# Decision Gate

Verdict: **GO**

**VERDICT: GO** ✅

The decision artifact has been written to `cOS_reviews/decisions/20260401_132000_decision_you_are_a_code_assistant_working_on_behalf_of_the_engineering_team_the_following.md`.

**Summary:**
- **4/4 personas approved** unanimously across both review rounds
- **Zero CRITICAL or HIGH findings**
- The fix is minimal and precisely targeted: 12 lines in `learn.md` + 25 lines of regression tests
- All PRD functional requirements (FR-1 through FR-5) are satisfied
- No changes to enforcement code, allowed_tools, budget, or downstream consumers

**Recommendation:** Merge as-is. File a follow-up ticket for extending tool-constraint declarations to other phase templates.
