+- `Cart`: pertenece a un tenant y opcionalmente a un usuario; calcula el total, permite agregar, actualizar o quitar ítems y apunta a su reserva de stock vigente mediante `current_stock_reservation_id`.
 - `CartItem`: referencia un `CatalogItem` y, opcionalmente, una `Variant`; sólo persiste la selección y cantidad, y expone siempre los datos vigentes del catálogo.
 
 ## Servicios
 
 - `CartService`: obtiene el carrito, modifica ítems y administra la cookie del token invitado.
-- `ExpireCartReservationsService`: libera las reservas vencidas de carritos activos y elimina los carritos que quedan vacíos.

 Un carrito puede pasar a `checkout`. Las compras directas usan un carrito técnico con `origin=direct_checkout`; los carritos normales conservan `origin=user` y pueden restaurarse al cancelar o vencer la compra.
 
-El comando unificado `php artisan reservations:expire` procesa primero las compras vencidas y luego las reservas activas sin compra cuyo `expires_at` haya vencido. Se ejecuta cada minuto mediante el scheduler, conserva la fila de reserva con estado `expired`, elimina el ítem abandonado y elimina lógicamente el carrito cuando queda vacío. Cada intento registra sus resultados o su error en el log diario `storage/logs/commands/commands-AAAA-MM-DD.log`.
+Cada edición sincroniza una única reserva para el carrito completo. Si varios ítems o bundles consumen el mismo inventario, se persiste una sola línea con la cantidad agregada. Al editar durante checkout, la compra anterior queda `superseded`, se desvincula y el carrito conserva la misma reserva activa con sus líneas actualizadas.
+
+El comando unificado `php artisan reservations:expire` recorre una sola vez las reservas activas cuyo `expires_at` haya vencido. Cuando pertenecen a un carrito, conserva la reserva y sus líneas como historial, libera el stock como conjunto y cambia el carrito asociado a `expired` sin eliminar sus ítems. Al volver a resolver ese carrito desde la API, el anterior pasa automáticamente a `abandoned` y se crea uno activo y vacío para la misma identidad. El cliente nunca necesita reiniciarlo explícitamente. La API también materializa este vencimiento al acceder al carrito aunque el comando programado todavía no haya corrido.
