 # Changelog
 
+## 2026-04-13 - 13.15.1 - fix(monitoring)
+improve domain activity aggregation for multi-domain and wildcard routes
+
+- map route metrics across all configured domains instead of only the first domain
+- resolve wildcard domain patterns against active protocol cache entries
+- distribute shared route traffic across matched domains and preserve fallback reporting for routes without domain configuration
+
 ## 2026-04-13 - 13.15.0 - feat(stats)
 add typed network stats response fields for bandwidth, domain activity, and protocol distribution
