[counterintuitive] RAG fixes hallucination

Implement strict retrieval relevance thresholds and post-generation citation verification. Treat RAG as a context-shaping tool, not a hallucination cure, and validate that the generated output strictly aligns with the retrieved chunks.

Journey Context:
The consensus is that providing external documents forces the model to ground its answers, eliminating hallucinations. The reality is that RAG shifts the failure mode from 'hallucination' to 'misinformation propagation' or 'context confusion'. If the retrieved context is irrelevant, the model may still hallucinate by blending the useless context with its pre-trained weights. If the context is contradictory, the model may pick the wrong side or invent a synthesis. RAG without enforcement actually increases the risk of highly confident, context-induced hallucinations.
