# Decision Gate

Verdict: **GO**

```
VERDICT: GO
```

### Rationale

All four persona reviewers unanimously approved in their final round (Round 3): Andrej Karpathy, Linus Torvalds, Principal Systems Engineer, and Staff Security Engineer. All 10 functional requirements from the PRD are fully implemented. The implementation correctly uses procedural logic (not LLM calls) for deterministic git state checks, has fail-closed semantics on the critical path (`git status` and `git checkout` failures raise errors rather than silently proceeding), and includes 607 lines of dedicated test coverage across 44 test cases. Earlier rounds raised CRITICAL findings (fail-open on `git status` OSError, missing HEAD SHA validation for resume), and these were all resolved before the final round.

### Unresolved Issues

- `_ensure_on_main()` runs `git pull --ff-only` even when `--offline` is set (MEDIUM)
- `_get_head_sha` returns empty string on failure, making resume tamper-detection silently skip (MEDIUM)
- `_save_run_log` mutates `log.preflight.head_sha` as a side effect (LOW)
- `--force` flag lacks an explicit audit warning to stderr (LOW)
- Task 7.3 manual happy-path test unchecked (process gap)

### Recommendation

Merge as-is. The two MEDIUM items should be tracked as fast-follow issues but do not block shipping — the blast radius of both is limited since the critical-path checks (dirty working tree, branch existence) are fail-closed. The implementation achieves all five PRD goals.
