+
+## Problema
+Las ventas pendientes solo tenían un botón "Cobrar resto". No había forma de:
+1. Recuperar la venta para seguir agregando artículos
+2. Eliminar la venta pendiente sin cobrarla
+
+## Cambios realizados
+
+### Backend
+**`project/src/modules/pos/api/pos.routes.ts`**
+- Nuevo endpoint `DELETE /pos/sales/:id` para eliminar ventas pendientes
+- Valida que la venta esté en estado PENDING
+- Valida que no tenga pagos registrados
+- Restaura el inventory para cada línea de producto (disponible + cantidad)
+- Registra movimiento de inventory con operación 'cancel'
+- Marca la orden como CANCELLED en la base de datos
+
+### Frontend
+**`project/apps/pos/src/types/checkout.ts`**
+- Añadido tipo `RecoveredOrderItem` para los items devueltos por `/pos/sales/:id/items`
+
+**`project/apps/pos/src/lib/api-client.ts`**
+- Añadido `deleteSale(orderId)` → DELETE `/pos/sales/:id`
+- Re-ordenado `listOrderItems` para曝光 explícito
+
+**`project/apps/pos/src/app/(terminal)/page.tsx`**
+- Nuevo estado: `deleteConfirmFor` (venta a eliminar), `recoveringSaleId` (venta siendo recuperada)
+- Nueva función `recoverSale(sale)`:
+  - Carga items via `listOrderItems`
+  - Filtra items no-free y no-returned
+  - Añade al carrito actual (merge si hay items existentes)
+  - Refresca panel de pendientes
+- Nueva función `deleteSale(sale)`:
+  - Llama `deleteSale` API
+  - Cierra diálogo de confirmación
+  - Refresca panel de pendientes
+- UI de ventas pendientes actualizada:
+  - **"Recuperar"** (verde): carga venta en ticket
+  - **"🗑"** (rojo): abre diálogo de confirmación
+- Diálogo de confirmación de eliminación con warn de que liberará stock
+
+## Verificación
+- [x] TypeScript backend compila sin errores
+- [x] TypeScript frontend compila sin errores
+- [x] Botón "Recuperar" visible en cada venta pendiente
+- [x] Botón "🗑" abre diálogo de confirmación
+- [x] Eliminación de venta pendiente restaura inventory
