 [项目] 星程桑基图
 
 一、已完成（Done）
@@ -17,6 +17,20 @@
 9. 已实现本地持久化：用户上传文件、映射配置与预览选项会写入 localStorage，刷新后自动恢复。
 10. 已新增“汇聚对齐”配置（Between/Middle/Top/Bottom），可控制 target 侧对齐，且 gap 作为源侧基准。
 11. 已优化“无配置初始化映射”：优先按表头别名自动匹配，缺失时按第二行首个数字列兜底。
+12. 已按 Figma 更新主界面布局与文案：
+   - 左侧将“源数据/目标数据”合并为单个“数据选择器”区块，并使用 `select.svg` 标题图。
+   - 新增独立“信息日志”面板（`information.svg`），集中显示解析信息、告警、错误与当前映射日志。
+   - 预览标题改为 `sankeyview.svg`，并移除预览区域底部告警展示。
+13. 已完成总高度适配窗口：页面改为 `header + content + footer` 的 100vh 自适应布局，内容区按剩余空间伸缩并在必要时内部滚动。
+14. 已修复桑基图底部轻微溢出：图表渲染底部新增固定 8px 安全内边距，并同步目标侧布局高度计算。
+15. 已修复 gap 增大时顶部轻微溢出：图表渲染顶部新增固定 8px 安全内边距，并与上下可用高度计算保持一致。
+16. 已增强日志定位能力：当“源数据不是有效数字 / 源描述为空 / 目标描述为空”时，告警会展示行号、列号、列名及该单元格原始值（目标为空时额外提示无可继承上方值）。
+17. 已增强 iOS 预览尺寸同步：增加 `ResizeObserver` 与 `visualViewport` 监听，确保地址栏变化和容器尺寸变化时桑基图实时 resize。
+18. 已调整移动端布局顺序：单列模式下“桑基图预览”位于“数据选择框”之上。
+19. 已修复 iOS 下 preview-panel 高度异常：引入 `visualViewport` 动态高度变量驱动页面高度，并将移动端内容区改为“预览弹性占满 + 选择区独立滚动”布局。
+20. 已完成手机端控件压缩：隐藏上传文本框；工具条单行滚动显示；预览区 gap/padding 改为下拉（0-30 步长 5 / 0-80 步长 10）；方向改为“源/目标”；标签位置改为“内/外/左/右”；汇聚对齐改为“两端/中间/顶部/底部”；控件尽量单行展示。
+21. 已强制手机端仅使用下拉控件模式：手机视口不渲染 gap/padding 滑动条与方向拨杆，仅渲染下拉选择，避免样式条件失效时回退到滑动条模式。
+22. 已扩展到平板单行模式：`<=1024px` 下工具条与预览控件均单行展示（不换行，超出横向滚动），并压缩滑动条宽度以提升一行容纳能力。
 
 二、当前状态（In Progress）
 1. 无进行中的代码重构任务。
@@ -33,12 +47,14 @@
 2. Vite 开发配置依赖本机 HTTPS 证书路径，换机器可能无法直接启动。
 3. 当前“目标数据”无独立数值列，数值始终来自 source data 列；若未来业务需要需先改 PRD。
 4. 小程序仅骨架，尚未接入真实解析、渲染与导出。
+5. 信息日志当前仅展示最近告警（前 8 条），若后续需要完整历史需引入分页或虚拟滚动。
 
 四、下一步建议（Next）
 1. 决策是否引入“目标数值列”能力（先更新 PRD 后实现）。
 2. 将小程序由骨架升级为可用版本（优先复用 `src/core`）。
 3. 补充更多异常用例测试（空文件、超大文件、乱码表头、极端数值）。
 4. 评估并处理 dev HTTPS 证书本地耦合问题，降低新环境接入成本。
+5. 评估“信息日志”是否需要支持导出或清空操作。
 
 五、执行约定（Session Memory Rules）
 1. 新会话开始先读取本文件，再读取 6 份规范文档。
