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. ZipEntry exposes getData method returning a Buffer of decompressed entry content
  2. getData returns byte-for-byte exact content matching original uncompressed data
  3. getData returns an empty Buffer for empty entries and directory entries
  4. getData successfully decompresses content from reloaded archive buffer
  5. getData preserves binary payload integrity across arbitrary byte sequences
  6. ZipEntry provides getDataAsync to retrieve entry data via a callback function
