v4: /follow/playlists opens the followed playlists' feed, and a page's test opens it through the app's routes — the path was a 404 since the two views of the followed feed became pages: the route table held each feed tab as an exact path, /follow, so /follow/playlists fell to /:handle/*, which read "follow" as a category and "playlists" as a tab it hasn't. /music/follow/playlists, which goes through that route, worked. The tabs' routes now take what follows them (/${tab}/*), which Feed already reads and refuses when it names no view.

No test saw it because each page's test mounted the page on a route pattern of its own, a copy of App's, with stand-in pages where a redirect lands: Index's parsed the path itself, and passed on one the app doesn't serve. renderPage (src/test/render.tsx) now opens a URL through AppRoutes, which App.tsx exports for it, inside the real providers, and every page's test uses it: the page is the one the app routes that URL to, behind its guard, and a redirect is checked by the path it lands on. An entry may be a location, to arrive with the state a link hands over. Every page being loaded with its route, the first query after opening one waits. src/test/App.test.tsx tests the table itself: the paths that are a feed, those that are not found, those that send a guest to sign in and back, and those that send a signed-in user home.

The profile's test held /@ann/dumps/x to be a path the profile answers as not found, which only its own pattern made true: in the app it is a dump's page. It now asks for /@ann/dumps/x/y. The tests of the two guards still mount them around a stand-in child, being tests of the guard alone.
