# Project State

**Last Updated:** 2026-03-03

## Status

- **Phase:** 03-gateway-infrastructure-update
- **Plan:** 03 ✅ Completed
- **Milestone:** v1.0 - Platform Foundation
- **Position:** Completed Plan 03 of Phase 03

## Project Context

This is the Fengling.Platform project - a multi-tenant identity and authentication infrastructure.

### Current State

- Platform layer initialized with Tenant, User, Role aggregates
- **GatewayAggregate updated** - GwTenantRoute extended, GwTenant and GwServiceInstance removed
- **NEW: GwCluster aggregate** added with embedded value objects (GwDestination, GwHealthCheckConfig, GwSessionAffinityConfig)
- **NEW: IClusterStore/ClusterStore** - Store pattern for GwCluster
- Manager + Store pattern established (ITenantStore, ITenantManager, IRouteStore, IClusterStore)
- Extensions for DI registration (AddPlatformCore<TContext>, AddGatewayCore<TContext>)
- PostgreSQL database with EF Core migrations

### Source for Migration

**fengling-gateway** project (parent directory):
- `GwTenant` - 租户实体 (REMOVED - use Platform.Tenant)
- `GwTenantRoute` - 路由配置实体 (EXTENDED)
- `GwServiceInstance` - 服务实例实体 (REMOVED - use GwCluster embedded)
- `GwCluster` - 集群聚合根 (NEW)
- GatewayDbContext with PostgreSQL

## Decisions

- Using Manager + Store pattern from existing Tenant implementation
- Extensions-based DI registration for quick IoC setup
- Align with existing Platform coding conventions
- **ID Strategy:** GwTenant uses `long` ID (Platform convention); GwTenantRoute, GwCluster use `string` GUID IDs (YARP-compatible)
- **Cluster Design:** GwCluster uses embedded value objects (Owned Entity pattern) for Destinations, HealthCheck, SessionAffinity
- **Route Update:** Extended GwTenantRoute with Methods, Hosts, Headers, LoadBalancingPolicy, AuthorizationPolicy, CorsPolicy, Transforms fields

## Blockers

None.
