// - 固定提示集(8 条,含反例"检查站点、下载器和媒体服务器是否正常"):按意图载入的 Skill、当前环境层的事实;
// - fake 模型按"合格模型"的路线调用能力:断言调用顺序、只读调用都成功、需要批准的被拒绝(不向用户要 ID:
//   download.inspect 的 ID 来自 download.list);
// - 汇报格式约束:合格汇报(只用工具结果里的数据写)通过 lintReport(无 UUID / 原始字节 / 内部字段,≤8 行,结论先行)。
// 真实模型的前后对比见 agent-prompt-eval.real.test.ts 与 docs/design/agent-prompt-eval.md。
