[counterintuitive] Does RAG eliminate LLM hallucinations

Implement citation verification and chunk overlap strategies. Treat RAG as a context-shifter, not a hallucination cure, and validate that the generated answer is strictly grounded in the retrieved context.

Journey Context:
The consensus is that providing external documents via RAG stops models from making things up. In reality, RAG shifts the failure mode from parametric hallucination to context-grounded confabulation. Models can ignore retrieved context, blend it with internal parametric memory, or fabricate bridges between disparate chunks. Furthermore, models suffer from 'lost in the middle', ignoring relevant documents placed in the center of the context window. RAG mitigates but does not eliminate hallucination.
