+Backup notification policy snapshot.
+
+Loads the latest committed, read-only backup notification policy. The policy
+defines success-noise suppression, failure/action-required escalation, and
+daily summary expectations; it never sends notifications, runs backups,
+starts restore drills, syncs offsite backups, writes credential markers,
+changes schedules, or writes workflows.
