# 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`
- **Source**: SPRINT_0157_0001_0001_taskrunner_i.md

## 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
