# V2-P2 Closeout Checklist

Status: Complete
Related: `docs/v2_p2_kickoff.md`, `docs/v2_p2_trigger_map.md`, `docs/v2_p2_enforcement_test_matrix.md`

## Goal
Confirm P2 completion: canonical in-process trigger authority for per-turn and flush paths, with sidecar downgraded to legacy compatibility.

## Step progress
- [x] Step 1 of 5 — canonical trigger orchestrator introduced (turn-finalized path)
- [x] Step 2 of 5 — finalize/flush entrypoints routed to canonical executor (+ admin CLI fail-safe)
- [x] Step 3 of 5 — sidecar marked legacy compatibility with authority markers
- [x] Step 4 of 5 — P2 enforcement matrix tests implemented
- [x] Step 5 of 5 — full regression/eval sweep and closeout gate

## P2 acceptance criteria
- [x] documented per-turn trigger hooks are enforced in canonical in-process path
- [x] flush hook uses canonical transaction/orchestration path
- [x] manual admin flush trigger exists and follows canonical semantics
- [x] sidecar is compatibility path, not authority source
- [x] idempotency and no-dual-authority behavior validated by tests

## Validation evidence

### Full regression
- Command: `python -m unittest discover -s tests -p 'test_*.py'`
- Result: **152 passed / 0 failed**

### Eval summary (memory_execute)
- count: 50
- ok_rate: 1.0
- non_empty_results_rate: 1.0
- confidence_high_rate: 0.88
- answerable_rate: 1.0
- causal_grounding_achieved_rate: 1.0
- causal_strong_grounding_rate: 0.8421
- surface_alignment_rate: 1.0
- durable_query_archive_hit_rate: 0.88
- ungrounded_causal_surface_mismatch_rate: 0.0

### Eval summary (paraphrase)
- paraphrase_consistency_at_5: 0.085
- paraphrase_consistency_at_10: 0.17
- anchor_hit_rate: 0.85
- intent_match_rate: 0.7
- non_causal_why_rate: 0.0

## Outcome
V2-P2 is closed. Canonical trigger authority is now established in-process for mainline paths, with compatibility behavior preserved as legacy sidecar path.

## Next phase
Proceed to V2-P3 (transactional flush implementation hardening):
- enforce enrichment barrier strictly
- stage-level replay safety under induced failures
- checkpoint-driven resume semantics
