~x-ai/grok-latest → B (3:2)

B fixes concrete test-infra bugs (Clojure `str/split` on "=" vs #"=", `getRequestBody` vs `getInputStream`, null-safe token/state handling, 302 response length) that had broken OAuth mocks and thus all Playwright auth E2E flows. A’s `display_path` href change is a real prod consistency fix and the 45-pair ranking assertion is stronger coverage, but it extends one feature path rather than restoring foundational auth testing across the suite.
