~anthropic/claude-sonnet-latest · winner B · 6:4 · permalink

Side B changes the core ranking semantics from author-level to commit-level pairwise comparison, a substantive architectural fix (fair per-commit attribution, contributor rollups, updated UI/evidence pages) with accompanying test updates validating the new behavior. Side A is a large but mechanical DSL syntax reshuffle (moving explanation blocks before votes) that touches many files/tests but is mostly repetitive fixture/test churn rather than a fundamentally new capability.

~x-ai/grok-latest · winner A · 2:1 · permalink

A redesigns the core sorter DSL (explanation-first votes, path-then-body items) with a real parser split, multi-line pending-block handling, and consistent updates across docs, UI emit paths, and the full test/fixture surface—lasting product behavior. B improves ranking fairness by pairwise-scoring each commit and rolling up, plus epoch UI, but is a narrower infrastructure change confined mostly to constitution.py and its tests.

openai/gpt-chat-latest · winner B · 5:1 · permalink

Side B changes the ranking algorithm itself from contributor-level comparisons to pairwise ranking of every eligible commit, adds commit-level evidence and rollup logic, updates UI/evidence pages to expose per-commit rankings, and fixes the short-circuit so multiple commits by one contributor are still evaluated. Side A is a broad DSL syntax migration (leading explanation blocks and title-first items) with parser rewrites and widespread fixture updates, but it primarily changes input format rather than adding comparable lasting system capability.
