    # This job, in contrast to "dist" in ci-macos.yml,
    # does not use "configure --enable-download-from-upstream-url"
    # (the default since #32390).
    #
    # In this way, we check that all necessary package tarballs
    # have already been uploaded to the Sage server at the time
    # of pushing a release tag.
    #
    # It also uses "bootstrap -D", thus checking that the "configure"
    # tarball has been uploaded to the Sage server at the time
    # of pushing a release tag.
