## ADDED Requirements
### Requirement: Parametric Sweep and Design-of-Experiments Engine
The system SHALL provide batch parametric sweep and DOE orchestration with structured experiment manifests and reproducible runs as a first-class, deterministic feature suitable for production power-electronics workflows.

#### Scenario: DOE manifest runs multi-parameter batch and aggregates metrics
- **GIVEN** a valid model configured for batch parametric sweep and DOE orchestration with structured experiment manifests and reproducible runs
- **WHEN** the feature is executed
- **THEN** the backend completes with deterministic outputs and typed telemetry
- **AND** results are exportable through existing result channels/APIs.

#### Scenario: Invalid DOE manifest schema is rejected before execution
- **GIVEN** an invalid or unsupported configuration for batch parametric sweep and DOE orchestration with structured experiment manifests and reproducible runs
- **WHEN** the run is validated or executed
- **THEN** execution fails fast with structured, deterministic diagnostics
- **AND** partial/ambiguous outputs are not emitted.
