~anthropic/claude-sonnet-latest → B (6:4)

Side B is an actual executed refactor that splits a monolithic forum.rs into focused modules (nav.rs, ingest.rs, new_thread.rs, room_members.rs, access.rs) plus a small useful debugging script, improving real code organization while preserving behavior. Side A is purely a planning document plus a thin, incomplete RouteContext wrapper that mostly just forwards to ThreadNav—useful as a roadmap but contributes no functional improvement yet and risks becoming stale/deleted per its own text.
