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
- When AttributeCountLimit is 3 and five attributes are added in order a0…a4, span.Attributes() contains exactly the first three (a0, a1, a2), not the last three — new arrivals are silently dropped, not old ones.
- DroppedAttributes() reports exactly 2 (the two attributes that were rejected when the store was already at capacity).
- When EventCountLimit is 3 and five events are added in order e0…e4, span.Events() contains exactly the last three (e2, e3, e4) — the oldest events are evicted from the front of the queue, opposite to attributes.
- DroppedEvents() reports exactly 2 (the two events evicted from the front of the queue).
