+# Router/Microservice SDK Solution Infrastructure
+
+## Module
+Router
+
+## Status
+IMPLEMENTED
+
+## Description
+Complete solution skeleton for the Router ecosystem including 17 library projects, 17 test projects, example applications, and Gateway WebService. Establishes the project structure for inter-service communication.
+
+## Implementation Details
+- **Modules**: `src/Router/`
+- **Key Projects**:
+  - `StellaOps.Gateway.WebService` - Gateway API service with routing middleware
+  - `StellaOps.Router.Common` - shared models, frame types, and transport abstractions
+  - `StellaOps.Router.Gateway` - gateway routing logic, state management, rate limiting
+  - `StellaOps.Router.Config` - YAML/JSON configuration with hot-reload
+  - `StellaOps.Microservice` - microservice SDK (endpoint discovery, connection, dispatch)
+  - `StellaOps.Microservice.SourceGen` - Roslyn source generator for AOT endpoints
+  - Transport plugins: `Router.Transport.InMemory`, `Router.Transport.Tcp`, `Router.Transport.Tls`, `Router.Transport.Udp`, `Router.Transport.RabbitMq`, `Router.Transport.Messaging`
+  - Messaging: `StellaOps.Messaging`, `Messaging.Transport.InMemory`, `Messaging.Transport.Postgres`, `Messaging.Transport.Valkey`
+  - `StellaOps.Router.Plugin.Unified` - unified plugin adapter system

+## E2E Test Plan
+- [ ] Build all 17 library projects and verify successful compilation
+- [ ] Run all 17 test project suites and verify they pass
+- [ ] Build and run the Gateway WebService and verify it starts and accepts connections
+- [ ] Build and run example applications and verify end-to-end communication through the Gateway
