# Render Flow

Use this flow after `zhihu-hotlist` has already produced ordered hotlist rows.

1. Keep the upstream artifact as the source of truth:

```json
{
  "source": "https://www.zhihu.com/hot",
  "sheet_name": "知乎热榜",
  "columns": ["rank", "title", "heat"],
  "rows": [[1, "标题", "344万"]]
}
```

2. Call `screen_html_export` with at least:

```json
{
  "snapshot_id": "zhihu-hotlist-20260329",
  "generated_at_ms": 1774713600000,
  "rows": [[1, "标题", "344万"]]
}
```

3. Expect the tool result to include:

```json
{
  "output_path": "/abs/path/zhihu-hotlist-screen.html",
  "presentation": {
    "mode": "new_tab",
    "title": "知乎热榜主题分类分析大屏",
    "url": "file:///abs/path/zhihu-hotlist-screen.html",
    "open_in_new_tab": true
  }
}
```

4. Final delivery rules:

- The local `.html` path is the generated artifact.
- `presentation.url` is the browser-open target.
- Final wording should say the dashboard is ready for新标签页展示.
