Awarded for completing Suppression Governance: Expiry, Review and Audit and passing its exam, demonstrating the ability to distinguish a suppression from a false positive correction, apply the four honest suppression reasons with the evidence each requires, set expiry and approval authority by class, write a reasoning record that survives the author's departure, keep a bulk suppression reviewable, define re-review triggers, assemble the evidence an assessor asks for, and migrate an ungoverned suppression estate onto a governed one.
Certificates are designed to be checked, not just displayed.
The credential is valid for 12 months from issue. Its public page states the expiry date, and renewing means passing the current exam again — so the credential always reflects the current material.
