 ## Fidelity Ledger
 
 | Surface | Required fidelity | Implementation evidence | Result |
 | --- | --- | --- | --- |
-| Monitoring workflow | 搜索、筛选、地图/列表切换、分页和实时刷新周期不能被视觉重构改变。 | 保留原查询、路由和轮询实现，只重组列表渲染与响应式样式。 | Preserved. |
-| Fleet hierarchy | 车辆总数、当前在线、行驶和告警必须优先；今日上报与无实时位置属于辅助证据。 | 手机端主指标采用清晰的 `2 × 2` 网格；辅助指标独立放在底部并压缩大数。 | Improved. |
-| Vehicle evidence | 车牌、VIN、速度、当日里程、总里程、协议和位置必须在一眼可扫范围内。 | 手机卡片固定为身份、三项核心证据、位置三层；桌面继续使用连续 Semi Table。 | Improved. |
-| Mobile density | 单屏车辆数需要显著增加，但不牺牲字段可辨认性。 | 卡片高度从约 `147px` 降至 `109px`；列表视口可容纳约 `4.05` 张卡片，截图中从约 `2.5` 辆提升到 `4` 辆。 | Improved. |
-| Realtime performance | 高频刷新不能让全部车辆卡片无差别重绘。 | 移动卡片使用字段级 `memo` 比较；不可见卡片继续使用 `content-visibility` 和固有尺寸占位。 | Improved. |
-| Address cost | 地理位置不得随列表刷新自动消耗逆地理编码 API。 | 经纬度始终可见；地址仍由用户点击“解析位置”后按需请求。 | Preserved. |
-| Asset fidelity | 品牌和图标不得用临时图形替代。 | 沿用生产 Logo、Semi Icon、Card、Button、Table、Tag 与 Pagination。 | Preserved. |
+| Vehicle identity | 车牌、在线状态、VIN、品牌车型和三类协议来源必须完整。 | 保留原任务栏结构；车型允许两行且提供完整 `title`，协议标签保持 Semi Tag 色彩语义。 | Improved. |
+| Live evidence | 速度、SOC、总里程和当日里程不能被截断或隐藏。 | 修正移动端带上下文指标轨道的网格优先级；四项指标获得完整宽度，实测全部 `clipped=false`。 | Fixed. |
+| First viewport | 首屏必须尽快进入地图，不能被重复卡片和过高操作区占满。 | 身份、动作、位置、来源入口和章节导航收敛；地图顶部由 `652px` 提前至 `569px`。 | Improved. |
+| Location workflow | 当前坐标、按需地址解析和车辆实时跟随必须保留。 | 坐标与解析按钮合并成一行；未增加自动逆地理编码，地图和实时轮询逻辑未改。 | Preserved. |
+| Source evidence | 总里程、当日里程和“查看全部来源”仍需打开同一证据面板。 | 实测总里程按钮打开 Semi Bottom SideSheet，日期和来源证据可见，关闭后恢复页面。 | Passed. |
+| Section navigation | 实时位置、最近事件、实时遥测和车辆主档必须可达。 | 四个 Semi Button 保留可访问名称；点击实时位置后目标区域获得焦点。 | Passed. |
+| Desktop stability | 移动端收敛不能造成桌面布局回退。 | `1440 × 900` 桌面截图保持原信息结构，横向溢出 `0px`。 | Preserved. |
+| Asset fidelity | 品牌、地图和图标不得由临时资产代替。 | 继续使用生产 Logo、高德地图、Semi Icon、Card、Button、Tag 与 SideSheet。 | Preserved. |
 
 ## Interaction And Accessibility Checks
 
-- 手机端“筛选”可展开并可通过“收起”恢复列表；
-- 地图/列表使用原有可访问 tab 语义，车辆卡片具有“车牌 + 实时数据”标签；
-- “地图”和“解析位置”按钮均保留车辆级可访问名称；
-- `390px` 视口文档横向溢出为 `0px`，主指标和辅助指标无裁切；
-- 移动卡片实测高度 `109px`，第一页仍渲染 `50` 辆并由内部列表滚动；
-- 控制台未发现本次改动产生的运行时异常；仅保留 Semi UI 在 React StrictMode 下既有的 `findDOMNode` 弃用警告。
+- 页面根节点保留“车牌 + 车辆档案”的可访问标签；
+- 总里程和当日里程继续以有名称的按钮进入来源证据；
+- 来源证据 SideSheet 可打开、读取并通过“关闭来源证据”退出；
+- 章节导航点击后执行平滑滚动并将焦点交给目标区域；
+- `390px` 与 `1440px` 视口横向溢出均为 `0px`；
+- 生产数据下总里程、当日里程、速度和 SOC 均无视觉裁切；
+- 控制台未发现本次改动产生的运行时异常。
 
 ## Comparison History
 
 ### Pass 1 — fixed
 
-- 生产手机端的“今日上报”和“无实时位置”数值被截断，信息层级与主要车队指标混在一起。
-- 生产车辆卡片纵向留白过多，`390 × 844` 首屏只能看到约 `2.5` 辆。
-- 已将辅助指标改成完整的紧凑数值，将每辆车的协议、里程与坐标收拢到固定证据网格。
-- 并排对比后未发现 P0、P1 或 P2 视觉与交互问题。
+- 原移动端指标轨道仍被通用 `has-context` 网格分成两列，隐藏的来源上下文占用一半宽度，导致总里程显示为 `80,27…`。
+- 当前修复将四项实时指标恢复到完整宽度的 `2 × 2` 网格，并压缩重复的纵向间距。
+- 同视口并排对比确认地图在首屏获得约 `83px` 的额外可见空间，车型和里程信息完整。
+- 未发现 P0、P1 或 P2 视觉与交互问题。
