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. NodeHfs provides asynchronous file operations to write and read text and JSON files
  2. NodeHfs supports reading and writing raw byte arrays via Uint8Array
  3. NodeHfs accurately reports file and directory existence using isFile and isDirectory
  4. NodeHfs creates nested directories and lists directory contents as an async iterable of directory entries
  5. NodeHfs performs copy, move, and recursive delete operations on files and directory structures
  6. NodeHfs and NodeHfsImpl allow constructing custom filesystem instances backed by fs/promises
