To audit FastAPI endpoint changes for Traefik forwardAuth security violations, validate that route modifications respect the Traefik-gated security model and do not inadvertently expose internal routes outside the established auth-path caches.

The correct FastAPI service lifecycle requires strict adherence to the critical startup and shutdown order alongside the app status machine, which prevents deadlocks and boot loops during signal-driven state synchronization.

Enforce architectural invariants when modifying Docker network topology and auth middleware by validating changes against established design constraints, ensuring Traefik-based auth enforcement and signal-driven invalidation rules remain uncompromised.

Yes, the shard_core architecture contract supports code reviews for signal-driven state synchronization protocols by applying strict compliance checks to design changes involving authentication and service lifecycle management.

Your app_factory.py modification likely breaks the existing auth-path cache by violating the Traefik forwardAuth design or bypassing the signal-driven invalidation rules that maintain architectural invariants and security constraints.
