kyverno cli：bundleVerified，但策略失败？

Question

我正在尝试设置一项策略来阻止未经证明的图像。

这是我的代码：https://github.com/whoissqr/cg-test-keyless-sign

我的集群策略如下

apiVersion: kyverno.io/v1
kind: ClusterPolicy
metadata:
  name: check-image-keyless
spec:
  validationFailureAction: Enforce
  failurePolicy: Fail
  background: false
  webhookTimeoutSeconds: 30
  rules:
    - name: check-image-keyless
      match:
        any:
        - resources:
            kinds:
              - Pod
      verifyImages:
      - verifyDigest: false
        imageReferences:
        - "ghcr.io/whoissqr/cg-test-keyless-sign:latest"
        attestors:
        - entries:
          - keyless:
              subject: "https://github.com/whoissqr/cg-test-keyless-sign/.github/workflows/main.yml@refs/heads/main"
              issuer: "https://token.actions.githubusercontent.com"
              rekor:
                url: https://rekor.sigstore.dev

当我跑步时

 kubectl get clusterpolicies -o yaml | kyverno apply - --resource ./k3s/pod.yaml -v 5

，我得到了

policy check-image-keyless -> resource app/Pod/cg failed: 
1. check-image-keyless: unverified image ghcr.io/whoissqr/cg-test-keyless-sign:latest

“失败：1”到底是什么？

此外，通过 cosign 进行的 cosign 验证也已通过。
