[counterintuitive] Does RAG eliminate hallucination

Implement output validation and faithfulness checks; RAG reduces but does not eliminate hallucination and can introduce context-conflicting errors.

Journey Context:
Developers assume providing context via RAG forces the model to use only that context. In reality, models suffer from context adherence failure where they revert to parametric memory if the retrieved context conflicts with their training data, or they hallucinate by combining retrieved facts incorrectly.
