+# Auditoría y Mejoras del Sistema Nexus POS — 15 de junio de 2026
+
+## Resumen ejecutivo
+
+Se realizó una revisión completa del sistema Nexus POS enfocada en corregir errores críticos y mayores, eliminar código muerto, cerrar brechas de seguridad menores y estandarizar la experiencia de usuario. También se aplicaron optimizaciones de rendimiento en consultas frecuentes y se mejoró la accesibilidad de los formularios.
+
+- **Rama/base:** `main`
+- **Tenant de pruebas:** `tenant_refaccionaria_la_casita` (`tenant_id = 33`)
+- **Servicio:** `nexus-pos.service` (puerto 5001)
+- **Estado final:** operativo, tests pasando
+
+---
+
+## 1. Problemas críticos corregidos
+
+| Problema | Solución | Archivos principales |
+|----------|----------|----------------------|
+| `@require_auth` sin paréntesis en `tasks_bp` | Se cambió al decorador correcto | `pos/blueprints/tasks_bp.py` |
+| Permiso inexistente `accounting.read` | Se reemplazó por `accounting.view` | `pos/blueprints/accounting_bp.py` |
+| `historical_sales.html` no cargaba `api.js` | Se incluyó el helper compartido | `pos/templates/historical_sales.html`, `pos/static/js/api.js` |
+| `featureProximamente` no estaba disponible en `customers.js` | Se expuso la función en el módulo | `pos/static/js/customers.js` |
+| `pos_engine` usaba `threading` sin importar y la caja sin `FOR UPDATE` | Se agregó `import threading` y lock pesimista de caja | `pos/services/pos_engine.py` |
+| Race condition en stock de ventas | Se agregó `SELECT ... FOR UPDATE` sobre `inventory_stock` | `pos/services/pos_engine.py` |
+
+---
+
+## 2. Problemas mayores corregidos
+
+| Problema | Solución | Archivos principales |
+|----------|----------|----------------------|
+| N+1 en `complete_layaway` | Se cargan todos los items en una sola consulta | `pos/services/pos_engine.py` |
+| Race conditions en folios CFDI y números de póliza | Se usó `pg_advisory_xact_lock(hashtext(prefix))` | `pos/services/cfdi_queue.py`, `pos/services/accounting_engine.py` |
+| N+1 en flotilla (schedules/history) | Se crearon endpoints bulk `/vehicles/schedules` y `/vehicles/history` | `pos/blueprints/fleet_bp.py`, `pos/static/js/fleet.js` |
+| N+1 en dashboard (ventas recientes) y `global_invoice` | Se consolidaron consultas | `pos/blueprints/dashboard_stats_bp.py`, `pos/services/global_invoice.py` |
+| `client_secret` de MercadoLibre expuesto en frontend | Se movió el flujo OAuth a backend con endpoint `/connect/init` | `pos/blueprints/marketplace_external_bp.py`, `pos/static/js/marketplace_external.js` |
+| Botones/filtros sin handler en config, customers y accounting | Se conectaron eventos y handlers faltantes | `pos/static/js/config.js`, `pos/static/js/customers.js`, `pos/static/js/accounting.v9.js`, `pos/templates/*.html` |
+| Botones/filtros sin handler en invoicing | Se implementaron filtros, export CSV y acciones | `pos/static/js/invoicing.js`, `pos/templates/invoicing.html` |
+
+---
+
+## 3. Mejoras de rendimiento
+
+- **Locks atómicos:** los folios de órdenes de servicio, CFDI y pólizas contables ahora se generan bajo `pg_advisory_xact_lock` para evitar duplicados bajo concurrencia.
+- **Consultas bulk:** flotilla y dashboard redujeron drásticamente el número de queries al backend.
+- **Virtual scroll:** se mantiene en tablas grandes (clientes, programas de mantenimiento, historial) para renderizado eficiente.
+- **Cache busting:** se actualizaron los query strings estáticos a `?v=32` y el Service Worker a `v32` para forzar la actualización de assets en navegadores y PWA.
+
+---
+
+## 4. Mejoras de UX y accesibilidad
+
+- **Formularios accesibles:** se agregaron `aria-label`, `id` y `<label>` explícitos en:
+  - POS: pago mixto, toggle de costo/margen, campos de vehículo del modal de cliente.
+  - Clientes: búsqueda y filtros.
+  - Catálogo: búsqueda y filtro de niveles.
+  - Facturación: búsquedas de facturas, notas de crédito y complementos de pago.
+- **Estados de carga consistentes:** se añadió `renderLoadingState()` en `pos-utils.js` con estilo en `pos-ui.css`, y se aplicó en:
+  - Clientes (`customers.js`)
+  - Facturación (`invoicing.js`)
+  - Flotilla (`fleet.js`): vehículos, programas, historial y alertas.
+- **Empty states normalizados:** los errores y listas vacías ahora usan `renderEmptyState()` en lugar de mensajes inline inconsistentes.
+
+---
+
+## 5. Limpieza de código
+
+- Se eliminaron las versiones obsoletas `pos/static/js/accounting.js` y `pos/static/js/accounting.min.js`.
+- Se consolidó la lógica contable en `pos/static/js/accounting.v9.js`.
+- Se removieron `console.log`/`console.error` de depuración de `accounting.v9.js`.
+- Se limpió encabezado comentado de `accounting.v9.js`.
+
+---
+
+## 6. Archivos añadidos
+
+```text
+pos/migrations/v4.10_fleet_permissions.sql
+pos/migrations/v4.7_workshop_business.sql
+pos/migrations/v4.8_workshop_permissions.sql
+pos/migrations/v4.9_workshop_customers_view.sql
+pos/static/js/accounting.v9.js
+pos/static/js/api.js
+scripts/allocate_existing_customer_payments.py
+```
+
+---
+
+## 7. Estadísticas del cambio
+
+```text
+54 archivos modificados
++2485 / -1300 líneas aproximadas
+```
+
+---
+
+## 8. Validación
+
+```bash
+# Sintaxis de JavaScript
+node --check pos/static/js/pos-utils.js
+node --check pos/static/js/customers.js
+node --check pos/static/js/invoicing.js
+node --check pos/static/js/fleet.js
+node --check pos/static/js/accounting.v9.js
+node --check pos/static/js/pos.js
+node --check pos/static/js/catalog.js
+
+# Tests de backend
+python3 -m pytest pos/tests/test_service_order_integration.py \
+                  pos/tests/test_bulk_import.py \
+                  pos/tests/test_facturapi_service.py -q
+# Resultado: 35 passed
+```
+
+Servicio `nexus-pos.service` verificado como **activo**.
+
+---
+
+## 9. Instrucciones de despliegue
+
+1. Aplicar migraciones SQL nuevas según el orden numérico:
+   - `v4.7_workshop_business.sql`
+   - `v4.8_workshop_permissions.sql`
+   - `v4.9_workshop_customers_view.sql`
+   - `v4.10_fleet_permissions.sql`
+2. Reiniciar el servicio para cargar cambios de backend:
+   ```bash
+   sudo systemctl restart nexus-pos.service
+   ```
+3. Refrescar la PWA en los navegadores/clientes para que `sw.js` actualice el cache a `v32`.
+
+---
+
+## 10. Notas para el equipo
+
+- Los permisos de flotilla (`fleet.view/create/edit/delete`) ya están sembrados para `owner`/`admin` y `view` para `accountant`/`workshop`.
+- El Service Worker se sirve correctamente en `/pos/sw.js` desde `static/pwa/sw.js`.
+- El helper global `api()` fue creado para páginas standalone como `historical_sales.html`.
+- No se realizaron mutaciones de git no solicitadas; el push a Gitea se hace como parte de esta entrega.
