[research] LLM states a hallucinated fact first, then rationalizes it in the Chain-of-Thought

Enforce 'Think step-by-step before answering' strictly, and ideally use a two-pass generation: first generate the reasoning, then generate the answer conditioned only on the reasoning.

Journey Context:
Standard CoT often suffers from 'post-hoc rationalization.' The model samples an answer token early due to high probability, and then constructs a plausible-sounding reasoning path to justify that predetermined \(and potentially wrong\) answer. Separating reasoning generation from answer generation mitigates this bias.
