~x-ai/grok-latest → B (2:5)

B lands production authority (Fly Dockerfile/fly.toml, main-branch test-and-deploy CI), multi-repo/contributor roots, and a real auditable /watch+SSE/status pipeline with epoch-loop retry and ranking guards—core operational value. A’s lasting piece is the settlement worker plus cached read-path rankings and demo-counter removal, but that is a narrower sorter2 refactor versus making the constitution process deployable and observable.
