One journey across the whole path: an account writes readings in three domains and files a PDF, downloads its own record as the passphrase-sealed archive, an admin snapshots it from the backups console, and the snapshot is restored over an account that has since lost a reading and a dose and gained one the snapshot never saw. The assertions address what the documentation promises rather than what the implementation happens to do. The archive is checked byte by byte against the HLX1 header in src/lib/export/passphrase-archive.ts — magic, version, KDF id and the Argon2 cost the file carries — because "a file arrived" is equally true of plaintext JSON under a new extension. The restored reading and dose are checked by their ORIGINAL ids, because a restore that re-created them under fresh ones would have written a different record that reads the same. The reading created after the snapshot is asserted GONE: the runbook says the restore replaces the account's data tables, and replacing is not merging. Two refusing controls. A stored copy with one flipped ciphertext byte is refused with the route's decrypt failure and leaves the record untouched — the envelope is AES-256-GCM and its tag covers every byte, so the flip is caught before the transaction opens. A delegate holding whole-record READ inside the account gets the not-covered panel instead of the export card, never reaches the console, and is refused 403 by the list, the manual run and the restore, the last of them naming the real snapshot so the refusal cannot be mistaken for a missing row. Waiting is on the job's own evidence: the console's endpoint is polled until this account's stored copy is newer than the click, so nothing in the file guesses at a queue. The journey has its own account, its own delegate and its own cookie jars; only the reset between repetitions and the deliberate corruption reach Postgres directly, because a browser cannot express either. The backups console gains data-testid hooks and a data-backup-id on each row so the spec addresses controls rather than translated labels.
