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
- fromObject converts a source map object and returns new copy via toObject and JSON string via toJSON
- fromJSON parses a source map JSON string and allows modifying properties via getProperty, setProperty, and addProperty
- fromBase64 and toBase64 convert between base64-encoded strings and source map objects
- fromComment and toComment parse and format inline base64 and URI-encoded sourceMappingURL comments
- fromSource finds the last inline source map comment from source code or returns null if absent
- removeComments and removeMapFileComments strip inline data URIs and external map file comments from source text
- generateMapFileComment formats single-line and multi-line sourceMappingURL references to map files
- fromMapFileComment reads map file content using a custom reader function
