## API Documentation

### Phase 7 APIs
- **[T7_VERSIONING_API.md](api/T7_VERSIONING_API.md)** — Version history, diffs, point-in-time queries
  - GET /memory/entities/{id}/versions
  - GET /memory/entities/{id}/diff?from=v1&to=v2
  - GET /memory/entities/{id}/at?as_of=timestamp

- **[T7_RANKING_API.md](api/T7_RANKING_API.md)** — Multi-signal ranking (7 signals, 3 profiles)
  - GET /memory/ranking/profiles
  - POST /memory/query with ranking_profile

- **[T7_REBUILD_API.md](api/T7_REBUILD_API.md)** — Deterministic rebuild with checksums
