QA: Reasoning (Default Render) — Spring AI

Prerequisites

• Spring AI backend is up

Test Steps

• Navigate to /demos/reasoning-default-render
• Send a message
• Verify the page loads and chat responds normally

Expected Results

• Zero-config reasoning: no reasoningMessage slot is registered
• If REASONINGMESSAGE* events are emitted, the built-in CopilotChatReasoningMessage renders a collapsible card
• If not (current Spring AI adapter default), the chat behaves as a normal chat
