~x-ai/grok-latest → A (2:1)

A ships production deploy (Docker/Fly/CI), multi-repo roots, and a real audit/SSE/status/watch path with tests and emission-loop hardening—net new lasting capability. B is a worthwhile identity/path split and wire-contract cleanup (optional naked delegate, no reducer rewriting), but mostly reorganizes and ripples existing behavior rather than adding comparable operational surface.
