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. fs.copy asynchronously copies a single file to a target destination, creating parent directories if needed
  2. fs.copy recursively copies an entire directory hierarchy preserving structure and content
  3. fs.copy supports a filter function to selectively copy files and directories
  4. fs.copy rejects with an error when overwrite is false and errorOnExist is true if destination exists
  5. fs.copySync synchronously copies directory structures and contents
  6. fs.copy preserves timestamps when preserveTimestamps option is true
