+# KNELKumaGlpiBridge
+
+Uptime Kuma -> GLPI incident bridge. Kuma webhook POSTs land on
+`/webhook`; DOWN opens a GLPI incident ticket (deduped per monitor),
+UP posts a recovery followup and solves the ticket with evidence.
+
+Deployed on pfv-k8s via flux (NodePort 30801). GLPI tokens come from a
+k8s Secret created imperatively — never in git.
