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 synchronous fetchMethod resolves immediately instead of returning an unresolved hanging promise
- assert dispose and disposeAfter fire with reason evict for stale entries evicted during in-flight background fetches
- assert onInsert does not fire for internal BackgroundFetch promise objects and only fires once on resolution with reason add
- assert cache.set overwriting a pending background fetch disposes the superseded stale entry with reason set
