~x-ai/grok-latest → B (2:5)

B removes scaffold demo-counter surface area and adds a lasting settlement worker (batched vote apply, event-log append, ranking cache warm/read path, read locks on ranking panel)—core production design. A correctly fixes test OAuth mocks (regex split, getRequestBody, null-safe state/token, handler try/catch) and login selectors, but value is confined to E2E test recovery rather than product architecture.
