[counterintuitive] Does RAG eliminate LLM hallucinations

Implement robust retrieval evaluation, context grounding checks, and citation enforcement; treat RAG as a shift in failure modes, not a silver bullet for hallucination.

Journey Context:
Developers assume providing retrieved context forces the model to use it, eliminating made-up answers. In reality, models still suffer from 'context ignorance' where they override provided context with strong parametric weights, or they hallucinate by combining retrieved chunks in logically invalid ways. RAG simply shifts the failure mode from 'hallucination from parametric memory' to 'hallucination from ignored/contradictory retrieved context' or 'retrieval failure'.
