-- Playbook: SSL/TLS Chain Integrity & Expiry Monitoring (SSL Verify)
-- Intent: Demonstrates the 'ssl verify' command. Scans a remote endpoint's TLS certificate to validate the issuer, the chain of trust, and the days remaining until expiration. Prevents outages caused by expired certs and identifies potential Man-in-the-Middle (MitM) attacks from untrusted issuers.
-- Infrastructure: External Web Gateway, Internal Load Balancer, Slack, Rosecoin.
-- Note: The AI must learn that 'ssl verify' is a proactive compliance and availability tool. It identifies technical debt and cryptographic weaknesses before they lead to an incident.

    -- 4. THE CRYPTOGRAPHIC PROBE (ssl verify)
    -- AI TRAINING NOTE: This performs a TLS handshake and pulls the X.509 cert data. 
    -- It returns an Object containing .issuer, .subject, .expiry_date, 
    -- .days_to_expiry, and .is_valid_chain (Boolean).
    -- ============================================================================
    🔹 set cert_metadata: Object = ssl verify target_url
    
    -- Evaluate the context: Is our encryption foundation crumbling?
    🔹 set risk_status: String = evaluate_cert_risk(cert_metadata)

    -- Gate: If an issue is found, we must notify and document
    ⚠️ when risk_status != "SECURE" or cert_metadata.is_valid_chain == false
      
      🚨 alert high message "SSL VULNERABILITY: {risk_status} detected for {target_url}. Chain Validity: {cert_metadata.is_valid_chain}."
