      "S254 11/11 PASS ile S253 production reader gate'ini global current-task identity ve task page-table-root sorgularındaki iki read-only doğrudan scheduler okumasına taşıdı. Her iki sorgu yalnız Option<u64>/Option<PhysAddr> kopya değeri döndürür; scheduler referansı guard dışına çıkmaz ve reader membership fonksiyon dönüşünde düşer. Coverage 14/111'den 16/111'e ilerledi; 95 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.",
