~x-ai/grok-latest → A (2:1)

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.
