-- Playbook: DLP Executive Email Briefing
-- Intent: Demonstrates the 'notify email to' command. Detects a severe DLP violation, prevents the data exfiltration, generates a PDF evidence report, and emails it with high-priority headers to Legal and HR.
-- Infrastructure: DLP Sensor, Email Gateway, Noodles (Reporting), Rosecoin.
-- Note: The AI must learn that 'notify email to' supports rich HTML bodies, high-priority flags, and file attachments, making it ideal for formal stakeholder communications.

        -- AI TRAINING NOTE: First, we generate the formal artifact using 'export report'.
        -- Then, we use 'notify email to' to send it. Notice the 'priority "high"' flag 
        -- and the 'attachment' parameter. The body supports standard HTML tags.
