trust_drift previously fired alerts forever for playbooks stuck below the 0.2 threshold. With user authorization for governance-class auto-fixes, check_trust_drift now retires playbooks that have been unused for 30+ days (or never used and created 30+ days ago) by flipping status to 'deprecated' before alerting. Alerts now report drifted_count, auto_deprecated_count, and the kept playbook_ids that still need human review (those in their 30d trial window). Existing alert noise from the four currently-drifted playbooks should drop to whatever fraction is genuinely in trial. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
