+# 故障管理 BI 设计验收
+
+final result: passed
+
+## 最新调整：总览视觉与多维分析对齐
+
+管理总览复用多维分析的页面色板与标题布局，统一浅蓝背景、白色7px圆角面板、蓝色标题标记、细边框按钮、日期控件和表格。趋势图已闭环/未闭环使用与分布分析一致的蓝/橙色；周报新增/解决仍用蓝/绿语义色。统计和排列顺序不变。
+
+- 桌面：`../outputs/fault-overview-theme-20261013/desktop.jpg`（1448×1086）；手机：`../outputs/fault-overview-theme-20261013/mobile.jpg`（390×844），均已目视检查。
+- 两页背景均为 rgb(248,251,255)，共用主蓝、文字及边框变量；手机四卡132px等高，scrollWidth=390，无横向溢出。
+- 页签往返、手机日期选择打开/关闭正常，趋势和周报导出入口保留。类型检查、生产构建和diff检查通过；本次验证控制台无新增error/warn。
+- 未改动数据接口或统计口径；未重复执行数据库测试与下载导出文件。
+
+## 最新调整：管理总览与处理效率合并
+
+按用户最新要求，管理总览恢复原来的页面及 `/overview` 统计，依次展示实时汇总、故障处理趋势、故障运维周报；移除独立处理效率页签，保留多维分析、故障明细。以下原参考设计验收为历史记录，管理总览以本段及最新截图为准。
+
+- 桌面证据：`../outputs/fault-overview-merged-20261013/desktop.jpg`，1448×1086。
+- 手机证据：`../outputs/fault-overview-merged-20261013/mobile.jpg`，390×844；四卡均为132px，无页面横向溢出。
+- 验证原今日新增、本日解决、当前在办及累计台账，当前在办下钻27单；页签往返正常，三个统计区同页出现，周报恢复默认业务周。
+- TypeScript、生产构建、diff检查通过；本次未修改后端统计口径。页面非空、无框架覆盖层，最终验证期间控制台无新增error/warn。
+- 保留趋势与周报的独立日期、下钻和导出按钮；本次未重复下载导出文件。已清除临时viewport覆盖。
+
+## 对照依据
+
+- 来源：`/var/folders/3b/z3fk0dm9419dk7qffdvrwmfh0000gn/T/codex-clipboard-1efea2c0-2930-4600-b725-874c3c2a1f4f.png`
+- 实现：`http://127.0.0.1:4310/asset#faults`
+- 桌面截图：`../outputs/fault-dashboard-20261013/desktop.jpg`
+- 同图左右对照：`../outputs/fault-dashboard-20261013/comparison.jpg`（左参考，右实现）
+- 局部对照：`../outputs/fault-dashboard-20261013/comparison-filters-kpis.jpg`（筛选、指标、提示条）
+- 参考和实现各 1448×1086 像素；CSS viewport 1448×1086，DPR 1，无密度缩放。比较图片由两份截图并排组成，展示工具可能缩小，局部图另行检查。
+- 状态：浅色、管理总览、2026-09-14 至 2026-10-13、全部授权数据。参考使用示例数据，实现使用实际数据库；数值、分类数量和客户名称不要求与示例相同。
+- 手机：390×844 `mobile.jpg`；320×844 `mobile-320.jpg`。另有 `efficiency.jpg`、`drilldown.jpg`。
+
+## Findings / 比较与修复历史
+
+1. [P2，已修复] 现有应用顶部浮动面包屑与新标题重叠。通过仅作用于故障页面的 shell 选择器隐藏重复面包屑；最终桌面、手机截图无重叠。
+2. [P2，已修复] 第一版分析面板和列表过长，重点跟进过度后移。车型默认前三、客户默认前四、跟进默认前三，提供全部入口；减小图表行距、等级间距和桌面表格单元格内边距。最终 `comparison.jpg` 显示完整指标、分析面板及跟进入口。
+3. [P2，已修复] 分布图自动跳过部分区域标签。YAxis interval=0；补充柱尾数量，包括未闭环为零的组，保留精确数量表与下钻。
+4. [P2，已修复] 320px 下标题和导出挤占，原生筛选框太窄。标题操作区换行，筛选单列，指标标题字号适配。`mobile-320.jpg` 显示全部入口及所选值，没有横向页面溢出。
+5. 最终对照无未解决的 P0/P1/P2。以下为有意保留的业务差异，而非像素复刻：现有导航品牌与功能、页面水印、今日新增/本日解决/累计台账、未标注等级及部位、真实长车型名称和运维处置人第二列。实际内容略长，重点跟进明细需继续向下滚动；避免通过隐藏未知数据或缩小明细字体模拟示例高度。
+
+## 必查表面
+
+- 字体：沿用应用中文无衬线回退，桌面标题 24px、面板标题 14px、指标 29px，层级与参考一致；重点检查筛选、数字与窄屏换行。没有以图片模拟文字。
+- 间距：四指标等高、两行双列分析面板、统一边框与圆角；手机两列指标、分析面板单列，宽表内部横滚。
+- 颜色：浅蓝页面、白底面板、蓝色主操作；橙色未闭环、红色逾期，未知等级灰色。等级与实际停运含义分开说明。
+- 图像与图标：参考主要为数据图表。使用现有 Lucide 图标及真实数据图表；沿用产品已有品牌导航，未自行绘制替代参考 ONE OS 标识。无新增位图资产或虚构装饰图。
+- 文案与数据：使用真实口径和实际分类；“当前在办=待处理+处理中”，逾期为在办子集；“处置记录”避免把 solve_process 当作当前工作流阶段。发生频率缺分母，停运与修复时长缺数据，明确显示待补。
+
+## 功能与数据验收
+
+- 新增 3 项后端测试；故障模块与报表导出测试合计 32 项全部通过。
+- TypeScript 检查、生产构建、git diff --check 通过。
+- 实库只读核对 63 个分组、48 个车型×部位单元格，汇总与下钻一致；在办 26=17+9，逾期5，本期106，车辆去重89。
+- 浏览器验证：华东筛选后总览39单，趋势39单，周报新增39/解决125；按月切换及报表下载；等级20单下钻、交叉单元格3单下钻、单条故障明细、十二维分析默认运维处置人/故障工单状态。
+- 手机更多筛选 L1-特急得到本期1单；其他区域空数据正确显示0和空态。320/390px 页面 scrollWidth 等于 viewport width。
+- 总览 Excel 下载成功，重新读取工作簿确认6张表、日期/筛选说明、冻结表头和数字106/26与页面一致。
+- 处理效率保留既有柱图、周报折线图、今日行提示、报表导出与下钻。
+- 最终验证时间段（08:40 UTC 后）无浏览器 error/warn；开发编辑过程曾有一次已修复的 HMR 导入错误，未计为运行期问题。
+- 浏览器测试后恢复管理总览、全部筛选，并清除临时 viewport override。
+
+## Open Questions / 残余限制
+
+- 故障发生频率需要同期服务车辆规模；实际停运、修复时长需要业务定义和数据来源，未捏造这些指标。
+- 未进行不同浏览器引擎实机测试；已验证当前 in-app 浏览器桌面和移动断点。
+- 只读接入，未修改业务数据库；本次改动未提交或推送。
+
+## Implementation Checklist
+
+- [x] 参考布局落地并绑定真实数据。
+- [x] 汇总、业务筛选、分布、矩阵、客户和重点跟进下钻。
+- [x] 趋势/周报继承筛选并保留导出。
+- [x] 数据权限、空数据、移动端与导出验证。
+- [x] 同图对照、局部检查、问题修复和最终证据保存。
+
+## Follow-up Polish
+
+- P3：后续如提供统一品牌资产，可单独统一应用级导航标识；当前保持现有产品导航。

 - 周报：日期、星期、新增故障、解决故障，按日期倒序；不导出接收处理指标。
 - XLSX 包含带标题、范围、数据时间、汇总指标的统计表；当前有图表时附加「图表」工作表，以图片保存页面图表快照并保持比例。图表为静态快照，修改统计表不会联动图表。

+
+## 风险与服务分析总览（2026-10-13）
+
+故障管理按最新确认保留「管理总览 / 多维分析 / 故障明细」三个页签。管理总览与处理效率合并，恢复原有页面及统计：今日新增、本日解决、当前在办（待处理 + 处理中，逾期为子集）、累计台账，沿用 `/overview` 接口；下方直接展示原有故障处理趋势与故障运维周报。趋势默认近30天，周报默认周六至周五，分别选择日期、导出和下钻。管理总览不受其他页签的业务筛选影响。多维分析、故障明细保留新增分析能力及统一日期、区域、客户、品牌车型查询；更多筛选包含城市、业务部门、运维处置人、故障程度、故障部位、库存状态，点击查询生效。
+
+- 期间新增故障：所选提报日期内的有效故障。对比上期采用紧邻本期、天数相同的区间；上期为零时显示无可比基数。
+- 受影响车辆：同批故障按关联车辆 ID 去重，缺 ID 时使用故障车牌；两者都缺失的不计车辆数，单列数据完整性提示。车辆跨组可能重复，不直接累加。
+- 当前在办：已应用业务筛选下，所有日期的待处理 + 处理中。逾期为其子集；最长逾期按截止时间到数据时间的天数向上取整。
+- 区域、等级、客户、车型分布和车型×部位矩阵：按本期提报队列统计，闭环状态截至更新时间。一单多部位分别计入单元格，车型合计按单去重。
+- 客户影响表：本期影响车辆去重；同一客户的当前在办不限提报日期。库存空客户单列库存车。仅展示本期存在故障的客户组。
+- 重点跟进：当前在办中优先展示逾期，同优先级按提报时间倒序。完整明细可切换本期、在办、逾期及累计台账，搜索车牌、单号、描述或运维处置人。
+
+新增只读字段：`fault_level`、`fault_categories`、`solve_process`。等级映射经 OneOS 字典核对：1=L1-特急、2=L2-紧急、3=L3-一般、4=L4-提示；缺失等级/部位独立显示未标注。处置记录使用 `solve_process`，不将 AI 流转字段 `process_status` 当作业务处理进度。没有同期服务车辆规模、实际停运和修复时长依据，发生频率禁用并提示缺少分母，停运和修复时长提示待补数据。
+
+新增接口：
+- `GET /api/asset-faults/dashboard?start=YYYY-MM-DD&end=YYYY-MM-DD`：授权范围内汇总、筛选项、分布、交叉矩阵、重点跟进和完整性信息。
+- `GET /api/asset-faults/dashboard-analysis`：同样日期和业务筛选；`scope=cohort|open|waiting|processing|overdue|ledger|reported|closed`。cohort 为提报日期队列，reported/closed 为北京时间今日，其他为全部日期当前状态；可附 `id` 查看单条记录。
+- 趋势、周报及其下钻接口同时支持上述业务筛选。所有接口先执行权限筛选，筛选项也仅来自授权记录，保持 no-store，不写业务数据库。
+
+总览导出新增 6 张 Excel 工作表：管理总览、区域分布、故障程度、客户影响、车型分布、车型与部位。导出已加载统计快照，包含日期、业务筛选、数据时间、冻结表头、交替底色和数字格式。趋势、周报的既有导出保留，并增加业务筛选说明。
