  # One job makes the draft, before the builds: three matrix jobs each running
  # "view || create" could race and make duplicate drafts. The draft is tied to
  # the pushed tag (the tag must already exist on GitHub, then tag_name is set
  # explicitly), so scripts/publish-release.sh and `gh release upload` find it
  # by tag. It is created with the REST API so the id comes straight back: the
  # release list can lag a fresh draft (v0.4.2's first run found nothing and
  # PATCHed releases/ with an empty id). tests/test_release_workflow.py runs
  # this step against tests/fakegh.
