The Tail–Seam Synthesis Supplies the Pair Current but Not Its Orientation
For complete labelled tail–seam atoms u_n, the synthesis operator U
canonically supplies the missing pair current as K=U*U, with logarithmic
kernel
This retains the off-diagonal interference needed to reconstruct seam periods. Positive Fock formation supplies the labels; analytic synthesis and polarization supply their overlaps.
However, simultaneous prime transport preserves the kernel. It does not yield the modular factor required to orient the reciprocal sectors. Pairwise observability is therefore closed, while relative additive-Haar versus multiplicative-Haar orientation remains open.
