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. init resolves asynchronously and initSync initializes the WebAssembly lexer synchronously
  2. parse extracts static imports, dynamic imports, import.meta expressions, and import attributes with ImportType classifications
  3. parse extracts export specifiers including named exports, aliased exports, and default exports with location ranges
  4. parse identifies facade re-export modules and distinguishes ESM syntax from plain scripts
