Module protocol 

Modules

identity_token

The identity token is the only carrier of a session’s name. The hub mints signed tokens (iss HUB_ISSUER, EdDSA, verified by the relay against the hub’s JWKS); a client that cannot reach the hub mints the same shape unsigned (iss SELF_ISSUER, alg UNSIGNED_ALG, empty signature) and the relay treats the name as unverified. Keep the claim shape in sync with manabrew-hub/src/auth/token.rs.
