  abstract = {This article develops the Zero Torque Counterfactual
    (ZTCF) family and Zero Velocity Counterfactual (ZVCF) as
    model-conditioned diagnostic tools. By simulating virtual
    trajectories under zero torque or zero velocity interventions, it
    attributes forward-dynamics outcomes to drift versus control
    actuation without biological overclaims.}
