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. Client instance starts in closed state and respects configured timeout parameter
  2. trackProgress allows setting and clearing progress handlers on Client
  3. access establishes FTP connection and authenticates with credentials
  4. pwd returns current working directory path
  5. cd and cdup navigate remote working directories
  6. send executes FTP commands and returns response object
  7. server failure responses reject with FTPError instance and status code
  8. close closes connection and resets closed state to true
