Record: `arch:model-drift-monitoring`
Kind: activity
Layer: [Correctness Core](https://banes-lab.com/records/layer/correctness-core.md)
Severity: mandatory for production models
Scope: model-backed system, model lifecycle, operations
Canonical: https://banes-lab.com/ontology#arch-model-drift-monitoring

## Repair

- Refactored by: Instrument Drift Monitoring
- Detected by: no ongoing evaluation of live model outputs
- Violated by: model quality assumed stable after deployment
- Measured by: drift in accuracy/quality metrics over time
- Enforced by: model governance review
