sdjwt.mjs: an issuer-signed JWT with the digests of the disclosable claims (_sd, list elements as {"...": digest}, _sd_alg sha-256),
the holder's key in cnf.jwk and exp, followed by the disclosures; the holder keeps the ones it picks and adds a Key Binding JWT
(kb+jwt, aud, nonce, iat, sd_hash); the verifier follows RFC 9901 sections 7.1 and 7.3 with the issuer key it chose, and requires its
audience and nonce, exp, and an explicitly typed token. Algorithms: ES256, EdDSA (Ed25519, the key every AERE identity has) and
ML-DSA-65 (JWK type AKP, names from the IETF draft draft-ietf-cose-dilithium, not yet a published standard).
Checked against the standard's own vectors (fixturi-rfc9901.json, from RFC 9901 Section 5 and Appendix A.5): the ten example
disclosure digests, the example SD-JWT signed by someone else with the A.5 key, and the example presentation with key binding, which
gives exactly the processed payload printed in the RFC. Not checked against another SD-JWT library.
An adversarial review before publication found ten defects, all fixed with a test and a planted negative control each (among them:
the issuer signed SD-JWT structure coming in claim values; the holder revealed an element with the same value from any list; audience
and nonce were not required). Tests: SD-JWT 22/22, negative control 28/28; identity 44/44.
