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
- compile a JTD serializer with float64 property under default settings
- assert default serialization emits unquoted Infinity and NaN literals causing JSON.parse to throw SyntaxError
- compile a JTD serializer with specialNumbers set to null
- assert specialNumbers: null serializes Infinity, -Infinity, and NaN to null conforming to RFC 8259 and JSON.stringify
- assert finite numbers continue to serialize normally
