Theta Modular Boundary Anomaly Is the Neutral Half Carrier

Splitting the theta Mellin integral at its self-dual point gives

$$\Lambda(s) = I(s)+\frac1{s-1}-\frac1s,$$

with $I(s)=I(1-s)$ entire. Canonical completion maps the two continuation currents to

$$\frac12s(s-1) \left( \frac1{s-1}-\frac1s \right) = \frac12.$$

Thus the neutral half carrier is exactly the scalar image of the completed archimedean boundary anomaly. The archimedean lane is now classified: flat bulk, rank-two relative boundary, and rank-one constant compression. None orients zeros. Any remaining force must be a pre-compression coupling to arithmetic boundary registers.
