    summary:
      "S314 focused 15/15 PASS ile main.rs içindeki kaynak sırasına göre S313 first-signal Wake aliasından hemen önceki explicit mutable scheduler sınırını doğrular: run_qemu_s147_notification_lifecycle içindeki controller owner-lifecycle teardown sonrasındaki stale notification_signal writer'ı. Nonzero controller task, controller-owned exact iki Notification root/WAIT grant, iki strict waiter'ın deadline active/registered=2 admission'ı ve exact waiter/generation/mask snapshot'ları writer'dan önce doğrulanır. Revoke grant exact-once kaldırılır, stale revoke reddedilir ve ilk S147 aliası revoke root id/generation/0x8 için yalnız Coalesced pending=0x8 kabul eder. teardown_task_ipc_lifecycle(controller_task) exact owned_notifications=2, revoked_notification_grants=1, cancelled_notification_waiters=1 ve woken_notification_waiters=1 sonucu üretir; ardından owner_close root id/generation/0x2 exact forward edilir ve yalnız InvalidCapability kabul edilir. Lifecycle helper IRQ/IPC transaction altında owner notification object'lerini ve owner CNode notification authority'lerini kaldırır. notification_signal helper nonzero current signaler ve canlı NOTIFICATION_SIGNAL authority kapısını deadline/registry/blocked/wake-capacity/Ready mutasyonundan önce uygular. Writer authority yalnız model gate'inin exclusive lease'iyle mümkündür; reader lease'i writer'ı açmaz. main.rs 17 explicit writer / 4 previously audited / 12 remaining unaudited; S147 işlevi 2 explicit / 1 remaining; production inventory 113 direct / 44 immutable guarded / 69 open writer olarak değişmez ve production exclusive wrapper, provider authority, whole-scheduler exclusion veya scheduler mutation üretilmez.",
