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
