@@ -465,6 +465,7 @@ Flow-scheduler snapshots now include a machine-readable pressure level
(`nominal`, `warning`, `critical`) and bounded reason list derived from drops,
route failures, route recovery, slow channels, bulk pressure, and adaptive
backpressure.
`mesh-live-smoke` reports the mixed-load scheduler pressure level and reasons.
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.
