Prompt
Use EXISTS to find customers with at least one cancelled order.
Zero-point index (what the engine surfaced)
ZPI-ZPI-0020 | 2026-05-10T17:57:10Z
Use EXISTS to find customers with at least one cancelled order.
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 — 0 entries (implied truths)
OBSERVED — 1 entries (explicit in request)
◉ hsl(98.46, 100%, 50%) with [feature]
COMPLEXITY │ 4 entries │ spread: 0° │ band: LOW
Baseline response (no ZPI)
```csharp
using System;
using System.Data;
using System.Data.SqlClient;
class Program
{
static void Main()
{
// Create a connection to the database
string connectionString = "Server=myServerAddress;Database=myDataBase;User Id=myUsername;Password=myPassword;";
SqlConnection connection = new SqlConnection(connectionString);
// Create a query
string query = @"
SELECT c.CustomerName
FROM Customers c
WHERE EXISTS (
SELECT 1
FROM Orders o
WHERE o.CustomerID = c.CustomerID AND o.OrderStatus = 'Cancelled'
)
";
// Create a command
SqlCommand command = new SqlCommand(query, connection);
// Open the connection
connection.Open();
// Execute the query and read the results
SqlDataReader reader = command.ExecuteReader();
while (reader.Read())
{
Console.WriteLine(reader["CustomerName"]);
}
// Close the reader and connection
reader.Close();
connection.Close();
}
}
```
Enhanced response (with ZPI)
```csharp
using System;
using System.Data.SqlClient;
class Program
{
static void Main()
{
string connectionString = "Server=myServerAddress;Database=myDataBase;User Id=myUsername;Password=myPassword;";
string query = @"
SELECT c.CustomerID, c.CustomerName
FROM Customers c
WHERE EXISTS (
SELECT 1
FROM Orders o
WHERE o.CustomerID = c.CustomerID AND o.Status = 'Cancelled'
)
";
using (SqlConnection connection = new SqlConnection(connectionString))
{
connection.Open();
SqlCommand command = new SqlCommand(query, connection);
SqlDataReader reader = command.ExecuteReader();
while (reader.Read())
{
Console.WriteLine($"Customer ID: {reader["CustomerID"]}, Customer Name: {reader["CustomerName"]}");
}
}
}
}

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.
