Abstract

This ZQCM-B8-Final-V4-EN archive updates Higgs mass derivation by closing the GUT coupling λ_GUT via T13-3′ five-theorem joint locking. All geometric constants from S³ spectral geometry and B₄ Coxeter root systems are fixed without free parameters. The rigid theoretical Higgs mass output is 128.11 GeV within the structural interval [110,150] GeV, showing a 2.4% mild tension with PDG measurement. This version upgrades m_H from post-hoc candidate to full theorem layer result, unifying B0–B7 and T13 theoretical chains.
