 - 新增累計盈虧指標：`cumulativePnlNative = floatingPnlNative + realizedPnlNative + accumulatedDividendsNative`、`cumulativePnlPercent = cumulativePnlNative / totalBuyCostNative * 100`。
 - SELL 交易的已實現盈虧計算從 CNY 基準改為 Native 基準，CNY 計算保留用於前端兼容展示。
 
+## Dashboard 流水下鑽明細與行內 CRUD (Task 41b)
+- 完成 Dashboard 流水下鑽功能，支持在資產列表中直接查看、修改和刪除歷史交易流水。
+- 在主行 `TableRow` 下方，根據 `expandedIds[pos.assetId]` 條件渲染第二個子行，使用 `<TableCell colSpan={8} className="p-0">` 確保子行佔滿整行寬度。
+- 構建流水明細次級表格：遍歷 `pos.transactions` 數組，表頭為「交易日期 | 類型 | 價格/數量 | 手續費 | 備註 | 操作」，精確渲染每筆交易的歷史數據。
+- 實裝 `UpdateTransactionDialog` 組件：「修改」按鈕打開彈窗並回顯該筆流水數據（數量、價格、手續費、幣種、執行時間），提交後調用 `updateTransaction` Action 並刷新頁面。
+- 實裝行內刪除功能：「刪除」按鈕彈出確認對話框，確認後調用 `deleteTransaction` Action 並刷新頁面。
+- 在 `portfolio.ts` 的 `TransactionRecord` 接口中補充 `id` 和 `fee` 字段，並在下發數據時包含完整的流水 ID，以支持行內 CRUD 操作。
+- UI 優化：為展開的子表格添加左側彩色邊框 (`border-l-4 border-primary/20`) 與左側縮進 (`ml-2`) 增強層級感；展開/收起按鈕文字根據狀態動態切換（「收起」/「展開」）。
+
+## Dashboard 表格化基礎重構 (Task 41)
+- Dashboard 完成表格化基礎重構，徹底移除原有的卡片網格佈局，改用 shadcn/ui Table 組件構建高密度專業券商風格主表。
+- 實裝了基於 ID 的行展開狀態管理邏輯：`useState<Record<string, boolean>>` 控制每行的展開/收起狀態，點擊行或展開按鈕觸發 `toggleExpand`。
+- 表頭嚴格對齊專業標準：名稱/代碼 | 現價 | 市值 | 持倉 | 攤薄/成本 | 浮動盈虧 | 累計盈虧 | 操作。
+- 操作列包含展開/收起指示器與「添加」按鈕，點擊打開 `AddTransactionDialog` 並預選對應資產。
+- 展開行內嵌交易記錄子表格，展示每筆交易的類型、數量、價格、手續費、幣種與日期。
+- 重構 `AddTransactionDialog` 組件支持外部控制開關（`open`/`onOpenChange`/`defaultAssetId` props），同時保持向後兼容內部狀態管理模式。
+- Dashboard 頁面轉換為客戶端組件，使用 `useEffect` 在客戶端加載組合數據。
+
 ## 全面重構資產展示 UI (Task 39)
 - UI 全面升級，復刻專業券商級數據排版，合併攤薄/成本，引入原生幣種盈虧百分比展示。
 - 徹底清理所有帶 (CNY) 和 (USD) 混雜的舊布局，所有 Native 金額根據 `baseCurrency` 渲染正確貨幣符號（USD→$、CNY/HKD→HK$、JPY→¥）。
