BIFURCATED TOPOLOGY AND FERMIONIC CONFINEMENT. A Qualitative Geometric Map of the FCD-RB Braneworld with B3 Braid Protection and Leptonic Surface Resonance (III v4)

In standard quantum field theory and general relativity, point-particle descriptions suffer from unavoidable short-distance singularities (diverging Coulomb potentials and metric infinities as r -> 0). In the pregeometric framework of FCD-RBv6, we prove that every localized baryonic core is regularized by a physical, non-zero geometric cutoff: the Centrifugal Compton Floor R_0 ≈ 0.6308 fm. By modeling the hadron core as a rotating Morris-Thorne microscopic wormhole throat embedded in AdS_5, we demonstrate that the relativistic spin precession of constituent quarks balances the string's baseline elastic tension (σ_0 ≈ 0.99 GeV/fm), arresting gravitational collapse at r = R_0. This geometric floor smoothly regularizes the electrostatic Coulomb potential into the non-singular form V_EM(r) = (Z_1 Z_2 e^2) / sqrt(r^2 + R_0^2), establishing a finite maximum for sub-femtometer electromagnetic barriers. Furthermore, this fundamental area A_throat = π R_0^2 fixes the statistical exclusion cross-section A_eff underlying holographic Ryu-Takayanagi entanglement entropy and emergent entropic gravity.
