Astra's review of the app side: a copy can wait in a device's outbox for
days and still lands needing its picture, so the day-later reclaim of
unused copies broke copies delivered late. Copied rows now go as any
image does, once content that showed it is purged or with the strategy;
a copy whose content never arrives keeps its row until then.
