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
- validate verifies native Python data structures against Draft 2020-12 schemas.
- validate raises jsonschema.exceptions.ValidationError on schema constraint violations with accurate path and validator details.
- Draft202012Validator provides is_valid for boolean validation and iter_errors for collecting multiple validation errors.
- Draft202012Validator correctly evaluates Draft 2020-12 tuple and item validation keywords including prefixItems.
- FormatChecker supports registering custom format check functions via the checks decorator.
- Draft202012Validator.check_schema validates schema structures and raises SchemaError on invalid schemas.
