ZQCM‑T14‑Final‑V3‑EN

This archive ZQCM-T14-Final-V3-EN solves the neutrino mass suppression problem via \(B_4 ⊃ B_2 × D_2\) chiral projection mechanism. It derives the chiral compression factor \(Πchiral=2-31/32\) from Weyl stabilizer group isomorphism and binary information partition axiom A3-⑥, which reduces the bare seesaw \(m_3ˢᵏᵉˡ\) to physical \(m_3=0.0475\ eV\) (fully theorem-locked). The zero-mode mass \(m_1=0.0024\ eV\) originates from cross-scale rank-jump lifting, classified as structural corollary pending full Clebsch-Gordan calculation. \(m_2=0.0081\ eV\) remains unchanged due to coset homology constraints. The total summed neutrino mass \(∑ m_ν=0.0580\ eV\) matches cosmological bounds. All derivations rely on zero adjustable structural exponents, with clear tier classification for rigorous theorems and unresolved long-term algebraic tasks.
