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 RuntimeError is raised when an adapter returns a non-tuple shape instead of {request, response} or {request, exception}; Req.request/2 is used (not a stubbed plugin path).
- assert the RuntimeError message includes 'expected adapter to return {request, response} or {request, exception}'.
