 # Проверки поэтапного переноса из Owniverse.U
 
+## Иконки стадий жизни
+
+`godot --headless --path Owniverse.GI --script res://tests/test_life_icons.gd`
+
+Проверяются одновременная разблокировка подробных и общих иконок EON/LP и C0.0/C0, количества свободных и связанных планет без двойного учёта, переключение подпанелей и очистка счётчика при исчезновении стадии. Сохранение игрока не используется.
