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
- NewSpanStartConfig resolves WithSpanKind, WithAttributes, WithNewRoot, WithTimestamp, and WithLinks into a SpanConfig
- NewSpanEndConfig and NewEventConfig record timestamps, attributes, and stack trace flags for span termination and events
- Tracer starts spans with configured start options, attaches spans to context via ContextWithSpan, and records events, errors, status, and attributes across the span lifecycle
- NoopTracerProvider and NoopTracer safely handle all start options, attributes, events, error records, and status updates as non-recording spans
