## SignedRequestObjectRequirementValidator Class

Enforces the RFC 9101 §10\.5 `require_signed_request_object` client metadata: a client that
committed to it must deliver its authorization parameters as a signed request object\. A request
that came neither from a request object nor from a PAR\-stored request is plain parameters and is
rejected\. The PAR push itself runs through the same validator pipeline, so a flagged client
cannot smuggle plain parameters in via PAR either; the signature itself \(rejecting the
`none` algorithm\) is enforced by the request\-object fetcher where the JWT is validated\.

```csharp
public class SignedRequestObjectRequirementValidator : Abblix.Oidc.Server.Endpoints.Authorization.Validation.SyncAuthorizationContextValidatorBase
