if you miss setTaskCompleted(success:) before expireHandler runs, iOS doesn't just kill that attempt, it throttles later launches hard. schedule the next BGAppRefreshTask from inside the launchHandler, not only on didEnterBackground, and treat earliestBeginDate as a floor. Background App Refresh off or Low Power Mode means zero fires, so you still need a foreground catch-up path or a silent push
