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

Abstract

The pregeometric framework FCD-RB (Folded Crunch Dip ole – Reversed Big Bang) reinterprets 4D spacetime as an emergent holographic pro jection of a bifurcated 5D bulk, in which two parallel 3branes are separated by a Planck-scale interval (d ⇠l` P). Within this picture, fermions are modeled as extended trans-brane dipolar defects (Einstein – Rosen bridges), while gauge bosons emerge as localized vibrational modes of the inter-brane substrate. In this v4 revision, we uni fi cate the sub-hadronic and leptonic sectors by tracing the conceptual evolution of the electron. We detail how the early model ’ s conjecture of the electron as an independent, trivial free strand (B 1 ) was discarded due to ontological fragmentation, and resolve it by establishing the electron as a lo calized leptonic surface resonance (Rayleigh wave) of the minority-mass endpoint of the quark ER dipole itself (specifi cally the Mode A / Up quark visible endpoint with mass m = M / 3). Furthermore, we formalize baryonic confi nement and the absolute stability of the proton as top ological invariants of the non-ab elian braid group B 3 . We show that the central full twist acts as an inescapable“ elastic lock” localized in the shared Y- gate throat, regularized by the constituent centrifugal fl o or (R 0 0 . 631 fm). We contrast this with the unstable meson sector governed by the abelian B 2 g ro up, and discuss the observational and mathematical status of the model.
