 # Star Chart Search Enhancer

-一个最小化的 Chrome MV3 实验插件，用来在巨量星图的达人详情页拦截页面自己的网络响应，并尝试提取两个“看后搜率”指标。
+一个最小化的 Chrome MV3 实验插件，用来增强巨量星图：
+
+- 达人详情页：保留原有的详情页控制台实验链路
+- 找达人列表页：在 `creator/market` 当前可见结果页中插入两列看后搜率

 ## 开发命令

@ -20,14 +23,31 @@ npm run build

 ## 手工验证

+### 详情页控制台实验
+
 1. 打开巨量星图的达人详情页
 2. 刷新页面一次，确保内容脚本和页面 hook 都能尽早注入
 3. 打开该页面的 DevTools Console
 4. 观察是否出现带有 `[star-chart-search-enhancer]` 前缀的日志
 5. 找到 `result` 日志，核对其中两个看后搜率是否与达人详情页右侧展示一致

+### 找达人列表页列增强
+
+1. 打开 `https://xingtu.cn/ad/creator/market`
+2. 等待当前列表页渲染完成
+3. 确认 `操作` 列前新增了两列：
+   `单视频看后搜率`
+   `个人视频看后搜率`
+4. 首次进入或翻页、筛选、搜索、排序变化后，新增列会先显示 `加载中...`
+5. 请求成功后，两列会显示对应达人的真实值
+6. 如果某行失败，两列都会显示 `加载失败`
+7. 点击任一失败单元格，会按整行重试该达人并重新进入 `加载中...`
+
 ## 当前范围

- 只支持巨量星图达人详情页
- 只输出到控制台，不改页面 UI
- 成功时输出结构化结果，超时也会输出一个明确失败结果
+- 阶段 1 同时支持：
+  - 巨量星图达人详情页控制台实验
+  - 巨量星图找达人 `creator/market` 当前可见结果页的两列增强
+- 列表页只处理当前可见结果页，不处理全部结果导出
+- 列表页使用内存缓存，同一标签页会话内会复用已成功加载的达人结果
+- 成功时输出结构化结果或渲染真实值，失败时会给出明确失败状态
