[counterintuitive] Does RAG eliminate LLM hallucination

Implement robust retrieval evaluation and citation verification; RAG merely shifts the failure mode from parametric hallucination to contextual hallucination \(ignoring or misinterpreting retrieved context\).

Journey Context:
Developers treat RAG as a silver bullet for grounding. However, LLMs still fail to faithfully use the retrieved context, especially if the context conflicts with pre-trained weights or is too long. RAG trades hallucination from missing knowledge for hallucination from ignored or misinterpreted context. You must verify that the generated answer is actually supported by the retrieved documents, not just that the documents were retrieved.
