Analyze and document the existing gateway configuration broadcast mechanism. Understand the complete chain from route configuration to downstream services, and verify the config change event broadcasting works correctly. @.planning/phases/01-gateway-config-management/01-SUMMARY.md @.planning/phases/01-gateway-config-management/01-PLAN.md

Existing Implementation (from Phase 1)

The broadcast mechanism uses PostgreSQL NOTIFY:

• Channel: gateway_config_changed
• Event types: service, route, instance, gateway
• Actions: create, update, delete, reload
• Service: ConfigNotificationService.cs
• Integration: GatewayService.cs triggers broadcast on all CRUD operations

Task 1: Analyze existing broadcast implementation src/Services/ConfigNotificationService.cs, src/Services/GatewayService.cs Analyze the existing implementation to understand: 1. How ConfigNotificationService works (PostgreSQL NOTIFY) 2. How GatewayService triggers broadcasts on CRUD operations 3. What event types and payloads are sent

Read the source files and document the findings. Files exist and contain notification logic Implementation analysis complete, findings documented

Task 2: Map route -> service -> downstream flow Document the complete configuration chain: 1. How routes are defined in Console 2. How routes map to services 3. How services are discovered by downstream Gateway 4. When config changes, how the broadcast reaches downstream

Reference existing code in src/Models/, src/Services/, src/Controllers/ Flow documentation created Configuration chain documented

Task 3: Verify broadcast events work end-to-end Verify the broadcast mechanism: 1. Check if PostgreSQL LISTEN/NOTIFY is properly configured 2. Verify ReloadGatewayAsync sends the correct event 3. Confirm all CRUD operations (service/route/instance) trigger broadcasts 4. Test end-to-end flow if possible Build succeeds, API endpoints functional Broadcast verification complete 1. Read and analyze ConfigNotificationService.cs 2. Read and analyze GatewayService.cs 3. Document route -> service -> downstream flow 4. Verify build passes
