End a Live Activity

Use priority: "high" for user-visible milestones (APNs 10), bounded to 4 per rolling minute and 20 per rolling hour per activity. Excess requests use APNs 5 with priorityReason: "budget_exhausted". Granted milestones remain queue barriers. Default routine updates use APNs 5. These are Notify admission limits, not Apple's unpublished device budget; iOS may still delay or skip states. Updates are accepted durably before an iOS update token is registered, and transient provider rejection remains queued for retry. queued counts pending device operations separately from accepted provider requests and permanent failures. Pending operations expire at the original activity deadline. Suggested visible-character budgets, not guaranteed fit or API hard limits: proportional glyphs, device width and accessibility text size change fit. 0 means hidden. Expanded and Lock Screen subtitle replaces status on line 2; compact and small banners retain status. Omitted subtitle uses status. Overflow shares the two-line detail area with explicit detail. Compact percentage takes precedence over status when progress is supplied; terminal shows percentage or its prompt icon and never status. Expanded budgets (title/line 2/detail): standard 32/36/100; ring 32/30/80; hero 24/36/100; terminal 36/40/100; steps 32/36/100. Compact title/subtitle/detail are hidden; status budget is 8 without progress, except terminal 0.
