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.

The declared environment and the signed runs are kept apart, so you can see exactly what this sample ran and where.

Contract
- cpuid.Flags registers command-line flags including cpu.arm, cpu.disable, and cpu.features for runtime CPU feature configuration.
- cpuid.CPU is an exported global CPUInfo struct initialized at startup providing non-negative physical and logical core counts and vendor metadata.
- cpuid.FeatureID represents hardware CPU features, providing String representation, ParseFeature lookup, and UNKNOWN for unrecognized strings.
- cpuid.Detect re-evaluates hardware CPU features, resetting any dynamically modified flags on the global cpuid.CPU instance.
- cpuid.CPU.Supports returns true if all specified feature IDs are supported (vacuously true for zero args), and cpuid.CPU.AnyOf returns true if at least one is supported.
