按钮与面板: - 「系数」按钮改名为「系数/偏移」;点击展开的二级面板在原「系数调整」输入框下方新增「偏移调整」: 与「系数调整」同一套绘制(标题 + 标题栏右侧的还原图标),下面两行分别是「Y轴」「时间轴」, 每行左侧说明文字、右侧内联输入框(整行数值框)。 - 「Y轴」默认 0.00,非编辑态**始终带正负号**(+0.00 / -12.50),小数不足两位时补两位、更高精度保留更多位。 - 「时间轴」默认 0.00,非编辑态显示与双光标差值同一套复合单位文本(`Δt:500ms`、`Δt:1h 1min 2s`); 进入编辑态时显示以**秒**为单位的数值,并在输入框最右侧提示单位 `s`。 - 「偏移调整」的还原图标把两个偏移恢复为默认值 0;「系数调整」的还原图标仍只重置系数。 - 面板/输入框的编辑初值与显示文本分离(`MenuItem::editValue` / `editSuffix`), 非编辑态(`Δt:…`)与编辑态(`3662`)不一致时也能正确回显。 语义与结算顺序: - 结算顺序变为 **系数 → 绝对值 → 镜像 → 偏移**(前三步不变)。 - Y 偏移:给绘制值加常数(波形上下移动);时间偏移:采样绘制在 `t + offsetTime` 处 (例如 t=1s、偏移 -0.5s → 画在 0.5s)。 - ⚠️ Y 偏移以**未镜像空间**为准:垂直镜像开关变化时同步取反偏移量, 使绘制等价于「先加上偏移再镜像」(开关来回切换可逆)。 - 绘制链路全部跟随偏移:`BuildPolyline`(逐点描边 / 像素列包络 / 跨列边界插值 / 粗粒度分组层, 保序的 Y 偏移直接加在分组极值上)、派生预览曲线、光标取值读数(含 Δt)、 可见区间 Y 轴自适应、整段自适应的区间映射;折线缓存键、场景指纹、样式快照与图层指纹都纳入两个偏移。 派生信号(实验性功能「构建为新信号」): - 修复「预览是调整后的波形、构建出来却按原始状态绘制」:新信号**继承源信号的调整变换** (系数/绝对值/两个镜像/两个偏移)——网格预览绘制的是 `变换(滤波结果)`, 而构建出的信号只存了滤波结果,因此必须把变换一并继承; 时间轴偏移**只能**靠继承(派生信号与源信号共用同一文件时间轴,无法把时间平移烘进数据)。 离屏验证(不干扰用户): - ⚠️ harness 现在在每次注入鼠标消息后**立即释放本窗口的鼠标捕获** (宿主 WM_LBUTTONDOWN 会 SetCapture,隐藏窗口同样会把用户的真实鼠标输入吸走); 后续消息本来就是直接投递,无需捕获。 - 新增 [AP]:按钮标签不裁切、面板 5 行顺序与「偏移调整」位于系数输入框下方、 Y轴/时间轴行的标签与输入框同行且默认值/单位提示正确、时间轴编辑态显示秒值并在最右侧提示 `s`、 Y 偏移提交/显示正负号/波形整体平移量、时间偏移提交/Δt 复合单位(含 3662 → Δt:1h 1min 2s)/ 编辑态为秒、**按"偏移若干个采样点"构造的精确几何验证**(采样被画到移位后的像素位置、且不再画在原处)、 读数跟随、两个还原图标、垂直镜像对 Y 偏移取反(可逆)、 以及派生信号继承变换;[AL] 补充「系数→绝对值→镜像→偏移」的顺序与区间映射(含 Y 偏移)。 - 合计 645/645 通过;make clean && make all 零警告。
