[counterintuitive] RAG fixes hallucination

Implement strict citation verification and retrieval evaluation; treat RAG as a context-shifting mechanism, not a hallucination cure.

Journey Context:
It is widely believed that providing external documents via RAG stops models from making things up. In reality, RAG shifts the failure mode from 'fabricated facts' to 'fabricated relevance' or 'ignored context'. Models often hallucinate that the retrieved text supports an answer it doesn't, or they override the provided context with their pre-trained weights if a conflict arises. RAG without forced citation and grounding constraints often yields confidently hallucinated connections to real documents.
