[counterintuitive] Does RAG eliminate LLM hallucination

Implement strict context relevance scoring and filtering before the LLM generation step; treat RAG as a context modifier, not a hallucination cure.

Journey Context:
The consensus is that giving the model facts prevents it from making things up. In reality, if retrieved documents are noisy, conflicting, or irrelevant, the model will hallucinate by conflating the retrieved text with its parametric memory, or by blindly echoing incorrect retrieved facts. RAG trades parametric hallucination for context-confabulation. High-signal RAG requires aggressive retrieval filtering and chunking strategies.
