2850 — Reciprocal Sewing Makes the Gaussian Seam Port an Observable, Not a Barrier
For symmetric and antisymmetric half-line amplitudes (X=H_++H_-) and (Y=H_+-H_-), reciprocal sewing of the Gaussian number current gives
The seam doubles symmetrically and cancels antisymmetrically. At (X=0), both number channels remain well-defined and generally nonzero. Thus the seam port retains information lost by the scalar readout but does not exclude its zero. The finite additive oscillator-ladder route is closed; any further force must couple multiplicative arithmetic incidence to the relative route phase.
