Double-Slit Interference in a C-Parity Decomposition of the Dirac Field

We propose an interpretive note on the double-slit experiment within a charge-conjugation parity decomposition of the Dirac field. The C-even sectorplays the role of a global carrier of the excitation, while the experimental readout channel is mediated by local C-odd currents. We show that this algebraicseparation permits a relabeling of wave-particle duality without invoking a fundamental wavefunction collapse. The interference pattern is attributed to thestructure accessible to the C-odd readout channel, whereas the pointlike detection event is structurally located at the mixing channel between theC-even and C-odd sectors. The note introduces no new dynamics; it offers a structural clarification of the interface between global support and localreadout.
