/**
 * 探测 DMS 删除内容的**正确姿势**（OpenAPI 与 Apifox 对 delContentById 的参数都未文档化）。
 *
 * 背景：Step-0 用 `DELETE /content/delContentById?id=<uuid>` 得 code=-1，行未删。
 * 线索：OpenAPI 里另有 `POST /content/updateAudit`（修改内容状态），
 *       而 DMS 的 states 语义是 0草稿 1待审 2审完 3发布 4销毁 5退回
 *       —— “删除”很可能是把 state 改成 4，而不是物理删除。
 *
 * 本脚本会：造测试行 → 逐一试候选形态 → 校验行是否真的消失 → 清理残留。
 * 用法：node harness/tools/dms-delete-probe.mjs <DMS_TOKEN>
