4192 — The Common Affine Forcing Both Saves Zero-State Meaning and Obstructs Pathwise Sewing
The common Fourier--Tate source frame was already derived:
At a completed scalar zero, , and the affine endpoint Gram is
But for and , the same equations give
Therefore endpoint cancellation does not extend to pathwise cancellation. The same forward forcing incidence both preserves the full zero-state meaning and obstructs conservative reciprocal sewing.
The missing capability is a source-authorized variance reversal or lower adjoint incidence, not another positivity formulation.
