    summary:
      "S322 focused 15/15 PASS ile main.rs kaynak sırasındaki bir sonraki explicit mutable scheduler sınırını doğrular: run_qemu_s140_supervisor_recovery içindeki iki ipc_kernel_call_and_wait writer'ından daha önceki controlled pre-ACK-exit CALL. Nonzero controller, controller-owned normal Endpoint SEND authority, task-bound broker session/lease, strict EL0 controlled-exit supervisor RECV grant, immutable message ve linked cancelled reply writer'dan önce doğrulanır. Helper aynı IRQ/IPC transaction altında non-user caller SEND authority'sini, normal endpoint'i, linked reply'ı, optional receiver authority/deadline'ını ve tüm park kapasitesini yeniden doğrular; CALL publication/park ve optional delivery tek transaction içindedir. Controlled task exit cancelled reply'ı retire eder ve aynı controller'ı yalnız exact InvalidCapability ile resume eder; crashed supervisor reclaim, explicit broker recovery ve old-lease StaleLease sonucu daha sonraki S321 replacement CALL'den önce gelir. Writer authority yalnız model gate'inin exclusive lease'iyle mümkündür; reader lease'i writer'ı açmaz. main.rs 17 explicit writer / 12 previously audited / 4 remaining unaudited; S140 işlevi 2 / 0 ve tüm S140 aliasları source/model covered; 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.",
