  "summary": "On 4 September 2026, three hosted test assertions passed for changing a session’s model. A change was refused while the session was running, accepted while it was checkpointed, and used by the next request without resetting the request lineage. These tests used a simulated compatible provider. They covered compatible clients through the tested routing path; native clients for the other protocol were explicitly outside this result. Live continuation quality was not measured here.",
