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
- assert unwired tracer creates non-recording spans with invalid zero IDs
- assert active wired span is recording with valid non-zero trace ID and span ID
- assert ended span IsRecording returns false per specification
- assert syncer exporter contains span immediately after span.End()
- assert batch exporter contains zero spans after span.End() until ForceFlush or Shutdown is called
