[counterintuitive] RAG fixes hallucination

Implement robust citation verification and self-correction loops; RAG only shifts the prior, it does not enforce truth. Place critical retrieved context at the beginning or end of the prompt.

Journey Context:
Developers assume providing external documents forces the model to use them exclusively. In reality, models suffer from 'attention distraction' or 'lost in the middle', where they ignore retrieved docs and fall back to parametric memory, or hallucinate connections between disjoint retrieved chunks. RAG is a retrieval mechanism, not a truth-enforcement mechanism. If the model's weights strongly disagree with the context, the model may still override the context.
