1395 — Weil Gives the Global Prime–Gamma Boundary Morphism

Epistemic-graph event: 1439.

For logarithmic test functions, let $g^*(u)=\overline{g(-u)}$. The Weil explicit-formula functional has arithmetic side

$$W(h)=W_\infty(h)+W_{\rm endpoint}(h) -\sum_{n\ge2}\frac{\Lambda(n)}{\sqrt n} \bigl(h(\log n)+h(-\log n)\bigr)$$

and spectral side

$$W(h)=\sum_\rho \widehat h\!\left(\frac{\rho-1/2}{i}\right).$$

Therefore

$$\boxed{\mathrm{RH}\iff W(g*g^*)\ge0 \text{ for every admissible }g.}$$

The radical quotient of

$$\langle g_1,g_2\rangle_W=W(g_1*g_2^*)$$

is the canonical global, cutoff-independent prime–gamma boundary quotient. It is source-derived and unconditional, but indefinite until RH positivity is proved.

Its formal Cauchy-feature Gram kernel is exactly the $\Xi$ Pick kernel of Ledger 1391. The remaining analytic gate is extension from compact test functions to those resolvent vectors, followed by closability, compact resolvent, and the regularized determinant theorem.

Scope: the global morphism and radical quotient are derived; positivity/RH and the closed self-adjoint operator remain unproved.

Durable verification:

• Research packet: `research/grothendieck/weil-explicit-formula-global-boundary-morphism.md`.
• Explicit-formula, convolution-square, radical-quotient, and formal Cauchy-kernel comparison.
• Epistemic-graph event: 1439.
