# Phase 06 Plan 02 Summary
|
||
|
||
**完成输入框 `@` 引用交互闭环：候选展示、过滤、选择、chip 渲染、删除、键盘操作与上限控制。**
|
||
|
||
## Verification
|
||
|
||
- `cd frontend && pnpm -s typecheck`
|
||
- passed
|
||
|
||
## Outcome
|
||
|
||
- 输入 `@` 可拉起 `DropdownMenu` 候选并按 query 过滤。
|
||
- 选择候选后以 chip 展示，可删除且支持去重。
|
||
- `ArrowUp/ArrowDown/Enter/Escape/Backspace` 与 `isComposing` 保护已落地。
