kubernetes:4353.vb_47977da_9417 requires kubernetes-client-api >= 7.3.1-256.v788a_0b_787114 (confirmed via plugins.jenkins.io), but that plugin was never explicitly pinned in installPlugins — left to resolve on its own at image-build time, it landed on an older, incompatible version. Every build agent launch then crashed with NoSuchMethodError: ConfigBuilder.withMasterUrl(String) inside Reaper.preLaunch -> KubernetesCloud.connect -> KubernetesFactoryAdapter.createClient: pods provisioned fine at the Kubernetes API level, but the controller could never actually connect an agent to them, so every demo-go-app build hung forever at "Still waiting to schedule task".
