[synthesis] Agent's confidence increases after each step even when early steps silently failed — compounding errors feel like progress

Implement explicit confidence calibration checkpoints: at each major step, the agent must list what it assumes to be true and what evidence supports each assumption. If any assumption lacks positive evidence \(not just absence of error\), confidence should decrease. Track a failure budget — if N steps pass without external validation, force a validation checkpoint before continuing.

Journey Context:
This is the most dangerous compounding pattern. An agent completes step 1 \(silently failed\), step 2 \(built on wrong state from step 1 but no error thrown\), step 3 \(further from correct but working\). At each step the agent's internal confidence increases because it is making progress — generating code, modifying files, running commands. The absence of explicit errors is interpreted as success. By step 7 the agent is highly confident in a completely wrong state. This is the agent equivalent of the Dunning-Kruger effect: the agent does not know what it does not know, and each step that does not crash feels like confirmation. The fix is not just check for errors — it is actively seeking disconfirming evidence. The failure budget is the key mechanism: if you have gone 5 steps without an external ground truth check \(test pass, human review, diff approval, runtime verification\), something is probably wrong. The budget number depends on task risk but the principle is universal: unvalidated progress is not progress, it is unvalidated drift.
