Report #101739

[synthesis] Agent is confidently wrong for several consecutive steps because each step assumes the previous output is correct

Insert pause-and-validate checkpoints after every non-trivial intermediate result; verify with an external oracle \(test, diff, search, or deterministic check\) before the next step can use it. Do not ask the same model to self-correct without new evidence.

Journey Context:
Chain-of-thought improves interpretability but not correctness calibration; models are often more fluent than accurate. When an agent builds a file edit plan, a wrong premise in step 2 becomes an axiom for steps 3-6. Asking the model 'are you sure?' rarely works because it re-generates a justification from the same contaminated context. External oracles break the chain by introducing ground truth that the model cannot rationalize away.
