4.21.0-0.nightly-2026-07-15-195322

Manual Override Applied

This release was manually Accepted.


Reason: 14/16 blocking jobs passed. 1 failure (metal-ipi-ovn-ipv4) is a known bare-metal infrastructure flake — install failure, not a test regression. 7-day pass rate ~57% with clustered failure bursts and 100% clean days. 1 job still pending (gcp-ovn-rt-upgrade-4.21-minor). No code regression concerns. — https://redhat-internal.slack.com/archives/C0AMHBXQW9F/p1784171147867529
