[counterintuitive] Does Retrieval-Augmented Generation eliminate hallucination

Implement answer-grounding verification \(e.g., citation checking, prompting the model to state 'I don't know' if context is insufficient\) because RAG merely shifts the failure mode from 'hallucination from lack of knowledge' to 'hallucination from misinterpreting retrieved context'.

Journey Context:
The belief is that giving the model the right documents means it will just read them. In practice, models often ignore retrieved context if it conflicts with pre-trained weights, or they hallucinate connections between disjoint retrieved chunks. RAG changes the type of hallucination rather than eliminating it entirely.
