+# TaskRunner SDK Client with OpenAPI
+
+## Module
+TaskRunner
+
+## Status
+IMPLEMENTED
+
+## Description
+Auto-generated SDK client for TaskRunner APIs with OpenAPI spec, deprecation middleware, and versioned endpoint support for external integrators.
+
+## Implementation Details
+- **Client interface**: `src/TaskRunner/StellaOps.TaskRunner/StellaOps.TaskRunner.Client/ITaskRunnerClient.cs` -- SDK client contract
+- **Client implementation**: `src/TaskRunner/StellaOps.TaskRunner/StellaOps.TaskRunner.Client/TaskRunnerClient.cs` -- HTTP client for TaskRunner APIs
+- **Client options**: `src/TaskRunner/StellaOps.TaskRunner/StellaOps.TaskRunner.Client/TaskRunnerClientOptions.cs` -- configurable client options
+- **DI extensions**: `src/TaskRunner/StellaOps.TaskRunner/StellaOps.TaskRunner.Client/Extensions/TaskRunnerClientServiceCollectionExtensions.cs` -- DI registration
+- **Pack run models**: `src/TaskRunner/StellaOps.TaskRunner/StellaOps.TaskRunner.Client/Models/PackRunModels.cs` -- client-side pack run models
+- **Lifecycle helper**: `src/TaskRunner/StellaOps.TaskRunner/StellaOps.TaskRunner.Client/Lifecycle/PackRunLifecycleHelper.cs` -- pack run lifecycle management
+- **Pagination**: `src/TaskRunner/StellaOps.TaskRunner/StellaOps.TaskRunner.Client/Pagination/Paginator.cs` -- paginated API result handling
+- **Streaming log reader**: `src/TaskRunner/StellaOps.TaskRunner/StellaOps.TaskRunner.Client/Streaming/StreamingLogReader.cs` -- real-time log streaming
+- **OpenAPI metadata**: `src/TaskRunner/StellaOps.TaskRunner/StellaOps.TaskRunner.WebService/OpenApiMetadataFactory.cs` -- OpenAPI spec generation
+- **Deprecation middleware**: `src/TaskRunner/StellaOps.TaskRunner/StellaOps.TaskRunner.WebService/Deprecation/ApiDeprecationMiddleware.cs`, `ApiDeprecationOptions.cs`, `IDeprecationNotificationService.cs` -- API versioning and deprecation support
+- **WebService program**: `src/TaskRunner/StellaOps.TaskRunner/StellaOps.TaskRunner.WebService/Program.cs` -- API host with OpenAPI endpoints
+- **Tests**: `src/TaskRunner/StellaOps.TaskRunner/StellaOps.TaskRunner.Tests/TaskRunnerClientTests.cs`, `OpenApiMetadataFactoryTests.cs`, `ApiDeprecationTests.cs`

+## E2E Test Plan
+- [ ] Verify SDK client can list, create, and manage pack runs
+- [ ] Test streaming log reader receives real-time execution logs
+- [ ] Verify OpenAPI spec is generated and accessible at /swagger endpoint
+- [ ] Test deprecation middleware returns correct headers for deprecated endpoints
+- [ ] Verify pagination handles large result sets correctly
