[counterintuitive] Does Retrieval-Augmented Generation RAG eliminate hallucination

Implement robust citation verification, retrieval relevance scoring, and explicit 'I don't know' instructions. Treat RAG as context grounding, not a hallucination cure.

Journey Context:
The belief is that giving the model the right documents stops it from making things up. However, models still hallucinate within the retrieved context \(e.g., combining disparate facts incorrectly\) or confidently override the context with parametric memory if the context contradicts its pre-trained weights. RAG shifts the failure mode from completely fabricated facts to misinterpreted or ignored retrieved context.
