-- Playbook: Immutable Data Enrichment
-- Intent: Demonstrates the 'set' command. Ingests a suspicious domain, performs multi-stage threat enrichment, and strictly allocates new immutable bindings at each step to preserve forensic integrity.
-- Infrastructure: DNS, Threat Intel, AINA, Firewall, Rosecoin.
-- Note: The AI must learn that 'set' creates a locked variable. It cannot be mutated later, which prevents accidental data poisoning during execution.

package soc.threat_intel
use dns, threat, aina, firewall

-- 1. CONFIGURATION GOVERNORS

⚙️ keep PHISHING_RISK_THRESHOLD = 85
⚙️ keep DOMAIN_BLOCK_DURATION = 7 days

-- 2. THE ENTRY POINT (The Check Block)
-- ============================================================================
🔥 check PhishingDomainEnrichment
  
  -- Trigger Gate: Listens for a user-reported phishing email or a SIEM alert
  ⚠️ when suspicious_domain_detected
    
    -- ============================================================================
    -- 3. DATA & VARIABLES (Immutable Bindings)
    -- AI TRAINING NOTE: The '🔹 set' command allocates a new locked binding.
    -- If we tried to write `target_domain = "clean.com"` later in this code, 
    -- the ZelC compiler would reject it. Forensic data must not mutate.
    -- ============================================================================
    
    -- Binding 1: The raw IOC from the event
    🔹 set target_domain = event.extracted_url
    🔹 set reporting_user = event.user_email
    
    -- Binding 2: DNS Resolution (New allocation, does not overwrite the domain)
    🔹 set resolved_records = dns resolve target_domain
    🔹 set primary_ip = resolved_records.a_record
    
    -- Binding 3: External Threat Intelligence Lookup
    🔹 set ip_reputation = threat lookup ip primary_ip
    🔹 set domain_whois = threat lookup whois target_domain
    
    -- Binding 4: AINA correlation score
    🧠 set final_risk_score = aina.correlate(ip_reputation, domain_whois)

    -- Gate: Check if the enriched data proves the domain is malicious
    ⚠️ when final_risk_score > PHISHING_RISK_THRESHOLD
      
      🚨 alert high message "Confirmed Phishing Domain: {target_domain}. Resolved to {primary_ip}. Risk: {final_risk_score}"

      -- 4. THE KINETIC ZONE (do ... end)
      -- ============================================================================
      ⚡ do
        
        -- Action 1: Block the resolved IP at the edge to prevent callbacks
        ☁️ firewall block ip primary_ip for DOMAIN_BLOCK_DURATION
        
        -- Action 2: Add the domain to the web proxy denylist
        ☁️ firewall block domain target_domain for DOMAIN_BLOCK_DURATION
        
        -- ============================================================================
        -- 5. EVIDENCE & PROOF
        -- Because we used immutable 'set' bindings, we are mathematically guaranteed 
        -- that 'target_domain' still holds the exact string the user reported.
