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
- duplexer2(writable, readable) returns a Duplex stream combining writable and readable streams
- writing data to duplex stream forwards chunks to the underlying writable stream
- reading data from duplex stream pulls chunks from the underlying readable stream
- duplexer2 bubbles error events from writable stream to duplex stream by default
- duplexer2 bubbles error events from readable stream to duplex stream by default
- duplexer2 suppresses error bubbling when bubbleErrors option is false
- duplexer2 supports stream options such as objectMode
