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
- packaging.version.Version parses semantic version strings and correctly evaluates version ordering precedence
- packaging.specifiers.SpecifierSet matches version instances against version specifier constraints and filters candidate lists
- packaging.requirements.Requirement parses package dependency requirements with extras and environment markers
