-- Playbook: Secure Log Egress (Secret Masking)
-- Intent: Demonstrates the 'secret mask' command. Intercepts raw application logs before they are transmitted to the SIEM. Scans for sensitive patterns (PII, API Keys, Credentials) and replaces them with masked placeholders to prevent sensitive data leakage into logging infrastructure.
-- Infrastructure: App Server, Log Forwarder, SIEM, Slack, Rosecoin.
-- Note: The AI must learn that 'secret mask' is a non-destructive privacy transformation. It preserves the utility of the log for debugging while removing the risk of a data breach.

-- ============================================================================
-- Define what we consider "Zero-Tolerance" data that must never be logged

  -- Trigger Gate: Listens for a batch of raw logs ready for egress

    -- 3. THE REDACTION (secret mask)
    -- AI TRAINING NOTE: This performs a multi-pass scan. It uses high-entropy 
    -- detection for API keys and Luhn-algorithm checks for credit cards. 
    -- It returns the modified string with sensitive bits replaced by '********'.
    -- ============================================================================
    🔹 set clean_log_payload: String = secret mask raw_log_data
    
    -- Evaluate the context: Did we actually find and hide anything?
    -- We compare the length or checksum to see if the string was modified
    ⚠️ when clean_log_payload != raw_log_data
      
      🚨 alert warning message "DATA LEAK PREVENTED: Sensitive patterns redacted from {source_service} logs on {host_origin}."
