Where the folder listing can't vouch for a name (non-ASCII names, a listing that is gone), each photo's sidecar names are asked of the disk, nine per photo, one photo after another. The batch's lookups now run 16 at a time; the loop that plans the photos takes each one's answer in order.
They use the same `at_once` as the probe checks, so the latency stand-in measured with the previous commit applies to them as well (16 at a time against one at a time); the lookups themselves were not timed on a share for this version.
