+# VERTICAL SLICE - NOT FOR PRODUCTION
+# 轮间结算节奏化断言批（迭代 8 卡⑦ AC⑤/T9——逻辑先行断言面）：
+# ① 演出队列排空前后核心逻辑状态逐位一致（演出关停不产生分叉——排播队列零核心触碰的结构证明）；
+# ② 零丢行：step_row 信号总数 = 明细带实收行数（排播/排空两路都不吞行）；
+# ③ 段间延迟取数面双态（常态 >0 / 减动效 =0 归零不跳过——pace_delay_for 直读）。
+# 载体：main.tscn 实例（同 ui_click_probe 形态——组合根全链在座），真实冒险驱动至首战结算后断言。
+# 运行：godot --headless --path game --script res://tests/unit/presentation/pacing_queue_test.gd（expect 0）
