Physics as the Topology of a Non-Invertible Projection

A single structural condition — a globally conserved Noether flow under restricted accessibility — forces by necessity, without additional input, the Majorana bulk field, the rank-5 non-invertible projection, and the representational manifold ℝ⁴ × S¹(τ). The physical mechanism: the conserved flow carries a compact internal phase χ ∈ S¹, the zero mode. At the projection interface this zero mode becomes evanescent. What does not cross does not disappear — it returns as boundary tension λ|Ψ|^(4/3) and as the discrete invariant structure of the observable world. From this single evanescent zero mode, with no free parameters, emerge: the fine-structure constant α⁻¹ = (F₅ + F₄√5)² = (5 + 3√5)² ≈ 137.08, the gauge group U(1) × SU(2) × SU(3), the Weinberg angle sin²θ_W = 3/13 (unconditional theorem), charge quantisation 6Q ∈ ℤ, the discrete coherence renormalisation law Bₖ₊₁ = 2B_k2/3, and time as the irreversible ordering of coherence loss. The absolute dimensional scale belongs to ker(Π*) by a model-independent structural theorem (DOI: 10.5281/zenodo.19402305). A single external anchor is necessary and sufficient: R∞. The spectral factor F_nm = (2√5)^(5/2) φ²/(9π²) closes the dimensional cascade R∞ → f_τ → R₅ → G → ℓ_P → T_CMB (P13, DOI: 10.5281/zenodo.19392738). This is the axiomatic foundation of the QGT series.
