+Follow-up isolated built-worker verification used a disposable migrated D1
+database and provisioned owner: authenticated `GET /api/admin/operations?integrity=1`
+returned only time and two pass flags (both passed). After inserting one

+`sqlite: passed`, `foreignKeys: failed` and no row details. The actual owner
