[counterintuitive] RAG fixes hallucination

Implement retrieval evaluation, chunking strategies, and citation verification. Treat RAG as a shift in failure mode from 'fabrication' to 'misattribution', requiring output grounding checks.

Journey Context:
Developers assume providing context forces the model to use it exclusively. In reality, LLMs can still hallucinate within the provided context, or confidently state things contradicting the context \(context ignorance\). RAG does not fix hallucination; it merely changes the failure mode from making things up from pre-training data to making things up about the provided context, or ignoring the context entirely when it conflicts with pre-trained weights.
