Architecture
Open a layer to see what it does, what enters it and what leaves.
GOV
Governance
Who owns which data, which model version made which decision, and how any number can be audited.
Data ownership, model governance, versioning and change control across every layer. Every prediction records the model version, the input snapshot and the configuration that produced it, so a decision made eighteen months ago can be reconstructed exactly — which is what an audit, or an incident investigation, actually requires.
Data in
- Model and data version metadata
- Ownership and stewardship assignments
- Approval and change records
Data out
- Reproducible decision records
- Compliance and audit packages
- Impact analysis for proposed changes
Technologies
- Model registry with immutable versions
- OpenLineage
- Data contracts

- Reproducible run snapshots
