+"""Regression tests for KIN-126 — фильтр по дате выполнения задач.
+
+Проверяет backend-поведение:
+1. Колонка completed_at добавляется в таблицу tasks при инициализации БД
+2. Новая задача имеет completed_at=None по умолчанию
+3. update_task(status='done') устанавливает completed_at как ISO-строку
+4. update_task(status='done') — completed_at является валидной ISO-строкой
+5. update_task(status='in_progress') не устанавливает completed_at
+6. update_task(status='cancelled') не устанавливает completed_at
+7. Обновление полей без смены статуса на done не трогает completed_at
+8. update_task(status='blocked') не устанавливает completed_at
