[counterintuitive] Does Retrieval-Augmented Generation \(RAG\) eliminate hallucination

Implement robust citation verification and self-correction loops; treat RAG as a context-shifting mechanism, not a hallucination cure.

Journey Context:
Devs assume injecting ground-truth context anchors the model to facts, eliminating made-up answers. In reality, RAG only changes the \*source\* of hallucination. Models still hallucinate by misattributing info in the context, failing to synthesize multiple chunks, or confidently repeating a retrieved but incorrect document. RAG shifts the failure mode from 'I don't know but I'll guess' to 'The context says X, so I'll confidently output X even if X is wrong', which is often harder to detect.
