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
- SourceMapGenerator constructor creates an instance configured with optional file and sourceRoot
- addMapping adds line and column mappings between generated code and original source positions
- setSourceContent embeds raw source file contents directly into the source map
- toJSON produces a valid V3 source map object with version, file, sources, names, mappings, and sourcesContent
- toString serializes the source map object to a valid JSON string
- fromSourceMap static method creates a new SourceMapGenerator initialized from an existing SourceMapConsumer
