Data and code for "Wavevector selection beyond conformation positive definiteness"

This archive provides the machine-readable data, exact symboliccertificates, finite numerical verification records, replay scripts andfigure-generation sources supporting the manuscript “Wavevector selectionbeyond conformation positive definiteness”. It includes deterministic checksof the fixed-direction stability criterion, planar directional-selectiondata, three-dimensional full-sphere regressions and reference-pathfinite-inertia certificates, together with the data used to generate themain and supplementary figures. The numerical records are frozen-coefficientuniform-symbol checks, not inhomogeneous-flow DNS. Reproduction instructions,integrity manifests and the provenance boundaries of registered legacyvalidation records are included in the archive.
