# Phase 03: Gateway Cluster Entities Verification Report

**Phase Goal:** Restructure gateway cluster management - replace GwServiceInstance with GwCluster aggregate root
**Verified:** 2026-03-03
**Status:** passed
**Re-verification:** No - initial verification

## Goal Achievement

### Observable Truths

| # | Truth | Status | Evidence |
|---|-------|--------|----------|
| 1 | GwCluster uses string Id (GUID) | ✓ VERIFIED | GwCluster.cs line 8: `Id { get; set; } = Guid.CreateVersion7().ToString("N")` |
| 2 | GwDestination as Owned Entity embedded | ✓ VERIFIED | GwCluster.cs line 28: `List<GwDestination> Destinations` + PlatformDbContext.cs lines 114-122 |
| 3 | Value objects use Owned Entity configuration | ✓ VERIFIED | PlatformDbContext.cs lines 125-136: OwnsOne configs for HealthCheck and SessionAffinity |
| 4 | GwTenantRoute extended with Methods, Hosts, Headers, Transforms | ✓ VERIFIED | GwTenantRoute.cs lines 75-114: new fields added |
| 5 | Old entities GwTenant and GwServiceInstance removed | ✓ VERIFIED | grep shows no matches for these files |
| 6 | PlatformDbContext contains GwCluster DbSet | ✓ VERIFIED | PlatformDbContext.cs line 22: `public DbSet<GwCluster> GwClusters` |
| 7 | IClusterStore replaces IInstanceStore | ✓ VERIFIED | IClusterStore.cs exists, grep shows no IInstanceStore references |

**Score:** 7/7 truths verified

| GATEWAY-RESTRUCTURE-07 | 03-gateway-di-update | DI registration | ✓ SATISFIED | Extensions.cs updated |

**Note:** REQUIREMENTS.md does not exist in .planning/ directory, but all requirement IDs from PLAN frontmatter are verified.

### Anti-Patterns Found

| File | Line | Pattern | Severity | Impact |
|------|------|---------|----------|--------|
| None | - | - | - | - |

### Build Verification

- ✓ Fengling.Platform.Domain: 0 errors, 1 warning
- ✓ Fengling.Platform.Infrastructure: 0 errors, 2 warnings

### Human Verification Required

None - all checks are automated and verified.

### Summary

**All must-haves verified.** Phase goal achieved:

1. **GwCluster aggregate root** created with GUID-based string Id, embedded Destinations, HealthCheck, and SessionAffinity
2. **Value objects** properly configured as Owned Entities in EF Core
3. **GwTenantRoute** extended with YARP routing fields (Methods, Hosts, Headers, LoadBalancingPolicy, AuthorizationPolicy, CorsPolicy, Transforms)
4. **Obsolete entities** (GwTenant, GwServiceInstance) removed from Domain layer
5. **Infrastructure** updated with IClusterStore/ClusterStore, old IInstanceStore/InstanceStore deleted
6. **DI registration** updated in both Extensions.cs and GatewayExtensions.cs

The gateway cluster management has been successfully restructured to replace GwServiceInstance with GwCluster aggregate root.
