+# Plan de Actualizaciones Mayores - Gamilit & Trading-Platform
+
+## Resumen Ejecutivo
+
+Este plan detalla la migración de dependencias con breaking changes significativos para los proyectos **gamilit** y **trading-platform**.
+
+---
+
+## 1. ZOD 3.x → 4.x (GAMILIT Frontend)
+
+### Estado Actual
+- **Versión actual**: 4.1.12 (ya está en v4 en package.json)
+- **Archivos afectados**: ~30+ archivos con schemas de validación
+- **Uso principal**: `@hookform/resolvers/zod` para validación de formularios
+
+### Breaking Changes Relevantes
+| Cambio | Impacto | Acción Requerida |
+|--------|---------|------------------|
+| `message` → `error` param | Alto | Buscar y reemplazar |
+| `.default()` behavior change | Medio | Verificar schemas con defaults |
+| `ZodError.errors` → `ZodError.issues` | Bajo | Verificar manejo de errores |
+| Import paths (`zod/v4`) | Bajo | Mantener `zod` (es v4 default) |
+
+### Análisis del Código
+```typescript
+// Patrones encontrados que necesitan revisión:
+z.string().min(1, 'El correo electrónico es requerido')  // OK - sin cambios
+z.enum(['student', 'admin_teacher'], { message: '...' }) // CAMBIO: message → error
+.refine((val) => val === true, { message: '...' })       // OK - refine sigue igual
+```
+
+### Tareas
+1. Ejecutar codemod `npx zod-v3-to-v4`
+2. Buscar `{ message:` en schemas y cambiar a `{ error:`
+3. Verificar schemas con `.default()` o `.catch()`
+4. Ejecutar tests y build
+
+### Riesgo: BAJO (ya está en v4, solo ajustes menores)
+
+---
+
+## 2. STRIPE 14.x → 20.x (Trading-Platform Backend)
+
+### Estado Actual
+- **Versión actual**: ^14.7.0
+- **Archivos afectados**: 3 archivos en `/modules/payments/`
+- **API Version usada**: `2023-10-16`
+
+### Breaking Changes Relevantes
+| Cambio | Impacto | Acción Requerida |
+|--------|---------|------------------|
+| API Version update | Alto | Actualizar apiVersion |
+| Checkout Session behavior | Medio | Verificar subscription flow |
+| `total_count` deprecated on lists | Bajo | No usado en código |
+
+### Análisis del Código
+```typescript
+const stripe = new Stripe(config.stripe?.secretKey, {
+  apiVersion: '2023-10-16',  // CAMBIO: Actualizar a '2024-12-18.acacia' o latest
+});
+
+// Patrones usados:
+stripe.customers.create()           // OK
+stripe.checkout.sessions.create()   // REVISAR: subscription behavior
+stripe.subscriptions.update()       // OK
+stripe.billingPortal.sessions.create() // OK
+```
+
+### Tareas
+1. Actualizar `stripe` a ^20.0.0
+2. Actualizar `apiVersion` a versión compatible
+3. Verificar webhook signature handling
+4. Testear flujo de checkout completo
+5. Verificar `stripe.promotionCodes.list()` sigue funcionando
+
+### Riesgo: MEDIO (requiere testing de flujo de pagos)
+
+---
+
+## 3. REDIS 4.x → 5.x (Trading-Platform Backend)
+
+### Estado Actual
+- **Versión actual**: ^4.6.10
+- **Archivos afectados**: 0 (no se encontró uso activo)
+- **Nota**: La dependencia está declarada pero no hay imports de `redis`
+
+### Análisis
+```bash
+grep -rn "from ['\"']redis['\"']" src/  # Sin resultados
+grep -rn "createClient" src/             # Sin resultados
+```
+
+### Breaking Changes Relevantes (si se usara)
+| Cambio | Impacto |
+|--------|---------|
+| `client.QUIT()` → `client.close()` | N/A |
+| `client.disconnect()` → `client.destroy()` | N/A |
+| Iterator changes (SCAN, etc.) | N/A |
+
+### Recomendación
+**OPCIÓN A**: Remover la dependencia (no está en uso)
+**OPCIÓN B**: Actualizar a v5 para cuando se necesite
+
+### Riesgo: NINGUNO (no hay código que usar redis)
+
+---
+
+## 4. JEST 29.x → 30.x (Ambos Proyectos)
+
+### Estado Actual
+- **Versión actual**: ^29.7.0 (gamilit backend, trading-platform backend)
+- **Archivos afectados**: Archivos de configuración jest y todos los tests
+
+### Breaking Changes Relevantes
+| Cambio | Impacto | Acción Requerida |
+|--------|---------|------------------|
+| Node 14/16 dropped | Ninguno | Ya usamos Node 18+ |
+| jsdom 21→26 | Medio | Revisar mocks de window.location |
+| `--testPathPattern` → `--testPathPatterns` | Bajo | Actualizar scripts |
+| `genMockFromModule` removed | Bajo | Buscar y reemplazar |
+| Snapshot changes (Error.cause) | Bajo | Actualizar snapshots |
+
+### Análisis del Código
+```bash
+# Buscar uso de APIs deprecadas
+grep -rn "genMockFromModule" __tests__/  # Verificar
+grep -rn "toBeCalled()" __tests__/        # Cambiar a toHaveBeenCalled()
+```
+
+### Tareas
+1. Actualizar `jest` a ^30.0.0
+2. Actualizar `ts-jest` a versión compatible
+3. Actualizar `@types/jest` a ^30.0.0
+4. Buscar y reemplazar `genMockFromModule` → `createMockFromModule`
+5. Actualizar snapshots: `npm test -- -u`
+6. Verificar mocks de `window.location` en frontend tests
+
+### Riesgo: BAJO-MEDIO (principalmente snapshots)
+
+---
+
+## 5. VITEST 3.x → 4.x (Gamilit Frontend)
+
+### Estado Actual
+- **Versión actual**: ^3.2.4
+- **Archivos afectados**: Configuración vitest y tests de frontend
+
+### Análisis
+Vitest 4 tiene cambios menores. La mayoría son mejoras de performance.
+
+### Riesgo: BAJO
+
+---
+
+## Plan de Ejecución por Fases
+
+### FASE 1: Bajo Riesgo (Ejecutar Primero)
+1. **Redis**: Remover dependencia no usada
+2. **Zod**: Ajustes menores de sintaxis (message → error)
+
+### FASE 2: Riesgo Medio
+3. **Jest/Vitest**: Actualizar testing frameworks
+4. **Stripe**: Actualizar con testing exhaustivo
+
+### FASE 3: Opcional
+5. Otras dependencias menores identificadas
+
+---
+
+## Prompts para Subagentes
+
+### Subagente 1: Migración Zod
+```
+TAREA: Migrar schemas de Zod en gamilit/apps/frontend
+
+1. Ejecutar: npx zod-v3-to-v4 --dry-run primero
+2. Buscar patrones: { message: en archivos *Schema*.ts
+3. Reemplazar { message: por { error: en z.enum() y similares
+4. NO cambiar .refine() - esos siguen usando message
+5. Verificar: npm run build && npm test
+
+Archivos clave:
+- src/shared/schemas/auth.schemas.ts
+- src/features/mechanics/**/\*Schemas.ts
+- src/services/api/schemas/*.ts
+```
+
+### Subagente 2: Limpieza Redis
+```
+TAREA: Remover dependencia redis no usada en trading-platform/apps/backend
+
+1. Verificar que no hay imports de 'redis' en src/
+2. Remover "redis": "^4.6.10" de package.json
+3. Ejecutar npm install
+4. Verificar build: npm run build
+```
+
+### Subagente 3: Migración Jest
+```
+TAREA: Migrar Jest 29→30 en trading-platform/apps/backend
+
+1. Actualizar package.json:
+   - "jest": "^30.0.0"
+   - "ts-jest": "^29.3.0" (compatible con jest 30)
+   - "@types/jest": "^30.0.0"
+
+2. Buscar y reemplazar en __tests__/:
+   - genMockFromModule → createMockFromModule
+   - toBeCalled() → toHaveBeenCalled()
+
+3. Actualizar jest.config.js si necesario
+
+4. Ejecutar: npm test -- -u (actualizar snapshots)
+5. Verificar todos los tests pasan
+```
+
+### Subagente 4: Migración Stripe
+```
+TAREA: Migrar Stripe 14→20 en trading-platform/apps/backend
+
+1. Actualizar package.json: "stripe": "^20.0.0"
+2. npm install
+
+3. Actualizar src/modules/payments/services/stripe.service.ts:
+   - Cambiar apiVersion: '2023-10-16' → '2024-12-18.acacia'
+
+4. Verificar que estos métodos siguen funcionando:
+   - stripe.customers.create()
+   - stripe.checkout.sessions.create()
+   - stripe.subscriptions.update()
+   - stripe.billingPortal.sessions.create()
+   - stripe.webhooks.constructEvent()
+
+5. npm run build
+6. Documentar cualquier cambio de API necesario
+```
+
+---
+
+## Validación Post-Migración
+
+Para cada proyecto:
+```bash
+# 1. Limpiar node_modules
+rm -rf node_modules package-lock.json
+npm install
+
+# 2. Verificar vulnerabilidades
+npm audit
+
+# 3. Build
+npm run build
+
+# 4. Lint
+npm run lint
+
+# 5. Tests
+npm test
+
+# 6. Dev server (verificación manual)
+npm run dev
+```
+
+---
+
+## Decisión Final
+
+| Dependencia | Acción | Prioridad | Subagente |
+|-------------|--------|-----------|-----------|
+| redis | REMOVER | Alta | #2 |
+| zod | AJUSTAR | Media | #1 |
+| jest | ACTUALIZAR | Media | #3 |
+| stripe | ACTUALIZAR | Baja | #4 |
+| vitest | POSTERGAR | Baja | - |
+
+**Nota**: Stripe se posterga porque el riesgo de romper pagos en producción es alto y requiere testing exhaustivo con sandbox.

 ## Uso
 
-### Sistema de Orquestación
-Los agentes cargan automáticamente las directivas de `core/orchestration/directivas/` al inicializar. Cada proyecto puede extender (pero no reducir) estas directivas.
+### Importar Utilidades
 
-### Módulos Reutilizables
-Los módulos en `core/modules/` son dependencias compartidas que pueden ser importadas por cualquier proyecto.
+```typescript
+// En cualquier proyecto del workspace
+import { formatDate, slugify, isEmail } from '@core/modules/utils';
 
-### Estándares
-Los estándares en `core/standards/` definen los mínimos de calidad para todos los proyectos.
+// O importar específico
+import { formatToISO, addDays } from '@core/modules/utils/date.util';
+```
+
+### Importar Constantes
+
+```typescript
+import { UserStatus, PaymentStatus } from '@core/constants';
+import { EMAIL_REGEX, UUID_REGEX } from '@core/constants/regex.constants';
+```
+
+### Importar Tipos
+
+```typescript
+import { ApiResponse, PaginatedResponse } from '@core/types';
+import { BaseEntity, Address } from '@core/types/common.types';
+```
+
+## Módulos Disponibles
+
+### Utils (`@core/modules/utils`)
+
+| Archivo | Funciones | Descripción |
+|---------|-----------|-------------|
+| `date.util.ts` | formatDate, addDays, diffInDays, etc. | Manipulación de fechas |
+| `string.util.ts` | slugify, capitalize, truncate, etc. | Manipulación de strings |
+| `validation.util.ts` | isEmail, isUUID, isStrongPassword, etc. | Validaciones |
+

+
+| Archivo | Contenido |
+|---------|-----------|
+| `enums.constants.ts` | UserStatus, PaymentStatus, NotificationType, etc. |
+| `regex.constants.ts` | EMAIL_REGEX, UUID_REGEX, PHONE_REGEX, etc. |
+
+### Types (`@core/types`)
+
+| Archivo | Tipos |
+|---------|-------|
+| `api.types.ts` | ApiResponse, PaginatedResponse, ErrorCodes |

+# Guía de Alineación de Verticales con ERP-Core
+
+**Versión:** 1.0.0
+**Fecha:** 2025-12-09
+**Propósito:** Estándar para mantener verticales alineadas con erp-core
+
+---
+
+## 1. Arquitectura Base
+
+### ERP-Core como Fundación
+
+Todas las verticales heredan de **erp-core** que provee:
+
+| Schema | Tablas | Propósito |
+|--------|--------|-----------|
+| auth | 26 | Autenticación, MFA, OAuth, API Keys, roles, permisos |
+| core | 12 | Partners, catálogos, UoM, monedas, secuencias |
+| financial | 15 | Contabilidad, facturas, pagos, asientos |
+| inventory | 20 | Productos, stock, valoración FIFO/AVCO, lotes |
+| purchase | 8 | Órdenes de compra, proveedores |
+| sales | 10 | Ventas, cotizaciones, equipos de venta |
+| projects | 10 | Proyectos, tareas, dependencias |
+| analytics | 7 | Contabilidad analítica, centros de costo |
+| system | 13 | Mensajes, notificaciones, logs, auditoría |
+| billing | 11 | SaaS/Suscripciones (opcional) |
+| crm | 6 | Leads, oportunidades (opcional) |
+| hr | 6 | Empleados, contratos, ausencias |
+| **TOTAL** | **144** | |
+
+### Variable RLS Estándar
+
+```sql
+current_setting('app.current_tenant_id', true)::UUID
+```
+
+**IMPORTANTE:** Todas las verticales DEBEN usar esta variable exacta para RLS.
+

+      - nombre_tabla_2
+```
+
+---
+
+## 4. Reglas de Nomenclatura DDL
+
+### Archivos SQL
+
+```
+00-extensions.sql          # Extensiones PostgreSQL
+01-create-schemas.sql      # CREATE SCHEMA IF NOT EXISTS
+02-rls-functions.sql       # Funciones de contexto RLS
+03-{dominio}-tables.sql    # Tablas por dominio
+04-{dominio}-tables.sql
+...
+99-seed-data.sql           # Datos iniciales
+```
+
+### Tablas
+
+- Usar snake_case: `service_orders`, `order_items`
+- Prefijo de schema obligatorio en FK: `auth.users`, `core.partners`
+- Columnas de auditoría estándar:
+  ```sql
+  created_at TIMESTAMPTZ NOT NULL DEFAULT NOW(),
+  created_by UUID REFERENCES auth.users(id),
+  updated_at TIMESTAMPTZ,
+  updated_by UUID REFERENCES auth.users(id),
+  deleted_at TIMESTAMPTZ,
+  deleted_by UUID REFERENCES auth.users(id)
+  ```
+
+### RLS Policy
+
+```sql
+CREATE POLICY tenant_isolation_{tabla} ON {schema}.{tabla}
+  FOR ALL USING (tenant_id = current_setting('app.current_tenant_id', true)::UUID);
+```
+
+---
+
+## 5. Estado de Verticales Actuales
+
+| Vertical | Estado | DDL | Backend | Frontend | Próximo Paso |
+|----------|--------|-----|---------|----------|--------------|
+| **Construcción** | 35% | ✅ 7 archivos | Parcial | Estructura | Completar backend |
+| **Mecánicas Diesel** | 95% | ✅ 6 archivos | Estructura | Estructura | Iniciar Sprint 1 |
+| **Clínicas** | 25% | ❌ Pendiente | No iniciado | No iniciado | Crear DDL |
+| **Retail** | 25% | ❌ Pendiente | No iniciado | No iniciado | Crear DDL |
+| **Vidrio Templado** | 25% | ❌ Pendiente | No iniciado | No iniciado | Crear DDL |
+
+---
+
+## 6. Checklist de Alineación
+
+### Antes de iniciar desarrollo:
+
+- [ ] `herencia_core.tablas_heredadas` = 144
+- [ ] `herencia_core.version_core` = "1.2.0"
+- [ ] `herencia_core.variable_rls` = "app.current_tenant_id"
+- [ ] Los 12 schemas heredados están documentados
+- [ ] `HERENCIA-ERP-CORE.md` existe en database/
+- [ ] DDL usa `current_setting('app.current_tenant_id', true)::UUID`
+- [ ] FK a auth.tenants y auth.users (NO core.*)
+
+### Validación de DDL:
+
+```bash
+# Verificar variable RLS correcta
+grep -r "current_tenant_id" database/init/*.sql
+
+# Verificar NO usar variable incorrecta
+grep -r "current_tenant'" database/init/*.sql  # Debe retornar vacío
+
+# Verificar FK correctas
+grep -r "auth.tenants" database/init/*.sql
+grep -r "auth.users" database/init/*.sql
+```
+
+---
+
+## 7. Proceso de Actualización
+
+Cuando erp-core se actualice:
+
+1. Verificar cambios en `INVENTARIO-OBJETOS-BD.yml`
+2. Actualizar `tablas_heredadas` si cambió
+3. Actualizar `version_core`
+4. Revisar si hay nuevos schemas
+5. Actualizar `DATABASE_INVENTORY.yml` de cada vertical
+6. Verificar compatibilidad de DDL existente
+
+---
+
+## 8. Contacto y Soporte

+### Schema: clinica (13 tablas)
+
+| Tabla | Módulo | Descripción |
+|-------|--------|-------------|
+| specialties | CL-002 | Catálogo de especialidades médicas |
+| doctors | CL-002 | Médicos (extiende hr.employees) |
+| patients | CL-001 | Pacientes (extiende core.partners) |
+| patient_contacts | CL-001 | Contactos de emergencia |
+| patient_insurance | CL-001 | Información de seguros |
+| appointment_slots | CL-002 | Horarios disponibles |

+| diagnoses | CL-003 | Diagnósticos (CIE-10) |
+| prescriptions | CL-003 | Recetas médicas |
+| prescription_items | CL-003 | Medicamentos en receta |
+
+## ENUMs
+
+| Enum | Valores |
+|------|---------|
+| appointment_status | scheduled, confirmed, in_progress, completed, cancelled, no_show |
+| patient_gender | male, female, other, prefer_not_to_say |
+| blood_type | A+, A-, B+, B-, AB+, AB-, O+, O-, unknown |
+| consultation_status | draft, in_progress, completed, cancelled |
+
+## Row Level Security
+
+Todas las tablas tienen RLS habilitado con aislamiento por tenant:
+
+```sql
+tenant_id = current_setting('app.current_tenant_id', true)::UUID
+```
+
+## Consideraciones de Seguridad
+
+- **NOM-024-SSA3-2012**: Expediente clínico electrónico
+- **Datos sensibles**: medical_records, consultations requieren encriptación
+- **Auditoría completa**: Todas las tablas tienen campos de auditoría
