Readout-Gramian Kinematics of Optical Phase Singularities: Jacobian Collapse, Fold Annihilation, and Apparent Superluminal Defect Motion

This paper introduces a readout-Gramian framework to demonstrate that the apparent superluminal motion of optical phase singularities is a geometric artifact of chart failure caused by the collapse of the Fisher-information metric (Jacobian) near fold annihilation events, rather than a violation of physical signal velocity limits.
