1392 — Every Prime Mode Adds a Negative Pick Direction

Epistemic-graph event: 1434.

For $\operatorname{Im}z>1/2$, the functional equation puts $s=1/2-iz$ in the Euler half-plane and gives the finite-cutoff prime Weyl term

$$M_C(z)= -i\sum_{n\in C}\Lambda(n)n^{-1/2}e^{iz\log n}.$$

Adding one mode of weight $a>0$ and length $L>0$ changes the diagonal Pick kernel at $z=iy$ by

$$\delta K(iy,iy) =-\frac{ae^{-yL}}{y}<0.$$

Therefore prime cutoff refinement cannot be realized by adjoining positive Hilbert-space boundary features. Each prime-power mode adds a negative direction to the indefinite Pick preshape.

Any positive boundary must arise only after a global, cutoff-compatible gamma–prime quotient. Holding the archimedean channel fixed while adding positive prime fibers is exactly falsified.

Scope: monotone positive prime-feature refinement is ruled out; an indefinite system with a source-derived positive completed quotient remains possible.

Durable verification:

• Research packet: `research/grothendieck/prime-pick-cutoff-antimonotonicity.md`.
• Euler-half-plane Weyl expansion and one-mode diagonal Pick calculation.
• Epistemic-graph event: 1434.
