[sylvesterkaczmarek]

The generated Ruby surface is internally consistent: the runtime models, websocket/server-event wrappers, RBI signatures, and RBS signatures all drop name together. That matters because leaving the field in only the static or wrapper layer would still make a valid terminal arguments event unusable for some consumers. item_id remains sufficient to recover the corresponding function-call identity.

[jbeckwith-oai]

Reviewed the exact head. The stable and beta Responses models, websocket unions, RBI, and RBS stay consistent with the corrected contract, while function-call item and Realtime names remain unchanged. CI is green.
