## Description

Generate Euro NCAP test scenarios and variants using the  ADT Euro NCAP support package. Use when creating NCAP seed scenarios, generating variants, translating between drivingScenario and RoadRunner, plotting scenario descriptors, computing NCAP scores, or exporting reports. Triggers on: ncapScenario, euroAssessment, getScenario, getScenarioDescriptor, generateVariants, ScenarioDescriptor, ScenarioDescriptorPlot, ncapScore, ncapReport, exportReport, configureVUT, assessmentTable, Euro NCAP, CCRs, CCRm, CCRb, CCFtap, CCCscp, CPNA, CPFA, CBNA, variant generation.

# Generate Euro NCAP Variants

Create Euro NCAP seed scenarios, generate variants, translate between simulators, plot descriptors, and compute scores using the ADT Euro NCAP support package APIs.

## When to Use

- Creating Euro NCAP seed scenarios (any protocol year)
- Generating scenario variants from seeds
- Translating scenarios between drivingScenario and RoadRunner via descriptors
- Plotting scenario descriptors (single or multi-descriptor grids)
- Computing NCAP scores and generating/exporting reports
- Any workflow mentioning Euro NCAP test names (CCRs, CCFtap, CCCscp, CPNA, etc.)

## When NOT to Use

- Building custom drivingScenario from scratch (roads, lanes, actors), use drivingScenario core APIs directly
- RoadRunner scene/project management (creating projects, importing assets), use RoadRunner scene APIs
- Custom `variationProperties` for non-NCAP scenarios
- Simulink co-simulation or AEB test bench setup

## Decision Tree: Which API Path?

```
User wants Euro NCAP scenarios?
│
├─ Protocol year 2023 (or unspecified)?
│   └─ Use standalone: ncapScenario("SA AEB CCFtap")
│      - Test names use prefix: "SA AEB", "SA LSS", "VRU AEB", "VRU LSS"
│      - Supports ShowProgress name-value
│      - Returns ScenarioDescriptor
│
└─ Protocol year 2026?
    └─ Use euroAssessment path:
       1. ea = euroAssessment(2026)
       2. configureVUT(ea, ...), if custom VUT needed
       3. descriptor = ncapScenario(ea, "CA FC CCFtap")
       - Test names use prefix: "CA FC"
       - Does NOT support ShowProgress
       - Required for scoring/reporting workflow
```
