[research] LLM generates a plausible but factually flawed Chain-of-Thought \(CoT\) to justify a hallucinated answer

Decouple reasoning from retrieval; force the model to cite specific, verifiable evidence for every claim in the CoT, and validate the entailment between the citation and the claim using an NLI model.

Journey Context:
CoT improves reasoning but also increases the surface area for hallucination. Models will reverse-engineer a plausible-sounding logical path to justify a hallucinated conclusion \(post-hoc rationalization\). A CoT is only as factual as its premises. Enforcing strict citation-to-claim entailment using Natural Language Inference verifiers catches fabricated premises in reasoning steps before they propagate to the final answer.
