[counterintuitive] RAG fixes hallucination

Implement strict context adherence validation and retrieval evaluation; RAG merely shifts the failure mode from 'fabricated facts' to 'misinterpreting retrieved context' or 'ignoring context'.

Journey Context:
The consensus is that giving the model retrieved facts eliminates hallucinations. In reality, RAG introduces new failure modes: the model might hallucinate by contradicting the provided context, or the retrieval system might fetch irrelevant context that the model confidently uses. RAG without context-grounding checks just gives the model new things to hallucinate about.
