Describe the steps required to obtain the credential(s) offered by a Credential Offer.

Resolves the offer and returns which grant-based flow applies and its ordered steps.

Start an issuance session for a Credential Offer.

For the authorization code grant, the session is left waiting_for_user_authorization, since completing it requires a wallet-driven redirect not yet implemented. tx_code is the transaction code obtained from the user out-of-band, if the offer requires one.

Return the current state of a previously started issuance session.

Complete the Credential Request for a session that has an access token.

Generates a key proof of possession through the wallet adapter — this server never signs anything itself — and hands the issued credential to the wallet for safekeeping. Its contents are never returned to the agent.
