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
- dump serializes JavaScript objects, arrays, and primitives into standard YAML format
- dump supports custom indent widths for nested objects
- dump sorts dictionary keys alphabetically when sortKeys is true
- dump formats collections in inline flow style when flowLevel is configured
- dump enforces explicit double or single quotes around strings with forceQuotes and quotingType
- dump omits non-serializable values such as functions without throwing when skipInvalid is true
- dump duplicates repeated object references instead of generating anchors when noRefs is true
