[counterintuitive] RAG fixes hallucination by grounding the model in retrieved facts

Treat RAG as a context provision mechanism, not a hallucination cure; implement citation verification and faithfulness-checking pipelines, as models will still hallucinate by contradicting the provided context.

Journey Context:
The belief is that if you give the model the right document, it won't make things up. In reality, models still hallucinate within a RAG setup. They might ignore the retrieved context entirely and rely on parametric memory, or they might 'hallucinate' by stitching together disparate facts from multiple chunks incorrectly. Furthermore, if the retrieval fails and fetches irrelevant documents, the model will often hallucinate an answer that fits the irrelevant context rather than saying 'I don't know.'
