4321 — Two-Triangle RH Comparison and Its Native Boundary

What each triangle computes

The bare triangles act on coefficient amplitudes. Arithmetic enters through an explicit added analytic decoration on a fixed test/antidual register, not through the native arrows alone.

Let $\mathcal T$ consist of smooth functions with finite seminorms

$$p_{k,m}(f)=\max_{j\le m}\sup_x e^{k|x|}|f^{(j)}(x)|$$

for all integers $k\ge1,m\ge0$. Write $Ff(u)=\int f(x)e^{-iux}\,dx$. A Hermitian source form $b$, conjugate-linear in its first argument, defines the continuous weak operator $(W_b g)(f)=b(f,g)$ into the continuous antidual. Its edge operation is the reversible shear

$$U_b(f,\ell)=(f,\ell+W_bf).$$

Starting from $(f,0)$, the arithmetic triangle follows $AB,BC,CA$, with edge labels endpoint $E$, gamma $\Gamma$, and signed prime-power term $P$. It produces $(f,W_Af)$, where $A=E+\Gamma+P$. The scalar readout is

$$\begin{aligned} b_A(f,f)={}&\operatorname{Re}\left(\overline{A_-(f)}A_+(f)\right)\\ &+\frac1{4\pi}\int_{\mathbb R} \left(\operatorname{Re}\psi(1/4+iu/2)-\log\pi\right)|Ff(u)|^2\,du\\ &-\sum_{n\ge2}\frac{\Lambda(n)}{\sqrt n} \operatorname{Re}\langle f,T_{\log n}f\rangle, \end{aligned}$$

where $A_\pm(f)=\int f(x)e^{\pm x/2}\,dx$ and $T_rf(x)=f(x+r)$.

The spectral triangle follows $BA,AD,DB$, with labels $-E,Z,E$. It subtracts and restores the endpoint register around the full divisor evaluation, producing $(f,W_Zf)$, with

$$b_Z(f,f)=\frac12\sum_\rho m(\rho) \overline{Ff(\overline{u_\rho})}Ff(u_\rho), \qquad u_\rho=\frac{\rho-1/2}{i}.$$

The sum retains complex nodes and holomorphic multiplicities. It is not replaced by an absolute square at a complex node.

What the common edge identifies

The shared edge identifies one test frame and the chosen endpoint operator, with inverse operations on $AB$ and $BA$. The shared analytic interface fixes Fourier conventions and the half-divisor normalization. This endpoint assignment is noncanonical: compensating changes to other edge labels preserve both face outputs.

The classical explicit formula, not the shared edge, supplies $b_A=b_Z$. Following both faces forward computes their sum. Comparing them requires the inverse second face; the composable path $AB,BC,CA,AB,BD,DA$ computes $U_{A-Z}$, the identity at the exact source level. Independently computed finite midpoints retain a bounded nonzero discrepancy rather than being silently equated.

What survives in both structures

The protonlike and neutron carriers admit the same added analytic register through metric-correct normalized native tags. Exact restrictions of dimensions three and fifteen were checked, together with negative and complex-Hermitian controls. The neutron metric is retained.

This does not identify the complete native processors. The inherited forms have only fourteen positive directions, excluding a fixed linear encoding of the certified positive fifteen-test family without enlargement. In the selected one-plane enlargement, the three-stage $G-N$ ranks remain six and thirty-three. Moreover the native clock satisfies $W^5=W^2$, whereas a nonzero source shear $U=I+N$, $N^2=0$, satisfies $U^5-U^2=3N\ne0$. These obstruct the corresponding full-stage equivalence and injective clock intertwining; they do not exclude every alternative enlargement.

Covariance, quotient, and the RH condition

Every source form is invariant under simultaneous real translation of its two tests. On the antidual, $D_r\ell(f)=\ell(T_{-r}f)$ gives $W_bT_r=D_rW_b$. Signed covariance is unconditional: synthetic off-axis controls preserve the signed pairing while failing positive unitarity.

On the distinct divisor nodes, introduce the auxiliary space

$$K=\ell^2(\{u_\rho\},m/2),\qquad (\mathcal Ef)(u)=Ff(u),\qquad (Cv)(u)=v(\overline u).$$

Then $b_Z(f,g)=\langle C\mathcal Ef,\mathcal Eg\rangle_K$, where $C$ is a linear self-adjoint permutation involution. Gaussian-polynomial localization gives density of $\mathcal E(\mathcal T)$ in $K$, and hence $\operatorname{Rad}b_Z=\ker\mathcal E$. The isotropic cone cannot replace the radical without positivity.

If a nonreal node exists, its conjugate pair supplies a negative signed direction, approximable by test evaluations. If all nodes are real, $C=I$. Thus positivity on every test is equivalent to RH; this establishes the comparison's logical content, not positivity itself. Under RH the positive radical quotient completes to $K$, with the self-adjoint multiplication generator and compact resolvent described in the companion note.

Multiplicity remains a scalar weight in this model. A node of multiplicity $m$ does not acquire an $m$-dimensional eigenspace: repeated scalar evaluations occupy only the diagonal of $m$ copies. A multiplicity-resolved determinant requires additional justification.

Scope

The same signed analytic RH comparison survives beside both native structures. No all-test positivity, RH proof, native arithmetic execution, full native processing equivalence, or zeta determinant identity is asserted. Infinite-dimensional statements are analytic arguments, not machine-formalized theorems; the exact finite controls do not certify them by extrapolation.
