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. MIT-0

Execution evidence

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

Contract

  1. MetricDescriptor struct fields and getter methods return configured attributes including Name, Type, MetricKind, ValueType, Unit, Description, DisplayName, Labels, and MonitoredResourceTypes
  2. Nil safety — GetName, GetType, GetUnit, GetDescription, GetDisplayName, GetMetricKind, GetValueType, GetLabels, GetMetadata, and GetMonitoredResourceTypes on nil *MetricDescriptor return zero values without panicking
  3. Protobuf binary serialization and deserialization preserves MetricDescriptor fields exactly
  4. Protobuf JSON serialization and deserialization preserves MetricDescriptor structure and values
  5. Nested LabelDescriptor within MetricDescriptor correctly specifies label schema
  6. Reset clears MetricDescriptor fields back to zero default values
