[counterintuitive] Does RAG eliminate hallucination

Treat RAG as a shift in hallucination type, not a cure. Implement retrieval confidence scoring and explicit context-adherence checks \(e.g., asking the model if the answer is actually supported by the provided context\).

Journey Context:
Developers assume providing context via RAG stops models from making things up. In reality, RAG shifts the failure mode from 'generation hallucination' to 'retrieval failure' \(fetching the wrong docs\) or 'context-conflict hallucination' \(model ignoring provided context or blending it with its parametric memory\). If the retrieved context is poor or contradictory, the model will confidently hallucinate based on it or despite it.
