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
- Type.Object constructs valid JSON Schema with expected properties and required constraints
- TypeCompiler.Compile creates compiled validator that returns true for valid payloads and false for invalid structures
- TypeCompiler validator Errors iterator yields validation error details for invalid data
- Value.Check validates arbitrary JavaScript values against TypeBox schema definitions
- Value.Create generates default instance structures populated from schema default metadata
