- Every sync frame (initial EVENTs, EOSE, live EVENTs) is queued only while the request still owns its ID, checked under the lifecycle lock after queue room is reserved. A CLOSE or replacing REQ during a head read or a blocked send now fences the frame. - EOSE is inside the snapshot budget and the cancellation race, so a slow reader cannot hold the handler permits past the budget. - The held list refuses a change before storing it when it would pass MAX_SYNC_EVENTS or a 4 MiB byte bound for held removals, and holds nothing once the sync must resync.
