 # Changelog
 
+## 2026-04-13 - 13.17.1 - fix(monitoring)
+stop allocating route metrics to domains when no request data exists
+
+- Removes the equal-split fallback for shared routes in MetricsManager.
+- Sets the proportional share to zero when a route has no recorded requests, avoiding inflated per-domain connection and throughput totals.
+
 ## 2026-04-13 - 13.17.0 - feat(monitoring,network-ui,routes)
 add request-based domain activity metrics and split routes into user and system views
