+/**
+ * TEST-only Gateway acceptance. Default is a local plan; --execute performs login,
+ * read-only queries and, with --probe-off-command, one deliberately rejected INVENTORY
+ * command after verifying OFF. Never collects, publishes, creates fixtures or changes config.
+ * Credentials: node --env-file=<explicit test-*.env> BEFORE this script; this script does not read credential files.
+ * Required env: CHONGCHONG_ENV=TEST, CHONGCHONG_ADMIN_API_BASE_URL (ends /api),
+ * CHONGCHONG_ADMIN_USERNAME/PASSWORD, CHONGCHONG_MERCHANT_USERNAME/PASSWORD,
+ * SELFOP_READONLY_USERNAME/PASSWORD (read permission only),
+ * SELFOP_DENIED_USERNAME/PASSWORD (platform without read or sync permission).
+ * Example: node --env-file=<test file> <script> --environment TEST --source-account <account>
+ *   --warehouse <configured warehouse> --other-warehouse <second configured warehouse>
+ *   --report <local json> --synthetic-fixture <fixture notes json> --execute --probe-off-command
+ * Reports contain case IDs, status, machine codes and request/trace IDs only; no payloads,
+ * URLs, credentials or customer identifiers. Partial/missing evidence is BLOCKED (exit 2).
+ * Re-run reads current state and uses a fresh rejection request key. No deletion or SQL.
+ * Register this service-local entry in the maintained script index before release.

 # 后端脚本管理与全量 HTTP 验收索引
 
+`../lastleg-service/scripts/selfoperated-test-env-acceptance.mjs`：自营统计 TEST Gateway 验收，默认仅输出计划；显式 `--execute --environment TEST --source-account <账号键> --warehouse <仓库编码> --other-warehouse <第二仓> --report <报告路径>` 才登录并查询。凭据由运行者通过脚本之前的 `node --env-file=<明确TEST文件>` 注入，需平台、只读平台、无权限平台及客户身份。`--probe-off-command` 仅在确认 OFF 后提交预期被拒绝的命令并核对无新增任务；不采集、发布、造数或写 SQL。`--synthetic-fixture <审核后的说明文件>` 验证合成样本，不能证明真实来源覆盖。报告脱敏记录各项结果及请求标识；失败保留报告，重跑使用新报告路径并重新登录，结束退出自身会话，不清理业务样本。离线合同为同目录 `selfoperated-test-env-acceptance.test.mjs`。

 `db/return-consolidated-incremental-20261012.sql`：10月10日/12日退货、签收、清点、换标与按件出库增量汇总，显式 `USE baiyue_lastleg`，MySQL 8.0.16+ 已有业务库可重复执行。本轮补齐签收原包装、尺寸重量来源及库存箱原包装三个字段；逐列判断存在性，不回填签收/清点事实，不改库存数量。连接实例及凭据由执行者明确指定，整份执行、遇错停止；保留执行错误，修复后可重跑，末尾输出字段、索引与约束供核对。托盘重量、体积汇总是应用逻辑，不新增资源库字段；不自动执行到测试或生产环境。
 
 `procurement-sample-test-env.mjs` 是采购样品正常全链路 TEST 专项入口，默认或 `--plan` 零网络。真实执行使用 `node --env-file="<授权目录>/test-acceptance.env" scripts/procurement-sample-test-env.mjs --execute --environment TEST --run-id <唯一短批次> --warehouse-id <已核对有效海外收货仓>`。只允许当前 TEST 工作区及指定配置；由正式 API 创建独立客户并完成资质，人工充值10元，上传凭证/面单，调用内部 `procurement-sample-fulfillment.mjs` 完成两箱正常履约。充值、文件和采购请求前落盘，结果未知停写；报告独占 `reports/procurement-sample-<批次>/report.json`，不覆盖旧报告，不自动重跑，不执行 SQL/部署/删除。结束退出自身平台与客户会话，保留样本。通过只表示该正常路径，不替代异常、退款、权限、真实页面和请求量验收。离线入口合同为 `procurement-sample-test-env.test.mjs`；内部模块安全合同见模块索引。
