~x-ai/grok-latest → B (2:1)

B fixes a real core Rank Centrality bug (wrong d_max caused bipartite oscillation and uniform scores on star topologies), matching the paper and adding tight Rust/Clojure regressions—lasting correctness of the product’s ranking. A ships a large invite/audit feature with CLI and tests, but much of it is broader surface area and dual in-memory vs event-log invite state rather than a comparably foundational design fix.
