+## 2026-07-28 (傍晚) — 光耦参与模式下 LEDA 同步继电器状态
+
+光耦参与模式 (MODE 2-6) 下，绿色 LED 原先跟随线圈 `FLAG_IN`/`FLAG_OUT` 变化，
+在雷达单独触发（如人车混行防砸窗口）时 LED 不亮。修正为：
+
+- TMR1 ISR 50ms 块末尾，`g_output_radar_mode >= 2` 且正常运行（非断开/非稳定期）时，
+  LEDA 直接跟随 `g_loop_acs_info.relay1_state`
+- 断开/稳定期 200ms 闪烁优先级不变（5ms 段优先处理）
+
+> 效果：继电器吸合→绿灯亮，继电器释放→绿灯灭，与线圈或雷达触发源无关。
