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. subset returns true when the first range is completely contained within the second range
  2. subset returns false when the first range includes versions outside the second range
  3. intersects returns true when two version ranges share overlapping versions
  4. intersects returns false when two version ranges are completely disjoint
  5. subset and intersects support options like includePrerelease for prerelease range comparisons
