A Restore refused as busy now opens the same review again with Discard /
Restore, and a restore job whose leases did not drain hands its review back
(scope.review_kept) to the page that started it, which reopens it; every
other path that abandons a token after Restore sends its DELETE, so held
reviews can no longer lock restore out. The kept-review line says where the
review is, and a full review store says what to do (I1). applyPlan resolves
with its outcome and its job tracking now has failing-before proof (N5).
Also: the safety-backup toggle says what the policy does (D104, M2); the
restore picker has no type filter so safety backups can be chosen (M3);
"Export all prompts JSON" names what /export holds (N1); small snapshots
show KB (N3); the duplicated holding and save helpers are shared (N4); a
dismissal test covers Cancel, x, Escape, a replacing dialog and leaving (M1).

System > Backup & export replaces its hand-off with the concept's section on the
S8 backend: Back up downloads the verified copy and the status line shows only
what GET /backup/status reports (D103); Review restore stages a chosen file and
shows the server's review in the shared review dialog, Cancel discards the stage
and Restore runs the Database restore job, after which the open views reload
(D105); Export JSON plus the components and saved-pairs exports (D103); Import /
inspect opens the shared Import & inspect dialog; the safety-backup policy saves
through the Save row and scheduled backups offer Manual only (D104). Overview's
Backup status row reads the same status.
