+Implementation note
+- Status: checklist authored and reviewed (May 30, 2026).
+- Scope: keys, CORS, logging hygiene, and operational controls — actionable repo-specific items.
+- Next steps: implement high-priority items in `backend/` (API key persistence, CORS tightening, logging sanitizer), then run tests and open a PR.
