新增 WireGuard 全互联、三 server embedded-etcd K3s、CloudNativePG 双实例、Barman OSS 备份、双 NGINX、Kubernetes Secret/RBAC 与本地旧文件按严格 24 小时清理。 新增维护窗口数据迁移、digest 固定滚动发布、应用回滚、跨节点文件 E2E、节点和数据库故障演练、CNPG 恢复与 etcd 快照验收脚本；洛杉矶仅作为带 NoSchedule 污点的仲裁节点。 所有生产 Secret 只在执行时从 0600 本地环境和旧生产容器导入，仓库不保存凭据；公网入口保持人工 DNS 故障切换边界。 验证：bash -n、ShellCheck、kubectl kustomize、Node 语法检查、Secret 扫描、OSS put/head/delete 实测。
