# Export Job Service

## Module
Orchestrator

## Status
IMPLEMENTED

## Description
Export job management with service and domain model for orchestrated export operations.

## Implementation Details
- **Modules**: `src/JobEngine/StellaOps.JobEngine/StellaOps.JobEngine.Core/Services/`, `src/JobEngine/StellaOps.JobEngine/StellaOps.JobEngine.Core/Domain/Export/`
- **Key Classes**:
  - `ExportJobService` (`src/JobEngine/StellaOps.JobEngine/StellaOps.JobEngine.Core/Services/ExportJobService.cs`) - manages export job lifecycle: creation, scheduling, execution tracking, and completion
  - `ExportJob` (`src/JobEngine/StellaOps.JobEngine/StellaOps.JobEngine.Core/Domain/Export/ExportJob.cs`) - export job entity with status, target, format, and schedule
  - `ExportJobPolicy` (`src/JobEngine/StellaOps.JobEngine/StellaOps.JobEngine.Core/Domain/Export/ExportJobPolicy.cs`) - policy controlling export permissions and constraints
  - `ExportJobTypes` (`src/JobEngine/StellaOps.JobEngine/StellaOps.JobEngine.Core/Domain/Export/ExportJobTypes.cs`) - enumeration of supported export types (evidence pack, audit report, snapshot)
  - `ExportSchedule` (`src/JobEngine/StellaOps.JobEngine/StellaOps.JobEngine.Core/Domain/Export/ExportSchedule.cs`) - scheduling configuration for recurring exports
  - `LedgerExporter` (`src/JobEngine/StellaOps.JobEngine/StellaOps.JobEngine.Infrastructure/Ledger/LedgerExporter.cs`) - exports audit ledger data for compliance and audit
  - `ExportJobEndpoints` (`src/JobEngine/StellaOps.JobEngine/StellaOps.JobEngine.WebService/Endpoints/ExportJobEndpoints.cs`) - REST API for creating, querying, and managing export jobs
- **Interfaces**: `ILedgerExporter` (`src/JobEngine/StellaOps.JobEngine/StellaOps.JobEngine.Infrastructure/Ledger/ILedgerExporter.cs`)
- **Source**: Feature matrix scan

## E2E Test Plan
- [ ] Create an export job via `ExportJobEndpoints` with type=evidence_pack and verify it is persisted with status=Pending
- [ ] Execute the export job via `ExportJobService` and verify status transitions: Pending -> Running -> Completed
- [ ] Verify export policy enforcement: create an export job with a restricted type and verify `ExportJobPolicy` rejects it
- [ ] Schedule a recurring export via `ExportSchedule` and verify the next execution is computed correctly
- [ ] Export audit ledger data via `LedgerExporter` and verify the output contains all entries within the specified time range
- [ ] Create an export job with retention policy and verify completed exports are cleaned up after expiry
- [ ] Query export jobs via `ExportJobEndpoints` with status filter and verify pagination works correctly
- [ ] Test export failure: simulate an export error and verify the job transitions to Failed with error details
