AppStoreUploadEvent class

One line of cux_ship appstore upload --json.

See PlayUploadEvent for the stream's shape, the absent-rather-than-null rule and why no line carries display; all three hold here. What is different is what this stream can say, and there is one difference:

There are no UploadEvent.progress lines, and no bytesSent field to carry one. App Store Connect has no endpoint that accepts a binary, so the transfer is xcrun altool --upload-package — a subprocess speaking a transport Apple documents nowhere, whose output this package captures whole. There is no per-chunk signal to report. The alternative would be a tick on a timer, and a timer turns at the same rate whether the socket is moving or dead: it would report a wedged upload as a healthy one, which is the failure this stream exists to make visible. A field that is null on every line ever emitted is a format lying about itself, so there is none.

What this stream has instead is UploadState.processing, which is where an Apple upload spends most of its wall clock: Apple takes 5–15 minutes to process a build, and naming that is worth more than a bar would have been — a percentage stuck at 100 for six minutes says nothing about whose wait it is.
