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. ast builders construct valid WebAssembly AST nodes including program, module, func, signature, instruction, and literals
  2. ast predicate functions correctly identify AST node types including isProgram, isModule, isFunc, isInstruction, and isValtypeLiteral
  3. cloneNode produces a deep clone of AST nodes preserving structure and properties
  4. traverse walks the AST and visits nodes by type selector
  5. traverse path operations support replacing, inserting, and removing AST nodes
