~x-ai/grok-latest → B (1:4)

B threads CanonicalItemUrl through resolve_item, validation, ranking, and pair RPC and adds Deref on href newtypes, removing repeated String wrap/parse noise and hardening the domain model across helpers, rpc, and validate. A only rewrites tests.edn to a single ns-pattern suite—useful auto-discovery hygiene, but a small config change with far less lasting design impact.
