+### C-20260924-09｜部署制作工作区编辑至生产服务器
+
+- 日期：2026-09-24
+- 类型：部署
+- 需求与原因：将已推送的课程制作工作区编辑功能部署到生产服务器。
+- 修改范围：部署提交 `866412f` 对应镜像到 `47.93.193.127:/opt/xinghen`，仅重建 `xinghen-app-1`；部署前数据库备份保存为 `/opt/xinghen/.deploy/pre-redeploy-866412f-20260924113445.dump`。未修改反向代理配置；PostgreSQL 与上传卷保留。
+- 保留/新增判断：遵守 D-007 至 D-010。生产数据库迁移由应用启动逻辑执行；数据库卷 `xinghen_postgres_data` 与上传卷 `xinghen_uploads_data` 不重建。
+- 功能确认状态：部分确认
+- 验证证据：`pnpm run check`、`pnpm run build`、`docker buildx build --platform linux/amd64 --pull --load` 通过；生产应用容器运行镜像 SHA `0ff8774dd3195b561027c6907fcfcee91d5cf296d384a7050b941332acd2c849`，状态为 running；PostgreSQL 健康，上传卷仍挂载到 `/app/uploads`。`https://xinghen.work/api/health` 返回 200 与 `{"ok":true}`，首页返回本次构建静态资源 `main-fVQOLHwP.js` 和 `main-CEdAkTL-.css`，HTTP 跳转 HTTPS 为 301，证书 SAN 包含 `xinghen.work`。
+- 未确认与风险：未使用真实平台管理员账号在公网完成课程编辑、分集与素材修改、成员端刷新回看等业务验收；新数据库迁移仅由应用启动执行，未在生产逐项检查新增数据结构。
+- 后续修改提示：后续继续验证平台编辑与成员端读取同一课程内容、鉴权文件访问以及编辑与结单竞态；数据库或上传卷仍按 D-007、D-008 保护。
+- 关联：C-20260924-06；部署提交 `866412f`。
+
+### C-20260924-10｜简化课程、讲师及管理界面信息层级
+
+- 日期：2026-09-24
+- 类型：样式 / 功能
+- 需求与原因：用户确认按五项建议简化整个系统界面，减少课程列表、课程详情、数字讲师、机构管理和平台后台的首屏信息与并列入口。
+- 修改范围：`src/pages/Dashboard.tsx` 将课程列表收敛为名称、状态、最近更新和下一步，并按需展开排序；`src/pages/CourseWorkspace.tsx` 增加阶段提示及可展开课程资料；`src/pages/DigitalInstructorsPage.tsx` 将讲师备注、归属和创建时间放入“更多”；`src/pages/OrganizationManage.tsx` 按课程、成员、账单分区，成员新增入口展开后显示创建账号与邀请链接；`src/pages/admin/AdminLayout.tsx` 将平台入口按课程制作、人员与组织、运营分组；`src/styles.css` 补充布局与窄屏样式。
+- 保留/新增判断：保留 D-001、D-004、D-005、D-009。此次仅调整前端呈现与导航，原有接口、角色鉴权、积分流水和课程操作路径仍由服务端约束；被收起的信息保留可查入口。
+- 功能确认状态：部分确认
+- 验证证据：`pnpm run check`、`pnpm run build`、`git diff --check` 通过；逐项核对页面代码中的入口、分区、链接和状态条件。
+- 未确认与风险：本轮未使用真实个人、组织管理员及平台管理员账号进行浏览器端交互与窄屏目视验收；未部署公网。特别需要核对课程不同状态的提示、机构分区切换及平台导航下拉在实际浏览器中的呈现。
+- 后续修改提示：部署前用三类账号检查课程、讲师、成员和账单路径，并保留各角色原有可访问范围；若调整隐藏区域，不得让业务操作失去可发现入口。
+- 关联：C-20260924-05、C-20260924-07、C-20260924-08。
