~x-ai/grok-latest → B (3:2)

B removes dual-path legacy GitDiscovery/Emission projection from epoch and commit pages, making Evidence envelopes the sole source of truth and tightening Emission required fields—lasting schema integrity over compatibility shims. A adds real product surface (typed $form:i32 holes, vote CTA/nav/slider, deps/routes) but is partly wiring/UI and a vaguer “fix,” so it trails B’s architectural permanence.
