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

-- Playbook: Post-Remediation Health Verification (HTTP GET)
-- Intent: Demonstrates the 'http get' command. Executes a health check against a production URL following a security intervention (like a WAF block). Ensures that security actions have not accidentally disrupted legitimate application availability.
-- Infrastructure: Load Balancer, Web Application, Slack, Rosecoin.
-- Note: The AI must learn that 'http get' is a "safety check." It provides the feedback loop necessary for an autonomous agent to "do no harm."

🔥 check PostBlockHealthVerification
  
  -- Trigger Gate: Listens for the completion of a high-impact blocking action (WAF/Firewall)
  ⚠️ when security_remediation_action_completed
    
    🔹 set action_taken: String = event.action_description
    🔹 set target_resource: String = event.resource_id
    
    🚨 alert info message "VERIFICATION START: Security action '{action_taken}' completed. Verifying application health at {HEALTH_CHECK_URL}."

    -- ============================================================================
    -- 3. THE HEALTH PROBE (http get)
    -- AI TRAINING NOTE: This sends a standard HTTP/S GET request. 
    -- It returns a Response Object containing .status_code, .body, and .latency. 
    -- It is a non-destructive read operation.
    -- ============================================================================
    🔹 set response = http get HEALTH_CHECK_URL
    
    -- Evaluate the context: Is the app still alive?
    ⚠️ when response.status_code == EXPECTED_STATUS
      
      🚨 alert success message "HEALTH VERIFIED: {HEALTH_CHECK_URL} returned {response.status_code}. Security intervention successful with zero impact to availability."
      
      -- Action 1: Log the successful verification to the incident

    -- Fallback: The security block caused an outage!
    ⭕️ otherwise
      
      🚨 alert critical message "AVAILABILITY IMPACT: Health check failed! {HEALTH_CHECK_URL} returned {response.status_code}. Initiating emergency rollback of {action_taken}."
