"""Phase 3-5 tests for entity matching (mock by default; live with RUN_LIVE=1).

    docker compose exec bot python tools/test_matching.py            # mock only

The live section calls DeepSeek (NLU) and TypeSafe (Jev) with the REAL keys
from bot/.env — it never sends anything to Bale and never creates drafts.
