The Theta Tail Is the Exact Anti-Invariant Repair Current

For the source split

$$\Phi=\phi_1+\tau,$$

completed evenness gives the exact analytic incidence equation

$$\mathsf A\tau=-\mathsf A\phi_1, \qquad \mathsf A=\frac{1-\mathsf R}{2}.$$

Thus the higher-label tail carries the complete opposite of the primitive reflection defect. Every odd seam-jet cancellation is a derivative shadow of this one identity.

This explains why the tail can be pointwise tiny on the positive chamber yet coherence-essential: the repair lives in a two-chamber anti-invariant coordinate erased by one-sided value control.
