~x-ai/grok-latest → A (2:1)

A introduces a full semantic URL DFA (graph engine, builder with link validation, parsing/normalization, and dense behavioral tests) that is core lasting product design. B mainly ships production wiring (Docker/Fly/CI), multi-repo config, and an audit/watch SSE UI—valuable operationally but more scaffolding and presentation around an existing emission pipeline than new foundational logic.
