[counterintuitive] Does RAG eliminate LLM hallucination

Treat RAG as context augmentation, not a hallucination cure. Implement retrieval scoring, citation enforcement, and explicit 'unanswerable' routing, because LLMs will still hallucinate by blending retrieved context with parametric memory or ignoring context entirely.

Journey Context:
The belief is that giving the model the right facts prevents it from making up facts. In reality, LLMs suffer from attention dilution. If the retrieved context conflicts with strong parametric memory, the model often trusts its pre-trained weights. Furthermore, irrelevant retrieval actively increases hallucination by giving the model more raw material to confabulate with.
