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.
MIT-0

Contract
- Type-only default import from a JSON file in ESM NodeNext mode compiles with zero diagnostics in TypeScript 5.7.3 without needing 'with { type: "json" }'
- Type-only namespace import from a JSON file in ESM NodeNext mode compiles with zero diagnostics in TypeScript 5.7.3 and resolves exported types
