Repo has to be outside usecases

[lexizz]

I've not understood why you put the Repo inside usecases layer. As I as know Repo relates of infrastructure layer, and there may be storage like postgresql, kafka, file and some external service.
And some business logic has to be inside usecases layer.
I mean this:

Storage

internal/storage
├── postgres
│   ├── translation
│   │   ├── entity.go      // struct entity's db, for scan (getting data into this struct entity)
│   │   └── translation.go // there are some requests to db
│   ├── system
│   │   ├── entity.go      // struct entity's db, for scan (getting data into this struct entity)
│   │   └── system.go      // some requests to db
│   └── user
│       ├── entity.go      // struct entity's db, for scan (getting data into this struct entity)
│       └── user.go        // some requests to db
├── kafka
│   ├── translation
│   │   ├── entity.go      // struct entity's kafka consumer
│   │   └── translation.go // there are some requests to db
│   ├── system
│   │   ├── entity.go      // struct entity's kafka consumer
│   │   └── system.go      // some requests to db
│   └── user
│       ├── entity.go      // struct entity's kafka consumer
│       └── user.go        // some requests to db
├── google
│   ├── translation
│   │   ├── entity.go      // struct entity's google
│   │   └── translation.go // there are some requests to db
│   ├── system
│   │   ├── entity.go      // struct entity's google
│   │   └── system.go      // some requests to db
│   └── user
│       ├── entity.go      // struct entity's google
│       └── user.go        // some requests to db
└── storage.go             // description of interfaces entity's methods (translation, system, user) for implementation by other storage

UseCases (Services)

internal/usecases
├── translation
│   └── create.go
│   └── translate.go
│   └── convert.go
├── system
│   └── create.go
│   └── check.go
│   └── off.go
└── user
    └── create.go
    └── check_role.go
    └── notificate.go

Models

As you did mentioned, domain models are need to work between layers

Conclusion

All the layers are isolated and reused easy
