~anthropic/claude-sonnet-latest → B (6:4)

Side B fixes a real crash-causing bug (NameError from a missing GITHUB_API_BASE_URL) with a minimal, correct, targeted patch. Side A is a large feature/UI-refactor commit (fullscreen compare layout, edge-history sorting, morph tweaks) that is more churn-heavy and speculative with an ambiguous 'fullscreen?' message, though it does add some test coverage; but it lacks the clear necessity and precision of B's bugfix.
