/**
 * 验证写 DMS 时**到底发了哪些字段**（不需要 token，也不碰真实 DMS）。
 *
 * 为什么要单独测这个：用户明确要求 —— **「我的需求是传 title，不要传类似于 summary
 * 的多余的字段」**。字段多发/少发是很容易在后续改动里被"顺手"改掉的，
 * 而且它不像业务逻辑那样有直观的行为反馈，所以直接把请求体抓下来断言。
 *
 * 做法：把 `globalThis.fetch` 打桩，捕获模块真实发出的 form body，
 * 解析出 `content` 的键集合，断言「不多不少」。
 *
 * 怎么跑（在项目根目录）：
 *   npx esbuild harness/tools/_entry-dms.ts --bundle --format=esm \
 *     --outfile=harness/tools/_dms.mjs --alias:@=./src --define:import.meta.env='{}'
 *   node harness/tools/verify-dms-payload-fields.mjs
