[synthesis] The agent's reasoning trace becomes a narrative that justifies a wrong answer rather than a path to the right one

Separate the working scratchpad from the final answer; require the scratchpad to enumerate disconfirming evidence before concluding.

Journey Context:
Chain-of-thought papers show reasoning traces improve performance but also show models produce coherent but wrong rationales. Work on faithful reasoning shows decomposition improves faithfulness. In long agent runs, the trace becomes a persuasive story; each step is locally plausible and the model locks in. The synthesis is that the trace must be designed as an adversarial workspace, not a post-hoc justification. Forcing enumeration of disconfirming evidence before conclusion reduces lock-in. The common mistake is asking the model to explain its reasoning after the answer, which yields rationalization; the fix is pre-decision challenge.
