A2UI describes user interfaces as structured streamed data. It is a UI representation layer, distinct from tool protocols, agent-to-agent task exchange, and backend-to-application event protocols.
The catalog keeps the stable 0.9 line and the 1.0 candidate explicit. Renderer coverage, component vocabulary, transport, and extension behavior require revision-specific evidence.
