+2. 成交额缺市场或交易日错位仍误标三市实时数据：只汇总非负金额和一致交易日，公开 `marketCount`、`tradeDate`、`previousTradeDate`，缺市场返回 `partial`。
+3. 空板块目录误标 `fresh`：一级行业为空时直接返回 `unavailable`，且只保留存在相邻两日收盘价和有效涨跌幅的板块。
+4. 前端隐藏 `partial/delayed` 警告：宽度、板块和成交额面板均展示非 `fresh` 状态提示，并展示板块与成交额真实交易日期。
+5. PRD、发布说明和 Review 文档残留旧口径：已同步更正为真实 TDX 宽度、一级行业与成交额趋势口径，主力净流入和新闻仍明确延期。
