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

Side B implements a substantive behavioral change (per-commit rather than per-contributor ranking, with score rollups and UI updates) backed by new/updated tests across three test files, representing meaningful lasting functionality. Side A is a small, correct bugfix (reordering a guard check) with a single test update, which is valuable but far more limited in scope and impact than B's structural rework.
