## ADDED Requirements
### Requirement: Parallel Batch Simulation Engine
The system SHALL provide parallel execution of independent simulations/analyses with deterministic aggregation and reproducible ordering as a first-class, deterministic feature suitable for production power-electronics workflows.

#### Scenario: Parallel campaign execution preserves deterministic result ordering
- **GIVEN** a valid model configured for parallel execution of independent simulations/analyses with deterministic aggregation and reproducible ordering
- **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: Resource/thread configuration violations are validated deterministically
- **GIVEN** an invalid or unsupported configuration for parallel execution of independent simulations/analyses with deterministic aggregation and reproducible ordering
- **WHEN** the run is validated or executed
- **THEN** execution fails fast with structured, deterministic diagnostics
- **AND** partial/ambiguous outputs are not emitted.
