# M14-04C：Chromium mouse/touch/pen pointer identity and cancellation contract
|
||
|
||
- `task`: `M14-04C`
|
||
- `parent`: `M14-04B`
|
||
- `status`: `in_progress`
|
||
|
||
## 目标
|
||
|
||
为 Chromium 生产输入路径建立统一 pointer observation：mouse、touch、pen 分别保留
|
||
`pointerType`、`pointerId`、`pressure`、`tiltX`、`tiltY`、`button`、`buttons` 和 cancel 状态；
|
||
未知或越界值 fail-closed，不把触控/笔事件伪装成 mouse。Firefox/WebKit 不在本项目范围内。
|
||
|
||
## 验收
|
||
|
||
```text
|
||
npm --prefix web run test:chromium-pointer-contract
|
||
```
