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
- ParseTraceState enforces W3C syntax and fails when exceeding 32 members, while Insert prepends new entries, moves updated keys to the head, and silently drops tail entries exceeding the 32-member limit
- Delete removes targeted key while preserving remaining member order, and deleting nonexistent keys returns identical copy
- NewSpanContext requires non-zero TraceID and SpanID for validity, preserving TraceFlags, TraceState, and Remote status
- ContextWithRemoteSpanContext stores remote span context in context.Context and SpanFromContext returns a non-recording span preserving the remote context
