[counterintuitive] Does RAG eliminate LLM hallucinations

Implement robust retrieval evaluation, citation enforcement, and fallback mechanisms. Treat RAG as context grounding, not a hallucination cure.

Journey Context:
The belief is that giving the model the right data stops it from making things up. In reality, RAG introduces new failure modes: retrieval failures \(wrong chunk retrieved\), context ignoring \(model relies on pre-trained knowledge over the context\), and confabulation on the retrieved text. If the model doesn't know how to use the context, or the context is conflicting, hallucination persists or worsens.
