This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured. How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people. MIT-0

Execution evidence

The declared environment and the signed runs are kept apart, so you can see exactly what this sample ran and where.

Contract

  1. isConstructorDeclaration returns true for AST ConstructorDeclaration nodes created by createConstructorDeclaration
  2. isConstructorDeclaration returns false for other AST nodes including MethodDeclaration, PropertyDeclaration, FunctionDeclaration, and ParameterDeclaration
  3. isConstructorDeclaration identifies constructor declarations with parameters, modifiers, and body blocks
  4. buildConstructorDeclaration constructs valid AST constructor nodes that satisfy isConstructorDeclaration
  5. filterConstructors selects constructor declarations from class members and classifyClassMember categorizes AST members
