Add explicit CRD/API defaults to manifests that were causing ArgoCD's SSA dry-run to produce results different from live state: - HTTPRoutes: add group, kind, weight defaults to parentRefs/backendRefs - Kyverno ClusterPolicies: add skipBackgroundRequests, allowExistingViolations - Tetragon TracingPolicies: add return, maxData, resolve, returnCopy defaults - Gateway certificateRefs: add group="" default - Guacamole Gateway: add group="" to certificateRefs Add ignoreDifferences for resources that legitimately differ: - Cilium cert Secrets (auto-generated, data always differs) - Istio ValidatingWebhookConfiguration failurePolicy (istiod mutates) - Crowdsec LAPI Secrets (randomly generated) - ServiceMonitor/PodMonitor relabeling action defaults - StatefulSet volumeClaimTemplates apiVersion/kind defaults Persist argocd-cm ignoreDifferences config in ArgoCD Helm values.
