"""Live end-to-end tests for AIPEA.

These tests exercise real AIPEA components with real inputs and real outputs.
Zero use of unittest.mock, patch, MagicMock, or AsyncMock for internal components.
Only monkeypatch.setenv() for environment variable isolation.

Tests verify OUTPUT QUALITY — not just types and structure, but whether the
pipeline produces semantically correct, well-formed results.

Run: pytest tests/test_live.py -v
Or:  make live
