[counterintuitive] RAG fixes hallucination

Implement strict context-adherence validation and citation checking; treat RAG as a probability-shifting constraint, not a guarantee of factual grounding.

Journey Context:
RAG is widely believed to eliminate hallucinations by anchoring the model to retrieved documents. In reality, models still suffer from 'contextual hallucination'—ignoring the provided context, blending it with outdated parametric memory, or fabricating facts not supported by the exact text. RAG narrows the output distribution but does not strictly bind the model to the context window.
