      "S249 11/11 PASS ile S248 production reader gate'ini task-owned endpoint grant ve notification grant yollarındaki iki exact capability_for_task authority snapshot'ına taşıdı. İki read mevcut local IRQ maskesi ve IPC transaction kilidi altında kalır; reader membership sonraki CNode/scheduler mutasyonundan önce lexical scope sonunda düşer. Coverage 4/111'den 6/111'e ilerledi; 105 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.",
