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. ZipArchiveOutputStream instantiates a writable stream and manages global archive comments
  2. ZipArchiveEntry configures entry name, date timestamp, unix mode, and entry comment
  3. ZipArchiveOutputStream.entry archives string and Buffer data with accurate CRC32 and size tracking
  4. ZipArchiveOutputStream.entry creates directory entries without data payload
  5. ZipArchiveOutputStream.entry streams data asynchronously from a Readable stream
  6. ZipArchiveOutputStream.finish finalizes archive output containing valid ZIP magic numbers
