The known image checker validates that tests only pull images from approved sources (cluster payload, mirrored repos, internal registry) to ensure disconnected environment compatibility. Previously it only checked e2e-* namespaces, so images pulled by oc adm must-gather in openshift-must-gather-* namespaces were never validated. This gap allowed operator-discovered must-gather images (e.g. cnv-must-gather-rhel9 from registry.redhat.io) to be pulled without detection, which would break disconnected clusters and caused pathological ImagePullBackOff events on IPv6-only clusters where registry.redhat.io is unreachable.
