[counterintuitive] Adding RAG eliminates hallucination

Treat RAG as a context-shifting mechanism, not a hallucination cure. Implement citation verification and relevance scoring, as RAG can cause 'context-confabulation' where the model forces an answer from irrelevant retrieved chunks.

Journey Context:
Developers assume giving the model the 'right answer' in context means it will just parrot it. In reality, models often hallucinate more confidently when given partial or irrelevant context via RAG, trying to bridge the gap between the prompt and the retrieved text. RAG shifts the failure mode from 'making things up from pre-training' to 'misinterpreting or forcing connections from retrieved context'. An agent must verify the retrieved context actually supports the generated claim.
