3128 — Scale Pullback Closes Prime-Window Escape onto the Fifth Wall

Compactify prime scale by

$$r=p^{-1}.$$

The reciprocal-window family extends to the large-prime boundary with

$$W_0=-1.$$

Fourier transform sends this boundary fiber to $-\delta_0$. Thus the widening-window escape closes onto the already derived constant–delta plane: the fifth wall is the Fourier-stable boundary at infinite prime scale.

The correct completed source is the pullback of the five-cell family along the labelled map $p\mapsto p^{-1}$, retaining the graph $(r,W_r)$. Completing only the unlabelled image forgets which source direction produced the constant limit.

Scope

The pullback preserves scale provenance but does not regularize primitive or prime-square sums. Their remaining defect is now typed as incidence in the boundary fiber at $r=0$.
