[research] Model's stated reasoning does not match its actual decision process, hiding hallucinated steps

Require chain-of-thought to cite the exact source or context line that justifies each step; audit by intervening on the cited evidence and checking whether the conclusion changes predictably.

Journey Context:
Lanham et al. and Turpin et al. show CoT can be unfaithful: models produce plausible post-hoc rationales that don't determine the answer. For coding agents, this means a 'because' explanation may be confabulated. Faithfulness improves when reasoning steps are tied to verifiable premises and when answers change predictably when premises are altered.
