+- `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 Al editar durante checkout, la compra anterior queda `superseded`, se desvincula y el carrito conserva la misma reserva activa con sus líneas actualizadas.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.

 - `BaseIntegrationService`: resuelve el cliente desde el tenant operativo y carga exclusivamente la configuración del cliente.
 - `MailService`: envío de correo usando la integración configurada.
 - `TelepagosIntegrationService`: autenticación, caché de token, generación de QR y consulta de cobros.
- `TelepagosWebhookService`: procesa notificaciones recibidas desde Telepagos.

 ## Endpoints

- CRUD global bajo `/integrations`.
 - Consulta y configuración por cliente bajo `/clients/{client}/integrations`.
- `POST /webhooks/telepagos/{client}` para notificaciones del proveedor.

 ## Logging de Telepagos

-Los eventos de autenticación, QR, consultas de cuenta y procesamiento de webhooks se escriben en el canal diario `telepagos`, separado del log general. Los archivos se generan en `storage/logs/telepagos/telepagos-YYYY-MM-DD.log`; el nivel y la retención se configuran con `TELEPAGOS_LOG_LEVEL` y `TELEPAGOS_LOG_DAYS`. Tokens y credenciales se eliminan del contexto antes de registrar respuestas del proveedor.

-Se integra con `Client`, `Tenant` y con el checkout de `Purchase`. `Notification` utiliza `MailService`. El tenant conserva el contexto operativo y de branding, pero nunca es dueño de credenciales. Las credenciales no se exponen en respuestas ni logs; los webhooks deben validar su contrato antes de alterar una compra.

-# Dominio MailTest
-
-## Propósito
-
-Ofrece una operación técnica para verificar la configuración de correo de un tenant sin ejecutar un flujo funcional real.
-
-## Componentes
-
- `MailTestController`: endpoint invocable de envío.
- `SendTestMailRequest`: valida destinatario y contenido requerido.
- `MailTestService`: coordina el envío de prueba.
- `TestMail`: mailable utilizado para construir el mensaje.
-
-## Endpoint
-
- `POST /{tenant_code}/mail-test/send`.
-
-## Dependencias
-
-Usa la configuración de correo del dominio `Integration` y resuelve el tenant indicado.
-
-## Consideraciones
-
-Es una herramienta de diagnóstico. Debe restringirse o deshabilitarse en entornos donde no corresponda exponer envíos de prueba, y nunca debe registrar credenciales.

 - `TenantMenu`: configuración específica por tenant, incluyendo contenido estático cuando corresponde.
 - `MenuRole`: asociación entre menú y rol autorizado.

-## Servicios
-
-`TenantMenuService::configure()` crea o actualiza atómicamente la configuración de un menú para un tenant. Solo conserva `static_content` cuando el menú fue definido como contenido estático.
-
-## Endpoints
-
- Recurso REST `/menues` mediante `MenuController`.
- `POST /{tenant_code}/menues/{menu_code}` para configurar un menú del tenant.
-
 ## Dependencias y reglas

-Depende de `Tenant` y `Authorization`. Los códigos de menú y tenant forman la identidad lógica de la configuración; el contenido enviado debe respetar el tipo definido por `Menu`.
+Depende de `Tenant` y `Authorization`. Los menús se configuran mediante seeders y relaciones internas; no se exponen endpoints públicos de administración.

 `CheckoutService` es la fachada estable. Delega en:

- `StartCheckoutService`: inicia la compra desde el carrito o crea un carrito técnico para compra directa, sin crear todavía `PurchaseItem`.
+- `StartCheckoutService`: inicia la compra desde el carrito o crea un carrito técnico para compra directa, refresca el vencimiento de la reserva agregada y crea los snapshots `PurchaseItem`.
 - `EditCheckoutService`: modifica los datos del comprador antes del cierre.
 - `CompleteCheckoutService`: completa, envía a revisión o materializa los `PurchaseItem` al confirmar el pago.
- `ReleaseCheckoutService`: cancela, vence y procesa vencimientos pendientes.
+- `ReleaseCheckoutService`: cancela o vence una compra y aplica sus efectos comerciales; el scanner unificado del dominio Catalog detecta las reservas pendientes de vencimiento.
 - `SourceCartService`: sincroniza o finaliza el carrito de checkout asociado a la compra.
 - `CatalogSelectionResolver` y `PurchaseItemSnapshotFactory`: resuelven selecciones y generan snapshots.

-Al informar una transferencia, la compra pasa de `pending_payment` a `in_review` y deja de vencer. Si el comprador abandona el checkout durante la revisión, la compra y sus reservas permanecen intactas y se crea un carrito activo nuevo para que pueda seguir comprando. Adminapp puede confirmar o anular explícitamente la compra en revisión.
+Al iniciar checkout o elegir un medio de pago se refresca directamente `StockReservation.expires_at`, que es la única fuente de verdad y se expone como `expires_at` en la respuesta pública de la compra. El refresco sólo se permite mientras la reserva siga vigente; una fecha vencida bloquea todas las mutaciones aun antes de que corra el scheduler. Al materializar la expiración, la compra pagable, su carrito y la reserva pasan a `expired` dentro de la misma transacción. Al cancelar o reemplazar una compra recuperable, ésta se desvincula y el carrito conserva la misma reserva activa. Al informar una transferencia, la compra pasa de `pending_payment` a `in_review` y ese vencimiento se limpia. Si el comprador abandona el checkout durante la revisión, la compra y sus reservas permanecen intactas y se crea un carrito activo nuevo para que pueda seguir comprando. Adminapp puede confirmar o anular explícitamente la compra en revisión.

-Las cantidades y variantes se editan mediante el dominio Cart. El endpoint autenticado `PATCH /checkout-carts/{cart}/items/{cartItem}` valida que el carrito pertenezca al usuario y a una compra editable. Cuando existe un cambio real, invalida atómicamente el intento de pago anterior, recalcula el total y renueva la reserva; Purchase no expone operaciones sobre líneas antes de la confirmación.

-# Dominio StorageTest
-
-## Propósito
-
-Expone operaciones técnicas para comprobar la escritura en S3 y la generación de URL temporales.
-
-## Componentes
-
- `S3TestController`: recibe solicitudes de carga y URL temporal.
- `S3TestService`: almacena un archivo de prueba y genera el enlace firmado.
- `StoreS3TestFileRequest`: valida la carga.
- `GenerateS3TemporaryUrlRequest`: valida ruta y tiempo de expiración.
-
-## Endpoints
-
-Bajo `/storage-test/s3`:
-
- `POST /upload`.
- `GET /temporary-url`.
-
-## Consideraciones
-
-Es infraestructura de diagnóstico, no una API funcional de archivos. Debe restringirse por entorno o autorización. Para adjuntos de negocio se debe usar el dominio `Attachable`.
