All Ramanujan Packets Are Shadows of One Schwartz--Bruhat Distribution

Multiplicative Haar measure on $\widehat{\mathbb Z}^\times$ defines a canonical distribution $T_\times\in\mathcal S'(\mathbb A_f)$, despite having no additive-Haar density.

Finite sieve measures converge to it eventually on every Schwartz--Bruhat test. Its conductor-$Q$ Fourier coefficient is

$$\langle T_\times,\chi_{k/Q}\rangle = \frac{c_Q(k)}{\varphi(Q)}.$$

Thus every Ramanujan packet is a finite shadow of one completed distribution. The angular conductor completion is solved in the rigged category; the weak escape arose only from demanding an additive-$L^2$ vector. The radial valuation/Fock tower remains a separate retained component.

The remaining RH theorem is solely the coupling of this finite-adelic distributional correspondence to the half-normalized archimedean tempered boundary.
