//! **P2 E4：下载沙箱 + MOTW 端到端集成**（`#[ignore]`，本机/打包 chrome）。
|
||||
//!
|
||||
//! 验证：
|
||||
//! 1. **下载落隔离 workspace**：navigate fixture（含 `download` 属性链接）→ observe → 取链接 ref
|
||||
//! → `act(Click)` → 文件落进 per-pet workspace 的 `downloads/` 子目录（**非用户 Downloads**）+
|
||||
//! size>0。`allowAndName` 下文件名是下载 GUID。
|
||||
//! 2. **Win MOTW**：下载完成后该文件有 `Zone.Identifier` ADS 且含 `ZoneId=3`（`std::fs::read` 那个
|
||||
//! ADS 路径校验）。mac/linux 跳过 MOTW 断言（write_motw 空实现，登记在 PLATFORM-VERIFICATION.md）。
|
||||
//!
|
||||
//! 可执行 denylist 红线**拒绝判定**走纯逻辑单测（`download::tests`，不需真浏览器）——这里只验「良性
|
||||
//! 文件真落盘 + MOTW 标记」的端到端链路。
|
||||
//!
|
||||
//! 手动跑（本机 Windows 有系统 Chrome）：
|
||||
//! set NOMIFUN_CHROME_BINARY=C:\Program Files\Google\Chrome\Application\chrome.exe
|
||||
//! cargo nextest run -p nomi-browser-engine --run-ignored all -E 'test(download_) | test(motw)'
|
||||
//! 跑完核对任务管理器无残留 chrome（Builder kill_on_drop 应自动清）。
