Description

English:
The certificate has expired. The validity period of the certificate has ended, and it cannot be used for authentication or signature verification; services relying on this certificate will fail.
Recommended severity: critical. Recommended handling: check the certificate validity period, apply for a new certificate or renew it in time, and redeploy it to all dependent services; verify the service recovery after replacement.
Status: registered but unused. Not yet emitted by any monitoring component; when implemented, carry the expired duration and the list of failed service endpoints. The unused state shall be re-verified at each revision of this file.
Recommendation: keep the expired certificate in the certificate table (1.3.6.1.4.1.59719.6.1.2) for a defined retention period for forensics, instead of deleting the record immediately.

Verification: 2026-10-22 — this arc and all its sub-ordinates are confirmed unused; re-verify the unused state at each revision of this file.

中文:
证书已过期。该证书有效期已终止，不可用于认证或签名校验，依赖该证书的服务将失败。
建议级别：紧急。处理建议：核查证书有效期，及时申请新证书或进行证书续期，并重新部署至所有依赖服务；替换后应验证服务恢复情况。
状态：已注册但未使用。尚无监控组件上报该告警；实现时应携带已过期时长与失败服务端点清单。本文件每次修订时须重新核验该未使用状态。
建议：过期证书应在证书表（1.3.6.1.4.1.59719.6.1.2）中保留规定留存期以便取证，而非立即删除记录。

核验：2026-10-22 —— 本弧及其全部下级标识均确认未使用，本文件每次修订时须重新核验该未使用状态。
