# 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
- **Source**: batch_51/file_15.md

## 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
