The only operational surface was /healthz and a fold-out roster inside the owner's own reading page. This gives the owner a page: two sections of facts on the same measured sheet, no cards. - admin.go holds every route that reaches past the acting Reader, listed once in adminRoutes() and wrapped in requireOwner at registration - a missing gate is visible in the route list rather than hidden inside a handler. A non-owner gets 404, the same answer revoke already gave. - Lane figures arrive through the LaneReporter seam, so the page reads the running poller rather than a table. newRouter converts a nil *Poller to a nil interface: a typed nil would make the page claim a poller exists. - The roster moves out of the reading page and gains the Sighting counters, the blocked verdict and Clear marks. Clearing restores a privilege, so it is a plain ghost button; --danger stays with revocation. - --patina is the page's one accent, held at the weight of the other action accents. Neither --ember (new chapter) nor --danger (destruction) is borrowed for system health.
