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 generates v3 source map with mappings and embedded sourcesContent
- SourceMapConsumer resolves originalPositionFor with mapped line column and symbol name
- SourceMapConsumer resolves generatedPositionFor matching original line and column
- SourceMapConsumer retrieves original source code via sourceContentFor
