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. Buffer.compare returns 0 when two buffers contain identical byte sequences
  2. Buffer.compare returns -1 when first buffer sorts lexicographically before second buffer
  3. Buffer.compare returns 1 when first buffer sorts lexicographically after second buffer
  4. Buffer.compare orders shorter buffers before longer buffers when they share a common prefix
  5. Buffer.compare can be used as a comparator function to sort an array of Buffer instances in lexicographical order
  6. Buffer.prototype.compare compares buffer instances and supports optional target and source slice offsets
