  与锁定态统一/可信代理(X-Forwarded-For)限流加固/会话版本失效机制/
  撤销即时传播/弱密钥拒绝启动/脱敏字节级重写(保签名契约)
- 业务逻辑: 裸 body 上传 panic/bootstrap 审计管线卡死/定价通配符优先级/
  全局工具可见性/调度器停机补跑/TOTP 挑战令牌消费顺序/熔断探针语义/
  >4MB 响应 token 计量/管理员重置密码作废会话 等
- 前端: 新 logo(语枢 AI 网关主题)/Provider 凭据异常警示/删除入口/
  后端错误消息透传/localStorage 敏感数据收敛
- 部署: CREDENTIAL_MASTER_KEY 持久化与弱值拒绝/Provider DELETE 接口/
