~x-ai/grok-latest → B (2:5)

B lastingly reshapes the primary agent interface: scoped `forum list|show|post` replaces ambiguous `ingest`/`forum` shapes, requires `--delegate` on CLI posts, and updates GUIDE/DSL, RPC next-move strings, and integration tests in lockstep. A is a solid, tighter UX fix (auth POSTs return morphable fragments and poem JS handles non-empty bodies) but is a narrower surface change than B’s command-model redesign.
