Regression control
A model, prompt or connector update silently breaks a previously acceptable behaviour.
Requirement
Run risk-based regression tests before release and define which changes trigger targeted or full reassessment.
Expected evidence
- Release gate and regression history.
- Change-to-test impact matrix.
Proposed verification
- Select a release and trace its change, tests and approval.
- Confirm one failed critical test blocked promotion.
Limit
Unchanged tests may miss new failure modes introduced by a changed environment.
