issue (blocking): CertProviderResourceGenerator (line 621) only generates Issuer/Certificate resources for deployments that serve webhooks. When an operator has owned APIService definitions backed by a deployment with no webhooks, no cert-manager resources will be created — yet this line annotates the APIService with cert-manager.io/inject-ca-from referencing that non-existent Certificate.
Result: cert-manager has nothing to inject, the APIService has no CA bundle, InsecureSkipTLSVerify is false, and API aggregation fails with TLS errors.
The fix is to also include APIService deployment names in CertProviderResourceGenerator:
deploymentsNeedingCerts := sets.Set[string]{}
for _, wh := range rv1.CSV.Spec.WebhookDefinitions {
deploymentsNeedingCerts.Insert(wh.DeploymentName)
}
for _, desc := range rv1.CSV.GetOwnedAPIServiceDescriptions() {
if desc.DeploymentName != "" {
deploymentsNeedingCerts.Insert(desc.DeploymentName)
}
}(The downstream openshift-service-ca path is unaffected since its AdditionalObjects() is a no-op.)

nitpick: This variable now holds ports from both webhooks and APIService definitions but the name still says webhook. Consider renaming to servicePortsByDeployment to match the updated comment on line 541.

thought (non-blocking): This iterates rv1.CSV.Spec.APIServiceDefinitions.Owned (raw, with potential duplicates) while all generators use rv1.CSV.GetOwnedAPIServiceDescriptions() (deduplicated, sorted). The choice seems intentionally fail-closed — validate every declared entry, even duplicates — but a brief comment noting why the raw field is used here (vs. the deduplicated method elsewhere) would help future readers.

The registry+v1 bundle renderer had no generator for APIService objects
from csv.spec.apiservicedefinitions.owned. This meant operators exposing
extension APIs via aggregation could not be migrated to OLMv1 (C3 hard
block in the migration tool).
Changes:
generators.go:
- BundleCSVAPIServiceGenerator: reads csv.spec.apiservicedefinitions.owned
and emits an APIService object for each entry (group=desc.Group,
version=desc.Version, GroupPriorityMinimum=2000, VersionPriority=15,
service reference to the certProvisioner's service in install namespace).
CA bundle injected via the CertificateProvider in opts.
- BundleCSVDeploymentGenerator: extended to inject apiservice-cert volume
and volume mounts into deployments that serve APIServices, matching the
existing webhook-cert injection path.
- BundleDeploymentServiceResourceGenerator: extended to create Services
for APIService-serving deployments (matching the webhook service path).
validators/validator.go:
- CheckAPIServiceDeploymentReferentialIntegrity: validates that every
owned APIService references a deployment that exists in the CSV install
spec, preventing misconfigured bundles from being installed.
certproviders/certmanager.go, openshift_serviceca.go:
- Added *apiregistrationv1.APIService case to InjectCABundle so the
cert-manager and openshift-service-ca providers annotate APIService
objects for CA bundle injection.
registryv1.go:
- Registered BundleCSVAPIServiceGenerator and
CheckAPIServiceDeploymentReferentialIntegrity.
Tests:
- generators_test.go: 4 tests for BundleCSVAPIServiceGenerator covering
zero-owned case, single APIService, multiple APIServices, and empty
DeploymentName fallback port.
- registryv1_test.go: enumeration tests updated.
go.mod/go.sum: upgraded k8s.io/kube-aggregator v0.36.2→v0.36.3.
Once this merges, the C3 hard block is removed from the migration tool
(operators with APIService definitions become Eligible with no override).

Summary
Adds the rendering infrastructure for APIService objects to the registry+v1 bundle renderer.
The implementation is complete but not yet activated —
BundleCSVAPIServiceGeneratorandCheckAPIServiceDeploymentReferentialIntegrityare not registered inResourceGeneratorsor
BundleValidatorpending end-to-end Boxcutter path validation. The code is retained asinfrastructure for a future release.
The OLMv0→OLMv1 migration tool (library-olm)
continues to hard-block operators with owned APIService definitions (C3) until this is fully
wired and confirmed working end-to-end.
