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
- derive Serialize and Deserialize on a struct
- assert a struct round-trips through JSON unchanged
- assert a missing optional field defaults instead of failing
- assert a type mismatch produces an error rather than a panic
