This paper develops a USP Field Theory interpretation of antimatter as a phase-inverted and boundary-reconnected resonance topology. The purpose is not to replace the Standard Model description of antiparticles, QED, QCD, CPT symmetry, or established antimatter experiments. Instead, the document supplies a resonance-geometry interpretation layer for matter–antimatter symmetry, boundary incompatibility, and annihilation. In this framework, matter and antimatter are treated as opposite stable closure orientations of the same resonance architecture. Their internal energy density and resonance frequencies are preserved, while their accessible boundary-coupling orientation is reversed. Text-form summary: Matter topology = TUSP, RH Antimatter topology = TUSP, LH Internal energy preserved: uₐntimatter (r) = uₘatter (r) omegaₐntimatter = omegaₘatter Boundary orientation reversed: Cₐntimatter = -Cₘatter For composite hadrons and nuclei, the paper emphasizes that antimatter inversion is not a single spin flip or simple wavefunction sign change. Instead, it requires coordinated rearrangement of multi-node corridor connectivity and accessible boundary orientation. Annihilation is interpreted as boundary incompatibility. When matter and antimatter surface corridors overlap within a finite corridor-locking width, stationary confinement fails and stored energy redistributes into propagating modes such as photons, pions, leptons, and other hadronic products depending on the channel. Text-form annihilation-access condition: etaₐnn = |Delta fₛurf (matter) + Delta fₛurf (antimatter) | / Gammaₐnn <= 1 The paper also connects the antimatter interpretation to earlier USP concepts: stationary oscillations, coherent locking, neutron surface cancellation, hadronic knot collapse, and Delta-f elasticity. It includes operational quantities, falsifiable directions, and safe public wording.
