Fixed in https://github.com/badbundle/vault-app/pull/613 (merged as 2fdb0cc7).
While locked:
- The Auto-Backup page always opens with a header, including when it's locked, after a failed authentication, or with no password.
- In those states the header is fixed, in the Export page's style: "Auto-Backup" and one line on what it does.
Once unlocked: it becomes the live status header. That header is only built in the unlocked branch, so the folder name and error text can't show while locked.
Tests: the locked-state snapshots use a view model whose status names a folder and has an error, so any leak would change the reference images. There are new snapshots for the failed state and dark mode.
