+## Optional LLM Extraction
+
+The `llm_extraction` module is designed to work with the sibling `llm-connect`
+project without making it a hard dependency. To enable provider-backed
+extraction locally:
+
+```bash
+python -m pip install -e ../llm-connect
+```

+`execute_prompt(prompt, config)` and parses strict JSON candidate drafts from
+model responses. Tests use a fake adapter, so the default test suite does not
+call external providers.
