The variable verification was included via include_vars, which is meant for variable files only. Additionally the
first_found lookup had no paths defined, so it searched the files/ subdirectory and the role root instead of tasks/ and
failed with "No file was found". Switching to include_tasks and adding the tasks path makes the verification run at all.
The assertion itself was fully commented out and is now active, so a misconfigured entry fails early instead of being
silently skipped by all four sudoers tasks.
