# Review by Andrej Karpathy (Round 2)

## Review Complete — Andrej Karpathy, Round 6

**VERDICT: approve** ✅

All **15 functional requirements** verified and implemented. **56/56 tests pass.** All 6 task groups marked complete. All findings from previous review rounds (rounds 1–5) have been addressed.

### What's Right

The core design decision is correct: PR sync is a **deterministic git operation** — no model calls, no AI budget burn. The module is a pure function of (config, DB state, subprocess) with no stochastic components. The fail-closed design (`_STALE_STATES` whitelist) means unknown GitHub API values are safely ignored. The 1-PR-per-tick sequential model keeps blast radius small. Worktree isolation via `WorktreeManager.create_detached_worktree()` prevents working tree corruption. The escalation path (conflict → Slack + PR comment → max failures → suspension) is well-structured.

### 4 Non-Blocking Findings (V1.1)

1. **[daemon.py]**: FR-13 write gate reads only `dashboard_write_enabled` config, not `COLONYOS_WRITE_ENABLED` env var — works in practice but inconsistent with spec
2. **[test_pr_sync.py]**: `subprocess.run` patched globally instead of at module level — fragile mock target
3. **[outcomes.py]**: `get_sync_candidates()` uses `SELECT *` — consider narrowing to needed fields
4. **[pr_sync.py]** *(approving note)*: `_STALE_STATES` whitelist is the correct fail-closed pattern for unknown API values

### SYNTHESIS

This ships the smallest correct thing. The architecture leaves a clean seam for V2 AI conflict resolution — conflict file lists are already captured, and `Phase.CONFLICT_RESOLVE` is ready to slot in. The test-to-code ratio (~2:1) covers every gate condition. Approve.
