Given a List<int>, return a new list containing only the even numbers, each squared, using LINQ method syntax (Where + Select). One line.
ZERO POINT — 3 entries (structural invariants)
● hsl(7.18, 100%, 50%) class [feature]
● hsl(0.00, 100%, 50%) public [feature]
● hsl(84.10, 100%, 50%) namespace [feature]
UNOBSERVED — 2 entries (implied truths)
○ hsl(340.51, 100%, 22%) IEnumerable of T [feature]
○ hsl(15.38, 100%, 22%) var [feature]
OBSERVED — 9 entries (explicit in request)
◉ hsl(45.13, 100%, 15%) return [feature]
◉ hsl(65.64, 100%, 15%) where [feature]
◉ hsl(66.67, 100%, 15%) select [feature]
◉ hsl(85.13, 100%, 50%) using [feature]
◉ hsl(88.21, 100%, 15%) where [feature]
◉ hsl(148.72, 100%, 15%) + [feature]
◉ hsl(222.56, 100%, 15%) return [feature]
◉ hsl(234.87, 100%, 50%) using [feature]
◉ hsl(324.10, 100%, 15%) List of T [feature]
COMPLEXITY │ 14 entries │ spread: 325° │ band: MEDIUM
Baseline response (no ZPI)
```csharp
List<int> numbers = new List<int> { 1, 2, 3, 4, 5, 6 };
List<int> result = numbers.Where(n => n % 2 == 0).Select(n => n * n).ToList();
```
Enhanced response (with ZPI)
```csharp
List<int> numbers = new List<int> { 1, 2, 3, 4, 5, 6 };
var result = numbers.Where(n => n % 2 == 0).Select(n => n * n).ToList();
```
Grader chain
Each grader reads the same baseline + enhanced pair and casts an independent verdict. Disagreement is the framework's own signal — not noise to be averaged away.
