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
- Bun.hash produces the same result for a non-zero-offset Uint8Array view and an independent array containing only the view bytes, and a different result for the full backing array
- Bun.SHA256.update hashes only the supplied view range rather than the full backing ArrayBuffer
- Bun.gzipSync followed by Bun.gunzipSync preserves exactly the view bytes
- Bun.write persists exactly the view bytes and excludes the prefix and suffix in the backing array
