~x-ai/grok-latest → A (3:2)

A delivers product-critical integrity: fail-closed vote auth (no silent anon fallback), mock OAuth gated behind env, Secure cookies, and tighter return-to sanitization—plus durable pinned by rev. B is a real lasting path-identity fix (tilde root normalization so garden child/rank lookups hit storage keys) with strong tests, but it is narrower domain plumbing than A’s multi-bug security/auth hardening.
