What
Watching an artifact reports differently depending on session type. A remote session holds a subscription on the artifact service that outlives the session and wakes the session with a new turn when the artifact is republished or a comment is sent to Claude, with no live updates streamed. Local sessions keep the live connection and its streaming updates. The choice is automatic.
