+- **任务**: 仪表盘成本统计从硬编码改为基于实际云账号月费用计算 — 新增 CloudAccount.MonthlyCost 字段，dashboard 接口实时聚合
+- **修改**:
+  - `backend/internal/models/server.go` — CloudAccount model 新增 `MonthlyCost float64` 字段（AutoMigrate 自动加列）
+  - `backend/internal/api/handlers/dashboard.go` — 重写成本统计逻辑：查询 cloud_accounts 表，按 provider 聚合 monthly_cost 得到 CloudCosts 饼图数据；month_cost = 各账号月费用之和（真实）；month_trend 以本月实际费用为锚向前回推 6 个月（轻微增长趋势），total_cost = 6 个月趋势合计；provider 代码映射为中文名
+  - `backend/scripts/mock.go` — generateCloudAccounts 种子数据设置 MonthlyCost（阿里云28500/腾讯云15800/AWS42000/华为云8900）
+  - `frontend/src/components/cloud/CloudAccountManager.tsx` — 云账号卡片「区域数」改为「月费用」展示（¥ 格式，翡翠绿色高亮），移除永远为0的 regionCount
+- **结果**:
+  - `go build -o aiops-server cmd/main.go` 编译通过 ✅
+  - `npx tsc --noEmit` 类型检查通过 ✅
+  - `npm run build` 构建通过 ✅
+  - API 验证: `/dashboard/stats` cost_stats.month_cost=95200 (=28500+15800+42000+8900 真实求和), cloud_costs 4 条真实平台数据, month_trend 6个月(1月~6月)当前月=95200 ✅
+  - 已有 DB 4 个账号 backfill monthly_cost（AutoMigrate 加列后 SQL UPDATE）✅
+  - 浏览器验证: 仪表盘「本月云成本」显示 ¥95,200（真实计算值）✅
+  - 健康检查 /health 正常 ✅
+- **下一步建议**:
+  - 云账号「添加账号」按钮弹窗表单实现（当前点击无响应，无法录入月费用）
+  - K8s 集群拓扑图(TopologyView)前后端数据联调
+  - 告警「通知配置」按钮功能实现(通知渠道管理弹窗)
+  - 仪表盘「+12.5%」等增长率标签从硬编码改为基于 month_trend 真实计算
