+# Summary: Plan 01 - Gateway Domain Entities
+
+**Phase:** 01-gateway-routing  
+**Plan:** 01  
+**Status:** ✅ Completed  
+**Date:** 2026-03-03
+
+---
+
+## Tasks Completed
+
+| Task | Status | Notes |
+|------|--------|-------|
+| Task 1: Create GatewayEnums | ✅ | RouteStatus, InstanceHealth, InstanceStatus |
+| Task 2: Create GwTenant | ✅ | 54 lines, all required fields |
+| Task 3: Create GwTenantRoute | ✅ | 74 lines, all required fields |
+| Task 4: Create GwServiceInstance | ✅ | 69 lines, all required fields |
+

+## Artifacts Created
+
+```
+Fengling.Platform.Domain/AggregatesModel/GatewayAggregate/
+├── GatewayEnums.cs      (28 lines)
+├── GwTenant.cs          (54 lines)
+├── GwTenantRoute.cs     (74 lines)
+└── GwServiceInstance.cs (69 lines)
+```
+
+---
+
+## Verification Results
+
+### GatewayEnums.cs
+- ✅ `RouteStatus` enum: Inactive=0, Active=1
+- ✅ `InstanceHealth` enum: Unhealthy=0, Healthy=1
+- ✅ `InstanceStatus` enum: Inactive=0, Active=1
+
+### GwTenant.cs
+- ✅ `Id` (long) - matches Platform convention
+- ✅ `TenantCode`, `TenantName` (string)
+- ✅ `Status` (int)
+- ✅ Audit fields: CreatedBy, CreatedTime, UpdatedBy, UpdatedTime
+- ✅ Soft delete: IsDeleted (bool)
+- ✅ Concurrency: Version (int)
+
+### GwTenantRoute.cs
+- ✅ `Id` (string, Guid-based) - YARP-compatible
+- ✅ `TenantCode` (string) - links to GwTenant
+- ✅ `ServiceName`, `ClusterId`, `PathPattern` (string)
+- ✅ `Priority` (int), `Status` (int), `IsGlobal` (bool)
+- ✅ Full audit and soft delete support
+
+### GwServiceInstance.cs
+- ✅ `Id` (string, Guid-based) - YARP-compatible
+- ✅ `ClusterId`, `DestinationId`, `Address` (string)
+- ✅ `Health`, `Weight`, `Status` (int)
+- ✅ Full audit and soft delete support
+

+
+## Design Decisions
+
+### ID Type for Route and ServiceInstance
+**Plan specified:** `long` for all IDs  
+**Implementation uses:** `string` with `Guid.CreateVersion7()` for GwTenantRoute and GwServiceInstance
+
+**Rationale:** String-based GUID IDs are more suitable for YARP route configuration and distributed service discovery scenarios. GwTenant retains `long` ID to maintain consistency with Platform's tenant management.
+

+
+## Requirements Mapping
+
+| Requirement | Status | Evidence |
+|-------------|--------|----------|
+| GATEWAY-01 | ✅ Partial | GwTenant entity created |
+| GATEWAY-02 | ✅ Partial | GwTenantRoute entity created |
+| GATEWAY-03 | ✅ Partial | GwServiceInstance entity created |
+
+> Note: Full requirement completion requires infrastructure layer (Store, Manager, DbContext) in subsequent plans.
+
+---
+
+## Next Steps
+
+- Plan 02: Infrastructure layer (Store, Manager, DbContext configurations)
+- Plan 03: Extensions and IoC integration
