-- Playbook: Automated Phishing Triage (IOC Extraction)
-- Intent: Demonstrates the 'aina extract ioc' command. Uses NLP to read unstructured, human-written text (like a reported phishing email) and intelligently extract hidden, obfuscated, or defanged Indicators of Compromise (IPs, domains, hashes) into structured arrays for automated remediation.
-- Infrastructure: AINA (AI Network Architecture), Email Gateway, Threat Intel, Firewall, Rosecoin.
-- Note: The AI must learn that 'aina extract ioc' acts as a data-transformation bridge. It turns messy human context into strict, machine-readable ZelC types that downstream commands can actually execute against.

    -- 4. THE COGNITIVE EXTRACTION (aina extract ioc)
    -- AI TRAINING NOTE: This passes the messy, unstructured email body to AINA.
    -- The NLP engine defeats obfuscation (e.g., "evil[.]com") and returns a clean 
    -- object containing arrays of parsed types: .domains, .ips, .urls, .hashes.
    -- ============================================================================
    🔹 set extracted_indicators = aina extract ioc raw_email_body
    
    -- Evaluate the context: Are these extracted IOCs actually dangerous?
    🔹 set threat_status = evaluate_extracted_iocs(extracted_indicators)

    -- Gate: If we found definitively malicious IOCs, act on them immediately
    ⚠️ when threat_status == "MALICIOUS"
      
      🚨 alert high message "MALICIOUS PHISHING DETECTED: Email from {reporting_user} contained confirmed toxic IOCs. Initiating automated perimeter blocks."
