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
- types creates literal AST nodes (stringLiteral, numericLiteral, booleanLiteral, nullLiteral) with expected AST structure
- types constructs variable declarations with identifiers and initializers using variableDeclaration and variableDeclarator
- types builds binary operator expressions and verifies operand expression types
- types builds call expressions and validates expression nodes with isCallExpression and isExpression
- types constructs function declarations with identifier parameters and block statements
- types provides type checking helpers including isIdentifier, isBinaryExpression, isExpression, and isStatement
- types clones AST nodes deeply with cloneNode and verifies structural equivalence with isNodesEquivalent
- types asserts identifier node types with assertIdentifier and throws an error for non-identifier nodes
