 ### 3. HTTPRoute pattern
 
-Every HTTPRoute needs two annotations for DNS and routing to work:
-
-```yaml
-annotations:
-  external-dns.alpha.kubernetes.io/hostname: <service>.local.mk-labs.cloud
-  external-dns.alpha.kubernetes.io/target: "10.1.71.90"
-```
-
-And a parentRef pointing at the platform Gateway:
+Always include all fields explicitly — Cilium defaults `group`, `kind`, `weight`,
+and `matches` at reconcile time, causing ArgoCD out-of-sync if omitted.
+
+Full HTTPRoute template:
 
 ```yaml
+apiVersion: gateway.networking.k8s.io/v1
+kind: HTTPRoute
+metadata:
+  name: <service>
+  namespace: <app-namespace>
+  annotations:
+    external-dns.alpha.kubernetes.io/hostname: <service>.local.mk-labs.cloud
+    external-dns.alpha.kubernetes.io/target: "10.1.71.90"
 spec:
   parentRefs:
-    - name: fastpass-gateway
+    - group: gateway.networking.k8s.io
+      kind: Gateway
+      name: fastpass-gateway
       namespace: gateway
       sectionName: https
+  hostnames:
+    - <service>.local.mk-labs.cloud
+  rules:
+    - matches:
+        - path:
+            type: PathPrefix
+            value: /
+      backendRefs:
+        - group: ""
+          kind: Service
+          name: <service>
+          port: <port>
+          weight: 1
 ```
