Overview
Abstract
We classify inverse energies of fixed frequency sources in a reciprocal-theta realization of the Weil form and compare two positive receivers on identical constrained spaces. Regular profiles have an exact archimedean inverse-Gram limit given by their full Fourier-dual matrix, unchanged by any fixed finite collection of known derivative-null and polar rows. A nonzero frequency-zero trace produces exactly one divergent direction, of order log log(1/ε) on the original polar space. For the complete positive part of every fixed arithmetic cutoff, every direction of an independent negative-band source family instead outgrows every fixed power of log log(1/κ), even after those known rows are removed. We give a complete eight-feature application at cutoff 13. For comparison with derivative sources, we identify their fixed-family normalized leading matrix by an exact outer-Hardy and Cauchy formula and sharpen the admitted growing-family range to an explicit onset asymptotic to 4n log n. The proofs preserve complete theta tails, mixed covariances and the original minimal form domains.

Scope of the work
Exact fixed-frequency inverse-Gram limits after fixed known rows; rank-one frequency-zero singularity; all-direction complete positive-receiver divergence on the same source; fixed-family derivative leading matrix with exact outer-Hardy/Cauchy formula, inverse, determinant and exponential conditioning bounds; certified eight-column limit matrices and fixed-row Blaschke prices.
Reproduction notes
The 33-page paper is accompanied by complete editable LaTeX sources, five portable programs and exact mathematical data in a 31-member publication package. The programs check the derivative estimates, endpoint and admission controls, eight-feature approximation, directed outer-factor integrals, all entries of the eight-by-eight limit matrix and its inverse, and fixed-row identities. Normal and optimized outputs agree. The manuscript supplies the complete analytic proofs and all-frequency tail bounds.
