UnverifiedTwinCheck is a verification strategy that runs at inference time and verifies whether to replace the agent's proposed action by constructing counterfactual candidate actions (negative twins) bound to the current trajectory.76% similarUnverifiedSince this fix touches cache consistency logic, after upgrading one should focus on validating cache hit rates and inference correctness.72% similarUnverifiedTwinCheck replaces the agent's original proposal only when the negative twin simultaneously passes the structural check and the pairwise verifier prefers it under both candidate orderings.70% similarUnverifiedThe standard method for controlling position bias is 'symmetric evaluation': evaluating two answers twice with their positions swapped, and treating the result as a valid judgment only when both evaluations reach the same conclusion69% similar
