[counterintuitive] RAG eliminates LLM hallucination

Implement answer-grounding validation \(e.g., citation extraction or entailment classifiers\) alongside RAG; treat RAG as context provision, not a hallucination cure.

Journey Context:
The belief is that if the model has the right context, it won't hallucinate. In reality, RAG shifts the failure mode from 'hallucinating from parametric memory' to 'hallucinating from the provided context' \(e.g., making incorrect inferences, blending retrieved chunks, or ignoring the context entirely\). Models still suffer from attention dilution and will confidently output ungrounded statements even with perfect context.
