# Roslyn Endpoint Source Generator (AOT-Compatible)

## Module
Router

## Status
IMPLEMENTED

## Description
Roslyn incremental source generator that detects `[StellaEndpoint]` attributes at compile time and generates AOT-compatible endpoint registration code, eliminating runtime reflection for endpoint discovery. Supports Native AOT deployment scenarios.

## Implementation Details
- **Modules**: `src/Router/__Libraries/StellaOps.Microservice.SourceGen/`
- **Key Classes**:
  - `StellaEndpointGenerator` (`src/Router/__Libraries/StellaOps.Microservice.SourceGen/StellaEndpointGenerator.cs`) - Roslyn incremental source generator detecting `[StellaEndpoint]` attributes and generating `StellaEndpoints` registration class
- **Interfaces**: `IIncrementalGenerator` (Roslyn API)
- **Source**: batch_52/file_10.md

## E2E Test Plan
- [ ] Compile a project with `[StellaEndpoint]` attributes and verify the source generator produces registration code
- [ ] Verify generated code is AOT-compatible: publish with Native AOT and confirm endpoints are discoverable without reflection
- [ ] Verify the generated `StellaEndpoints` class registers all annotated endpoints
- [ ] Add a new `[StellaEndpoint]` and verify incremental generation updates the output
- [ ] Verify compile-time diagnostics: use invalid attribute parameters and confirm helpful error messages
