[counterintuitive] RAG fixes hallucination

Implement robust chunking, re-ranking, and source validation; treat RAG as context grounding, not a hallucination cure.

Journey Context:
It is widely believed that providing documents via RAG stops models from making things up. In reality, RAG often changes the nature of hallucinations rather than eliminating them. If the retrieved context is irrelevant, the model may hallucinate by forcing a connection between the query and the unrelated text. If the context is conflicting, the model might synthesize a false answer from contradictory fragments. Furthermore, models suffer from the 'lost in the middle' effect, ignoring retrieved context if it is buried in a long prompt, falling back on parametric memory and hallucinating anyway.
