Storing the resumed superstep's delta writes under their real task ids let a failed final checkpoint put leave the resumed task looking done: the next resume skipped it and lost its other writes. They keep their real task paths, so the order holds, but get the step-prefixed id. A resume addressed by checkpoint_id reruns tasks whose writes are already stored; the real id used to dedupe those, so their writes are now skipped instead.
