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. semver.lte returns true when the first version is strictly less than or equal to the second version
  2. semver.lte returns false when the first version is strictly greater than the second version
  3. semver.lte compares prerelease versions lower than the corresponding normal release version
  4. semver.lte ignores build metadata when evaluating version precedence
  5. semver.lte handles formatted version strings with prefixes, whitespace, and loose options
