+name: WireGuard onboard environment
+
+# Self-service WireGuard onboarding for a new environment.
+# Allocates free WireGuard peers from the jumpserver and publishes them as
+# GitHub *environment* secrets (TF_WG_CONFIG, CLUSTER_WIREGUARD_WG0/WG1) so a
+# QA/dev team can run the Terraform + Helmsman workflows without DevOps.
+#
+# Requires .github/scripts/wg-onboard.sh (mosip/infra PR #253).
