openai/gpt-chat-latest → B (3:2)

Side B enforces consistent vote-ratio validation across the DSL parser, UI handler, and reducer, preventing invalid zero-sided votes from creating graph inconsistencies and adding comprehensive regression and integration tests. Side A improves pair-selection heuristics by prioritizing attachment to established components and rank-adjacent refinement, but those are algorithmic refinements rather than the broad correctness and input-validation guarantees introduced by Side B.
