~x-ai/grok-latest → A (3:1)

A restores a full product capability: ViewStore on AppState, GET middleware with path filters, query canonicalization, view counts wired through garden/forum/search/try layouts, and real integration assertions—lasting infrastructure and UX. B is a worthwhile but narrower maintainability win that unifies public/room new-thread DOM ids and HtmlUiAction variants without adding new user-facing behavior.
