texture_source_audit() returns a source-audit registry for planned texture
and particle-size systems. It is not a texture polygon dataset and does not
contain polygon coordinates, class vertices, or class tables.
Details
primary_source_status = "needs_verification" means that candidate sources
have not yet been reviewed as package-ready primary documentation. Future
built-in polygon datasets should be reconstructed from original official or
academic sources, cited, reviewed, and tested before implementation.
