The others’ contents of notes and papers that stopped being current in this exchange (theirs_now: replaced, taken out, or passed by a later change read in it), noted (Sealed::theirs); and those whose writer no longer counts by a sealed fact (Counted::departed: it left, you forgot it, another replaces it) swept, since that writer never sweeps them again (a phone dead for good), with the care blobs::sweep takes of this device’s own (blobs::sweep_after): unused unused_days since their last use here, never fresh in the folder (another device uses that content again, blobs::put), never one a current record names (a note’s, a change waiting, one the others named lately, one this device sealed itself, the texts’ media: texts_media), and nothing at all while the texts’ media are not known here, nor while a part whose files are sealed apart is not shared here (FILE_PARTS): the records of a part a device does not share are passed over, and a current paper with the same bytes as a departed device’s replaced note would go (review of 17 October 2026, L1). Each one swept is said for the server (Memory::taken). A device that counts sweeps them, each its own folder; two at once find it gone, and their sending a file gone (404) or changed (412).
