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

Side B fixes a real design flaw (ranking collapsed to per-contributor comparisons, short-circuiting when only one contributor existed even with multiple commits) with a coherent refactor that ranks per-commit, rolls up scores, updates evidence pages, and adds targeted tests covering the new behavior. Side A is a substantial SSE-streaming feature addition for Reddit fetch UX with good logging, but it's more feature churn/plumbing than a structural correctness fix, and it also deletes some existing unit tests without clear justification.
