 It requires a non-root Linux account, installed `visudo`, bubblewrap, permitted unprivileged user/PID namespaces, and an existing `/etc/sudoers.d`. It maps a disposable policy directory and does not invoke real sudo or write a live grant. Run it on a suitable Linux executor; namespace restrictions are a reported failure, not proof that the policy passed.
