[counterintuitive] Does RAG eliminate LLM hallucinations

Implement robust retrieval evaluation, chunking strategies, and citation verification. Treat RAG as context-injection, not a hallucination cure.

Journey Context:
The belief is that giving the model the right answer in the prompt will stop it from making things up. In reality, RAG introduces new failure modes: the model can ignore the retrieved context, contradict the context, or the retrieval system can fetch irrelevant/misleading chunks that the model then hallucinates around. RAG shifts the problem from 'model doesn't know' to 'model can't synthesize or verify retrieved context'.
