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 shareReplay with bufferSize one immediately replays the latest value to a concurrent subscriber without starting a second source subscription
- assert refCount keeps the source alive until the last subscriber unsubscribes and then tears it down
- assert dropping to zero subscribers before source completion clears the replay buffer so the next subscriber starts a fresh source without receiving the stale value
- assert after source completion the final value and completion remain cached for a late subscriber without another source subscription or teardown
