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
- NumberFormat.currency formats with the three-letter ISO code unless simpleCurrency or an explicit symbol is used.
- NumberFormat.simpleCurrency parsing accepts both a symbol-prefixed value and the same localized number without its currency symbol.
- NumberFormat.simpleCurrency for JPY uses zero decimal places while currency with only an explicit yen symbol inherits the locale's decimal digits.
- NumberFormat.percentPattern multiplies by 100 and its locale pattern displays no fraction digits by default, while decimalPercentPattern can preserve them.
- NumberFormat.compactCurrency uses an ISO code while compactSimpleCurrency uses the currency symbol.
