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.
MIT-0

Contract
- assert StringDecoder decodes multi-byte UTF-8 sequences split across chunks preserving character boundaries
- assert StringDecoder end flushes incomplete trailing multi-byte sequences as unicode replacement characters
