 **Sync Safety Features**:
-- **Active users only**: Only syncs users with `ACTIVE` status in Okta,
-  automatically excluding suspended or deprovisioned accounts
-- **External collaborator protection**: Never removes outside collaborators
-  (non-org members), preserving contractors and partner access
-- **Outage protection**: Safety threshold (default 50%) prevents mass removal
-  if Okta/GitHub is experiencing issues. Sync aborts if removal ratio exceeds
-  threshold
-- **Orphaned user detection**: Identifies organization members not in any
-  Okta-synced teams and sends Slack notifications. Enabled by default when
-  sync is enabled.
+- Only syncs `ACTIVE` Okta users; never removes outside collaborators
+- Safety threshold (default 50%) aborts sync if too many removals detected
+- Orphaned user detection alerts when org members aren't in any synced teams
