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. import direct subpath functions from lodash-es requiring explicit .js extension
  2. import subpath modules using default import syntax because submodules only export default
  3. verify extensionless subpath imports fail with ERR_MODULE_NOT_FOUND in Node ESM
  4. verify submodule named exports do not exist on subpath files
  5. assert cloneDeep and merge perform deep cloning and merging correctly
