     3. 安装依赖并修复 TypeScript 构建问题，完成生产构建验证。
 - **执行结果**: 项目已可运行并可构建，页面可显示基础 3D 场景与 RPG 调试面板，作为后续探索/战斗系统开发起点。
 
+# 任务执行摘要
+
+## 会话 ID: 1775839250
+- [2026-04-11 00:40:50]
+- **执行原因**: 用户要求“继续完成”，希望在现有骨架上推进可玩功能。
+- **执行过程**:
+    1. 新增输入系统与共享游戏状态，支持键盘移动与状态同步展示。
+    2. 扩展 Three.js 场景逻辑，加入角色移动、边界与障碍碰撞、区域切换、传送点占位和随机遇敌计量。
+    3. 更新状态面板为实时数据显示，并执行构建验证确保可编译运行。
+- **执行结果**: 已完成探索层 MVP，玩家可在 3D 场景中移动并获得基础 RPG 反馈，项目继续可在此基础上对接战斗系统。
