DpopPolicy
Access-token policy for OpenID4VCI issuance.
The SDK's issuance client always sends DPoP-bound tokens (RFC 9449, required by the HAIP profile). Some OID4VCI 1.0-compliant issuers only accept Bearer tokens and reject DPoP (typically with 401 access_token_missing).
Entries
Use DPoP when the issuer advertises it (dpop_signing_alg_values_supported in its /.well-known/oauth-authorization-server); otherwise downgrade to a Bearer token for that issuer only. ⚠️ While downgraded, a leaked access token is not sender-constrained: anyone who obtains it can redeem it. Switches back to DPoP automatically once the issuer advertises it.
HAIP-strict: never downgrade. Issuers without DPoP support fail with a clear ISSUANCE error.
