        # Tests run against a synthetic fixture; tests requiring the large
        # Hugging Face-hosted .hdf5 files skip automatically when those files are absent.

  # The job above never installs torch, so conftest.py skips tests/ (the magnet API tests). This job
  # installs the CPU inference stack, verifies the pip-installed package imports from a clean directory
  # (catching packaging regressions like a dropped eqV2/Jd.pt), then runs the tests/ API tests. The
  # weights-gated inference tests still skip here (checkpoints are not in the repo); everything else runs.
