## 🚀 Quick Start

**Pour comprendre rapidement ce qui a été fait:**
1. Lire [`AMELIORATIONS_ADMIN_RESUME.md`](./AMELIORATIONS_ADMIN_RESUME.md) (français, 5 min)
2. Consulter [`ADMIN_QUICK_SUMMARY.md`](./ADMIN_QUICK_SUMMARY.md) (anglais, détaillé)

**Pour démarrer immédiatement:**
```bash
# Backend: Les endpoints sont déjà actifs
GET /api/admin/health
GET /api/admin/health/history?hours=24
GET /api/admin/health/stats?hours=24
GET /api/admin/health/suggestions

# Frontend: Les composants sont déjà intégrés
# Ouvrir: http://localhost:9000/admin
# → Section "Intégrations critiques" affiche 10 services
# → Section "Health Intelligence" affiche historique + suggestions
```

## 🎯 Use Cases

### Cas d'Usage 1: "Je veux voir si tous mes services fonctionnent"

**Action:**
```bash
curl -H "Authorization: Bearer <token>" \
  https://api.myroadtrip.com/api/admin/health
```

**Résultat:**
```json
{
  "status": "healthy",
  "checks": {
    "database": true,
    "cache": true,
    "stripe": true,
    // ... 7 autres services
    "checkDuration": 1823
  }
}
```

**Lecture:**
- `status: "healthy"` → Tout fonctionne
- `status: "degraded"` → Services critiques OK, optionnels KO
- `status: "unhealthy"` → Services critiques KO

---

### Cas d'Usage 2: "Je veux voir l'historique des 24 dernières heures"

**Action:**
```bash
curl -H "Authorization: Bearer <token>" \
  "https://api.myroadtrip.com/api/admin/health/history?hours=24"
```

**Résultat:** Array de SystemHealthSnapshot (max 500 entrées)

**Utilisation:**
```typescript
const history = await adminService.getHealthHistory(24)
const uptime = history.filter(h => h.status === 'healthy').length / history.length * 100
console.log(`Uptime: ${uptime}%`)
```

---

### Cas d'Usage 3: "Je veux des statistiques d'uptime"

**Action:**
```bash
curl -H "Authorization: Bearer <token>" \
  "https://api.myroadtrip.com/api/admin/health/stats?hours=168"
```

**Résultat:**
```json
{
  "uptime": {
    "percentage": 99.8,
    "totalChecks": 288
  },
  "services": {
    "database": { "uptime": 100, "failures": 0 },
    "stripe": { "uptime": 98.5, "failures": 4 }
  },
  "averageCheckDuration": 1800,
  "incidents": [...]
}
```

---

### Cas d'Usage 4: "Je veux savoir quoi corriger en priorité"

**Action:**
```bash
curl -H "Authorization: Bearer <token>" \
  https://api.myroadtrip.com/api/admin/health/suggestions
```

**Résultat:**
```json
[
  {
    "service": "OpenAI",
    "issue": "AI features disabled",
    "suggestion": "Add valid OPENAI_API_KEY starting with 'sk-'...",
    "priority": "medium"
  }
]
```

**Frontend:** Composant `HealthSuggestions.vue` affiche automatiquement

])
    ↓
Determine status (healthy/degraded/unhealthy)
    ↓
Save to admin_health_history (Firestore)
    ↓
Return SystemHealthSnapshot
```

---

### Frontend Flow

```
AdminPage.vue
    ↓
Import HealthHistoryChart.vue + HealthSuggestions.vue
    ↓
Components call adminService methods
    ↓
adminService.getHealthStats(24)
