Mathematical Content

Boundary Completeness

All C(4,2) = 6 pairs of primitive sectors {D, A, B, C} satisfy commuting Hartogs squares in H_∂[ω]. Each pair has a well-defined cross-coupling κ(X,Y) that is a rational function of ι_τ.

The 6 pairs: DA, DB, DC, AB, AC, BC. Together with 4 self-couplings and the closing identity, all 10+1 coupling relations are determined by ι_τ alone.

Cross-Coupling as Naturality

For each sector pair (X,Y), the cross-coupling κ(X,Y) is the leading spectral weight of a natural transformation η_{X,Y} between the two sector functors. Naturality (= functorial coherence) replaces gauge invariance as the organizing principle.

ι_τ Mediates All Ten Couplings

Every coupling constant in τ (self-couplings, cross-couplings, α, G, and the closing identity) is a rational function of the single master constant ι_τ = 2/(π+e).

4 self-couplings: κ(D;1), κ(A;2), κ(B;1), κ(C;3) 6 cross-couplings: κ(D,A), κ(D,B), κ(D,C), κ(A,B), κ(A,C), κ(B,C) Total: 10 couplings, ALL from ι_τ.

Boundary Unification Principle

Unification does not require a larger gauge group (like SU(5) or E₈). The sectors are already unified at the boundary-character level: they are different readings of the SAME H_∂[ω]. What orthodox physics calls “unification” is recognition that all sectors share a common algebraic substrate.
