Distinguish a cancelled start future from a started one Review feedback on #23016. `task_status._future.done()` does not mean the worker reported the run as started. The cancellation that reaches this handler also cancels the future `TaskGroup.start` is awaiting, so it is done on both paths, and the guard therefore fired for a run whose infrastructure was still being provisioned. Measured inside the cancelled frame: started, then cancelled done=True cancelled=False cancelled while provisioning done=True cancelled=True `started()` resolves the future with a result; a cancelled future never carried one. Test both ways round: with the extra clause removed, the new test crashes a run that had not started. The `except Exception` branch below is unaffected — an exception there does not cancel the future, so its `not done()` still means what it says.
