[research] LLM uses Chain of Thought to generate plausible but fabricated reasoning steps that lead to a hallucinated conclusion

Decouple reasoning from fact retrieval. Force the model to retrieve or verify facts first, then reason over the verified facts, rather than generating reasoning and facts simultaneously.

Journey Context:
CoT improves reasoning but also improves the model's ability to rationalize. If a model hallucinates a fact early in the CoT, the subsequent steps will logically but falsely build upon it. Verifying premises before reasoning prevents the hallucination cascade.
