4.21.0-0.nightly-2026-11-04-230437

Manual Override Applied

This release was manually Accepted.


Reason: Operator explicitly accepts risk of incomplete blocking and upgrade verification, unresolved HyperShift setup and GCP node-count failures, and unverified PR diff; completed-job analysis found no definitive regression, but infrastructure-only causation is unproven. — https://redhat-internal.slack.com/archives/C0BLKELJMSA/p1793837361438779
