一、滚动过渡动画在巨型信号处卡顿 —— 真因是「退化成整幅重绘」 滚动到**从未构建过图层的区域**时，可见网格一个都贴不出图层像素 ⇒ BlitWideBuffer() 返回 false ⇒ 落到 Paint() 末尾的整幅重绘 ⇒ 把本帧全部可见网格的波形（含千万级采样的巨型信号）每帧重画一遍。 实测（MF4 124 网格 + VERY_BIG_DATA 5 网格，点选最后一个信号）：单帧 20~35ms，且「可见的巨型信号 网格数」越多越慢（0 个 ≈20ms、5 个 ≈34ms）；对照手动拖滚动条只要 ~6ms。 修法：BlitWideBuffer 只要还能画网格底衬（backing 非空）就返回 true， 只有 blits 与 backing 都为空时才交给整幅重绘 —— 这正是「没来得及画信号时就按只有网格叠底的状态继续滚动」。 实测：动画均值 23.0→11.2ms、最坏 35.6→13.1ms；含 5 个巨型信号网格的帧 33→10.7~12.3ms。 二、面板动画帧只重绘面板（额外 −2.7ms/帧） 新增 Application::m_panelDirty：滚动定时器在只有面板动画在跑时置位，Render 走 else if (panelOnly) 只重绘面板 + 分隔条（SignalPanel::Paint 会铺满自己的区域）。m_chromeDirty（真内容变化）仍走完整装饰重绘。 ⚠️ 回送仍是 if (fullFrame) {整窗} else {绘图区} 的无条件分支（遵守 §9.41）。 实测帧耗时拆解：plot 4.8ms / plot+panel 11.4ms / plot+全装饰 13.9ms。 三、分组行「N 项」计数：只折叠展开，绝不进入改名 新增 RowPart::GROUP_COUNT 与 SignalPanel::GroupStatsRect(row)（绘制与命中的唯一几何来源，命中矩形在 文本左右各外扩 3 逻辑像素）。RowHitPart 在名称区域之前判定计数区： - OnLButtonDown：折叠/展开；OnDoubleClick：只折叠/展开，任何点击频率都不进入改名； - DoubleClickIsPlainPress 返回 true ⇒ 快速连点每一击都生效。 ⚠️「快速双击进改名」的计时只对 RowPart::BODY 记录（否则“点计数、紧接着点名称”会被误判成双击）。 四、浮动面板首次出现的位置：右上角 旧默认位置 top = plotTop + 16 + laneIndex*28：上百个网格时 laneIndex 很大 ⇒ 被夹到右下角 （实测 plotH=1081 时 topMargin=964）。改为按「当前真正显示出来的面板中排在本面板之前的个数」错开 （固定遍历顺序：网格下标 → 面板种类），并把错开量夹到“面板下沿不超过绘图区 45% 高度”以内： 第一个面板错开 0 ⇒ 正好贴在上右角（实测 topMargin=24、rightMargin=24），6 个面板时最坏 topMargin=234。 ⚠️ 判定「面板是否显示」不能只看 *Panel.open —— LanePanelState::open 默认就是 true，必须同时看功能启用。 五、开关实验性功能 / 关闭面板卡顿 —— RebuildWideBuffer() 整批重建 四个 SetLane* 末尾都调 RebuildWideBuffer()（注释说是“预建宽缓冲基底”），而它同步重渲染全部网格的图层： 129 个网格（含 5 个千万级采样的巨型信号）整批重建要几百毫秒 ⇒ 点一下功能开关 / 关闭浮动面板就会卡住。 修法：新增 PlotView::EnsureLaneLayersPrefetched() —— 只有「图层数组与网格数量不符」（首次绘制 / 增删网格） 才同步整批建立；其余只 RollWideBuffer() 登记缺失/过期网格，由既有预算（每帧最多一个）逐帧补齐。 实测：几百毫秒 → ≤22ms；巨型信号网格上开关均值滤波同样 15ms 量级。 验证（全部离屏，不占用鼠标/键盘/屏幕） - 新增 .preflight/perf/lanescroll_main.cpp（lanescroll.exe）23/23：逐帧耗时 + 「可见巨型信号网格数」关联、 「N 项」计数热区与双击不进改名、面板首现位置与多面板错开、开着巨型信号的开关/关闭面板耗时。 - 既有回归：verify 49/49、panelanim 158/158、datacheck 69/69、edgecheck 46/46、errcheck 19/19、 gridanim 93/93。 - make release / make debug 零错误零警告（用 TARGET_FILE_NAME=TargetCheck/TargetCheckD 避免与运行中实例冲突）。 文档：Documents/agent_mem.md 新增 §9.44、§11.2 第 134–140 条与变更日志一行。
