+# 计划 03 执行摘要
+
+**计划:** 01-gateway-routing-03  
+**状态:** ✓ 完成  
+**日期:** 2026-03-03
+
+## 完成的任务
+
+### 任务 1: 创建 GatewayExtensions ✓
+
+创建了 `Fengling.Platform.Infrastructure/GatewayExtensions.cs`:
+
+```csharp
+public static class GatewayExtensions
+{
+    public static IServiceCollection AddGatewayCore<TContext>(this IServiceCollection services)
+        where TContext : PlatformDbContext
+    {
+        services.AddScoped<IRouteStore, RouteStore<TContext>>();
+        services.AddScoped<IInstanceStore, InstanceStore<TContext>>();
+        services.AddScoped<IRouteManager, RouteManager>();
+        return services;
+    }
+}
+```
+
+**设计决策:**
+- 使用 `PlatformDbContext` 作为约束（而非计划中的 `GatewayDbContext`）
+- Gateway 实体已集成到 `PlatformDbContext` 中，无需单独的 `GatewayDbContext`
+
+### 任务 2: 数据库迁移 ⚠
+
+**跳过原因:** EF Core 工具在当前环境中不可用。迁移应在实际部署时生成。
+
+**迁移命令参考:**
+```bash
+cd Fengling.Platform.Infrastructure
+dotnet ef migrations add InitialGateway --startup-project ../path/to/startup
+```
+
+## 验证结果
+
+- [x] `GatewayExtensions.cs` 已创建
+- [x] 构建通过 (0 错误, 4 警告)
+- [x] `AddGatewayCore<TContext>` 方法可正常注册所有 Gateway 服务
+
+## 偏差说明
+
+| 原计划 | 实际实现 | 原因 |
+|--------|----------|------|
+| `where TContext : GatewayDbContext` | `where TContext : PlatformDbContext` | Gateway 实体已集成到 PlatformDbContext |
+| 生成 EF 迁移 | 跳过 | EF 工具不可用，推迟到部署时 |
+
+## 后续步骤
+
+- Phase 1 完成
+- 可以开始 Phase 2: Platform Core 或 Phase 3: 网关调整
