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. tar.x extracts archive files asynchronously to a target directory and returns a Promise
  2. tar.x with sync option set to true extracts archive files synchronously
  3. tar.x returns a writable stream to parse and unpack tar streams when file option is omitted
  4. tar.x filters extracted archive entries using a predicate function passed to the filter option
  5. tar.x strips leading path components from extracted files using the strip option
