FR-PLAT-AND-2, and a silent failure on both platforms. `dr_sync::scan`
stepped over a NotFound or PermissionDenied the way it does for a child
that vanished mid-walk -- correct for a child, wrong for the root, where
it ended the walk, returned Ok with nothing in it, and reported a
successful scan of a library that was no longer there.
A lost root is now its own error. The images under it are marked
Availability::Offline per FR-CAT-9 and no catalog row is deleted;
`library::persist` clears the mark per file as each one is listed again,
so a root that comes back needs no repair step.
Partly satisfied rather than closed, and the gap is worth stating.
The recovery half is real and reachable on Android today, because
`map_status` turns Nextcloud's 403 and 404 into it and Nextcloud is how
a phone actually gets a library in this build. The causes the
requirement names -- revocation, reinstall, a removed card -- are
properties of a persisted tree permission, and there is none: SAF does
not exist here, `SourceRef::Document` is constructed only in test
modules, and `LocalStorage` rejects the variant outright. When SAF
lands it becomes a third producer of this error and nothing above it
changes, which is why the discovery belongs in the connector.
