Context

get_db_client() in auth.py creates a new DatabaseClient on every call, bypassing the connection pool. Under load this will exhaust available database connections.

Roadmap reference: ROADMAP.md > P1 > Error handling and resilience

What to do

  • Identify how the main application manages its DatabaseClient (likely via FastAPI dependency injection or a module-level singleton)
  • Refactor auth.py to reuse the same pooled client rather than constructing a new one per request
  • Ensure the shared client is properly initialized at startup and cleaned up on shutdown
  • Verify existing auth routes still function correctly

Acceptance criteria

  • get_db_client() (or its replacement) returns a shared, pooled client
  • No new DatabaseClient instance is constructed per request in auth routes
  • Database connections do not leak under repeated auth requests
  • All existing tests pass

Resolved (triage review): auth.py uses a module-level _db_client singleton with init_db_client()/close_db_client()/get_db_client(). No new DatabaseClient is created per request. Closing as already complete.
