  "summary": "On 7 September 2026, six recorded assertions passed for account-level erasure on hosted infrastructure. Deleted-account checkpoints became unreadable after key destruction, including from the tested backup copy, while another account’s matching content remained restorable. Identity was removed from retained billing records. The rollout used team/test data; a cleanup error also removed the test canary’s chunks, with no reported customer impact. A fresh post-cleanup checkpoint subsequently resumed. This record does not establish that every backup or future deployment follows the same key-management conditions.",
