[counterintuitive] Does RAG eliminate LLM hallucinations

Implement robust retrieval evaluation, citation verification, and context-adherence scoring. Treat RAG as a shift in hallucination failure modes, not a cure.

Journey Context:
Developers assume injecting ground-truth context forces the model to abandon hallucinations. In reality, RAG shifts the failure mode from 'hallucination from parametric memory' to 'contextual hallucination'—where the model ignores the provided context, misinterprets it, or makes false inferences bridging two retrieved chunks. If the model's pre-trained weights strongly contradict the retrieved context, the model will often override the context. RAG requires explicit instruction-tuning for reading comprehension and strict adherence.
