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
- Value.Cast preserves valid primitive, object, and array values that already conform to schema
- Value.Cast applies explicit default metadata on invalid or missing properties
- Value.Cast substitutes type-level default values when invalid primitive types are encountered without explicit default
- Value.Cast reconstructs missing or partially missing object properties while retaining conforming fields
- Value.Cast casts each item in an array to match the element schema
- Value.Cast falls back to the first union variant when a value does not match any union branch
- Value.Cast respects optional fields by keeping undefined when not provided in the input object
- Value.Check confirms that cast values satisfy schema validation
