# Decision Gate

Verdict: **GO**

---

## Decision Gate Result

```
VERDICT: GO
```

### Rationale
All 5 personas unanimously approve with no CRITICAL or HIGH findings remaining. The implementation satisfies all 10 functional requirements from the PRD: config defaults flipped to sequential, a new `_run_sequential_implement` function processes tasks one-at-a-time in topological order with git commits between each, failed tasks correctly block dependents while independent tasks continue, and parallel mode remains fully functional as an opt-in. The 922-line test suite (32 tests) provides thorough coverage.

### Unresolved Issues
None blocking.

### Recommendation
Merge as-is. The decision artifact has been written to `cOS_reviews/decisions/20260329_235500_decision_when_we_implement_a_new_functionality_from_the_tasks_it_should_not_happen_in_par.md`.
