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
- BigNumber::of("123\n") throws NumberFormatException rather than accepting trailing newline
- BigInteger::of("456\n") throws NumberFormatException rather than accepting trailing newline
- BigDecimal::of("123.45\n") throws NumberFormatException rather than accepting trailing newline
- BigRational::of("3/4\n") throws NumberFormatException rather than accepting trailing newline
- BigDecimal::of('1e9999999999999999999999') throws NumberFormatException rather than IntegerOverflowException
- BigInteger::fromBase('12Z', 10) throws NumberFormatException quoting original uppercase character 'Z'
- Trimmed numeric strings without trailing newlines parse into BigNumber, BigInteger, BigDecimal, and BigRational instances
