~x-ai/grok-latest → B (2:1)

B fixes a core Rank Centrality correctness bug (weight-sum d_max → degree-based d_max per Negahban–Oh–Shah), restoring proper stationary scores on star graphs instead of bipartite oscillation back to uniform ties—directly fixing the product’s ranking output, with targeted Rust and fixture-driven Clojure regressions. A is a large, solid identity feature (Reddit OAuth, multi-link UUID principals, private linked-providers UI, pending-weight batch fix), but it extends auth rather than repairing the central ranking math the project is built around.
