 ⚠️ **Test Database Configuration**: CI and production both use PostgreSQL (via `DATABASE_URL` in `.github/workflows/ci.yml`). If you run tests locally with SQLite or another database, be aware of potential behavior differences and ensure migrations and tests are validated against PostgreSQL before merging. See [action items](../_bmad-output/implementation-artifacts/action-items-2026-02-02.md) for details.

+✅ **Frontend Tests**: Frontend CI is now fully implemented with comprehensive quality checks.
