~x-ai/grok-latest → B (1:3)

B rewrites the core domain from flat scope maps to a hierarchical GlobalTree/ItemId model (canonical URL paths, parent/child wiring, journal worker, UI breadcrumbs, vote/event replay), which permanently changes product behavior. A adds solid but auxiliary workspace tooling (offline.rs compile/scan + sorterc CLI) that validates DSL/JSONL without altering the runtime architecture.
