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.

- mediaType selects the best match from an available list or returns undefined when none match
- languages and language determine client preferred languages by quality weight
- encodings and encoding determine supported compression algorithms from Accept-Encoding
- charsets and charset select preferred character encodings from Accept-Charset
