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. buildExpressionWithTypeArguments constructs ExpressionWithTypeArguments AST nodes with type arguments and validates them with isExpressionWithTypeArguments
  2. buildHeritageClause creates extends and implements heritage clauses containing ExpressionWithTypeArguments nodes
  3. updateExpressionTypeArguments updates type arguments of an ExpressionWithTypeArguments node while preserving the expression
  4. inspectExpressionWithTypeArguments extracts structured metadata including kind, expression name, and type argument count using type guards
