+- Security annotations policy:
+  - Avoid inline `# nosec` comments unless strictly necessary (e.g., a vetted false positive that cannot be refactored away). Prefer:
+    - Parameterization and safe construction patterns (SQL placeholders, constant-only clause assembly).
+    - Tool configuration or non-strict runs locally (`make bandit`) and strict in CI (`make bandit-strict`) when needed.
+    - Tests that assert safety properties (e.g., correct SQL placeholders, timeouts applied) to prevent regression.
 - Follow-ups (optional):
   - Consider pinning reusable governance workflow to a stable tag/SHA for regulated environments.
   - Add real UI unit tests under `rdm-review-dashboard-ui/src/**/*.spec.ts` to enable meaningful UI CI coverage instead of skipping/empty-suite handling.
