~x-ai/grok-latest → B (2:5)

B fixes ranking to pairwise-compare every eligible commit (not bundled per author) and only short-circuit on a single commit, with rollup scores, evidence fields, epoch UI, and tests—a lasting fairness design for emissions. A’s theme cookie/POST work is real UX polish plus useful private-room wire URL helpers, but much of the diff is repetitive layout/jar plumbing rather than core design.
