GitHub is a pruning push mirror of Gitea, so a tag created by "gh release create" belongs to no upstream ref and disappears on the next synchronisation, orphaning the release and its archives. Document the order that survives it: push the tag to Gitea, wait for the mirror, verify the tag on GitHub, publish with --verify-tag. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
