Add pytest fixtures (engine, db_session, client) with session-scoped event loop to avoid asyncpg loop mismatch errors. Smoke tests verify all three main API endpoints return empty results on a clean DB. Test DB provided by docker-compose.test.yml on port 5433. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
