 ### 灰度环境 FBA 定向闭环
 
+同一入口可显式添加 `--prepare-domestic-pda-h5 true`，仅允许单独指定 `phase5-root-fulfillment`：创建本轮客户和两箱根订单，经测量、分柜、订舱放舱和计划确认生成一箱待拣任务及箱唛后停止，不领取/拣货/完成任务、不进入海外链。报告标记 `fullAcceptance=false`、`PREPARED_NOT_VERIFIED`，`createdResources.phase5RootFulfillment.domesticPdaH5Fixture` 保存任务、柜次、计划、仓库、入仓来源及箱信息供 H5；成功只代表准备完成。样本保留，失败不自动重试或清理，默认不传该参数时继续完整链。
+

 `admin-test-env-acceptance.mjs --environment gray` 显式支持临时灰度环境，当前仅开放 `--modules phase5-root-fulfillment` 及自动展开的本轮客户资质 fixture。该链会通过正式 HTTP 新建隔离客户、两箱根订单及分柜子来源，推进国内测量、装柜、报关、人工船节点、海外收货、排车、出库和签收；不是默认全量验收。默认全量中包含 TEST 专用故障注入和未经灰度副作用核对的模块，因此 gray 拒绝省略模块、附加模块、批量订单和卸柜故障开关，也不会创建 TEST fault executor。`--f40-tax-mode TAX_REFUND` 覆盖退税文件确认链；真实邮件和供应商自动查询不在此闭环的完成声明中。
 
 明确的仓库外环境文件须配置 `ADMIN_GRAY_GATEWAY`（统一 HTTPS 源站，不带 `/api`）、`ADMIN_GRAY_USERNAME`、`ADMIN_GRAY_PASSWORD`、`ADMIN_GRAY_PDA_USERNAME`、`ADMIN_GRAY_PDA_PASSWORD`；可选 `ADMIN_GRAY_CUSTOMER_NAME`。gray 不读取 TEST Gateway、管理员或 PDA 凭据。F40 始终创建本轮客户，不需要传已有 merchant 账号。数据库只读取证使用 `JENKINS_URL`、`JENKINS_USER`、`JENKINS_API_TOKEN` 及 Jenkins 已登记的 production SSH/host/known-hosts/env 凭据，由 `gray-regression-evidence.mjs` 实现，不调用 TEST agent 或写业务 SQL。
