Above that, 0x00409770 services the caches through 0x00409720, asks 0x00408380 for one staged entry, and then either appends or rotates it in-place, while 0x00409830 repeats the same builder twice before publishing the add-train/news side. So the remaining blocker is not the train-side consumer strip; it is the placed-structure-side owner seam that makes those site-cache lanes and ready bits trustworthy for shellless runs.".to_string(),
