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
- MeterProvider creates Meter instances with instrumentation configuration
- Meter creates Int64Counter, Int64UpDownCounter, and Float64Histogram instruments
- Int64Counter records non-negative metric measurements with attributes
- Int64UpDownCounter records bi-directional gauge adjustments
- Float64Histogram records duration measurements with explicit units and bucket boundaries
