# V2-P7A Closeout Checklist

Status: Complete
Related: `docs/v2_p7a_kickoff.md`

## Goal
Confirm authority-completion outcomes for P7A.

## Step progress
- [x] Step 1 of 5 — session-write authority foundation
- [x] Step 2 of 5 — engine-first orchestration ownership expansion
- [x] Step 3 of 5 — session-authority propagation into key read/write paths
- [x] Step 4 of 5 — index projection demotion hardening
- [x] Step 5 of 5 — full sweep + closeout

## Acceptance criteria
- [x] session-first semantics materially present in write-time and query-time authority paths
- [x] memory engine owns more integration orchestration behavior
- [x] catalog relation sourcing remains canonical-association-first
- [x] index is explicitly framed and maintained as projection cache
- [x] no contract drift in memory execute/search/reason

## Validation evidence

### Full regression
- Command: `python -m unittest discover -s tests -p 'test_*.py'`
- Result: **186 passed / 0 failed**

### Eval snapshots
- `memory_execute_eval`: stable vs prior phase
- `paraphrase_eval`: stable vs prior phase

## Outcome
P7A is complete. The most critical critique gap (session-first authority vs index-first tension) is materially reduced through concrete authority-path changes and projection-cache demotion semantics.

## Next phase
Proceed to P7B for deeper semantic/store completion and remaining architectural closure.
