~x-ai/grok-latest → A (7:1)

A replaces fragile GitHub API polling with deterministic multi-repo git mirroring, patch-id dedup, genesis/force-push/cherry-pick rules, and large unit/stateful/integration coverage—core protocol design for attribution. B adds a solid but narrower product feature (ephemeral invite links, RoomAudit, CLI, grant timeline merge) without comparable adversarial depth or foundational correctness work.
