      "S255 11/11 PASS ile S254 production reader gate'ini current-vruntime ve minimum-vruntime sorgularındaki iki read-only doğrudan scheduler okumasına taşıdı. Her iki sorgu yalnız u64 kopya değeri döndürür; scheduler referansı guard dışına çıkmaz ve reader membership fonksiyon dönüşünde düşer. Coverage 16/111'den 18/111'e ilerledi; 93 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.",
