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
- createFromFd creates read streams that slice specific byte ranges from a file descriptor
- createFromFd creates write streams that write bytes at specific offsets in a file descriptor
- createFromFd reads and writes chunks concurrently with serialized operations via read and write methods
- createFromFd with autoClose option closes the underlying file descriptor when all references are unrefed
- createFromBuffer creates read streams that slice sections from an in-memory buffer
- createFromBuffer creates write streams that write slices into an in-memory buffer
