 "verdict": "Line-verified dead store: tmpfs_subr.c:1058 writes osize (loaded from aobj->size at :1055) back into aobj->size - a no-op; the surrounding cleanup (swap_pager_freespace/vm_object_page_remove over [nsize, osize)) shows the intent was aobj->size = nsize. Not userland-observable (no behavioral delta measurable from userspace; deallocate frees the whole object regardless), so no guest reproduction is possible - confirmed by inspection only. Latent trap for any future consumer trusting aobj->size after truncate; line identical in DragonFly master.",
