    // Manual steps:
    // 1. Confirm cluster is healthy in admin portal → HA Status.
    // 2. Note which node is currently Active.
    // 3. Stop PBX service on the Active node (or power off the node).
    // 4. Measure time for cluster to promote Passive → Active.
    // 5. Verify admin portal becomes accessible on the new Active node within the defined RTO (e.g., < 30 s).
    // 6. Verify SIP registrations survive or re-register after failover.
    // 7. Record: failover time, re-registration count, any calls lost.
