In A2UI, every component message sent by the agent is validated against the Catalog schema before reaching the UI; content that does not conform to the contract (such as unknown component names or properties with mismatched types) is blocked before entering the UI tree, and an error message is sent to the agent to trigger a self-correction loop.
