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
- parseAsync is exported as a function by @babel/core and returns a Promise resolving to a File AST node
- parseCodeAsync parses JavaScript source into an AST with Program body containing top-level statements
- parseModule parses ES module code with import and export declarations setting sourceType to module
- parseScript parses script code setting sourceType to script
- extractTopLevelDeclarations identifies top-level variable, function, and class declaration names from parsed AST
- isValidSyntax returns true for valid JavaScript code and false when parsing invalid syntax
- parseAsync rejects with a SyntaxError when given invalid JavaScript code
- parseWithParserOpts preserves tokens and ranges when enabled in parser options
