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. assert getPackageType asynchronously resolves to "module" for a file inside a package with type module
  2. assert getPackageType asynchronously resolves to "commonjs" for a file inside a package with type commonjs
  3. assert getPackageType asynchronously resolves to "commonjs" for a file inside a package without explicit type field
  4. assert getPackageType asynchronously resolves to "commonjs" when no package.json exists in directory hierarchy
  5. assert getPackageType asynchronously stops at node_modules boundary and returns "commonjs" ignoring parent type module
  6. assert getPackageType.sync synchronously returns "module" for a file inside a package with type module
  7. assert getPackageType.sync synchronously returns "commonjs" for a file inside a package with type commonjs
  8. assert getPackageType.sync synchronously returns "commonjs" for a file inside a package without explicit type field
  9. assert getPackageType.sync synchronously resolves nested module package inside node_modules
  10. assert getPackageType.sync synchronously returns "module" when searching from nested subdirectories up to package.json
