openai/gpt-chat-latest → B (5:1)

Side B adds a durable correctness constraint across the whole stack: it rejects invalid vote ratios (either side <1 or >100) in the DSL parser, UI handler, and reducer, preventing meaningless graph edges while adding regression tests for parser, reducer, integration, and browser behavior. Side A mainly replaces a complex autocomplete/transition-graph UI with a simpler paste-and-go flow, removing substantial functionality and tests while simplifying URL parsing, which is a product-direction change rather than a clear long-term correctness improvement.
