# Model Governance

> The activity of registering, evaluating and approving each model version before it is deployed.

Record: `architecture:model-governance`
Kind: activity
Layer: [Correctness Core](https://banes-lab.com/records/layer/correctness-core.md)
Severity: contextual
Scope: model lifecycle, model-backed system
Canonical: https://banes-lab.com/ontology#architecture-model-governance

Listed in [Architecture principles](https://banes-lab.com/api/records/architecture.md), after [Machine Learning Architecture](https://banes-lab.com/records/architecture/machine-learning-architecture.md) and before [Model Evaluation](https://banes-lab.com/records/architecture/model-evaluation.md).

## Repair

- Refactored by: Add Registry, Add Approval Workflow, Add Eval Gates
- Detected by: model without lineage/approval/eval
- Violated by: deploying unapproved/untracked models
- Measured by: governance coverage
- Enforced by: CI/CD model gates

## Requires

- [Model Registry](https://banes-lab.com/records/lexicon/model-registry.md)
- [Evaluation](https://banes-lab.com/records/lexicon/evaluation.md)
- [Approval Policy](https://banes-lab.com/records/lexicon/approval-policy.md)

## Reinforces

- [Compliance](https://banes-lab.com/records/architecture/compliance.md)
- [Model Safety](https://banes-lab.com/records/architecture/model-safety.md)

## Enables

- [Controlled Model Deployment](https://banes-lab.com/records/lexicon/controlled-model-deployment.md)
