We derive baryonic antimatter from the UD field equations, extending the leptonic antimatter mechanism to composite systems. The proton is shown to be the minimal baryon, containing two entity Dd cores and one entity Dᵤ excitation. This structure is established by a variational minimization of the static field energy for competing (Dd, Dᵤ) configurations, which selects the 2Dd+1Dᵤ state as the lightest hadronic bound state, and is independently confirmed by the neutron decay n p+e^-+ₑ derived in the companion QCD paper. The two entity Dd cores generate an effective third Dd field via field coupling, while the single retained Dᵤ inherits the original three-color basis and satisfies the color singlet constraint through its continuous color field distribution. The universal phase-flip rule + applies to the single Dᵤ component, converting the proton into an antiproton. Proton-antiproton annihilation proceeds via Dᵤ phase cancellation, forcing both entity Dd cores to dissolve into Ud with energy release E ₀₍₍=2mₚ c²1. 88~GeV. The antiproton decay rate from quantum tunneling is the single-channel WKB rate. All derivations are self-contained, with the effective field generation and color transformation properties rigorously proved in the Appendices.
