Report #103310

[synthesis] Agent repeatedly confirmed its own wrong assumption because each verification step reused the same flawed premise

Separate verification from execution: the verifier must be given only the raw observations and the original goal, not the executor's intermediate conclusion. Use independent tool calls or a second pass over source artifacts, and require the verifier to quote evidence before agreeing.

Journey Context:
The temptation is to let the agent 'check its work' by asking itself 'is this correct?' That simply reruns the same latent bias. Real adversarial validation means constraining the input to the verifier so it cannot see the hypothesis it is evaluating. This is costly because it duplicates work, but it is the only way to break confirmation bias. A lighter-weight compromise is to force the model to produce evidence citations in a structured format before any conclusion.
