Substrate profile

Definition

A classification of a model deployment by nine properties, used instead of asking only whether the model is open or closed. The properties are weight access, runtime control, update authority, version stability, revocation, substitutability, observability, standing, and dependency. Two deployments of the same model can carry entirely different profiles.

It matters because the governance burden follows the profile rather than the license. The profile says which properties the institution holds itself and which it has left with a provider, which is what determines its real institutional reversibility and its dependency state.

StructuralVisibility

Tests that show it is in place

  • All nine properties are recorded per deployment, not per model.
  • A property held by a provider is named as such, with the contractual basis for relying on it.
  • The profile is re-scored when the provider, contract, or hosting arrangement changes.

Evidence to keep

  • Artifact: A substrate profile record scoring all nine properties for the deployment.
  • Behavior: A procurement decision changed after the profile revealed no revocation control.
  • Metric: Count of the nine properties held by the institution rather than the provider.
