[counterintuitive] Does RAG eliminate LLM hallucinations

Implement robust retrieval evaluation, citation verification, and chunking strategies; treat RAG as context-grounding, not a hallucination cure, as models can still ignore context or hallucinate based on retrieved noise.

Journey Context:
The widespread belief is that giving the model the right facts stops it from making things up. In reality, models suffer from 'attention dilution' or 'lost in the middle' where they ignore retrieved context, or they hallucinate connections between disparate retrieved chunks. RAG shifts the failure mode from 'fabricating facts from pre-trained weights' to 'misinterpreting or ignoring retrieved context', which can be harder to debug.
