On Copilot Desktop 1.1.15 on Windows, using embedded agent runtime 1.0.83-5, an Autopilot coordinator can become stuck after its model turn finishes but the overall task never emits session.task_complete. Cross-session messages continue entering the pending queue, while repeated assistant.idle events occur without starting a new turn—a likely lost wake-up in the pendingMessagesChanged/deferred-idle queue-drain path. Restarting the session runtime and sending a direct prompt recovers it; changing the model appears to force that reinitialization.
