Nightly sweep with two directions: attachments still unclaimed (pageId
null) after a 24 h grace period - claimed by no collab persist, page
upload, or import - are reclaimed (row, file, quota released); files on
the uploads volume without a database row (drift after a crashed
upload) are removed once older than the grace period. The grace period
protects the paste-then-insert window.
Deliberate deviation from the issue's content-reference idea, documented
in schema comment and operations.md: claimed attachments whose page
content no longer embeds them are NOT auto-deleted. The page attachments
panel lists claimed files as user-managed objects (inserting into the
document is optional there), so 'not embedded' is not 'unused' - an
auto-delete would destroy panel assets. Humans clean those up in the
panel or the pond file manager, which flags orphans already.
Attachment.deletedAt is removed by migration - deletion is hard
everywhere (sweep, purge, manual), there is no soft-delete state; the
never-true deletedAt:null filters in files/export queries went with it.
