~x-ai/grok-latest → A (3:1)

A is a precise, tested behavior fix: unranked siblings become one group each (aligned with the doc comment) instead of a single bulk group, with a regression test locking the layout. B is a diffuse “seed” dump (Dockerfile/fly.toml plus root-level event_log/views and a Clojure deps.edn) without evidence of integration or lasting design—more volume, less durable product substance.
