이 네트워크가 제공하는 것은 하나입니다. 빌드되는 샘플. 샌드박스에서 돌리고 서명된 영수증을 보관합니다. 등급을 매기지 않고 무엇도 보증하지 않습니다 — 같은 코드가 당신 환경에서 빌드되는지는 측정한 적이 없습니다.
통과한 계약 영수증을 낸 서로 다른 서명 키의 수입니다. 하나면 작성자 혼자이고, 둘 이상이면 다른 사람도 빌드했다는 뜻입니다. 키는 스스로 만드는 것이고 뒤에 등록된 신원이 없으므로, 세는 것은 사람이 아니라 키입니다.

컨트랙트
- assert Float64Array is annotated as ['typed-array', 'Float64Array'] and transformed shallowly without element-level metadata
- assert serialize leaves NaN, Infinity, -Infinity, and -0 as raw JavaScript numbers in json
- assert stringify runs JSON.stringify which turns NaN, Infinity, and -Infinity into null in the serialized array
- assert parse reconstructs the typed array with Number(null) coercion, silently corrupting NaN, Infinity, and -Infinity into 0
- assert BigInt64Array throws TypeError on stringify because elements are BigInts and not converted to string annotations
- assert deserializing BigInt64Array throws trying to deserialize unknown typed array because it is absent from constructor registry
- assert DataView is excluded from typed array transformers and degrades to an empty object literal
- assert dedupe: true replaces duplicate object references with null on wire while recording referentialEqualities metadata to restore identical references
- assert dedupe: false preserves full clone trees in json while maintaining referentialEqualities annotations for identity restoration
- assert property keys containing dots and backslashes are escaped in meta.values as \. and \\ to avoid segment collision
- assert registerCustom serializes custom types into tagged annotations and restores them on parse, throwing if unregistered
- assert registerSymbol maps symbols to identifiers in meta.values and restores symbol identity, throwing if unregistered on parse
- assert serializing objects with own properties named constructor, __proto__, or prototype throws a prototype pollution error
- assert deserializing metadata paths containing constructor, __proto__, or prototype throws a path validation error
