 * Release class EnforceRelease asks, so the sidebar cannot offer a link the
 * server would answer with 404. A page rendered before the prop exists (or a
 * test that does not share it) treats everything as visible, which fails open
 * in the safe direction: the route still refuses, so nothing is exposed.
