A certified 2.68 TeV gap in the closed-form map of the compactification scale of SU(7) grand gauge-Higgs unification: the inverse map, its named no-go certificates, and the invariant its two observables cannot see (Part VIII).

Reproducible verification for the paper Gap-protected spectral invariants on T^d/Z_2 (doi:10.5281/zenodo.20597195)

An upper bound on the compactification scale of SU(7) grand gauge-Higgs unification, and the dijet angular distribution that tests it (Part VII).

Schur functions at (1,-1,t,1/t): a closed form on the non-identity component of O(4) (Part IV).

What the Higgs Potential Cannot See: bulk matter that cannot help select a boundary condition (Part V).

Three Gates to a Quark Generation: an exact criterion for which SU(4) representations contain the Standard Model (Part II).

Anomaly- and tadpole-compatible fermion completion of 6D SU(4) gauge-Higgs unification (exact, Lean-checked) (Part I).

A centre-charge selection rule for the Wilson-line potential: the fundamental domain of gauge-Higgs unification is representation-dependent (Part III).

An instrument for gauge-Higgs unification and the home of a seven-part series. One bulk model, five sections over it: the compactification scale (VII), the anomaly and proton bill (VI), the selection rule (III), a calculator and an eta-meter (IV-V). Every output labelled theorem, verified, measured or unknown. One HTML file, no network.

Proton decay in SU(7) grand gauge-Higgs unification: an obstruction, its minimal escapes, and the one row of their Table 1 that can pay for them (Part VI).
