What
When Claude Code runs underneath a supervising host, a new piece of state tracks whether that connection is live, set false on connect, close and stop and true once the host's capabilities arrive. Artifact auto-react is now treated as available only when both those capabilities and a live link are present. Outside a supervised session the check returns early and nothing changes.
