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 provides AST builder functions to construct literal nodes such as identifier, numericLiteral, stringLiteral, booleanLiteral, and nullLiteral
- types provides AST builder functions to construct complex expression nodes including binaryExpression, unaryExpression, and callExpression
- types provides AST builder functions to construct statements and declarations including variableDeclaration, variableDeclarator, and functionDeclaration
- types provides type predicate functions such as isIdentifier, isNumericLiteral, isExpression, and isStatement with optional property matching
- types provides type assertion functions such as assertIdentifier and assertNumericLiteral that throw an error on type mismatch
- types provides AST utility functions such as cloneNode to create structural duplicates and isNodesEquivalent to verify structural equality
- types provides AST utility functions such as removeProperties to strip location metadata from AST nodes
