+# POS-FIX-9: Implementer Evidence
+
+## Problema
+1. El panel de ventas pendientes hacía polling cada 10 segundos causando flicker constante.
+2. Al recuperar un ticket con artículos en el cashier, se hacía merge automático sin preguntar.
+
+## Cambios realizados
+
+### Frontend
+**`project/apps/pos/src/app/(terminal)/page.tsx`**
+- **Eliminado polling de 10s** — solo refresh manual via botón
+- **Nueva función `doRecoverSale(sale)`** — recuperación real (reutilizada por parkAndRecover y merge)
+- **Nueva función `parkAndRecover()`** — aparca ticket actual y recupera venta seleccionada
+- **Nueva función `mergeRecoveredItems()`** — añade items recuperados al ticket actual
+- **Modificada `recoverSale(sale)`** — si cart tiene items, abre merge dialog en vez de auto-merge
+- **Nuevo estado `mergePendingSale`** — almacena la venta a recuperar para el diálogo
+- **Diálogo de merge** con 3 opciones:
+  - 💾 "Dejar actual pendiente y recuperar" — parkAndRecover()
+  - ➕ "Añadir al ticket actual" — mergeRecoveredItems()
+  - "Cancelar" — cierra diálogo sin acción
+
+## 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
