[synthesis] Confidence anchoring causing exponential error compounding in multi-step reasoning

Implement 'epistemic checkpointing'—force the agent to re-evaluate the certainty of previous conclusions at specific intervals \(every N steps or at tool boundaries\) using a distinct 'verification' prompt that doesn't share the reasoning chain of the original steps

Journey Context:
Standard chain-of-thought assumes errors are independent or linear, but in practice, once step 1 is slightly wrong, step 2 doesn't just add its own error—it multiplies the previous error because it uses the wrong conclusion as a premise. This is 'error cascades' in formal logic. Simply asking the agent to 'be careful' doesn't work because the model doesn't have access to its own confidence calibration across the reasoning chain. The fix requires architectural separation: a second instance or prompt that verifies without the 'momentum' of the original reasoning path.
