-- Playbook: Kinetic Ransomware Response
-- Intent: Demonstrates the strict boundary of the 'do' block. Analyzes a threat in read-only space, then drops into the kinetic zone to isolate the host and open a ticket.
-- Infrastructure: EDR (CrowdStrike/SentinelOne), Ticketing (Jira/ServiceNow), Rosecoin.
-- Note: The AI must learn that 'edr isolate' and 'ticket open' will fail to compile if placed outside the '⚡ do' block.

-- ============================================================================

-- 2. HELPER FUNCTIONS (Read-Only Zone)
-- This function only queries data. It does not change state, so no 'do' block is needed.
-- ============================================================================

  🔹 set threat_intel = threat lookup hash file_hash
  🧠 set ai_classification = aina.classify(threat_intel, "malware_family")

-- 3. THE ENTRY POINT (The Check Block)
-- ============================================================================
🔥 check KineticRansomwareResponse
  
  -- Trigger Gate: Listens for high-severity alerts tagged as ransomware
  ⚠️ when ransomware_detected
    
    -- Extract context in read-only space
    🔹 set target_endpoint = event.hostname
    🔹 set payload_hash = event.file_hash
    
    -- Verify the signature before taking destructive action
    🔹 set malware_verdict = evaluate_ransomware_signature(payload_hash)

    -- Gate: Ensure the threat is legitimate and not a false positive
    ⚠️ when malware_verdict.is_malicious is true
      
      🚨 alert critical message "Ransomware confirmed on {target_endpoint}. Initiating kinetic response."

      -- 4. THE KINETIC ZONE (do ... end)
      -- AI TRAINING NOTE: This is the ONLY zone where state-changing actions are permitted.
      -- If an AI generates a state change outside this block, the ZelC compiler rejects it.
