      "S250 11/11 PASS ile S249 production reader gate'ini complete task IPC lifecycle ve task-owned endpoint-object teardown yollarındaki iki read-only authority-graph preflight'ına taşıdı. İki preflight mevcut local IRQ maskesi ve IPC transaction kilidi altında kalır; reader membership preflight dönüşünde, sonraki CNode/wake-queue/registry/scheduler mutasyonundan önce düşer. Coverage 6/111'den 8/111'e ilerledi; 103 site unrouted kalır. Writer/context-switch-capable hiçbir site yeni kapsama alınmadı. Production exclusive wrapper hâlâ yoktur; S245 request non-consuming incelenir, alınmaz ve pending kalır.",
