[counterintuitive] RAG eliminates hallucination

Implement RAG with robust retrieval validation \(e.g., self-consistency checks, citation verification\) and fallback mechanisms. Treat RAG as context grounding, not a hallucination cure.

Journey Context:
The belief is that if the model has the right document, it won't make things up. In reality, models still hallucinate within the context—combining contradictory facts from two retrieved chunks, or ignoring the context entirely if the prompt strongly implies a different answer. The 'lost in the middle' phenomenon also means retrieved context might be ignored. RAG shifts the failure mode from 'fabricating from pre-training' to 'fabricating from provided context'.
