Cards for imported X-archive pieces showed no media even though the attachments were there — every archive image was saved pointing at a file that only ever existed on the import machine, so thumbnails silently failed to load and hid themselves. The library now rebuilds each image's real address on X's photo CDN from what was stored, at display time: archive cards render their photos again, with nothing rewritten behind your back.
Hundreds of imported archive pieces — mostly photo- and video-only tweets with no text to borrow — carried the literal placeholder title "Archived tweet". Titles are now derived from what the piece does have: the tweet's opening line when one exists, otherwise its media ("Photo tweet · Jun 2021"), always stamped with the original month so the card still tells you something. Fresh imports never write the bare placeholder in the first place.
