Gauge Interfaces in a C-Parity Framework: An Interpretative Note

In previous foundational work, we formulated a charge-conjugation (C) parity decomposition of the Dirac field, where the C-even sector functions as the globally supported mass-energy carrier and local C-odd currents provide the operational readout channel. This interpretative note extends this framework toward a structural interpretation of gauge interactions. We postulate that the C-even carrier acts as a macroscopically stable primitive above the Compton scale. Within this setting, the Standard Model gauge groups are not treated as arbitrary additions to the matter ontology, but are interpreted as operational interface symmetries: $U(1)$ as the conserved phase-readout interface, $SU(2)_L$ as the chiral transition interface, and $SU(3)$ as the native internal antisymmetry interface required by fermionic statistics in three-component local probes. This note does not derive the Standard Model gauge dynamics or any quantitative phenomenological prediction, nor does it reject the Standard Model Lagrangian as an empirically validated effective interaction calculus. It proposes instead a conceptual and structural reclassification of its gauge sectors within the C-parity bi-particle framework.
