QA: A2UI Fixed Schema — Spring AI

Prerequisites

• Spring AI backend is up with A2uiFixedSchemaController mounted at /a2ui-fixed-schema/run

Test Steps

• Navigate to /demos/a2ui-fixed-schema
• Click the "Find SFO → JFK" suggestion
• Verify a Flight Details card appears with SFO, arrow, JFK, UNITED badge, and a $289 price tag
• Click "Book flight"
• Verify the button transitions to "Booked ✓" (stateful ActionButton)

Expected Results

• Spring tool display_flight returns the fixed schema + data model
• A2UI middleware on runtime forwards it as ACTIVITY_SNAPSHOT events
• Catalog pins Title/Airport/Arrow/AirlineBadge/PriceTag/Button to React renderers
