What
Uploading a file to an artifact whose extension does not indicate what the file holds now requires your approval and cannot be approved by the auto-permission classifier. The same check also stops that upload from granting blanket coverage for later uploads to the artifact.
Evidence
the path’s extension does not say what the file holds
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
