openai/gpt-chat-latest → B (5:1)

Side B fixes a correctness bug in the core Rank Centrality implementation by replacing the normalization divisor with the canonical degree-based d_max, preventing oscillation in star-topology graphs and producing the correct stationary distribution. It also adds focused Rust and end-to-end fixture regressions for star, inverse star, chain, and cycle cases, whereas Side A primarily removes a complex autocomplete/parser system in favor of a simpler paste-and-go UI and deletes substantial functionality rather than improving the underlying ranking logic.
