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. atLeastNode is a callable function accepting a target version string
  2. returns true when current node version is greater than the required major version
  3. returns true when current node version equals the required version string
  4. returns false when current node version is less than the required major version
  5. handles semantic version strings with major minor and patch numbers correctly
  6. helper function checks minimum version requirement for runtime feature gating
