Overview
Abstract
We obtain a joint finite-rank approximation law for the complete Birman–Schwinger family of a constrained theta-weighted Weil operator. At each fixed absolute error tolerance, the required rank is at most C exp(C√log(1/ε)) as the positive resolvent parameter ε tends to zero. The construction pays the complete paired arithmetic tail, high-frequency block and mixed localization errors. It gives a corresponding bound on the entire negative spectral projection and implies that the negative eigenvalue magnitudes decay as C exp[−c log²(n+1)]. Thus the full negative part belongs to every Schatten class. We also give effective simultaneous prime-phase returns and prove signed high-frequency saturation uniformly in a complementary growing-cutoff regime, retaining the exact polar constraints and the inverse-theta packet norm. The joint rank and saturation regimes have different parameter scales.

Scope of the work
The results use the specified two-row constrained minimal-form realization H=A+B. The joint approximation-rank law is at fixed absolute tolerance. Signed saturation is uniform under a prescribed envelope log M=o(log log log L), a different parameter regime.
