  "summary": "On 19 September 2026, a synthetic tenant used the production customer routes to create, checkpoint, stop and resume one session. Its memory-backed witness persisted and its counter continued; the completed run cleaned up its test resources. This used one image, one guest size and one resume, with synthetic paid status. It tested the checkpoint route’s orderly stop, not a hard machine kill. Two earlier aborted attempts leaked sessions and were recorded as an open account-deletion issue; the successful cleanup does not erase that limitation.",
