%% ================== Relationships (Data/Control flow) ==================
%% Client <-> Server
ChromeExtension <--> WebApplicationServer : HTTP/JSON\n데이터 요청/반환

%% Auth
WebApplicationServer --> OAuthServer : 인증 요청
OAuthServer --> WebApplicationServer : 인증 정보 반환\n(토큰/프로필)

%% DB I/O
WebApplicationServer --> Database : 데이터 저장/조회
Database ..> WebApplicationServer : 데이터 반환

%% MQ & Worker
WebApplicationServer --> MessageQueue : 메일 수정/생성 위한 정보 전달
MessageQueue --> AIAPIWorker : 적재 데이터 전달(consume)
AIAPIWorker --> Database : 생성한 데이터 저장
AIAPIWorker ..> WebApplicationServer : (선택) 상태콜백/웹훅

%% Database composition
Database o-- User
Database o-- Recipient_lists
Database o-- Inputs
Database o-- Results

%% Domain relations
User "1" --> "many" Recipient_lists : user_id(FK)
Recipient_lists "1" --> "many" Inputs : recipient_id(FK)
Inputs "1" --> "0..1" Results : input_id(FK)

%% Server uses domain models
WebApplicationServer ..> User : uses
WebApplicationServer ..> Recipient_lists : uses
WebApplicationServer ..> Inputs : uses
WebApplicationServer ..> Results : uses
