We introduce a geometric-topological field model where nucleons, leptons, and bosons emerge as curvature configurations of two intersecting base fields. The system alternates between symmetric (bosonic) and antisymmetric (fermionic) phases, generating four curved subfields that reproduce the charge, mass, and spin structure of known particles. All physical observables are derived from a single velocity ratio, r = c'/c = 0.931, calibrated from the proton-Higgs resonance. This single parameter yields:proton mass, magnetic moment, and effective charge radius as curvature scales;neutron, electron, and neutrino masses via internal decompression ratios;the fine-structure constant α as a geometric inclination (α = arctan(X/Y));Planck's constant as topological curvature action;quark radii from curvature-mass relations matching experimental mass hierarchies;W and Z boson masses as curvature inversions in the symmetric state.All computed values match experimental data within sub-percent precision. Mass, charge, and spin arise directly from curvature compression, decompression, and internal phase shifts, without perturbative QCD, Higgs couplings, or hidden parameters. A global 3π phase lag governs the internal resonance, connecting electromagnetic, weak, and strong forces under a unified geometric mechanism.
