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
- chacha20poly1305.New creates an AEAD cipher with valid 32-byte key
- chacha20poly1305.New rejects invalid key length with an error
- aead.NonceSize returns standard 12-byte nonce size
- aead.Overhead returns 16-byte authentication tag overhead
- aead.Seal and aead.Open encrypt and decrypt plaintext with additional data
- aead.Open returns authentication failure error when ciphertext or tag is modified
- aead.Open returns authentication failure error when additional data does not match
