 Use this for:
 
 - convex decomposition results
+- primitive collision proxies
 - collision-only meshes
 - format conversions
 - normalized or cleaned variants
 
 If a derived asset keeps a direct dependency on a raw asset, reference the raw asset in metadata and preserve provenance links.

 ## Required per-asset files
 
 - Source asset files, preserving upstream structure where practical.
