Shows a red warning banner at the top of the popup when no identity, email, username, or explicit mappings are configured. The status dot turns orange (instead of green) to indicate the extension is active but not protecting anything yet. Banner disappears as soon as the user saves their identity. Prevents users from thinking they're protected when nothing has been configured. https://claude.ai/code/session_01Dvgwe7XMoSxnWXkih8p1Cw
