# Application

CQRS (Command Query Responsibility Segregation) vrstva mezi prezentací a doménou. Balíček `bus/` (middleware chain a dispatch). Handlery jsou organizované po doménových kontextech: `<context>/command/` (write), `<context>/query/` (read), volitelně `<context>/event/` (side-effects po commitu) -- např. `auth/command/`, `user/command/`, `profile/query/`. Závisí pouze na `domain/`.
