See the adjacent document's v0.9.1 mapping before using it as implementation guidance. Licensing boundaries ------------------- CopilotKit marketing-site images are not presumed to inherit the software repository license. C1 and C2 are files in the licensed GitHub repository. The Google website's license is not presumed to license the entire paper. No PDF, unrelated generated demo artwork, or complete third-party article is redistributed here. Original analytical SVGs elsewhere in this topic are separately authored diagrams, not altered copies of these source figures. Screen captures (quotation for commentary) ----------------------------------------- The following assets are screen captures of publicly reachable product, demo and research pages. They are included to describe and critique the claims and interfaces those pages present. Copyright stays with each owner; inclusion is not a license grant, an endorsement, or a compatibility certification. No credentials, personal data, customer identifiers or private screens appear in them. Browser chrome showing a local profile was cropped out before publication. S1: ../images/gemini-dynamic-view-screencast.gif Title: Generative UI in dynamic view - Van Gogh gallery example Author/project: Google. Copyright (c) Google. Source page: https://blog.google/products/gemini/gemini-3-gemini-app/ Source asset: Dynamic_View_Van_Gogh_1920x1080_1.mp4 (Google blog video) Captured: 2026-09-22 Processing: re-encoded to GIF at 8 fps and 680 px width from a 17.8 s, 1424x888 recording. Frames are not otherwise altered; no frames added. Notice retained from the original: "Sequences shortened and screen images simulated. Check responses. Compatibility and availability varies. 18+." License: no open license. Used as a short quotation for commentary. S2: ../images/ag-ui-dojo-backend-tool-rendering-screenshot.png Title: AG-UI Interactive Dojo - Backend Tool Rendering demo Author/project: AG-UI Protocol contributors and demo authors. Source: https://dojo.ag-ui.com/langgraph/feature/backend_tool_rendering Captured: 2026-09-22 Processing: cropped to remove browser chrome and the local browser profile indicator. No content changes inside the application area. License: public demo screen, no separate license grant located. Used as a quotation for commentary on the Controlled pattern. S3: ../images/copilotkit-product-overview-screenshot.png Title: "Any frontend. Any agent." product overview Author/project: CopilotKit. Copyright (c) CopilotKit. Source: https://www.copilotkit.ai/product Captured: 2026-09-22 Processing: proportional downscale to 1400 px width. No content changes. License: marketing-site content, no open license. Vendor product and ecosystem logos identify the claim under discussion, not an endorsement. S4: ../images/demo-generative-ui.mp4 Title: "Generative UI Specs" demo application walkthrough Author/project: demo application built with CopilotKit; author not stated on screen. No public distribution URL for this recording was confirmed. Captured: 2026-09-22 Processing: re-encoded to 1280 px width, 30 fps, audio removed, from a 33.5 s 3680x2160 60 fps recording. No frames added, removed or reordered. Content note: the demo compares Static GenUI, MCP Apps and A2UI in one app. All on-screen records are example data (example.com addresses, 555 phone numbers, explicitly fictional place names). License: no license grant located. Retained because it documents the three approaches this topic compares; remove on request of the author. Materials reviewed but not redistributed ---------------------------------------- "AG-UI and A2UI Explained" (CopilotKit, Google Docs PDF export) was read to summarize the vendor's own framing of AG-UI, A2UI, Open-JSON-UI and MCP-UI. The PDF itself is not committed. Its substantive claims were located in public documentation and are cited from there instead: https://docs.ag-ui.com/concepts/generative-ui-specs and https://www.copilotkit.ai/ag-ui-and-a2ui. Remaining claims were cross-checked against a2ui.org, docs.copilotkit.ai and modelcontextprotocol.io. The source recordings behind S1 and S4 are not committed at original size; only the reduced GIF and the re-encoded MP4 are published. A capture of the generativeui.github.io method overview was dropped because the same figure is already included as the CC BY-SA licensed original SVG (G1).
