just to double-check, Created is used to mean InProgress rather than Succeeded?

[tombuildsstuff]

(minor, but could we also move this up, since the other keys are sorted alphabetically)

Yes, Created means InProgress which I have verified locally. The poller will stop with a Succeeded response:

also moved up.
