title: "S336 · Yield-context-save production writer guard integration",
summary:
"S336, save_user_context_for_yield içindeki tek mutable SCHEDULER yolunu IRQ-masked CPU0 sınırında S335 ve 44 production reader'ın kullandığı aynı S247 state word'e bağlar. Writer üyeliği koşullu current-task kontrolü ile user/SP/ELR/SPSR/x0–x29/LR snapshot'ını kapsar; writer IRQ restore'dan önce düşer ve current task yoksa tarihsel no-op korunur. Guarded writer 9/69, açık writer 60 ve provider authority 0'dır; S337 ayrı ve açıktır.",
evidence: [
"Focused yield-context-save writer-integration kapısı iki bağımsız seri koşuda 24/24 PASS verdi.",
"Aynı S247 state word üzerinde CPU0-only writer membership, non-CPU0 pre-commit rejection, reader→writer ve writer→reader exclusion, exact-once commit/error release ve S335→S336 token monotonluğu doğrulandı.",
"Production kaynak sırası IRQ guard → acquire_s336 writer → tek mutable alias → koşullu current-task user/SP/ELR/SPSR/x0–x29/LR snapshot → writer drop → IRQ restore olarak kilitlendi. Missing-current-task yolu tarihsel no-op kalır.",
"EL0 syscall caller IRQ-masked bağlamı korur; S336 writer snapshot sonunda bırakılır ve ayrı S334 yield_now writer'ına taşınmaz. Exact tarihsel S298 yield-context-save semantiği korunur; S337 save_user_context_for_ipc_block sibling yolu değiştirilmedi.",
"QEMU, RPi4, RPi5 ve RPi5+SMP AArch64 compile profilleri fresh ve izole target dizinlerinde 4/4 exit 0 verdi; zero-warning iddiası yoktur.",
"S238–S336 dependency matrisi iki bağımsız koşuda 100 grup / 1494/1494 PASS verdi.",
"Exact yedi tarihsel G8h assertion adı dışlanıp kayıtlı --test-threads=1 kabulü kullanıldığında tam workspace 298 sonuç grubu / 3319 PASS / 0 fail / 7 filtered verdi. Filtresiz frozen S96 identity reddi nedeniyle global workspace GREEN iddia edilmez.",
"make verify-qemu ortak regresyonu strict ELF W^X 31/31 ve S130–S154 kabul zinciriyle bir kez PASS verdi. Bu, board-rpi5-only S336 writer invocation veya fiziksel cihaz gözlemi değildir.",
"Yerel website 518/518 test ile PASS; lint, boş çıktılı TypeScript kontrolü ve 23/23 static route ayrıca geçti. S336 kaydı yereldir ve deployment yapılmadı.",
"S245 request ve S244 admission dokunulmadan kalır; production provider authority=0, whole-scheduler exclusion=false ve toplam 60 production writer açık kalır.",
