Artifact policy

Git stores code, schemas, documentation, small fixtures, and manifests. It does not store model weights, checkpoints, rollout traces, large datasets, generated results, or mutable experiment directories.

Required reference fields

Every external artifact reference records:

  • Immutable URI or revision
  • SHA-256 digest
  • Media type
  • Size in bytes
  • License or access terms
  • Producing run when applicable

Claim-bearing inputs may not use mutable aliases such as latest.

Intended storage

  • GitHub for source, schemas, small fixtures, and manifests
  • Hugging Face for released datasets and models with cards
  • Object storage or DFS for checkpoints, rollouts, traces, and large results
  • OCI registries for containers pinned by digest
  • Experiment trackers for live telemetry, not canonical evidence

Machine-specific storage paths and hostnames must not appear in released manifests. GitHub Releases or a research artifact repository should carry compact experiment bundles. Hugging Face repositories should carry models and datasets with model or dataset cards.
