I still don’t know what was done or if there was a problem besides an exit code surprise, but I tested with a Remote volume size of 1 MB, and a roughly 40 MB source file which would backup to roughly 40 dblock.
On restore to an empty folder, it downloaded very little (as expected, because the source was still around). Clearing restore-path data again, and adding --no-local-blocks to stop source block grab downloaded:

I find its forecast of the number of files that need to be restored confusing. It seemingly hadn’t looked at restore-path the first time it forecast. Final forecast is not possible so early. Not sure about second time.
