[counterintuitive] RAG fixes hallucination

Implement robust chunking, re-ranking, and source attribution validation, and explicitly instruct the model to say 'I don't know' if the context is insufficient. RAG shifts the failure mode from 'hallucination from parametric memory' to 'hallucination from misretrieved/ignored context'.

Journey Context:
Developers assume giving the model the right text means it will use it. In reality, models suffer from 'lost in the middle' \(fail to attend to middle context\), they can still override retrieved context with their parametric memory, or they might misinterpret the retrieved text. RAG without strict grounding just gives the model new things to hallucinate about.
