+# 客户端代码整合设计
+
+## 目标
+
+将分散在 `src/cli/` 和 `src/client/` 的客户端代码整合到 `src/client/` 目录。
+
+## 变更
+
+### 目录结构
+
+```
+src/
+├── client/              # 整合后的客户端模块
+│   ├── mod.rs           # 主程序入口 (run 函数)
+│   ├── input.rs         # InputHandler + InputCommand (从 cli/input.rs 合并)
+│   └── channel.rs       # CliChannel (从 cli/channel.rs 合并)
+├── cli/                 # 删除
+└── protocol.rs          # 保留
+```
+
+### 关键变更
+
+| 变更 | 说明 |
+|------|------|
+| `InputEvent::Message(String)` | 简化为只携带文本内容，不再使用 `ChatMessage` |
+| `cli` 模块删除 | 代码合并到 `client` |
+| 解耦 | `client` 不再依赖 `bus::ChatMessage` |
+
+## 实施步骤
+
+1. 创建 `src/client/input.rs` - 从 `cli/input.rs` 合并，修改 `InputEvent::Message` 为 `String`
+2. 创建 `src/client/channel.rs` - 从 `cli/channel.rs` 直接复制
+3. 更新 `src/client/mod.rs` - 更新 import
+4. 更新 `src/lib.rs` - 删除 `pub mod cli;`
+5. 删除 `src/cli/` 目录
+
+## 验证
+
+- `cargo build` 通过
+- 功能保持不变
