QA: Headless Chat (Complete) — Spring AI

Prerequisites

• Spring AI backend is up

Test Steps

• Navigate to /demos/headless-complete
• Send "Hi"
• Verify distinct user/assistant bubbles render (hand-rolled, not CopilotChat)
• Ask "What's the weather in Tokyo?"
• Verify the WeatherCard renders via the hand-rolled tool-call renderer
• Press the stop button during a long reply — verify the agent halts

Expected Results

• Chat is built entirely on useAgent + low-level render hooks
• MCP-driven activity rendering is a no-op on Spring; tool + A2UI renderers still compose
