Deleting the manifest by its digest removed every tag on it, and reproducible builds share a digest between a branch's tagged version and the trunk's numbered one, so a branch's end deleted the trunk's image (security review F1). The fake catalog now deletes by digest as the store does; a store that cannot delete a tag alone removes nothing and the removal is refused.
