# Star Chart Search Enhancer

Chrome MV3 extension for the Xingtu creator market page.

## Development

```bash
npm install
npm test
npm run build
```

## Load The Extension

1. Run `npm run build`
2. Open `chrome://extensions`
3. Enable developer mode
4. Choose `Load unpacked`
5. Select the `dist/` directory

## Current Scope

- Adds two after-search-rate columns to the Xingtu market list
- Hydrates the current page immediately
- Provides plugin-owned filter, sort, and CSV export controls
- Triggers full-scan flow only when filter, sort, or export is used

## Manual Verification

1. Load the unpacked extension from `dist/`
2. Open `https://xingtu.cn/ad/creator/market`
3. Confirm the two new columns appear
4. Confirm current-page rows move through loading and then render values or failure states
5. Apply a threshold filter and confirm the list hides unmatched rows
6. Apply a sort and confirm row order changes
7. Export CSV and confirm the file includes plugin status and after-search-rate fields
