/**
 * Step-0：切换前端到 DMS 之前的**小样本实测**。
 *
 * 为什么需要它：DMS 的 content 读写接口在文档里全是「📄 未实测」
 * （参数来自 SKILL.md/Apifox，OpenAPI 里是 @RequestBody 抓不到），
 * 而前端的 upsert 依赖三件没被证实的事：
 *   ① addContent 是否要求 c_id（模型里 must=true）→ 若强校验，整个方案要改
 *   ② addContent 返回体里有没有记录 uuid（有则省掉一次反查）
 *   ③ timestamp 写入格式、states 默认值、长文本往返
 *
 * 怎么跑（在项目根目录；token 不落盘，从参数读）：
 *   node harness/tools/dms-step0-verify.mjs <DMS_TOKEN>
 *
 * 脚本会自行清理它写入的测试数据（session_id/record_id 以 step0_ 开头）。
