Conversation
Implements the cognitive memory API as designed in
docs/unified-cognitive-memory-architecture.md:
Foundation tier (Refs & Derivations):
- GET/PUT/DELETE /refs/{ref_name:path} with optimistic locking
- GET /refs/{ref_name:path}/history - version history
- GET /refs - list refs with prefix filter
- GET /passages/{id}/sources - derivation sources
- GET /passages/{id}/derived - derived passages
Cognitive tier (Frames & Cognition):
- POST /frames - create cognitive frame
- GET /frames/{name} - get frame
- GET /frames - list frames
- POST /frames/{name}/fork - fork frame
- POST /frames/{name}/activate - activate frame
- POST /frames/{name}/resolve - resolve to frozen snapshot
- POST /cognition/increment - atomic state transitions
New files:
- schemas.py: Pydantic models for all API endpoints
- cognitive_router.py: FastAPI router for cognitive endpoints
- frames.py: Frame service implementation
- cognition.py: Cognition increment service with optimistic locking
E2E test coverage:
- Scenarios A-T from the design document
- HTTP API tests for all new endpoints
- 16 tests passing against testcontainers Postgres
