### 1.1 Trigger Function - update_user_stats_on_exercise_complete()

#### Test 1.1.1: Actualización Correcta de Stats

**Descripción:** Verificar que el trigger actualiza correctamente user_stats al insertar un exercise_attempt

**Setup:**
```sql
-- Usuario de prueba con stats iniciales
INSERT INTO gamification_system.user_stats (user_id, total_xp, ml_coins, ml_coins_earned_total, exercises_completed)
VALUES ('test-user-uuid', 0, 100, 0, 0);
```

**Ejecución:**
```sql
INSERT INTO progress_tracking.exercise_attempts (
    user_id,
    exercise_id,
    score,
    is_correct,
    xp_earned,
    ml_coins_earned
) VALUES (
    'test-user-uuid',
    'test-exercise-uuid',
    100,
    true,
    200,
    50
);
```

**Verificación:**
```sql
SELECT total_xp, ml_coins, ml_coins_earned_total, exercises_completed
FROM gamification_system.user_stats
WHERE user_id = 'test-user-uuid';
```

**Resultado Esperado:**
```
total_xp: 200
ml_coins: 150 (100 + 50)
ml_coins_earned_total: 50
exercises_completed: 1
```
