In the ensure_file() function, the "not_exist" code path checks whether $dir exists as a regular file. However, the intent is to verify that the target file ($file) does not exist, not the $dir. Testing $dir makes the existence check effectively useless -- it tests the wrong path and thus never catches the case where the file is unexpectedly present. Replace $dir with $file so the not_exist verification targets the correct path.
