Self-Reflective RAG with LangGraph — Post-Retrieval Validation Loop.
Story
Add a grading node after retrieval: score chunks for relevance, rewrite the query and re-retrieve if below threshold, then apply a hallucination grader on generation output. Two loops: retrieval quality and generation faithfulness. Implementation uses LangGraph conditional edges: retrieve → grade → (generate | rewrite → retrieve). LangChain Blog
