## Review Summary

**VERDICT: approve**

This is a well-executed implementation. The core architectural decision — procedural logic over an LLM agent phase — is exactly right. Git state assessment is deterministic and closed-form; burning tokens on it would be wasteful. A `PreflightResult` dataclass gives you auditability without polluting cost tracking.

### Key Strengths

1. **Clean separation of concerns**: State gathering (subprocess calls) is isolated from decision logic (raise or proceed), making everything unit-testable without real repos.
2. **Correct fail-closed/fail-open asymmetry**: Dirty working tree → hard refuse. Fetch timeout → warn and proceed. This is exactly the right calibration of failure modes.
3. **Actionable error messages**: Every refusal tells the user exactly what to do ("commit or stash", "use --resume", "use --force"). Treating CLI output as program output for humans.
4. **Auto mode resilience**: Pre-flight `ClickException` is caught, iteration marked failed, loop continues. No halting on recoverable state.
5. **528 lines of tests** covering all edge cases — clean repo, dirty tree, existing branch ± PR, offline mode, force mode, fetch timeout, resume SHA divergence.

### One Minor Nit

- **`tests/test_preflight.py:267`**: Typo `AssertionError` (missing `s`) instead of `AssertionError`. Non-blocking since that code path is only hit on test regression, but would produce a confusing `NameError` instead of a clean assertion failure.

All 10 functional requirements from the PRD are implemented. All tests pass (258 total). No secrets, no unnecessary dependencies, no unrelated changes. Ship it.
