   - ➕ "Añadir al ticket actual" — mergeRecoveredItems()
   - "Cancelar" — cierra diálogo sin acción
 
+## Bug corregido
+Los botones del diálogo no funcionaban porque `recoverSale()` seteaba `recoveringSaleId` al abrir el diálogo, lo que habilitaba `disabled={recoveringSaleId !== null}` en los botones del diálogo.
+- **Fix**: ya no se setea `recoveringSaleId` al abrir el diálogo (solo se setea durante la carga real)
+- **Fix**: los handlers de los botones ahora usan `.catch()` para mostrar errores
+
 ## Verificación
 - [x] TypeScript compila sin errores
 - [x] Polling 10s eliminado del panel de ventas pendientes
 - [x] Diálogo de merge visible al recuperar con cart items
 - [x] Tres opciones funcionando correctamente
+- [x] Botones no deshabilitados al abrir diálogo
