[counterintuitive] RAG eliminates LLM hallucinations

Treat RAG as a risk reducer, not an eliminator: audit retrieval quality, require verbatim citations or quotes, allow the model to say "I don't know," and verify high-stakes answers independently.

Journey Context:
RAG shifts the failure mode from parametric hallucination to retrieval failure: stale chunks, semantic mismatches, bad chunk boundaries, or missing context can all produce confident but wrong answers. The model may also ignore retrieved text or invent citations. Reliability comes from the retrieval layer \(chunking, hybrid search, reranking\) plus generation constraints \(quotations, source restriction, fallback refusals\).
