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
- db is an object mapping MIME type strings to metadata entries
- getType performs case-insensitive lookup and returns metadata entry with source, extensions, and charset
- getExtensions returns array of associated file extensions or empty array
- getDefaultExtension returns primary file extension without leading dot
- isCompressible returns boolean compressibility status of the media type
- findTypeByExtension looks up media type corresponding to a file extension
- getSource returns database origin source such as iana or apache
- getCharset returns defined charset encoding or undefined
