[counterintuitive] RAG eliminates hallucination in LLMs

Implement robust retrieval evaluation and context-validation logic; RAG shifts the failure mode from parametric hallucination to misattribution or context ignorance.

Journey Context:
Developers assume providing external context forces the model to answer truthfully. In reality, models can still hallucinate \*within\* the provided context, ignore the context entirely and rely on parametric memory, or the retrieval system can fetch highly plausible but incorrect context, leading to 'faithful hallucinations' where the model confidently cites bad retrieved data. RAG trades one failure mode for another.
