-Hosted applications register once in the Stuffbox developer dashboard and send their assigned `clientId` instead of `selfHosted: true`. A first-time self-hosted installation receives a stable public client ID automatically; persist it for later connections.
+Stuffbox creates or reuses an identity for the exact callback automatically. Pass the returned `clientId` on later connections when available. The client ID is public routing information, not a secret.
