FILE checks the archive folder and copies the packet inside the filing transaction. A failed check or copy rolls the filing back, so the packet stays in its previous stage; the person filing gets 503 archive_failed, and in its own transaction the server writes an archive.filing_blocked audit row and raises the critical archive_failed condition to Admin for that packet (who tried, folder, error). The next successful filing clears it. The archive-copy job now only catches up filings made while the archive was off. PLAN question 53, CHANGELOG, FEED and SECURITY updated.
