~x-ai/grok-latest → B (2:1)

B tightens core path typing end-to-end (resolve_item → CanonicalItemUrl, typed pools/maps in validate/rank/pair RPC, Deref on href newtypes), removing repeated String↔CanonicalItemUrl glue and hardening the API model. A’s lasting piece is real but smaller: deleting leftover html/forum.rs so forum/ is the sole module root; most of the huge diff is relocated split-module code rather than new behavior.
