[synthesis] Agent generates increasingly confident explanations for wrong answers, making rollback psychologically impossible for the model

Decouple confidence assessment from explanation generation. Use separate scoring that compares output against objective criteria or known baselines, not self-assessed confidence after generating explanatory text.

Journey Context:
As agents generate explanations for their actions, each generated token reinforces the narrative. By the time an agent has written 500 words explaining why X is correct, its probability of outputting 'actually, X might be wrong' approaches zero—not because the evidence changed, but because the generated text creates a local coherence gradient. This is distinct from the self-validation echo chamber: it is about how the act of generating supporting text itself increases perceived confidence regardless of correctness. The model's confidence score after explanation is meaningless because it measures consistency with the explanation, not correctness of the answer. Objective scoring against external criteria is the only reliable confidence signal.
