+# Three Operations Modules Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Add department, region, and customer operations statistics sections to the dashboard, ported from lnoneos prototype with real MySQL data.
+
+**Architecture:** All 3 new API endpoints aggregate from the existing `getVehicles()` cache (no new DB queries). A new macro-region mapping function converts province/city to 华东/华南/etc. The frontend adds 3 new collapsible sections below the existing asset summary table, each with desktop table + mobile card views. The existing vehicle list modal is extended with new filter params (manager, customer, isColdChain, isTrailer).
+
+**Tech Stack:** Hono (backend), React + Tailwind CSS + Motion (frontend), TypeScript throughout.
+
+**Reference:** lnoneos prototype at `/Users/kkfluous/Projects/ai-coding/lnoneos/src/App.tsx`
+

+
+**Files:**
+- Modify: `src/server/routes/vehicles.ts` (add functions after line ~111)
+
+- [ ] **Step 1: Add macro-region mapping function**
+

+
+### Task 2: Backend — Three new API endpoints
+
+**Files:**
+- Modify: `src/server/routes/vehicles.ts` (add endpoints before the `/list` endpoint)
+
+- [ ] **Step 1: Add `/dept-stats` endpoint**
+
+Add before the `VEHICLE_TYPE_FILTERS` const (which is before `/list`) in `src/server/routes/vehicles.ts`:
+
+```typescript

+### Task 3: Backend — Extend `/list` with new filter params
+
+**Files:**
+- Modify: `src/server/routes/vehicles.ts` (the `/list` endpoint)
+
+- [ ] **Step 1: Add manager, customer, isColdChain, isTrailer filters**
+
+In the `/list` endpoint, after the existing `category` filter block, add:
+
+```typescript
+  const { batch, model, location, status, category, vehicleType, manager, customer, isColdChain, isTrailer } = c.req.query();
+```
+
+(Replace the existing destructure line.)

+
+### Task 4: Frontend — Types and API client
+
+**Files:**
+- Modify: `src/types.ts`
+- Modify: `src/api.ts`
+
+- [ ] **Step 1: Add new interfaces to `src/types.ts`**
+
+Append at end of file:
+
+```typescript
+export interface ManagerStats {
+  manager: string;
+  department: string;
+  t4_5: number;
+  t4_5c: number;
+  t18: number;
+  t49: number;
+  trailer: number;
+  other: number;
+  total: number;
+}
+
+export interface DeptGroup {
+  department: string;
+  totalAssets: number;
+  operatingCount: number;
+  idleCount: number;
+  managers: ManagerStats[];
+}
+
+export interface RegionGroup {
+  region: string;
+  totalAssets: number;
+  operatingCount: number;
+  inventoryCount: number;
+  customers: string[];
+  typeBreakdown: { type: string; total: number; operating: number; inventory: number; customers: string[] }[];
+}
+
+export interface CustomerStats {
+  customer: string;
+  manager: string;
+  brand: string;
+  department: string;
+  region: string;
+  city: string;
+  t4_5: number;
+  t4_5c: number;
+  t18: number;
+  t49: number;
+  trailer: number;
+  other: number;
+  total: number;
+}
+```
+
+- [ ] **Step 2: Add API functions to `src/api.ts`**
+
+Add imports at top:
+
+```typescript
+import type {
+  SummaryData,
+  TypeSummary,
+  VehicleListItem,
+  DeptGroup,
+  RegionGroup,
+  CustomerStats,
+} from './types';
+```
+
+Add after `fetchVehicleList`:
+
+```typescript
+export async function fetchDeptStats(): Promise<DeptGroup[]> {
+  return fetchJson<DeptGroup[]>(`${BASE}/dept-stats`);
+}
+
+export async function fetchRegionStats(): Promise<RegionGroup[]> {
+  return fetchJson<RegionGroup[]>(`${BASE}/region-stats`);
+}
+
+export async function fetchCustomerStats(): Promise<CustomerStats[]> {
+  return fetchJson<CustomerStats[]>(`${BASE}/customer-stats`);
+}
+```
+
+Also update `fetchVehicleList` params type to include new filters:
+
+```typescript
+export async function fetchVehicleList(params: {
+  batch?: string;
+  model?: string;
+  location?: string;
+  status?: string;
+  category?: string;
+  vehicleType?: string;
+  manager?: string;
+  customer?: string;
+  isColdChain?: string;
+  isTrailer?: string;
+}): Promise<VehicleListItem[]> {
+  const query = new URLSearchParams();
+  if (params.batch) query.set('batch', params.batch);
+  if (params.model) query.set('model', params.model);
+  if (params.location) query.set('location', params.location);
+  if (params.status) query.set('status', params.status);
+  if (params.category) query.set('category', params.category);
+  if (params.vehicleType) query.set('vehicleType', params.vehicleType);
+  if (params.manager) query.set('manager', params.manager);
+  if (params.customer) query.set('customer', params.customer);
+  if (params.isColdChain) query.set('isColdChain', params.isColdChain);
+  if (params.isTrailer) query.set('isTrailer', params.isTrailer);
+  return fetchJson<VehicleListItem[]>(`${BASE}/list?${query.toString()}`);
+}
+```
+
+- [ ] **Step 3: Verify TypeScript compiles**
+
+Run: `npx tsc --noEmit`
+Expected: no errors
+
+- [ ] **Step 4: Commit**
+
+```bash
+git add src/types.ts src/api.ts
+git commit -m "feat: add frontend types and API client for dept/region/customer stats"
+```
+
+---
+
+### Task 5: Frontend — Extend App.tsx state, data loading, imports, and showPlateNumbers
+
+**Files:**
+- Modify: `src/App.tsx`
+
+- [ ] **Step 1: Update imports**
+
+Replace the existing import lines at top of `src/App.tsx`:
+
+```typescript
+import {
+  Truck,
+  Warehouse,
+  Activity,
+  PlusCircle,
+  MinusCircle,
+  History,
+  ChevronDown,
+  ChevronRight,
+  Info,
+  Loader2,
+  Search,
+  Filter,
+  ArrowRightLeft,
+} from 'lucide-react';
+```
+
+Update type imports:
+
+```typescript
+import type { SummaryData, TypeSummary, VehicleListItem, DeptGroup, RegionGroup, CustomerStats } from './types';
+import { fetchSummary, fetchByType, fetchVehicleList, fetchWeeklyDetail, fetchDeptStats, fetchRegionStats, fetchCustomerStats } from './api';
+```
+
+- [ ] **Step 2: Add new state variables**
+
+After the existing state declarations (after `const [modalLoading, setModalLoading] = useState(false);`), add:
+
+```typescript
+  // Dept/Region/Customer data
+  const [deptData, setDeptData] = useState<DeptGroup[]>([]);
+  const [regionData, setRegionData] = useState<RegionGroup[]>([]);
+  const [customerData, setCustomerData] = useState<CustomerStats[]>([]);
+
+  // Dept section state
+  const [deptViewMode, setDeptViewMode] = useState<'department' | 'manager'>('department');
+  const [expandedDepts, setExpandedDepts] = useState<Set<string>>(new Set());
+  const [expandedManagerDetails, setExpandedManagerDetails] = useState<Set<string>>(new Set());
+  const [selectedManager, setSelectedManager] = useState<string>('All');
+
+  // Region section state
+  const [expandedRegions, setExpandedRegions] = useState<Set<string>>(new Set());
+  const [regionFilters, setRegionFilters] = useState({ region: '', city: '', customer: '' });
+  const [isRegionFilterOpen, setIsRegionFilterOpen] = useState(false);
+
+  // Customer section state
+  const [expandedCustomers, setExpandedCustomers] = useState<Set<string>>(new Set());
+  const [customerFilters, setCustomerFilters] = useState({ customer: '', brand: '', department: '', manager: '', region: '' });
+  const [isCustomerFilterOpen, setIsCustomerFilterOpen] = useState(false);
+```
+
+- [ ] **Step 3: Update loadData to fetch all 3 new endpoints**
+
+Update the `loadData` callback:
+
+```typescript
+  const loadData = useCallback(async () => {
+    try {
+      setLoading(true);
+      setError(null);
+      const [s, byType, dept, region, cust] = await Promise.all([
+        fetchSummary(),
+        fetchByType(),
+        fetchDeptStats(),
+        fetchRegionStats(),
+        fetchCustomerStats(),
+      ]);
+      setSummary(s);
+      setProcessedData(byType);
+      setDeptData(dept);
+      setRegionData(region);
+      setCustomerData(cust);
+      setLastUpdate(new Date().toLocaleString('zh-CN'));
+    } catch (e) {
+      setError(e instanceof Error ? e.message : '数据加载失败');
+    } finally {
+      setLoading(false);
+    }
+  }, []);
+```
+
+- [ ] **Step 4: Extend showPlateNumbers type**
+
+Update the showPlateNumbers state type:
+
+```typescript
+  const [showPlateNumbers, setShowPlateNumbers] = useState<{
+    batch: string;
+    model: string;
+    location: string;
+    category?: 'Inventory' | 'Pending' | 'Delivered' | 'Returned' | 'Replaced' | 'Operating';
+    vehicleType?: string;
+    manager?: string;
+    customer?: string;
+    isColdChain?: boolean;
+    isTrailer?: boolean;
+  } | null>(null);
+```
+
+- [ ] **Step 5: Update modal loading to pass new filter params**
+
+In the `useEffect` for modal loading, update the params block (the "Normal vehicle list" section):
+
+```typescript
+    // Normal vehicle list
+    setModalWeeklyDetail([]);
+    const params: Record<string, string> = {};
+    if (showPlateNumbers.vehicleType) params.vehicleType = showPlateNumbers.vehicleType;
+    if (showPlateNumbers.batch !== 'All') params.batch = showPlateNumbers.batch;
+    if (showPlateNumbers.model !== 'All') params.model = showPlateNumbers.model;
+    if (showPlateNumbers.location !== 'All') params.location = showPlateNumbers.location;
+    if (cat === 'Inventory') params.status = 'Inventory';
+    if (cat === 'Operating') params.category = 'Operating';
+    if (showPlateNumbers.manager) params.manager = showPlateNumbers.manager;
+    if (showPlateNumbers.customer) params.customer = showPlateNumbers.customer;
+    if (showPlateNumbers.isColdChain !== undefined) params.isColdChain = String(showPlateNumbers.isColdChain);
+    if (showPlateNumbers.isTrailer !== undefined) params.isTrailer = String(showPlateNumbers.isTrailer);
+```
+
+- [ ] **Step 6: Add toggle helpers and derived data**
+
+After the existing `toggleModel` function, add:
+
+```typescript
+  const toggleDept = (dept: string) => {
+    const newSet = new Set(expandedDepts);
+    if (newSet.has(dept)) newSet.delete(dept);
+    else newSet.add(dept);
+    setExpandedDepts(newSet);
+  };
+
+  const toggleManagerDetails = (manager: string) => {
+    const newSet = new Set(expandedManagerDetails);
+    if (newSet.has(manager)) newSet.delete(manager);
+    else newSet.add(manager);
+    setExpandedManagerDetails(newSet);
+  };
+
+  const toggleRegion = (region: string) => {
+    const newSet = new Set(expandedRegions);
+    if (newSet.has(region)) newSet.delete(region);
+    else newSet.add(region);
+    setExpandedRegions(newSet);
+  };
+
+  const toggleCustomer = (customer: string) => {
+    const newSet = new Set(expandedCustomers);
+    if (newSet.has(customer)) newSet.delete(customer);
+    else newSet.add(customer);
+    setExpandedCustomers(newSet);
+  };
+
+  // Derived data for dept section
+  const allManagersList = deptData.flatMap((d) => d.managers.map((m) => m.manager)).filter((v, i, a) => a.indexOf(v) === i).sort();
+  const managerStats = deptData
+    .flatMap((d) => d.managers)
+    .filter((m) => selectedManager === 'All' || m.manager === selectedManager)
+    .sort((a, b) => b.total - a.total);
+
+  // Derived data for customer section
+  const filteredCustomerStats = customerData.filter((s) => {
+    const mc = !customerFilters.customer || s.customer.toLowerCase().includes(customerFilters.customer.toLowerCase());
+    const mb = !customerFilters.brand || s.brand === customerFilters.brand;
+    const md = !customerFilters.department || s.department === customerFilters.department;
+    const mm = !customerFilters.manager || s.manager.toLowerCase().includes(customerFilters.manager.toLowerCase());
+    const mr = !customerFilters.region || s.region === customerFilters.region;

+### Task 6: Frontend — Department Operations UI
+
+**Files:**
+- Modify: `src/App.tsx` (add section after the asset summary table's closing `</div>`, before the Plate Number Modal)
+
+- [ ] **Step 1: Add the department operations section**
+
+Insert the department operations section JSX. Reference: lnoneos lines 1362-1880. This section goes right after the closing `</div>` of the asset summary table (`bg-white rounded-sm border...`) and before `{/* Plate Number Modal */}`.
+
+The section includes:
+1. Header with title "部门运营统计"
+2. Dark summary bar (总资产/运营中/闲置中 — skip 平均出勤)
+3. Toggle buttons (按部门 / 按业务员) + manager filter dropdown
+4. Desktop table view (`hidden lg:block`)
+   - Department mode: department rows expandable to show manager cards with 6 vehicle type cells
+   - Manager mode: flat manager rows expandable to show 6 vehicle type cells
+5. Mobile card view (`lg:hidden`)
+
+Port the JSX from lnoneos lines 1362-1880, replacing:
+- `MOCK_DEPT_STATS` → `deptData`
+- `DEPT_TOTALS.total` → `deptData.reduce((s, d) => s + d.totalAssets, 0)`
+- `allManagersList` / `managerStats` / `deptViewMode` / `expandedDepts` / `expandedManagerDetails` / `selectedManager` → already defined in Task 5
+- `setShowPlateNumbers` calls: keep the same structure but remove `source` field (not needed in ln-bi)
+- Remove `ArrowRightLeft` icon usage in toggle buttons — replace with simple text button
+- All `rounded-2xl` → `rounded-sm` to match ln-bi style
+- All `shadow-sm` stay as is
+
+The `setShowPlateNumbers` calls from lnoneos use `manager`, `type`, `isColdChain`, `isTrailer` fields which we added to the state type in Task 5.
+

+### Task 7: Frontend — Region Operations UI
+
+**Files:**
+- Modify: `src/App.tsx` (add section after department section, before Plate Number Modal)
+
+- [ ] **Step 1: Add the region operations section**
+
+Reference: lnoneos lines 1882-2174. Insert after the department section.
+
+The section includes:
+1. Slate-themed header with "区域运营统计" + filter button
+2. Filter popover (客户搜索 / 区域下拉 / 城市下拉)
+3. Desktop table: expandable region rows → vehicle type sub-rows
+4. Mobile cards: expandable region cards with type breakdown
+
+Port the JSX from lnoneos, replacing:
+- `MOCK_CUSTOMER_STATS` region-based filtering → use `filteredRegionData` (from Task 5)
+- Region stats aggregation in lnoneos used mock data with `Math.floor(totalAssets * 0.8)` for operating — use real `r.operatingCount` and `r.inventoryCount`
+- Type breakdown: use `r.typeBreakdown` array from API
+- `uniqueRegions` / `uniqueCities` → already defined in Task 5
+- `setShowPlateNumbers` calls: use `vehicleType` field for type filtering instead of lnoneos's `type` field
+- `rounded-2xl` → `rounded-sm`
+- Filter popover for cities: derive from `regionData` (all unique cities from customers)
+
+Note: The region filter's city dropdown needs city data. Add to Task 5's derived data if not already there. The regionData from API contains customer names but not cities. For the city filter, we can derive from customerData filtered by region.

+- [ ] **Step 1: Add the customer operations section**
+
+Reference: lnoneos lines 2176-2496. Insert after the region section.
+
+The section includes:
+1. Emerald-themed header with "客户运营统计" + filter button
+2. Filter popover (客户名搜索 / 业务员搜索 / 品牌下拉 / 部门下拉 / 区域下拉)
+3. Desktop table: customer rows with 6 vehicle type columns + total, expandable detail cards
+4. Mobile cards: customer cards with expandable vehicle type grid
+
+Port the JSX from lnoneos, replacing:
+- `MOCK_CUSTOMER_STATS` → `filteredCustomerStats` (from Task 5)
+- `DEPT_TOTALS.total` → `customerData.reduce((s, c) => s + c.total, 0)` for asset ratio
+- `setShowPlateNumbers` calls: use `vehicleType` + `customer` fields
+- `uniqueBrands` / `uniqueDepts` / `uniqueRegions` → already defined in Task 5
+- `rounded-2xl` → `rounded-sm`

+# Mileage Backend Refactor Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Refactor `src/server/routes/mileage.ts` (569 lines) into well-typed, modular files with clear responsibilities, eliminating duplicate logic and `as any` casts.
+
+**Architecture:** Split the monolithic route file into: shared types, a reusable vehicle-info query module, a monitoring cache module, and focused route handlers. The API contract (request/response shapes) stays identical — this is a pure internal refactor with zero frontend changes.
+
+**Tech Stack:** Hono, mysql2/promise, TypeScript strict types
+
+---
+
+## File Structure
+
+| File | Responsibility |
+|------|---------------|
+| `src/server/routes/mileage/types.ts` | All interfaces for mileage domain (cache, vehicles, filters, API responses) |
+| `src/server/routes/mileage/vehicle-info.ts` | Shared SQL + helper to build plate→info Map from `lingniu_prod` |
+| `src/server/routes/mileage/cache.ts` | Monitoring cache: refresh logic, data merging, filter precomputation, target mapping |
+| `src/server/routes/mileage/monitoring.ts` | `GET /monitoring` route handler |
+| `src/server/routes/mileage/targets.ts` | `GET /targets`, `GET /target/:id/vehicles` route handlers |
+| `src/server/routes/mileage/trend.ts` | `GET /trend` route handler |
+| `src/server/routes/mileage/index.ts` | Hono app assembly: imports routes, starts cache timer, exports app |
+
+After refactor, delete: `src/server/routes/mileage.ts` (the old monolith).
+
+## Constraints
+
+- **Zero API changes** — all request params and response JSON shapes must remain identical
+- **Zero frontend changes** — `src/modules/mileage/api.ts` and `types.ts` stay untouched
+- **Preserve all existing behavior** including cache refresh interval, date queries, filter logic
+

+# Smart Scheduling (智能调度) Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Build a smart scheduling module that analyzes vehicle mileage assessment data, generates vehicle replacement suggestions using a greedy priority-matching algorithm, and presents an actionable UI for dispatchers.
+
+**Architecture:** Backend Hono routes compute suggestions in real-time by aggregating assessment targets, vehicle mileage, customer daily averages, inventory vehicles, and GPS location data. Frontend React module displays suggestions with batch filtering, priority-sorted list, and a detail modal with before/after comparison. A notify endpoint records dispatcher actions and triggers external callbacks.
+
+**Tech Stack:** Hono (backend), MySQL (mysql2/promise), React 19, Tailwind CSS, motion/react, lucide-react, recharts (optional for future charts)
+
+**Spec:** `docs/superpowers/specs/2026-04-16-smart-scheduling-design.md`

+| `src/server/routes/scheduling/index.ts` | Router entry — mounts suggestions + notify sub-routes |
+| `src/server/routes/scheduling/suggestions.ts` | `GET /` — queries all data sources, runs classification + matching algorithm, returns `SchedulingResponse` |
+| `src/server/routes/scheduling/notify.ts` | `POST /notify` — records action, triggers callback, returns success |
+| `src/server/routes/scheduling/types.ts` | All scheduling-specific TypeScript interfaces |
+| `src/server/routes/scheduling/algorithm.ts` | Pure functions: classifyVehicles, generateSuggestions, vehicle-type matching, region matching |
+
+### Backend (modified files)
+
+| File | Change |
+|------|--------|
+| `src/server/index.ts` | Add `import schedulingRouter` and `app.route('/api/scheduling', schedulingRouter)` |
+| `src/server/routes/vehicles.ts` | Export `mapRegion()` function (currently module-private) |
+
+### Frontend (new files)
+
+| File | Responsibility |
+|------|---------------|
+| `src/modules/scheduling/types.ts` | Frontend type definitions mirroring backend response |
+| `src/modules/scheduling/api.ts` | `fetchSuggestions()`, `sendNotify()` client functions |
+| `src/modules/scheduling/SchedulingModule.tsx` | Main entry — state management, data loading, batch filter, stats cards, list + detail |
+| `src/modules/scheduling/SuggestionList.tsx` | Renders priority-sorted suggestion cards |
+| `src/modules/scheduling/SuggestionDetail.tsx` | Modal with current vehicle info, candidate list with before/after comparison, notify button |
+
+### Frontend (modified files)

+```typescript
+// Add import at top (after existing imports):
+import { Truck, Route, Activity } from 'lucide-react';
+import SchedulingModule from './modules/scheduling/SchedulingModule';
+
+// Update MODULES array to add scheduling:
+const MODULES: ModuleConfig[] = [
+  { id: 'assets', label: '资产管理', icon: Truck, component: AssetsModule },
+  { id: 'mileage', label: '里程管理', icon: Route, component: MileageModule },
+  { id: 'scheduling', label: '智能调度', icon: Activity, component: SchedulingModule },
+];
+```
+
+Also update the Shell.tsx PATH_MAP in `src/components/Shell.tsx`:
+
+```typescript
+const PATH_MAP: Record<string, string> = {
+  '/vehicle': 'assets',
+  '/assets': 'assets',
+  '/mileage': 'mileage',
+  '/scheduling': 'scheduling',

+# 三大运营统计模块设计
+
+从 lnoneos 原型迁移到 ln-bi 生产项目，使用真实 MySQL 数据。
+
+## 架构决策
+
+- **数据源**：复用现有 `getVehicles()` 缓存（~1000 辆，内存聚合无性能问题）
+- **跳过**：出勤率、日均里程（无数据源），QR Code
+- **新增图标**：`Search`, `Filter`, `ArrowRightLeft` (lucide-react，已安装)
+
+## 模块 1：部门运营统计
+
+### 后端 API
+
+**`GET /api/vehicles/dept-stats`** — 返回 `DeptGroup[]`
+
+聚合逻辑：按 `Vehicle.departmentName` 分组，每个部门下按 `Vehicle.customerManager` 分组。每个业务员统计车型分布：
+
+| 车型类别 | 过滤条件 |
+|---|---|
+| t4_5 | type=4.5T 且 model 不含"冷链" |
+| t4_5c | type=4.5T 且 model 含"冷链" |
+| t18 | type=18T |
+| t49 | type=49T |
+| trailer | model 含"挂车" |
+| other | 以上都不是 |
+
+部门级别额外字段：`totalAssets`（运营中的）、`operatingCount`（status=Operating）、`idleCount`（status=Inventory 或 Abnormal）。
+
+### 后端：扩展 `/api/vehicles/list`
+
+新增查询参数：
+- `manager` — 按客户经理筛选
+- `customer` — 按客户名称筛选
+- `isColdChain` — true/false，筛选冷链/非冷链
+- `isTrailer` — true/false，筛选挂车/非挂车
+
+### 前端类型
+
+```typescript
+interface ManagerStats {
+  manager: string;
+  department: string;
+  t4_5: number;
+  t4_5c: number;
+  t18: number;
+  t49: number;
+  trailer: number;
+  other: number;
+  total: number;
+}
+
+interface DeptGroup {
+  department: string;
+  totalAssets: number;
+  operatingCount: number;
+  idleCount: number;
+  managers: ManagerStats[];
+}
+```
+
+### 前端 UI
+
+参照 lnoneos 1362-1880 行：
+- 顶部深色汇总条（总资产/运营中/闲置中，跳过平均出勤）
+- 按部门/按业务员切换
+- 桌面表格 + 移动端卡片
+- 展开部门显示业务员卡片，展开业务员显示 6 个车型格子（可点击下钻到车牌列表）
+
+## 模块 2：区域运营统计
+
+### 后端 API
+
+**`GET /api/vehicles/region-stats`** — 返回 `RegionGroup[]`
+
+新增大区映射函数（province/city → 华东/华南/华北/华中/西南/西北/其他）。按大区分组，每个区域下统计：
+- 按车型（4.5T/18T/49T）的资产/运营/库存数
+- 列出区域内的客户列表
+
+```typescript
+interface RegionGroup {
+  region: string;  // 华东、华南等
+  totalAssets: number;
+  operatingCount: number;
+  inventoryCount: number;
+  customers: string[];
+  typeBreakdown: { type: string; total: number; operating: number; inventory: number; customers: string[] }[];
+}
+```
+
+### 前端 UI
+
+参照 lnoneos 1882-2174 行：
+- 筛选弹出框（客户搜索/区域/城市下拉）
+- 可展开区域行，展开后显示车型子行
+- 桌面表格 + 移动端卡片
+
+## 模块 3：客户运营统计
+
+### 后端 API
+
+**`GET /api/vehicles/customer-stats`** — 返回 `CustomerStats[]`
+
+按 `Vehicle.customerName` 分组（只统计 status=Operating 的车辆），每个客户统计：
+- 关联业务员（customerManager）、品牌（brandLabel）、部门（departmentName）
+- 大区（从 province/city 映射）、城市
+- 6 个车型分列计数 + 合计
+
+```typescript
+interface CustomerStats {
+  customer: string;
+  manager: string;
+  brand: string;
+  department: string;
+  region: string;
+  city: string;
+  t4_5: number;
+  t4_5c: number;
+  t18: number;
+  t49: number;
+  trailer: number;
+  other: number;
+  total: number;
+}
+```
+
+### 前端 UI
+
+参照 lnoneos 2176-2496 行：
+- 筛选弹出框（客户名/业务员搜索，品牌/部门/区域下拉）
+- 翡翠绿色主题表头
+- 客户表格，各车型列可点击下钻
+- 展开后显示 4 个详情卡片（客户详情/主要车型/运营状态/资产占比）
+- 桌面表格 + 移动端卡片
+
+## 文件变更清单
+
+| 文件 | 变更 |
+|---|---|
+| `src/server/routes/vehicles.ts` | 新增 3 个 API 端点 + 扩展 `/list` 的过滤参数 + 大区映射函数 |
+| `src/types.ts` | 新增 `DeptGroup`, `ManagerStats`, `CustomerStats`, `RegionGroup` 接口 |
+| `src/server/types.ts` | 同步新增后端类型 |
+| `src/api.ts` | 新增 `fetchDeptStats`, `fetchRegionStats`, `fetchCustomerStats` |
+| `src/App.tsx` | 新增 3 个 section + 相关 state/toggle/filter 逻辑 + 扩展 showPlateNumbers 类型 |
+
+## 实现顺序
+
+1. 后端：大区映射 + 3 个 API + 扩展 list 过滤
+2. 前端类型 + API 客户端
+3. 部门运营统计 UI
+4. 区域运营统计 UI
+5. 客户运营统计 UI

+# 智能调度模块设计
+
+基于里程考核数据，通过贪心优先级匹配算法，生成车辆替换建议，帮助调度员优化车队里程分布，最大化达标车辆数。
+
+## 业务背景
+
+公司有多批次考核车辆（40台普货、190台冷藏车等），每批次有年度里程考核目标。车辆租赁给不同客户，客户实际使用强度差异大。考核的是**车辆本身的里程**，因此需要通过替换车辆来均衡里程：
+- 高里程客户的已达标车换下来，换上里程缺口大的车（让新车追赶）
+- 低里程客户的无望达标车换下来给高里程客户（抢救），给低里程客户换上已达标的车
+
+## 核心算法
+
+### 车辆分类
+
+从 `tab_mileage_assessment_vehicle` 获取所有考核车辆，按客户聚合计算**客户日均里程**（客户下所有车辆近 30 天日均里程的平均值），然后对每辆车计算：
+
+```
+预测年终里程 = 当前累计里程 + 客户日均里程 × 剩余天数
+达标概率 = 预测年终里程 / 年度目标里程
+```
+
+分为三类：
+
+| 类型 | 条件 | 含义 |
+|------|------|------|
+| qualified | `currentYearIsQualified = true` 或 达标概率 ≥ 120% | 已完成或铁定完成 |
+| hopeless | 达标概率 < 60% | 按当前客户使用强度，年底肯定完不成 |
+| normal | 60% ≤ 达标概率 < 120% | 有希望但不确定，暂不干预 |
+
+### 替换建议生成
+
+**场景 A：replace_qualified（高里程客户的已达标车辆）**
+- 目标：把已达标的车换下来，换上里程缺口大的库存车
+- 候选池：库存车（rent_status='在库'）+ 同车型 + 同区域
+- 排序：优先选剩余缺口最大但换后仍可达标的车
+- 校验：`候选车当前累计 + 客户日均 × 剩余天数 ≥ 年度目标` 才推荐
+
+**场景 B：rescue_hopeless（低里程客户的无望达标车辆）**
+- 目标：把无望车换给高里程客户抢救，给低里程客户换上已达标/库存车
+- 候选池：库存中已达标或将达标的同车型同区域车辆
+- 排序：优先选已达标且里程最高的车（对低里程客户无影响）
+
+### 车型匹配规则
+
+| 源车型 | 可替换为 | 说明 |
+|--------|---------|------|
+| 4.5T冷链 | 4.5T冷链、4.5T普货 | 冷链不开空调可当普货用 |
+| 4.5T普货 | 4.5T普货 | 不能反向替换冷链 |
+| 18T | 18T | 同型号互换 |
+| 49T | 49T | 同型号互换 |
+| 挂车 | 挂车 | 同型号互换 |
+
+### 区域匹配规则
+
+复用已有 `mapRegion()` 函数，将 province/city 映射到大区（嘉兴/广东/北京/新疆/其他）。同一大区内可替换，跨大区不推荐。
+
+### 优先级排序
+
+干预清单排序：
+1. **hopeless + 有可行替换方案** → priority: high（最紧急，还能抢救）
+2. **qualified + 高里程客户 + 有库存可换** → priority: medium（释放达标车，让新车追赶）
+
+## 后端 API
+
+### GET /api/scheduling/suggestions
+
+获取调度建议列表。每次请求实时计算（不使用定时缓存），因为用户操作后需要立即看到最新结果。
+
+**请求参数**：
+
+| 参数 | 类型 | 说明 |
+|------|------|------|
+| targetId | number (可选) | 按批次筛选，不传则全部 |
+
+**响应**：
+
+```typescript
+{
+  summary: {
+    qualifiedCount: number;      // 已达标车辆数
+    hopelessCount: number;       // 无望达标车辆数
+    suggestionCount: number;     // 可干预建议数
+    estimatedGain: number;       // 预计干预后可新增达标数
+  };
+  suggestions: SchedulingSuggestion[];
+  targets: { id: number; name: string; vehicleCount: number }[];
+}
+```
+
+`SchedulingSuggestion` 结构：
+
+```typescript
+{
+  id: string;                    // 建议唯一ID（如 "s-{plate}-{timestamp}"）
+  priority: 'high' | 'medium';
+  type: 'replace_qualified' | 'rescue_hopeless';
+
+  currentVehicle: {
+    plateNumber: string;
+    targetId: number;
+    targetName: string;          // 所属批次
+    vehicleType: string;         // "4.5T冷链" / "18T" 等
+    totalMileage: number;
+    completionRate: number;      // 0-1
+    yearTarget: number;          // 年度目标里程
+    region: string;              // 大区（嘉兴/广东等）
+    province: string;            // 原始省份
+    customer: string;
+    customerAvgDaily: number;    // 客户日均里程
+    predictedYearEnd: number;    // 预测年终里程
+    daysLeft: number;
+  };
+
+  candidates: {
+    plateNumber: string;
+    targetId: number | null;     // 库存车可能无批次
+    targetName: string | null;
+    vehicleType: string;
+    totalMileage: number;
+    completionRate: number;
+    yearTarget: number | null;
+    region: string;
+    province: string;
+    mileageGap: number;          // 剩余缺口
+    predictedAfterSwap: number;  // 换到该客户后预测年终里程
+    canQualifyAfterSwap: boolean;
+  }[];
+
+  reason: string;                // 建议原因文案
+}
+```
+
+### POST /api/scheduling/notify
+
+发送替换通知。成功后前端立即重新拉取 suggestions。
+
+**请求体**：
+
+```typescript
+{
+  suggestionId: string;
+  currentPlate: string;
+  candidatePlate: string;
+}
+```
+
+操作人从 JWT auth 中获取。
+
+**响应**：`{ success: boolean; message: string }`
+
+**行为**：调用外部回调接口发送通知（具体回调 URL 后续配置）。成功后在本地记录已操作状态，后续 GET suggestions 时排除已操作的建议。
+
+### 数据查询流程
+
+后端一次请求聚合以下数据：
+1. 所有考核车辆 — `tab_mileage_assessment_vehicle`（里程进度、达标状态）
+2. 所有考核目标 — `tab_mileage_assessment_target`（批次名称、年度目标）
+3. 库存车辆 — `tab_truck WHERE truck_rent_status = 0`（在库）+ 同表获取车型
+4. 车辆实时位置 — `tab_truck_remote_sync_realtime_info`（province, city）
+5. 合同/客户信息 — 复用 `vehicle-info.ts` 已有的 JOIN 查询
+6. 客户日均里程 — 按客户聚合 `v_vehicle_daily_stats` 近 30 天均值

+
+### UI 设计要求
+
+- 以原型 `SmartSchedulingView` 组件为基础风格
+- 使用 ui-ux-pro-max 优化视觉质量
+- 适配移动端（竖屏卡片流）和 Web 端（landscape 横屏大表格）
+- 干预详情弹窗需截图友好：完整卡片布局、替换前后对比一屏可见、关键数据醒目
+- 统计卡片区保持与原型一致的三列 grid 布局
+- 批次选择器横向滚动 pill 按钮样式
+
+### 技术栈
+
+复用项目已有：React 19 + Tailwind CSS + motion/react（动画）+ recharts（图表）+ lucide-react（图标）
+
+## 约束与边界
+
+- 替换仅为建议，不直接操作数据库修改车辆归属
+- 不能推荐已租赁给其他客户的车辆，只从库存（在库）中推荐
+- 跨批次可替换，但车型必须匹配（含冷链→普货单向规则）
+- 同大区内替换，不跨大区
+- notify 操作后数据立即更新（不使用定时缓存）
+- 客户名称展示需使用已有的脱敏/Blur 组件
