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
- semver parses, validates, sanitizes, and increments semantic version strings across major, minor, patch, and prerelease release types
- semver compares semantic version precedence with comparison predicates, sorting, and diff calculation
- semver evaluates version satisfaction against complex range expressions and selects minimum and maximum satisfying versions
- semver constructs SemVer and Range instances exposing structured version components and comparator sets
