+| `/session` | 显示当前项目前 10 个会话，当前会话标 `◀` |
+| `/session list` | 显示全部会话 |
+| `/session n` | 切换到第 n 个会话 |
+
+### 设计
+
+每个 `chatId` 维护一个"当前会话"状态（`_chatSessions[chatId]`），优先级高于线程级 `sessionMap[chatId:rootId]`。
+
+- `/session n` 设置 `_chatSessions[chatId]`，后续所有消息都发往该会话
+- `/new` 清除并立即新建，新会话存入 `_chatSessions[chatId]`
+- `/project n` 切换项目时，将目标项目的最近会话存入 `_chatSessions[chatId]`
+- `stop()` 清除所有 `_chatSessions`（不持久化）
+
 ### 数据来源
 
 `getProjects()` 直接调用 `Project.recentList()`，这与微信端调用的 `GET /project/recent` HTTP 接口是**同一个函数**，因此两端看到的项目列表完全一致。
