Critical Coordinate Is the Antisymmetric Completed Boundary Channel
Retaining the two theta continuation currents separately through canonical completion gives
Its symmetric and antisymmetric coordinates are
Thus the centered critical coordinate is exactly the boundary direction lost when the rank-two continuation packet is compressed to the neutral half carrier. The critical line is the locus where the two reciprocal boundary components have equal real share. The coefficient in the proposed conservation law is twice the real boundary polarization.
This explains the offset and two-sector geometry but does not constrain the divisor. A proof still requires a faithful pre-compression coupling to the antisymmetric channel, stable against both new completion kernels and reduced minimum-modulus collapse.
