## 2. METODOLOGÍA: 3 FASES OBLIGATORIAS

### 2.1 FASE 1: Análisis (Completada)

**Objetivo:** Identificar páginas viables basadas en disponibilidad de datos.

**Criterios de Viabilidad:**
1. La página debe consumir datos de tablas de BD
2. Esas tablas deben actualizarse cuando el estudiante usa la plataforma
3. Deben existir triggers o procesos automáticos que mantengan los datos actualizados

**Resultado del Análisis:**

```

### 3.2 Tablas de Base de Datos Utilizadas

| Tabla | Schema | Actualizada por Student | Trigger |
|-------|--------|------------------------|---------|
| `exercise_attempts` | progress_tracking | ✅ Directamente | - |
| `exercise_submissions` | progress_tracking | ✅ Directamente | - |
| `module_progress` | progress_tracking | ✅ Via trigger | `trg_update_module_progress` |
| `student_intervention_alerts` | progress_tracking | ✅ Via trigger | `trg_generate_alerts` |
| `user_stats` | gamification_system | ✅ Via trigger | `trg_update_user_stats` |
| `user_ranks` | gamification_system | ✅ Via trigger | `trg_check_rank_promotion` |
| `classrooms` | social_features | ❌ CRUD Teacher | - |
| `classroom_members` | social_features | ❌ Admin/Teacher | - |
| `profiles` | auth_management | ❌ Auth flow | - |
| `exercises` | educational_content | ❌ Admin CRUD | - |

### 3.3 RLS (Row Level Security)

El Teacher solo puede ver datos de estudiantes en sus classrooms:

```sql
-- Política RLS para exercise_attempts
CREATE POLICY teacher_view_classroom_attempts ON progress_tracking.exercise_attempts
    FOR SELECT TO authenticated
    USING (
        user_id IN (
            SELECT cm.user_id
            FROM social_features.classroom_members cm
            JOIN social_features.teacher_classrooms tc
                ON tc.classroom_id = cm.classroom_id
            WHERE tc.teacher_id = auth.uid()
        )
    );
```

    const classroomIds = await this.getTeacherClassrooms(teacherId);

    // 2. Construir query con filtros
    const qb = this.attemptRepo
      .createQueryBuilder('attempt')
      .innerJoin('attempt.user', 'user')
      .innerJoin('attempt.exercise', 'exercise')

      .where('cm.classroom_id IN (:...classroomIds)', { classroomIds });

    // 3. Aplicar filtros opcionales
    if (query.classroom_id) {

      .skip((query.page - 1) * query.limit)
      .take(query.limit)
