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 Resource.from_contents detects specification from $schema keyword and preserves schema contents
- assert Resource.from_contents raises CannotDetermineSpecification when $schema is absent unless default_specification is provided
- assert Registry is immutable and stores resources via with_resource and with_contents
- assert Resolver.lookup resolves schemas by absolute URI and JSON Pointer
- assert Resolver.lookup resolves internal resource schemas by $anchor
- assert Resolver with base_uri resolves relative references across registered resources
- assert Registry and Resolver raise NoSuchResource, Unresolvable, PointerToNowhere, and NoSuchAnchor on lookup errors
- assert Registry with custom retrieve callback dynamically resolves resources on demand
