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 findUp.exists returns a Promise resolving to true for an existing file
  2. assert findUp.exists returns a Promise resolving to false for a non-existent path
  3. assert findUp.exists returns a Promise resolving to true for an existing directory
  4. assert findUp.sync.exists returns true synchronously for an existing file
  5. assert findUp.sync.exists returns false synchronously for a non-existent path
  6. assert findUp.sync.exists returns true synchronously for an existing directory
  7. assert findUp.exists can be used within a custom findUp matcher function to locate existing target
