[counterintuitive] RAG fixes hallucination

Implement retrieval evaluation, citation verification, and answer-grounding checks. Treat RAG as a context-shifting technique, not a hallucination cure.

Journey Context:
RAG is widely believed to eliminate hallucinations by grounding the model in factual context. In reality, RAG shifts the failure mode: instead of hallucinating from pre-training data, the model can ignore the retrieved context \(context ignorance\), hallucinate by blending the prompt with the retrieved text, or confidently regurgitate retrieved misinformation. RAG actually introduces new attack surfaces via retrieval poisoning and increases the cognitive load on the attention mechanism, leading to 'lost in the middle' failures.
