 VPN fabric dial telemetry records the last capacity-limited endpoint and
 transport, making stream saturation visible without poisoning endpoint health
 observations.
+The same dial telemetry now keeps bounded per-endpoint capacity-pressure
+counters, so operators can see whether stream saturation is occasional or
+concentrated on a specific QUIC carrier.
 Endpoint ranking treats `capacity_limited` observations as a soft pressure
 penalty instead of a hard recent failure, enabling load spreading without
 marking the carrier unhealthy.
