+## 🚨 异常处理完整性检查（关键规范）
+
+### 问题定义
+**异常吞没（Exception Swallowing）** 是指在 catch 块中捕获异常后，只记录日志但不重新抛出，导致：
+- 调用方无法感知错误
+- 方法返回 undefined 而非声明的类型
+- 数据不一致或静默失败
+- 难以调试和定位问题
+
+### 检查规则
+
+#### 规则1：catch 块必须有明确的异常处理策略
+```typescript
+// ❌ 严重错误：catch 块吞没异常
+async create(createDto: CreateDto): Promise<ResponseDto> {
+  try {
+    const result = await this.repository.create(createDto);
+    return this.toResponseDto(result);
+  } catch (error) {
+    this.logger.error('创建失败', error);
+    // 错误：没有 throw，方法返回 undefined
+    // 但声明返回 Promise<ResponseDto>
+  }
+}
+
+// ❌ 错误：只记录日志不处理
+async findById(id: string): Promise<Entity> {
+  try {
+    return await this.repository.findById(id);
+  } catch (error) {
+    monitor.error(error);
+    // 错误：异常被吞没，调用方无法感知
+  }
+}
+
+// ✅ 正确：重新抛出异常
+async create(createDto: CreateDto): Promise<ResponseDto> {
+  try {
+    const result = await this.repository.create(createDto);
+    return this.toResponseDto(result);
+  } catch (error) {
+    this.logger.error('创建失败', error);
+    throw error;  // 必须重新抛出
+  }
+}
+
+// ✅ 正确：转换为特定异常类型
+async create(createDto: CreateDto): Promise<ResponseDto> {
+  try {
+    const result = await this.repository.create(createDto);
+    return this.toResponseDto(result);
+  } catch (error) {
+    this.logger.error('创建失败', error);
+    if (error.message.includes('duplicate')) {
+      throw new ConflictException('记录已存在');
+    }
+    throw error;  // 其他错误继续抛出
+  }
+}
+
+// ✅ 正确：返回错误响应（仅限顶层API）
+async create(createDto: CreateDto): Promise<ApiResponse<ResponseDto>> {
+  try {
+    const result = await this.repository.create(createDto);
+    return { success: true, data: this.toResponseDto(result) };
+  } catch (error) {
+    this.logger.error('创建失败', error);
+    return { 
+      success: false, 
+      error: error.message,
+      errorCode: 'CREATE_FAILED'
+    };  // 顶层API可以返回错误响应
+  }
+}
+```
+
+#### 规则2：Service 层方法必须传播异常
+```typescript
+// ❌ 错误：Service 层吞没异常
+@Injectable()
+export class UserService {
+  async update(id: string, dto: UpdateDto): Promise<ResponseDto> {
+    try {
+      const result = await this.repository.update(id, dto);
+      return this.toResponseDto(result);
+    } catch (error) {
+      this.logger.error('更新失败', { id, error });
+      // 错误：Service 层不应吞没异常
+    }
+  }
+}
+
+// ✅ 正确：Service 层传播异常
+@Injectable()
+export class UserService {
+  async update(id: string, dto: UpdateDto): Promise<ResponseDto> {
+    try {
+      const result = await this.repository.update(id, dto);
+      return this.toResponseDto(result);
+    } catch (error) {
+      this.logger.error('更新失败', { id, error });
+      throw error;  // 传播给调用方处理
+    }
+  }
+}
+```
+
+#### 规则3：Repository 层必须传播数据库异常
+```typescript
+// ❌ 错误：Repository 层吞没数据库异常
+@Injectable()
+export class UserRepository {
+  async findById(id: bigint): Promise<User | null> {
+    try {
+      return await this.repository.findOne({ where: { id } });
+    } catch (error) {
+      this.logger.error('查询失败', { id, error });
+      // 错误：数据库异常被吞没，调用方以为查询成功但返回 null
+    }
+  }
+}
+
+// ✅ 正确：Repository 层传播异常
+@Injectable()
+export class UserRepository {
+  async findById(id: bigint): Promise<User | null> {
+    try {
+      return await this.repository.findOne({ where: { id } });
+    } catch (error) {
+      this.logger.error('查询失败', { id, error });
+      throw error;  // 数据库异常必须传播
+    }
+  }
+}
+```
+
+### 异常处理层级规范
+
+| 层级 | 异常处理策略 | 说明 |
+|------|-------------|------|
+| **Repository 层** | 必须 throw | 数据访问异常必须传播 |
+| **Service 层** | 必须 throw | 业务异常必须传播给调用方 |
+| **Business 层** | 必须 throw | 业务逻辑异常必须传播 |
+| **Gateway/Controller 层** | 可以转换为 HTTP 响应 | 顶层可以将异常转换为错误响应 |
+
+### 检查清单
+
+- [ ] **所有 catch 块是否有 throw 语句？**
+- [ ] **方法返回类型与实际返回是否一致？**（避免返回 undefined）
+- [ ] **Service/Repository 层是否传播异常？**
+- [ ] **只有顶层 API 才能将异常转换为错误响应？**
+- [ ] **异常日志是否包含足够的上下文信息？**
+
+### 快速检查命令
+```bash
+# 搜索可能吞没异常的 catch 块（没有 throw 的 catch）
+# 在代码审查时重点关注这些位置
+grep -rn "catch.*error" --include="*.ts" | grep -v "throw"
+```
+
+### 常见错误模式
+
+#### 模式1：性能监控后忘记抛出
+```typescript
+// ❌ 常见错误
+} catch (error) {
+  monitor.error(error);  // 只记录监控
+  // 忘记 throw error;
+}
+
+// ✅ 正确
+} catch (error) {
+  monitor.error(error);
+  throw error;  // 必须抛出
+}
+```
+
+#### 模式2：条件分支遗漏 throw
+```typescript
+// ❌ 常见错误
+} catch (error) {
+  if (error.code === 'DUPLICATE') {
+    throw new ConflictException('已存在');
+  }
+  // else 分支忘记 throw
+  this.logger.error(error);
+}
+
+// ✅ 正确
+} catch (error) {
+  if (error.code === 'DUPLICATE') {
+    throw new ConflictException('已存在');
+  }
+  this.logger.error(error);
+  throw error;  // else 分支也要抛出
+}
+```
+
+#### 模式3：返回类型不匹配
+```typescript
+// ❌ 错误：声明返回 Promise<Entity> 但可能返回 undefined
+async findById(id: string): Promise<Entity> {
+  try {
+    return await this.repo.findById(id);
+  } catch (error) {
+    this.logger.error(error);
+    // 没有 throw，TypeScript 不会报错但运行时返回 undefined
+  }
+}
+
+// ✅ 正确
+async findById(id: string): Promise<Entity> {
+  try {
+    return await this.repo.findById(id);
+  } catch (error) {
+    this.logger.error(error);
+    throw error;

+    - 如有启动错误，必须修复后重新验证
+
+## 🚀 应用启动验证（强制要求）
+
+### 为什么需要启动验证？
+**静态代码检查无法发现所有的模块依赖问题！** 以下问题只有在应用启动时才会暴露：
+
+1. **Module exports 配置错误**：导出了不属于当前模块的服务
+2. **依赖注入链断裂**：中间模块未正确导出依赖
+3. **循环依赖问题**：模块间存在循环引用
+4. **Provider 注册遗漏**：服务未在正确的模块中注册
+5. **CacheModule/ConfigModule 等全局模块缺失**
+
+### 常见启动错误示例
+
+#### 错误1：导出不属于当前模块的服务
+```
+UnknownExportException [Error]: Nest cannot export a provider/module that 
+is not a part of the currently processed module (ZulipModule). 
+Please verify whether the exported DynamicConfigManagerService is available 
+in this particular context.
+```
+
+**原因**：ZulipModule 尝试导出 DynamicConfigManagerService，但该服务来自 ZulipCoreModule，不是 ZulipModule 自己的 provider。
+
+**修复方案**：
+```typescript
+// ❌ 错误：直接导出其他模块的服务
+@Module({
+  imports: [ZulipCoreModule],
+  exports: [DynamicConfigManagerService],  // 错误！
+})
+export class ZulipModule {}
+
+// ✅ 正确：导出整个模块
+@Module({
+  imports: [ZulipCoreModule],
+  exports: [ZulipCoreModule],  // 正确：导出模块而非服务
+})
+export class ZulipModule {}
+```
+
+#### 错误2：依赖注入失败
+```
+Nest can't resolve dependencies of the JwtAuthGuard (?). 
+Please make sure that the argument LoginCoreService at index [0] 
+is available in the ZulipGatewayModule context.
+```
+
+**原因**：JwtAuthGuard 需要 LoginCoreService，但 ZulipGatewayModule 没有导入 LoginCoreModule。
+
+**修复方案**：
+```typescript
+// ❌ 错误：缺少必要的模块导入
+@Module({
+  imports: [ZulipModule, AuthModule],
+  providers: [JwtAuthGuard],
+})
+export class ZulipGatewayModule {}
+
+// ✅ 正确：添加缺失的模块导入
+@Module({
+  imports: [
+    ZulipModule, 
+    AuthModule,
+    LoginCoreModule,  // 添加：JwtAuthGuard 依赖 LoginCoreService
+  ],
+  providers: [JwtAuthGuard],
+})
+export class ZulipGatewayModule {}
+```
+
+#### 错误3：CACHE_MANAGER 未注册
+```
+Nest can't resolve dependencies of the SomeService (?). 
+Please make sure that the argument "CACHE_MANAGER" at index [2] 
+is available in the SomeModule context.
+```
+
+**原因**：服务使用了 @Inject(CACHE_MANAGER)，但模块未导入 CacheModule。
+
+**修复方案**：
+```typescript
+// ❌ 错误：缺少 CacheModule
+@Module({
+  imports: [OtherModule],
+  providers: [SomeService],
+})
+export class SomeModule {}
+
+// ✅ 正确：添加 CacheModule
+import { CacheModule } from '@nestjs/cache-manager';
+
+@Module({
+  imports: [
+    CacheModule.register(),  // 添加缓存模块
+    OtherModule,
+  ],
+  providers: [SomeService],
+})
+export class SomeModule {}
+```
+
+### 启动验证执行流程
+
+```bash
+# 1. 执行启动命令
+pnpm dev
+# 或
+npm run dev
+
+# 2. 观察控制台输出，检查是否有以下错误类型：
+# - UnknownExportException
+# - Nest can't resolve dependencies
+# - Circular dependency detected
+# - Module not found
+
+# 3. 如果启动成功，应该看到类似输出：
+# [Nest] LOG [NestFactory] Starting Nest application...
+# [Nest] LOG [RoutesResolver] AppController {/}: +Xms
+# [Nest] LOG [NestApplication] Nest application successfully started +Xms
+
+# 4. 验证健康检查接口
+curl http://localhost:3000/health
+# 应返回：{"status":"ok",...}
+```
+
+### 启动验证检查清单
+
+- [ ] 执行 `pnpm dev` 或 `npm run dev`
+- [ ] 确认无 UnknownExportException 错误
+- [ ] 确认无依赖注入失败错误
+- [ ] 确认无循环依赖错误
+- [ ] 确认应用成功启动并监听端口
+- [ ] 验证健康检查接口返回正常
+- [ ] 如有错误，修复后重新启动验证
+
+### 🚨 启动验证失败处理
+
+**如果启动验证失败，必须：**
+1. **分析错误信息**：识别具体的模块和依赖问题
+2. **定位问题模块**：找到报错的 Module 文件
+3. **修复依赖配置**：
+   - 添加缺失的 imports
+   - 修正错误的 exports
+   - 注册缺失的 providers
+4. **重新启动验证**：修复后必须再次执行启动验证
+5. **记录修改**：更新文件头部的修改记录

+# Chat 聊天业务模块
+
+Chat 模块是游戏服务器的核心聊天业务层，负责实现游戏内实时聊天功能，包括玩家会话管理、消息过滤、位置追踪和 Zulip 异步同步。该模块通过 SESSION_QUERY_SERVICE 接口向其他业务模块提供会话查询能力。
+
+## 对外提供的接口
+
+### ChatService
+
+#### handlePlayerLogin(request: PlayerLoginRequest): Promise<LoginResponse>
+处理玩家登录，验证 Token 并创建游戏会话。
+
+#### handlePlayerLogout(socketId: string, reason?: string): Promise<void>
+处理玩家登出，清理会话和相关资源。
+
+#### sendChatMessage(request: ChatMessageRequest): Promise<ChatMessageResponse>
+发送聊天消息，包含内容过滤、实时广播和 Zulip 异步同步。
+
+#### updatePlayerPosition(request: PositionUpdateRequest): Promise<boolean>
+更新玩家在游戏地图中的位置。
+
+#### getChatHistory(query: object): Promise<object>
+获取聊天历史记录。
+
+#### getSession(socketId: string): Promise<GameSession | null>
+获取指定 WebSocket 连接的会话信息。
+
+### ChatSessionService (实现 ISessionManagerService)
+
+#### createSession(socketId, userId, zulipQueueId, username?, initialMap?, initialPosition?): Promise<GameSession>
+创建新的游戏会话，建立 WebSocket 与用户的映射关系。
+
+#### getSession(socketId: string): Promise<GameSession | null>
+获取会话信息并更新最后活动时间。
+
+#### destroySession(socketId: string): Promise<boolean>
+销毁会话并清理相关资源。
+
+#### injectContext(socketId: string, mapId?: string): Promise<ContextInfo>
+根据玩家位置注入聊天上下文（Stream/Topic）。
+
+#### updatePlayerPosition(socketId, mapId, x, y): Promise<boolean>
+更新玩家位置，支持跨地图切换。
+
+#### getSocketsInMap(mapId: string): Promise<string[]>
+获取指定地图中的所有在线玩家 Socket。
+
+#### cleanupExpiredSessions(timeoutMinutes?: number): Promise<object>
+清理过期会话，返回清理数量和 Zulip 队列 ID 列表。
+
+### ChatFilterService
+
+#### validateMessage(userId, content, targetStream, currentMap): Promise<object>
+综合验证消息，包含频率限制、内容过滤和权限验证。
+
+#### filterContent(content: string): Promise<ContentFilterResult>
+过滤消息内容，检测敏感词、重复字符和恶意链接。
+
+#### checkRateLimit(userId: string): Promise<boolean>
+检查用户发送消息的频率是否超限。
+
+#### validatePermission(userId, targetStream, currentMap): Promise<boolean>
+验证用户是否有权限向目标频道发送消息。
+
+### ChatCleanupService
+
+#### triggerCleanup(): Promise<{ cleanedCount: number }>
+手动触发会话清理，返回清理的会话数量。
+
+## 使用的项目内部依赖
+
+### IZulipClientPoolService (来自 core/zulip_core)
+Zulip 客户端连接池服务，用于创建/销毁用户客户端和发送消息。
+
+### IApiKeySecurityService (来自 core/zulip_core)
+API Key 安全服务，用于获取和删除用户的 Zulip API Key。
+
+### IZulipConfigService (来自 core/zulip_core)
+Zulip 配置服务，提供地图与 Stream 的映射关系和附近对象查询。
+
+### IRedisService (来自 core/redis)
+Redis 缓存服务，用于存储会话数据、地图玩家列表和频率限制计数。
+
+### LoginCoreService (来自 core/login_core)
+登录核心服务，用于验证 JWT Token。
+
+### ISessionManagerService (来自 core/session_core)
+会话管理接口定义，ChatSessionService 实现此接口供其他模块依赖。
+
+## 核心特性
+
+### 实时聊天 + 异步同步架构
+- 🚀 游戏内实时广播：消息直接广播给同地图玩家，延迟极低
+- 🔄 Zulip 异步同步：消息异步存储到 Zulip，保证持久化
+- ⚡ 低延迟体验：先广播后同步，不阻塞用户操作
+
+### 基于位置的聊天上下文
+- 根据玩家当前地图自动确定 Zulip Stream
+- 根据玩家位置附近的对象自动确定 Topic
+- 支持跨地图切换时自动更新聊天频道
+
+### 会话生命周期管理
+- 自动清理旧会话，防止重复登录
+- 定时清理过期会话（默认 30 分钟无活动）
+- 支持手动触发清理操作
+
+### 内容安全和频率控制
+- 敏感词过滤（支持替换和阻止两种模式）
+- 频率限制（默认 60 秒内最多 10 条消息）
+- 恶意链接检测和黑名单域名过滤
+- 重复字符和刷屏检测
+
+## 潜在风险
+
+### Redis 连接故障风险
+- 会话数据存储在 Redis，连接故障会导致会话丢失
+- 缓解措施：Redis 集群部署、连接重试机制
+
+### Zulip 同步延迟风险
+- 异步同步可能导致消息在 Zulip 中延迟出现
+- 缓解措施：消息队列、重试机制、失败告警
+
+### 高并发广播性能风险
+- 同一地图玩家过多时广播性能下降
+- 缓解措施：分片广播、消息合并、限制单地图人数
+
+### 会话清理遗漏风险
+- 定时清理可能遗漏部分过期会话
+- 缓解措施：多次清理、Redis 过期策略配合

 ## 核心特性
 
-### 双向通信支持
-- WebSocket实时通信：支持游戏客户端与服务器的实时双向通信
-- Zulip集成同步：实现游戏内聊天与Zulip社群的双向消息同步
-- 事件驱动架构：基于事件队列处理Zulip消息推送和游戏事件
+### 事件队列轮询机制
+- 支持多用户并发事件队列管理
+- 2秒轮询间隔，非阻塞模式获取事件
+- 自动处理队列错误和重连机制
+- 支持队列的动态注册和注销
 
-### 会话状态管理
-- Redis持久化存储：会话数据存储在Redis中，支持服务重启后状态恢复
-- 自动过期清理：定时清理超时会话，释放系统资源
-- 多地图支持：支持玩家在不同地图间切换，自动更新地图玩家列表
+### 消息格式转换
+- Zulip消息到游戏协议（chat_render）的自动转换
+- Markdown格式移除，保留纯文本内容
+- HTML标签清理和实体解码
+- 消息长度限制（200字符）和截断处理
 
-### 消息过滤和安全
-- 敏感词过滤：支持block和replace两种级别的敏感词处理
-- 频率限制控制：防止用户发送消息过于频繁导致刷屏
-- 位置权限验证：防止用户向不匹配位置的Stream发送消息
-- 违规行为记录：记录和统计用户违规行为，支持监控和分析
+### 空间过滤机制
+- 根据Zulip Stream确定对应的游戏地图
+- 从SessionManager获取地图内的在线玩家
+- 自动排除消息发送者，避免收到自己的消息
+- 支持区域广播功能
 
-### 业务规则引擎
-- 上下文注入机制：根据玩家位置自动确定消息的目标Stream和Topic
-- 动态配置管理：支持地图到Stream映射关系的动态配置和热重载
-- 权限分级控制：支持不同用户角色的权限控制和消息发送限制
+### 缓存优化
+- 账号查询结果缓存（5分钟TTL）
+- 统计数据缓存（1分钟TTL）
+- 自动缓存失效和更新机制
+- 缓存键前缀隔离
+
+### 性能监控
+- 操作耗时记录和日志输出
+- 事件处理统计（处理事件数、消息数）
+- 队列状态监控（活跃队列数、总队列数）
+- 最后事件时间追踪
 
 ## 潜在风险
 
-### 会话数据丢失
-- Redis服务故障可能导致会话数据丢失，影响用户体验
-- 建议配置Redis主从复制和持久化策略
-- 实现会话数据的定期备份和恢复机制
+### 事件队列连接风险
+- Zulip服务器不可用时事件队列无法获取
+- 队列ID过期导致BAD_EVENT_QUEUE_ID错误
+- 网络不稳定时轮询失败
+- 缓解措施：自动禁用错误队列、支持队列重新激活、错误日志记录
 
-### 消息同步延迟
-- Zulip服务器网络延迟可能影响消息同步实时性
-- 大量并发消息可能导致事件队列处理延迟
-- 建议监控消息处理延迟并设置合理的超时机制
+### 消息分发延迟风险
+- 大量并发消息可能导致分发延迟
+- WebSocket连接断开时消息丢失
+- 目标玩家列表过大时性能下降
+- 缓解措施：异步分发、连接状态检查、分批发送
 
-### 频率限制绕过
-- 恶意用户可能通过多个账号绕过频率限制
-- IP级别的频率限制可能影响正常用户
-- 建议结合用户行为分析和动态调整限制策略
+### 缓存一致性风险
+- 缓存数据与数据库不一致
+- 缓存清理失败导致脏数据
+- 高并发下缓存穿透
+- 缓解措施：写操作后主动清理缓存、缓存失败降级查询、合理设置TTL
 
-### 敏感词过滤失效
-- 新型敏感词和变体可能绕过现有过滤规则
-- 过度严格的过滤可能影响正常交流
-- 建议定期更新敏感词库并优化过滤算法
+### 内存泄漏风险
+- 事件队列未正确注销导致内存累积
+- 长时间运行后统计数据累积
+- 缓解措施：模块销毁时清理资源、提供统计重置接口
 
-### WebSocket连接稳定性
-- 网络不稳定可能导致WebSocket连接频繁断开重连
-- 大量连接可能消耗过多服务器资源
-- 建议实现连接池管理和自动重连机制
+## 架构定位
 
-### 位置验证绕过
-- 客户端修改可能绕过位置验证机制
-- 服务端位置验证逻辑需要持续完善
-- 建议结合多种验证手段和异常行为检测
+- **层级**: Business层（业务层）
+- **职责**: 业务逻辑处理、服务协调
+- **依赖**: Core层的ZulipCoreModule、ZulipAccountsModule等
 
-## 使用示例
+## 文件结构

-## 版本信息
-- **版本**: 1.3.0
-- **作者**: angjustinl
-- **创建时间**: 2025-12-20
-- **最后修改**: 2026-01-12
+### Business层禁止
+- 包含HTTP协议处理（Controller应在Gateway层）
+- 直接访问数据库（应通过Core层Repository）
+- 包含技术实现细节
 
-## 最近修改记录
-- 2026-01-12: 功能新增 - 添加完整的WebSocket事件接口文档，包含所有事件的输入输出格式说明 (修改者: moyin)
-- 2026-01-07: 功能修改 - 更新业务逻辑和接口描述 (修改者: angjustinl)
-- 2025-12-20: 功能新增 - 创建Zulip游戏集成业务模块文档 (修改者: angjustinl)
+## 迁移说明
+
+### 2026-01-14 架构优化
+
+**Controller迁移到Gateway层**
+
+所有Controller已从本模块迁移到 `src/gateway/zulip/`：
+- `DynamicConfigController` -> `src/gateway/zulip/dynamic_config.controller.ts`
+- `WebSocketDocsController` -> `src/gateway/zulip/websocket_docs.controller.ts`
+- `WebSocketOpenApiController` -> `src/gateway/zulip/websocket_openapi.controller.ts`
+- `WebSocketTestController` -> `src/gateway/zulip/websocket_test.controller.ts`
+- `ZulipAccountsController` -> `src/gateway/zulip/zulip_accounts.controller.ts`
+
+**原因**：符合四层架构规范，Controller属于Gateway层（HTTP协议处理），不应在Business层。
+
+## 相关文档

+- [Gateway层Zulip模块](../../gateway/zulip/README.md)
+- [架构文档](../../../docs/ARCHITECTURE.md)
+- [开发指南](../../../docs/development/backend_development_guide.md)
+
+## 最近更新
+
+- 2026-01-14: 功能文档完善 - 补充对外接口、内部依赖、核心特性、潜在风险章节 (moyin)
+- 2026-01-14: 架构优化 - Controller迁移到Gateway层 (moyin)
+- 2026-01-14: 聊天功能迁移到business/chat模块 (moyin)

+# SessionCore 会话核心模块
+
+SessionCore 是为会话管理业务提供技术支撑的核心模块，定义了会话管理的抽象接口，实现 Business 层模块间的解耦。
+
+## 对外提供的接口
+
+### ISessionQueryService（会话查询服务接口）
+
+提供只读的会话查询能力，用于跨模块查询会话信息。
+
+#### getSession(socketId: string): Promise<IGameSession | null>
+获取指定 WebSocket 连接的会话信息，不存在时返回 null。
+
+#### getSocketsInMap(mapId: string): Promise<string[]>
+获取指定地图中所有活跃的 Socket ID 列表。
+
+### ISessionManagerService（会话管理服务接口）
+
+提供完整的会话管理能力，包括创建、更新、删除操作，继承自 ISessionQueryService。
+
+#### createSession(socketId, userId, zulipQueueId, username?, initialMap?, initialPosition?): Promise<IGameSession>
+创建新的游戏会话，关联 WebSocket 连接、用户信息和 Zulip 事件队列。
+
+#### injectContext(socketId: string, mapId?: string): Promise<IContextInfo>
+根据玩家位置确定 Zulip Stream 和 Topic，实现上下文注入。
+
+#### updatePlayerPosition(socketId: string, mapId: string, x: number, y: number): Promise<boolean>
+更新玩家在地图中的位置坐标。
+
+#### destroySession(socketId: string): Promise<boolean>
+销毁指定的会话，清理相关资源。
+
+#### cleanupExpiredSessions(timeoutMinutes?: number): Promise<{ cleanedCount: number; zulipQueueIds: string[] }>
+清理超时的过期会话，返回清理数量和对应的 Zulip 队列 ID 列表。
+
+### SessionCoreModule（会话核心模块）
+
+#### forFeature(options: SessionCoreModuleOptions): DynamicModule
+注册会话服务提供者，支持动态配置会话查询和管理服务的实现。
+
+## 使用的项目内部依赖
+
+### IPosition (本模块)
+位置信息接口，定义 x 和 y 坐标。
+
+### IGameSession (本模块)
+游戏会话接口，包含 socketId、userId、username、zulipQueueId、currentMap、position、lastActivity、createdAt 等字段。
+
+### IContextInfo (本模块)
+上下文信息接口，包含 stream 和可选的 topic 字段。
+
+### SESSION_QUERY_SERVICE (本模块)
+会话查询服务的依赖注入 Token。
+
+### SESSION_MANAGER_SERVICE (本模块)
+会话管理服务的依赖注入 Token。
+
+## 核心特性
+
+### 接口抽象设计
+- 定义抽象接口，不包含具体实现
+- 实现由 Business 层的 ChatModule 提供
+- 支持依赖注入和模块解耦
+
+### 动态模块配置
+- 使用 forFeature 方法支持灵活配置
+- 可单独注册查询服务或管理服务
+- 支持同时注册多个服务提供者
+
+### 分离查询和管理职责
+- ISessionQueryService 提供只读查询能力
+- ISessionManagerService 提供完整管理能力
+- 清晰的职责分离，便于权限控制
+
+### 跨模块会话查询
+- 其他模块可通过 SESSION_QUERY_SERVICE 查询会话信息
+- 不需要直接依赖 Business 层实现
+- 实现模块间的松耦合
+
+## 潜在风险
+
+### 接口实现缺失风险
+- Core 层只定义接口，不提供实现
+- 如果 Business 层未正确注册实现，会导致运行时错误
+- 缓解措施：在模块导入时验证服务提供者配置
+
+### 依赖注入配置错误风险
+- forFeature 配置不当可能导致服务无法注入
+- Token 名称错误会导致依赖解析失败
+- 缓解措施：使用 TypeScript 类型检查和单元测试验证
+
+### 接口变更影响范围风险
+- 接口定义变更会影响所有实现和使用方
+- 可能导致多个模块需要同步修改
+- 缓解措施：保持接口稳定，使用版本化管理
+
+### 循环依赖风险
+- 如果 Business 层实现反向依赖 Core 层其他模块
+- 可能形成循环依赖导致模块加载失败
+- 缓解措施：严格遵守分层架构，Core 层不依赖 Business 层

+# 聊天网关模块 (Chat Gateway Module)
+
+聊天网关模块是聊天系统的协议入口，负责处理 WebSocket 和 HTTP 请求，提供统一的 API 接口。作为 Gateway Layer 的核心组件，它专注于协议转换和路由管理，将客户端请求转发到 Business Layer 处理，不包含业务逻辑。
+
+## 架构层级
+
+**Gateway Layer（网关层）**
+
+## 职责定位
+
+网关层负责：
+
+1. **协议处理**：处理 WebSocket 和 HTTP 请求
+2. **数据验证**：使用 DTO 进行请求参数验证
+3. **路由管理**：定义 API 端点和消息路由
+4. **错误转换**：将业务错误转换为协议响应

+
+### ChatModule (来自 business/chat/chat.module)
+聊天业务模块，提供聊天相关的业务逻辑处理。
+
+## 核心特性
+
+### WebSocket 连接管理
+- 原生 WebSocket 支持：基于 ws 库的原生 WebSocket 实现
+- 连接生命周期管理：自动处理连接建立、认证、断开和清理
+- 连接状态追踪：维护连接 ID、认证状态、用户信息等
+- 心跳检测机制：通过 isAlive 标记检测连接活性
+
+### 地图房间系统
+- 动态房间管理：根据玩家所在地图自动创建和销毁房间
+- 房间成员追踪：维护每个地图的玩家列表
+- 自动房间切换：玩家切换地图时自动加入新房间并离开旧房间
+- 房间广播优化：仅向房间内的已认证玩家广播消息
+
+### 实时消息广播
+- 单播通信：向指定玩家发送消息
+- 地图广播：向地图内所有玩家广播消息，支持排除发送者
+- 位置同步：实时广播玩家位置更新给房间成员
+- 聊天消息推送：接收业务层的聊天消息并推送给客户端
+
+### 协议转换与路由
+- 消息类型路由：根据消息类型自动路由到对应处理方法
+- 协议格式统一：统一 WebSocket 和 HTTP 的响应格式
+- 错误转换：将业务层错误转换为客户端友好的错误消息
+- DTO 数据验证：使用 class-validator 进行请求参数验证
+
+### 监控与统计
+- 连接数统计：实时统计总连接数和已认证连接数
+- 地图人数统计：统计各地图的在线玩家数量
+- 系统状态监控：提供内存使用、运行时间等系统指标
+- 日志记录：记录连接、消息、错误等关键事件
+
+## 潜在风险
+
+### WebSocket 连接管理风险
+- 大量并发连接可能导致内存占用过高
+- 连接泄漏风险：异常断开时可能未正确清理资源
+- 僵尸连接问题：网络异常时连接可能长时间挂起
+- 缓解措施：实现连接数限制、定期清理超时连接、完善错误处理
+
+### 实时通信性能风险
+- 高频位置更新可能导致服务器 CPU 压力
+- 大房间广播延迟：房间人数过多时广播性能下降
+- 消息队列堆积：处理速度慢于接收速度时消息堆积
+- 缓解措施：位置更新限流、分片广播、消息优先级队列
+
+### 认证与安全风险
+- JWT token 泄露风险：WebSocket 连接中 token 可能被截获
+- 未认证消息攻击：恶意客户端可能发送大量未认证消息
+- 消息内容安全：缺少消息内容的安全过滤
+- 缓解措施：使用 WSS 加密传输、限制未认证连接的消息频率、在业务层进行内容过滤
+
+### 资源清理风险
+- 断开连接时资源清理不完整可能导致内存泄漏
+- 地图房间未及时清理导致空房间占用内存
+- 客户端映射未清理导致无效引用
+- 缓解措施：完善 cleanupClient 方法、定期清理空房间、使用 WeakMap 避免内存泄漏
+
+### 错误处理风险
+- 业务层异常未正确捕获可能导致连接中断
+- 消息解析失败可能导致连接关闭
+- 错误信息泄露敏感信息
+- 缓解措施：完善 try-catch 覆盖、统一错误处理、脱敏错误消息
+
+### 扩展性风险
+- 单实例 WebSocket 服务器无法水平扩展
+- 内存存储的房间信息无法跨实例共享
+- 负载均衡时 WebSocket 连接可能断开
+- 缓解措施：引入 Redis 共享房间信息、使用 Sticky Session、实现 WebSocket 集群
+
+## 核心原则
+
+### 1. 只做协议转换，不做业务逻辑
+
+```typescript
+// ✅ 正确：只做协议处理
+private async handleChat(ws: ExtendedWebSocket, message: any) {
+  if (!ws.authenticated) {
+    this.sendError(ws, '请先登录');
+    return;
+  }
+
+  const result = await this.chatService.sendChatMessage({
+    socketId: ws.id,
+    content: message.content,
+    scope: message.scope || 'local'
+  });
+
+  if (result.success) {
+    this.sendMessage(ws, { t: 'chat_sent', messageId: result.messageId });
+  } else {
+    this.sendMessage(ws, { t: 'chat_error', message: result.error });
+  }
+}
+
+// ❌ 错误：在网关中包含业务逻辑
+private async handleChat(ws: ExtendedWebSocket, message: any) {
+  // 不应该在这里做敏感词过滤、频率限制等业务逻辑
+  if (message.content.includes('敏感词')) {
+    this.sendError(ws, '包含敏感词');
+    return;
+  }
+}
+```
+
+### 2. 统一的错误处理
+
+```typescript
+private sendError(ws: ExtendedWebSocket, message: string) {
+  this.sendMessage(ws, { type: 'error', message });
+}
+```
+
+## 使用示例
+
+### WebSocket 连接示例
+
+```javascript
+const ws = new WebSocket('wss://whaletownend.xinghangee.icu/game');
+
+ws.onopen = () => {
+  // 登录
+  ws.send(JSON.stringify({
+    type: 'login',
+    token: 'your-jwt-token'
+  }));
+};
+
+ws.onmessage = (event) => {
+  const data = JSON.parse(event.data);
+  
+  switch (data.t || data.type) {
+    case 'login_success':
+      console.log('登录成功', data);
+      break;
+    case 'chat_render':
+      console.log('收到消息', data.from, data.txt);
+      break;
+  }
+};
+
+// 发送聊天消息
+ws.send(JSON.stringify({
+  type: 'chat',
+  content: '大家好！',
+  scope: 'local'
+}));
+```
+
+## 注意事项
+
+- 网关层不应该直接访问数据库
+- 网关层不应该包含复杂的业务逻辑
+- 所有业务逻辑都应该在 Business 层实现
+- WebSocket 连接需要先登录才能发送聊天消息

+# Zulip Gateway Module
+
+## 📋 模块概述
+
+Zulip网关模块，负责提供Zulip相关功能的HTTP API接口。
+
+## 🏗️ 架构定位
+
+- **层级**: Gateway层（网关层）
+- **职责**: HTTP协议处理、API接口暴露、请求验证
+- **依赖**: Business层的ZulipModule
+
+## 📁 文件结构
+
+```

+└── README.md                             # 本文档
+```
+
+## 🎯 主要功能
+
+### 1. 动态配置管理 (DynamicConfigController)
+- 获取当前配置
+- 同步远程配置
+- 配置状态查询
+- 备份管理
+
+### 2. WebSocket文档 (WebSocketDocsController)
+- 提供WebSocket API使用文档
+- 消息格式示例
+- 连接示例代码
+
+### 3. WebSocket OpenAPI (WebSocketOpenApiController)
+- 在Swagger中展示WebSocket接口
+- 提供测试工具推荐
+- 架构信息展示
+
+### 4. WebSocket测试工具 (WebSocketTestController)
+- 交互式WebSocket测试页面
+- 支持连接、认证、消息发送测试
+- API调用监控功能
+
+### 5. Zulip账号管理 (ZulipAccountsController)
+- Zulip账号关联CRUD操作
+- 账号验证和统计
+- 批量管理功能
+
+## 🔗 依赖关系
+
+```
+ZulipGatewayModule
+  ├─ imports: ZulipModule (Business层)
+  ├─ imports: AuthModule (Business层)
+  └─ controllers: [所有Controller]
+```
+
+## 📝 使用示例
+
+### 在AppModule中导入
+
+```typescript
+import { ZulipGatewayModule } from './gateway/zulip/zulip.gateway.module';
+
+@Module({
+  imports: [
+    // ... 其他模块
+    ZulipGatewayModule,
+  ],
+})
+export class AppModule {}
+```
+
+## 🚨 架构规范
+
+### Gateway层职责
+- ✅ HTTP协议处理
+- ✅ 请求参数验证（DTO）
+- ✅ 调用Business层服务
+- ✅ 响应格式转换
+- ✅ 错误处理和转换
+
+### Gateway层禁止
+- ❌ 包含业务逻辑
+- ❌ 直接访问数据库
+- ❌ 直接调用Core层（应通过Business层）
+- ❌ 包含复杂的业务规则
+
+## 📚 相关文档
