+# Resumen de Cambios - Sesión de Desarrollo (Rama `dev`)
+
+**Fecha:** 2026-09-02 / 2026-09-03  
+**Proyecto:** Admin Edu-Space (Flask + PostgreSQL)  
+**Rama:** `dev`  
+
+---
+
+## 1. Auditoría Git y Puesta en Producción
+* **Informe Técnico Completo (`DEPLOYMENT_AUDIT.md`):**
+  * Análisis de ramas locales y remotas (`main`, `dev`, `origin/planning`, `origin/commissions`, `origin/spanish`).
+  * Manual de despliegue en producción con arquitectura WSGI (Gunicorn), Nginx como proxy inverso, Systemd unit y contenedorización Docker / Docker Compose.
+* **Archivos Base:**
+  * Creación de `.env.example` con todas las variables requeridas (PostgreSQL, Flask, Secret Key, Babel).
+  * Creación de `init_db.py` para bootstrap inicial seguro de base de datos y usuario administrador por defecto (`admin@edu-space.com` / `admin123`).
+
+---
+
+## 2. Base de Datos y Modelos
+* **Preferencia de Idioma Persistente:**
+  * Migración en PostgreSQL agregando la columna `preferred_language VARCHAR(10)` a la tabla `users`.
+  * Actualización del modelo `User` en `app/models/user.py` con el campo `preferred_language`.
+
+---
+
+## 3. Implementación de Vistas y Plantillas Faltantes
+* **Perfil de Usuario (`app/templates/auth/profile.html`):**
+  * Vista completa con datos del usuario, rol, estado, fecha de registro y reservas recientes.
+  * Formulario interactivo para configurar la **Preferencia de Idioma** (*Detectar automáticamente del navegador*, *Español*, *English*).
+* **Cambio de Contraseña (`app/templates/auth/change_password.html`):**
+  * Formulario seguro para actualización de credenciales.
+* **Manejo de Errores (`app/templates/auth/403.html`):**
+  * Pantalla de error 403 Forbidden estilizada.
+
+---
+
+## 4. Correcciones de UX y Bugs de Rutas
+* **Navbar Limpio (`app/templates/base.html`):**
+  * Eliminación del bloque duplicado del menú de usuario `System Administrator`.
+* **Corrección de BuildError en Comisiones:**
+  * En `app/routes/classrooms.py`, se agregó el alias de ruta `@classrooms_bp.route('/', endpoint='index')` para resolver enlaces a `classrooms.index`.
+  * En `app/templates/schedule/commissions.html`, se reemplazó el filtro inválido de Django `truncatewords(20)` por el filtro estándar de Jinja2 `truncate(100)`.
+* **Corrección Visual en `/genetic-optimizer` (`app/templates/genetic_optimizer.html`):**
+  * Se agregó el espaciado `pt-5 mt-4` evitando que la barra de navegación fija superior (`fixed-top`) se monte sobre el contenido.
+  * Rediseño de tarjeta hero con contraste óptimo y reemplazo de iconos faltantes por Bootstrap Icons (`bi bi-...`).
+* **Corrección en Calendario (`app/templates/schedule/calendar.html`):**
+  * Inclusión de contenedor con espaciado superior y bundle de localización `locales-all.min.js` para FullCalendar.
+
+---
+
+## 5. Internacionalización (i18n) y Localización al Español
+* **Configuración del Motor Babel (`config/config.py` y `babel.cfg`):**
+  * Configuración de `BABEL_TRANSLATION_DIRECTORIES` con ruta absoluta.
+  * Actualización del método de extracción Jinja2 en `babel.cfg`.
+* **Formularios con Traducción Lazy (`lazy_gettext`):**
+  * `app/forms/auth.py` (`LoginForm`).
+  * `app/forms/classroom.py` (`ClassroomForm`, `ClassroomResourceForm`).
+  * `app/forms/reservation.py` (`ReservationForm`).
+* **Traducción Integral de Plantillas:**
+  * `app/templates/auth/login.html`: Pantalla de login traducida y con selector de idioma visible.
+  * `app/templates/dashboard.html`: Todas las tarjetas estadísticas, acciones rápidas y tablas.
+  * `app/templates/classrooms/list.html` y `add.html`: Filtros, estados vacíos, cabeceras y formularios.
+  * `app/templates/schedule/today.html`: Horario del día, métricas y botones.
+  * `app/templates/schedule/calendar.html`: Vistas, leyendas y eventos.
+  * `app/templates/genetic_optimizer.html`: Estado del algoritmo y controles.
+  * `app/templates/partials/language_switcher.html`: Muestra "Español" en lugar de "Spanish".
+* **Compilación de Catálogos:**
+  * Compilación binaria de `messages.po` a `messages.mo` en `translations/es/` y `translations/en/` con 0 mensajes pendientes.
+
+---
+
+## 6. Lógica de Detección y Precedencia de Idiomas
+En `app/__init__.py` (`get_locale()`):
+1. **Parámetro URL (`?lang=`):** Máxima prioridad para cambio explícito.
+2. **Preferencia en Perfil del Usuario (`current_user.preferred_language`):** Sobrescribe la configuración del navegador en toda la sesión si el usuario está autenticado.
+3. **Preferencia de Sesión (`session['language']`):** Cambio manual mediante el dropdown.
+4. **Detección Automática del Navegador (`request.accept_languages.best_match()`):** Valor por defecto para visitantes no autenticados y pantalla de login.
+* Al cerrar sesión (`logout`), se limpia la sesión para que el login use el navegador.
+* Al cambiar el idioma en el selector siendo usuario autenticado, se sincroniza automáticamente con su perfil en base de datos.
+
+---
+
+## 7. Configuración del Entorno de Desarrollo
+* Se creó `.vscode/settings.json` apuntando al intérprete del entorno virtual (`venv\Scripts\python.exe`), solucionando falsos positivos del analizador estático para `flask_wtf` y `flask_babel`.

+# Auditoría Técnica y DevOps: Git, Arquitectura y Puesta en Producción
+
+**Repositorio:** `admin-edu-space`  
+**Rol:** Tech Lead / DevOps Lead  
+**Fecha de Auditoría:** 2 de Septiembre de 2026  
+**Entorno de Auditoría:** Windows / Git 2.x / Python 3.12.4  
+
+---
+
+## Resumen Ejecutivo
+
+El presente documento constituye la auditoría integral de código, gestión de versiones (Git), arquitectura de software y preparación para producción del proyecto **Edu-Space Admin Panel** (`admin-edu-space`). 
+
+### Conclusiones Principales:
+1. **Rama seleccionada para despliegue:** **`main`** (commit `3d4e999`). Es la única rama que integra la totalidad de los cambios, bugfixes y features desarrollados en las ramas remotas (`planning`, `commissions`, `spanish`). No existen ramas divergentes sin fusionar.
+2. **Nivel de Madurez CI/CD:** **Crítico (0% Automatización)**. No existen flujos de trabajo en GitHub Actions, GitLab CI ni validación de pruebas automatizadas previas al merge.
+3. **Seguridad & Configuración:** **Riesgo Alto**. El archivo `.env` se encuentra actualmente trackeado en el repositorio Git con credenciales por defecto. Se requiere eliminarlo del índice, generar `.env.example` y rotar credenciales.
+4. **Infraestructura de Despliegue:** El repositorio carece de `Dockerfile`, `docker-compose.yml`, scripts de systemd y no incluye un servidor WSGI de producción (`gunicorn`) en `requirements.txt`. El paso a producción requiere los artefactos y procedimientos estandarizados que se detallan en este informe.
+
+---
+
+# Fase 1: Análisis de Ramas (Git Audit)
+
+## 1.1 Inventario de Ramas y Commits
+
+Se ejecutó la inspección exhaustiva de referencias locales y remotas:
+
+```bash
+git fetch --all
+git branch -a --sort=-committerdate
+git for-each-ref --format='%(refname:short) | %(committerdate:iso) | %(subject) | %(authorname)' refs/heads refs/remotes
+```
+
+### Tabla Comparativa de Ramas:
+
+| Rama | Tipo | Último Commit | Fecha del Commit | Autor | Estado respecto a `main` |
+| :--- | :--- | :--- | :--- | :--- | :--- |
+| **`main`** | Local / Remota | `3d4e999` | 2026-04-17 18:18:00 -0300 | `ale-vz` | **Rama Primaria (HEAD)** |
+| **`origin/planning`** | Remota | `ec977bf` | 2026-04-17 18:14:59 -0300 | `Alejandro Vazquez` | **100% Fusionada** (Merge PR #2 en `3d4e999`) |
+| **`origin/commissions`**| Remota | `18f1d3a` | 2026-03-30 17:37:53 -0300 | `Alejandro Vazquez` | **100% Fusionada** (Incluida en historia de `planning`) |
+| **`origin/spanish`** | Remota | `9af25df` | 2026-03-30 17:11:13 -0300 | `Alejandro Vazquez` | **100% Fusionada** (Merge PR #1 en `d4281cd` y PR #2) |
+
+### Verificación de Divergencias:
+Al ejecutar `git branch -r --no-merged main`, el resultado es **vacío**.
+Al verificar conteo simétrico `git rev-list --left-right --count <rama>...main`:
+- `origin/planning...main`: `0 2` (0 commits pendientes, 2 commits por delante en `main` por los merges).
+- `origin/commissions...main`: `0 6` (0 commits pendientes, 6 commits por delante en `main`).
+- `origin/spanish...main`: `0 7` (0 commits pendientes, 7 commits por delante en `main`).
+
+### Tags y Releases:
+- `git tag -l`: **Vacío**. No existen versiones etiquetadas (e.g. `v1.0.0`, `v0.1.0`) ni releases formales en el historial.
+
+## 1.2 Auditoría de CI/CD y Calidad de Código
+- **Workflows automatizados:** Inexistentes. No hay directorio `.github/workflows/`, ni `.gitlab-ci.yml`, ni archivo de integración continua de ningún proveedor.
+- **Validación de Tests en Pull Requests:** Los merges de los Pull Requests `#1` y `#2` se realizaron sin puertas de enlace automatizadas (quality gates).
+- **Cobertura de pruebas en repo:** Existe únicamente `tests/test_genetic_algorithm.py` enfocado en el motor heurístico, pero no se ejecuta en ningún pipeline.
+
+## 1.3 Dictamen Conclusivo de Rama para Despliegue
+
+> ### 🏆 Rama Determinada: **`main`** (Commit `3d4e999`)
+> 
+> **Justificación Técnica:**
+> 1. **Consolidación completa:** `main` agrupa de forma lineal y validada todas las funcionalidades de las ramas temáticas:
+>    - Incorpora las traducciones y arreglos de internacionalización (`spanish`).
+>    - Incorpora la lógica y vistas de comisiones (`commissions`).
+>    - Incorpora el motor de optimización de aulas y correcciones de UI (`planning`).
+> 2. **Cero pérdida de código (No regressions):** No existe ningún commit en las ramas remotas que no esté ya contenido en `main`.
+> 3. **Estabilidad comprobada:** Resuelve errores críticos de SQLAlchemy con carga ansiosa (`joinedload`) documentados en la evolución del repositorio.

+# Fase 2: Informe Técnico del Proyecto
+
+## 2.1 Stack Tecnológico y Propósito del Sistema
+
+### Propósito
+**Edu-Space Admin Panel** es una interfaz web de administración para la gestión, reserva y optimización algorítmica de aulas universitarias/académicas. El sistema permite:
+- Gestionar edificios, aulas, capacidad física y recursos técnicos (proyectores, computadoras).
+- Visualizar horarios y agendas en tiempo real mediante calendarios interactivos.
+- Administrar materias y comisiones docentes.
+- Asignar aulas automáticamente utilizando un **Algoritmo Genético** que evalúa aforo, prioridades horarias y resuelve conflictos de superposición de reservas.

+
+## 2.2 Requisitos de Entorno y Variables de Configuración
+
+### ⚠️ Hallazgos Críticos de Seguridad
+1. **Archivo `.env` versionado:** Se encontró el archivo `.env` físico bajo control de versiones Git con contraseñas en texto plano (`password`).
+   - *Acción correctiva obligatoria:* Ejecutar `git rm --cached .env`, añadirlo a `.gitignore` y rotar todas las credenciales antes de salir a producción.
+2. **Traducciones no compiladas:** El archivo `.gitignore` excluye deliberadamente `*.mo`. Por ende, el paso de build debe compilar los `.po` mediante `pybabel compile -d translations`.
+
+### Especificación de Variables de Entorno (`.env.example`)

+## 2.3 Puesta en Producción (Deployment Determinado)
+
+### 2.3.1 Estrategia de Contenedores (Docker + Docker Compose)
+
+Para garantizar un despliegue repetible e inmutable, se especifica el contenedor de producción:
+
+#### `Dockerfile` (Multi-stage / Producción)
+```dockerfile
+# Stage 1: Build de dependencias y compilación de traducciones
+FROM python:3.11-slim AS builder
+
+WORKDIR /app
+
+RUN apt-get update && apt-get install -y --no-install-recommends \
+    build-essential \
+    libpq-dev \
+    && rm -rf /var/lib/apt/lists/*
+
+COPY requirements.txt .
+RUN pip install --no-cache-dir --user -r requirements.txt && \
+    pip install --no-cache-dir --user gunicorn==21.2.0
+
+COPY . .
+# Compilar catálogos de traducción i18n
+RUN python -m babel.messages.frontend compile -d translations
+
+# Stage 2: Runtime limpio y seguro
+FROM python:3.11-slim AS runner
+
+WORKDIR /app
+
+RUN apt-get update && apt-get install -y --no-install-recommends \

+CMD ["gunicorn", "--workers=4", "--threads=2", "--bind=0.0.0.0:5000", "--access-logfile=-", "--error-logfile=-", "app:create_app()"]
+```
+
+#### `docker-compose.yml` (Stack Completo con PostgreSQL y Nginx)
+```yaml

+
+# 6. Inicializar esquema de base de datos (si la base está vacía)
+python -c "from app import create_app, db; app = create_app(); app.app_context().push(); db.create_all()"
+```
+
+#### 2. Configuración de Servicio Systemd (`/etc/systemd/system/eduspace.service`):
+```ini
+[Unit]
+Description=Edu-Space Admin Gunicorn Daemon
+After=network.target postgresql.service
+
+[Service]
+User=www-data
+Group=www-data
+WorkingDirectory=/var/www/admin-edu-space
+Environment="PATH=/var/www/admin-edu-space/venv/bin"

+    }
+}
+```
+
+---
+
+## 2.4 Verificación, Monitoreo y Health Checks
+
+### 2.4.1 Endpoint de Verificación Recomendado (`/healthz`)
+Actualmente el proyecto solo cuenta con endpoints protegidos por autenticación (`@login_required`). Para orquestadores (Kubernetes, AWS ALB, Docker), se debe incorporar una ruta pública de verificación en `app/routes/main.py`:
+
+```python
+@main_bp.route('/healthz')
+def healthz():
+    """Health check endpoint para balanceadores de carga y monitoreo"""
+    try:
+        # Validar conectividad con PostgreSQL
+        db.session.execute(db.text('SELECT 1'))
+        return jsonify({
+            'status': 'HEALTHY',
+            'database': 'CONNECTED',
+            'timestamp': datetime.utcnow().isoformat()
+        }), 200
+    except Exception as e:
+        return jsonify({
+            'status': 'UNHEALTHY',
+            'database': str(e),
+            'timestamp': datetime.utcnow().isoformat()
+        }), 503
+```
+
+### 2.4.2 Pruebas de Humo (Smoke Tests) Post-Despliegue
+
+Ejecutar la siguiente suite de verificación inmediata tras desplegar:
+
+```bash
+# 1. Comprobación de servicio y respuesta HTTP
+curl -I -k https://admin.edu-space.com/login
+# Respuesta esperada: HTTP/1.1 200 OK
+
+# 2. Comprobación del Health Endpoint
+curl -s https://admin.edu-space.com/healthz | jq .
+# Respuesta esperada: {"status": "HEALTHY", "database": "CONNECTED"}
+
+# 3. Comprobación de entrega de estáticos
+curl -I https://admin.edu-space.com/static/css/style.css
+# Respuesta esperada: HTTP/1.1 200 OK (o 304 Not Modified)
+
+# 4. Comprobación de logs de Gunicorn
+sudo journalctl -u eduspace.service -n 50 --no-pager
+```
+
+### 2.4.3 Matriz de Monitoreo y Observabilidad
+
+| Dimensión | Métrica Clave | Umbral de Alerta | Acción Correctiva |
+| :--- | :--- | :--- | :--- |
+| **Disponibilidad** | Tasa de Respuestas HTTP 5xx | `> 1%` en 5 min | Inspeccionar `error.log` de Gunicorn; revisar pool de conexiones BD |
+| **Latencia** | Tiempo de respuesta P95 | `> 1.5s` en endpoints | Revisar índices en tablas `reservations` y `classrooms` |
+| **Base de Datos** | Pool de conexiones agotado | Conexiones activas `> 85%` | Aumentar `max_overflow` en SQLAlchemy o activar PgBouncer |
+| **Optimización** | Tiempo de ejecución de Algoritmo Genético | `> 10s` en `/api/genetic/optimize` | Limitar rango de comisiones enviadas o desacoplar a Celery/Redis |
+
+---
+
+## 2.5 Roadmap de Mejoras DevOps & Calidad (Tech Lead Recommendations)
+
+1. **Implementar CI/CD con GitHub Actions:**
+   - Crear `.github/workflows/ci.yml` para ejecutar linting (`flake8` / `ruff`) y la suite de pruebas `unittest` en cada PR.
+2. **Desacoplar `.env` de Git:**
+   - Remover `.env` del repositorio (`git rm --cached .env`) e incorporar `python-dotenv` seguro mediante inyección de secretos en el pipeline.
+3. **Gestión Formal de Migraciones:**
+   - Ejecutar `flask db init` y generar el primer script de migración versionado en `migrations/versions/`.
+4. **Asincronía para el Algoritmo Genético:**
+   - Actualmente, la optimización heurística se ejecuta de forma sincrónica en el worker HTTP. Si el volumen de comisiones crece, puede bloquear el worker de Gunicorn (timeout 30s). Se recomienda migrar la ejecución pesada a una cola asíncrona con **Celery** o **Redis Queue (RQ)**.
+5. **Alinear Rutas Duplicadas:**
+   - Resolver la colisión de ruta entre `main_bp.route('/genetic-optimizer')` y `genetic_web_bp.route('/genetic-optimizer')`.

+- **`Gene`**: Single reservation assignment (classroom + commission + time)
+- **`Individual`**: Complete reservation schedule (chromosome)
+- **`GeneticAlgorithm`**: Main algorithm implementation
+- **`ReservationOptimizer`**: High-level interface layer
+
+#### Algorithm Configuration:
+- **Population Size**: 50 individuals
+- **Generations**: 100 evolution cycles
+- **Mutation Rate**: 10%
+- **Crossover Rate**: 80%
+
+### 2. API Endpoints (`app/routes/genetic_algorithm.py`)
+
+- **`POST /api/genetic/optimize`**: Run optimization
+- **`POST /api/genetic/preview-optimization`**: Preview results without applying
+- **`POST /api/genetic/apply-optimization`**: Apply optimized reservations
+- **`GET /api/genetic/commissions`**: Get available commissions
+- **`GET /api/genetic/algorithm-status`**: Get system status
+
+### 3. Frontend Interface
+
+#### Access Point:
+- **URL**: `/genetic-optimizer`
+- **Permissions**: Admin and Teacher roles only
+
+#### Features:
+- Commission selection interface
+- Real-time preview of optimization results
+- Fitness score visualization

+
+## Fitness Function Components
+
+The algorithm optimizes for multiple objectives:
+
+### 1. Capacity Efficiency (40% weight)
+- Perfect match: 1.0
+- <10% waste: 1.0
+- <30% waste: 0.8
+- <50% waste: 0.6
+- >50% waste: 0.4
+- Overfilled: 0.0
+
+### 2. Time Preference Satisfaction (30% weight)
+- Within 30 minutes: 1.0
+- Within flexibility window: 0.8 - 0.5
+- Beyond flexibility: max(0.0, 0.5 - penalty)
+
+### 3. Conflict Penalty (20% weight)
+- No conflicts: 1.0
+- Each conflict: -0.5 penalty
+
+### 4. Resource Matching (10% weight)
+- Based on classroom resources and subject requirements
+
+## Usage Examples
+
+### Basic Optimization
+
+```python
+from app.models.genetic_algorithm import ReservationOptimizer
+
+optimizer = ReservationOptimizer()
+
+# Optimize for specific commissions
+result = optimizer.optimize_schedule(
+    commission_ids=[1, 2, 3],
+    admin_user_id=1,
+    start_date=datetime(2024, 1, 15),
+    end_date=datetime(2024, 1, 20)
+)
+
+print(f"Fitness Score: {result['fitness_score']}")
+print(f"Reservations Created: {result['assigned_reservations']}")
+```
+
+### Applying Optimized Reservations
+
+```python
+# Apply to database
+reservations = optimizer.apply_optimized_reservations(result['reservations'])
+print(f"Applied {len(reservations)} reservations")
+```
+
+### API Usage
+
+```bash
+# Preview optimization

+# SQLAlchemy Relationship Issues - Professional Fix Summary
+
+## 🚨 Errors Identified
+```
+'Reservation' object has no attribute 'classroom'
+'Reservation' object has no attribute 'commission'  
+Error loading reservations 'app.models.reservation.Reservation object' has no attribute 'classroom'
+Error loading today's schedule: 'Reservation' object has no attribute 'classroom'
+```
+
+## 🔍 Root Cause Analysis
+- **Root Issue**: Missing SQLAlchemy relationship definitions in Reservation model
+- **Secondary Issue**: Conflicting backref names between models  
+- **Impact**: All reservation queries failing when accessing related data
+- **Affected Features**: Dashboard, scheduling, reservation listing
+
+## 🔧 Professional Solution Applied
+
+### 1. **Added Missing Relationships to Reservation Model**
+**File**: `/app/models/reservation.py`
+```python
+# BEFORE - Missing relationship definitions
+class Reservation(db.Model):
+    # Only foreign keys defined, no relationships
+
+# AFTER - Complete relationship definitions  
+class Reservation(db.Model):
+    # ... existing fields ...
+    
+    # Relationships
+    classroom = db.relationship('Classroom', backref=db.backref('reservation_list', lazy=True, cascade='all, delete-orphan'))
+    commission = db.relationship('Commission', backref=db.backref('reservation_list', lazy=True, cascade='all, delete-orphan'))
+    # User relationship already defined in User model
+```
+
+### 2. **Resolved Backref Conflicts**
+**Problem**: Both Reservation and User models trying to create 'reservations' backref
+**Solution**: 
+- Keep existing User model relationship: `reservations = db.relationship('Reservation', backref='user')`
+- Use unique backref names in Reservation: `reservation_list`
+
+### 3. **Removed Duplicate Commission Relationship**
+**File**: `/app/models/subject.py`
+```python
+# BEFORE
+class Commission(db.Model):
+    reservations = db.relationship('Reservation', backref='commission', lazy=True, cascade='all, delete-orphan')
+
+# AFTER  
+class Commission(db.Model):
+    pass  # Reservation already defines the relationship back to commission
+```

+# Schedule Route AttributeError - Professional Fix Summary
+
+## 🚨 Persistent Error
+```
+Error loading today's schedule: 'Reservation' object has no attribute 'classroom'
+```
+
+## 🔍 Root Cause Analysis
+- **Root Issue**: SQLAlchemy relationships not loaded when accessed in routes
+- **Location**: `/app/routes/schedule.py` - Multiple routes accessing relationships directly
+- **Problem**: Lazy loading not working with existing relationship configuration
+- **Impact**: Schedule, calendar, and API endpoints failing when accessing related data
+
+## 🔧 Professional Solution Applied
+
+### 1. **Added SQLAlchemy Eager Loading**
+**File**: `/app/routes/schedule.py`
+```python
+# BEFORE - Direct relationship access causing AttributeError
+reservations = Reservation.query.filter(
+    Reservation.start_time >= today_start,
+    Reservation.start_time <= today_end
+).order_by(Reservation.start_time).all()
+
+# Time blocks creation - This was failing
+time_blocks[hour_key].append({
+    'reservation': reservation,
+    'classroom': reservation.classroom,        # ❌ AttributeError here
+    'commission': reservation.commission,      # ❌ AttributeError here  
+    'user': reservation.user                   # ❌ AttributeError here
+})
+
+# AFTER - Using joinedload for eager loading
+from sqlalchemy.orm import joinedload
+
+reservations = Reservation.query.options(
+    joinedload(Reservation.classroom),
+    joinedload(Reservation.commission),
+    joinedload(Reservation.user)
+).filter(
+    Reservation.start_time >= today_start,
+    Reservation.start_time <= today_end
+).order_by(Reservation.start_time).all()
+
+# Now relationships are pre-loaded and accessible
+time_blocks[hour_key].append({
+    'reservation': reservation,
+    'classroom': reservation.classroom,        # ✅ Working
+    'commission': reservation.commission,      # ✅ Working
+    'user': reservation.user                   # ✅ Working
+})
+```
+
+### 2. **Fixed All Route Endpoints**
+Applied joinedload to all reservation queries:
+
+#### **Today Schedule Route** (`/schedule/today`)
+```python
+reservations = Reservation.query.options(
+    joinedload(Reservation.classroom),
+    joinedload(Reservation.commission),
+    joinedload(Reservation.user)
+).filter(...).all()
+```
+
+#### **Calendar Data Route** (`/schedule/calendar-data`)
+```python
+reservations = Reservation.query.options(
+    joinedload(Reservation.classroom),
+    joinedload(Reservation.commission)
+).filter(...).all()
+```
+
+#### **Today Events API** (`/schedule/api/today-events`)
+```python
+reservations = Reservation.query.options(
+    joinedload(Reservation.classroom),
+    joinedload(Reservation.commission)
+).filter(...).all()
+```
+
+### 3. **Fixed Syntax Errors**
+Corrected indentation issues in API routes that were causing SyntaxError during module import.
+
+## ✅ Professional Verification Results
+
+| Test Component | Status | Details |
+|----------------|--------|---------|
+| **Today Schedule Query** | ✅ PASS | 2 reservations found with all relations loaded |
+| **Classroom Relationship** | ✅ PASS | `reservation.classroom.name` returns "Principal-101" |
+| **Commission Relationship** | ✅ PASS | `reservation.commission.get_full_code()` returns "CS101-A-FALL2024" |
+| **Subject Access** | ✅ PASS | `reservation.commission.subject.name` returns "Introduction to Computer Science" |
+| **User Access** | ✅ PASS | `reservation.user.name` returns "System Administrator" |
+| **Time Blocks Creation** | ✅ PASS | No AttributeError when building time blocks |
+| **Calendar Data Generation** | ✅ PASS | Event titles created successfully |
+| **API Response** | ✅ PASS | JSON endpoints return complete data |
+
+## 📊 Real Data Test Results
+
+Using your actual database data:
+```sql
+-- Reservation ID 2 successfully processed
+-- Classroom: Principal-101 (Building: Principal) ✓
+-- Commission: CS101-A-FALL2024 ✓
+-- Subject: Introduction to Computer Science ✓
+-- User: System Administrator ✓
