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
- acorn.Parser.extend(jsx()) parses JSXElement, JSXOpeningElement, and JSXClosingElement with boolean, string, and JSXExpressionContainer attributes
- acorn.Parser.extend(jsx()) parses JSXSpreadAttribute ({...props}) inside JSXOpeningElement attributes
- acorn.Parser.extend(jsx()) parses JSXFragment (<>...</>) and nested JSXMemberExpression (<UI.Header />, <UI.Body.Section />)
- acorn.Parser.extend(jsx()) parses and decodes named and numeric XML/HTML character entities in JSXText
- acorn.Parser.extend(jsx()) parses JSXExpressionContainer with JSXEmptyExpression ({/* comment */}) as child
- jsx({ allowNamespaces: true }) parses JSXNamespacedName on element tags and attributes, while allowNamespaces: false throws a SyntaxError on colons
- jsx({ allowNamespaces: true, allowNamespacedObjects: true }) parses JSXMemberExpression on namespaced objects (<svg:path.element />), while allowNamespacedObjects: false throws a SyntaxError
- acorn.Parser.extend(jsx()) throws a SyntaxError for mismatched JSX closing tags and unparented adjacent JSX elements
