## Review Complete — Andrej Karpathy

**VERDICT: approve** ✅

### Key Findings

1. **All 8 functional requirements met.** `daemon.py` → `daemon/` package with 4 submodules. `__init__.py` reduced from 2,655 to 1,975 lines (beating the ~2,100 target). Zero changes to tests or CLI.

2. **152/155 tests pass.** The 3 failures (`TestDailyThreadLifecycle` rotation tests) are pre-existing on `main` — confirmed by running the same tests on the main branch.

3. **The `_get_daemon_module()` pattern is the star of this PR.** The watchdog mixin lazily imports `colonyos.daemon` at call time so that `patch("colonyos.daemon.request_active_phase_cancel")` substitutions take effect. This treats the test mock namespace as a contract — exactly right.

4. **`_HelpersMixin` is beyond PRD scope** (PRD specified 3 submodules, implementation has 4), but follows the identical pattern and the task file planned for it. Acceptable scope expansion.

5. **5 clean sequential commits**, each independently revertable. This is the approach that should have been used on attempts 1-6.

6. **No circular imports, no new dependencies, no secrets, no commented-out code.** Clean.
