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
- CompactEncrypt and compactDecrypt perform direct symmetric encryption and decryption with A256GCM, returning the original plaintext and protected header
- decodeProtectedHeader parses JWE protected header without requiring decryption key
- CompactEncrypt and compactDecrypt support key wrapping with A256KW and content encryption with A256GCM
- EncryptJWT and jwtDecrypt encrypt JSON claims and validate standard claims including issuer, audience, and expiration
- compactDecrypt throws JWEDecryptionFailed with code ERR_JWE_DECRYPTION_FAILED when decrypted with incorrect key or tampered ciphertext
- compactDecrypt throws JWEInvalid with code ERR_JWE_INVALID when provided with malformed JWE compact string
- jwtDecrypt throws JWTExpired with code ERR_JWT_EXPIRED and claim exp when decrypting expired token
- jwtDecrypt throws JWTClaimValidationFailed with code ERR_JWT_CLAIM_VALIDATION_FAILED when issuer or audience claims mismatch expected values
