Phase 3 Exit Audit — Summary
Date: 2026-08-31
Gate milestone: 3.E.5 Phase 3 exit audit
Detailed register: docs/archive/032-phase3-exit-audit.md
Git SHA (main at audit): 45696a2
Verdict
Phase 3 is complete. Zero open P0 gaps. The composed memory substrate (schema → write pipeline → semantic search + composite ranking → hot cache) is validated by unit/integration tests, 12 ISO-* security cases, e2e lifecycle smoke, and three CI benchmark regression gates (HNSW, ranking-quality, write-pipeline).

What was already solid
- HNSW from greenfield schema (ADR-0052) — no IVFFlat migration
- Twelve ISO-* integration cases with real pgvector + Redis (
memory-security-integration) - Nine-step write pipeline including temporal conflict and multi-label
- Composite scoring v2 in search ranking and hot cache (ADR-0053, ADR-0059)
- Committed benchmark baselines with CI regression gates (ADR-0061)
- Per-memory FK cascade proven (ISO-2.1); org-scope GDPR explicitly deferred (ADR-0060)
- No proxy hot-path handler/middleware changes during Phase 3
Sign-off checklist
- Gap register complete (
032-phase3-exit-audit.md) - This summary published
- Zero open P0 gaps
- All 12 ISO-* cases pass (
pytest -m security_integration) -
memory-security-integrationrequired onmain - HNSW + ranking + write benchmark gates pass on
main -
e2e-smoke-p3-memoryrequired onci-gate-python - Corrected 10-item exit criteria verified
- CURRENT_STATE reflects Phase 3 complete
Next phase
Begin Phase 3.5: Extraction & Context Assembly — milestone 3.5.A.1 Celery worker skeleton.
