-## 2025-08-08 用户画像详情页与筛选能力完善
-- 目标：完成用户画像详情页的移动端组件化实现，补齐 Slider 组件，确保不再有占位符导致的运行问题；对接 /api/users?id= 获取单体详情。
-- 变更文件：
-  - components/user-portrait/mobile/section.tsx（新增）
-  - components/user-portrait/mobile/profile-header.tsx（新增）
-  - components/user-portrait/mobile/metrics-rfm.tsx（新增）
-  - components/user-portrait/mobile/interactions-list.tsx（新增）
-  - components/user-portrait/mobile/purchase-history.tsx（新增）
-  - components/user-portrait/mobile/wechat-accounts.tsx（新增）
-  - app/user-portrait/[id]/page.tsx（新增）
-  - components/ui/slider.tsx（补齐实现）
-- 接口与数据：
-  - 使用 GET /api/users?id= 获取详情，仍由 mock 数据驱动，后续替换为真实库与身份合并。
-- 完成度：本阶段 90%（已完成 UI 与数据对接；待补：AI 画像解读与行动建议、真实库接入）。
-- 下一步：接入真实数据库与 IdentityService，完善筛选抽屉更多维度，详情页增加 AI 标签与建议面板（基于 AI SDK）。
+## 2025-08-08 构建修复与优化
+本次更新内容：
+- 修复构建失败：实现并导出 Toast 模块，补齐 Toaster 组件，解决 "module does not provide an export named 'Toast'"。
+- 新增骨架屏组件：components/ui/skeleton.tsx，用于统一加载态。
+- 补齐 Suspense 边界：新增 app/workspace/moments-sync/[id]/edit/loading.tsx，避免 useSearchParams 触发的路由级 Suspense 报错。
+开发说明：
+- 遵循 App Router 规范，路由级 loading.tsx 作为 Suspense fallback。
+- UI 组件按 shadcn 风格实现，导出点与项目现有 use-toast 保持一致，避免命名不匹配。
+进度汇报：
+- 本次修复完成度：100%
+- 下一步计划：1）巡检所有 useSearchParams 使用点并补齐 loading.tsx；2）在 CI 阶段增加构建前校验；3）联调真实数据源前的接口契约校验。
