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 the offline adapter first receives POST /start whose body iodata becomes the exact JSON bytes and whose content-type is application/json
- assert the adapter's 303 Location response triggers a second offline request to /final as GET with nil body and no content-type
- assert Req.request! returns the second adapter response with status 200 and body ok
