CHARGE WITHOUT CHARGE: THE TRANS-BRANE MASS-ASYMMETRY RULE AND NUCLEON STRUCTURE (XIV v6)

In the FCD-RBv6 pregeometric framework, electric charge, light quark flavor, and nucleon composition are derived from a single topological entity: the trans-brane Einstein–Rosen (ER) dipole regularized at the Compton floor R₀ ≈ 0.6308 fm. The Standard Model treats electric charge as an intrinsic scalar property, quark flavor as an arbitrary representation choice, and lepton number as an independent conserved charge. Here we resolve these ad hoc assumptions through five unified topological principles: (1) The Single-Quark Dipole Hypothesis, where up and down quarks are not distinct fundamental particles but the two stable elastic ground states (Mode A and Mode B) of a single ER dipole of total construction budget M = 3m; (2) The Formal Distinction between the Construction Energy Ledger (M = 3m) injected non-radiatively via Mouth C to extrude the throat and the Observable Confined Mass (~938 MeV) sustained by relativistic gyroscopic rotation (7.6 × 10²² Hz) at the Compton floor; (3) The Trans-Brane Mass-Asymmetry Rule (TBMAR), coupled to the global orientation parameter Ω = ±1 (Q_visible = Ω · Q_TBMAR), deriving exact fractional charges (+2/3e, -1/3e) and integer nucleon charges without intrinsic scalar charge; (4) The Mirror-Nucleon Correspondence, proving that the proton (AAB) mirrors to an antineutron (BBA) and the neutron (ABB) mirrors to an antiproton (BAA), establishing an electromagnetically silent mirror dark sector; and (5) The Primordial Mass Imbalance (M_mir / M_vis ≈ 1.155 for p/n ≈ 7:1), representing the bare anchor asymmetry that, when coupled to the 50:50 bulk tension partition (2m_L + 2m_H), yields the cosmic dark-to-baryonic ratio Ω_DM / Ω_BM = 5.32. All gravitational couplings are governed by isotropic statistical depletion of AdS₅ microstates (dS = 0).
