~x-ai/grok-latest → A (4:1)

A redesigns the core ownership-ranking path from author-bundled short-circuiting to true per-commit pairwise comparison with contributor rollup, evidence/UI surfaces, and targeted tests (same-author multi-commit, single-commit skip). B is a solid Reddit fetch worker (OAuth, rate limits, parsing) replacing a stub, but it is peripheral feature work plus .gitignore/todo noise, not a lasting change to the project's constitutive allocation logic.
