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 default global TextMapPropagator has 0 fields and silently no-ops on Extract and Inject
- assert composite propagator extracts remote SpanContext and baggage into context
- assert extracted context holds non-recording span until explicitly started with Tracer
- assert child span started from remote context inherits TraceID with new local SpanID
- assert unencoded baggage whitespace returns error on construction but is silently dropped on carrier extraction
- assert duplicate baggage keys resolve via last-value-wins precedence during extraction and creation
