[counterintuitive] RAG fixes hallucination

Implement robust retrieval evaluation, cross-encoder re-ranking, and citation verification. Treat RAG as shifting the failure mode, not eliminating it.

Journey Context:
Developers assume providing external documents via RAG stops the model from making things up. In reality, RAG shifts the failure mode from 'hallucination due to lack of knowledge' to 'hallucination due to misinterpretation of retrieved context' or 'retrieval failure'. If the retriever fetches irrelevant chunks, the LLM might still hallucinate, or worse, confidently force an answer based on a tangential retrieved chunk \(context-confabulation\). RAG requires rigorous chunking, embedding alignment, and evaluation of the retrieval step independently.
