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
- EncryptJWT produces a 5-part compact encrypted JWT with direct symmetric encryption (dir + A256GCM) that can be decrypted with jwtDecrypt
- EncryptJWT produces an encrypted JWT using symmetric key wrapping (A256KW + A256GCM)
- EncryptJWT produces an encrypted JWT using RSA public key encryption (RSA-OAEP-256 + A128CBC-HS256)
- EncryptJWT supports dynamic key resolution via key resolver callback during decryption
- EncryptJWT enforces exp and nbf claims throwing JWTExpired or JWTClaimValidationFailed when invalid
- EncryptJWT throws JWEInvalid when attempting to encrypt without protected or unprotected headers
- EncryptJWT encrypted token fails decryption with JWEDecryptionFailed when decrypted with incorrect key or tampered ciphertext
