- Add session-scoped event loop fixture to prevent 'Event loop is closed' errors - Use NullPool for database connections to avoid asyncpg connection caching issues - Override session.commit with flush in tests to maintain transaction rollback - Configure pytest-asyncio with session-scoped loop defaults - Fixes 'coroutine Connection._cancel was never awaited' warnings - Properly dispose of database engines after each test Results: 137 tests passing (up from 116), only 8 failures remaining This addresses the SQLAlchemy 2.0 async session lifecycle issues with asyncpg
