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
- proto.Clone creates an isolated deep copy where mutating cloned repeated slices, maps, or nested messages does not affect the original message.
- proto.Clone(nil) returns untyped nil when given untyped nil, and returns a typed nil interface whose ProtoReflect().IsValid() is false when given a typed nil pointer.
- proto.Clone preserves explicit presence for proto3 optional fields set to default zero values while keeping unpopulated implicit fields unpopulated.
- proto.Clone produces semantically equal deep copies across static known types and dynamic message descriptors.
