WHY IT NEEDS A POLICY

Why mittwald_cronjob_create needs a policy

Creating a cronjob is a Write operation: it adds a new scheduled task to the system. While cronjobs can execute arbitrary commands on a schedule, the act of creating the cronjob definition itself is a reversible write operation (it can be deleted). Severity is medium because a misconfigured or malicious cronjob could repeatedly execute harmful commands, but the creation itself is not immediately destructive.
