tatlock/tests/e2e/test_orchestration_e2e.py

"""
End-to-end tests for orchestration scenarios.

Tests the full stack including:
- Memory storage and recall via REST API
- Qdrant data verification
- Multi-expert coordination
- Direct delegation bypass

These tests hit the actual running server and verify data persistence.
They use the `llm_tester` user for isolation from production data.

Requirements:
- Server running on localhost:8777 (use `make run`)
- Qdrant running on localhost:6333
- Ollama running with the gemma4:e2b model

Note: LLM outputs are non-deterministic. Tests use flexible assertions
that check for behavioral patterns rather than exact text matches.
