[synthesis] Agent doubles down on incorrect assumption for 3\+ consecutive steps despite contradictory tool results

Implement a 'belief challenge' protocol where the agent must explicitly generate a counter-argument to its previous conclusion before proceeding to the next step; if tool results contradict the working hypothesis, trigger a hard reset of reasoning chain

Journey Context:
LLMs exhibit strong self-consistency bias—they weight their previous outputs heavily when generating next tokens. In multi-step agent workflows, this creates a cascade where an early error becomes 'ground truth' for subsequent reasoning. Standard retry logic fails because the model simply re-generates the same erroneous reasoning path. The belief challenge protocol forces the model to break its own consistency loop by requiring explicit consideration of alternatives. This interrupts the autoregressive entrenchment before it can compound across multiple steps.
