Context

get_db_client() in auth.py instantiates a new DatabaseClient on every call. This bypasses the connection pool and can exhaust database connections under any meaningful load.

What to do

  • Identify where the application-level DatabaseClient / connection pool is initialized (likely in database.py or the FastAPI lifespan).
  • Refactor auth.py to receive the shared client via FastAPI dependency injection (Depends(get_db)) rather than constructing its own.
  • Ensure all auth route handlers use the injected client.
  • Remove the standalone get_db_client() helper from auth.py if it is no longer needed.

Acceptance criteria

  • Only one DatabaseClient instance is created per application lifecycle.
  • Auth routes continue to function correctly after the refactor.
  • No regressions in existing tests.

Roadmap reference: P1 Error handling — get_db_client() bypasses connection pool.
