1380 — Completed Scattering Phase Collapses to the Identity

Epistemic-graph event: 1414.

Let

$$G(s)=\pi^{-s/2}\Gamma(s/2),\qquad D(s)=\frac1{\zeta(s)}.$$

On $s=1/2+it$, the natural prime and archimedean unitary ratios are

$$S_p(s)=\frac{D(s)}{D(\bar s)} =\frac{\zeta(\bar s)}{\zeta(s)}, \qquad S_\infty(s)=\frac{G(\bar s)}{G(s)}.$$

The functional equation

$$G(s)\zeta(s)=G(\bar s)\zeta(\bar s)$$

forces

$$S_\infty(s)S_p(s)=1$$

identically. Apparent zero-over-zero singularities cancel meromorphically. Consequently the scalar unitary boundary condition

$$\det(I-S_\infty S_p)=0$$

selects the entire critical-line continuum, not the Riemann zeros. Declaring the undefined factors at zeros to be exceptional eigenstates would insert the target set unless an independent operator-domain defect forces it.

Scalar scattering loses the amplitude information where $\Xi(t)$ vanishes. The surviving boundary must therefore glue prime and archimedean data before scalar determinant reduction, in an operator-valued defect space, extension, or canonical system.

Scope: this falsifies the natural scalar phase-only quantization, not operator-valued scattering with nontrivial defect multiplicity.

Durable verification:

• Research packet: `research/grothendieck/critical-line-scattering-phase-collapse.md`.
• Exact functional-equation cancellation on the critical line.
• Epistemic-graph event: 1414.
