- useChat throttles streamed message updates (experimental_throttle, 150 ms), replacing the two hand-written 150 ms timers of the display_diagram and edit_diagram previews (94 lines less). The preview now only runs while the input streams; once it is complete the tool handler takes over, so a queued preview can no longer redraw an edit the handler rejected and rolled back. Measured on a streamed 60-cell diagram: 41 redraws at least 97 ms apart, before 37 with gaps down to 48 ms - The diagram check endpoint uses streamText with Output.object instead of the deprecated streamObject, and returns its fixed result as a plain text response; new route test - Import createGateway/gateway from ai and drop the direct @ai-sdk/gateway dependency - The per-request message structure logs only print with DEBUG_LLM_PAYLOAD=true - Remove an empty onFinish callback
