 每个当前故障都是 DisplayController 中的一个 active request，包含稳定 ID、priority、severity、OLED 显示数据、首次发现时间、最后变化时间和元数据。监控只提交或清除 request，同一轮采样作为一个原子批次，全部更新后只仲裁一次。DisplayController 始终只选一个最高优先级 owner；同一 ID 更新原请求而不重复入队，恢复时删除请求，同优先级新 request 排队而不抢占，owner 恢复后按 priority、first_seen、ID 重新仲裁。OLED 在主页和全部当前告警页之间轮播，告警页右上角显示 `当前页/告警总数`，新 owner 会立即抢占一次 OLED。告警页显示时 RGB 同步表达该页对象；回到主页时 RGB 保持最高优先级 active owner，全部恢复后才 OFF。历史 power flags 只进入 diagnose 和一次性 Journal 记录。
