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
- SourceNode instantiates code chunks with line, column, source file, and optional identifier name
- SourceNode.add and SourceNode.prepend append and prepend string chunks or child SourceNodes
- SourceNode.walk traverses chunk nodes yielding code snippets and mapped source locations
- SourceNode.join combines chunks with a separator and SourceNode.replaceRight updates matching text
- SourceNode.toStringWithSourceMap generates merged code and a SourceMapGenerator with line and column mappings
- SourceNode.fromStringWithSourceMap reconstructs SourceNodes from generated code and a SourceMapConsumer
- SourceNode.setSourceContent and walkSourceContents manage original file source content
