openai/gpt-chat-latest → A (10:1)

Side A implements a substantive correctness change by enforcing vote ratio bounds (both sides at least 1 and at most 100) across the DSL parser, UI POST handler, and reducer, preventing invalid graph edges and adding unit, integration, and browser regression tests. Side B is almost entirely terminology cleanup and renaming (e.g. canonical→item, function and comment renames, removal of a small helper) without materially changing project behavior.
