    summary:
      "S310 focused 15/15 PASS ile main.rs içindeki kaynak sırasına göre en alttaki explicit mutable scheduler aliasını doğrular: qemu_s139_multi_event_caller normal exact-ACK yolundaki ipc_kernel_call_and_wait sınırı. Nonzero kernel caller, current-task CNode exact Endpoint generation/ENDPOINT_SEND authority ve linked reply-cap mint iki alias öncesinde doğrulanır. QueueFull probe dalı unpublished reply cleanup/result publication/task_exit ile normal yoldan terminal ayrılır. Normal yol exact broker lease ve message'i kurup endpoint/generation/reply/message zarfını helper'a forward eder; helper existing IRQ/IPC transaction altında non-user caller SEND authority, normal endpoint, linked reply, optional receiver authority/deadline ve ready/blocked capacity'yi yeniden doğrular, CALL'u publish/park eder, optional receiver'ı uyandırır, aynı kernel caller continuation'ını doğrular ve exact ACK'i reconstruct eder. Writer authority yalnız model gate'inin exclusive lease'iyle mümkündür; reader lease'i writer'ı açmaz. main.rs 17 explicit writer / 16 remaining unaudited, qemu_s139_multi_event_caller 2 / 1; 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.",
