This release was manually Accepted.
Reason: MicroShift conformance test regression caused by OCPBUGS-99914 (service-ca stuck ContainerCreating, blocking DNS/LVMS cert issuance). Fix exists but not yet in a build. Blocking jobs (microshift-ovn-conformance-parallel, microshift-ovn-conformance-serial) are the only blocking failures across 5 consecutive rejected payloads. Only 1 unrelated PR in payload (Azure CAPI CVE fix). Upgrade tests passing 10/10. — https://redhat-internal.slack.com/archives/C0AMHBXQW9F/p1787226817518049
