Purpose of this document + +This document explains **how RAJEE uses immutable Quilt manifests to enforce authorization**, and what that design implies for: + +- the shape of **Cedar policies** stored in Amazon Verified Permissions (AVP) +- the shape of **RAJA authorization requests** +- the mental model admins should use when granting access + +This is an **admin- and architecture-facing** document, not an API reference. + +--- + +## 2. The core idea (in one paragraph) + +In Quilt, **authority is not defined by paths or file lists**. +Authority is defined by **immutable manifests**. + +Cedar determines *whether* a role may access a given manifest. +RAJA turns that decision into a **RAJ capability token**. +RAJEE enforces that capability by **unfolding the manifest** and allowing access *only* to the objects named by it. + +The manifest does **not grant authority**. +It **defines the boundary of authority**. + +--- + +## 3. Why immutable manifests matter + +Immutable manifests give Quilt a property most authorization systems lack: + +> A stable, content-defined identifier whose meaning never changes. + +This allows authorization to be expressed as: + +> “Role R may read Manifest M” + +without ever enumerating the files inside M in policy. + +Because manifests are immutable: + +- the authorized set cannot silently expand +- caching is safe +- tokens remain truthful for their lifetime +- enforcement does not rely on mutable storage structure (prefixes, folders) + +--- + +## 4. Two kinds of grants in Quilt + +Quilt supports **two distinct grant types**, because they solve different problems. + +### 4.1 Path grants (location-based) + +Path grants authorize access to: + +- a bucket +- an optional path (prefix or exact key) + +They are useful for: + +- infrastructure data +- shared prefixes +- operational workflows + +Path grants compile into Cedar policies over **S3Path resources** and explicit S3 actions. + +### 4.2 Manifest grants (content-based) + +Manifest grants authorize access to: + +- an **immutable manifest identifier** (as Quilt package with hash) + +They are useful for: + +- packages +- datasets +- any collection with thousands of files +- cross-bucket layouts + +Manifest grants compile into **one Cedar policy per grant**, regardless of file count. + +This document focuses on **manifest grants**. + +--- + +## 5. Cedar model for manifest grants + +### 5.1 Resource model + +Cedar treats each immutable manifest as a first-class resource: + +- Resource type: `Manifest` +- Resource ID: the immutable manifest identifier (hash or versioned ID) + +Cedar does **not** know or care about the files inside the manifest. + +### 5.2 Action model + +Cedar actions are **package-level**, not S3-level: + +- `quilt:ReadPackage` +- `quilt:WritePackage` + +This avoids leaking storage details into policy. + +### 5.3 Example Cedar policy + +```cedar +permit( + principal == Role::"analyst", + action == Action::"quilt:ReadPackage", + resource == Manifest::"pkg-abc@sha256:deadbeef" +); +``` + +This policy says exactly one thing: + +> The role `analyst` may read the package identified by this immutable manifest. + +It does **not** enumerate buckets, paths, or files. + +--- + +## 6. RAJA authorization requests for manifest grants + +### 6.1 What RAJA asks Cedar + +When a client requests access to a package, RAJA asks AVP: + +- principal: the role +- action: `quilt:ReadPackage` or `quilt:WritePackage` +- resource: the manifest ID +- optional context: time, client posture, etc. + +Cedar returns **ALLOW or DENY**. + +### 6.2 What goes into the RAJ (JWT) + +If allowed, RAJA mints a RAJ containing only **mechanically enforceable claims**: + +- `package_uri` (immutable) +- `mode` (read or readwrite) +- `exp` / `nbf` +- `aud` +- optional audit metadata + +The RAJ does **not** contain: + +- file lists +- prefixes +- buckets +- mutable references + +The RAJ is a **capability**: possession implies authority. + +--- + +## 7. How RAJEE enforces manifest grants + +RAJEE is the **enforcement point**. + +For each client request: + +1. RAJEE validates the RAJ: + - signature + - audience + - expiry + - action compatibility + +2. RAJEE resolves the manifest: + - using the immutable `package_uri` + - from a trusted, canonical location + - optionally from cache + +3. RAJEE enforces membership: + - requested `(bucket, key)` must be a member of the manifest + - no other objects are permitted + +4. RAJEE executes the S3 operation on behalf of the client. + +At no point does RAJEE: + +- consult Cedar again +- trust caller-supplied paths +- allow access outside the manifest boundary + +--- + +## 8. Why this does not introduce ambient authority + +This design remains **capability-based**, not ambient. + +- Authority originates in Cedar. +- Authority is made explicit in the RAJ. +- The manifest is used only as **evidence** to check membership. + +The client cannot: + +- choose the manifest +- modify the manifest +- expand the authorized set + +The manifest **constrains** authority; it does not create it. + +--- + +## 9. Implications for admins + +### 9.1 What admins grant + +Admins grant access to: + +- **packages (manifests)**, or +- **paths** + +They do not grant access to individual files. + +### 9.2 Why grants scale + +A single manifest grant can safely authorize: + +- thousands of files +- across multiple buckets +- without policy explosion + +Revocation is simple: + +- disable the grant +- let outstanding RAJs expire + +--- + +## 10. Design invariants (non-negotiable) + +- Manifests used for authorization are immutable. +- Cedar policies never enumerate files. +- RAJ scopes are explicit and minimal. +- RAJEE enforces exact membership. +- AVP is a decision engine, not a data catalog. + +--- + +## 11. Summary + +Manifest grants invert traditional authorization: + +- IAM authorizes **locations** +- Quilt authorizes **meaning** + +By anchoring authority to immutable manifests and enforcing it via RAJEE, Quilt achieves: + +- precision +- scale +- auditability +- and security properties that prefix-based IAM cannot provide. diff --git a/specs/4-manifest/01-package-grant.md b/specs/4-manifest/01-package-grant.md new file mode 100644 index 0000000..60ac077 --- /dev/null +++ b/specs/4-manifest/01-package-grant.md @@ -0,0 +1,840 @@ +# Package Grant Design: Package-Based Authorization + +## Executive Summary + +This document specifies the design for **package grants** - a content-based authorization model where authority is anchored to **immutable Quilt package packages** rather than mutable S3 paths. + +**Core Hypothesis:** + +> Authority should be defined by **what data means** (packages), not **where data lives** (paths). + +**Key Innovation:** + +Cedar policies reference immutable package identifiers.

for issuing package tokens - Add validate_package_token() for validating package tokens - Add enforce_package_grant() with membership checking callback - Add quilt_uri.py module for Quilt URI validation - Export new functions and models from raja package - Add comprehensive unit tests for package grant functionality Package grants enable authorization based on manifest membership: - Tokens contain quilt+s3:// URIs referencing specific packages - Membership checked via callback to external manifest resolver - Supports read and readwrite modes for S3 operations Co-Authored-By: Claude ---

AVP is the authoritative policy store and evaluator - there's no need to: 1. Fetch policies back from AVP 2. Parse Cedar with a local Python parser 3. "Compile" them to scopes The correct flow is: - scripts/load_policies.py expands templates and loads to AVP - AVP is the source of truth for policy evaluation - No compilation step needed Changes: - Removed POST /compile endpoint from control plane router - Removed scripts/invoke_compiler.py script - Removed compile-policies task from pyproject.toml - Updated deploy task to only run load-policies (not compile) - Fixed integration test to verify policies exist in AVP - Removed unit tests for the deleted compile endpoint Co-Authored-By: Claude --- pyproject.toml | 3 +- scripts/invoke_compiler.py | 83 ------------------ src/raja/server/routers/control_plane.py | 84 +----------------- tests/integration/test_control_plane.py | 8 +- tests/unit/test_control_plane_audit.py | 33 ------- tests/unit/test_control_plane_router.py | 107 ----------------------- 6 files changed, 7 insertions(+), 311 deletions(-) delete mode 100755 scripts/invoke_compiler.py diff --git a/pyproject.toml b/pyproject.toml index eec7183..15e099b 100644 --- a/pyproject.toml +++ b/pyproject.toml @@ -105,11 +105,10 @@ demo-package = { cmd = "pytest tests/integration/test_rajee_package_grant.py -v demo-translation = { cmd = "pytest tests/integration/test_rajee_translation_grant.py -v -s", help = "Run translation grant (TAJ-package) demonstrations" } # AWS deployment -deploy = { sequence = ["_npx-verify", "_cdk-deploy", "load-policies", "compile-policies"], help = "Deploy CDK stack to AWS, then load and compile policies" } +deploy = { sequence = ["_npx-verify", "_cdk-deploy", "load-policies"], help = "Deploy CDK stack to AWS and load policies to AVP" } deploy-fast = { shell = "IMAGE_TAG=$(bash scripts/build-envoy-image.sh --print-tag) && bash scripts/build-envoy-image.sh --tag \"$IMAGE_TAG\" --push && IMAGE_TAG=\"$IMAGE_TAG\" ./poe deploy", help = "Build/push Envoy image by content hash, then deploy with the pre-built image" } destroy = { sequence = ["_npx-verify", "_cdk-destroy"], help = "Destroy CDK stack" } load-policies = { cmd = "python scripts/load_policies.py", help = "Load Cedar policies to AVP" } -compile-policies = { cmd = "python scripts/invoke_compiler.py", help = "Compile policies to scopes" } seed-test-data = { cmd = "python scripts/seed_test_data.py", help = "Seed integration test principals into DynamoDB" } # Docker image building diff --git a/scripts/invoke_compiler.py b/scripts/invoke_compiler.py deleted file mode 100755 index 56779c5..0000000 --- a/scripts/invoke_compiler.py +++ /dev/null @@ -1,83 +0,0 @@ -#!/usr/bin/env python3 -"""Trigger the policy compiler Lambda function via API Gateway.""" - -from __future__ import annotations - -import os -import sys -import time -from pathlib import Path -import json -from urllib import request -from urllib.error import HTTPError, URLError - - -def main() -> None: - """Trigger policy compiler Lambda function.""" - api_url = os.environ.get("RAJA_API_URL") - if not api_url: - repo_root = Path(__file__).resolve().parents[1] - outputs_path = repo_root / "infra" / "cdk-outputs.json" - if outputs_path.is_file(): - try: - outputs = json.loads(outputs_path.read_text()) - api_url = outputs.get("RajaServicesStack", {}).get("ApiUrl") - except json.JSONDecodeError: - api_url = None - if not api_url: - print("✗ RAJA_API_URL environment variable is required", file=sys.stderr) - sys.exit(1) - - url = f"{api_url.rstrip('/')}/compile" - - print(f"{'='*60}") - print("Triggering policy compiler") - print(f"URL: {url}") - print(f"{'='*60}\n") - - print("→ Sending compile request...") - - start_time = time.time() - - try: - req = request.Request(url, method="POST") - with request.urlopen(req, timeout=30) as response: - if response.status != 200: - print(f"✗ Unexpected status code: {response.status}", file=sys.stderr) - sys.exit(1) - - body = response.read().decode("utf-8") - - elapsed = time.time() - start_time - - print(f"✓ Compilation completed in {elapsed:.2f}s\n") - print(f"{'='*60}") - print("Response:") - print(f"{'='*60}") - print(body) - - except HTTPError as e: - elapsed = time.time() - start_time - print(f"✗ HTTP error after {elapsed:.2f}s: {e.code} {e.reason}", file=sys.stderr) - try: - error_body = e.read().decode("utf-8") - print(f"\nResponse body:\n{error_body}", file=sys.stderr) - except Exception: - pass - sys.exit(1) - except URLError as e: - elapsed = time.time() - start_time - print(f"✗ Network error after {elapsed:.2f}s: {e.reason}", file=sys.stderr) - sys.exit(1) - except TimeoutError: - print("✗ Request timed out after 30s", file=sys.stderr) - print(" The compiler may still be running.
