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
- StringDecoder() instantiates with default utf8 encoding and supports custom encodings like latin1, base64, and hex
- StringDecoder.prototype.write() buffers incomplete multi-byte UTF-8 sequences across chunk boundaries
- StringDecoder.prototype.write() decodes multi-byte UTF-8 sequences including 4-byte emojis when completed
- StringDecoder.prototype.write() returns complete ASCII and UTF-8 strings immediately
- StringDecoder.prototype.end() flushes trailing incomplete bytes as Unicode replacement characters
- StringDecoder.prototype.end(buffer) decodes the final buffer chunk and flushes the decoder
- StringDecoder.prototype.write() and end() decode base64 across buffer boundaries
- StringDecoder.prototype.write() and end() decode hex across buffer boundaries
