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. Resolving a canonical file path with realpathSync returns the resolved absolute path
  2. Resolving a symlink with realpathSync resolves the symlink target path
  3. Resolving a symlink asynchronously with realpath passes the resolved path to the callback
  4. Resolving a non-existent path with realpathSync throws an ENOENT error
  5. Resolving a non-existent path with realpath passes an ENOENT error to the callback
  6. Calling monkeypatch replaces fs.realpath and fs.realpathSync with package implementations, and unmonkeypatch restores them
