Taste Rating: 🟡 Acceptable (with critical fixes needed)

Verdict: ❌ Needs rework - Tests not updated, incomplete change

Key Insight: Consistency fix is good taste, but you broke the tests.

---

The model naming change from gpt-5-3-codex to gpt-5.3-codex makes sense for consistency with other models (e.g., gpt-5.2-codex), but this PR is incomplete.
