/**
 * ParseApi 单测 —— 真实数据源映射层
 *
 * 依据《API-契约.md》与《数据访问层设计.md》§三（映射只在此处发生）。
 *
 * 🔴 **本文件是回归重点**：开发期间此层踩过最多坑 ——
 *    ① 绑定表 `accessToken` 误填 Agent token（身份错）
 *    ② `host`/`channels`/`balance` 是**字符串形态 JSON**（存量 parseJsonLoose 教训）
 *    ③ 旧键 `remainRmb` 需归一为 `remainCny`
 *    ④ `fetchTasks` 云函数未实现时**必须抛错**，不得静默返回空数组
 *    ⑤ 错误文案取值顺序 `msg` → `mess` → `message`
 *
 * 手法：stub 全局 `fetch`，断言「请求形状」与「映射结果」两侧。
