-When an AI agent is handed only your app's URL (for example, `https://yourapp.com`), it should be able to work out the rest on its own: which canisters your app comprises, what each one does, how to call them, how to query their data, and how to act as the signed-in user. No human supplying canister IDs, no bespoke integration.
