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
- getVersion returns the current Jest core version string 29.7.0
- runCLI executes test suites programmatically and returns success status with passed test counts
- runCLI returns failure status when test assertions fail
- runCLI passes with no tests when passWithNoTests is true
- runCLI returns globalConfig and results object in returned object
