+## ver. 0.327 (2026-02-27) - Masowe usuwanie w archiwum produktów
+
+- **NEW**: `ProductArchiveController::bulk_delete_permanent()` — endpoint POST `product_archive/bulk_delete_permanent/`, przyjmuje `ids[]`, usuwa każdy produkt przez `ProductRepository::delete()`, zwraca JSON `{success, deleted, errors[]}`
+- **UX**: Kolumna checkboxów w liście archiwum produktów + pasek akcji masowych z licznikiem zaznaczonych
+- **UX**: "Zaznacz wszystkie" w nagłówku tabeli (wstrzyknięty via JS), dialog potwierdzenia przed masowym usunięciem
+- **TEST**: 2 nowe testy w `ProductArchiveControllerTest` — weryfikacja istnienia i sygnatury `bulk_delete_permanent`

 ## ver. 0.326 (2026-02-27) - API: endpoint categories/list
