 Telegram is reserved for actionable alerts: `severity=info`, `Watchdog`, and
 `InfoInhibitor` remain visible in Prometheus but route to the null receiver.
 Warning and critical notifications are grouped for two minutes and rendered as
-Telegram HTML with escaped annotations and labelled graph/runbook links.
+Telegram HTML with escaped annotations and labelled alerts/runbook links.
+Notifications show at most three alerts, with each alert's escaped text limited
+to 500 characters. A single short Prometheus alerts link replaces repeated graph
+URLs; the full group remains visible there. Workload alerts show the affected
+DaemonSet, Deployment or StatefulSet rather than the kube-state-metrics pod
+which supplied the metric.
 
 Node Exporter keeps scraping the discovered node address, but rewrites the
 public `instance` label from Kubernetes discovery to `<node-name>:9100`. Grafana
