 Depende de `Catalog` para productos y variantes, de `Tenant` para aislar datos y de `Auth` cuando existe usuario. Toda operación debe comprobar que carrito e ítem pertenecen al tenant actual.
+
+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`.

+## 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.
+
 ## Dependencias y reglas
 
 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.

 ## Propósito
 
-Implementa el ciclo de compra y checkout: crea una compra desde el carrito, toma una instantánea de sus ítems, reserva inventario, permite ediciones, inicia el pago y confirma, cancela o vence la operación.
+Implementa el ciclo de compra y checkout: crea la cabecera de compra desde un carrito, mantiene sus líneas vivas contra catálogo durante el checkout, inicia el pago y materializa el snapshot definitivo al confirmar, o cancela y vence la operación.
 
 ## Modelo
 
 - `Purchase`: raíz de la compra; estados `created`, `pending_payment`, `paid`, `cancelled`, `rejected` y `expired`.
-- `PurchaseItem`: snapshot del producto o variante, cantidad, precio y total al comprar.
+- `PurchaseItem`: snapshot definitivo del producto o variante, creado recién al confirmar la compra.
 - `TelepagosQr` y `TelepagosPayment`: datos del QR e intentos/resultados del proveedor.
 - `PurchasePaid`: evento emitido una sola vez al pasar a pagada bajo bloqueo transaccional.

 `CheckoutService` es la fachada estable. Delega en:
 
-- `StartCheckoutService`: inicia la compra desde el carrito.
+- `StartCheckoutService`: inicia la compra desde el carrito o crea un carrito técnico para compra directa, sin crear todavía `PurchaseItem`.
-- `EditCheckoutService`: modifica cliente o cantidades antes del cierre.
+- `EditCheckoutService`: modifica los datos del comprador antes del cierre.
-- `CompleteCheckoutService`: completa, envía a revisión o confirma el pago.
+- `CompleteCheckoutService`: completa, envía a revisión o materializa los `PurchaseItem` al confirmar el pago.
 - `ReleaseCheckoutService`: cancela, vence y procesa vencimientos pendientes.
-- `SourceCartService`: sincroniza, restaura o finaliza el carrito fuente.
+- `SourceCartService`: sincroniza o finaliza el carrito de checkout asociado a la compra.
 - `CatalogSelectionResolver` y `PurchaseItemSnapshotFactory`: resuelven selecciones y generan snapshots.
 
+Durante `created` y `pending_payment`, `PurchaseResource` publica las líneas del carrito con `items_source=cart`; una compra materializada publica `items_source=purchase`. Los datos descriptivos y económicos del checkout se resuelven siempre desde el catálogo vigente.
+
+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.
+
 `UserPurchaseLimitService` controla límites de compra y `CheckoutService` conserva el punto de entrada para controladores e integraciones.
