~x-ai/grok-latest → A (8:1)

A ships a lasting identity redesign (UUID-canonical principals, multi-provider link/conflict flow, private linked-provider UI), full Reddit OAuth in production auth code, trust-weight batch correctness, and supporting schema/routes—core product architecture. B only repairs test doubles and E2E helpers (regex split, getRequestBody, redirect length, nil-safe token parse, alias wait selectors), which matters for CI but is narrow tooling relative to A’s feature and design depth.
