Opposite-Oriented Reciprocal Sewing Cancels the Faithful Bivector Boundary Flux
In the normalized finite Fourier model, the source augmentation bivector and its control-relative reciprocal image have equal, nonzero energies. They are not identified or erased.
The two reciprocal sector packets carry opposite boundary orientations. Therefore their relative boundary form is the difference of these equal energies and vanishes exactly.
This supplies the first faithful boundary-repair mechanism: the missing opposite flux is the reciprocal copy itself. The result motivates constructing the full relative mapping-cone Green identity before introducing any new prime-weighted repair.
