The contents of notes and papers this device sealed whose file was taken out (removed_now: by this device, or read in another device’s record), each with that record’s writer and round (Sealed::removed); each is due once every device that counts read past that round (readers: a reader without notes in the folder read none, and holds it): its last use then counts as days ago, and blobs::sweep_after takes it out at once, with its care all the same: never a content used again or named lately, never one made fresh within days (on a phone under eDrive, which keeps every sealed file it brought, a content used again past that is made fresh, and sent there again). Nothing else needs it: a device taking such a file out keeps it as a copy among its earlier versions (history::keep_moved), and a device joining, or back after long, reads that it was taken out. Only when early: every device that counts says it keeps such a file so (blobs::KEEPING_MOVED); an earlier Sioul keeps it by reference, its content needed in the folder for history::SEALED_DAYS. Until 17 October 2026 such a content stayed two weeks more (90 days while an older Sioul counts, as it still does: days), as it does when not early. Forgotten once swept, or once current again.
