Side B fixes a real algorithmic correctness bug (bipartite Markov chain oscillation in rank centrality) with a principled derivation tied to the cited paper, plus targeted regression tests in both Rust and Clojure across multiple topologies. Side A mostly deletes a large, over-engineered autocomplete parser and its test suite in favor of a simpler paste-and-go textarea, which is a reasonable simplification but is primarily churn/removal rather than a substantive lasting improvement, and it also strips out a Playwright race-condition test without an equivalent replacement guarantee.
