Store Selection for Cognitive Mesh + +**Status:** Accepted +**Date:** 2026-02-21 +**Decision Makers:** Architecture Team +**Context:** MetacognitiveLayer Memory Subsystem + +--- + +## Context + +Cognitive Mesh requires a memory subsystem that serves two distinct purposes: + +1. **Session Context Memory** (MetacognitiveLayer) - Transient key-value storage for conversation sessions with vector similarity search for embedding retrieval +2. **Episodic Memory** (ReasoningLayer) - Long-term cognitive memory with multi-strategy recall (exact, fuzzy, semantic, temporal, hybrid) + +The current architecture uses: +- **HybridMemoryStore** wrapping Redis (hot cache + vector search) and DuckDB (persistent OLAP fallback) +- **MemoryStrategyEngine** using in-memory `ConcurrentDictionary` for episodic memory (no persistence) + +### Problems with Current Implementation + +| Problem | Impact | +|---------|--------| +| DuckDB requires native library (`DuckDB.NET.Data`) that complicates CI/CD | Build failures, stub classes needed | +| Episodic memory is entirely in-memory | Data lost on restart, no multi-instance sharing | +| Write amplification in HybridMemoryStore (2x writes) | Increased

(cloud deployments) | + +--- + +## Decision + +### Tier 1: Implement Now + +1. **SQLite** (via `Microsoft.Data.Sqlite`) as the embedded persistent store, replacing DuckDB + - Zero native dependency issues (built into .NET SDK) + - ACID transactions for consistency + - WAL mode for concurrent reads + - Eliminates DuckDB stub workaround + - Manual cosine similarity in C# for vector search (acceptable at <100k records) + +2. **Qdrant integration** for production vector search (enhance existing FoundationLayer adapter) + - Already has `QdrantVectorDatabaseAdapter` in FoundationLayer + - Wire into `MemoryStoreFactory` as a selectable `IVectorSearchProvider` + - Replace Redis-only vector search with Qdrant option + +### Tier 2: Keep As-Is + +3. **Redis** remains as the hot cache layer + - Sub-millisecond reads for active sessions + - Keep Redis Search for environments that have Redis Stack + - TTL support for automatic session expiration + +4. **ConcurrentDictionary** remains for MemoryStrategyEngine + - Add optional SQLite persistence backend for episodic memory + - Lazy-load from SQLite on startup, write-through on changes + +### Tier 3: Future Consideration + +5. **PostgreSQL + pgvector** for cloud-native deployments + - Implement when Azure deployment is prioritized + - Can replace both SQLite and Redis in cloud environments + +--- + +## Implementation Plan + +### Phase 1: SQLite Memory Store (Replace DuckDB) +- Create `SqliteMemoryStore : IMeshMemoryStore` adapter +- Implement context table with UPSERT semantics +- Implement embeddings table with manual cosine similarity +- Update `MemoryStoreFactory` to support `"sqlite"` store type +- Add `Microsoft.Data.Sqlite` to `Protocols.csproj` +- Remove DuckDB stub classes + +### Phase 2: Qdrant Vector Search Provider +- Create `QdrantVectorSearchProvider : IVectorSearchProvider` adapter +- Wire into `MemoryStoreFactory` for `IVectorSearchProvider` registration +- Support configurable collection names and vector dimensions +- Add fallback from Qdrant to SQLite for offline/development scenarios + +### Phase 3: Configuration & Factory Updates +- Add `VectorSearchProvider` option: `"redis"` | `"qdrant"` | `"sqlite"` +- Add `EpisodicPersistence` option: `"memory"` | `"sqlite"` +- Update `MemoryStoreOptions` with new configuration +- Update DI registration in `MemoryStoreFactory` + +--- + +## Consequences + +### Positive +- Eliminates DuckDB native dependency (CI/CD simplification) +- ACID transactions for persistent memory operations +- Production-grade vector search via Qdrant +- Configurable backend selection per deployment environment +- No breaking changes to `IMeshMemoryStore` interface + +### Negative +- SQLite vector search is slower than Redis/Qdrant (acceptable for fallback) +- Additional adapter code to maintain +- Qdrant requires external service for production vector search + +### Risks +- SQLite WAL mode has a single-writer limitation (mitigated by short write duration) +- Qdrant service availability depends on deployment infrastructure +- Migration from DuckDB schema to SQLite schema needs careful data handling + +--- + +## References + +-

UI project, including the design system, component development, and documentation. + +## Design System Workflow + +### 1. Working with Design Tokens + +The project uses **Style Dictionary** to manage design tokens across multiple platforms. + +#### Token Structure +``` +tokens/ +├── colors.json # Color tokens (primary, secondary, semantic) +├── typography.json # Font families, sizes, weights, line heights +├── spacing.json # Spacing scale +└── [new-tokens].json # Additional token categories +``` + +#### Adding New Tokens +1. **Edit token files** in the `tokens/` directory +2. **Build tokens**: `npm run tokens` +3. **Use in components**: Import generated CSS variables + +#### Example: Adding a new color token +```json +// tokens/colors.json +{ + "color": { + "cognitive": { + "accent": { + "new": { "value": "#FF6B9D" } + } + } + } +} +``` + +After running `npm run tokens`, use in CSS: +```css +.my-component { + background: var(--color-cognitive-accent-new); +} +``` + +### 2. Component Development + +#### Creating New Components +1. **Create component directory**: + ``` + src/components/MyComponent/ + ├── MyComponent.tsx + ├── MyComponent.module.css + ├── index.ts + └── MyComponent.stories.tsx + ``` + +2. **Use design tokens** in CSS: + ```css + @import '../../../build/css/_variables.css'; + + .my-component { + font-family: var(--typography-font-family-primary); + padding: var(--spacing-md); + background: var(--color-cognitive-primary-neural); + } + ``` + +3. **Add Storybook stories** for documentation and testing + +#### Component Guidelines +- Use TypeScript for type safety +- Implement proper accessibility (ARIA labels, keyboard navigation) +- Follow the existing component patterns +- Include hover, focus, and disabled states +- Use CSS modules for styling + +### 3. Storybook Documentation + +#### Running Storybook +```bash +npm run storybook +``` +Access at: http://localhost:6006 + +#### Creating Stories +```typescript +// MyComponent.stories.tsx +import type { Meta, StoryObj } from '@storybook/react'; +import { MyComponent } from './MyComponent'; + +const meta: Meta = { + title: 'Design System/MyComponent', + component: MyComponent, + parameters: { + layout: 'centered', + }, + argTypes: { + variant: { + control: { type: 'select' }, + options: ['primary', 'secondary'], + }, + }, + tags: ['autodocs'], +}; + +export default meta; +type Story = StoryObj; + +export const Primary: Story = { + args: { + variant: 'primary', + children: 'Primary Button', + }, +}; +``` + +#### Story Best Practices +- Use descriptive story names +- Include all component variants +- Add interactive controls for props +- Document component usage with descriptions +- Include accessibility information + +### 4. Development Commands + +#### Essential Commands +```bash +# Development +npm run dev # Start Next.js dev server +npm run storybook # Start Storybook +npm run tokens # Build design tokens + +# Building +npm run build # Build Next.js app +npm run build-storybook # Build static Storybook + +# Quality +npm run lint # Run ESLint +``` + +#### Token Development Workflow +1. Edit tokens in `tokens/` directory +2. Run `npm run tokens` to regenerate +3. Check generated files in `build/` directory +4. Update components to use new tokens +5. Test in Storybook + +### 5. File Structure Guidelines + +#### Component Organization +``` +src/components/ +├── ComponentName/ +│ ├── ComponentName.tsx # Main component +│ ├── ComponentName.module.css # Styles +│ ├── index.ts # Exports +│ └── ComponentName.stories.tsx # Documentation +``` + +#### Token Organization +``` +tokens/ +├── colors.json # All color tokens +├── typography.json # All typography tokens +├── spacing.json # All spacing tokens +└── [category].json # Other token categories +``` + +### 6. Design System Principles + +#### Token Naming Convention +- Use kebab-case for CSS variables +- Group related tokens hierarchically +- Use semantic names over visual descriptions +- Include platform-specific variants when needed + +#### Component Design Principles +- **Consistency**: Use design tokens for all styling +- **Accessibility**: Implement proper ARIA and keyboard support +- **Responsive**: Design for all screen sizes +- **Performance**: Optimize for fast rendering +- **Maintainability**: Write clean, documented code + +### 7. Testing Strategy + +#### Component Testing +- Use Storybook for visual testing +- Test all variants and states +- Verify accessibility with screen readers +- Test responsive behavior +- Validate design token usage + +#### Token Testing +- Verify token generation works correctly +- Test token usage across components +- Validate CSS custom properties +- Check cross-platform compatibility + +### 8. Troubleshooting + +#### Common Issues + +**Tokens not updating in components** +- Run `npm run tokens` to regenerate +- Check import paths in CSS files +- Verify token file syntax + +**Storybook not loading** +- Check for TypeScript errors +- Verify component imports +- Restart Storybook server + +**Style conflicts** +- Use CSS modules to avoid conflicts +- Check CSS specificity +- Verify token variable names + +#### Getting Help +- Check the generated token files in `build/` +- Review Storybook documentation +- Test components in isolation +- Use browser dev tools to inspect styles diff --git a/src/UILayer/web/README.md b/src/UILayer/web/README.md new file mode 100644 index 0000000..9539a63 --- /dev/null +++ b/src/UILayer/web/README.md @@ -0,0 +1,123 @@ +# Cognitive Mesh UI + +A sophisticated, sci-fi inspired user interface built with Next.js, featuring advanced drag-and-drop functionality, real-time energy flow visualization, and a comprehensive design system. + +## Features + +- **Advanced Drag & Drop System**: Multi-handle drag styles with magnetic snap and gridlines +- **Real-time Energy Flow**: Dynamic particle system with configurable effects +- **Command Nexus**: AI-powered command interface with voice recognition +- **Design System**: Comprehensive token-based design system with Style Dictionary +- **Component Documentation**: Live Storybook documentation for all components +- **Responsive Layout**: Adaptive interface that works across all devices + +## Design System + +This project includes a comprehensive design system built with **Style Dictionary** that generates design tokens for multiple platforms: + +### Design Tokens +- **Colors**: Neural, synaptic, and cortical color palettes with semantic variants +- **Typography**: Inter, JetBrains Mono, and Orbitron font families with complete scale +- **Spacing**: Consistent spacing scale from xs to 6xl +- **Effects**: Gradients, shadows, and animations + +### Generated Outputs +- CSS Custom Properties (`build/css/_variables.css`) +- SCSS Variables (`build/scss/_cognitive-mesh-tokens.scss`) +- iOS/Android native formats +- Swift/Java code generation + +## Getting Started + +### Prerequisites +- Node.js 18+ +- npm or yarn + +### Installation +```bash +npm install +``` + +### Development +```bash +# Start the main application +npm run dev + +# Start Storybook (component documentation) +npm run storybook + +# Build design tokens +npm run tokens +``` + +### Available Scripts +- `npm run dev` - Start Next.js development server +- `npm run build` - Build for production +- `npm run start` - Start production server +- `npm run storybook` - Start Storybook documentation +- `npm run build-storybook` - Build static Storybook +- `npm run tokens` - Build design tokens with Style Dictionary + +## Project Structure + +``` +CognitiveMeshUI/ +├── src/ +│ ├── app/ # Next.js app directory +│ ├── components/ # React components +│ │ ├── CognitiveMeshButton/ # Design system component example +│ │ ├── Nexus/ # Unified nexus component +│ │ ├── DockZone/ # Dock area management +│ │ └── ... # Other components +│ ├── contexts/ # React contexts +│ └── hooks/ # Custom hooks +├── tokens/ # Style Dictionary token files +│ ├── colors.json # Color tokens +│ ├── typography.json # Typography tokens +│ └── spacing.json # Spacing tokens +├── build/ # Generated design tokens +│ ├── css/ # CSS custom properties +│ └── scss/ # SCSS variables +├── .storybook/ # Storybook configuration +└── style-dictionary.config.js # Style Dictionary config +``` + +## Design System Components + +### CognitiveMeshButton +A fully-featured button component that demonstrates the design system: + +- **Variants**: Primary, Secondary, Neutral, Semantic +- **Sizes**: Small, Medium, Large +- **States**: Default, Hover, Active, Disabled, Focus +- **Features**: Glow effects, smooth animations, accessibility support + +## Contributing + +1. **Design Tokens**: Add new tokens to the `tokens/` directory +2. **Components**: Create new components in `src/components/` +3. **Documentation**: Add Storybook stories for new components +4. **Build Tokens**: Run `npm run tokens` after token changes + +## Design System Integration + +### Using Design Tokens in Components +```css +/* Import generated tokens */ +@import '../../../build/css/_variables.css'; + +.my-component { + background: var(--color-cognitive-primary-neural); + font-family: var(--typography-font-family-primary); + padding: var(--spacing-md); +} +``` + +### Adding New Tokens +1.
