+  - ID: P
+    Severity: error
+    Description: |
+      A Route entity uses the `expressions`` router flavour, but the Data Plane node does not support `router_flavor = expressions``. The Control Plane refuses to sync the configuration.
+    Resolution: "Upgrade the Data Plane to version `3.6.0.0`` or later, or change the Route to a supported router flavour."
+    DocumentationURL: "/gateway-manager/version-compatibility/"
+  - ID: D
+    Severity: error
+    Description: |
+      The `ai-advanced-rate-limiting`` plugin configuration is incompatible across the 3.10 version boundary. Data Plane versions earlier than 3.10 cannot accept configurations generated by a Control Plane on version 3.10 or later, so the Control Plane refuses dispatch.
+    Resolution: "Upgrade the Data Plane to version `3.10.0.0`` or later, or update the plugin configuration to the supported schema for the target version."

+    Severity: error
+    Description: |
+      The Data Plane certificate has expired or the mTLS identity is invalid. The Control Plane blocks configuration delivery to avoid insecure communication and marks the node as Out of sync.
+    Resolution: "Renew the Data Plane certificate or verify the cluster_mtls settings, then restart the Data Plane."
+    DocumentationURL: "/gateway-manager/data-plane-reference/#out-of-sync"
+  - ID: P
+    Severity: error
+    Description: |
+      The Control Plane detects an unsupported custom plugin or a plugin version mismatch on the Data Plane. The Data Plane cannot safely apply the configuration, so the Control Plane refuses to send the payload.
+    Resolution: "Install the missing custom plugin or align plugin versions on the Data Plane, then retry configuration delivery."
