The Ephemerality Gap: Tackling Data Loss in AI-Generated UIs with an Open-Source Fix

I’m not a professional writer, and this is a relatively new problem space, so I’ll do my best to explain it. I think a lot of developers are overlooking this because Generative UI isn’t standard yet, but once you run into it, it becomes incredibly frustrating. For those unfamiliar, Generative UI (GenUI) usually means an AI agent sending a view definition (often JSON) to the frontend. The frontend renders components based on that definition and wires actions back to the agent. These views are inherently temporary. The moment you refresh the page or the agent regenerates the layout, the previous structure is often replaced. The upside is amazing. Interfaces in complex apps can adapt instantly to your workflow. Need three extra fields? No problem. Prefer the data displayed in a table instead of cards? Done. But this flexibility introduces a serious problem. The Ephemerality Gap I started calling this problem The Ephemerality Gap. Maybe someone has used the term before, but here’s how I de
