Many upstream plugins publish no tags at all, so a tag-only installer cannot manage them. - Add a branch spec field, mutually exclusive with tag and validated the same way - Build archive/refs/heads/<branch> URLs for branch specs - Refetch a branch only on :ArtiPackUpdate or a forced sync, never from cache - Record the branch, archive digest and fetch time in the lockfile - Report a branch plugin as tracked and fetched, never as up to date
