[counterintuitive] RAG fixes hallucination

Treat RAG as a context-shaping tool, not a hallucination cure. Implement robust retrieval evaluation, chunking strategies, and citation verification, as RAG can cause \*more\* targeted hallucinations if the retrieved context is irrelevant or conflicting.

Journey Context:
Developers assume giving the model the 'right answer' in the prompt stops it from making things up. In reality, LLMs suffer from 'attention dilution' or 'context confusion' when presented with multiple retrieved chunks. If the top-k chunks are irrelevant, the model is forced to use its weights anyway, or worse, it stitches together a plausible-sounding answer from conflicting retrieved documents \(e.g., conflicting financial reports\). RAG shifts the failure mode from 'hallucination from no data' to 'hallucination from conflicting/noisy data'.
