## Appendix
### A. Authentication Flow Diagram
```
Registration Flow:
User → Frontend (Registration Form) → API (RegisterUserCommand)
→ Domain (User.Create) → Database → Response (User Created)
Login Flow:
User → Frontend (Login Form) → API (LoginCommand)
→ Verify Password → Generate JWT Token → Response (Token)
→ Frontend (Store Token) → API (Subsequent Requests with Bearer Token)
Protected API Request:
User → Frontend (With Token) → API (JWT Middleware validates token)
→ Authorized → Controller → Response
```
