VLA training

Main blocker

Hardware, latency, dependencies, and checkpoint loading are not pipeline-tested.

Next check

Verify repository and artifact licenses.

Adoption evidence

Artifact, reproducibility, and evaluation evidence most relevant to adoption.

Published evaluation

Artifact availability

Useful

Checkpoint files were verified in the official repository metadata.
