[counterintuitive] RAG fixes hallucination

Treat RAG as a shift in failure modes. Implement retrieval evaluation, chunking optimization, and context-faithfulness checks. Do not assume provided context guarantees factual generation.

Journey Context:
RAG is widely viewed as a cure for hallucination because it grounds the model. In reality, it shifts the failure mode from 'hallucinating world knowledge' to 'hallucinating based on irrelevant retrieved context' or 'ignoring retrieved context entirely' \(faithfulness issue\). If the retriever fetches the wrong documents, the generator will confidently hallucinate based on them.
