## 📋 Implementări Complete

### Backend

#### Autentificare JWT [C-01]
- ✅ `backend/auth.py` — JWT creation, validation, role checking
- ✅ `/users/login` — returnează `TokenResponse` (access_token, user_id, role, expirare 8h)
- ✅ Toți routers-ii — `Depends(get_current_user)` enforce
- ✅ Admin-only endpoints — `Depends(get_current_admin)`
- ✅ user_id — extras din JWT token, NU din request body [M-02]

#### Rate Limiting [H-02]
- ✅ `slowapi` integrat în requirements.txt
- ✅ `/items/extract-label` — `@limiter.limit("10/minute")` per IP
- ✅ Protecție împotriva spam pe AI endpoint

#### CORS Configurație [M-01]
- ✅ `ALLOWED_ORIGINS` din env var (fallback: localhost:3000, localhost:3002)
- ✅ Allow methods specific: GET, POST, PUT, DELETE, OPTIONS
- ✅ allow_credentials=True (valid cu specific origins)

#### Patch-uri Directe
- ✅ C-02 — Eliminat bypass password
- ✅ C-03 — Admin seed cu parola aleatoare
- ✅ H-01 — LDAP injection fix (escape_filter_chars)
- ✅ H-03 — MIME validation + 10MB limit upload
- ✅ M-03 — Logging LDAP via log.debug()

### Frontend

#### JWT Handling [L-01]
- ✅ `frontend/lib/auth.ts` — saveToken, getToken, getAuthHeader, clearAuth
- ✅ Token storage — localStorage (inventory_token + inventory_user)
- ✅ Login page — salveaza TokenResponse din /users/login
- ✅ Token attach — Axios interceptor adauga `Authorization: Bearer <token>` pe toate cererile

#### Token Expiry [L-01]
- ✅ 401 Unauthorized → clearAuth() + redirect /login
- ✅ Interceptor pe axiosInstance
- ✅ Auto-logout pe expirare

### Deployment

#### docker-compose.yml
- ✅ Backend environment vars: DATA_DIR, LOGS_DIR, ALLOWED_ORIGINS, JWT_SECRET_KEY
- ✅ Comentarii pentru producție
- ✅ Fallback values pentru development

#### Environment Variables

| Var | Dev Default | Prod Requă | Purpose |
|-----|-------------|-----------|---------|
| ALLOWED_ORIGINS | localhost:3000, localhost:3002 | SETEAZĂ! | CORS origins |
| JWT_SECRET_KEY | ephemeral (random) | SETEAZĂ! | JWT signing key |
| DATA_DIR | /app/data | - | Database location |
| LOGS_DIR | /app/logs | - | Logs location |

## 🚀 Producție — Checklist

**CRITICE — SETEAZĂ ÎNAINTE DE DEPLOY:**

- [ ] **JWT_SECRET_KEY** — Generează cu `openssl rand -hex 32`
- [ ] **ALLOWED_ORIGINS** — Setează originile reale (ex: https://inventory.example.com)
- [ ] **TLS/HTTPS** — Caddy proxy configurate cu certificat valid
- [ ] **Database backup** — SQLite data/ mappped la persistent volume
- [ ] **Logs rotation** — logs/ mappped și monitorizate

**RECOMANDATE:**

- [ ] Setează log level → WARNING (nu DEBUG)
- [ ] Configureaza rate limiting pe alt nivel (nginx/cloudflare) pentru DDoS
- [ ] Monitorizare alertă pe 401 spikes (token expiry issues)
- [ ] Rotire periodică JWT_SECRET_KEY

## 📝 Testing Local

### 1. Run Development Setup
```bash
docker-compose up --build
```

### 2. Test Login
```bash
curl -X POST http://localhost:8000/users/login \
  -H "Content-Type: application/json" \
  -d '{"username": "Admin", "password": "<initial_password_din_logs>"}'
```

### 3. Test Protected Endpoint cu Token
```bash
curl -H "Authorization: Bearer <access_token>" \
  http://localhost:8000/items/
```

### 4. Test 401 (token expired)
```bash
curl -H "Authorization: Bearer invalid" \
  http://localhost:8000/items/
# Expect: 401 Unauthorized
```

### 5. Test Rate Limiting (extract-label)
```bash
# 11 cereri rapid — 11-a trebuie să fail cu 429
for i in {1..15}; do
  curl -X POST -F "file=@image.jpg" \
    -H "Authorization: Bearer <token>" \
    http://localhost:8000/items/extract-label
  sleep 0.1
done
```

## ✅ Validări

- ✅ Backend complet securizat
- ✅ Frontend token handling complet
- ✅ Rate limiting pe AI endpoint
- ✅ CORS configurable
- ✅ Toți routers-ii au auth enforcement
- ✅ Token expiry + redirect login
- ✅ Admin role check funcțional
- ✅ LDAP injection protected
- ✅ File upload validation
- ✅ Audit logging cu user_id din token

## 🎓 Lecții Învățate

1. **CORS cu credentials=True** — trebuie origins specifice, NU wildcard
2. **Rate limiting** — esențial pe endpoints costisitoare (AI)
3. **JWT expirare** — 8h e balanță bună între security + UX
4. **user_id din token** — elimină spoof-uri pe operații
5. **Debug logging** — PII leaks (DN-uri LDAP) dacă nu e grijă
