SOMETHING TO NOTICE
Inside the workshop
This public edition selects precomputed shapes built and measured with native USD BRep. The native engine does not run in your browser. Seven body recipes, three head types, three ballast types and nine ballast positions form a finite library. Rejected native recipes cannot score. Save/reload checks allow 0.1% volume difference and 0.01-unit centroid difference; derived mesh volume must agree within 2.5%. These are software checks, not physical validation.
