[counterintuitive] RAG fixes hallucination

Implement retrieval evaluation and context-grounding metrics \(like faithfulness scoring\), and use structured output validation; do not assume RAG eliminates hallucinations.

Journey Context:
RAG is widely treated as a cure for hallucination. In reality, RAG merely shifts the failure mode from 'fabricating facts from pretraining' to 'fabricating facts from the provided context' \(context hallucination\) or 'ignoring the provided context' \(context ignorance\). The generative model still retains its propensity to hallucinate, especially if the retrieved context is ambiguous, conflicting, or overwhelming.
