+## Known Limitations
+
+1. **Embeddings** - May need regeneration if model changed
+2. **Live queries** - v1 subscriptions don't migrate (not persisted)
+3. **Timestamps** - Some precision may be lost in conversion
+4. **Custom metadata** - Unrecognized fields in v1 config will be dropped
+5. **Semantic analysis limits** - Heuristics can't catch all attribution errors; user review is essential
+
+## Migration Checklist
+
+- [ ] Export all constellations from v1
+- [ ] Backup v1 SurrealDB (just in case)
+- [ ] Install v2 pattern-cli
+- [ ] Run analysis on each export: `pattern-cli import --analyze-only`
+- [ ] Review and resolve issues interactively or via resolution file
+- [ ] Import each constellation with `--interactive` or `--resolutions`
+- [ ] Verify import counts match
+- [ ] Run `pattern-cli db analyze` on imported constellation
+- [ ] Test agent interactions
+- [ ] Regenerate embeddings if needed: `pattern-cli db reindex`
+- [ ] Update any external integrations (Discord bot config, etc.)
+- [ ] Keep v1 running in parallel during verification period
+- [ ] Decommission v1 after verification complete

+# Pattern v2: Architecture Rework
+
+## Background
+
+Pattern v1 was written in "a fit of madness" - rapid prototyping that taught us what the actual requirements are. This document captures the vision for v2, which takes those lessons and rebuilds the core data layer properly.
+
+## Problems with v1
+
+### Database (SurrealDB)
+
+1. **Global memory live query** - `subscribe_to_agent_memory_updates` ignores agent_id entirely, watching ALL memory blocks. Any memory update from any agent triggers updates to all agents.
+
+2. **No row-level security** - All isolation is application-level query filtering. One bad query = data bleed between agents.
+
+3. **Memory ownership confusion** - Memories belong to User, not Agent. Multiple agents can share memory blocks if labels collide.
+
+4. **Edge direction inconsistencies** - `group_members` is backwards from all other edge patterns.
+
+5. **Accumulated gotchas** - Datetime serialization issues, ID bracket parsing, LIVE SELECT parameter limitations, etc.
+
+6. **Custom entity macro nightmare** - `#[derive(Entity)]` was built to work around SurrealDB pain points but became its own source of complexity.
+
+### Memory System (DashMap-based)
+
+1. **In-memory caching creates sync problems** - DashMap holds memory state, DB holds another copy, they can desync.
+
+2. **Namespace collisions** - Same label across agents in constellation = last write wins.
+
+3. **No history/versioning** - Memory updates are destructive, no way to see what changed or roll back.
+
+4. **Agents must manually maintain logs** - No system-level rolling logs.
+
+5. **No templated/structured memories** - Everything is opaque strings.
+
+## v2 Goals
+
+### Database Layer
+
+- **SQLite + sqlx** - Boring, reliable, well-understood
+- **One database per constellation** - Physical isolation, cross-contamination impossible at storage level
+- **Vector search via sqlite-vec** - Extension-based, proven approach
+- **No custom entity macro** - Just sqlx queries, maybe light derive helpers
+- **Simple relational model** - Foreign keys and junction tables, no graph magic
+
+### Memory Layer
+
+- **Loro CRDT-backed documents** - Every edit tracked, mergeable, time-travel capable
+- **No in-memory caching** - DB is single source of truth, read when needed, write immediately
+- **Versioned memories** - Agents can see edit history, roll back bad updates
+- **Templated memories** - Structured schemas for common patterns
+- **Rolling logs** - System-maintained, agents observe but don't manage
+- **Diffing/rollback exposed to users** - Maybe to agents too
+
+### Agent Runtime
+
+- **Pattern owns LLM calls** - Not an MCP tool bolted onto something else
+- **Context building stays internal** - Deep integration into the context maintenance process
+- **Coding harness** - Pattern can be a coding agent runtime
+- **ACP support** - Agent Client Protocol for editor integration (Zed, JetBrains, Neovim, etc.)
+  - Pattern implements the `Agent` trait from `agent-client-protocol` crate
+  - Runs as subprocess, communicates via JSON-RPC over stdio
+  - Editors can spawn Pattern agents and interact through standard protocol
+  - See v2-api-surface.md for details
+
+### Interface Architecture
+
+v1 had the CLI as the primary interface - it directly instantiated agents, hit the DB, made LLM calls. The server was a stub for future multi-user hosting.
+
+v2 rethinks this:
+
+- **CLI remains important** - Trusted local interaction point. Agent knows CLI input is from their partner human, unlike Discord/Bluesky input from strangers.
+- **Server as coordination layer** - HTTP API for external integrations, multi-user hosting, but not the only way to run agents
+- **Remote presence connectors** - For coding harness and ACP, agents on a server need to reach into the partner's local environment:
+  - Read/write files on partner's machine
+  - Connect to local editor instances (LSP integration)
+  - CLI could work over such a connector too
+  - Enables "agent runs on server, acts on local dev environment" model
+
+The trust model matters: CLI = partner (trusted), Discord/Bluesky = conversant (verify), Remote connector = partner's environment (trusted proxy).
+
+## Non-Goals
+
+- Backwards compatibility at the API level (CAR export/import is the migration path)
+- Supporting SurrealDB alongside SQLite
+- Preserving the entity macro system
+
+## Migration Path
+
+Existing constellations migrate via:
+1. CAR file export from v1
+2. CAR file import to v2
+
+The compatibility layer lives at the export/import boundary, not in the runtime.
+
+## Key Design Decisions
+
+### One DB Per Constellation
+
+Benefits:
+- Physical isolation - no query can accidentally leak across constellations
+- SQLite's single-writer limitation becomes a non-issue (one constellation = one writer)
+- Easy backup/restore per constellation
+- Natural sharding if we ever need horizontal scale
+
+Trade-offs:
+- Cross-constellation queries require opening multiple DBs
+- Slightly more complex connection management
+
+### Loro for Memory Documents
+
+Benefits:
+- Built-in versioning and history
+- CRDT means eventual consistency if we ever need it
+- Rich document primitives (text, lists, maps, trees)
+- Diff visibility built-in
+
+Trade-offs:
+- Another dependency
+- Learning curve for the Loro model
+- Need to understand how it persists/snapshots
+
+### No In-Memory Cache
+
+Benefits:
+- Single source of truth
+- No sync bugs possible
+- Simpler mental model
+
+Trade-offs:
+- More DB reads
+- Need to think about query efficiency
+
+## Open Questions
+
+1. ~~How does Loro persistence work?~~ **Answered**: Snapshots + delta updates, both as byte blobs. We store snapshots in SQLite, updates in a separate table, consolidate periodically.
+2. ~~What memory primitives does Letta use?~~ **Answered**: Labeled blocks with descriptions, read-only option, shared blocks between agents. See v2-memory-system.md.
+3. How do we handle the constellation-level shared state (activity tracker, etc.)?
+4. What's the right API surface for the HTTP server?
+5. Should agents have write access to their own version history, or is that user-only?
+6. Remote presence connector protocol - what does the interface look like?
+7. Trust levels for different input sources - how does this affect tool access?

+
+### Models
+
+All models use `sqlx::FromRow` with proper type mappings:
+
+| Model | Key Features |
+|-------|--------------|
+| `Agent` | JSON fields for config, tools, rules; `ModelRoutingConfig` for dynamic model selection |
+| `AgentGroup` | Coordination patterns stored as JSON |
+| `MemoryBlock` | Loro snapshots as `Vec<u8>` blobs, permissions system |
+| `Message` | Snowflake ID ordering, batch tracking, tool call/response pairing |
+| `ArchiveSummary` | Summary chaining via `previous_summary_id` and `depth` for recursive compression |
+| `ActivityEvent` | Importance levels as sqlx enum |
+| `ConstellationSummary` | JSON arrays for key_decisions, open_threads |
+| `DataSource` | Comprehensive `SourceType` enum (VCS, LSP, GroupChat, Email, MCP, etc.) |
+| `Task` | ADHD-aware task management with status, priority, hierarchy, time estimates |
+| `Event` | Calendar events with iCal RRULE recurrence, reminders |
+| `Folder` + `FilePassage` | File access with chunked passages for semantic search |
+| `MigrationAudit` | v1→v2 migration tracking with detailed logs |
+
+#### Model Routing
+
+`ModelRoutingConfig` enables dynamic model selection:
+- Fallback models for rate limits or context overflow
+- Rules based on: cost threshold, context length, tool calls, time windows, source type
+- Per-rule temperature/max_tokens overrides
+
+### Queries
+
+Most queries use compile-time checked macros (`sqlx::query!`, `sqlx::query_as!`):
+
+- **agent.rs**: Full CRUD, group management, status updates
+- **memory.rs**: Block CRUD, shared blocks, delta storage, checkpoints, consolidation
+- **message.rs**: Message insert/query, batch operations, archival
+- **coordination.rs**: Activity events, summaries, tasks, handoffs
+- **event.rs**: Full CRUD for events, occurrences, upcoming events queries
+- **task.rs**: Full CRUD with hierarchy, due date filtering, status queries
+- **folder.rs**: Full CRUD for folders, files, passages, attachments
+- **source.rs**: Full CRUD for data sources, agent subscriptions
+
+### Vector Search (sqlite-vec)
+
+**Fully implemented** via `src/vector.rs`:
+
+- **Global extension registration** via `libsqlite3-sys::sqlite3_auto_extension`
+- **vec0 virtual table** for embeddings with auxiliary columns
+- **KNN search** with optional content type filtering (post-query filter)
+- **CRUD operations**: insert, delete, update embeddings
+- **Stats**: embedding counts by content type
+- **Zerocopy** for efficient `Vec<f32>` to bytes conversion
+
+Key functions:
+- `init_sqlite_vec()` - Register extension globally (called automatically on DB open)
+- `ensure_embeddings_table(pool, dimensions)` - Create vec0 virtual table
+- `insert_embedding()`, `delete_embeddings()`, `update_embedding()`
+- `knn_search()`, `search_similar()` - Vector similarity search
+- `verify_sqlite_vec()` - Health check returning version string
+
+**Note**: Vector queries use runtime `sqlx::query_as()` instead of compile-time macros because:
+1. vec0 KNN syntax (`WHERE embedding MATCH ? AND k = ?`) isn't standard SQL
+2. Table created at runtime, not in migrations
+3. Dynamic dimensions per constellation
+
+### Full-Text Search (FTS5)
+
+**Fully implemented** via `src/fts.rs`:
+
+- **Built into SQLite** - No extension loading required (unlike sqlite-vec)
+- **External content tables** - FTS indexes existing tables without duplicating data
+- **Automatic sync** - Triggers keep FTS indexes updated on INSERT/UPDATE/DELETE
+- **BM25 ranking** - Results sorted by relevance using FTS5's built-in ranking
+
+Tables indexed:
+- `messages_fts` - Indexes `messages.content`
+- `memory_blocks_fts` - Indexes `memory_blocks.content_preview`
+- `archival_fts` - Indexes `archival_entries.content`
+
+Key functions:
+- `search_messages()` - Search message content with optional agent filter
+- `search_memory_blocks()` - Search memory block previews
+- `search_archival()` - Search archival entries
+- `search_all()` - Search across all content types, merged by rank
+- `rebuild_*_fts()` - Rebuild indexes after bulk imports
+- `get_fts_stats()` - Get index statistics
+- `validate_fts_query()` - Basic query syntax validation
+
+FTS5 query syntax supported:
+- Basic: `word1 word2` (AND)
+- Phrase: `"exact phrase"`
+- OR: `word1 OR word2`
+- NOT: `word1 NOT word2`
+- Prefix: `prefix*`
+
+**Note**: FTS queries use runtime `sqlx::query_as()` because they join FTS virtual tables
+with source tables and use bm25() ranking, which is easier to express at runtime.
+
+### Hybrid Search
+
+**Fully implemented** via `src/search.rs`:
+
+Combines FTS5 keyword search with vector similarity search for best-of-both-worlds retrieval.
+
+Search modes:
+- `FtsOnly` - Fast keyword search, good for exact matches
+- `VectorOnly` - Semantic search, good for conceptual similarity  
+- `Hybrid` - Combines both (default), best for most use cases
+
+Fusion methods:
+- **RRF (Reciprocal Rank Fusion)** - Default, combines based on rank positions, parameter-free
+- **Linear combination** - Weighted average of normalized scores, tunable weights
+
+Key types:
+- `HybridSearchBuilder` - Fluent builder for constructing searches
+- `SearchResult` - Unified result with combined score and breakdown
+- `ContentFilter` - Filter by content type and/or agent
+- `ScoreBreakdown` - Individual FTS/vector scores for debugging
+
+Example usage:
+```rust
+use pattern_db::search::{search, ContentFilter, SearchMode};
+
+// Hybrid search (text + embedding)
+let results = search(pool)
+    .text("ADHD task management")
+    .embedding(query_embedding)
+    .filter(ContentFilter::messages(Some("agent_1")))
+    .limit(10)
+    .execute()
+    .await?;
+
+// FTS-only search
+let results = search(pool)
+    .text("deadline reminder")
+    .mode(SearchMode::FtsOnly)
+    .execute()
+    .await?;
+
+// Vector-only search  
+let results = search(pool)
+    .embedding(query_embedding)
+    .mode(SearchMode::VectorOnly)
+    .max_vector_distance(0.5)
+    .execute()
+    .await?;
+```
+
+### Schema
+
+The migration creates all tables from v2-database-design.md:
+
+- Core: `agents`, `agent_groups`, `group_members`
+- Memory: `memory_blocks`, `memory_block_updates`, `memory_block_checkpoints`, `shared_block_agents`, `archival_entries`
+- Messages: `messages`, `archive_summaries`
+- Coordination: `activity_events`, `agent_summaries`, `constellation_summaries`, `notable_events`, `coordination_state`, `coordination_tasks`, `handoff_notes`
+- Vectors: `embeddings` (vec0 virtual table, created at runtime)
+- FTS5: `messages_fts`, `memory_blocks_fts`, `archival_fts` (external content tables with sync triggers)
+
+### Build System
+
+- **Offline mode**: `.sqlx/` contains cached query metadata for CI builds
+- **Dev database**: `dev.db` in crate root for compile-time checking
+- **Editor integration**: Set `SQLX_OFFLINE=true` in environment to silence LSP false positives
+
+## Technical Decisions
+
+### sqlite-vec Integration
+
+Uses `libsqlite3-sys` directly to call `sqlite3_auto_extension()`:
+
+```rust
+// In vector.rs - the ONE place with unsafe code
+pub fn init_sqlite_vec() {
+    INIT.call_once(|| {
+        unsafe {
+            let init_fn = sqlite_vec::sqlite3_vec_init as *const ();
+            let init_fn: unsafe extern "C" fn(...) = std::mem::transmute(init_fn);
+            libsqlite3_sys::sqlite3_auto_extension(Some(init_fn));
+        }
+    });
+}
+```
+
+**Dependencies**:
+- `sqlite-vec = "0.1.7-alpha.2"` - Bundles C source, compiles via `cc`
+- `libsqlite3-sys = "=0.30.1"` - Pinned to match sqlx (semver-exempt linkage)
+- `zerocopy = "0.8"` - Zero-copy `Vec<f32>` to bytes
+
+### JSON Fields
+
+Using `sqlx::types::Json<T>` wrapper instead of `#[sqlx(json)]` attribute:
+
+```rust
+pub struct Agent {
+    pub config: Json<AgentConfig>,
+    pub enabled_tools: Json<Vec<String>>,
+    pub tool_rules: Option<Json<ToolRules>>,
+}
+```
+
+### SQLite Integer Types
+
+All integer columns use `i64` (SQLite INTEGER is always 64-bit internally).
+
+### Column Type Annotations
+
+For compile-time macros with nullable or custom-typed columns:
+
+```rust
+sqlx::query_as!(
+    Agent,
+    r#"SELECT 
+        id as "id!",
+        status as "status!: AgentStatus",
+        config as "config!: _"
+    FROM agents WHERE id = ?"#,
+    id
+)
+```
+
+### Connection Management
+
+`ConstellationDb` wraps a `SqlitePool` with:
+- sqlite-vec registered globally before first connection
+- WAL mode for concurrent reads
+- 5 max connections (SQLite is single-writer)
+- Automatic migration on open
+- Pragmas for performance (cache_size, mmap_size, etc.)
+
+## What's Missing
+
+### High Priority
+
+1. **Integration with pattern_core** - Replace SurrealDB calls with pattern_db
+2. **More tests** - Query function unit tests, integration tests
+
+### Medium Priority
+
+1. **Global database** - User accounts, constellation registry (server mode)
+2. **Migration tooling** - CAR import to new schema
+
+### Lower Priority
+
+1. **Backup/vacuum commands** - CLI integration
+
+## Usage
+
+### Development
+
+```bash
+# Create/update dev database
+cd crates/pattern_db
+sqlx database create
+sqlx migrate run
+
+# Regenerate offline data after query changes
+DATABASE_URL="sqlite:crates/pattern_db/dev.db" cargo sqlx prepare --workspace
+
+# Build (uses offline data)
+SQLX_OFFLINE=true cargo check -p pattern_db
+```
+
+### In Code
+
+```rust
+use pattern_db::{ConstellationDb, queries, vector, models::*};
+
+// Open database (creates if missing, runs migrations, registers sqlite-vec)
+let db = ConstellationDb::open("path/to/constellation.db").await?;
+
+// Verify sqlite-vec is loaded
+let version = vector::verify_sqlite_vec(db.pool()).await?;
+println!("sqlite-vec {}", version);
+
+// Create embeddings table (384 dimensions for bge-small)
+vector::ensure_embeddings_table(db.pool(), 384).await?;
+
+// Insert an embedding
+vector::insert_embedding(
+    db.pool(),
+    vector::ContentType::Message,
+    "msg_123",
+    &embedding_vec,  // Vec<f32>
+    None,            // chunk_index
+    Some("hash123"), // content_hash for staleness detection
+).await?;
+
+// KNN search
+let results = vector::knn_search(
+    db.pool(),
+    &query_embedding,
+    10,  // k
+    Some(vector::ContentType::Message),  // optional filter
+).await?;
+
+for result in results {
+    println!("{}: distance={}", result.content_id, result.distance);

+# Pattern Dialect - Action Language for Agents
+
+## Overview
+
+Pattern Dialect is a lightweight action language designed to replace structured tool calls (JSON/XML) with something that:
+
+1. **LLMs can produce reliably** - even smaller/cheaper models
+2. **Is easy to parse** - sigil-based structure with fuzzy argument matching
+3. **Meets models where they are** - dense aliases for common operations
+4. **Integrates with Pattern's permission system** - explicit markers for consent flows
+
+The core insight: LLMs already have "intuitions" about how to express actions. Rather than forcing them into rigid schemas, we provide a flexible surface that maps many expressions to the same underlying operations.
+
+## Design Principles
+
+### Hard to Fail, Hard to Be Dangerous
+
+- **Fuzzy matching** on verbs and arguments
+- **Context inference** when targets are ambiguous
+- **Sensible defaults** for omitted parameters
+- **Permission gates invisible in syntax** - the system always checks, agents don't need to specify
+
+### Meet Models Where They Are
+
+- Dense alias tables for common operations
+- Multiple syntactic forms for the same action
+- Accept natural language fragments when unambiguous
+- Intent inference from argument shape (e.g., `/recall "query text"` vs `/recall block_name`)
+
+### Explicit Permission Requests
+
+When an agent *knows* something might need approval:
+
+| Marker | Meaning |
+|--------|---------|
+| (none) | Normal - system checks silently |
+| `.` | "This is routine, don't bug them" |
+| `?` | "This might need checking" |
+| `?ask` | "Please confirm with partner" |
+| `!` | "This is serious, definitely confirm" |
+
+## Syntax
+
+### Basic Structure
+
+```
+/VERB [ARGUMENTS] [PERMISSION_MARKER]
+```
+
+- `/` sigil marks an action (familiar from Discord/Slack/IRC)
+- `VERB` is fuzzy-matched against known verbs + aliases
+- `ARGUMENTS` are parsed based on verb signature
+- Optional permission marker at end
+
+### Chaining
+
+```
+/action1 -> /action2 -> /action3
+```
+
+`->` means "then prompt me again with the result". Not a pipe - the agent gets control back between each action.
+
+### References
+
+```
+@last              # last message in context
+@last.message      # same, more explicit  
+@last.output       # output of last action
+@thread            # current thread/conversation
+@parent            # message being replied to
+@[uri]             # specific resource by URI
+
+that, this, it     # implicit references resolved from context
+```
+
+### Content Blocks
+
+Any of these are recognized as "this is the content":
+
+```
+/post bluesky "single line content"
+/post bluesky """
+multi-line
+content
+"""
+/post bluesky ```
+code block style
+```
+/post bluesky
+> block quote
+> also works
+```
+
+Unquoted content is fine when unambiguous:
+
+```
+/reply sounds good to me
+/recall user mentioned project deadlines
+```
+
+## Verb Reference
+
+### Memory Operations
+
+#### `/recall` - Long-term Memory
+
+The most aliased verb. Intent is inferred from argument shape.
+
+| Form | Interpretation |
+|------|----------------|
+| `/recall block_name` | Read block by exact name |
+| `/recall "fuzzy query"` | Vector search |
+| `/recall + "content"` | Insert new block |
+| `/recall block_name + "content"` | Append to existing |
+| `/recall -block_name` | Delete block |
+| `/recall patch block_name \`\`\`diff...` | Structured edit |
+
+**Aliases**: `remember`, `store`, `save`, `archive`, `forget` (→ delete)
+
+**Subcommand forms** (equivalent to modifiers):
+- `insert`, `add`, `save` → Insert
+- `append`, `+` → Append  
+- `read`, `get`, `check`, `show` → Read
+- `delete`, `remove`, `-` → Delete
+- `patch`, `edit` → Patch (for capable models)
+
+#### `/context` - Working Memory
+
+Operations on memory blocks that are always in context (persona, human, working notes).
+
+| Form | Interpretation |
+|------|----------------|
+| `/context block_name + "content"` | Append to block |
+| `/context block_name "old" -> "new"` | Replace text |
+| `/context archive block_name` | Move to archival |
+| `/context load archival_label` | Load from archival |
+| `/context swap block archival_label` | Swap working ↔ archival |
+
+**Aliases**: `note`, `update`, `remember` (context-aware disambiguation)
+
+#### `/search` - Query Across Domains
+
+| Form | Interpretation |
+|------|----------------|
+| `/search query terms` | Search all, return grouped |
+| `/search in archival query` | Archival memory only |
+| `/search in conversations query` | Conversation history |
+| `/search in constellation query` | All agents' history |
+| `/search query > 2 weeks` | Time-filtered |
+| `/search query role:assistant` | Role-filtered |
+
+**Aliases**: `find`, `query`, `look`, `lookup`
+
+**Domain modifiers**: `in archival`, `in conversations`, `in constellation`, `in all`, `everywhere`
+
+### Communication
+
+#### `/send` - Explicit Target Form
+
+```
+/send @domain @target "message"
+```
+
+Domains: `@user`, `@agent`, `@channel`, `@bluesky`, `@discord`
+
+Examples:
+```
+/send @agent @entropy "can you help break this down?"
+/send @bluesky @at://did:plc:xxx/post/yyy "replying here"
+/send @discord @general "hey everyone"
+/send @user "here's what I found"
+```
+
+#### Shorthands
+
+| Verb | Target | Use |
+|------|--------|-----|
+| `/reply` | Current thread | Reply to the message being responded to |
+| `/post` | Platform | Post to Bluesky, Discord, etc. |
+| `/dm` | User | Direct message |
+| `/tell` | Agent | Agent-to-agent communication |
+
+Examples:
+```
+/reply sounds good .                     # routine reply
+/post bluesky "thoughts on this" ?public # flag as public
+/dm @user "private info" ?               # might need checking
+/tell @anchor "should I do this?" ?ask   # request approval
+```
+
+### External Operations
+
+#### `/fetch` - Get Web Content
+
+```
+/fetch https://example.com           # as markdown
+/fetch https://example.com html      # as raw html
+/fetch continue                      # continue paginated read
+```
+
+**Aliases**: `get` (url context)
+
+#### `/web` - Web Search
+
+```
+/web rust async patterns
+/web site:docs.rs tokio runtime
+```
+
+**Aliases**: `search web`, `google`, `look up`
+
+### Utilities
+
+#### `/calc` - Calculation
+
+```
+/calc 5 feet to meters
+/calc radius = 5; pi * radius^2
+/calc 20% of 350
+```
+
+**Aliases**: `calculate`, `compute`, `math`
+
+#### `/data` - Data Sources
+
+```
+/data list                           # show configured sources
+/data read source_id                 # read from source
+/data search source_id "query"       # search in source
+/data monitor source_id              # start notifications
+/data pause source_id                # pause notifications
+```
+
+### Authority Operations
+
+Only available to agents with authority roles.
+
+#### `/approve` - Grant Permission
+
+```
+/approve [request-id]
+/approve [request-id] always         # create permanent rule
+```
+
+**Aliases**: `allow`, `permit`, `ok`, `yes`
+
+#### `/deny` - Deny Permission
+
+```
+/deny [request-id]
+/deny [request-id] "reason"
+/deny [request-id] always            # create permanent block
+```
+
+**Aliases**: `reject`, `block`, `no`
+
+#### `/escalate` - Punt to Higher Authority
+
+```
+/escalate [request-id]
+/escalate [request-id] "this needs human review"
+```
+
+#### `/cancel` - Cancel Pending Action
+
+```
+/cancel                              # cancel current chain

+```
+
+**Aliases**: `abort`, `nevermind`, `stop`
+
+### Emergency
+
+#### `/halt` - Emergency Stop
+
+```
+/halt "reason for emergency stop" !
+```
+
+Only for system integrity agents. Terminates the process.
+
+## Parser Architecture
+
+### Intent Resolution Flow
+
+```
+1. Find sigil (/)
+2. Extract verb token
+3. Fuzzy match verb → canonical + aliases
+4. Based on verb, parse arguments using signature
+5. Extract permission markers
+6. Resolve references (@last, that, etc.)
+7. Infer intent from argument shape if needed
+8. Return structured action
+```
+
+### Fuzzy Matching
+
+```rust
+fn match_verb(input: &str) -> Option<(Verb, f32)> {
+    // 1. Exact match against canonical
+    // 2. Exact match against aliases
+    // 3. Levenshtein distance (weighted by verb strictness)
+    // 4. Return best match above threshold
+}
+```
+
+Each verb has a `strictness` level:
+- **Strict**: `approve`, `deny`, `halt` - don't want accidental matches
+- **Normal**: most verbs
+- **Loose**: `recall`, `search` - maximize accessibility
+
+### Argument Shape Inference
+
+For `/recall`:
+```rust
+fn interpret_recall(args: &str) -> RecallIntent {
+    if has_insert_modifier(args) {
+        RecallIntent::Insert(extract_content(args))
+    } else if has_delete_modifier(args) {
+        RecallIntent::Delete(extract_label(args))
+    } else if has_patch_modifier(args) {
+        RecallIntent::Patch(extract_patch(args))
+    } else if is_exact_block_match(args) {
+        RecallIntent::Read(args.to_string())
+    } else {
+        // No exact match - treat as semantic search
+        RecallIntent::Search(args.to_string())
+    }
+}
+```
+
+### Error Recovery
+
+When parsing fails or is ambiguous, return natural language:
+
+```
+"I couldn't tell if you meant /post or /reply - which one?"
+"'recall' found multiple blocks matching 'notes' - did you mean project_notes or meeting_notes?"
+"No permission to post to bluesky DMs - want me to ask?"
+```
+
+## Permission Integration
+
+### Implicit Checks (Always Run)
+
+- Platform access
+- Rate limits  
+- Content policies
+- DM vs public context
+- Sensitivity heuristics
+
+### Authority Resolution
+
+```rust
+enum Authority {
+    Partner,                          // Human owner
+    Agent(AgentId),                   // Supervisor agent
+    Chain(Vec<Authority>),            // Try in order, escalate
+}
+```
+
+Configured per action pattern:
+- `/post bluesky` public → `Chain([Agent(anchor), Partner])`
+- `/recall` sensitive → `Partner`
+- `/send dm` → `Partner`
+
+### Tiered Model Support
+
+Routine permission checks can run on smaller/cheaper models:
+- Local model handles 95% of traffic instantly
+- Larger model handles edge cases
+- Partner only sees truly novel situations
+
+The small model can signal uncertainty:
+```
+/uncertain "this looks like sarcasm but I can't tell"
+/escalate "content seems political, above my pay grade"
+```
+
+## Agent Instructions
+
+The model-facing documentation is minimal:
+
+```
+Actions start with /
+
+Common verbs:
+  /recall - memory (read, search, store)
+  /search - find things
+  /reply - respond to messages
+  /post - publish to platforms
+  /tell - message other agents
+
+Chain actions with ->
+End with ? to request permission, ! if serious, . if routine
+
+Examples:
+  /recall project deadlines
+  /reply sounds good .
+  /post bluesky "hello" ?public
+  /recall meeting notes -> /summarize -> /tell @entropy
+```
+
+## Implementation Notes
+
+### Crate Location
+
+`pattern_core::dialect` or separate `pattern_dialect` crate.
+
+### Key Types
+
+```rust
+pub struct ParsedAction {
+    pub verb: Verb,
+    pub arguments: Arguments,
+    pub permission_marker: Option<PermissionMarker>,
+    pub chain: Option<Box<ParsedAction>>,
+}
+
+pub enum Arguments {
+    Recall(RecallIntent),
+    Send(SendTarget, Content),
+    Search(SearchQuery),
+    // ...
+}
+
+pub struct DialectParser {
+    verb_specs: HashMap<String, VerbSpec>,
+    block_registry: BlockRegistry,  // for exact match detection
+}
+```
+
+### Integration with Existing Tools
+
+The dialect parser produces structured actions that map directly to existing tool invocations. The `BuiltinTools` implementations remain unchanged - dialect is a new frontend, not a replacement of the execution layer.
+
+```
+Agent Output → Dialect Parser → ParsedAction → Tool Execution → Result
+```
+
+## Future Considerations
+
+### Learning from Usage
+
+Track which phrasings agents attempt:
+- Add successful novel phrasings as aliases
+- Identify common failure patterns
+- Per-model alias tuning
+
+### Visual/TUI Representation
+
+The dialect is text-first but could render nicely:
+- Syntax highlighting in logs
+- Structured display in partner UI
+- Action history with grouping
+
+### Multi-Action Batching
+
+Beyond chaining, explicit parallel execution:
+```
+/batch {
+  /recall project_notes
+  /search conversations about project
+  /fetch https://project-docs.example.com
+}
+```

+# Pattern v2: Remote Presence Connector
+
+## The Problem
+
+Pattern agents often run on a server (for reliability, always-on presence), but need to interact with the partner's local environment:
+
+- Read/write files on partner's machine
+- Connect to local editor (LSP integration)
+- Execute commands in partner's terminal
+- Access local development tools
+
+This is especially important for:
+1. **Coding harness** - Agent needs to see code, run tests, use dev tools
+2. **ACP (Agent Communication Protocol)** - Agents coordinating across environments
+3. **ADHD support** - Agent helping with tasks that involve local files/apps
+
+## Current State
+
+`realtime.rs` has event sink traits for streaming agent responses:
+
+```rust
+#[async_trait]
+pub trait AgentEventSink: Send + Sync {
+    async fn on_event(&self, event: ResponseEvent, ctx: AgentEventContext);
+}
+```
+
+This is one-way (agent → observer). We need bidirectional communication.
+
+## Proposed Architecture
+
+### Connector Trait
+
+```rust
+/// A connector provides access to an environment (local or remote)
+#[async_trait]
+pub trait EnvironmentConnector: Send + Sync {
+    /// Read a file from the environment
+    async fn read_file(&self, path: &Path) -> Result<String>;
+    
+    /// Write a file to the environment
+    async fn write_file(&self, path: &Path, content: &str) -> Result<()>;
+    
+    /// List directory contents
+    async fn list_dir(&self, path: &Path) -> Result<Vec<DirEntry>>;
+    
+    /// Execute a command
+    async fn exec(&self, command: &str, args: &[&str]) -> Result<ExecResult>;
+    
+    /// Check if path exists
+    async fn exists(&self, path: &Path) -> Result<bool>;
+    
+    /// Get environment info (working directory, OS, etc.)
+    async fn env_info(&self) -> Result<EnvInfo>;
+    
+    /// Open a bidirectional stream (for LSP, etc.)
+    async fn open_stream(&self, target: &str) -> Result<Box<dyn AsyncStream>>;
+}
+
+pub struct ExecResult {
+    pub exit_code: i32,
+    pub stdout: String,
+    pub stderr: String,
+}
+
+pub struct EnvInfo {
+    pub working_dir: PathBuf,
+    pub os: String,
+    pub hostname: String,
+    /// Trust level of this connector
+    pub trust_level: TrustLevel,
+}
+```
+
+### Trust Levels
+
+Different input sources have different trust levels:
+
+```rust
+pub enum TrustLevel {
+    /// Partner's own environment - full trust
+    /// CLI, remote connector authenticated as partner
+    Partner,
+    
+    /// Known friend/collaborator - high trust
+    /// Could allow some file operations
+    Friend,
+    
+    /// Public conversant - limited trust
+    /// Discord/Bluesky strangers
+    Conversant,
+    
+    /// Untrusted - read-only, sandboxed
+    Untrusted,
+}
+```
+
+Trust level affects what tools the agent can use:
+
+```rust
+impl Agent {
+    fn allowed_tools(&self, trust: TrustLevel) -> Vec<Tool> {
+        match trust {
+            TrustLevel::Partner => self.all_tools(),
+            TrustLevel::Friend => self.tools_except(&["shell", "file_write"]),
+            TrustLevel::Conversant => self.safe_tools_only(),
+            TrustLevel::Untrusted => vec![],
+        }
+    }
+}
+```
+
+### Implementations
+
+#### LocalConnector
+
+For when agent runs on same machine:
+
+```rust
+pub struct LocalConnector {
+    working_dir: PathBuf,
+    trust_level: TrustLevel,
+}
+
+#[async_trait]
+impl EnvironmentConnector for LocalConnector {
+    async fn read_file(&self, path: &Path) -> Result<String> {
+        tokio::fs::read_to_string(path).await.map_err(Into::into)
+    }
+    
+    async fn exec(&self, command: &str, args: &[&str]) -> Result<ExecResult> {
+        let output = tokio::process::Command::new(command)
+            .args(args)
+            .current_dir(&self.working_dir)
+            .output()
+            .await?;
+        
+        Ok(ExecResult {
+            exit_code: output.status.code().unwrap_or(-1),
+            stdout: String::from_utf8_lossy(&output.stdout).into(),
+            stderr: String::from_utf8_lossy(&output.stderr).into(),
+        })
+    }
+    
+    // ...
+}
+```
+
+#### RemoteConnector
+
+For when agent runs on server, partner's machine is remote:
+
+```rust
+pub struct RemoteConnector {
+    /// WebSocket or other transport to partner's client
+    transport: Box<dyn Transport>,
+    trust_level: TrustLevel,
+}
+
+#[async_trait]
+impl EnvironmentConnector for RemoteConnector {
+    async fn read_file(&self, path: &Path) -> Result<String> {
+        let request = ConnectorRequest::ReadFile { path: path.to_owned() };
+        let response = self.transport.request(request).await?;
+        match response {
+            ConnectorResponse::FileContent(content) => Ok(content),
+            ConnectorResponse::Error(e) => Err(e.into()),
+            _ => Err(anyhow!("unexpected response")),
+        }
+    }
+    
+    // ...
+}
+```
+
+### Wire Protocol
+
+JSON-RPC style messages over WebSocket:
+
+```rust
+#[derive(Serialize, Deserialize)]
+#[serde(tag = "method", content = "params")]
+pub enum ConnectorRequest {
+    ReadFile { path: PathBuf },
+    WriteFile { path: PathBuf, content: String },
+    ListDir { path: PathBuf },
+    Exec { command: String, args: Vec<String> },
+    Exists { path: PathBuf },
+    EnvInfo,
+    OpenStream { target: String },
+}
+
+#[derive(Serialize, Deserialize)]
+#[serde(tag = "type", content = "data")]
+pub enum ConnectorResponse {
+    FileContent(String),
+    DirEntries(Vec<DirEntry>),
+    ExecResult(ExecResult),
+    Bool(bool),
+    EnvInfo(EnvInfo),
+    StreamOpened { stream_id: String },
+    Error(String),
+}
+```
+
+### Client-Side Daemon
+
+Partner runs a small daemon that:
+1. Connects to Pattern server via WebSocket
+2. Authenticates (proves they're the partner)
+3. Handles `ConnectorRequest`s from their agent
+4. Enforces local security policies
+
+```rust
+// pattern-connector daemon
+async fn main() {
+    let config = load_config()?;
+    
+    let ws = connect_to_server(&config.server_url).await?;
+    authenticate(&ws, &config.credentials).await?;
+    
+    loop {
+        let request: ConnectorRequest = ws.recv().await?;
+        
+        // Check local policy
+        if !policy_allows(&request) {
+            ws.send(ConnectorResponse::Error("denied by policy")).await?;
+            continue;
+        }
+        
+        let response = handle_request(request).await;
+        ws.send(response).await?;
+    }
+}
+```
+
+### Integration with Tools
+
+Agent tools can use the connector:
+
+```rust
+pub struct FileReadTool {
+    connector: Arc<dyn EnvironmentConnector>,
+}
+
+#[async_trait]
+impl Tool for FileReadTool {
+    async fn execute(&self, args: ToolArgs) -> Result<ToolResult> {
+        let path = args.get::<PathBuf>("path")?;
+        let content = self.connector.read_file(&path).await?;
+        Ok(ToolResult::text(content))
+    }
+}
+```
+
+### LSP Integration
+
+For editor integration, the connector can proxy LSP:
+
+```rust
+impl RemoteConnector {
+    async fn connect_lsp(&self, language: &str) -> Result<LspClient> {
+        let stream = self.open_stream(&format!("lsp:{}", language)).await?;
+        Ok(LspClient::new(stream))
+    }
+}
+```
+
+The client-side daemon would spawn the appropriate LSP server and bridge the connection.
+
+## Security Considerations
+
+1. **Authentication** - Connector must prove it's the partner
+   - Could use same auth as API (JWT)
+   - Or separate long-lived connector tokens
+   
+2. **Authorization** - Even partner may want limits
+   - Configurable allowed paths
+   - Command allowlist/denylist
+   - Confirmation prompts for destructive operations
+
+3. **Sandboxing** - For non-partner connectors
+   - Read-only access
+   - No command execution
+   - Limited to specific directories
+
+4. **Audit logging** - Track all connector operations
+   - Who, what, when
+   - Useful for debugging and trust building
+
+## Relationship to ACP
+
+Agent Communication Protocol would use similar transport:
+- Agent A on server X wants to coordinate with Agent B on server Y
+- Each agent has connector access to their partner's environment
+- ACP messages flow server-to-server
+- File/environment access flows through connectors

+## Transport: iroh
+
+**Decision**: Use [iroh](https://iroh.computer/) for connector transport.
+
+### Why iroh
+
+- **Peer-to-peer** - No central relay required (though uses relays for NAT traversal)
+- **Encryption built-in** - QUIC-based, TLS 1.3
+- **Cryptographic identity** - Stable node IDs (public keys) for auth
+- **Rust-native** - `iroh-net`, `iroh-rpc`, `iroh-bytes` crates, async, well-maintained
+- **Handles reconnection** - Connection state management built in
+- **NAT traversal** - STUN/TURN equivalent via n0 discovery
+
+### iroh Protocol Stack
+
+| Layer | iroh Crate | Use in Pattern |
+|-------|------------|----------------|
+| Transport | `iroh-net` | QUIC connections, node identity, NAT traversal |
+| RPC | `iroh-rpc` | Request/response for connector operations |
+| Streaming | `iroh-bytes` | Large file transfers, ACP message streams |
+
+**Primary primitive**: `iroh-rpc` for most connector operations (file read/write, exec, etc.)
+
+**Streaming**: `iroh-bytes` or raw QUIC streams for:
+- Large file transfers (chunked)
+- ACP message proxying
+- LSP bidirectional streams

+### Authentication via Node ID
+
+iroh peers have cryptographic node IDs (public keys). We use this for auth:
+
+```rust
+pub struct ConnectorAuth {
+    /// Partner's iroh node ID (Ed25519 public key)
+    pub partner_node_id: iroh_net::NodeId,
+    
+    /// Constellation this connector is authorized for
+    pub constellation_id: ConstellationId,
+    
+    /// When this auth was established
+    pub paired_at: DateTime<Utc>,
+    
+    /// Optional: human-readable name for this connector
+    pub name: Option<String>,
+}
+
+impl PatternServer {
+    async fn on_connector_connect(&self, conn: iroh_net::Connection) -> Result<()> {
+        let peer_id = conn.remote_node_id();
+        
+        // Check if this node ID is registered
+        match self.db.get_connector_auth(&peer_id).await? {
+            Some(auth) => {
+                // Known partner - create connector
+                let connector = RemoteConnector::new(conn, auth.constellation_id);
+                self.register_connector(auth.constellation_id, connector).await;
+                tracing::info!("Connector {} connected for constellation {}", 
+                    peer_id, auth.constellation_id);

+### Local Policy Configuration

+Partner controls what the connector allows:
+
+```toml
+# ~/.config/pattern-connector/config.toml

+
+### File Change Notifications
+
+Connector can push file change events to the server:
+
+```rust
+#[derive(Serialize, Deserialize)]
+pub enum ConnectorNotification {
+    FileChanged {
+        path: PathBuf,
+        change_type: FileChangeType,

+    FileDeleted {
+        path: PathBuf,
+    },
+    ConnectorStatus {
+        status: ConnectorStatus,
+    },
+}
+
+#[derive(Serialize, Deserialize)]
+pub enum FileChangeType {
+    Modified,
+    Renamed { from: PathBuf },
+}
+
+async fn push_file_changes(
+    conn: &iroh_net::Connection,
+    mut watch_rx: mpsc::Receiver<notify::Event>,
+) -> Result<()> {
+    while let Some(event) = watch_rx.recv().await {
+        let notification = match event.kind {
+            notify::EventKind::Modify(_) => {
+                ConnectorNotification::FileChanged {
+                    path: event.paths[0].clone(),
+                    change_type: FileChangeType::Modified,
+                }
+            }

+            }
+            // ... etc

+        send.finish().await?;
+    }
+    
+    Ok(())
+}
+```
+
+### Reconnection Handling
+
+iroh handles most reconnection automatically, but we add application-level resilience:
+
+```rust
+impl RemoteConnector {
+    async fn request<T: DeserializeOwned>(
+        &self, 
+        req: ConnectorRequest
+    ) -> Result<T> {
+        // Retry with backoff on connection errors
+        let mut attempts = 0;
+        loop {
+            match self.try_request(&req).await {

+                Err(e) if e.is_connection_error() && attempts < 3 => {
+                    attempts += 1;
+                    let backoff = Duration::from_millis(100 * 2u64.pow(attempts));
+                    tokio::time::sleep(backoff).await;
+                    
+                    // iroh may have reconnected automatically
+                    // if not, this will fail again
+                    continue;
+                }
+                Err(e) => return Err(e),
+            }
+        }
+    }
+    
+    /// Check if connector is currently connected
+    pub fn is_connected(&self) -> bool {
+        // iroh connection state
+        !self.conn.close_reason().is_some()
+    }
+    
+    /// Wait for reconnection (iroh handles this)
+    pub async fn wait_connected(&self) -> Result<()> {
+        // iroh will attempt to reconnect automatically
+        // we just need to wait for it
+        tokio::time::timeout(
+            Duration::from_secs(30),
+            self.conn.closed()
+        ).await??;
+        
+        Ok(())
+    }
+}
+```
+
+### Integration with ACP
+
+When Pattern runs as an ACP agent locally, it uses `LocalConnector`. When it runs on a server but the editor is local, we can tunnel ACP over iroh:
+
+```
+┌─────────────────────────────────────────────────────────────────┐
+│                    Partner's Machine                            │
+│                                                                 │
+│  ┌─────────────┐         ┌─────────────────────────────────┐   │

+│  │  - full constellation persistence                       │    │
+│  └────────────────────────────────────────────────────────┘    │
+└─────────────────────────────────────────────────────────────────┘
+```
+
+The connector daemon can spawn a local ACP shim that the editor connects to:
+
+```rust
+// In pattern-connector, optional ACP proxy mode
+async fn run_acp_proxy(
+    conn: &iroh_net::Connection,
+) -> Result<()> {
+    // Spawn local process that speaks ACP over stdio
+    // Forward messages to Pattern server over iroh
+    // Return responses back to editor
+    
+    let mut child = tokio::process::Command::new("pattern-connector")
+        .arg("acp-shim")
+        .stdin(Stdio::piped())
+        .stdout(Stdio::piped())
+        .spawn()?;
+    
+    // Bridge stdio <-> iroh
+    let stdin = child.stdin.take().unwrap();
+    let stdout = child.stdout.take().unwrap();
+    
+    tokio::select! {
+        // Editor -> Server
+        r = forward_stdin_to_iroh(stdout, conn) => r?,
+        // Server -> Editor
+        r = forward_iroh_to_stdout(conn, stdin) => r?,
+    }
+    
+    Ok(())
+}
+```
+
+## Open Questions
+
+1. **LSP multiplexing** - Multiple LSP servers over single iroh connection? Probably separate streams per LSP.
+
+2. **Offline operation** - Cache file contents on server for when connector disconnects?
+   - Could cache recently-accessed files
+   - Mark cached data as potentially stale
+   - Agent sees "connector offline, using cached data from X minutes ago"
+
+3. **Multiple connectors** - Partner with multiple machines. Options:
+   - Route to most-recently-active connector
+   - Route based on request (file path → which machine has it)
+   - Allow agent to specify target connector
+   - Probably: default to most-recent, allow explicit targeting
+
+4. **Connector discovery** - Use iroh's discovery vs explicit config?
+   - Explicit config is simpler and more secure
+   - Discovery could help with "find my connectors" UX
+   - Leaning toward: explicit config required, discovery as optional convenience
+
+5. **iroh-rpc schema** - Define connector RPC interface formally?
+   - Could generate from protobuf/schema
+   - Or just use serde JSON over iroh-rpc
+   - Leaning toward: start with serde, formalize later if needed

+# V2 Structured Memory Sketch
+
+## Overview
+
+Loro CRDT provides more than just text - it has Lists, Maps, Trees, and Counters. This enables **templated/structured memory blocks** where agents work with semantic structure, not just free-form strings.
+
+**Loro Version:** 1.10.3 (production-ready, 5.2k GitHub stars)
+
+## Loro Container Types
+
+| Type | CRDT Algorithm | Use Case | Key Methods |
+|------|----------------|----------|-------------|
+| `LoroText` | Fugue | Rich text, cursor tracking | `insert()`, `delete()`, `mark()` |
+| `LoroList` | RGA | Ordered items | `push()`, `insert()`, `delete()` |
+| `LoroMap` | LWW | Key-value pairs | `insert()`, `get()`, `delete()` |
+| `LoroTree` | Tree CRDT | Hierarchical data | `create()`, `mov()`, `mov_to()` |
+| `LoroMovableList` | RGA+move | Drag-and-drop lists | `mov()`, `set()` |
+| `LoroCounter` | Increment-only | Numeric tracking | `increment()` (feature-gated) |
+
+## Loro API Basics
+
+```rust
+use loro::{LoroDoc, ExportMode};
+
+// Create document
+let doc = LoroDoc::new();
+
+// Access containers (created on first access)
+let text = doc.get_text("persona");
+let list = doc.get_list("preferences");
+let map = doc.get_map("profile");
+let tree = doc.get_tree("project");
+
+// Text operations
+text.insert(0, "Hello")?;
+text.delete(0, 5)?;
+text.mark(0..5, "bold", true)?;  // Rich text
+
+// List operations
+list.push("item")?;
+list.insert(0, "first")?;
+list.delete(1)?;
+
+// Map operations
+map.insert("name", "Alice")?;
+map.insert("energy", 7)?;
+map.delete("energy")?;
+
+// Nested containers
+map.insert_container("tags", LoroList::new())?;
+
+// Persistence
+let snapshot = doc.export(ExportMode::Snapshot)?;  // Full state
+let updates = doc.export(ExportMode::update(from_version))?;  // Incremental
+
+// Import (merges automatically)
+doc.import(&peer_bytes)?;
+
+// Time travel
+let checkpoint = doc.state_frontiers();
+doc.checkout(&checkpoint)?;  // Read-only view
+doc.checkout_to_latest()?;   // Return to head
+```
+
+**Important:** LoroDoc owns all containers. Keep doc alive as long as containers are used.
+
+## Block Schema Concept
+
+Instead of all blocks being opaque text, blocks can have **schemas** that define their structure:
+
+```rust
+/// Block schema defines the structure of a memory block's Loro document
+pub enum BlockSchema {
+    /// Free-form text (default, backward compatible)
+    Text,
+
+    /// Key-value pairs with optional field definitions
+    Map {
+        fields: Vec<FieldDef>,
+    },
+
+    /// Ordered list of items
+    List {
+        item_schema: Option<Box<BlockSchema>>,
+        max_items: Option<usize>,
+    },
+
+    /// Rolling log (list with auto-trim)
+    Log {
+        max_entries: usize,
+        entry_schema: LogEntrySchema,
+    },
+
+    /// Hierarchical tree
+    Tree {
+        node_schema: Option<Box<BlockSchema>>,
+    },
+
+    /// Custom composite
+    Composite {
+        sections: Vec<(String, BlockSchema)>,
+    },
+}
+
+pub struct FieldDef {
+    pub name: String,
+    pub description: String,
+    pub field_type: FieldType,
+    pub required: bool,
+    pub default: Option<serde_json::Value>,
+}
+
+pub enum FieldType {
+    Text,
+    Number,
+    Boolean,
+    List,
+    Timestamp,
+}
+```
+
+## Example Templates
+
+### Partner Profile (Map)
+
+```rust
+BlockSchema::Map {
+    fields: vec![
+        FieldDef {
+            name: "name".into(),
+            description: "Partner's preferred name".into(),
+            field_type: FieldType::Text,
+            required: false,
+            default: None,
+        },
+        FieldDef {
+            name: "preferences".into(),
+            description: "Known preferences and patterns".into(),
+            field_type: FieldType::List,
+            required: false,
+            default: Some(json!([])),
+        },
+        FieldDef {
+            name: "energy_level".into(),
+            description: "Current energy (1-10)".into(),
+            field_type: FieldType::Number,
+            required: false,
+            default: Some(json!(5)),
+        },
+        FieldDef {
+            name: "current_focus".into(),
+            description: "What they're working on now".into(),
+            field_type: FieldType::Text,
+            required: false,
+            default: None,
+        },
+    ],
+}
+```
+
+### Task List (List)
+
+```rust
+BlockSchema::List {
+    item_schema: Some(Box::new(BlockSchema::Map {
+        fields: vec![
+            FieldDef { name: "title".into(), field_type: FieldType::Text, required: true, .. },
+            FieldDef { name: "done".into(), field_type: FieldType::Boolean, required: true, default: Some(json!(false)), .. },
+            FieldDef { name: "priority".into(), field_type: FieldType::Text, required: false, .. },
+            FieldDef { name: "due".into(), field_type: FieldType::Timestamp, required: false, .. },
+        ],
+    })),
+    max_items: Some(100),
+}
+```
+
+### Activity Log (Log)
+
+```rust
+BlockSchema::Log {
+    max_entries: 50,  // Keep recent 50 in context
+    entry_schema: LogEntrySchema {
+        timestamp: true,
+        agent_id: true,
+        fields: vec![
+            FieldDef { name: "event_type".into(), field_type: FieldType::Text, required: true, .. },
+            FieldDef { name: "description".into(), field_type: FieldType::Text, required: true, .. },
+        ],
+    },
+}
+```
+
+## Agent Operations
+
+With structured blocks, tools can offer semantic operations:
+
+### Context Tool Extensions
+
+```rust
+pub enum ContextOperation {
+    // Existing text operations
+    Append { label: String, content: String },
+    Replace { label: String, find: String, replace: String },
+
+    // New structured operations
+    SetField { label: String, field: String, value: serde_json::Value },
+    AppendToList { label: String, field: Option<String>, item: serde_json::Value },
+    RemoveFromList { label: String, field: Option<String>, index: usize },
+    IncrementCounter { label: String, field: String, delta: i64 },
+
+    // Existing swap operations
+    Archive { label: String, archival_label: Option<String> },
+    Load { archival_label: String, label: Option<String> },
+    Swap { label: String, archival_label: String },
+}
+```
+
+### Tool Descriptions for LLM
+
+```
+context.set_field: Update a specific field in a structured memory block.
+Use for: Setting partner's name, updating energy level, changing current focus.
+Example: set_field(label="human", field="energy_level", value=7)
+
+context.append_to_list: Add an item to a list in a memory block.
+Use for: Adding a new preference, recording a new task, logging an observation.
+Example: append_to_list(label="human", field="preferences", item="Prefers morning check-ins")
+
+context.increment_counter: Increment or decrement a numeric field.
+Use for: Tracking counts, adjusting levels.
+Example: increment_counter(label="human", field="energy_level", delta=-2)
+```
+
+## Context Rendering
+
+Structured blocks render to readable text for LLM context:
+
+### Map Rendering
+```
+<human>
+<!-- Information about the person you're talking to -->
+name: Alice
+energy_level: 7
+current_focus: Refactoring the memory system
+preferences:
+  - Prefers concise responses
+  - Likes code examples
+  - Morning person
+</human>
+```
+
+### List Rendering
+```
+<tasks>
+<!-- Current task list -->
+1. [x] Design block schemas
+2. [ ] Implement Loro wrappers (priority: high)
+3. [ ] Write tests
+4. [ ] Update context tool
+</tasks>
+```
+
+### Log Rendering
+```
+<activity_log>
+<!-- Recent activity (last 10 shown) -->
+[2025-01-23 14:32] Agent processed message about memory design
+[2025-01-23 14:28] Tool executed: context.append (scratchpad)
+[2025-01-23 14:25] Memory updated: human.preferences (added item)
+</activity_log>
+```
+
+## Implementation Considerations
+
+### 1. Schema Storage
+- Schema could be stored in block metadata (JSON)
+- Or schema could be a separate table (reusable templates)
+- Default schema is Text (backward compatible)
+
+### 2. Validation
+- On write: validate value against schema
+- On read: handle schema evolution (missing fields get defaults)
+- Migrations: schema changes should be additive
+
+### 3. Loro Document Structure
+
+For a Map block:
+```rust
+// Each field is a child container
+doc.get_text("name")       // LoroText
+doc.get_list("preferences") // LoroList
+doc.get_map("metadata")     // For extensibility
+```
+
+For a List block:
+```rust
+doc.get_list("items")  // LoroList of LoroMaps (each item)
+```
+
+For a Log block:
+```rust
+doc.get_list("entries")  // LoroList, auto-trimmed on persist
+```
+
+### 4. Backward Compatibility
+- Existing text blocks continue to work (schema = Text)
+- New structured blocks opt-in via schema
+- Migration tool can convert text → structured if needed
+
+### 5. CRDT Benefits
+- **Concurrent edits**: Multiple agents can modify same block
+- **Merge semantics**: List appends merge cleanly, map fields LWW
+- **History**: All changes tracked, rollback possible
+- **Sync**: Future multi-device support
+
+## Open Questions
+
+1. **Schema evolution**: How do we handle schema changes over time?
+2. **Nested structures**: How deep should we allow nesting?
+3. **Custom renderers**: Should blocks define their own context rendering?
+4. **Tool generation**: Can we auto-generate tool operations from schema?
+5. **Validation errors**: How should agents handle schema violations?
+
+## Next Steps
+
+1. Research Loro API in detail (container types, persistence)
+2. Design StructuredDocument wrapper with typed operations
+3. Implement BlockSchema and validation
+4. Extend MemoryStore trait with structured operations
+5. Update context tool with new operations
+6. Create default templates (partner profile, task list, log)

+# ConstellationSearchTool ToolContext Port Regressions
+
+This document tracks functionality lost during the port of `ConstellationSearchTool` from `AgentHandle`-based implementation to `ToolContext`-based implementation (commit 61a6093).
+
+## Overview
+
+The refactoring simplified the tool's implementation by using the new `ToolContext` trait and unified `SearchOptions`, but several important features were lost in the process. These regressions need to be addressed by either:
+1. Extending `SearchOptions` to support the missing parameters
+2. Adding new methods to `ToolContext` for advanced search capabilities
+3. Re-implementing lost logic in the tool itself
+
+---
+
+## Regression 1: Score Adjustment Logic Lost
+
+### What Was Lost
+The old implementation used `process_constellation_results()` from `search_utils.rs` which applied `adjust_message_score()` to downrank certain message types:
+- Tool responses: 30% penalty (score × 0.7)
+- Messages with reasoning/tool blocks: Up to 50% penalty based on ratio of non-content blocks
+- Formula: `score *= 1.0 - (non_content_ratio * 0.5)`
+
+### Impact
+- Agents may receive lower-quality search results with too many tool responses or thinking blocks
+- Archive agents designed to search across conversations now lack quality filtering
+- BM25 scores alone don't account for message content type
+
+### Old Code Location
+- `crates/pattern_core/src/tool/builtin/search_utils.rs:7-40` - `adjust_message_score()`
+- `crates/pattern_core/src/tool/builtin/search_utils.rs:171-192` - `process_constellation_results()`
+
+### How to Restore
+**Option A:** Add score adjustment in the tool itself after receiving results
+```rust
+// In search_constellation_messages(), after getting results:
+let mut scored_messages = results;
+for result in &mut scored_messages {
+    if let Some(msg) = get_message_from_id(&result.id).await {
+        result.score = adjust_message_score(&msg, result.score);
+    }
+}
+scored_messages.sort_by(|a, b| b.score.partial_cmp(&a.score).unwrap_or(Equal));
+```
+
+**Option B:** Extend `MemorySearchResult` to include message metadata
+- Add `message_type` field to distinguish tool/reasoning/content
+- Apply adjustments in MemoryCache/MemoryStore before returning
+
+**Option C:** Add post-processing filter to SearchOptions
+- New field: `apply_content_scoring: bool`
+- Let the database layer handle score adjustments
+
+---
+
+## Regression 2: Metadata Lost in Output
+
+### What Was Lost
+Old archival search included rich metadata:
+```json
+{
+    "label": "user_preferences",
+    "content": "...",
+    "created_at": "2024-01-01T00:00:00Z",
+    "updated_at": "2024-01-01T00:00:00Z",
+    "relevance_score": 0.85
+}
+```
+
+Old message search included:
+```json
+{
+    "agent": "Archive",
+    "id": "msg_123",
+    "role": "assistant",
+    "content": "...",
+    "created_at": "2024-01-01T00:00:00Z",
+    "relevance_score": 0.92
+}
+```
+
+New implementation only returns:
+```json
+{
+    "id": "...",
+    "content": "...",
+    "relevance_score": 0.85
+}
+```
+
+### Impact
+- Archive agents can't see which archival memory label results came from
+- Can't determine which agent said what in constellation searches
+- Can't filter or sort by time since timestamps are missing
+- Reduced context awareness for intelligent follow-up queries
+
+### How to Restore
+**Option A:** Enrich MemorySearchResult type
+```rust
+pub struct MemorySearchResult {
+    pub id: String,
+    pub content_type: SearchContentType,
+    pub content: Option<String>,
+    pub score: f64,
+    // NEW FIELDS:
+    pub label: Option<String>,        // For blocks/archival
+    pub agent_id: Option<String>,     // Which agent owns this
+    pub agent_name: Option<String>,   // Display name
+    pub role: Option<String>,         // For messages: user/assistant/tool
+    pub created_at: Option<DateTime<Utc>>,
+    pub updated_at: Option<DateTime<Utc>>,
+}
+```
+
+**Option B:** Separate result types per content type
+- `BlockSearchResult`, `ArchivalSearchResult`, `MessageSearchResult`
+- Each with appropriate metadata
+- Tool combines them into final output
+
+**Option C:** Make MemoryStore return full entities
+- Change search methods to return full `ArchivalEntry` or message types
+- Let tools extract what they need for display
+
+---
+
+## Regression 3: Fuzzy Parameter Ignored
+
+### What Was Lost
+Old implementation converted the `fuzzy: bool` parameter to `fuzzy_level: Option<i32>`:
+```rust
+let fuzzy_level = if fuzzy { Some(1) } else { None };
+match self.handle.search_archival_memories_with_options(query, limit, fuzzy_level).await
+```
+
+New implementation prefixes with `_fuzzy` and always uses `SearchMode::Fts`:
+```rust
+async fn search_local_archival(&self, query: &str, limit: usize, _fuzzy: bool)
+```
+
+### Impact
+- Fuzzy search feature completely disabled
+- No typo tolerance in searches
+- Parameter accepted but silently ignored (confusing for users)
+
+### How to Restore
+**Option A:** Add fuzzy mode to SearchOptions
+```rust
+pub struct SearchOptions {
+    pub mode: SearchMode,
+    pub fuzzy_level: Option<i32>,  // NEW: 0=exact, 1=some tolerance, 2=high tolerance
+    pub content_types: Vec<SearchContentType>,
+    pub limit: usize,
+}
+```
+
+**Option B:** Extend SearchMode enum
+```rust
+pub enum SearchMode {
+    Fts,
+    FtsFuzzy(i32),  // NEW: FTS with fuzzy level
+    Vector,
+    Hybrid,
+    Auto,
+}
+```
+
+**Option C:** Wait for SurrealDB fuzzy functions
+- Document that fuzzy is not yet implemented
+- Remove the parameter or make it explicit it's a placeholder
+- Add comment referencing issue/plan for implementation
+
+---
+
+## Regression 4: Role and Time Filtering Lost
+
+### What Was Lost
+Old implementation parsed and used role/time parameters:
+```rust
+async fn search_constellation_messages(
+    &self,
+    query: &str,
+    role: Option<ChatRole>,         // Used in database query
+    start_time: Option<DateTime<Utc>>, // Used in database query
+    end_time: Option<DateTime<Utc>>,   // Used in database query
+    limit: usize,
+    fuzzy: bool,
+)
+```
+
+New implementation parses but prefixes with `_` (ignored):
+```rust
+async fn search_constellation_messages(
+    &self,
+    query: &str,
+    _role: Option<ChatRole>,          // IGNORED
+    _start_time: Option<DateTime<Utc>>, // IGNORED
+    _end_time: Option<DateTime<Utc>>,   // IGNORED
+    limit: usize,
+    _fuzzy: bool,
+)
+```
+
+### Impact
+- Can't filter messages by role (user/assistant/tool)
+- Can't limit search to time ranges
+- Tool accepts parameters but doesn't use them (confusing UX)
+- Archive agents lose important filtering capabilities
+
+### Current Status
+Has TODO comment at line 379-380:
+```rust
+// TODO: ToolContext doesn't currently expose role/time filtering for message search
+// Need to add these parameters to SearchOptions once message search is fully integrated
+```
+
+### How to Restore
+**Extend SearchOptions with filter fields:**
+```rust
+pub struct SearchOptions {
+    pub mode: SearchMode,
+    pub content_types: Vec<SearchContentType>,
+    pub limit: usize,
+    // NEW FIELDS:
+    pub role_filter: Option<ChatRole>,
+    pub start_time: Option<DateTime<Utc>>,
+    pub end_time: Option<DateTime<Utc>>,
+}
+```
+
+Then update pattern_db search functions to use these filters in WHERE clauses.
+
+---
+
+## Regression 5: search_all Limit Behavior Changed
+
+### What Was Lost
+Old implementation searched each domain with the full limit:
+```rust
+async fn search_all(&self, query: &str, limit: usize, fuzzy: bool) {
+    let archival_result = self.search_local_archival(query, limit, fuzzy).await?;  // Up to `limit` results
+    let conv_result = self.search_constellation_messages(query, None, None, None, limit, fuzzy).await?; // Up to `limit` results
+    // Could return up to 2×limit total results
+}
+```
+
+New implementation searches both with a shared limit:
+```rust
+async fn search_all(&self, query: &str, limit: usize, _fuzzy: bool) {
+    let options = SearchOptions {
+        mode: SearchMode::Fts,
+        content_types: vec![SearchContentType::Archival, SearchContentType::Messages],
+        limit, // Single limit shared across both types
+    };
+    // Returns up to `limit` total results (not per type)
+}
+```
+
+### Impact
+- Archive agents get fewer total results when searching "all"
+- If limit=30, old returned up to 60 results (30 archival + 30 messages)
+- New returns up to 30 results total (maybe 15 archival + 15 messages)
+- Reduced information density for comprehensive searches
+
+### How to Restore
+**Option A:** Add `limit_per_type: bool` to SearchOptions
+```rust
+pub struct SearchOptions {
+    pub limit: usize,
+    pub limit_per_type: bool, // If true, apply limit to each content type separately
+}
+```
+
+**Option B:** Separate the searches like before
+```rust
+async fn search_all(&self, query: &str, limit: usize) {
+    let archival_opts = SearchOptions::new().archival_only().limit(limit);
+    let msg_opts = SearchOptions::new().messages_only().limit(limit);
+
+    let archival = self.ctx.search(query, Constellation, archival_opts).await?;
+    let messages = self.ctx.search(query, Constellation, msg_opts).await?;
+
+    // Combine up to 2×limit results
+}
+```
+
+**Option C:** Document as intentional change
+- New behavior may be better (balanced results)
+- Old behavior could overwhelm with too many results
+- If keeping new behavior, update documentation/examples
+
+---
+
+## Regression 6: Progressive Truncation Limits Changed
+
+### What Was Lost
+Old implementation had different truncation limits for constellation vs local search:
+
+**Constellation search** (group_archival):
+```rust
+let content = if i < 5 {
+    sb.block.value.clone()  // Full content for top 5
+} else if i < 15 {
+    extract_snippet(&sb.block.value, query, 1500)  // 1500 chars
+} else {
+    extract_snippet(&sb.block.value, query, 800)   // 800 chars
+};
+```
+
+**Local search** (local_archival):
+```rust
+let content = if i < 2 {
+    sb.block.value.clone()  // Full content for top 2
+} else if i < 5 {
+    extract_snippet(&sb.block.value, query, 1000)  // 1000 chars
+} else {
+    extract_snippet(&sb.block.value, query, 400)   // 400 chars
+};
+```
+
+New implementation uses the same limits everywhere:
+```rust
+let content = r.content.as_ref().map(|c| {
+    if i < 2 {
+        c.clone()
+    } else if i < 5 {
+        extract_snippet(c, query, 1000)  // Always 1000
+    } else {
+        extract_snippet(c, query, 400)   // Always 400
+    }
+});
+```
+
+### Impact
+- Constellation archival search now shows less content (1000 vs 1500 chars for mid-range results, 400 vs 800 for lower results)
+- Archive agents were specifically designed for comprehensive constellation searches with longer snippets
+- May reduce effectiveness for Archive agent's primary use case
+
+### How to Restore
+**Option A:** Restore constellation-specific limits in search_group_archival
+```rust
+async fn search_group_archival(&self, ...) {
+    // After getting results:
+    let formatted: Vec<_> = results.iter().enumerate().map(|(i, r)| {
+        let content = r.content.as_ref().map(|c| {
+            if i < 5 { c.clone() }
+            else if i < 15 { extract_snippet(c, query, 1500) }  // Constellation-specific
+            else { extract_snippet(c, query, 800) }
+        });
+        // ...
+    }).collect();
+}
+```
+
+**Option B:** Make truncation limits configurable
+- Add to ConstellationSearchInput or SearchOptions
+- Different tools/agents can specify their preferred verbosity
+
+**Option C:** Document as intentional simplification
+- Unified behavior is easier to maintain
+- If performance is acceptable, keep it simple
+
+---
+
+## Regression 7: search_archival_in_memory() Removed
+
+### What Was Lost
+Old implementation had a fallback method for in-memory searching:
+```rust
+fn search_archival_in_memory(&self, query: &str, limit: usize) -> Result<SearchOutput> {
+    let query_lower = query.to_lowercase();
+    let mut results: Vec<_> = self.handle.memory
+        .get_all_blocks()
+        .into_iter()
+        .filter(|block| {
+            block.memory_type == crate::memory::MemoryType::Archival
+                && block.value.to_lowercase().contains(&query_lower)
+        })
+        .take(limit)
+        .map(|block| {
+            json!({
+                "label": block.label,
+                "content": block.value,
+                "created_at": block.created_at,
+                "updated_at": block.updated_at
+            })
+        })
+        .collect();
+
+    results.sort_by(|a, b| {
+        let a_time = a.get("updated_at").and_then(|v| v.as_str()).unwrap_or("");
+        let b_time = b.get("updated_at").and_then(|v| v.as_str()).unwrap_or("");
+        b_time.cmp(a_time)
+    });
+
+    Ok(SearchOutput { ... })
+}
+```
+
+Called as fallback when database search failed:
+```rust
+match self.handle.search_archival_memories_with_options(...).await {
+    Ok(scored_blocks) => { /* Use DB results */ }
+    Err(e) => {
+        tracing::warn!("Database search failed, falling back to in-memory: {}", e);
+        self.search_archival_in_memory(query, limit)
+    }
+}
+```
+
+### Impact
+- No fallback when database search fails
+- Tools completely fail instead of degrading gracefully
+- In-memory-only agents (tests, demos) can't use search at all
+- Reduced resilience
+
+### How to Restore
+**Option A:** Add in-memory search to MemoryStore trait
+```rust
+#[async_trait]
+pub trait MemoryStore {
+    // ... existing methods ...
+
+    /// Fallback search using only in-memory cache (no database)
+    async fn search_in_memory(
+        &self,
+        agent_id: &str,
+        query: &str,
+        options: SearchOptions,
+    ) -> MemoryResult<Vec<MemorySearchResult>>;
+}
+```
+
+**Option B:** Make MemoryCache search always work
+- MemoryCache.search() should work even if database is unavailable
+- Return results from cache only, with a warning log
+- Tools automatically get resilience through MemoryStore
+
+**Option C:** Add fallback in the tool itself
+```rust
+match self.ctx.search(query, scope, options).await {
+    Ok(results) => Ok(results),
+    Err(e) if e.is_database_error() => {
+        tracing::warn!("DB search failed, trying memory cache: {}", e);
+        self.search_memory_cache_fallback(query, limit).await
+    }
+    Err(e) => Err(e),
+}
+```
+
+---
+
+## Summary Table
+
+| Regression | Severity | Restoration Effort | Recommended Approach |
+|------------|----------|-------------------|---------------------|
+| Score adjustment logic | High | Medium | Option A: Post-process in tool |
+| Metadata lost | High | Medium | Option A: Extend MemorySearchResult |
+| Fuzzy parameter ignored | Low | Low | Option C: Document as TODO |
+| Role/time filtering | High | Medium | Extend SearchOptions (per TODO) |
+| search_all limit changed | Medium | Low | Option B: Separate searches |
+| Truncation limits changed | Low | Low | Option A: Restore constellation-specific |
+| In-memory fallback removed | Medium | Medium | Option B: Make MemoryCache resilient |
+
+---
+
+## Next Steps
+
+1. **Priority 1 (P1):** Role/time filtering in SearchOptions
+   - Already has TODO comment
+   - Critical for Archive agent functionality
+   - Needed for time-based queries
+
+2. **Priority 1 (P1):** Restore metadata in search results
+   - Archive agents need to know which agent/label results came from
+   - Timestamps needed for temporal awareness
+   - Labels needed for context tool integration
+
+3. **Priority 2 (P2):** Score adjustment logic
+   - Quality of search results significantly impacted
+   - Can be implemented as post-processing step
+   - Doesn't require SearchOptions changes
+
+4. **Priority 2 (P2):** search_all limit behavior
+   - Quick fix, restore old behavior for comprehensive searches
+   - Important for Archive agent's primary use case
+
+5. **Priority 3 (P3):** In-memory fallback
+   - Affects resilience and testing
+   - Can be addressed by making MemoryCache more robust
+
+6. **Priority 3 (P3):** Progressive truncation limits
+   - Low impact, mostly affects display
+   - Easy to restore constellation-specific limits
+
+7. **Priority 4 (P4):** Fuzzy search parameter
+   - Already documented as placeholder in code
+   - Wait for SurrealDB fuzzy functions

-# SurrealDB Integration Issues
-
-This document provides quick solutions to common SurrealDB integration problems in Pattern.
-
-## Quick Reference
-
-For detailed explanations and examples, see [SurrealDB Integration Gotchas](../dev-logs/2025-01-07-surreal-db-gotchas.md).
-
-## Common Errors and Solutions
-
-### FieldCheck Error: "expected a datetime"
-
-**Error:**
-```
-FieldCheck { thing: "user:⟨uuid⟩", value: "'2025-01-07T19:20:40Z'", field: Idiom([Field(Ident("created_at"))]), check: "datetime" }
-```
-
-**Solution:** Use `surrealdb::Datetime` instead of serializing to JSON:
-```rust
-// Wrong
-serde_json::json!({ "created_at": chrono::Utc::now() })
-
-// Right
-struct DbModel {
-    created_at: surrealdb::Datetime,
-}
-```
-
-### IdMismatch Error
-
-**Error:**
-```
-IdMismatch { value: "agent:⟨uuid⟩" }
-```
-
-**Solution:** Pass UUID as string, not UUID type:
-```rust
-// Wrong
-DB.create((AgentIdType::PREFIX, id.uuid()))
-
-// Right
-DB.create((AgentIdType::PREFIX, id.uuid().to_string()))
-```
-
-### Invalid UUID Format
-
-**Error:**
-```
-Error(Char { character: '⟨', index: 1 })
-```
-
-**Solution:** Strip the `⟨⟩` characters when parsing:
-```rust
-pub fn strip_brackets(s: &str) -> &str {
-    s.strip_prefix('⟨')
-        .and_then(|s| s.strip_suffix('⟩'))
-        .unwrap_or(s)
-}
-```
-
-### AlreadyConnected Error in Tests
-
-**Error:**
-```
-ConnectionFailed(Api(AlreadyConnected))
-```
-
-**Solution:** Use the extension trait pattern with isolated test databases:
-```rust
-// In tests - create isolated instance
-let db = any::connect("memory").await.unwrap();
-db.use_ns("test").use_db("test").await.unwrap();
-```
-
-### InvalidUrl for Embedded Database
-
-**Error:**
-```
-ConnectionFailed(Api(InvalidUrl("/path/to/db")))
-```
-
-**Solution:** Use proper path format:
-```rust
-// For file-based
-format!("surrealkv://{}", path)
-
-// For in-memory
-"memory"
-```
-
-## Database Schema Best Practices
-
-### DO NOT Define ID Fields as anything other than 'record' type
-
-```sql
--- Wrong
-DEFINE FIELD id ON user TYPE uuid;
-
--- Right (let SurrealDB manage IDs)
-DEFINE FIELD created_at ON user TYPE datetime;
-
--- Right (use the right type if you must be explicit)
-DEFINE FIELD id ON user TYPE record;
-```
-
-### Use Proper Field Types
-
-```sql
-DEFINE FIELD created_at ON table TYPE datetime;  -- Not string!
-    -- And also not chrono::DateTime either! fmt string for parsing is "d'%FT%T%.6fZ'"
-DEFINE FIELD metadata ON table TYPE object;      -- For JSON data
-DEFINE FIELD user_id ON table TYPE record<user>; -- For relations
-```
-
-## Testing Strategies
-
-### Extension Trait Pattern (Recommended)
-
-Create an extension trait that works with both global and local instances:
-```rust
-pub trait SurrealExt<C>
-where
-    C: surrealdb::Connection,
-{
-    async fn create_user(&self, /* params */) -> Result<User>;
-}
-
-impl<T, C> SurrealExt<C> for T
-where
-    T: AsRef<surrealdb::Surreal<C>>,
-    C: surrealdb::Connection,
-{
-    // Implementation
-}
-
-// In tests
-#[tokio::test]
-async fn test_operations() {
-    let db = any::connect("memory").await.unwrap();
-    db.use_ns("test").use_db("test").await.unwrap();
-    // Each test gets its own isolated database!
-}
-```

-# SurrealDB Query Patterns
-
-This document covers common patterns and gotchas when working with SurrealDB in the Pattern project.
-
-## Response Handling with `.take()`
-
-The `surrealdb::Response::take()` method is used to extract results from queries, but it has some important behaviors to understand:
-
-### Basic Usage
-
-```rust
-let mut response = db.query("SELECT * FROM user").await?;
-let users: Vec<User> = response.take(0)?; // Take from first query
-```
-
-### Multiple Queries
-
-When you send multiple queries, each has its own index:
-
-```rust
-let mut response = db
-    .query("SELECT * FROM user WHERE name = 'John'")  // Index 0
-    .query("SELECT * FROM task WHERE status = 'pending'") // Index 1
-    .await?;
-
-let johns: Vec<User> = response.take(0)?;
-let tasks: Vec<Task> = response.take(1)?;
-```
-
-### Nested Results (Common Gotcha!)
-
-When queries return nested structures, you might get a `Vec<Vec<T>>` instead of `Vec<T>`:
-
-```rust
-// This DELETE query returns [[{ affected: 1 }]]
-let delete_query = "DELETE user:123";
-let mut response = db.query(delete_query).await?;
-
-// WRONG: This will fail with deserialization error
-let result: Vec<serde_json::Value> = response.take(0)?;
-
-// CORRECT: Handle the nested structure
-let result: Vec<Vec<serde_json::Value>> = response.take(0)?;
-let affected = result[0][0]["affected"].as_u64().unwrap_or(0);
-```
-
-### Field Extraction
-
-You can extract specific fields using tuple syntax:
-
-```rust
-let mut response = db.query("SELECT id, name, email FROM user").await?;
-
-// Extract just the IDs
-let ids: Vec<String> = response.take("id")?;
-
-// Or from a specific query index
-let names: Vec<String> = response.take((0, "name"))?;
-```
-
-## DELETE Operations
-
-### Using the Database Delete Method
-
-The simplest way to delete records is using the database's delete method:
-
-```rust
-// Delete a specific record using RecordId::from() for proper formatting
-db.delete(RecordId::from(user_id)).await?;
-
-// Or with table prefix
-db.delete(("user", user_id.uuid().to_string())).await?;
-```
-
-### Delete with Raw Queries
-
-For conditional deletes or complex operations:
-
-```rust
-// Delete records matching a condition
-db.query("DELETE task WHERE status = 'completed' AND created_at < time::now() - 30d")
-    .await?;
-
-// Delete specific record with query
-let query = format!("DELETE {}", RecordId::from(user_id));
-db.query(&query).await?;
-```
-
-### Key Pattern: Always Use RecordId::from()
-
-When deleting specific records, always use `RecordId::from()` on the ID field:
-
-```rust
-// CORRECT: RecordId::from() handles formatting
-db.delete(RecordId::from(agent.id)).await?;
-
-// AVOID: Manual formatting is error-prone
-let query = format!("DELETE agent:{}", agent.id.uuid().to_string());
-```
-
-## Live Query Patterns
-
-### Watching Specific Records
-
-```rust
-// Watch a single record
-let stream = db
-    .select((UserIdType::PREFIX, user_id.uuid().to_string()))
-    .live()
-    .await?;
-```
-
-### Watching with Conditions
-
-For efficient live queries on collections with conditions, consider adding array fields to enable direct filtering:
-
-```rust
-// Instead of watching a junction table:
-// LIVE SELECT out.* FROM agent_memories WHERE in = $agent_id
-
-// Add an agents array to memory blocks:
-// DEFINE FIELD agents ON mem TYPE array<record<agent>> DEFAULT [];
-
-// Then watch directly (note: no parameters in WHERE clause!)
-let query = format!("LIVE SELECT * FROM mem WHERE {} IN agents", RecordId::from(agent_id));
-```
-
-### Parameter Limitations in LIVE SELECT
-
-**Important**: You cannot use parameters in the WHERE clause of LIVE SELECT queries:
-
-```rust
-// WRONG: Parameters not allowed in WHERE clause
-let query = "LIVE SELECT * FROM person WHERE age > $min_age";
-db.query(query).bind(("min_age", 18)).await?; // This won't work!
-
-// CORRECT: Build the query string with format!
-let min_age = 18;
-let query = format!("LIVE SELECT * FROM person WHERE age > {}", min_age);
-db.query(&query).await?;
-
-// OK: Parameters allowed for table reference
-let query = "LIVE SELECT * FROM $table WHERE age > 18";
-db.query(query).bind(("table", "person")).await?;
-```
-
-When building queries with `format!()`, always sanitize user input to prevent injection attacks.
-
-### Processing Live Query Notifications
-
-```rust
-use futures::StreamExt;
-use surrealdb::{Notification, Action};
-
-while let Some(notification) = stream.next().await {
-    match notification {
-        Ok(Notification { action, data, .. }) => {
-            match action {
-                Action::Create => {
-                    // New record created
-                },
-                Action::Update => {
-                    // Record updated
-                },
-                Action::Delete => {
-                    // Record deleted
-                },
-                _ => {
-                    // Action is non-exhaustive, handle unknown variants
-                }
-            }
-        }
-        Err(e) => {
-            tracing::error!("Live query error: {}", e);
-        }
-    }
-}
-```
-
-## Transaction Patterns
-
-### Ensuring Atomic Operations
-
-When you need multiple operations to succeed or fail together:
-
-```rust
-let query = r#"
-    BEGIN TRANSACTION;
-    
-    -- Create the memory block
-    CREATE mem:$mem_id SET
-        owner_id = $owner_id,
-        label = $label,
-        content = $content;
-    
-    -- Attach to agent with access level
-    RELATE $agent_id->agent_memories->$mem_id
-        SET access_level = 'write';
-    
-    -- Update the agents array
-    UPDATE $mem_id SET agents += $agent_id;
-    
-    COMMIT TRANSACTION;
-"#;
-
-db.query(query)
-    .bind(("mem_id", RecordId::from(memory_id)))
-    .bind(("owner_id", RecordId::from(owner_id)))
-    .bind(("agent_id", RecordId::from(agent_id)))
-    .bind(("label", label))
-    .bind(("content", content))
-    .await?;
-```
-
-## Common Gotchas
-
-### 1. UUID Format in Record IDs
-
-Always use `RecordId::from()` to handle ID formatting:
-
-```rust
-// BEST: Use the delete method with RecordId
-db.delete(RecordId::from(memory_id)).await?;
-
-// GOOD: RecordId handles formatting in queries
-let query = format!("DELETE {}", RecordId::from(memory_id));
-
-// AVOID: Manual UUID formatting is error-prone
-let query = format!("DELETE mem:{}", memory_id.uuid().to_string().replace('-', "_"));
-```
-
-### 2. RELATE Queries Don't Update Existing Records
-
-The `RELATE` query creates junction records but doesn't update the related records themselves. If you need to maintain denormalized data (like an agents array), update it separately:
-
-```rust
-// Create the relationship
-db.query("RELATE $agent->agent_memories->$memory SET access_level = 'read'")
-    .bind(("agent", RecordId::from(agent_id)))
-    .bind(("memory", RecordId::from(memory_id)))
-    .await?;
-
-// Also update the denormalized array
-db.query("UPDATE $memory SET agents += $agent WHERE $agent NOT IN agents")
-    .bind(("memory", RecordId::from(memory_id)))
-    .bind(("agent", RecordId::from(agent_id)))
-    .await?;
-```
-
-### 3. Empty Results vs Errors
-
-SurrealDB returns empty results for queries that match nothing, not errors:
-
-```rust
-let mut response = db.query("SELECT * FROM user:nonexistent").await?;
-let user: Option<User> = response.take(0)?; // This is None, not an error
-```
-
-### 4. Live Queries and Junction Tables
-
-Live queries on junction tables don't fire when the related records change, only when the junction itself changes. For real-time updates on related data, watch the actual data tables with appropriate filters.
-
-## Structured Record IDs (Experimental)
-
-### Array-Based IDs
-
-SurrealDB supports complex ID types including arrays and objects, which can be useful for encoding metadata directly in the ID:
-
-```rust
-// Example: weather:['London', d'2025-02-14T01:52:50.375Z']
-// This allows natural sorting and efficient range queries
-```
-
-We experimented with using array-based IDs for MessageId to encode `[datetime, api_id, agent_id?]` but encountered issues with:
-- Double-encoding when storing/retrieving through the Entity macro
-- Complex array keys not working reliably with SurrealDB beta
-- Serialization/deserialization edge cases
-
-**Current Status**: Reverted to simple string IDs for MessageId. The implementation challenges outweighed the benefits for now.
-
-### Alternative Approaches
-
-For more comprehensive SurrealDB helper functionality, consider these community crates:
-
-- **surrealdb-extras**: A proc macro helper crate that provides additional functionality for working with SurrealDB: https://github.com/frederik-uni/surrealdb-extras
-  - More sophisticated entity mapping
-  - Advanced query builders
-  - Additional type safety features
-
-- **surreal_derive_plus**: Another derive macro crate for SurrealDB: https://crates.io/crates/surreal_derive_plus
-  - Enhanced derive macros for SurrealDB models
-  - Automatic query generation
-  - Relationship handling
-
-These could be worth investigating in the future as SurrealDB matures and stabilizes its array/object ID support.
-
-## Best Practices
-
-1. **Use RecordId::from()**: Always convert typed IDs with `RecordId::from()` for database operations
-2. **Prefer Database Methods**: Use `db.delete()`, `db.select()`, etc. over raw queries when possible
-3. **LIVE SELECT Parameters**: Remember parameters only work for table names, not WHERE clauses
-4. **Sanitize Format Strings**: When using `format!()` for LIVE queries, sanitize user input
-5. **Handle Nested Responses**: Be aware that some queries return nested structures
-6. **Use Transactions**: For multi-step operations that must be atomic
-7. **Index Array Fields**: When using arrays for filtering (like `agents` on memory blocks)
-8. **Test Live Queries**: Always test that your live queries fire on the expected changes
