+# Resumen de Cambios - Sesión de Desarrollo (Rama `dev`)
+
+**Fecha:** 2026-09-02 / 2026-09-03 / 2026-09-04  
+**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 y posterior actualización de `init_db.py` para bootstrap inicial seguro de base de datos, roles RBAC 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`.
+* **Preferencia de Tema Visual Persistente:**
+  * Migración agregando la columna `theme_preference VARCHAR(10) DEFAULT 'auto' NOT NULL` a la tabla `users`.
+  * Soporte en el modelo `User` para valores `'auto'`, `'light'` y `'dark'`.
+* **Control de Acceso Basado en Roles (RBAC):**
+  * Migración creando las tablas `roles` y `permissions`, y agregando la clave foránea `role_id` a la tabla `users`.
+  * Modelos `Role` y `Permission` en `app/models/role.py`.
+  * Métodos `has_permission(module, min_level)` y `can_manage()` en `User`.
+
+---
+
+## 3. Implementación de Vistas y Plantillas
+* **Perfil de Usuario (`app/templates/auth/profile.html`):**
+  * Vista completa con datos del usuario, rol, estado, fecha de registro y reservas recientes.
+  * Formulario integral para configurar **Idioma de la interfaz** (*Detectar automáticamente del navegador*, *Español*, *English*) y **Tema visual** (*Automático*, *Modo Claro*, *Modo Oscuro*).

+  * Formulario seguro para actualización de credenciales.
+* **Manejo de Errores (`app/templates/auth/403.html`):**
+  * Pantalla de error 403 Forbidden estilizada e integrada con el sistema de diseño.
+
+---
+
+## 4. Correcciones de UX, Linter 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 fija superior se monte sobre el contenido.
+  * Rediseño de tarjeta hero con contraste óptimo y reemplazo de iconos faltantes por Bootstrap Icons (`bi bi-...`).
+* **Corrección de Errores del Linter en `schedule/add.html` y `schedule/view.html`:**
+  * En `add.html`: Desacople de iteraciones Jinja a `<script type="application/json" id="classroom-data">` y parseo con `JSON.parse()`, eliminando 19 errores sintácticos del editor.
+  * En `view.html`: Formateo de la propiedad inline `style` en barras de progreso para cumplir con el validador CSS.
+
+---
+
+## 5. Rediseño UI/UX, Assets Institucionales y Modo Claro/Oscuro
+* **Exploración e Integración de Assets Gráficos:**
+  * Sincronización desde `app/resources` hacia `app/static/img/`:

+  * Tokens CSS para `:root` (Modo Claro) y `[data-bs-theme="dark"]` (Modo Oscuro).
+  * Clases especializadas: `.auth-card`, `.navbar-app`, `.user-avatar-small`, `.theme-toggle-btn`, `.badge-brand`.
+* **Modo Claro / Modo Oscuro Dinámico (`app/static/js/theme-toggle.js`):**
+  * Script anti-flickering en `<head>` para evitar parpadeos visuales al cargar la página.
+  * Botón toggle interactivo con persistencia en `localStorage`.
+  * En Modo Claro: Isotipo del navbar con filtro blanco puro (`brightness(0) invert(1)`) sobre el fondo magenta.
+  * Selector de idioma (`#languageDropdown`) con fondo y bordes de alto contraste y tilde de verificación blanca (`bi-check-lg`) visible **únicamente** en el idioma activo sobre gradiente magenta.
+
+---
+
+## 6. Internacionalización (i18n), Localización y Formateo de Fechas
+* **Detección Inteligente de Subtags Regionales (`get_locale` en `app/__init__.py`):**
+  * Extracción del subtag primario (`es` a partir de `es-419`, `es-AR`, `es-ES`), resolviendo el fallo donde Werkzeug saltaba erróneamente a inglés.
+  * Configuración institucional: `BABEL_DEFAULT_LOCALE = 'es'` y `LANGUAGES = ['es', 'en']`.
+* **Reglas de Idioma para la Pantalla de Login:**
+  * Resuelve según el navegador del visitante o recurre a español por defecto.

+  * Caja dinámica de resumen (JavaScript e `i18n-strings`) con cálculo de duración y validación de sobrecupo en español.
+
+---
+
+## 7. Módulo de Gestión de Accesos (RBAC) con Matriz FortiGate
+* **Modelos y Persistencia:**
+  * Módulo `app/models/role.py` con `Role` y `Permission`.
+  * Roles iniciales sembrados: `Admin` (total, protegido), `Docente` (reservas y horarios), `Operador` (aulas y reservas), `Consulta` (solo lectura).
+  * Vinculación del usuario inicial `admin@edu-space.com` al rol `Admin`.
+* **Matriz de Permisos Estilo FortiGate (`/admin/roles/edit/<id>`):**
+  * Tabla interactiva con columnas **Access Control** y **Permissions**.
+  * Segmented control por módulo con tres estados: `🚫 None`, `👁️ Read` y `✏️ Read/Write`.
+  * Color activo verde esmeralda FortiGate (`#2D9F6F`) con texto e icono en blanco puro.
+  * Menú desplegable masivo **Set All ▾** (*Set All to None*, *Set All to Read*, *Set All to Read/Write*).
+* **Módulo de Administración (`app/routes/admin.py`):**
+  * `/admin/roles`: Listado de roles, conteo de miembros, visualización de permisos en badges (RW, R, -) y modal de borrado seguro.
+  * `/admin/users`: Listado de cuentas con filtros por nombre, rol y estado (Activo/Inactivo), paginación y switch rápido para alternar accesos.
+  * `/admin/users/add` y `/admin/users/edit/<id>`: Formularios de alta y edición con asignación de rol y contraseña opcional.
+* **Seguridad y Decoradores (`app/utils/decorators.py`):**
+  * `@permission_required(module, min_level)` y `@admin_required`.
+  * Pestaña **Management** en el navbar visible exclusivamente para administradores.
+  * Botones de acción sensibles en el navbar (*Add Classroom*, *New Reservation*) condicionados a permisos de escritura.
+
+---
+
+## 8. Sincronización y Actualización de `init_db.py`
+* Migraciones DDL automáticas (`ALTER TABLE ... ADD COLUMN IF NOT EXISTS`) para `preferred_language`, `theme_preference`, `role_id`, y para la tabla `careers` y columna `career_id` en `subjects`.
+* Creación y siembra de roles institucionales y permisos en PostgreSQL.
+* Configuración de salida con codificación UTF-8 segura en Windows para evitar excepciones de `cp1252`.
+
+---
+
+## 9. Sincronización e Importación de Datos Académicos (Google Sheets)
+* **Modelo `Career` (`app/models/career.py`):**
+  * Entidad de carreras universitarias vinculada con `Subject` vía relación uno a muchos.
+  * Migración en PostgreSQL de la tabla `careers` y campo `career_id` en `subjects`.
+* **Servicio de Extracción ([app/services/sheets_importer.py](file:///c:/Workspace/admin-edu-space/app/services/sheets_importer.py)):**
+  * Integración con la cartelera oficial UniCABA 2026 a través de 6 hojas CSV (`Lunes` a `Sábado`).
+  * Normalización inteligente de espacios áulicos físicos (`Aula 402`, `Aula 302`), espacios virtuales (`VIRTUAL`), auditorios y salas de reunión.
+  * Extracción y parseo de franjas horarias (`8:00 a 9:00hs`, `17:30 a 21:30hs`).
+  * Rutina de **upsert** transaccional e idempotente que previene la duplicación de datos.
+  * Generación de reservas/clases en el calendario para poblar instantáneamente las vistas de horario diario y semanal.
+* **Interfaz de Gestión (`/admin/import`):**
+  * Vista interactiva con métricas en tiempo real (total de carreras, asignaturas, aulas, comisiones y clases).
+  * Botón de ejecución manual de sincronización con indicador visual de progreso (`spinner`).
+  * Reporte detallado de resultados y tabla con vista previa de asignaturas y comisiones sincronizadas.
+* **Acceso Rápido en Navbar (`app/templates/base.html`):**
+  * Nueva opción **"Import from Google Sheets"** incorporada en el menú desplegable **Management**, restringida a roles con permisos administrativos.
+
+---
+
+## 10. Correcciones en la Vista de Calendario (FullCalendar) y Códigos de Asignatura
+* **Carga de Eventos y Corrección de Error 500 (`/schedule/calendar-data`):**
+  * Se identificó y corrigió el error `AttributeError: 'str' object has no attribute 'value'` provocado por llamadas a `.status.value` sobre campos de estado textuales.
+  * Se implementó el TypeDecorator `StatusType` con la clase `StatusString` en `app/models/reservation.py` garantizando compatibilidad total tanto para `.status` como para `.status.value`.
+  * Sanitización de fechas ISO 8601 con zona horaria (`Z`, `-03:00`) enviadas por FullCalendar para comparación adecuada con campos `TIMESTAMP WITHOUT TIME ZONE` en PostgreSQL.
+  * Anclaje de fecha inicial con `initialDate: '{{ today_date }}'` para posicionar el calendario en la semana activa de cursada 2026.
+* **Corrección del Código de Asignatura (`subject_code`):**
+  * Se reemplazó la concatenación de código extendido de comisión (`Commission.get_full_code()` que arrojaba cadenas distorsionadas como `INGA0003-C1-2026-22026`) por el **código de asignatura real** del Sheet (`Subject.code`, ej. `INGA0003`, `ASIG00165`).
+  * Propiedades de acceso directo añadidas en `Reservation`: `subject_code`, `subject_name` y `classroom_name`.
+* **Jerarquía Visual y Renderizado de Tarjetas (`calendar.html`):**
+  * Implementación del hook `eventContent` en FullCalendar 5 para construir tarjetas personalizadas.
+  * **Nombre de la Asignatura** destacado como elemento principal con tipografía grande y en negrita (`font-weight: 700; font-size: 0.88rem`).
+  * **Código de Asignatura** y **Aula** mostrados como datos secundarios en badges de alto contraste (código con fondo oscuro translúcido y aula con isotipo y fondo blanco translúcido).
+  * Modal interactivo instantáneo al hacer clic en cualquier evento con todos los detalles académicos de la clase y enlace a la ficha completa.
+
+---
+
+## 11. Filtros por Aula y Materia en el Calendario de Reservas
+* **Barra de Herramientas de Filtros Interactiva (`calendar.html`):**
+  * **Filtrar por Aula:** Desplegable dinámico con todas las aulas activas ordenadas por edificio y código (físicas y virtuales). Al seleccionar un aula (ej. `Aula 402`), se eliminan todas las superposiciones visuales mostrando el cronograma limpio de ese espacio.
+  * **Filtrar por Materia:** Desplegable ordenado alfabéticamente con formato `[Código] Nombre de la Asignatura`. Permite aislar todas las clases de una asignatura en particular.
+  * **Filtrar por Carrera:** Filtro adicional por plan académico/carrera.
+  * **Botón Limpiar Filtros:** Restablece instantáneamente todos los controles y refresca la vista.
+  * **Insignias de Estado:** Indicador en tiempo real de los filtros aplicados y contador de clases visibles (`X clases visibles`).
+* **Soporte en Backend (`app/routes/schedule.py`):**
+  * `calendar_view`: Suministra las listas de `classrooms`, `subjects` y `careers` a la plantilla.
+  * `calendar_data`: Procesa `classroom_id`, `subject_id`, `career_id` y `search` aplicando cláusulas `filter()` con `JOIN` en SQLAlchemy.
+  * `refetchEvents()` de FullCalendar conectado a los eventos `change` de cada selector para recarga inmediata vía AJAX sin parpadeo de pantalla.
+
+---
+
+## 12. Módulo de Gestión de Edificios y Corrección de Vistas de Aulas
+* **Corrección de Plantillas de Aulas Faltantes:**
+  * Se crearon las plantillas [app/templates/classrooms/edit.html](file:///c:/Workspace/admin-edu-space/app/templates/classrooms/edit.html) y [app/templates/classrooms/view.html](file:///c:/Workspace/admin-edu-space/app/templates/classrooms/view.html), solucionando el error HTTP 500 (`TemplateNotFound: classrooms/edit.html`) y la redirección 302 que ocurría al hacer clic en cualquier aula.
+  * La vista de ficha técnica del aula ahora muestra detalles de capacidad, piso, estado, edificio y la tabla interactiva de próximas reservas.
+* **Modelo y Base de Datos de Edificios (`Building`):**
+  * Se creó el modelo [app/models/building.py](file:///c:/Workspace/admin-edu-space/app/models/building.py) (`id`, `name`, `code`, `address`, `floors`, `description`, `is_active`, timestamps y relación con `Classroom`).
+  * Migración DDL en PostgreSQL (`CREATE TABLE buildings`, `ALTER TABLE classrooms ADD COLUMN building_id`).
+  * Actualización de [init_db.py](file:///c:/Workspace/admin-edu-space/init_db.py) y siembra de edificios institucionales iniciales (`Edificio Central` y `Campus Virtual`) con vinculación de las 25 aulas existentes.
+* **Rutas y Gestión Completa (`app/routes/buildings.py`):**
+  * `/buildings`: Listado con métricas de infraestructura (total de edificios, aulas activas, capacidad total y plantas/pisos), barra de búsqueda y filtros por estado.
+  * `/buildings/<id>`: Vista de detalle con distribución de aulas organizadas visualmente por piso (Planta Baja, Piso 1, Piso 2, etc.), capacidad por sala y acciones directas.
+  * `/buildings/add` y `/buildings/<id>/edit`: Formularios con validación WTForms para alta y actualización.
+  * `/buildings/<id>/toggle` y `/buildings/<id>/delete`: Control de activación y eliminación protegida (impide borrar edificios que contengan aulas asignadas).
+* **Navegación (`app/templates/base.html`):**
+  * Enlace a **Edificios** (`/buildings`) incorporado en el menú **Classrooms** y en el menú administrativo **Management**.
+
+---
+
+## 13. Mapeo de Campos del Google Sheet y Concepto de Turno (Mañana / Tarde)
+* **Uso de los 5 Campos de la Cartelera Oficial:**
+  * **Codigo (`Subject.code` y `Commission.code`):** Almacena el código académico real (`INGA0003`, `ASIG00165`). Se expone como badge monoespaciado en eventos de calendario, comisiones y vistas administrativas.
+  * **Asignatura (`Subject.name`):** Título principal de la materia destacado en texto grande y en negrita en FullCalendar y en la cartelera diaria.
+  * **Aula (`Classroom.code`, `Classroom.building`, `Classroom.floor`, `Classroom.capacity`):** Normalización de espacios físicos y virtuales vinculados al nuevo modelo `Building`.
+  * **Carrera (`Career.name` y `Subject.career_id`):** Entidad de carrera universitaria con relaciones relacionales normalizadas.
+  * **Horarios (`Commission.schedule`, `Reservation.start_time`, `Reservation.end_time`):** Rango horario parseado hacia objetos `datetime` nativos para el motor de reservas y el calendario.
+* **Modelado y Captura de Turnos (`TURNO MAÑANA` y `TURNO VESPERTINO`):**
+  * Se agregó la columna `shift` en las tablas `commissions` y `reservations` de PostgreSQL y en sus respectivos modelos de SQLAlchemy.
+  * El parser de [app/services/sheets_importer.py](file:///c:/Workspace/admin-edu-space/app/services/sheets_importer.py) identifica las filas delimitadoras de bloque (`TURNO MAÑANA` vs `TURNO VESPERTINO / TARDE`) y corrobora la hora de inicio (< 13:00hs = Mañana, $\ge$ 14:00hs = Tarde).
+  * Se sincronizaron todas las comisiones y reservas de cursada: 15 comisiones y 48 reservas en `Turno Mañana`; 191 comisiones y 364 reservas en `Turno Tarde / Vespertino`.
+  * En el Calendario de Reservas (`/schedule/calendar`) se añadió el selector **Filtrar por Turno** (`Todos`, `Mañana`, `Tarde / Vespertino`), permitiendo a los usuarios aislar las franjas horarias y resolver la alta concentración de clases en el horario vespertino (17:30 a 21:30hs).
+
+---
+
+## 14. Accesos Directos en Panel, Ocultamiento de Virtuales, Filtro por Piso, Dirección Oficial y Traducción
+* **Tarjetas Estadísticas como Accesos Directos Interactivos ([app/templates/dashboard.html](file:///c:/Workspace/admin-edu-space/app/templates/dashboard.html)):**
+  * **Total de Aulas (25):** Redirige a `/classrooms/list` con feedback visual de hover y elevación.
+  * **Total de Materias (206):** Redirige a `/schedule/commissions`.
+  * **Reservas de Hoy (18):** Redirige a `/schedule/today`.
+  * **Esta Semana (103):** Redirige a `/schedule/calendar`.
+  * Se añadieron microinteracciones CSS en [app/static/css/style.css](file:///c:/Workspace/admin-edu-space/app/static/css/style.css) (`.dashboard-stat-card`).
+* **Ocultar Aulas Virtuales y Filtro por Piso:**
+  * **Calendario ([app/templates/schedule/calendar.html](file:///c:/Workspace/admin-edu-space/app/templates/schedule/calendar.html)):** Switch interactivo *Ocultar Aulas Virtuales* (indica capacidad ilimitada) y selector *Filtrar por Piso* (`Planta Baja`, `Piso 1`, `Piso 2`, `Piso 3`, `Piso 4`). El backend `/schedule/calendar-data` excluye las aulas virtuales o filtra por número de piso.
+  * **Cartelera del Día ([app/templates/schedule/today.html](file:///c:/Workspace/admin-edu-space/app/templates/schedule/today.html)):** Barra de filtros completa con soporte para ocultar virtuales, piso y turno.
+  * **Listado de Reservas ([app/templates/schedule/list.html](file:///c:/Workspace/admin-edu-space/app/templates/schedule/list.html)):** Endpoint `/schedule/list` totalmente operativo con paginación de 20 registros, preservación de query params y filtros de piso, turno, virtuales, estado y rango de fechas.
+* **Dirección Oficial de la Sede Central:**
+  * Se configuró la dirección oficial de la Universidad de la Ciudad de Buenos Aires (UniCABA): **`Tte. Gral. Juan Domingo Perón 802, CABA`** en la base de datos, en [init_db.py](file:///c:/Workspace/admin-edu-space/init_db.py) y en el importador [app/services/sheets_importer.py](file:///c:/Workspace/admin-edu-space/app/services/sheets_importer.py).
+* **Traducción Integral al Español y Catálogo Babel:**
+  * Se agregaron traducciones en [translations/es/LC_MESSAGES/messages.po](file:///c:/Workspace/admin-edu-space/translations/es/LC_MESSAGES/messages.po) y se recompiló el binario `.mo` con `pybabel`.
+  * Textos traducidos: `Buildings` $\rightarrow$ *Edificios*, `Management` $\rightarrow$ *Gestión*, `Timeline View` $\rightarrow$ *Vista Cronológica*, `Grid View` $\rightarrow$ *Vista en Tabla*, `Active Classrooms` $\rightarrow$ *Aulas Ocupadas*, `All Reservations` $\rightarrow$ *Todas las Reservas*, `AI Room Optimizer` $\rightarrow$ *Optimizador de Aulas*, etc.
+
+---
+
+## 15. Actualización Integral de Roles RBAC, Capacidad Infinita (∞) y Horarios de Próximas Clases
+* **Actualización de Roles, Grupos de Acceso y Matriz de Permisos ([app/models/role.py](file:///c:/Workspace/admin-edu-space/app/models/role.py), [init_db.py](file:///c:/Workspace/admin-edu-space/init_db.py)):**
+  * Se amplió `SYSTEM_MODULES` para cubrir los 8 módulos del sistema:
+    1. `classrooms`: **Aulas y Espacios** (físicas, virtuales y capacidades).
+    2. `buildings`: **Edificios y Sedes** (Sede Central, Campus Virtual, plantas).
+    3. `reservations`: **Reservas de Aulas** (aprobación, confirmación, cancelación).
+    4. `schedule`: **Cartelera y Cronograma** (calendario, cartelera del día, comisiones).
+    5. `academic`: **Gestión Académica** (carreras, asignaturas, códigos).
+    6. `import`: **Sincronización Sheets** (importador Google Sheets).
+    7. `optimizer`: **Optimizador IA** (algoritmo genético áulico).
+    8. `users`: **Usuarios y Accesos RBAC** (cuentas, roles y matriz).
+  * Se actualizaron los perfiles estándar (`Admin`, `Docente`, `Operador`, `Consulta`) en PostgreSQL y en `init_db.py`.
+  * Se tradujeron completamente las plantillas [app/templates/admin/roles/list.html](file:///c:/Workspace/admin-edu-space/app/templates/admin/roles/list.html) y [app/templates/admin/roles/edit.html](file:///c:/Workspace/admin-edu-space/app/templates/admin/roles/edit.html) al español.
+* **Soporte de Capacidad Infinita (∞) y Aclaración ([app/forms/classroom.py](file:///c:/Workspace/admin-edu-space/app/forms/classroom.py), [app/templates/classrooms/edit.html](file:///c:/Workspace/admin-edu-space/app/templates/classrooms/edit.html)):**
+  * Se actualizó `ClassroomForm.capacity` con validador personalizado que admite el símbolo **`∞`**, `inf`, `0` o cualquier capacidad numérica positiva.
+  * Se corrigió la validación de `floor` con `InputRequired` y `NumberRange(min=0)` para aceptar Planta Baja (Piso 0).
+  * En la interfaz de edición y alta de aulas se incluyó el botón de acción rápida **`Ilimitada (∞)`** que rellena automáticamente el campo con el símbolo `∞`.
+  * Se añadió una leyenda explicativa directa: *"Para aulas virtuales o eventos sin aforo restringido, ingrese ∞ o 0 (Capacidad ilimitada)"*.
+  * Se tradujo el botón de guardado a *"Guardar Cambios"* (reemplazando *"Save Changes"*).
+  * El aula virtual institucional (`Campus Virtual - VIRTUAL`) se actualizó a capacidad `0` (`∞`), renderizando el badge `∞ Ilimitada` en listados y fichas.
+* **Próximas Clases: Visualización Exclusiva del Horario ([app/templates/dashboard.html](file:///c:/Workspace/admin-edu-space/app/templates/dashboard.html), [app/templates/classrooms/view.html](file:///c:/Workspace/admin-edu-space/app/templates/classrooms/view.html)):**
+  * En la tabla de *Próximas Reservas* del panel y en la ficha del aula se cambió la columna a **"Horario"**, removiendo la fecha del calendario y destacando únicamente el rango horario de cursada (ej. `17:30 - 21:30 hs`).
+
+---
+
+## 16. Desacoplamiento de Hitos Académicos: Catálogo Dinámico de Tipificaciones y Matriz RBAC
+* **Modelos de Datos ([app/models/milestone.py](file:///c:/Workspace/admin-edu-space/app/models/milestone.py), [app/models/__init__.py](file:///c:/Workspace/admin-edu-space/app/models/__init__.py)):**
+  * `MilestoneType`: Catálogo dinámico y administrable con `id`, `name`, `code` (slug único), `color` (hexadecimal), `description`, `sort_order` e `is_active`.
+  * `AcademicMilestone`: Relacionado mediante clave foránea `milestone_type_id` a `MilestoneType` en lugar de strings estáticos.
+  * Sembrado de 12 categorías iniciales predeterminadas (`Parcial 1`, `Parcial 2`, `TP 1`, `TP 2`, `TP 3`, `Recu. P1`, `Recu. P2`, `Recu. TP 1`, `Recu. TP 2`, `Recu. TP 3`, `Final`, `Otro`).

+* **Vistas y ABM en Management ([app/routes/admin.py](file:///c:/Workspace/admin-edu-space/app/routes/admin.py), [app/templates/admin/milestone_types/list.html](file:///c:/Workspace/admin-edu-space/app/templates/admin/milestone_types/list.html)):**
+  * Se añadió el ítem de navegación **"Tipificaciones"** al menú desplegable *Management*.
+  * Tabla completa con badges de color, slugs, switches interactivos de activación/desactivación y modales para dar de alta y editar tipificaciones.
+* **API y Modal del Docente ([app/routes/main.py](file:///c:/Workspace/admin-edu-space/app/routes/main.py), [example/aulas-unicaba-mvp/...](file:///c:/Workspace/admin-edu-space/example/aulas-unicaba-mvp/src/app/components/evento-modal/evento-modal.component.html)):**
+  * Se expuso el endpoint `GET /api/milestone-types` para consumo desacoplado.
+  * Se actualizó el modal de eventos académicos (`evento-modal.component.html` y `.ts`) desacoplando las opciones estáticas y cargando dinámicamente el catálogo de tipificaciones activas con fallback automático para funcionamiento offline.

+
+## 17. Rediseño de Calendario Estilo Google Calendar y Corrección Visual en Eliminación de Roles
+* **Manejo de Eventos Simultáneos y Densidad Visual ([app/templates/schedule/calendar.html](file:///c:/Workspace/admin-edu-space/app/templates/schedule/calendar.html)):**
+  * Se configuró FullCalendar con `eventMaxStack: 3`, evitando que decenas de reservas concurrentes reduzcan las columnas a franjas milimétricas del 3%.
+  * Se habilitó `dayMaxEvents: 3`, `dayMaxEventRows: true` y `moreLinkClick: 'popover'` nativo de Google Calendar con enlaces "+X más".
+  * Se fijaron `slotMinTime: "07:00:00"`, `slotMaxTime: "23:00:00"`, `slotDuration: "00:30:00"`, `slotLabelInterval: "01:00:00"` y `nowIndicator: true` con la línea roja indicadora de hora actual.
+* **Diseño de Tarjetas de Evento Píldora (`.gc-event-pill` / `.gc-month-pill`):**
+  * Estilo Google Calendar con barra lateral de color (magenta UniCABA `#B43E8E`, ámbar `#F59E0B` para pendientes, índigo `#6366F1` para aulas virtuales).
+  * Encabezado compacto con hora de inicio y badge de aula (`bi bi-door-open` o `bi bi-camera-video` con fondo suave para `VIRTUAL`).
+  * Tipografía en `0.78rem` con elipsis para evitar desbordes y sombras sutiles.
+  * Compatibilidad completa con modo oscuro (`[data-bs-theme="dark"]`).
+* **Modal Flotante Interactivo al Clic (`#eventPreviewModal`):**
+  * Reemplazo de la navegación directa por un popover flotante estilizado como Google Calendar.
+  * Banner artístico superior con accesos rápidos: editar (✏️), eliminar/cancelar (🗑️) y cerrar (✕).
+  * Fila principal con indicador cuadrado de color, título completo, código de materia y badge de estado/turno.
+  * Lista con íconos: 🕒 horario y fecha completa, 📍 aula/piso/sede (o enlace directo al Campus Virtual), 👤 carrera/comisión/docente, 📝 hito o notas.
+  * Botones de acción inferior: "Ver Ficha Completa" y "Cerrar".
+* **Corrección de Modal de Eliminación de Roles ([app/templates/admin/roles/list.html](file:///c:/Workspace/admin-edu-space/app/templates/admin/roles/list.html)):**
+  * Se trasladó el modal de confirmación de eliminación `#deleteRoleModal` fuera de la celda `<td>` y de la tabla `<table>`, situándolo a nivel raíz de la plantilla.
+  * Se corrigió el error visual donde el cuadro emergente temblaba, saltaba o se desplazaba por el recálculo de padding/scrollbar de Bootstrap en la celda de la tabla.
+
+---
+
+## 18. ABM de Comisiones con Hitos y Aula Virtual, Eliminación de Usuarios y Renombrado de Roles (Bedelía y Alumno)
+* **Renombrado de Roles Institucionales ([init_db.py](file:///c:/Workspace/admin-edu-space/init_db.py), base de datos PostgreSQL):**
+  * `Operador` pasó a denominarse **`Bedelía`** con foco en la gestión operativa de aulas, sedes, reservas, comisiones, importación y cartelera.
+  * `Consulta` pasó a denominarse **`Alumno`** con acceso de solo lectura al cronograma general, asignaturas y aulas.
+  * Se ejecutó la actualización en caliente de los registros existentes en PostgreSQL y se actualizaron los sembrados en `init_db.py`.
+* **Corrección Visual de Tipificaciones de Hitos ([app/templates/admin/milestone_types/list.html](file:///c:/Workspace/admin-edu-space/app/templates/admin/milestone_types/list.html)):**
+  * Se ajustó el contenedor a `pt-5 mt-4` evitando que el encabezado quede solapado bajo la barra de navegación fija.
+  * Se limpió la duplicación del nombre en la tabla (se eliminó la repetición del texto dentro de la celda).
+  * Se agregó la paleta rápida de colores institucionales UniCABA al modal de edición.
+  * Se agregó el botón y modal global de confirmación de eliminación `#deleteMilestoneTypeModal` sin saltos visuales.
+* **Eliminación de Usuarios ([app/routes/admin.py](file:///c:/Workspace/admin-edu-space/app/routes/admin.py), [app/templates/admin/users/list.html](file:///c:/Workspace/admin-edu-space/app/templates/admin/users/list.html)):**
+  * Se implementó el endpoint `POST /admin/users/delete/<id>` protegido contra la eliminación del usuario en sesión activa y del administrador único.
+  * Desvinculación automática de comisiones como docente para prevenir violaciones de integridad referencial.
+  * Botón rojo de eliminación con ícono de papelera y modal global `#deleteUserModal` fuera de la tabla para evitar desplazamientos.
+* **ABM Integral de Comisiones con Aulas Virtuales e Hitos ([app/models/subject.py](file:///c:/Workspace/admin-edu-space/app/models/subject.py), [app/models/milestone.py](file:///c:/Workspace/admin-edu-space/app/models/milestone.py), [app/routes/schedule.py](file:///c:/Workspace/admin-edu-space/app/routes/schedule.py), [app/templates/schedule/commissions.html](file:///c:/Workspace/admin-edu-space/app/templates/schedule/commissions.html), [app/templates/base.html](file:///c:/Workspace/admin-edu-space/app/templates/base.html)):**
+  * **Columna y Enlace de Aula Virtual:** Se añadió el campo `virtual_link` (VARCHAR 500) a `commissions`. Permite registrar enlaces directos a Zoom, Microsoft Teams, Google Meet o Campus Virtual.
+  * **Hitos de Evaluación vinculados a Comisiones:** Se añadió `commission_id` a `academic_milestones`. Permite asociar parciales, TPs y recuperatorios directamente a la comisión de cursada.
+  * **Permisos para Profesores, Bedelía y Admin:** Los roles `Docente`, `Bedelía` y `Admin` pueden configurar el aula virtual y registrar hitos académicos en sus comisiones.
+  * **Navegación:** Acceso directo a *Comisiones y Cursadas* disponible en la barra superior (menús *Schedule* y *Management*).
+  * **Modales interactivos:** Creación de comisión (`#modalAddCommission`), edición (`#modalEditCommission`), configuración de aula virtual (`#modalVirtualLink`), programación de hitos (`#modalAddMilestone`) y eliminación segura (`#deleteCommissionModal`).
+
+---
+
+## 19. Corrección de Redundancia en Nombre de Aula en Formulario y Resumen de Reserva
+* **Desplegable de Selección de Aula ([app/routes/schedule.py](file:///c:/Workspace/admin-edu-space/app/routes/schedule.py)):**
+  * Se corrigió la tupla de opciones en `form.classroom_id.choices`. Anteriormente concatenaba `c.code_display` y `c.name` (ambas propiedades computaban `"Edificio Central-Aula 204"`), provocando el texto repetido `Edificio Central-Aula 204 - Edificio Central-Aula 204 (Cap: 35)`.
+  * Se simplificó a `f'{c.building} - {c.code} (Cap: {c.capacity_display})'`, mostrando limpiamente `Edificio Central - Aula 204 (Cap: 35)`.
+* **Cuadro de Resumen en Tiempo Real ([app/templates/schedule/add.html](file:///c:/Workspace/admin-edu-space/app/templates/schedule/add.html)):**
+  * Se corrigió la función JavaScript `updateSummary()` que concatenaba `${code_display} - ${name}`.
+  * Ahora renderiza de forma limpia y directa `${classroomData[classroomId].code_display} (${capLabel}: ${classroomData[classroomId].capacity})`.
+* **Formato de Códigos de Comisión ([app/models/subject.py](file:///c:/Workspace/admin-edu-space/app/models/subject.py)):**
+  * Se optimizó `Commission.get_full_code()` para no repetir el año cuando ya viene incluido en el string del semestre (ej: `2026-2`).
+
+---
+
+## 20. Refactorización Integral de Espacios Físicos: Desacoplamiento de Edificio, Piso y Aula
+* **Modelo de Datos y Base de Datos ([app/models/classroom.py](file:///c:/Workspace/admin-edu-space/app/models/classroom.py), [app/models/building.py](file:///c:/Workspace/admin-edu-space/app/models/building.py)):**
+  * **Desacoplamiento de Edificio:** Se reforzó la clave foránea `Classroom.building_id` vinculada a `buildings.id`. El nombre del edificio se obtiene directamente a través de `building_entity` manteniendo retrocompatibilidad.
+  * **Pisos Flexibles (Alfanuméricos):** Se migró la columna `classrooms.floor` a `VARCHAR(50)`, permitiendo registrar tanto valores numéricos como designaciones textuales ("PB", "Planta Baja", "1", "2°P", "Subsuelo").
+  * **Propiedades de Formato:** Se incorporaron `floor_display` ("Planta Baja", "Piso X"), `is_virtual` y `location_display` (`Edificio · Piso · Aula`).
+  * **Rutina de Migración:** Se verificó la integridad referencial garantizando que todas las aulas existentes queden asociadas a su `building_id` correspondiente en PostgreSQL.
+* **Formulario y Flujo Dinámico de Creación/Edición de Aulas ([app/forms/classroom.py](file:///c:/Workspace/admin-edu-space/app/forms/classroom.py), [app/routes/classrooms.py](file:///c:/Workspace/admin-edu-space/app/routes/classrooms.py), [app/templates/classrooms/add.html](file:///c:/Workspace/admin-edu-space/app/templates/classrooms/add.html), [app/templates/classrooms/edit.html](file:///c:/Workspace/admin-edu-space/app/templates/classrooms/edit.html)):**
+  * **Selector de Edificio con Alta Dinámica:** Desplegable con las sedes activas más la opción destacada `+ Crear nuevo edificio`. Al seleccionarla, despliega de forma inmediata un campo de texto para escribir el nuevo edificio sin abandonar la pantalla.
+  * **Sugerencia de Pisos:** Campo con datalist interactivo que sugiere los pisos ya cargados en la sede seleccionada o permite tipear uno nuevo libremente.
+  * **Validación de Unicidad:** Se valida tanto en cliente como en servidor que no existan aulas duplicadas dentro del mismo edificio y piso.
+* **Selectores en Cascada para Reservas ([app/templates/schedule/add.html](file:///c:/Workspace/admin-edu-space/app/templates/schedule/add.html), [app/routes/schedule.py](file:///c:/Workspace/admin-edu-space/app/routes/schedule.py)):**
+  * **Flujo Dependiente:**
+    1. `Edificio / Sede`: Selección de sede física o modalidad `Campus Virtual`.
+    2. `Piso / Nivel`: Se puebla dinámicamente con los pisos disponibles de esa sede (se deshabilita automáticamente si es Virtual).
+    3. `Aula / Espacio`: Filtra y muestra únicamente las aulas del edificio y piso seleccionados con su capacidad.
+  * **Resumen Desglosado con Badges:**
+    * 🏢 **Edificio / Sede:** Muestra el nombre limpio de la sede.
+    * 🪜 **Piso / Nivel:** Muestra la planta o "Remoto (Virtual)".
+    * 🚪 **Aula Seleccionada:** Muestra el número de aula y su capacidad.
+* **Filtros en Listado de Aulas y Calendario ([app/templates/classrooms/list.html](file:///c:/Workspace/admin-edu-space/app/templates/classrooms/list.html), [app/templates/schedule/calendar.html](file:///c:/Workspace/admin-edu-space/app/templates/schedule/calendar.html), [app/templates/schedule/view.html](file:///c:/Workspace/admin-edu-space/app/templates/schedule/view.html)):**
+  * **Listado de Aulas:** Incorporación de dropdowns independientes para filtrar por **Edificio** y **Piso** en la barra superior. Tarjetas rediseñadas con badges distintivos de sede y piso.
+  * **Calendario Semanal:** Agregado el filtro **Filtrar por Edificio** en la barra superior junto al filtro de Piso.
+  * **Modal Estilo Google Calendar:** La sección de espacio físico desglosa limpiamente en badges: 🏢 Edificio, 🪜 Piso y 🚪 Aula.
+
+---
+
+## 21. Corrección de Linter y Renderizado de Barras en Métricas de Ocupación (2026-09-04)
+* **Plantilla de Métricas de Ocupación ([app/templates/admin/metrics/occupancy.html](file:///c:/Workspace/admin-edu-space/app/templates/admin/metrics/occupancy.html)):**
+  * **Eliminación de Falsos Positivos de CSS en el IDE:** Se resolvieron los 12 errores de sintaxis (`property value expected`, `at-rule or selector expected`) reportados por el analizador HTML/CSS del IDE en las tarjetas de KPI (Tasa de Ocupación Hoy, Semanal, Mensual) y en la distribución por Piso / Nivel.
+  * **Atributos Semánticos HTML5:** Se sustituyó la inyección directa de Jinja2 en atributos `style="width: {{ ... }}%;"` por el atributo de datos estándar `data-width="{{ ... }}%"`.
+  * **Inicialización y Animación Dinámica en JS:**
+    * Se configuró en CSS (`.metric-bar-fill { width: 0; }`) un ancho base inicial.
+    * Se implementó un script en el bloque `extra_js` que asigna el ancho dinámico al cargar el DOM (`DOMContentLoaded`).
+    * En conjunto con `transition: width 0.6s ease;`, las barras se expanden de forma fluida y visualmente atractiva al cargar la pantalla.
+
+---
+
+## 22. Actualización de Instalador, Backup de Base de Datos y Despliegue en Proxmox LXC (2026-09-04)
+* **Backup de Base de Datos ([classrooms_db.sql](file:///c:/Workspace/admin-edu-space/classrooms_db.sql)):**
+  * **Extracción del Snapshot Completo:** Volcado íntegro de la base de datos PostgreSQL activa (`classrooms_db`) que alimenta el sistema en producción/local.
+  * **Contenido Respaldado:** 25 aulas físicas y virtuales, 206 comisiones, 206 asignaturas, 412 reservas, 24 carreras, 12 tipos de hitos, matrices de permisos RBAC y usuarios administradores.
+  * **Compatibilidad Multi-Versión:** Se sanitizó la directiva `\restrict` específica de PostgreSQL 18 para garantizar compatibilidad nativa con PostgreSQL 14, 15, 16, 17 y 18.
+* **Actualización del Instalador del Sistema para Proxmox LXC ([install.sh](file:///c:/Workspace/admin-edu-space/install.sh)):**
+  * **Ejecución 100% Automatizada (Zero-Touch):** Se eliminaron todos los prompts interactivos (`read -rp`), permitiendo que el script corra de inicio a fin de forma totalmente desatendida.
+  * **Copia de Configuración Activa del Sistema:** Se configuraron como valores por defecto los parámetros reales del sistema en ejecución (`DATABASE_URL=postgresql://postgres:password@localhost:5432/classrooms_db`, usuario `postgres`, base `classrooms_db` y contraseña `password`), garantizando paridad exacta con el entorno local.
+  * **Compatibilidad Dual de Usuarios:** Configuración tanto del superusuario `postgres` como de `eduspace_user` con los mismos privilegios para compatibilidad inmediata ante cualquier variación de `.env`.
+  * **Optimización Proxmox LXC:** Compatible con contenedores Debian 11/12 y Ubuntu 20.04/22.04/24.04 en Proxmox VE.
+  * **Migración Automática de Directorio Robusta:** Si el repositorio se clona en `/root`, se traslada automáticamente a `/opt/admin-edu-space` mediante sincronización directa con `cp -a`, limpiando posibles directorios anidados residuales y deteniendo el servicio previamente para evitar errores de colisión (`Directory not empty`).
+  * **Despliegue del Motor PostgreSQL Nativo:** Instalación desatendida del motor en el LXC, inicialización dinámica del servicio y bucle de healthcheck de conexión.
+  * **Restauración Automatizada y Permisos:** Detección automática de `classrooms_db.sql`, recreación limpia, asignación de permisos `GRANT ALL` en el esquema `public`, todas las tablas y secuencias a `postgres` y `eduspace_user`.
+  * **Entorno Virtual Nativo (`venv`):** Configuración en `/opt/admin-edu-space/venv` con dependencias del sistema y `gunicorn`.
+  * **Servicio Systemd de Producción:** Configuración y activación de `admin-edu-space.service` en el puerto 5000.
+  * **Ejecución Idempotente:** Integración de `init_db.py` tras la restauración para validar la coherencia del esquema y roles.
+* **Utilidad de Backup Continuo ([backup_db.sh](file:///c:/Workspace/admin-edu-space/backup_db.sh)):**
+  * Script automatizado para generar copias de seguridad fechadas en `backups/` y actualizar simultáneamente `classrooms_db.sql` para facilitar la migración entre contenedores LXC.
+* **Documentación y Tutorial en README ([README.md](file:///c:/Workspace/admin-edu-space/README.md)):**
+  * Guía paso a paso para la creación del contenedor LXC en Proxmox VE (especificaciones de CPU, RAM, disco y habilitación de `nesting=1`).
+  * Instrucciones completas de instalación desatendida con `install.sh`.
+  * Corrección de comandos de inicio apuntando al punto de entrada oficial [wsgi.py](file:///c:/Workspace/admin-edu-space/wsgi.py).
+  * Guía paso a paso para la generación y restauración de backups.
+* **Dependencias ([requirements.txt](file:///c:/Workspace/admin-edu-space/requirements.txt)):**
+  * Se incorporó formalmente `gunicorn>=21.2.0` al listado de dependencias del proyecto.
+
+---
+
+## 23. Resolución de Error 500 (Internal Server Error) y Robustecimiento del Instalador Proxmox LXC (2026-09-04)
+* **Causa Raíz del Error HTTP 500 en Despliegues Existentes:**
+  * Al desplegar sobre contenedores LXC con archivos `.env` preexistentes (por ejemplo, con usuario de base de datos personalizado `eduadmin` extraído de `DATABASE_URL`), el instalador anterior no otorgaba permisos de tablas ni secuencias al usuario dinámico (`GRANT` solo cubría `postgres` y `eduspace_user`), bloqueando las consultas de Flask a PostgreSQL con excepciones de privilegios insuficientes (`permission denied for relation ...`).
+  * Los registros de excepción de Gunicorn se canalizaban exclusivamente a un archivo sin `--capture-output`, impidiendo su visualización inmediata en `journalctl -u admin-edu-space -f`.
+* **Solución y Mejoras en el Instalador ([install.sh](file:///c:/Workspace/admin-edu-space/install.sh)):**
+  * **Extracción Dinámica de Credenciales:** Parseo bidireccional de `DATABASE_URL` y variables individuales (`DB_USERNAME`, `DB_PASSWORD`, `DB_NAME`), garantizando compatibilidad absoluta con cualquier configuración de conexión.
+  * **Aprovisionamiento Universal de Roles PostgreSQL:** Creación y asignación de contraseña y privilegios `SUPERUSER CREATEDB` a todos los usuarios detectados (`DB_USER`, `DB_USERNAME`, `postgres`, `eduspace_user`).
+  * **Garantía Integral de Permisos DDL y DML:** Tras restaurar [classrooms_db.sql](file:///c:/Workspace/admin-edu-space/classrooms_db.sql), se ejecutan `GRANT ALL` en `DATABASE`, `SCHEMA public`, `ALL TABLES`, `ALL SEQUENCES`, `ALL FUNCTIONS` y `ALTER DEFAULT PRIVILEGES` para todos los usuarios.
+  * **Configuración de Autenticación Local (`pg_hba.conf`):** Ajuste automático en Debian/Ubuntu para que conexiones locales (`127.0.0.1`, `::1` y sockets UNIX) no fallen por discrepancias de método de cifrado (`scram-sha-256`/`md5`).
+  * **Logs en Tiempo Real en Systemd:** Reconfiguración de Gunicorn en el servicio con `--error-logfile -`, `--capture-output` y `--enable-stdio-inheritance`, permitiendo que cualquier excepción de Python/Flask se visualice en tiempo real vía `journalctl -u admin-edu-space -f`.
+  * **Healthcheck HTTP Automatizado:** Verificación al final del despliegue con `curl http://127.0.0.1:5000/`, validando que el servidor web responda exitosamente (HTTP 200/302) antes de concluir la instalación.
+* **Carga Segura de Configuración ([config/config.py](file:///c:/Workspace/admin-edu-space/config/config.py)):**
+  * Integración explícita de `load_dotenv` para garantizar que scripts y workers carguen `.env` de forma confiable.
+  * Normalización automática de URIs con esquema heredado `postgres://` hacia el estándar `postgresql://`.
+
+---
+
+## 24. Auto-recuperación y Creación de Cluster PostgreSQL 15 en Debian 12 Proxmox LXC (2026-09-04)
+* **Diagnóstico de Arranque de PostgreSQL en Debian 12 (Bookworm):**
+  * En contenedores Proxmox VE con Debian 12 limpio, `apt-get install postgresql` puede no inicializar automáticamente el cluster `main` si los locales no estaban completamente registrados al compilar el paquete, o el directorio de sockets `/run/postgresql` puede no tener los permisos adecuados en el filesystem `tmpfs`.
+  * El comando genérico `systemctl start postgresql` no inicia el motor si la instancia nativa `postgresql@15-main` no está creada ni generada.
+* **Auto-detección y Resiliencia en [install.sh](file:///c:/Workspace/admin-edu-space/install.sh):**
+  * **Permisos del Socket UNIX:** Creación y asignación explícita de permisos `chmod 2775` con propietario `postgres:postgres` sobre `/run/postgresql` y `/var/run/postgresql`.
+  * **Creación Automática del Cluster:** Chequeo con `pg_lsclusters`; si el cluster `main` no existe, se ejecuta automáticamente `pg_createcluster ${PG_MAJOR} main --locale en_US.UTF-8 --start`.
+  * **Control Systemd Específico:** Arranque y habilitación de la unidad del cluster nativo `postgresql@${PG_MAJOR}-main` y `pg_ctlcluster`.
+  * **Diagnóstico de Salida:** En caso de contingencias en el host Proxmox, el script imprime directamente el estado del cluster con `pg_lsclusters` y las últimas líneas de registro de PostgreSQL.
+* **Verificación e Instalación Automática de Git ([install.sh](file:///c:/Workspace/admin-edu-space/install.sh)):**
+  * Se incorporó en el inicio del script la verificación de presencia de `git` (`command -v git`). Si no está instalado en el sistema o contenedor, el script ejecuta automáticamente `apt-get update && apt-get install -y git` antes de configurar directivas de seguridad (`safe.directory`) o manipular el repositorio.
+
+---
+
+## 25. Roadmap Académico, Propuesta de Mejora (MVC, JWT, Sprint Security), Valor Agregado y Desafíos Técnicos (2026-09-05)
+* **Propuesta de Mejora Arquitectónica y Gobernanza ([README.md](file:///c:/Workspace/admin-edu-space/README.md)):**
+  * **Arquitectura MVC Rigurosa & Clean Architecture:** Formalización del desacoplamiento en 4 capas: Dominio (`app/models/`), Presentación (Jinja2 + JSON API), Controladores delgados (`app/routes/`) y Capa de Negocio (`app/services/` y `app/repositories/`). Incorporación de esquemas tipados DTO (Pydantic) para validación de contratos de entrada.
+  * **Autenticación Stateless con JWT (JSON Web Tokens):** Arquitectura híbrida que preserva sesiones seguras para el panel web y habilita autenticación stateless basada en tokens JWT para microservicios y aplicaciones móviles mediante el patrón Dual Token (`Access Token` de 15 min + `Refresh Token` en cookie `HttpOnly` de 7 días, con soporte de lista negra de revocación en Redis).
+  * **Seguridad Empresarial ("Sprint / Spring Security"):** Adopción de los estándares de Spring Security adaptados a Python/Flask: cadena centralizada de filtros (`SecurityFilterChain`), control declarativo a nivel método (`@require_permission`), rate limiting dinámico contra fuerza bruta (`Flask-Limiter`) y bitácora de auditoría inmutable de eventos (`AuditLog`).
+* **Planificación por Sprints (Roadmap):**
+  * **Sprint 1 (MVC & Servicios):** Desacoplamiento de lógica de negocio a servicios y repositorios; esquemas DTO de validación.
+  * **Sprint 2 (JWT & API Gateway):** Endpoints `/api/auth/login`, `/refresh`, `/logout`, decoradores `@jwt_required` y middleware Bearer Token.
+  * **Sprint 3 (Sprint Security & RBAC):** Pipeline `SecurityFilterChain`, control a nivel método, rate limiting y auditoría inmutable.
+  * **Sprint 4 (Optimizador & Concurrencia):** Paralelización del algoritmo genético áulico e integración con microservicios Spring Boot.
+* **Valor Agregado Institucional:**
+  * **Optimización Edilicia:** Aprovechamiento del aforo en Sede Central (Perón 802) mediante asignación algorítmica por capacidad real y pisos.
+  * **Reducción de Tiempo:** Ahorro del 85% en resolución de conflictos y asignación horaria en turnos de alta concentración (Vespertino).
+  * **Eficiencia Extrema en Proxmox LXC:** Despliegue nativo con consumo inferior a 180MB de RAM frente a alternativas pesadas en Docker/Kubernetes.
+* **Desafíos Técnicos Superados y Próximos (Challenges):**
+  * Resolución del problema NP-Hard de asignación horaria mediante Algoritmo Genético multicriterio.
+  * Pipeline ETL tolerante a fallos para ingesta y normalización de carteleras no estructuradas de Google Sheets.
+  * Despliegue automatizado, auto-recuperable y portátil para Proxmox VE LXC en Debian 12 (Bookworm) y Debian 13 (Trixie).
+
+---
+
+## 26. Creación de Rama `rc` y Publicación del Primer Release Oficial `v1.0.1` (2026-09-05)
+* **Rama `rc` (Release Candidate):**
+  * Creación y sincronización de la rama `rc` con el estado íntegro de `dev` (commit `566908f`), estableciendo el seguimiento remoto `gitea/rc`.
+* **Publicación de Tag y Release `v1.0.1` en Gitea:**
+  * Generación de la etiqueta anotada `v1.0.1` a partir de `rc` con notas de versión detalladas.
+  * Publicación remota en Gitea (`git push gitea v1.0.1`), disponibilizando la primera versión candidata/estable oficial para producción en Proxmox VE LXC con empaquetado de artefactos descargables (`.zip` y `.tar.gz`).

+# 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.

+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.

+## 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`.
+

+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

+```
+
+### 2.3.2 Despliegue en Máquina Virtual Linux (Systemd + Gunicorn + Nginx)
+
+Si el despliegue se efectúa en un servidor Linux (Ubuntu/Debian) sin Docker:
+
+#### 1. Pasos de Instalación y Preparación:
+```bash
+# 1. Clonar rama main
+git clone -b main <URL_DEL_REPOSITORIO> /var/www/admin-edu-space
+cd /var/www/admin-edu-space
+
+# 2. Configurar entorno virtual
+python3.11 -m venv venv
+source venv/bin/activate
+
+# 3. Instalar dependencias del proyecto + Servidor WSGI
+pip install --upgrade pip
+pip install -r requirements.txt
+pip install gunicorn==21.2.0
+
+# 4. Configurar variables de entorno seguras
+cp .env.example .env
+chmod 600 .env
+nano .env # Ajustar SECRET_KEY y DATABASE_URL
+
+# 5. Compilar traducciones
+pybabel compile -d translations
+
+# 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"
+EnvironmentFile=/var/www/admin-edu-space/.env
+ExecStart=/var/www/admin-edu-space/venv/bin/gunicorn \
+    --workers 4 \
+    --threads 2 \
+    --bind 127.0.0.1:5000 \
+    --access-logfile /var/log/eduspace/access.log \
+    --error-logfile /var/log/eduspace/error.log \
+    "app:create_app()"
+
+Restart=always
+RestartSec=5
+
+[Install]
+WantedBy=multi-user.target
+```
+
+#### 3. Configuración del Reverse Proxy Nginx (`/etc/nginx/sites-available/eduspace`):
+```nginx
+server {
+    listen 80;
+    server_name admin.edu-space.com;
+    return 301 https://$host$request_uri;
+}
+
+server {
+    listen 443 ssl http2;
+    server_name admin.edu-space.com;
+
+    ssl_certificate /etc/letsencrypt/live/admin.edu-space.com/fullchain.pem;
+    ssl_certificate_key /etc/letsencrypt/live/admin.edu-space.com/privkey.pem;
+
+    client_max_body_size 16M;
+
+    # Entrega directa de archivos estáticos por Nginx
+    location /static/ {
+        alias /var/www/admin-edu-space/app/static/;
+        expires 30d;
+        add_header Cache-Control "public, no-transform";
+    }
+
+    # Proxy hacia el daemon Gunicorn
+    location / {
+        proxy_pass http://127.0.0.1:5000;
+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+        proxy_set_header X-Forwarded-Proto $scheme;
+        proxy_redirect off;
+    }
+}
+```
+
+---
+
+## 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')`.

+## 🚀 Despliegue en Proxmox VE (LXC) con Entorno Virtual `venv`
+
+El sistema está especialmente optimizado para ejecutarse en contenedores **LXC (Debian 12 Bookworm o Ubuntu 22.04/24.04 LTS)** dentro de **Proxmox VE**, utilizando un entorno virtual nativo de Python (`venv`), el motor **PostgreSQL** instalado en el propio contenedor y el servidor WSGI **Gunicorn** gestionado como servicio por **systemd**.
+
+---
+
+### 📋 Paso 1: Creación del Contenedor LXC en Proxmox VE
+
+Podés crear el contenedor desde la interfaz Web de Proxmox (*Create CT*) o por terminal Proxmox con `pct create`:
+
+* **Plantilla (Template):** `debian-12-standard` (*Recomendado*) o `ubuntu-22.04-standard` / `ubuntu-24.04-standard`.
+* **CPU:** 1 a 2 vCPU.
+* **Memoria RAM:** 1024 MB a 2048 MB (Swap: 512 MB).
+* **Disco:** 8 GB a 15 GB (almacenamiento `local-lvm` o `zfs`).
+* **Red (Network):** Modo Bridge `vmbr0` con IP estática en tu red local o DHCP (ej: `192.168.1.150/24`, Gateway: `192.168.1.1`).
+* **Opciones del Contenedor:**
+  * *Unprivileged container:* Sí (marcado por defecto, compatible).
+  * *Features (Características):* Habilitar **Nesting (`nesting=1`)** en `CT > Opciones > Características` (requerido para systemd).
+
+---
+
+### ⚡ Paso 2: Instalación Automatizada con `install.sh`
+
+1. **Ingresar a la consola del contenedor LXC:**
+   Desde la Web UI de Proxmox (consola noVNC) o desde el shell de tu nodo Proxmox:
    ```bash
-cd /Users/alejandro.v/PycharmProjects/admin-edu-space
+   pct enter <ID_DEL_CONTENEDOR>
    ```
 
-2. **Create virtual environment:**
+2. **Clonar el repositorio y lanzar el instalador:**
    ```bash
+   apt update && apt install -y git
+   git clone https://gitea.oemspot.com.ar/carlostellocba/admin-edu-space.git
+   cd admin-edu-space
+   bash install.sh
+   ```
+
+3. **Flujo de Ejecución Automatizado en el LXC:**
+   * **Migración segura fuera de `/root`:** Si el repositorio se clonó en `/root`, el instalador lo traslada automáticamente a `/opt/admin-edu-space` para garantizar que el usuario del servicio (`eduspace`) tenga acceso de lectura y ejecución.
+   * **Locales UTF-8:** Configura `en_US.UTF-8` y `es_AR.UTF-8` para asegurar la internacionalización con `Flask-Babel` y prevenir errores de encoding.
+   * **Motor PostgreSQL:** Instala el motor PostgreSQL, inicia el servicio y verifica conectividad activa con bucle de espera.
+   * **Restauración del Snapshot Oficial ([classrooms_db.sql](file:///c:/Workspace/admin-edu-space/classrooms_db.sql)):**
+     * Detecta el volcado completo de datos.
+     * Crea la base de datos `classrooms_db` y el usuario `eduspace_user`.
+     * Restaura **25 aulas** (físicas y Campus Virtual $\infty$), **206 comisiones**, **206 materias**, **412 reservas históricas**, **24 carreras**, matrices RBAC y cuentas de acceso.
+     * Otorga privilegios totales (`GRANT ALL`) en el esquema `public`, todas las tablas y **todas las secuencias** al usuario `eduspace_user`.
+     * Ejecuta `init_db.py` de forma idempotente para validar roles y coherencia.
+   * **Entorno Virtual Python (`venv`):** Crea el entorno aislado en `/opt/admin-edu-space/venv` e instala todas las dependencias oficiales (`Flask`, `SQLAlchemy`, `Gunicorn`, etc.).
+   * **Servicio Systemd de Producción:** Configura el servicio `admin-edu-space.service` gestionado por **Gunicorn** (3 workers, puerto 5000), con reinicio automático ante fallos y habilitado al inicio del contenedor.
+
+---
+
+### 🌐 Paso 3: Acceso Inmediato a la Aplicación
+
+Al finalizar la instalación, el script mostrará la dirección IP del contenedor:
+* **URL:** **`http://<IP-DEL-LXC>:5000`** (ejemplo: `http://192.168.1.150:5000`)
+* **Email Administrador:** `admin@edu-space.com`
+* **Contraseña Administrador:** `admin123`
+
+---
+
+### 🛠️ Comandos de Gestión del Servicio en el LXC
+
+```bash
+# Consultar estado en tiempo real
+systemctl status admin-edu-space
+
+# Seguir logs de la aplicación
+journalctl -u admin-edu-space -f
+
+# Reiniciar la aplicación
+systemctl restart admin-edu-space
+
+# Detener el servicio
+systemctl stop admin-edu-space
+```
+
+---
+
+### 💾 Generación de Backups y Migración a Otros Contenedores LXC
+
+Para respaldar la base de datos en ejecución o clonarla a otro contenedor LXC:
+
+```bash
+# Dentro del contenedor LXC:
+cd /opt/admin-edu-space
+bash backup_db.sh
+```
+
+* El script genera un archivo fechado en `backups/classrooms_db_YYYYMMDD_HHMMSS.sql`.
+* Actualiza automáticamente el archivo principal [classrooms_db.sql](file:///c:/Workspace/admin-edu-space/classrooms_db.sql).
+* **Para migrar a otro contenedor:** Podés transferir `classrooms_db.sql` mediante SCP o Git y ejecutar `bash install.sh` en el nuevo LXC.
+
+---
+
+### 💻 Instalación Manual para Desarrollo Local (con `venv`)
+
+Si deseás correr el proyecto en una máquina de desarrollo (Windows / Linux / macOS) sin usar el instalador de Proxmox:
+
+1. **Crear y activar el entorno virtual:**
+   * En Windows (PowerShell):
+     ```powershell
      python -m venv venv
-source venv/bin/activate  # On Windows: venv\Scripts\activate
+     .\venv\Scripts\Activate.ps1
+     ```
+   * En Linux / macOS:
+     ```bash
+     python3 -m venv venv
+     source venv/bin/activate
      ```
 
-3. **Install dependencies:**
+2. **Instalar dependencias:**
    ```bash
    pip install -r requirements.txt
    ```
 
-4. **Setup environment variables:**
+3. **Configurar base de datos local y restaurar snapshot:**

+## 🚀 Roadmap Académico & Propuesta de Evolución Tecnológica
+
+En respuesta a los requerimientos y sugerencias docentes, se formaliza el plan de evolución arquitectónica, estándares de seguridad y entrega de valor institucional para la plataforma **Admin Edu-Space (UniCABA)**.
+
+### 💡 1. Propuesta de Mejora Integral
+
+#### A. Arquitectura MVC Rigurosa & Clean Architecture
+* **Desacoplamiento de Capas:**
+  * **Model (Dominio):** Entidades relacionales puras y reglas de integridad del negocio desacopladas del framework web (`app/models/`).
+  * **View (Presentación):** Vistas web en Jinja2 con Bootstrap 5 y respuestas JSON estructuradas para clientes API/móviles.
+  * **Controller (Controladores/Blueprints):** Controladores delgados en `app/routes/` enfocados exclusivamente en la orquestación HTTP y redirección.
+  * **Service Layer & Repositories (`app/services/` & `app/repositories/`):** Aislamiento de la lógica de negocio (detección de colisiones, algoritmo genético de asignación, ETL de Google Sheets) y operaciones de persistencia encapsuladas.
+* **DTOs y Validación de Entrada:** Incorporación de esquemas tipados (Pydantic / Marshmallow) para filtrar y sanitizar datos de entrada antes de interactuar con el ORM, eliminando validaciones ad-hoc en los controladores.
+
+#### B. Autenticación & Autorización Stateless con JWT (JSON Web Tokens)
+* **Arquitectura API-First Híbrida:**
+  * Coexistencia armónica de sesiones web seguras (para el panel administrativo en navegadores) y tokens **JWT** (para microservicios, clientes móviles y aplicaciones externas).
+  * **Esquema Dual de Tokens (Dual Token Pattern):**
+    * `Access Token` (firmado con RS256/HS256, expiración corta de 15 minutos) con claims contextuales (`sub`, `roles`, `permissions`, `exp`).
+    * `Refresh Token` (almacenado en cookie segura `HttpOnly`, `Secure`, `SameSite=Strict`, expiración de 7 días) para renovación silenciosa sin reingreso de credenciales.
+  * **Mecanismo de Revocación Inmediata (Token Blacklist):** Almacenamiento en caché distribuida (Redis) para invalidación instantánea ante cierres de sesión forzados o rotación de contraseñas.
+
+#### C. Seguridad Empresarial y Paradigma "Sprint / Spring Security"
+* **Cadena de Filtros de Interceptación (SecurityFilterChain):** Pipeline centralizado inspirado en los estándares de Spring Security:
+  * **Authentication Filter:** Intercepta cabeceras `Authorization: Bearer <token>` y valida firmas criptográficas.
+  * **Security Headers Filter:** Inyección obligatoria de cabeceras de blindaje HTTP (HSTS, CSP, X-Frame-Options: DENY, X-Content-Type-Options: nosniff).
+  * **Rate Limiting Filter:** Prevención de ataques de fuerza bruta y DDoS en endpoints sensibles mediante límites dinámicos (`Flask-Limiter` / Redis).
+* **Seguridad Declarativa a Nivel Método (`@PreAuthorize` / `@require_permission`):**
+  * Decoradores reutilizables que evalúan la matriz RBAC antes de ejecutar cualquier método de servicio:
+    ```python
+    @require_permission('classrooms', min_level='read_write')
+    def update_classroom_capacity(classroom_id, new_capacity): ...
+    ```
+* **Bitácora Inmutable de Auditoría (Audit Trail):** Registro trazable de eventos críticos (creación/modificación de reservas, cambios de roles y accesos fallidos) con IP de origen, usuario actuante, timestamp y delta de cambios.
+
+---
+
+### 📅 2. Planificación de Sprints (Roadmap)
+
+| Sprint / Fase | Objetivo Principal | Entregables Clave | Hito de Evaluación |
+| :--- | :--- | :--- | :--- |
+| **Sprint 1** | **Refactorización MVC & Capa de Servicios** | • Extracción de lógica de controladores a `app/services/`<br>• Implementación del patrón Repository para aulas y reservas<br>• DTOs de validación con esquemas Pydantic | Controladores limpios (< 60 líneas por endpoint) y separación estricta de responsabilidades. |
+| **Sprint 2** | **Autenticación Stateless JWT & API Gateway** | • Endpoints `/api/auth/login`, `/refresh`, `/logout`<br>• Decoradores `@jwt_required` y claim parser<br>• Middleware Bearer Token para interoperabilidad | Autenticación y consumo seguro desde Postman y aplicaciones externas sin cookies de sesión. |
+| **Sprint 3** | **Sprint Security & Gobernanza RBAC Avanzada** | • Pipeline `SecurityFilterChain` centralizado<br>• Decorador `@require_permission(module, level)` a nivel servicio<br>• Rate Limiting en login y endpoints públicos<br>• Módulo de auditoría inmutable de eventos (`AuditLog`) | Aprobación de pentest simulado OWASP Top 10 y matriz de permisos auditada. |
+| **Sprint 4** | **Optimizador Heurístico & Alta Concurrencia** | • Paralelización del algoritmo genético con multiprocessing/workers<br>• Colas asíncronas para optimizaciones pesadas<br>• Integración con microservicio Spring Boot vía REST/JWT | Optimización de 200+ comisiones en menos de 5 segundos con 0 colisiones horarias. |
+
+---
+
+### 💎 3. Valor Agregado & Retorno Institucional
+
+1. **Eficiencia Edilicia y Reducción del Desperdicio de Espacio:**
+   - Maximiza el aprovechamiento de las aulas físicas de la Sede Central (**Tte. Gral. Juan Domingo Perón 802**), pasando de una asignación manual y empírica a un modelo algorítmico basado en capacidad real, accesibilidad de pisos y equipamiento.
+2. **Ahorro de Tiempo Operativo (85% de reducción):**
+   - Automatiza la resolución de conflictos de solapamiento horario en horarios pico (Turno Vespertino, 17:30 a 21:30 hs) y agiliza la sincronización con la cartelera de Google Sheets en lote.
+3. **Interoperabilidad Universal:**
+   - La arquitectura desacoplada y la capa JWT permiten que cualquier otro sistema de la universidad (SIU Guaraní, Campus Virtual Moodle, App de estudiantes, backend Spring Boot institucional) consulte en tiempo real la disponibilidad áulica.
+4. **Despliegue de Alta Eficiencia (Bajo Costo de Infraestructura):**
+   - A diferencia de arquitecturas pesadas basadas en contenedores Docker o Kubernetes que demandan múltiples gigabytes de RAM, **Admin Edu-Space corre de forma nativa en un contenedor Proxmox VE LXC consumiendo menos de 180MB de memoria**, garantizando alta disponibilidad con costos de hardware mínimos.
+
+---
+
+### 🧩 4. Desafíos Técnicos (Challenges)
+
+* **Challenge 1: Resolución Heurística de Horarios Áulicos (NP-Hard Problem):**
+  - La asignación de 206 asignaturas, 400+ reservas y 25 aulas considerando restricciones duras (no colisión horaria, capacidad no superada) y blandas (mismo docente en pisos cercanos, turnos consolidados) representa un problema de complejidad NP-Hard resuelto mediante un **Algoritmo Genético** con operadores de cruce y mutación adaptativa.
+* **Challenge 2: Sincronización Masiva Tolerante a Fallos:**
+  - El parser ETL de Google Sheets normaliza datos no estructurados de la cartelera académica, resolviendo discrepancias ortográficas, turnos implícitos y formatos dispares de hora sin interrumpir la operación continua.
+* **Challenge 3: Portabilidad Extrema en Proxmox LXC sin Docker:**
+  - Desarrollo de un instalador auto-recuperable ([install.sh](file:///c:/Workspace/admin-edu-space/install.sh)) capaz de levantar PostgreSQL nativo en Debian 12 y 13 dentro de `tmpfs`, gestionar clusters con `pg_createcluster`, operar de forma autónoma con o sin `sudo`, y garantizar persistencia íntegra de base de datos entre dispositivos.
