4.21.0-0.nightly-2026-08-13-095317

Manual Override Applied

This release was manually Accepted.


Reason: Single blocking failure is a known rare CRDValidationRatcheting cleanup timeout flake (99.86% Sippy pass rate). Zero code PRs in payload — only image rebuilds. Different failure modes across retries confirm flakiness. No recommended reverts from AI payload analysis. — https://redhat-internal.slack.com/archives/C0AMHBXQW9F/p1786654958395119
