[counterintuitive] RAG fixes hallucination

Implement answer-grounding verification \(e.g., citation checks or an LLM-as-a-judge step\) post-generation. RAG shifts the failure mode from parametric hallucination to contextual hallucination.

Journey Context:
Developers assume injecting retrieved context forces the model to tell the truth, eliminating hallucinations. In reality, LLMs often ignore retrieved context if it conflicts with strong parametric weights, or they hallucinate that the context says something it doesn't. RAG increases citation availability but does not guarantee groundedness. The model can still confidently output a false claim and attribute it to the provided context.
