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

Contract
- isPropertyDeclaration returns true for AST PropertyDeclaration nodes constructed with createPropertyDeclaration
- isPropertyDeclaration returns false for other AST node types such as Identifier, MethodDeclaration, and StringLiteral
- isPropertyDeclaration throws TypeError when evaluated on null or undefined
- filterPropertyDeclarations extracts and validates PropertyDeclaration nodes from class members using isPropertyDeclaration
- findPropertyDeclarationByName and validatePropertyDeclaration inspect PropertyDeclaration nodes and extract structural metadata
