From UV Saturation to Quantum Matter in ECSM

This paper consolidates and corrects the ECSM matter-emergence chain from ultraviolet response saturation to stable localisation, triadic closure, charge-like composition, collective spinor orientation, and emergent exclusion. The work resolves earlier ambiguities concerning the closure mode, distinguishes triadic composition from two-state spin orientation, corrects the U(2) to SU(2) reduction, and separates exchange antisymmetry from finite-response occupancy cost. The paper presents a coherent theoretical scaffold and a falsifiable numerical programme. It does not claim a complete derivation of the Standard Model.
