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
- assert zero-value struct with omitempty is marshaled and not omitted
- assert zero time.Time with omitempty is marshaled as RFC3339 zero timestamp and not omitted
- assert non-nil pointer to zero value with omitempty is marshaled and not omitted
- assert nil pointer with omitempty is omitted
- assert both nil and empty slices with omitempty are omitted
- assert without omitempty nil slice marshals to null and empty slice marshals to empty array
