[counterintuitive] Does RAG eliminate LLM hallucinations

Treat RAG as a context expansion mechanism that shifts the \*type\* of hallucination from factually ungrounded to contextually conflated; implement strong chunk isolation and citation verification.

Journey Context:
RAG provides facts, but it also provides distractors. Models suffer from 'lost in the middle' attention dilution, leading them to hallucinate by combining attributes from different retrieved chunks. RAG often \*increases\* hallucination when the retrieved context is contradictory or noisy, as the model attempts to reconcile conflicting inputs rather than rejecting them.
