System › Maintenance is native: the concept's notice and its Database and
Images & cache surfaces replace the hand-off.
- Integrity & relationship checks runs the health check; the report's
Review missing links reviews a fresh Missing-file links plan.
- Review plan shows the server's read-only plan (D100): scope, protected,
backup policy and media lines, the listed records, how long the review
holds and the backup box; Apply reviewed operation sends only its token
and opens the job in Activity. busy names the running job, plan-used links
the job that applied it, an expired or replaced review is reviewed again,
and a lost answer says Outcome not confirmed and points to Activity.
- Find duplicates starts the search; its view offers Review groups (D101):
ten groups at a time, Keep radios per copy, each keeper sent as
{group_id, root_index, path}; the dialog says History keeps the removed
paths in its run records.
- Thumbnail cache opens the thumbnail dialog; Metadata cache is disabled
with its reason while nothing is owned (D102, Q5).
- Activity descriptors for maintenance, duplicates and duplicate_cleanup.
- The legacy duplicates dialog's View Full names its source (?root=).
