CDUFD Supplementary Material I: Formal Derivation of the Electroweak Critical Point

This is the first supplementary material of the CDUFD qualitative framework. Based on axioms A1–A5 and the A5-anchored parameters, we formally derive the universality class (3D Ising), critical exponents (ν=0.63002, $z=2.024$) and bare energy scale (Λ₁₄=27.8 GeV) of the electroweak critical point. Comparing the bare scale with the observed Higgs vacuum expectation value $v=246$ GeV we define a structure factor C=v/Λ₁₄≈8.85, whose theoretical origin is left as an open problem (critical amplitude ratio, group‑theoretic factor, or radiative corrections). From the Langevin equation we derive the Fokker–Planck equation and then, via a Madelung transformation, obtain the Schrödinger equation; the Wallstrom condition and the Born rule remain open problems. The paper introduces no new assumptions; all unresolved issues are explicitly identified.
