**Round 2 result: 4/4 approve (unanimous)**

## Findings Summary

### Round 1 blocking issues (all resolved in Round 2)
- ❌→✅ Failing test (`test_all_commands_in_readme`) — README updated
- ❌→✅ Dead code path in stats (`compute_delivery_outcomes` never called) — wired into `compute_stats`
- ❌→✅ FR-3.2 missing (`run_thread_fix` not tracked) — `_register_pr_outcome` added
- ❌→✅ No UNIQUE constraint on `pr_number` — added `UNIQUE` + `INSERT OR IGNORE`
- ❌→✅ No SQLite timeout — added `timeout=10`
- ❌→✅ Unrelated TUI scrollbar fix — reverted
- ❌→✅ `_extract_ci_passed` treating in-progress checks as failures — fixed
- ❌→✅ Inconsistent imports in orchestrator — cleaned up
- ❌→✅ Redundant DB connections in `format_outcome_summary` — consolidated

### Remaining findings (all LOW / non-blocking)
- Duplicated stats computation (~20 lines) between `compute_outcome_stats` and `format_outcome_summary`
- `review_count` calculation repeated 3 times in `poll_outcomes`
- Unnecessary `ImportError` guard in `stats.py`
- No pruning strategy for `pr_outcomes` table (acknowledged as open question in PRD §8)
- `poll_outcomes` holds SQLite connection during sequential `gh` subprocess calls
- CEO prompt placement should be monitored for model signal usage

VERDICT: GO
```

### Rationale
All four personas unanimously approve in Round 2. Every CRITICAL and HIGH finding from Round 1 — failing test suite, dead code path in stats integration, missing FR-3.2, and the UNIQUE constraint data integrity issue — has been fully addressed. The implementation covers all 8 functional requirement groups from the PRD with 37 new tests and zero regressions across the full 2380-test suite. The remaining findings are LOW-severity code quality nits (duplicated computation, missing pruning strategy) that don't affect correctness, security, or functionality.

### Unresolved Issues

(None blocking. The following are V2 follow-ups:)
- Extract shared stats computation helper to eliminate duplication between `compute_outcome_stats` and `format_outcome_summary`
- Add pruning strategy for `pr_outcomes` table (PRD Open Question #1)
- Monitor whether the CEO agent actually uses outcome signal to change behavior
- Consider batch-fetching GitHub data before DB updates in `poll_outcomes` if open PR count grows

### Recommendation
Merge as-is. The implementation is complete, tested, secure, and follows all existing project conventions. The remaining findings are minor code quality improvements suitable for a follow-up cleanup pass, not blockers for shipping.
