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. AdmZip instance exposes writeZip method for persisting zip archives to disk
  2. writeZip synchronously writes archive to specified target file path
  3. writeZip creates target directories recursively if they do not exist
  4. writeZip supports optional callback for write completion notification
  5. writeZip overwrites original file when called without target path on an opened archive
  6. generated zip file on disk is readable by a new AdmZip instance and preserves entry contents
