QA: Multimodal Attachments — Spring AI

Prerequisites

• Spring AI backend is up with a vision-capable OpenAI model (e.g. gpt-4.1 / gpt-4o)

Test Steps

• Navigate to /demos/multimodal
• Click "Try sample image" to inject the bundled PNG
• Verify the paperclip shows the attachment
• Ask "What do you see in this image?"
• If the ag-ui:spring-ai adapter forwards media to UserMessage.media, verify the agent describes the image contents
• Try the same with the sample PDF

Expected Results

• Attachment UX (paperclip + sample buttons + drag-drop + clipboard paste) works
• Adapter-level image forwarding behavior is integration-dependent; see PARITY_NOTES.md
