      "S251 11/11 PASS ile S250 production reader gate'ini endpoint commit holder-graph revalidation ve task-facing endpoint root-authority validation yollarındaki iki read-only snapshot'a taşıdı. İki snapshot mevcut local IRQ maskesi ve IPC transaction kilidi altında kalır; reader membership registry linearization, wake reservation, CNode purge veya sonraki scheduler mutasyonundan önce düşer. Coverage 8/111'den 10/111'e ilerledi; 101 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.",
