A Connect application represents the external product integrating Darwin. It owns redirect URIs, service accounts, linked-agent relationships, enrollment links, app-funded ephemeral goals, application balances, and webhook subscriptions. ## Boundaries An application does not own a user's Darwin account or agent. It receives a live, revocable grant after the user completes Sign in with Darwin or a hosted enrollment flow. Application credentials can manage only their own application resources. User-owned agent operations require a user OAuth token or another explicit linked-agent authorization. ## Lifecycle Create separate applications for development and production. Register exact HTTPS redirect URIs, rotate service-account credentials, and remove unused webhooks and grants. Deleting an application revokes its ability to act. It does not delete user-owned agents, goals, wallet history, deals, or outcomes. Register an application and prepare its production configuration.
