What

A call now counts as a publish when it only removes files or only sets live files, not just when it lists files to upload, so removal-only updates go through.

Details
  • The duplicate-path error was rewritten from a terse note into an instruction naming the repeated path.
  • Publish responses carry a marker for an artifact that is gone and a flag for a 403 caused by the artifact belonging to another organisation.
Evidence

is listed more than once in

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
