Overview

Abstract

We develop sharp all-order bounds for coupled permanent cofactors and occupation-resolved variance and curvature constraints for complex positive semidefinite Gram matrices. A uniform six-row theorem proves actual compensation whenever one selected occupation is at most 1/401. Consequently an order-seven PSD matrix satisfies self-Chollet if one normalized off-diagonal squared modulus is at most 1/401; the two-factor consequence requires both factors to meet this condition. Aligned cofactor occupations give a sharp retained-curvature reserve, with coefficient 19/240 at six rows, uniformly optimal also on active rank-six and rank-five correlation bases. Exact projection overlap couples trace and occupation floors without double counting. Balanced coherent-column and covariance-deficit tests give further sufficient domains. Proofs retain complex phases, singular boundaries and kernel mixtures. The generic rank-six compensation inequality and unrestricted Chollet conjecture remain open.

Scope of the work

The uniform 1/401 domain and order-seven weak-pair theorem, actual cofactor coefficient constraints, sharp curvature reserve, projection-overlap bounds and balanced sufficient domains are proved with their stated hypotheses. The generic rank-six compensation problem remains open. The 2025 Sa-nguansin–Rodtes full proof was inaccessible for comparison; no exhaustive containment or first-ever priority is claimed. Classical CLL, scaling and projection tools are attributed. Internal AI-assisted review is not external human refereeing.

Reproduction notes

The complete 34-page manuscript and 19-member package contain editable LaTeX sources, seven standard-library Python checkers, exact rational fixture data, reader/build instructions, citation metadata and public checksums. Fourteen extracted normal/optimized checker runs passed. An isolated source rebuild reproduced all mathematical text and page geometry. Finite computations corroborate identities and constants; universal claims rest on the analytic proofs.
