[counterintuitive] Adding RAG \(Retrieval-Augmented Generation\) eliminates hallucinations

Implement robust retrieval evaluation and citation verification; RAG shifts the failure mode from 'hallucination' to 'misinformation retrieval' or 'context ignorance'.

Journey Context:
RAG is often treated as a silver bullet for factual accuracy. In reality, if the retriever fetches irrelevant, conflicting, or outdated documents, the LLM will confidently hallucinate based on the wrong context. Worse, LLMs can suffer from 'context ignorance', ignoring the provided context entirely and hallucinating from pre-training data. RAG without retrieval quality control often increases hallucination rates because the model feels compelled to use the injected context even if it is wrong.
