~x-ai/grok-latest → A (3:1)

A adds a real product capability (pool-scoped pairwise voting, optional pool query, constrained next-pair navigation, and a children vote entry point) wired through UI, form/RPC state, and suggest-next logic. B only restores E2E auth by patching test mocks (query split regex, getRequestBody, null-safe token/state, response length) and selector helpers—necessary maintenance, but narrower and test-only versus A’s lasting user-facing design.
