+# 风险与数字员工看板视觉优化
+
+## 功能一句话
+
+修正分析看板中风险看板的英文指标展示，将异常排行改成图表化表达，并优化数字员工看板的卡片布局和图表填充。
+
+## 背景与问题
+
+当前分析看板已经接入风险观察和数字员工数据，但存在三个影响个人操作体验的问题：
+
+- 风险看板仍会把 `duplicate_invoice`、`rule_center`、`unknown` 等后端 key 直接展示给用户。
+- 异常排行以多列文字列表呈现，分类多、层级碎，难以快速判断哪个异常维度最突出。
+- 数字员工看板部分卡片高度没有被内容充分利用，图表固定高度偏小，视觉上留下较多空白。
+
+## 目标与非目标
+
+目标：
+
+- 风险看板可见指标全部中文化，常见风险信号、来源、状态、规则名和未知占位都不再直接显示英文 key。
+- 异常排行聚合成一张图表化总览，保留部门、员工、供应商、规则和费用类型五个维度，并展示数量与金额。
+- 数字员工看板减少无效空白，让趋势图、技能分布、模块排行和业务产出更充分占满卡片。
+- 保持企业 SaaS 风格，继续复用现有 ECharts 封装组件和直角低饱和视觉体系。
+
+非目标：
+
+- 不新增接口，不改变后端数据契约。
+- 不引入新的图表库。
+- 不重做分析看板顶部导航、财务看板、系统看板和页面路由。
+
+## 用户与场景
+
+用户：
+
+- 财务人员、风险复核人员、管理员。
+
+场景：
+
+- 用户进入风险看板，快速识别最近周期的风险来源、风险等级和主要异常维度。
+- 用户查看异常排行时，优先通过图形长度和金额标签判断高发异常。
+- 用户进入数字员工看板，查看后台任务趋势、技能类型、工作模块和产出，不需要在大面积空白里寻找信息。
+
+## 功能能力
+
+风险看板：
+
+- 对风险信号 key、风险来源 key、状态 key、英文规则名和未知值做前端中文化。
+- 异常排行从五列小列表改为组合图表：
+  - 每个维度取排名第一项作为主条形图。
+  - 展示维度名称、异常项名称、数量和金额。
+  - 保留各维度的次级排行，作为图表下方的紧凑明细。
+
+数字员工看板：
+
+- 主趋势卡片与每日摘要组成同一行，趋势图高度随卡片拉伸。
+- 技能分布、工作模块排行和业务产出统一为等高卡片。
+- 最近工作记录独占整行，减少右侧空白和表格压缩。
+
+## 前端方案
+
+- `RiskObservationDashboard.vue`
+  - 扩展 `formatSignal`、`formatDimensionName`、`formatRiskLevel` 等映射。
+  - 新增异常排行图表数据 `rankingChartItems`，复用 `BarChart` 展示五个维度的头部异常。
+  - 将原 `risk-ranking-grid` 改成图表 + 紧凑明细布局。
+
+- `DigitalEmployeeDashboard.vue`
+  - 给卡片设置 flex 纵向结构，让图表区和列表区可拉伸。
+  - 调整栅格跨度：趋势 7、每日摘要 5；技能分布、模块排行、业务产出各 4；最近记录 12。
+  - 为图表容器增加可填充高度，减少固定高度导致的空白。
+
+- `DigitalEmployeeDailyWorkChart.vue`
+  - 将固定高度改为跟随父容器的 `100%`，用最小高度保证可读性。
+
+## 测试方案
+
+- 前端源码测试：
+  - 风险看板不再暴露常见英文风险 key。
+  - 异常排行包含 `rankingChartItems` 并复用 `BarChart`。
+  - 数字员工看板包含布局填充类名和可拉伸图表区域。
+- 构建验证：
+  - `node web/tests/risk-observation-dashboard.test.mjs`
+  - `node web/tests/digital-employee-dashboard.test.mjs`
+  - `npm.cmd --prefix web run build`
+
+## 验收标准
+
+- 风险看板常见英文 key 在用户可见位置被中文文案替代。
+- 异常排行以图表作为主视觉，不再只是五列文字列表。
+- 数字员工看板主要图表能够跟随卡片高度填充，卡片间高度更均衡。
+- 定向测试和前端构建通过。
+
+## 风险与开放问题
+
+- 当前工作区有大量既有未提交和未跟踪文件，本次提交需要严格隔离目标文件。
+- 若现有测试文件中保留了旧版乱码断言，需要同步更新为 UTF-8 中文断言。
+- 本次不改后端，如果后端后续新增新的风险 key，需要前端映射表继续补充。

+# 风险与数字员工看板视觉优化 TODO
+
+## 调研
+
+- [x] 盘点风险看板英文指标、异常排行和数字员工布局现状。[CONCEPT: 背景与问题] 证据：已检查 `RiskObservationDashboard.vue`、`DigitalEmployeeDashboard.vue`、`DigitalEmployeeDailyWorkChart.vue`、`BarChart.vue` 和相关测试。
+
+## 契约
+
+- [x] 确认本次不改后端接口，只做前端展示归一化和布局优化。[CONCEPT: 目标与非目标] 证据：风险看板和数字员工看板已有所需数据字段。
+
+## 前端
+
+- [x] 扩展风险看板中文化映射，覆盖风险信号、来源、状态、未知值和规则名。[CONCEPT: 功能能力] 证据：新增 `riskLabels.js`，`RiskObservationDashboard.vue` 和 `useOverviewView.js` 已接入统一中文化函数。
+- [x] 将异常排行改为图表化主视觉，并保留紧凑明细。[CONCEPT: 前端方案] 证据：`RiskObservationDashboard.vue` 新增 `rankingChartItems`、`rankingDetailGroups` 和 `risk-ranking-visual`。
+- [x] 优化数字员工看板卡片跨度、等高布局和图表填充。[CONCEPT: 前端方案] 证据：`DigitalEmployeeDashboard.vue` 调整趋势/摘要/最近记录栅格，并新增 `digital-chart-fill`、`digital-card-fill`。
+- [x] 调整数字员工趋势图高度，使其跟随父容器填充。[CONCEPT: 前端方案] 证据：`DigitalEmployeeDailyWorkChart.vue` 高度改为 `100%` 并保留 `min-height`。
+
+## 测试
+
+- [x] 更新风险看板源码测试，覆盖中文化和图表化异常排行。[CONCEPT: 测试方案] 证据：`risk-observation-dashboard.test.mjs` 新增中文化 helper 和排行图表断言。
+- [x] 更新数字员工看板源码测试，覆盖布局填充类名和图表高度策略。[CONCEPT: 测试方案] 证据：`digital-employee-dashboard.test.mjs` 新增填充布局断言。
+- [x] 运行风险看板定向测试。[CONCEPT: 测试方案] 证据：`node web/tests/risk-observation-dashboard.test.mjs`，7 passed。
+- [x] 运行数字员工看板定向测试。[CONCEPT: 测试方案] 证据：`node web/tests/digital-employee-dashboard.test.mjs`，4 passed。
+- [x] 运行前端构建验证。[CONCEPT: 测试方案] 证据：`npm.cmd --prefix web run build` 通过，仍有既有 Rollup 注释和大 chunk 警告。
+
+## 验收
+
+- [x] 确认风险看板可见文案不再暴露常见英文 key。[CONCEPT: 验收标准] 证据：测试覆盖 `duplicate_invoice`、`policy.duplicate_invoice`、`travel`、`rule_center`、`financial_risk_graph` 中文化。
+- [x] 确认异常排行主视觉为图表形式。[CONCEPT: 验收标准] 证据：组件中异常排行由 `BarChart` 的 `rankingChartItems` 驱动。
+- [x] 确认数字员工看板主要图表和卡片减少无效空白。[CONCEPT: 验收标准] 证据：趋势图、饼图、条形图和业务产出卡片均接入可填充容器。
+- [x] 评估提交和推送范围，避免纳入无关脏工作区变更。[CONCEPT: 风险与开放问题] 证据：暂存区限定为分析看板前端、风险标签工具、定向测试和本开发文档，未纳入 `server/storage`、日志、临时截图等无关文件。
