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
- EncryptJWT produces a 5-part compact encrypted JWT with direct encryption and A256GCM algorithm
- jwtDecrypt decrypts valid JWE tokens, returning the original claims and protected headers
- jwtDecrypt rejects tokens encrypted with an incorrect key, throwing JWEDecryptionFailed with code ERR_JWE_DECRYPTION_FAILED
- jwtDecrypt rejects expired tokens, throwing JWTExpired with code ERR_JWT_EXPIRED and claim exp
- jwtDecrypt validates issuer claim, rejecting mismatches with JWTClaimValidationFailed and reason check_failed
- jwtDecrypt validates audience claim, rejecting mismatches with JWTClaimValidationFailed and reason check_failed
- CompactEncrypt and compactDecrypt encrypt and decrypt raw Uint8Array byte payloads using symmetric key
