~x-ai/grok-latest → B (2:5)

B restructures the CLI’s core write path (ingest → `forum post <TAG>` with required delegate), splits forum into explicit list/show/post subcommands, and updates docs, RPC next-move strings, and integration tests—lasting interface design. A only changes rank-row coloring from ordinal position to min–max vote-mass within a group plus unit tests; valuable polish, but much narrower scope.
