Contract

Portable vectors with enough identity to fail safely.

Ster artifacts are deterministic JSON, not Python pickle or framework-owned tensor objects.

Recorded identity

  • Artifact schema version and Ster product identity.
  • Model id and resolved model revision.
  • Trait, training method, and hidden width.
  • Layer-indexed normalized directions.
  • Training accuracy and projection margin.

Evaluate

Shell
ster evaluate \
  --model meta-llama/Llama-3.2-1B \
  --pairs pairs.json \
  --vector truthful.ster.json

ster inspect truthful.ster.json

Reproducibility

Use an immutable Hugging Face commit with --revision <sha> when an artifact must remain reproducible after upstream model updates.
