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
- yaml.Unmarshal decodes valid YAML scalar, list, and map structures into matching Go struct fields
- yaml.Marshal serializes Go structs into valid YAML with correct field names, types, and struct tags
- yaml.Unmarshal handles omitempty struct tags by excluding empty slices and maps during Marshal
- yaml.UnmarshalStrict returns a TypeError when encountering unknown fields or duplicate keys
- yaml.Unmarshal correctly decodes into custom Unmarshaler implementations
- yaml.Marshal correctly encodes types implementing the custom Marshaler interface
