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

Side A introduces a full RPC batch architecture (rpc.rs, room/scope model, CLI Public/Private commands) that meaningfully restructures the API surface and adds real new capability (rooms, batched calls, scoped garden/forum access), backed by substantial test and integration updates. Side B is a narrower, cleaner refactor (identity/canonical_path split, dropping '@' sigils) that improves code hygiene but has smaller lasting architectural impact than A's broader system redesign, even though A's diff is messier and less polished in places (e.g. leftover unused variables, more surface area to maintain).
