+# Módulo Auth
+
+**Epic:** OQI-001 - Fundamentos Auth
+**Progreso:** 70%
+**Responsable:** Backend + Frontend Teams
+
+## Descripción
+
+El módulo de autenticación proporciona un sistema completo de registro, login, recuperación de contraseña, y gestión de sesiones para la plataforma de trading. Incluye soporte para autenticación social (Google, Facebook, Apple) y por teléfono, además de características avanzadas de seguridad como gestión de dispositivos y sesiones activas.
+
+Este módulo es crítico para toda la plataforma, ya que controla el acceso a todas las funcionalidades y gestiona la identidad del usuario a través de JWT tokens con auto-refresh.
+
+## Componentes

+- `Register.tsx` - Formulario de registro de nuevos usuarios con validación en tiempo real
+- `ForgotPassword.tsx` - Flujo de recuperación de contraseña mediante email
+- `ResetPassword.tsx` - Página para establecer nueva contraseña con token de verificación
+- `VerifyEmail.tsx` - Confirmación de email para activación de cuenta
+- `AuthCallback.tsx` - Callback handler para proveedores OAuth (Google, Facebook, Apple)
+- `SecuritySettings.tsx` - Panel de configuración de seguridad y gestión de sesiones

+
+```tsx
+import { Login, Register } from '@/modules/auth';
+import { useAuthStore } from '@/stores/authStore';
+
+// Uso en router
+ } />
+ } />
+
+// Uso de store
+function MyComponent() {
+ const { user, isAuthenticated, login, logout } = useAuthStore();
+
+ const handleLogin = async () => {
+ await login('user@example.com', 'password123');
+ };
+
+ return (
+
+ {isAuthenticated ? (
+ <>
+
Bienvenido, {user?.email}
+
Cerrar sesión
+ >
+ ) : (
+
Iniciar sesión
+ )}
+
+ );
+}
+```
+
+## Características Principales
+
+### Autenticación Social

+
+### Autenticación por Teléfono
+- SMS verification con código de 6 dígitos
+- Rate limiting para prevenir abuso
+- Soporte internacional de números
+
+### Seguridad
+- JWT tokens con expiración configurable
+- Refresh tokens para renovación automática
+- Device tracking y fingerprinting
+- Gestión de sesiones concurrentes
+- IP logging para auditoría
+
+### Gestión de Sesiones
+- Visualización de dispositivos activos
+- Revocación individual de sesiones
+- Notificaciones de nuevos inicios de sesión
+- Timeout automático por inactividad
+

+# OQI-005: Análisis de Gaps - Funcionalidades Faltantes
+
+**Módulo:** OQI-005 (pagos-stripe)
+**Fecha:** 2026-01-25
+**Criticidad:** Las siguientes features no están implementadas pero serían valiosas para UX completa
+
+---
+
+## Gap 1: Refunds UI (Devoluciones)
+
+**Prioridad:** Alta
+**Complejidad:** Media
+**Impacto:** UX, Legal, Soporte
+
+### Descripción del Gap
+
+Actualmente no existe:
+- UI para iniciar devoluciones de pagos
+- Panel de historial de reembolsos procesados
+- Validación de período de devolución (ej: 30 días)
+- Estados de devolución (pending, processing, completed, failed)
+- Notificaciones al usuario cuando devolución se procesa
+
+### Casos de Uso
+
+```
+1. Usuario solicita reembolso de suscripción
+ ├── Verifica si está dentro de período permitido (14 días)
+ ├── Selecciona razón de devolución
+ ├── Backend procesa via Stripe API
+ ├── Estado se actualiza a "pending"
+ └── Usuario notificado cuando se completa (1-3 días)
+
+2. Usuario ve historial de reembolsos
+ ├── Tabla en Billing.tsx → Nueva tab "Reembolsos"
+ ├── Muestra:
+ │ ├── Fecha de solicitud
+ │ ├── Monto reembolsado
+ │ ├── Motivo
+ │ ├── Estado (pending/completed/failed)
+ │ └── Método devolución (mismo método pago original)
+ └── Filtros: status, fecha range
+
+3. Administrador revisa reembolso rechazado
+ ├── Dashboard de admin ver motivo rechazo
+ ├── Opción de re-procesar
+ └── Notificar usuario
+```
+
+### Componentes Necesarios
+
+```typescript
+// 1. RefundRequestModal (modal para solicitar devolución)
+interface RefundRequestModalProps {
+ isOpen: boolean;
+ onClose: () => void;
+ subscriptionId: string;
+ daysRemaining: number; // Días dentro período permitido
+ refundableAmount: number;
+ onSuccess?: () => void;
+}
+
+// 2. RefundList (tabla historial reembolsos)
+interface RefundListProps {
+ subscriptionId?: string;
+ compact?: boolean;
+ itemsPerPage?: number;
+}
+
+// 3. RefundDetail (modal detalle reembolso)
+interface RefundDetailProps {
+ refundId: string;
+ onClose: () => void;
+}
+```
+
+### Endpoint Backend Requerido
+
+```
+POST /payments/refunds
+├── Body: { subscriptionId, amount, reason, requestedAt }
+├── Valida: Dentro de período permitido (30 días default)
+├── Respuesta: { id, status, amount, reason, processedAt? }
+└── Webhook: refund.completed → Actualizar wallet usuario
+
+GET /payments/refunds
+├── Query params: subscriptionId, status, dateRange
+└── Respuesta: Paginated list
+
+GET /payments/refunds/{id}
+├── Detalle de reembolso
+└── Historial de actualizaciones
+
+DELETE /payments/refunds/{id}
+├── Solo si status=pending
+└── Cancelar devolución pendiente
+```
+
+### Lógica de Negocio
+
+```
+Período Devolución: 14 días desde primera facturación
+├── Free trial: +7 días adicionales
+├── Payment failed: No aplica devolución
+└── Upgrade/downgrade: Proporcional a días usados
+
+Estados:
+├── pending: Enviada a Stripe, sin procesar
+├── processing: Stripe la está procesando
+├── completed: Completada, fondos devueltos
+├── failed: Rechazada por banco/Stripe
+└── cancelled: Usuario canceló solicitud
+
+Reglas:
+├── 1 reembolso/cliente/30 días (máximo)
+├── Monto: hasta 100% de suscripción
+└── Notificación: Email cuando se complete
+```
+
+### Estimación Esfuerzo
+
+- **Backend:** 8-12 horas (Stripe API integration, webhook, DB)
+- **Frontend UI:** 6-8 horas (modal, tabla, detalle)
+- **Testing:** 4-6 horas
+- **Documentación:** 2-3 horas
+- **Total:** ~20-29 horas
+
+---
+
+## Gap 2: Histórico de Cambios de Plan
+
+**Prioridad:** Media
+**Complejidad:** Baja
+**Impacto:** UX, Auditoría, Soporte
+
+### Descripción del Gap
+
+Actualmente no existe:
+- Visualización del historial de cambios de plan
+- Fechas de cambio y razones
+- Comparativa plan anterior vs nuevo
+- Créditos/cargos aplicados en cada cambio
+- Timeline visual de evolución de suscripción
+
+### Casos de Uso
+
+```
+1. Usuario revisa su historial de planes
+ ├── Nueva tab en Billing: "Historial de Planes"
+ ├── Timeline/tabla mostrando:
+ │ ├── Fecha cambio
+ │ ├── Plan anterior → Plan nuevo
+ │ ├── Precio anterior → Precio nuevo
+ │ ├── Crédito prorrateo (si aplica)
+ │ ├── Cargo adicional (si aplica)
+ │ └── Razón del cambio (upgrade/downgrade/etc)
+ └── Botones: Ver detalles, Descargar recibo
+
+2. Usuario entiende su evolución de suscripción
+ ├── Cuándo cambió de Free → Pro
+ ├── Cuándo hizo upgrade Pro → Enterprise
+ └── Visualizar inversión total en plataforma
+
+3. Soporte consulta historial cliente
+ ├── Dashboard admin con historia completa
+ ├── Auditoría de cambios (quién, cuándo)
+ └── Facilita resolución de disputas
+```
+
+### Componentes Necesarios
+
+```typescript

+```
+
+### Lógica de Negocio
+
+```
+Cambio de Plan:
+├── Fecha: Inmediata (upgrade) o fin de período (downgrade)
+├── Crédito: Prorrateo por días no usados del plan anterior
+├── Cargo: Diferencia (si upgrade) o crédito (si downgrade)
+├── Factura: Nueva línea en siguiente ciclo o invoice immediata
+└── Notificación: Confirmación al usuario
+
+Datos Calculados:
+├── changeType: Compara precio plan anterior vs nuevo
+├── Prorration: (daysRemaining / daysInPeriod) * planPrice
+└── Timeline: Mostrar cuando cambios se aplicaron
+```
+
+### Estimación Esfuerzo
+
+- **Backend:** 4-6 horas (queries, DB si no existe tabla)
+- **Frontend UI:** 4-6 horas (timeline, tabla, modal)
+- **Testing:** 2-3 horas
+- **Documentación:** 1-2 horas
+- **Total:** ~11-17 horas

+## Gap 3: Preview de Factura
+
+**Prioridad:** Media

+
+### Descripción del Gap
+
+Actualmente no existe:
+- Preview de factura ANTES de completar pago
+- Visualización de items que se facturarán
+- Cálculo claro de subtotal, impuestos, descuentos
+- Confirmación de direcciones de facturación
+- Mostrar si hay cambios desde checkout anterior
+
+### Casos de Uso
+
+```

+```
+
+### Estimación Esfuerzo
+
+- **Backend:** 6-8 horas (cálculo impuestos, endpoints)
+- **Frontend UI:** 4-6 horas (modal, forms, updates)
+- **Tax Integration:** 2-4 horas (si usa servicio externo)
+- **Testing:** 3-4 horas
+- **Documentación:** 1-2 horas
+- **Total:** ~16-24 horas
+
+---
+
+## Gap 4: Payment Intent Flow (Completo)
+
+**Prioridad:** Alta (Seguridad)
+**Complejidad:** Alta
+**Impacto:** Seguridad, PCI-DSS Compliance
+
+### Descripción del Gap
+
+Actualmente:
+- ✅ Usa Stripe Hosted Checkout (seguro, delegado)
+- ❌ NO implementa Payment Intent flow en cliente
+- ❌ Métodos de pago sin tokenización Stripe.js
+- ❌ NO soporta 3D Secure / SCA en cliente (delegado a backend)
+- ❌ NO maneja tarjetas declinadas gracefully
+
+### Casos de Uso
+
+```
+1. Usuario completa checkout con tarjeta nueva (Hosted Checkout)
+ ├── Redirección a Stripe
+ ├── Stripe maneja validación, 3DS, etc
+ ├── Redirige back a CheckoutSuccess
+ └── ✅ Funciona (implementado)
+
+2. Usuario agrega método de pago desde Billing
+ ├── Abre formulario PaymentMethodForm
+ ├── ❌ Envía número de tarjeta SIN tokenizar
+ ├── Backend debería rechazar (PCI risk)
+ └── Debería usar Stripe.js Elements
+
+3. Usuario paga con saved payment method
+ ├── No aplica (solo checkout con hosted)
+ └── Si se implementa: requiere Payment Intent
+
+4. 3D Secure required
+ ├── Backend detecta SCA required
+ ├── Devuelve clientSecret
+ ├── ❌ Frontend no maneja confirmación
+ ├── Debería usar Stripe.js confirmCardPayment
+ └── Mostrar modal de autenticación
+```
+
+### Componentes Necesarios
+
+```typescript
+// 1. StripeProvider (wrappear app)
+import { Elements } from '@stripe/react-stripe-js';
+import { loadStripe } from '@stripe/js';
+
+const stripePromise = loadStripe(STRIPE_PUBLIC_KEY);
+
+// 2. PaymentMethodForm refactorizado
+interface PaymentMethodFormProps {
+ onSuccess: (paymentMethodId: string) => void;
+ onCancel?: () => void;
+ onError?: (error: string) => void;
+ setAsDefault?: boolean;
+}
+
+// 3. PaymentIntentModal (para confirmar 3DS)
+interface PaymentIntentModalProps {
+ clientSecret: string;
+ onSuccess: () => void;
+ onError: (error: string) => void;
+}
+```
+
+### Cambios Necesarios
+
+```typescript
+// BEFORE (Inseguro)
+const handleSubmit = async (e) => {
+ const result = await addPaymentMethod({
+ type: 'card',
+ card: {
+ number: cardNumber, // ❌ PCI risk
+ exp_month: expiry.split('/')[0],
+ exp_year: 2000 + parseInt(expiry.split('/')[1]),
+ cvc: cvc, // ❌ PCI risk
+ },
+ });
+};
+
+// AFTER (Seguro con Stripe.js)
+const { stripe, elements } = useStripe();
+
+const handleSubmit = async (e) => {
+ const cardElement = elements.getElement(CardElement);
+
+ // Crear payment method en Stripe (tokenizado)
+ const { error, paymentMethod } = await stripe.createPaymentMethod({
+ type: 'card',
+ card: cardElement,
+ });
+
+ if (!error) {
+ // Enviar token, no tarjeta
+ const result = await addPaymentMethod(paymentMethod.id);
+ }
+};
+```
+
+### Endpoint Backend Requerido
+
+```
+POST /payments/methods
+├── Body: { paymentMethodId, setAsDefault }
+├── paymentMethodId: Token Stripe (ej: pm_1234567890)
+├── Almacena en Stripe + DB
+└── ✅ Compliant PCI-DSS
+
+POST /payments/subscriptions/{id}/confirm-payment
+├── Body: { clientSecret, paymentMethodId }
+├── Si requiere SCA: Procesa autenticación
+├── Respuesta: { success, paymentStatus }
+└── Usado para 3D Secure flow
+```
+
+### Estimación Esfuerzo
+
+- **Backend:** 4-6 horas (validar tokens, SCA handling)
+- **Frontend Stripe.js:** 8-10 horas (Elements, intent confirmation)
+- **Testing (incluye SCA test):** 6-8 horas
+- **Documentación:** 2-3 horas
+- **Total:** ~20-27 horas
+
+---
+
+## Gap 5: Apple Pay / Google Pay
+
+**Prioridad:** Baja
+**Complejidad:** Media
+**Impacto:** UX, Conversión (móvil)
+
+### Descripción del Gap
+
+Actualmente no existe soporte para:
+- Apple Pay (en iOS/macOS)
+- Google Pay (en Android/Chrome)
+- Botones "Pay with X" en checkout
+
+### Estimación Esfuerzo
+
+- **Backend:** 2-4 horas (endpoint validation)
+- **Frontend:** 6-8 horas (Stripe Payment Request Button)
+- **Testing:** 4-6 horas (necesita dispositivos)
+- **Total:** ~12-18 horas
+
+---
+
+## Gap 6: Retry Logic para Pagos Fallidos
+
+**Prioridad:** Media
+**Complejidad:** Media
+**Impacto:** Retención, Ingresos
+
+### Descripción del Gap
+
+Actualmente:
+- ❌ No hay reintentos automáticos de pagos fallidos
+- ❌ No hay notificación al usuario cuando falla
+- ❌ No hay UI para re-procesar pago manual
+- ❌ No hay webhook handling para payment_intent.payment_failed
+
+### Casos de Uso
+
+```
+1. Suscripción tiene status "past_due"
+ ├── Payment falló (tarjeta rechazada, fondos insuficientes)
+ ├── Sistema envía email al usuario
+ ├── Usuario puede ver deuda pendiente en Billing
+ ├── Usuario puede:
+ │ ├── Actualizar método de pago
+ │ └── Click "Reintentar pago"
+ └── Stripe reintenta automáticamente (3 veces en 3 días)
+
+2. Dashboard muestra estado "Pago Pendiente"
+ ├── Badge rojo en SubscriptionCard
+ ├── Info: "Tenemos un problema con tu pago"
+ ├── Botones:
+ │ ├── Actualizar método de pago
+ │ └── Reintentar ahora
+ └── Link a portal Stripe
+```
+
+### Endpoints Requeridos
+
+```
+POST /payments/subscription/{id}/retry-payment
+├── Reintenta el pago pendiente
+├── Requiere valid payment method
+└── Respuesta: { success, newStatus, nextRetryDate? }
+
+GET /payments/failed-payments
+├── Listar pagos fallidos del usuario
+└── Respuesta: Array de intentos fallidos con razones
+```
+
+### Estimación Esfuerzo
+
+- **Backend:** 4-6 horas (retry logic, webhooks)
+- **Frontend:** 3-4 horas (UI, forms)
+- **Testing:** 2-3 horas
+- **Total:** ~9-13 horas
+
+---
+
+## Priorización Recomendada
+
+### Fase 1 (MVP - 2-3 semanas)
+1. **Preview de Factura** (16-24 hrs) - Mejor UX antes de pagar
+2. **Retry Logic** (9-13 hrs) - Aumenta retención
+
+### Fase 2 (3-4 semanas)
+3. **Refunds UI** (20-29 hrs) - Cumplimiento legal, UX completa
+4. **Histórico Cambios Plan** (11-17 hrs) - Soporte + auditoría
+
+### Fase 3 (2-3 semanas)
+5. **Payment Intent Flow** (20-27 hrs) - Seguridad PCI-DSS
+6. **Apple Pay / Google Pay** (12-18 hrs) - Conversión móvil
+
+---
+
+## Impacto de No Implementar
+
+| Gap | Riesgo | Impacto |
+|-----|--------|--------|
+| Refunds | Legal/Cumplimiento | Posibles multas/disputas |
+| Historial Cambios | Soporte | Tickets más complejos |
+| Preview Factura | UX | Menor confianza en checkout |
+| Payment Intent | Seguridad | PCI-DSS non-compliant |
+| Apple/Google Pay | Conversión | Pérdida clientes móviles |
+| Retry Logic | Ingresos | Pérdida 5-10% suscriptores |
+
+---

+# OQI-005: Integración Stripe - Análisis Técnico
+
+**Módulo:** OQI-005 (pagos-stripe)
+**Enfoque:** Frontend Stripe integration, flujos de checkout, métodos de pago
+**Fecha:** 2026-01-25
+
+---
+
+## 1. Integración Stripe - Visión General
+
+### Estado Actual
+- ✅ **Checkout Modal:** Stripe Hosted Checkout (redirect)
+- ✅ **Métodos de Pago:** Gestión tarjetas via API backend
+- ✅ **Webhooks:** Procesados en backend (no visible en frontend)
+- ⚠️ **Stripe.js Elements:** NO implementado (formulario manual sin tokenización)
+- ⚠️ **3D Secure / SCA:** Delegado a backend/Stripe
+
+### Flujo de Pago Principal
+
+```
+Usuario selecciona plan
+ ↓
+Pricing.tsx → handleSelectPlan()
+ ↓
+payment.service.createCheckoutSession(planId, interval)
+ ↓
+POST /payments/checkout → Backend crea Stripe Session
+ ↓
+Respuesta: { sessionId, url }
+ ↓
+window.location.href = url (redirige a Stripe Hosted Checkout)
+ ↓
+Usuario completa pago en Stripe
+ ↓
+Stripe redirige a CheckoutSuccess page con session_id param
+ ↓
+CheckoutSuccess espera 2s y llama fetchCurrentSubscription()
+ ↓
+Dashboard actualizado con nueva suscripción
+```
+
+---
+
+## 2. Flujos de Checkout Implementados
+
+### 2.1 Checkout Sesión (Subscripción)
+
+**Página:** `Pricing.tsx`
+
+```typescript
+const handleSelectPlan = async (planId: string, selectedInterval: PlanInterval) => {
+ try {
+ const checkoutUrl = await createCheckoutSession(planId, selectedInterval);
+ window.location.href = checkoutUrl; // Stripe Hosted Checkout
+ } catch (error) {
+ console.error('Error creating checkout session:', error);
+ }
+};
+```
+
+**Endpoint Backend:**
+- `POST /payments/checkout`
+- **Params:** `{ planId, billingCycle (monthly/yearly), successUrl, cancelUrl }`
+- **Response:** `{ sessionId, url }`
+
+**Flujo:**
+1. Obtiene lista de planes desde store
+2. Filtra planes activos
+3. Ordena por precio
+4. Renderiza 4 tarjetas (grid responsivo)
+5. Al hacer click → crea sesión checkout
+6. Redirige a Stripe Hosted Checkout
+
+**Características:**
+- Toggle mensual/anual con visualización de descuento
+- Badge "Más Popular" en plan principal
+- Badge "Plan Actual" si ya tiene suscripción
+- Cálculo mensual equivalente (price/12 para anual)
+- Tabla comparativa características
+- FAQ preguntas frecuentes
+
+### 2.2 Cambio de Plan (Upgrade/Downgrade)
+
+**Componente:** `SubscriptionUpgradeFlow.tsx`
+
+**Flujo 3 Pasos:**
+
+```
+PASO 1: Seleccionar Plan
+├── Lista planes activos
+├── Muestra precio y 4 características
+├── Indica si es Upgrade/Downgrade
+└── Click → Fetch preview
+
+PASO 2: Previsualizar Cambios
+├── Comparación plan actual vs nuevo
+├── Cálculo prorrateo (si upgrade → inmediato, si downgrade → fin período)
+├── Resumen financiero:
+│ ├── Crédito prorrateo (si aplica)
+│ ├── Precio nuevo plan
+│ └── Monto total a pagar/acreditar
+├── Fecha efectiva
+└── Botón confirmar
+
+PASO 3: Éxito
+├── Confirmación visual
+├── Nombre plan nuevo
+└── Botón cerrar
+```
+
+**Endpoint Backend:**
+- `POST /payments/subscription/change-plan`
+- **Params:** `{ planId, billingCycle }`
+- **Response:** `{ id, status, amount, currentPeriodEnd, ... }`
+
+**Nota:** Preview es MOCK en frontend (no implementado en backend)
+
+```typescript
+export async function previewSubscriptionChange(
+ planId: string,
+ interval: PlanInterval,
+ couponCode?: string
+): Promise {
+ // Returns hardcoded mock - needs backend implementation
+ return {
+ subtotal: 0,
+ discount: 0,
+ tax: 0,
+ total: 0,
+ currency: 'USD',
+ interval,
+ };
+}
+```
+
+### 2.3 Cancelación de Suscripción
+
+**Página:** `Billing.tsx` → Tab "Resumen"
+
+**Endpoint Backend:**
+- `POST /payments/subscription/cancel`
+- **Params:** `{ immediately: boolean }`
+- **Response:** `{ id, status: 'canceled', canceledAt, ... }`
+
+**Comportamiento:**
+- Por defecto `immediately = false` (cancela al final del período)
+- UI muestra aviso: "Tu suscripción se cancelará el [fecha]"
+- Opción "Reactivar" disponible antes de la fecha de cancelación
+
+**Endpoint Backend (Reactivar):**
+- `POST /payments/subscription/resume`
+- **Response:** `{ id, status: 'active', ... }`
+
+---
+
+## 3. Métodos de Pago
+
+### 3.1 Agregar Método de Pago
+
+**Componente:** `PaymentMethodForm.tsx`
+
+**Flujo:**
+```
+Formulario Manual (sin Stripe.js)
+├── Card Number (validación Luhn, detección brand)
+├── Cardholder Name
+├── Expiry (MM/YY)
+├── CVC (3-4 dígitos)
+└── Checkbox "Set as Default"
+
+Click "Add Card"
+ ↓
+Validaciones locales:
+ ├── Nombre no vacío
+ ├── Número 13-19 dígitos
+ ├── Fecha válida (MM 1-12, no expirada)
+ └── CVC 3-4 dígitos
+ ↓
+POST /payments/methods
+ ↓
+Response: { id, brand, last4, expiryMonth, expiryYear, isDefault }
+```
+
+**Problemas de Seguridad:**
+- ⚠️ **NO usa Stripe.js Elements** - tarjeta se envía al backend en texto plano (NO compliant PCI DSS en frontend)
+- ✅ Debería usar: `@stripe/react-stripe-js` con `CardElement`
+- ✅ Token debe generarse en frontend y pasarse al backend
+
+**Validaciones Locales:**
+```typescript
+const formatCardNumber = (value: string) => {
+ const v = value.replace(/\s+/g, '').replace(/[^0-9]/gi, '');
+ const matches = v.match(/\d{4,16}/g);
+ const match = (matches && matches[0]) || '';
+ const parts = [];
+ for (let i = 0, len = match.length; i < len; i += 4) {
+ parts.push(match.substring(i, i + 4));
+ }
+ return parts.length ? parts.join(' ') : value;
+};
+
+const getCardType = (number: string): string => {
+ const cleanNumber = number.replace(/\s/g, '');
+ if (/^4/.test(cleanNumber)) return 'Visa';
+ if (/^5[1-5]/.test(cleanNumber)) return 'Mastercard';
+ if (/^3[47]/.test(cleanNumber)) return 'Amex';
+ if (/^6(?:011|5)/.test(cleanNumber)) return 'Discover';
+ return 'Card';
+};
+```
+
+### 3.2 Gestionar Métodos de Pago
+
+**Componente:** `PaymentMethodsList.tsx`
+
+**Funcionalidades:**
+- Listar métodos guardados (brand + last4)
+- Badge "Default" si es método predeterminado
+- Alerta si vence en 3 meses
+- Alerta si ya está expirado (desactivado)
+- Menú dropdown (Set as Default, Remove)
+- Modal de confirmación antes de eliminar
+
+**Endpoints:**
+| Acción | Método | Endpoint |
+|--------|--------|----------|
+| Listar | GET | `/payments/methods` |
+| Agregar | POST | `/payments/methods` |
+| Establecer Default | POST | `/payments/methods/default` |
+| Eliminar | DELETE | `/payments/methods/{id}` |
+
+**Lógica Expiración:**
+```typescript
+const isExpiringSoon = (expMonth: number, expYear: number) => {
+ const now = new Date();
+ const expDate = new Date(expYear, expMonth - 1);
+ const threeMonths = new Date();
+ threeMonths.setMonth(threeMonths.getMonth() + 3);
+ return expDate <= threeMonths && expDate >= now;
+};
+
+const isExpired = (expMonth: number, expYear: number) => {
+ const now = new Date();
+ const expDate = new Date(expYear, expMonth);
+ return expDate < now;
+};
+```
+
+### 3.3 Portal de Stripe
+
+**Implementación:** `Billing.tsx` → Botón "Portal de Stripe"
+
+**Endpoint Backend:**
+- `POST /payments/billing-portal`
+- **Params:** `{ returnUrl }`
+- **Response:** `{ url }`
+
+**Uso:**
+```typescript
+const handleOpenBillingPortal = async () => {
+ try {
+ const { url } = await createPortalSession(returnUrl);
+ window.location.href = url;
+ } catch (error) {
+ console.error('Error opening portal:', error);
+ }
+};
+```
+
+**Funcionalidades en Portal (delegadas a Stripe):**
+- Cambiar método de pago predeterminado
+- Actualizar información de facturación
+- Cambiar plan
+- Cancelar/reactivar suscripción
+- Descargar facturas
+- Ver historial de pagos
+
+---
+
+## 4. Flujos Post-Checkout
+
+### 4.1 Checkout Success
+
+**Página:** `CheckoutSuccess.tsx`
+
+```
+URL: /checkout/success?session_id=cs_...
+
+Renderiza:
+├── Loading (2 segundos - espera webhooks Stripe)
+├── Entonces:
+│ ├── CheckCircle icon (verde)
+│ ├── "Pago Exitoso"
+│ ├── Detalles suscripción:
+│ │ ├── Plan name
+│ │ ├── Ciclo (mensual/anual)
+│ │ ├── Estado (Activo)
+│ │ └── Próxima factura
+│ └── Botones:
+│ ├── Ir al Dashboard
+│ └── Ver Detalles de Facturación
+└── Session ID visible (debug)
+```
+
+**Lógica:**
+```typescript
+useEffect(() => {
+ const timer = setTimeout(async () => {
+ try {
+ await fetchCurrentSubscription(); // Refresca desde backend
+ } catch (error) {
+ console.error('Error fetching subscription:', error);
+ } finally {
+ setLoading(false);
+ }
+ }, 2000); // Espera webhooks Stripe
+ return () => clearTimeout(timer);
+}, [fetchCurrentSubscription]);
+```
+
+### 4.2 Checkout Cancel
+
+**Página:** `CheckoutCancel.tsx`
+
+```
+URL: /checkout/cancel?reason=expired|user_cancelled
+
+Renderiza:
+├── XCircle icon (gris)
+├── "Pago Cancelado"
+├── Mensaje basado en reason:
+│ ├── reason=expired: "La sesión ha expirado"
+│ └── default: "Has cancelado el proceso"
+├── Help section:
+│ ├── Si tarjeta rechazada → intenta otro método
+│ ├── Contactar soporte
+│ └── Pagos seguros via Stripe
+└── Botones:
+ ├── Volver a Planes
+ └── Contactar Soporte
+```
+
+---
+
+## 5. Cupones de Descuento
+
+**Componente:** `CouponForm.tsx`
+
+**Flujo:**
+```
+Input código (uppercase)
+ ↓
+Click "Apply" o Enter
+ ↓
+POST /payments/coupons/validate
+ ↓
+Respuesta:
+{
+ valid: boolean,
+ discountType: 'percent' | 'fixed',
+ discountValue: number,
+ message?: string
+}
+ ↓
+Si válido:
+├── Calcula descuento en monto
+├── Muestra badge verde con código
+├── Botón X para quitar
+└── onApply(couponInfo)
+
+Si inválido:
+└── Muestra error
+```
+
+**Estados:**
+- No aplicado: Form vacío
+- Validando: Spinner
+- Aplicado: Badge verde con descuento
+- Error: Mensaje rojo
+
+**Tipos de Descuento:**
+```typescript
+interface CouponInfo {
+ code: string;
+ valid: boolean;
+ discountType: 'percent' | 'fixed';
+ discountValue: number;
+ discountAmount?: number; // Calculado en frontend
+ expiresAt?: string;
+ minPurchase?: number;
+ maxUses?: number;
+ usedCount?: number;
+}
+```
+

+
+## 8. Seguridad - Notas Críticas
+
+### Cumplimiento PCI DSS
+| Item | Estado | Nota |
+|------|--------|------|
+| Tokenización Stripe | ⚠️ Parcial | Backend maneja, frontend envía números en texto |
+| Stripe.js Elements | ❌ No | Necesario para compliant |
+| 3D Secure / SCA | ✅ Backend | Manejado por Stripe + backend |
+| HTTPS | ✅ Asumido | URL origen es HTTPS |
+| Input Validation | ✅ Parcial | Cliente-side Luhn check presente |
+| Rate Limiting | ❌ Desconocido | Debe estar en backend |
+
+### Recomendaciones
+1. **Implementar Stripe.js Elements** para PaymentMethodForm
+2. **Usar Payment Intent API** con confirmación cliente
+3. **Validar CSRF tokens** en todos los POST
+4. **Implementar retry logic** en checkouts fallidos
+5. **Auditar logs** de transacciones en backend
+
+---
+
+## 9. Estado de Implementación
+
+### Completo ✅
+- Checkout sesión (Hosted Checkout)
+- Cambio de plan (preview MOCK)
+- Cancelación/reactivación suscripción
+- Gestión métodos de pago
+- Cupones descuento
+- Portal Stripe
+
+### Parcial ⚠️
+- Validación cupones (backend debe validar más)
+- Preview cambio plan (MOCK, no real)
+- Métodos de pago (falta Stripe.js Elements)
+
+### No Implementado ❌
+- Refunds UI
+- Histórico cambios de plan
+- Preview factura antes de pagar
+- Payment Intent flow completo
+- Apple Pay / Google Pay
