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. buildInterfaceDeclaration constructs an interface declaration AST node with property and method signatures and validates it with isInterfaceDeclaration
  2. buildGenericInterfaceDeclaration constructs an interface declaration with type parameters and extends heritage clause
  3. buildPropertySignature constructs property signatures with optional modifiers and question token
  4. inspectInterfaceDeclaration extracts interface metadata including name, modifiers, type parameters, heritage clauses, and member descriptors
