[counterintuitive] RAG fixes hallucination

Implement robust retrieval evaluation and chunking strategies; RAG merely shifts the failure mode from 'model invents facts' to 'model misinterprets retrieved context' or 'retriever fetches wrong context'.

Journey Context:
Devs think providing context forces the model to be factual. In reality, if the retriever returns irrelevant or contradictory chunks, the model will happily hallucinate based on that, or ignore the context and rely on its pre-trained weights. RAG trades parametric hallucination for contextual hallucination. The model's attention mechanisms can still fail to synthesize the provided context accurately.
