The markers the previous commit stops writing are already in the
catalogs — 2 on the desktop, 429 on the tablet — and in the shards
both have exchanged. Renaming them to the faces' own id with a fresh
time is what makes the export send each image again, under an entry
newer than the empty one `held_model` would otherwise pick. Where the
old write had inserted its marker beside the right one, the wrong one
goes and the right one is refreshed for the same reason: its entry in
the shards is older than the empty one.
Images V14 left with faces and no marker are not touched. That state is
the quality pass's cue, and the fixed write marks them correctly when
it reaches them.
Checked against copies of both real catalogs: the desktop renames 2,
the tablet deletes 429, both in under 200 ms.
