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. otel.GetMeterProvider returns default non-nil MeterProvider and otel.SetMeterProvider updates the global MeterProvider
  2. otel.Meter creates named Meter with options to construct synchronous (Int64Counter, Int64UpDownCounter, Float64Histogram) and asynchronous (Int64ObservableGauge) instruments
  3. otel.GetTracerProvider returns default non-nil TracerProvider and otel.SetTracerProvider updates the global TracerProvider
  4. otel.Tracer creates named Tracer capable of starting spans, adding events, and recording errors
  5. otel.SetErrorHandler registers ErrorHandlerFunc to handle errors dispatched via otel.Handle safely and concurrently
  6. otel.GetTextMapPropagator and otel.SetTextMapPropagator manage global composite text map propagators
