## Findings Summary

### CRITICAL
None.

### HIGH
None.

### MEDIUM (non-blocking, noted for follow-up)
1. **Orchestrator re-indentation diff** — The `_run_pipeline()` try/finally wrapper creates a ~360-line indentation-only diff, making review harder and increasing merge conflict risk. All four reviewers flagged this. Functionally correct; cosmetic concern.
2. **Global FIFO pruning vs per-category FIFO** — Deviates from PRD spec. Documented in code comments with clear rationale. Acceptable at 500-entry cap; per-category quotas noted as v2.
3. **Naive keyword extraction** — First 8 words ≥3 chars from prompt text, no stopword filtering. Retrieval quality will degrade as store grows. Recency fallback is a sound safety net. v2 improvement path is clear.

### LOW
4. Unrelated TUI style changes bundled in branch (Linus flagged).
5. `load_memory_for_injection` docstring says prompt_text is "reserved for future" but it's actively used.
6. `_get_memory_store` catches bare `Exception` — could mask SQLite corruption (Security flagged as acceptable).
7. `memory delete` lacks confirmation prompt unlike `memory clear`.
8. FTS5 query uses exact phrase match — individual OR terms would improve recall.
9. Token estimation via chars÷4 systematically undercounts for code-heavy memories.

VERDICT: GO
```

### Rationale
All four personas unanimously approve after three review rounds. No CRITICAL or HIGH findings remain. The implementation covers all six PRD functional requirements (storage layer, capture hooks, prompt injection, config, CLI commands, learnings coexistence) with 78 dedicated tests, zero new dependencies, and strong security properties — parameterized SQL, FTS5 sanitization, content sanitization via `sanitize_ci_logs()`, and orchestrator-only writes preventing agent memory poisoning. The documented deviations (global vs per-category FIFO, stricter sanitization function) are defensible engineering trade-offs for an MVP.

### Unresolved Issues
- Orchestrator `_run_pipeline()` re-indentation creates large diff and split resource ownership — refactor in follow-up.
- Keyword extraction needs stopword filtering and per-term OR matching for better retrieval quality (v2).
- Unrelated TUI style changes should ideally be split to a separate commit.
- Per-category FIFO pruning quotas deferred to v2.

### Recommendation
**Merge as-is.** The memory system is functionally complete, well-tested, and security-hardened. The identified issues are all non-blocking improvements that can be addressed incrementally. File follow-up tickets for: (1) orchestrator resource ownership cleanup, (2) retrieval quality improvements (stopword filtering, OR-based FTS queries), and (3) per-category pruning quotas.
