-- Playbook: Rapid Ransomware Containment
-- Intent: Detects encryption velocity anomalies, immediately isolates the infected endpoint, and preserves forensic state via disk snapshot.
-- Infrastructure: AINA, EDR (CrowdStrike/Defender), AWS EC2, Rosecoin.
-- Note: This playbook demonstrates iterating over arrays in a kinetic block using the 'each' primitive.

-- 1. CONFIGURATION GOVERNORS
-- Define the maximum threshold for file modifications per second.
-- ============================================================================
⚙️ keep ENCRYPTION_VELOCITY_LIMIT = 50
⚙️ keep ISOLATION_MODE = "strict_network_quarantine"
⚙️ keep CRITICAL_TIER = ["prod-db", "prod-api", "vault-core"]

-- ============================================================================
-- 2. HELPER FUNCTIONS (Read-Only)
-- ============================================================================
⭕️ define assess_ransomware_confidence(file_operations, host_tier)
  -- Utilize AINA to evaluate if the file operations match known ransomware patterns (e.g., changing extensions to .lock)
  🧠 set ai_verdict = aina.analyze(file_operations, "ransomware_heuristics")
  
  -- If the host is in our critical tier, we escalate the confidence score automatically
  ⚠️ when host_tier in CRITICAL_TIER
    🔹 change ai_verdict.confidence = ai_verdict.confidence + 20
  🔴 end

  return ai_verdict

-- 3. THE ENTRY POINT (The Check Block)
-- ============================================================================
🔥 check RansomwareOutbreakDefense
  
  -- Trigger Gate: Monitor EDR telemetry for rapid file system modifications
  ⚠️ when file_modifications_per_sec > ENCRYPTION_VELOCITY_LIMIT
    
    🔹 set infected_host = event.hostname
    🔹 set suspicious_procs = event.active_processes
    🔹 set threat_assessment = assess_ransomware_confidence(event.file_ops, infected_host)

    -- Gate: Only execute kinetic containment if AI confidence is extremely high
    ⚠️ when threat_assessment.confidence > 95
      
      🚨 alert critical message "🦠 RANSOMWARE VELOCITY DETECTED ON {infected_host}"
      📡 notify teams channel "Incident Response" message "Initiating 400ms Subnet Isolation Protocol"

      -- 4. THE KINETIC ZONE (Action and Remediation)
      -- ============================================================================
      ⚡ do
        
        -- Action 1: Instantly sever the host from the network to prevent lateral spread
        ☁️ edr isolate host infected_host mode ISOLATION_MODE
        
        -- Action 2: Iterate through the malicious processes and terminate them
        -- The 'each' keyword loops through collections safely within the kinetic boundary
        ⭕️ each proc in suspicious_procs
          ☁️ edr kill process proc.pid on infected_host
        🔴 end
        
        -- Action 3: Trigger a cloud-native snapshot of the EC2 instance for post-mortem DFIR
