## Review — Andrej Karpathy (Round 3)

**VERDICT: approve**

All 3 blockers from Round 2 are fully resolved, all 71 tests pass, and all 12 functional requirements are implemented. Here's my assessment:

### Previous blockers — now fixed
| Blocker | Status |
|---------|--------|
| FR-11 Slack kill switch missing | ✅ `_handle_control_command()` + `_register_daemon_commands()` with user auth |
| FR-6 Budget alerts not posted | ✅ 80%/100% threshold alerts via `_post_slack_message()` with once-per-day dedup |
| `WatchdogSec=120` without `sd_notify` | ✅ Removed from systemd unit |

### Non-blocking findings for V1.1
1. **CEO `run_ceo()` blocks main loop** — Called synchronously in `_tick()`, which means 10+ min LLM calls freeze heartbeats and polling. Not catastrophic (only runs when queue is empty), but should be threaded or enqueued.
2. **Starvation promotion has no ceiling** — Items crossing the 24h threshold get promoted every 5-second tick until they hit P0. Needs a `promoted_at` guard or min-priority floor.
3. **Daily digest unimplemented** — `digest_hour_utc` config exists but no trigger. Heartbeats partially cover this, but the "daily summary" user story is missing.
4. **Slack messages always P1** — Bug signal detection only checks labels, which Slack doesn't have. The "Slack bug → P0" path from the PRD doesn't work without manual intervention.
5. **Healthz fallback duplicates logic** — Standalone server re-implements `get_health()` computation.

### What's good
- **Atomic writes with fsync + rename** — The right crash-safety pattern, correctly implemented.
- **71 tests** covering budget, circuit breaker, kill switch auth, dedup, starvation, crash recovery.
- **Clean architecture** — Single process, sequential execution, `threading.Lock` for shared state, PID lock for single-instance.
- **`run_pipeline_for_queue_item`** bridges daemon→orchestrator cleanly with issue/prompt dispatch.

The remaining issues are quality improvements, not blockers. This daemon will do what the PRD promises. Ship it, then iterate.

FINDINGS:
- [src/colonyos/daemon.py L421-454]: CEO run_ceo() called synchronously blocks main loop for 10+ minutes during LLM call
- [src/colonyos/daemon.py L303-340]: Starvation promotion has no ceiling — items cross all tiers within seconds of hitting 24h
- [src/colonyos/daemon.py]: Daily digest trigger logic unimplemented (config exists)
- [src/colonyos/models.py L328]: Slack messages always P1 — bug signal detection only checks labels
- [src/colonyos/server.py L128-194]: Healthz fallback duplicates health computation logic

SYNTHESIS:
This is a well-executed V1 daemon. The architecture is right, the safety controls work, and the test coverage is thorough. All previous blockers are resolved. The remaining findings are V1.1 quality improvements that don't block shipping.
