NDLRGEN060: Constructor guard property does not participate in an overload

Cause

A property has [ConstructorGuard] or a constructor-guard alias without [RecordConstructorOverloadParameter].

Rule Description

Property guards are emitted only inside generated record constructor overloads. A guard does not trigger the overload by itself because that would make property participation implicit.

How to Fix

// WRONG
public partial record Request(string Name)
{
    [ConstructorGuard(ConstructorGuardKind.NotNull)]
    public string? Scope { get; init; }
}

// CORRECT
public partial record Request(string Name)
{
    [RecordConstructorOverloadParameter]
    [ConstructorGuard(ConstructorGuardKind.NotNull)]
    public string? Scope { get; init; }
}

Remove the guard instead when the property should remain outside the generated overload.
