 Deployment workflows require the repository-level Actions variable `IB_GATEWAY_TARGETS_JSON`. It is a JSON object keyed by a non-sensitive target label (or a list whose entries include `name`). Every target supplies its own GCP project, Workload Identity provider, service account, VM location, and deployment settings. The repository has no default gateway or cloud account.
 
+Setting `maintenance_enabled=false` for a target pauses scheduled redeployment only; it does not disable the Gateway health and 2FA timers already installed on the VM. A scheduled workflow can succeed when every target was skipped, so its result does not verify the Gateway API, login, or account identity. Use the read-only diagnostics and separate account-level evidence; do not enable scheduled redeployment just to obtain a green workflow.

 部署 workflow 必须使用仓库级 Actions variable `IB_GATEWAY_TARGETS_JSON`。它是以非敏感目标标签为 key 的 JSON object（或每项包含 `name` 的 list）。每个目标自行提供 GCP project、Workload Identity provider、service account、VM 位置和部署参数；仓库中没有默认 gateway 或云账号。
 
+目标的 `maintenance_enabled=false` 仅暂停定时重新部署，不会关闭 VM 上已安装的 Gateway 健康与 2FA 定时器。定时 workflow 在所有目标被跳过时仍可能显示成功；该结果不代表 Gateway API、登录或账户身份已验证。需要运行只读诊断并另行核对账户级证据，不能为了获得绿色状态而重新启用定时部署。
