"""
The operator can tune how often the indexer's reconciliation backstop runs,
and how long it waits after a file's last write before hashing it.
Same shape as test_apps_enabled_policy.py / test_member_upload_policy.py:
changed by a signed operator instruction, stored on the node rather than the
hub. Unlike those two, there is also a *live* DirectoryIndexer object to
update — see test_set_scan_settings_updates_the_live_indexer below.
