        # 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 the whole magnet/ package. This job
  # installs the CPU inference stack and actually imports + tests magnet/, catching packaging and API
  # regressions (e.g. a clean-install `import magnet` failure). The weights-gated inference tests still
  # skip here (checkpoints are not in the repo); everything else runs.
