Pauli-Limit Magnetic Coupling and Tree-Level Magnetic Moment of an Electron-Like Packet in the ECSM Framework
Year: 2026
Type: preprint
Abstract: This paper presents the V24 stage of the ECSM electron-like packet programme. Building on the V21b near-electron rest-energy scale, the V22 coherent-limit Dirac-like propagation result, and the V23 emergent gauge-coupling doorway, V24 tests whether the same inherited packet supports the Pauli-limit magnetic coupling structure and tree-level magnetic moment relation. The notebook recovers the Pauli spin-field splitting, the tree-level g = 2 magnetic moment doorway, the nonrelativistic Dirac-to-Pauli kinetic limit, and spin precession under a uniform effective magnetic response field. The final V24 verdict is PASS_STRONG. The result does not claim the anomalous magnetic moment, Schwinger correction, Lamb shift, scattering amplitudes, radiative corrections, or full QED. It establishes a narrower necessary layer: the ECSM electron-like packet now supports Pauli-limit magnetic coupling and tree-level g = 2 structure on top of the previously recovered packet scale, Dirac-like propagation, and minimal gauge coupling.
