~x-ai/grok-latest → B (2:3)

B removes a redundant ExpandNewThreadForm action, handler, toolbar POST, and tests, SSR-ing #new-thread-ui-slot on home like room pages so compose is one consistent path instead of collapsed-then-morph. A is a correct, tested filter for stickied/pinned Reddit children, but it is a narrow import tweak versus B’s lasting UI simplification and deleted surface area.
