Priority: ⬇️ Low Estimated code review effort: 2 (Simple) | ~15 minutes Change: Feature Merge Risk: ⚪ Minimal · up to The chart currently prevents the object-controller Deployment from rendering, so the OpenShift startup issue cannot affect a deployment from this change. No actionable merge-blocking risk remains. Security Architecture ReviewSecurity architecture risk: ⚪ Minimal · up to The existing activation guard prevents these resources from being installed and rejects explicit enablement. This PR therefore introduces no reachable controller, privilege expansion, or metrics exposure. Certificate ownership and controller handover still need resolution before future activation.

we may also want a tilt guard here as with operator-controller [ref]

Done. Added the Tilt guard around both liveness and readiness probes, matching operator-controller so debugging does not trigger probe failures. Helm lint, manifest generation, rendering checks with Tilt enabled and disabled, and make verify passed.

we always seem to pass the metrics bind address in operator-controller [ref] - should we do the same here as well? Otherwise, should we also guard the NetworkPolicy 8443 rule on certs being enabled?

The conditional metrics argument is intentional: cmd/object-controller/main.go rejects an explicit metrics-bind-address unless tls-cert and tls-key are also supplied, and disables the metrics server when neither certificate is provided. Passing :8443 unconditionally would therefore prevent startup without cert-manager or OpenShift serving certificates.
The NetworkPolicy rule permits connections to 8443 but does not create a listener; without certificates there is no metrics endpoint to access. Guarding that rule would make the policy more precise, but is not required to keep metrics disabled. I have retained the conditional argument and the existing policy for now.

but is it problematic to keep an NP that doesn't do anything - shouldn't we follow some kind of principle of least configuration/resources or something like that? Feels like we're creating cruft.

Agreed—the unused metrics ingress rule should be conditional. I’ve guarded it on cert-manager or OpenShift certificates being enabled. The NetworkPolicy remains because its egress allowance lets object-controller reach the Kubernetes API despite the namespace’s default-deny policy.

use Kubernetes expansion syntax, `$(LOG_VERBOSITY)`, and ensure `LOG_VERBOSITY`
is defined in the container environment or render a numeric value directly.

Prepare the deployment, certificates, service, network policy, disruption budget, metrics monitor, and values. The activation guard keeps generated installations unchanged until the reconciliation cutover.

Description
Prepare the OLMv1 Helm chart for deploying object-controller as a separate component when ClusterObjectSet reconciliation moves out of operator-controller.
All new resources use the existing
objectController.enabledactivation guard. It prevents rendering these resources and rejects explicit enablement until the deployment and reconciliation cutover, so this PR leaves generated installations unchanged and avoids starting a second ClusterObjectSet reconciler.Refs: OPRUN-4775
