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. Comparator constructor parses operator and SemVer version from comparison strings
  2. Comparator test evaluates whether a version string or SemVer instance satisfies the comparison
  3. Comparator intersects determines whether two comparators have overlapping version ranges
  4. Comparator supports empty string comparators that match any version
  5. Comparator respects includePrerelease option for matching prerelease versions
  6. Comparator throws TypeError for invalid comparator expressions and test returns false for non-matching or invalid versions
