/// gRPC client for the F∆I Platform hub. /// /// Provides a typed Dart wrapper around the hub's gRPC services /// (Hub, HubAdmin) defined in `fai/platform`'s `proto/fai/v1/` /// directory. Used by F∆I Studio and any Tier-3 Dart/Flutter /// app (DigiScout, J∆I, Scout, …) that wants to talk to a hub. /// /// Status (2026-05-05): scaffold only. Generated proto bindings /// land in `lib/src/generated/` once the codegen step is wired /// in (`tools/generate.sh`). Until then, [HubClient] is a stub /// type that documents the intended surface. library; export 'src/hub_client.dart';
