Reciprocal Maslov Divergence Cancels Before Arithmetic Currents
Reciprocal Fourier–Tate sectors carry signed normalized areas (t) and (-t). Their floor grades satisfy
away from integer crossings, and sum to zero at an exact crossing where the centered minor vanishes.
The centered convention (\mu(t)=\lfloor t\rfloor+1/2) is reciprocally odd: (\mu(-t)=-\mu(t)). Thus the unbounded parts of the two sector grades cancel automatically. The half-unit is the forced endpoint convention for reciprocal crossing counts.
Primitive and prime-square currents are therefore not needed to renormalize the extensive Maslov grade. Identifying them as Maslov counterterms without a separate source incidence would be a typing error.
Only the aliasing jumps and their labelled relationship to the physical boundary line remain. Universal metaplectic coherence cannot distinguish theta from hostile reciprocal sources and carries no RH orientation by itself.
