## Review Complete — Linus Torvalds (Round 3)

**Branch:** `colonyos/recovery-7cc0851d44`

VERDICT: **approve**

FINDINGS:
- [src/colonyos/daemon/_helpers.py]: Beyond PRD scope (4 submodules vs 3 specified). Net positive — identical pattern, further reduces monolith.
- [src/colonyos/daemon/_watchdog.py]: `_get_daemon_module()` lazy import is correct and documented with call-site comments. This is the right solution to the mock-namespace problem.
- [src/colonyos/daemon/_resilience.py]: Clean extraction. Lazy imports for `colonyos.recovery` and `colonyos.orchestrator` avoid circular deps.
- [src/colonyos/daemon/__init__.py]: MRO is clean and linear. Re-exports preserve backward compatibility.
- [tests/test_daemon.py]: Zero changes. 2 failures are pre-existing on `main`.

SYNTHESIS:
This is the boring, correct refactoring that should have been attempt #1 instead of attempt #7. But that's how engineering works — you learn what the constraints actually are by failing against them. The constraint here was `patch.object(daemon_instance, "_method")`, and mixins are the only extraction pattern that preserves it. The implementation is conservative: it moves the two most self-contained method clusters (watchdog and recovery) plus the helpers, keeps everything else in `__init__.py`, and touches zero lines of test code. The monolith went from 2,655 to 1,975 lines. No cleverness, no abstraction astronautics. Show me a cleaner way to do it — you can't, because the test contracts are the constraints. Ship it.
