  "context": "This project has NO AI policy — no AI_POLICY.md, no AI mention in CODE_OF_CONDUCT.md. The agent should correctly identify 'no policy' (not 'banned'), recommend voluntary disclosure, follow CONTRIBUTING.md, use the hidden test helper fixtures from conftest.py, update the changelog, and read .cursorrules even though it's a Cursor-specific file. Rejected PR #7 shows the consequence of ignoring test patterns.",
