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.

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