+## 修复记录
+- 09:58：修复费用操作记录 AI 预审图标缺失，并将记录区收敛为企业级审计日志样式。
+  - Git 提交检查：`git fetch --all --prune` 成功；upstream 为 `origin/main`；`HEAD..origin/main` 无新提交；本地相对 upstream ahead 19 个提交。
+  - 本地 ahead 摘要：`07241b46 fix(docker): manage local postgres in default compose`；`787bc3a4 feat(platform): close AI expense value loop`；`242d68c3 feat(approval): add task workflow and waiver decisions`；`28b834ed fix(approval): replay immutable action responses`；`4940ebc4 feat(approval): add safe risk disposition workflow`；`ee88a36b feat(ai): add tenant-safe hierarchical expense learning`；`6bdf65bc feat(expenses): add authoritative pre-review workflow`；`ae3f02c3 feat(expense): add persistent zero-entry receipt association`；`54754b55 feat(ai): add personal expense application memory`；`211f85d9 feat(ai): unify verified expense application workflow`；`5b246307 feat(ai): issue verified application preview decisions`；`a662cfe6 feat(ai): add expense application feedback ledger`；`5ed34c2b feat(expenses): backfill historical claims into expense cases`；`11275e4b fix(migrations): enforce schema ownership safety`；`1347366b feat(expenses): secure timeline and draft events`；`22669a90 feat(expenses): show unified expense event timeline`；`a616b30c fix(expenses): unify AI application submission transaction`；`653eda05 feat(auth): add opaque bearer sessions`；`661990b2 feat(expenses): add transactional expense case events`。
+  - 修改：将 MDI 7.4.47 不存在的 `mdi-shield-search-outline` 替换为 `mdi-shield-check-outline`，并把申请/报销提交图标改为语义更准确的 `mdi-file-send-outline`；补充图标映射回归断言。
+  - 修改：将费用操作记录改为“发生时间 / 事件 / 操作人”三列审计日志，图标并入事件列；移除绿色“最新”成功态误用，改为中性记录数和“最新优先”元数据；统一紧凑行高、方形状态图标、标准字重、语义色与显式响应式网格。
+  - 修改：补充 `aria-labelledby`、`aria-busy`、图标读屏隐藏、操作人完整值提示和刷新按钮键盘焦点样式；事件倒序排序仅对有限时间戳执行数值比较。
+  - 操作：通过项目脚本写入本 bug 日志；生成桌面最终截图、聚焦截图和设计对照证据，并更新根目录 `design-qa.md`。
+  - 验证：`node --test --test-timeout=60000 tests/expense-case-timeline.test.mjs` 通过，13/13；`npm run build` 通过；`git diff --check` 通过；真实申请 `AT4UHTKWU` 浏览器刷新后仍展示两条记录、三列表头与两个有效图标，未进入加载失败状态。
+  - 影响：修复费用申请与报销单 AI 预审事件的空白图标；统一费用操作记录的信息密度、状态语义、可访问性和企业后台视觉风格，不改变后端事件协议或审批业务顺序。
