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 standard 12-byte NonceSize and 16-byte Overhead
- chacha20poly1305.New rejects invalid key lengths not matching 32 bytes
- chacha20poly1305.NewX creates an AEAD cipher with extended 24-byte NonceSize and 16-byte Overhead
- chacha20poly1305.NewX rejects invalid key lengths not matching 32 bytes
- aead.Seal and aead.Open correctly encrypt and decrypt plaintext with additional authenticated data
- aead.Open rejects tampered ciphertext or corrupted authentication tag
- aead.Open rejects mismatched additional authenticated data
- aeadX.Seal and aeadX.Open round-trip plaintext with 24-byte extended nonce
