## DeviceAuthorizationDetailsValidator Class

Thin endpoint\-side adapter that delegates the RFC 9396 §3 device\-flow
`authorization_details` validation to
[ApplyAsync\(JsonArray, ClientInfo, CancellationToken\)](https://www.abblix.com/en/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Features.RichAuthorizationRequests.IAuthorizationDetailsPolicy#Abblix.Oidc.Server.Features.RichAuthorizationRequests.IAuthorizationDetailsPolicy.ApplyAsync(System.Text.Json.Nodes.JsonArray,Abblix.Oidc.Server.Features.ClientInformation.ClientInfo,System.Threading.CancellationToken) 'Abblix\.Oidc\.Server\.Features\.RichAuthorizationRequests\.IAuthorizationDetailsPolicy\.ApplyAsync\(System\.Text\.Json\.Nodes\.JsonArray, Abblix\.Oidc\.Server\.Features\.ClientInformation\.ClientInfo, System\.Threading\.CancellationToken\)') and propagates the
[OidcError](https://www.abblix.com/en/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Common.OidcError 'Abblix\.Oidc\.Server\.Common\.OidcError') as\-is\. All actual policy lives on the composite so /authorize,
/par, CIBA and device\-flow endpoints share one source of truth\.
