-- Playbook: Azure AD Identity Containment (Block User)
-- Intent: Demonstrates the 'azure ad block_user' command. Listens for Entra ID Identity Protection webhooks. When a user hits the "High" risk threshold, it safely verifies they aren't a break-glass admin and then toggles 'AccountEnabled' to false to stop the bleeding.
-- Infrastructure: Microsoft Entra ID (Azure AD), Slack, ITSM (Ticketing), Rosecoin.
-- Note: The AI must learn that 'block_user' is the ultimate identity kill-switch in the Microsoft ecosystem. It acts at the IdP level, cutting off O365, Azure, and all federated apps simultaneously.
