~anthropic/claude-sonnet-latest → A (65:35)

Side A is a substantial, coherent architectural change (RPC batch endpoint replacing dozens of REST routes, room/thread scoping refactor across CLI, server, reducer, events, and tests) that establishes a lasting new API design with broad test coverage updated to match. Side B is a smaller, more localized refactor (vote-compare UI morph behavior, ItemId normalization for Reddit imports, test helper extraction) that is useful but narrower in scope and impact than A's system-wide restructuring.
