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
- assert SHA-256 computation produces correct hexadecimal digest for empty and non-empty inputs
- assert SHA-512 computation produces correct 512-bit hexadecimal digest
- assert HMAC with SHA-256 generates valid message authentication code
- assert Keccak-256 computes expected hash digest
- assert HKDF key derivation with SHA-256 produces expected derived key of specified length
- assert PBKDF2 password-based key derivation produces deterministic derived key with configured iterations
