The outgoing-shortcut terminal Step-4 charge #
This file closes the local analytic seam at a shortcut terminal block for an
arbitrary partial pairing. It follows paper §4.2, Step 4 in the required
order: the outgoing endpoint is Fourier-integrated exactly, the complete
signed primitive sum is integrated into the ordinary primitive kernel, and
only then is 𝓔 symmetry used to expose the cosine defect. The final bound
therefore uses the ordinary primitiveKernelMajorant, with the paper's one
ε⁻² loss for this endpoint; no inserted kernel occurs here.
No trace or routing structure is introduced. The input is precisely the
existing R324ShortcutStopTraceAssembly, which leaves the terminal shortcut
visible after the proper-prefix reduction.
Exact endpoint phase #
With the paper gap orientation u = first - last, the outgoing shortcut
coefficient is the free Green multiplier times the genuine phase defect.
This is an exact identity, before taking a norm.
The core left by outgoing endpoint Fourier integration is one genuine predecessor edge times the complete signed primitive density.
Integrating the internal coordinates of the outgoing-erased terminal core produces the ordinary heterogeneous primitive kernel. The complete finite primitive-pairing sum remains inside the integral until this exact identity is applied.
Fixed-first, fixed-gap form of the shortcut endpoint operation for an
arbitrary stopped terminal R324WithinHalfStepContext. The y integral
is performed first, then the complete signed primitive sum is integrated
in the internal block coordinates.
After the exact endpoint and internal-coordinate operations, integrating the terminal gap leaves precisely the ordinary primitive phase defect. No absolute value has yet been taken.
𝓔 symmetry is applied only after both endpoint and interval variables
have been removed. The resulting kernel is the ordinary J, not the
inserted J̃.
Certificate-ready numerical endpoint charge. The Fourier multiplier
⟨k⟩⁻² remains explicit and the terminal primitive block is charged by the
ordinary Proposition 4.1 majorant.
The usable certificate-scaled form of the outgoing shortcut charge.
The stopped block's internal edges carry their actual inverse-square
constants in certificate; Proposition 4.1 is applied only after those
constants are normalized out.
