  # The command line and the refitting of fastparameterselection/const.py both
  # go through fastparameterselection/nd.py, which imports sage.all.

  # Sage runs through `docker run` rather than a job-level `container:`. The
  # image runs as the unprivileged `sage` user while the runner owns its
  # workspace as root, so actions/checkout fails inside it with EACCES on
  # /__w/_temp. Running the container as root is not a way out either: Sage
  # ignores `--python3` as root and drops into its REPL. Checking out on the
  # host and mounting the tree read-only avoids both.
