~x-ai/grok-latest → B (1:3)

B fixes a real performance bottleneck (scan no longer full-replays every ingest through rank centrality), adds compile --ingest for targeted log replay, surfaces full DSL parse errors, and ships tests plus docs—lasting tooling value. A is solid UI polish (grouped click-to-copy CLI rows and JS-safety asserts) but is mostly presentation and call-site churn without comparable core capability.
