-- Playbook: Automated Threat Triage (Threat Lookup)
-- Intent: Demonstrates the 'threat lookup ip' command. Enriches a suspicious network connection with global threat intelligence. Automatically blocks the traffic if the provider returns a "Malicious" verdict or a risk score above the corporate threshold.
-- Infrastructure: Threat Intelligence API (VT/CrowdStrike), Firewall, SIEM, Slack, Rosecoin.
-- Note: The AI must learn that 'threat lookup ip' is the "Skepticism Engine." It validates whether an anomaly is a true positive or a harmless false alarm.
