Implementation:
1. Apply the smallest safe change first.
2. Keep each change narrow and testable.
3. Preserve existing working behaviour.
4. Add or recommend test scenarios.

Final output:
- Problem summary.
- Root cause or best diagnosis.
- Changes applied or recommended.
- Files, routes, tables, functions, or integrations affected.
- Risk level.
- Test checklist.
