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 Unmarshal succeeds when decoding `name: main unknown: value` into `decodeTarget` without options
- assert the known `name` field decodes to `main` when unknown fields are present
- assert adding `yaml.DisallowUnknownFields` as the JSON option makes the same input fail
