# Review by Linus Torvalds (Round 3)

VERDICT: approve

FINDINGS:
- [src/colonyos/orchestrator.py]: `_save_run_log` mutates `log.preflight.head_sha` as side effect of save — minor coupling concern, acceptable for V1
- [src/colonyos/orchestrator.py]: Dirty file list truncated at 10 entries — good UX decision for repos with many uncommitted files
- [src/colonyos/cli.py]: `_ensure_on_main()` correctly treats pull failure as warning, checkout failure as fatal — right priority ordering
- [tests/test_preflight.py]: 607 lines of tests for ~220 lines of implementation — appropriate coverage ratio for safety-critical code

SYNTHESIS:
This is a clean, well-structured implementation that does exactly what the PRD asks for and nothing more. The code is procedural where it should be procedural — no LLM calls, no over-engineered abstractions. The fail-closed semantics on git status errors are correct (if you can't determine state, refuse to proceed). The separation between state-gathering helpers and decision logic makes the code testable and the tests comprehensive. The `PreflightError` subclass is a good design — it lets autonomous mode catch preflight failures specifically without swallowing unrelated exceptions. All 10 functional requirements are implemented, all 275 tests pass (including 44 dedicated preflight tests), no TODOs remain in shipped code, and no secrets or destructive operations are present. The only nit is the head_sha mutation in `_save_run_log`, but that's a minor coupling issue, not a correctness bug. Ship it.
