      # Upstream actions/checkout builds the clone URL from the server's origin
      # and drops a subpath such as /git (actions/checkout#1370, #1242), so it
      # cannot clone from imsc.uni-graz.at/git. ischanx/checkout keeps the path.
      # Pinned to the commit of its v6.0.2 tag; its v4 tags lack the fix.
      # Actions use full GitHub URLs: short names resolve against the
      # instance's default actions registry, not GitHub.
