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
- When retries on 5xx responses are exhausted, agent.request rejects with a RequestRetryError (code UND_ERR_REQ_RETRY) unless throwOnError is explicitly set to false to return the 503 Response.
- Retries transient 503 responses for idempotent GET requests and resolves the subsequent 200 response
- Non-idempotent POST requests that receive 503 are not retried by default and throw immediately on the first attempt
- Composing interceptors.retry before interceptors.redirect places redirect on the outer layer, retrying failed target endpoints directly without re-requesting the initial redirect origin
