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
- cpuid.CPU is a global CPUInfo struct initialized at startup providing non-negative core counts and matching vendor information.
- cpuid.CPU.Supports returns true if all specified feature IDs are supported, and cpuid.CPU.AnyOf returns true if at least one feature ID is supported.
- Passing cpuid.UNKNOWN (-1) or an unrecognized feature ID directly to cpuid.CPU.Has causes an index out of range panic.
- Dynamic feature flag modification with Enable and Disable updates CPUInfo feature membership and alters subsequent Has, Supports, and AnyOf query results.
