active_calls is permanently zero: state_store reads LeaseManager.get() while
RouterEngine constructs its own instance, so the router's leases are invisible
to the snapshot. And psutil.cpu_percent(interval=None) returns 0.0 on its first
call, so the dashboard shows CPU 0% at startup — a measured-looking number that
is not a measurement.
