Phase 1: Code-Level Verification

📝 Component Changes Verified

1.1 PackageServer Component - PDB Manifest Adapter

File: control-plane-operator/controllers/hostedcontrolplane/v2/olm/packageserver/component.go

func NewComponent() component.ControlPlaneComponent {
    return component.NewDeploymentComponent(ComponentName, &packageServer{}).
        WithAdaptFunction(adaptDeployment).
        WithManifestAdapter(
            "pdb.yaml",
            component.AdaptPodDisruptionBudget(),  // ← ADDED: Registers PDB for management cluster
        ).
        InjectKonnectivityContainer(...).
        Build()
}

Result: PDB manifest adapter registered ✅

1.2 CVO Deployment - PDB in Manifest Omit List

File: control-plane-operator/controllers/hostedcontrolplane/v2/cvo/deployment.go (line 151)

manifestsToOmit = []string{
    "0000_50_olm_00-pprof-config.yaml",
    ...
    "0000_50_olm_00-packageserver.pdb.yaml",  // ← ADDED: Prevents CVO from applying PDB to guest
    "0000_50_olm_07-olm-operator.deployment.yaml",
    ...
}

Result: PDB excluded from guest cluster manifests ✅

1.3 CVO Deployment - PDB in Resource Removal List

File: control-plane-operator/controllers/hostedcontrolplane/v2/cvo/deployment.go (lines 270, 278)

func resourcesToRemove(platformType hyperv1.PlatformType) []client.Object {
    switch platformType {
    case hyperv1.IBMCloudPlatform, hyperv1.PowerVSPlatform:
        return []client.Object{
            &policyv1.PodDisruptionBudget{
                ObjectMeta: metav1.ObjectMeta{
                    Name: "packageserver-pdb",
                    Namespace: "openshift-operator-lifecycle-manager"
                }  // ← ADDED: Removes PDB from guest cluster if present
            },
            ...
        }
    default:
        return []client.Object{
            &policyv1.PodDisruptionBudget{
                ObjectMeta: metav1.ObjectMeta{
                    Name: "packageserver-pdb",
                    Namespace: "openshift-operator-lifecycle-manager"
                }  // ← ADDED: Removes PDB from guest cluster if present
            },
            ...
        }
    }
}

Result: PDB explicitly removed from guest cluster (both IBMCloud and default platforms) ✅
