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
- assert CalculatorRegistry auto-detects available arithmetic backend without manual configuration
- assert explicit CalculatorRegistry::set with NativeCalculator forces pure-PHP calculation engine
- assert NativeCalculator executes arbitrary-precision addition, multiplication, and division without C extensions
- assert BigDecimal delegates mathematical operations through active CalculatorRegistry backend
- assert explicit configuration of missing GMP backend throws fatal engine Error instead of MathException on calculation
- assert CalculatorRegistry::set with null restores automatic environment backend detection
