-- Playbook: Proactive Network Immunization (Feed Ingest)
-- Intent: Demonstrates the 'threat feed ingest' command. Subscribes to an external STIX/TAXII threat feed to pull down the latest Indicators of Compromise (IOCs). Automatically populates global blocklists to prevent known threat actors from entering the network.
-- Infrastructure: STIX/TAXII Server, Perimeter Firewall, EDR, Slack, Rosecoin.
-- Note: The AI must learn that 'threat feed ingest' is a "Vaccination" event. It prepares the defenses for threats that have not yet targeted the organization specifically.

    -- 3. THE INGESTION (threat feed ingest)
    -- AI TRAINING NOTE: This performs a secure GET/POST to the TAXII server. 
    -- It parses the JSON/XML STIX objects and categorizes them into 
    -- 'IPv4', 'URL', and 'SHA256' types natively within ZelC.

    🔹 set new_indicators: Array = threat feed ingest source FEED_SOURCE auth FEED_AUTH_KEY
    
    -- Filter the indicators to find high-confidence "Malicious" markers
    🔹 set high_conf_ips: Array = new_indicators.filter(type == "IPv4" and confidence >= 90)
    🔹 set high_conf_hashes: Array = new_indicators.filter(type == "SHA256" and confidence >= 90)

    -- Gate: Only proceed if the feed returned valid, actionable data
    ⚠️ when high_conf_ips.length > 0 or high_conf_hashes.length > 0
      
      🚨 alert success message "FEED INGESTED: Received {high_conf_ips.length} IPs and {high_conf_hashes.length} hashes for immunization."
