Paper 1 - Geometric Origin of the Standard Model via Internal-Frame Redundancy

Paper 1 of the Abebe Carrier Framework under Master Map II. Introduces the geometric origin of the Standard Model from internal-frame redundancy on a Spinᶜ(4) manifold. Establishes the four axioms (A1–A4) and proves that the unique stable configuration yields the full SM gauge group SU(3)×SU(2)×U(1), exactly three chiral generations, charge assignments, and hierarchical Yukawas with no free parameters. Part of the complete series (Papers 0–5) with Global Closure Appendices A–G. (Keywords: Carrier Framework, Master Map II, internal-frame redundancy, SM-Island, topological defects, X=2 bifurcation)
