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

Execution evidence

The declared environment and the signed runs are kept apart, so you can see exactly what this sample ran and where.

Contract

  1. assert requiresQuoting identifies identifier strings requiring quotes versus valid unquoted names
  2. assert typeOrValueSpecifiersSchema and readonlynessOptionsDefaults provide expected schemas and defaults
  3. assert isNullableType detects types containing null or undefined in union and primitive types
  4. assert getTypeFlags and isTypeFlagSet evaluate TypeScript TypeFlags on type instances
  5. assert isTypeArrayTypeOrUnionOfArrayTypes detects array types and union of array types
  6. assert isTypeAnyType, isTypeUnknownType, and isTypeNeverType identify any, unknown, and never types
  7. assert isTypeBigIntLiteralType and isTypeTemplateLiteralType identify bigint and template literal types
  8. assert isPromiseLike and isErrorLike identify Promise and Error objects
  9. assert isTypeReadonly differentiates readonly and mutable object structures
  10. assert discriminateAnyType categorizes types into AnyType enum variants
