finished-marker in the cut copy: 1  -> F refuses to swap
D: whole copy marker: 1  cut copy marker: 0  -> D refuses to load

10:04:55 NOTE: the attempt above killed the docker CLIENT (rc 137) while the copy CONTAINER ran on and finished — so nothing was cut and the marker was written. Redo: kill the copy CONTAINER itself mid-copy.
