[counterintuitive] Does RAG eliminate LLM hallucinations

Implement robust retrieval validation \(e.g., claim extraction, citation verification, or context-adherence scoring\) and do not assume retrieved context guarantees factual generation.

Journey Context:
The belief is that providing external documents anchors the model to facts. In reality, LLMs still suffer from faithfulness errors where they ignore the retrieved context, mix it with parametric memory, or misinterpret it. RAG shifts the problem from 'hallucinating from scratch' to 'hallucinating from misaligned context.' Without explicit enforcement, RAG can actually increase hallucination by giving the model conflicting information that it tries to reconcile.
