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
- @types/js-yaml package.json declares package version 4.0.9 and types entry point index.d.ts
- @types/js-yaml exports map exposes root types and ./package.json subpath
- @types/js-yaml index.d.ts declares State interface with version property typed as null | number
- inspectVersionDefinitions validates package version matching 4.0.9 and declaration structure
