~x-ai/grok-latest → A (2:1)

A fixes real correctness issues: vote attribution via out-of-band delegate_opt instead of stuffing WEB_BROWSER_AGENT into the DSL body, and refusing a bad all-items fallback when the sibling pool is < 2. B’s auth fragment/morph path is solid UX infrastructure, but it largely replaces working redirects rather than repairing broken behavior; A’s route rename/swap removal are lighter, yet the two logic fixes outweigh B’s polish.
