  "summary": "On 31 August 2026, three hosted assertions passed for the termination guard. An ordinary termination request with unsaved work was refused and the session stayed alive, with safer choices explained. Explicit forced termination proceeded; a session with a saved checkpoint could be terminated normally. The protection was enforced by the service as well as the client. This guard protects unsaved work, not all destructive actions, and an explicit force request can still discard that work.",
