[counterintuitive] RAG fixes hallucination

Implement robust chunking, re-ranking, and source attribution validation. RAG shifts the failure mode from 'hallucination due to lack of knowledge' to 'hallucination due to misretrieval, conflicting context, or lost-in-the-middle attention'.

Journey Context:
Developers think giving the model the right text means it will just read it. But models suffer from 'lost in the middle' where they ignore relevant middle context, or they exhibit sycophancy where they ignore the context if it contradicts their pre-training and the user's prompt implies a different answer. RAG can actually increase hallucination if the retrieved context is noisy or contradictory.
