[counterintuitive] Adding RAG eliminates hallucination

Implement robust citation verification and self-correction loops. RAG merely shifts the generation prior; you must explicitly instruct the model to only use the provided context and verify its output against the retrieved chunks.

Journey Context:
The belief is that giving the model the 'right answer' in the prompt means it will just repeat it. But LLMs are pattern completers. If the retrieved context is contradictory, sparse, or dense, the model will still confabulate to resolve it. RAG reduces but does not eliminate hallucination; it just gives the model something to ignore or misinterpret.
