ZQCM‑B9‑Final‑V6‑EN

This ZQCM-B9-Final-V6-EN archive fully locks three neutrino masses and proton decay lifetime within the S³ spectral geometric framework. Based on rank-2 seesaw mechanism, T14 residual correction and cross-scale rank-jump theorem, we derive rigid neutrino mass values: \(m_1=0.0024\ eV\), \(m_2=8.11×10⁻³\ eV\), \(m_3=0.0475\ eV\), with total sum \(∑ m_ν=0.0580\ eV\) consistent with cosmological bounds. The structural lifetime window for proton decay \(τ(p→ e^+π^0) ∈ [1.2×10³⁶,2.1×10³⁷]\) years is uniquely fixed via Spin(10) leptoquark mass derivation. No free adjustable structural parameters are introduced.
