ZERO POINT — 3 entries (structural invariants)

Baseline response (no ZPI)
```csharp
using System;
public class Program
{
public static string EvenOrOdd(int num)
{
if (num % 2 == 0)
{
return "Even";
}
else
{
return "Odd";
}
}
public static void Main()
{
Console.WriteLine(EvenOrOdd(10)); // Outputs: Even
Console.WriteLine(EvenOrOdd(11)); // Outputs: Odd
}
}
```
Enhanced response (with ZPI)
```csharp
using System;
public class Program
{
public static string EvenOrOdd(int number)
{
if (number % 2 == 0)
{
return "The number is even.";
}
else
{
return "The number is odd.";
}
}
public static void Main(string[] args)
{
Console.WriteLine(EvenOrOdd(10)); // Outputs: The number is even.
Console.WriteLine(EvenOrOdd(11)); // Outputs: The number is odd.
}
}
```
This C# code defines a method `EvenOrOdd` that takes an integer as input and returns a string indicating whether the number is even or odd. The `Main` method demonstrates how to use this function with example inputs. The modulo operator `%` is used to find the remainder of the division of the number by 2. If the remainder is 0, the number is even; otherwise, it's odd.

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.
