[synthesis] Confidence Escalation From Orthogonal Successes Causes Skipped Verification on Remaining Steps

Track success criteria independently per step or per subtask. Partial success on criterion A must not increase confidence for criterion B. Use a per-item checklist that resets confidence to neutral for each new item.

Journey Context:
An agent successfully configures 3 of 5 API endpoints. Its confidence rises. For the remaining 2, it skips reading the docs \(because the first 3 were straightforward\) and assumes the same pattern applies. But endpoints 4 and 5 require different authentication. The agent's elevated confidence causes it to skip verification, leading to auth failures it then misdiagnoses as network issues \(because 'the auth pattern works—I just used it'\). The compounding loop: confidence → less verification → wrong diagnosis → wrong fix → more confidence in the wrong direction. This is the agent version of the 'hot hand fallacy.' The fix—per-item confidence reset—feels unnatural because humans and agents both reason by analogy. But analogy is exactly the failure mode when the remaining items differ from the completed ones. The tradeoff is that resetting confidence makes the agent slower and more cautious, but this is precisely what prevents the confidence-escalation death spiral.
