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 allowStaleOnFetchRejection: true returns stale data on fetchMethod rejection while default fetch rejects
- assert allowStaleOnFetchRejection: true resolves to undefined on cache miss when fetchMethod throws
- assert in-flight fetch coalescing causes single AbortSignal to reject all callers unless ignoreFetchAbort: true is configured
- assert allowStaleOnFetchAbort: true immediately resolves with stale data when AbortSignal triggers
- assert cache.set on existing key triggers dispose with reason 'set' unless noDisposeOnSet: true is configured
- assert cache.set on existing key resets TTL start time unless noUpdateTTL: true is configured
- assert forceFetch rejects with Error when fetchMethod returns undefined while fetch resolves to undefined
