+# MarkClosePnl 字段语义统一：决策文档
+
+> **状态**：待团队决策 | **日期**：2026-06-26 | **前置**：[互换分红损益字段语义与重复计算分析.md](./互换分红损益字段语义与重复计算分析.md)、修复提交 `ab70531f`（2026-06-26，MarkClosePnl 不再含分红）
+
+---
+
+## 一、问题背景：一个字段，三种语义
+
+`swap_flow_event.MarkClosePnl`（浮动端平仓盈亏·盯市）在历史上**同时承担了三个互斥的职责**，导致各处使用公式不一致。2026-06-26 的修复（`ab70531f`）让它"不再含分红"，但**消费端的公式没有同步调整**，新数据下会产生新的偏差。
+
+### MarkClosePnl 的三种历史语义
+
+| 语义 | 含义 | 谁在用 |
+|---|---|---|
+| **A. 纯价差盯市** | `MarkClosePnl = (平仓价-成本价)×量` | 修复后（`ab70531f`）的目标语义 |
+| **B. 价差+费+分红 总和** | 历史上前端 `calcFloatClosePnl` 把费和分红加进去 | 界面"浮动"列（用户误以为是总盈亏）|
+| **C. 收益计算基数** | 各处用不同公式减/不减分红得到 PosiPnl | 结算单、收益列表 |
+
+**根因**：2024-05-09 从山证 v2.3.0 拷贝（`f9d8a256`）时，`MarkClosePnl` 入库的就是 B（总和），但后续不同开发者按各自理解写了 C 的多种公式，造成不一致。
+
+---
+
+## 二、各处使用现状与不一致清单（含引入时间）
+
+### 2.1 写入点（MarkClosePnl 怎么生成）
+
+| 位置 | 公式 | 引入 | 语义 |
+|---|---|---|---|
+| `SwapDealService.cs:1101` 自动平仓 | `(平仓价-成本价)×量` | `f9d8a256` 2024-05-09 | **修复后=纯价差** |
+| `SwapDealService.cs:1103` 自动平仓(加费) | 上面 `+费×-1` | `f9d8a256` | 修复后=价差-费 |
+| `SwapEodPositionService.cs:463` 自动互换分红 | `=0`（修复前=`PosiDividendSum`）| `ab70531f` 2026-06-26 | **修复后=0（不含分红）** |
+| 前端 `incomeSwapTrade.js:133` 手动互换 | `calcFloatClosePnl` 去 `+DividendIn` | `ab70531f` | **修复后=纯价差** |
+| 前端 `unwindSwapTrade.js:203` 手动平仓 | 同上 | `ab70531f` | **修复后=纯价差** |
+
+> **关键**：`ab70531f` 已把 4 个写入点统一为"纯价差/价差-费"，不含分红。
+
+### 2.2 消费点（PosiPnl / 收益公式）—— ⚠ 不一致集中区
+
+| # | 位置 | 公式 | 减分红? | 引入 | 修复后影响 |
+|---|---|---|---|---|---|
+| ① | `SwapFlowEvent.cs:384` | `PosiPnl = MarkClosePnl - TradingFee` | **否** | `f9d8a256` 2024-05-09 | 新数据偏大（没减分红）|
+| ② | `TradeSettleBillGenerator.cs:110` 结算单 | `PosiPnl = -(MarkClosePnl - tradingFee - DividendIn)` | **是** | `48cf0592` 2026-05-06 | **新数据多减一份分红** ⚠ |
+| ③ | `SwapFlowEventService.cs:528` 收益列表 | `PosiPnl = MarkClosePnl - TradeFee - DividendIn - TradingFee` | **是** | `829334a4` 2025-05-30 | **新数据多减一份分红** ⚠ |
+
+**核心风险（②③）**：修复前 MarkClosePnl 含分红，减去 DividendIn 正好还原纯价差；修复后 MarkClosePnl **不含**分红了，再减 DividendIn 就**多减了一份**，结算单和收益列表金额偏小。
+
+### 2.3 当"总和"用的地方
+
+| 位置 | 公式 | 引入 | 含义 |
+|---|---|---|---|
+| `SwapEodPositionService.cs:681` | `amount = MarkClosePnl + CloseFee + DividendIn` | `f9d8a256` 2024-05-09 | 判是否产生资金记录（三者总和）|
+| `SwapFlowEventService.cs:529` | `NetSettmentAmount = MarkClosePnl + InterestClosePnL` | `083848fb` 2025-05-28 | 净结算额 |
+| `SwapEodPositionService.cs:1610` | `TdCloseMtmPnl = Σ MarkClosePnl` | `f9d8a256` 2024-05-09 | eod 盯市列累加 |
+
+### 2.4 界面展示（eventlist/SwapflowList/EodPositionRisks）
+
+"浮动端平仓盈亏"在界面**拆成 3 个独立列**，没有"总和"列：
+- `MarkClosePnl` → 列名"浮动端平仓盈亏·**浮动**"
+- `DividendIn` → 列名"浮动端平仓盈亏·**分红**"
+- `CloseFee` → 列名"浮动端平仓盈亏·**费用**"
+
+> 用户历史上看到的"浮动列"= 总盈亏，是 buggy 的 MarkClosePnl 凑出来的；修复后该列=纯价差，会变小。**"三者总和"从未有独立列**。
+
+---
+
+## 三、历史数据问题
+
+已入库的 `swap_flow_event.MarkClosePnl` 不可逆——**历史记录含分红，新记录不含**。这意味着任何消费点公式，对历史和新数据只能选一种正确：
+
+| 公式策略 | 历史数据(含分红) | 新数据(纯价差) |
+|---|---|---|
+| 不减 DividendIn（如 ①）| 偏大 | 偏大 |
+| 减 DividendIn（如 ②③）| 正确（抵消）| **偏小（多减）** |
+
+**没有一种公式能同时让历史和新数据都对**，除非：
+- (a) 数据迁移：刷新历史 MarkClosePnl 还原为纯价差，或
+- (b) 加版本标记：区分"修复前/后"的事件，分别用不同公式
+
+---
+
+## 四、三种改法方案（供团队选择）
+
+### 方案一：修正消费点公式（最小改动，推荐作为第一步）
+
+**做法**：把 MarkClosePnl 的语义**正式定为"纯价差盯市"**，修正 ②③ 去掉 `-DividendIn`：
+
+| 位置 | 改动 |
+|---|---|
+| ② `TradeSettleBillGenerator.cs:110` | `-(MarkClosePnl - tradingFee)`（去掉 -DividendIn）|
+| ③ `SwapFlowEventService.cs:528` | `MarkClosePnl - TradeFee - TradingFee`（去掉 -DividendIn）|
+| ① `SwapFlowEvent.cs:384` | 保持，或补 `-DividendIn` 与 ③ 统一（需业务确认收益口径）|
+
+- ✅ **优点**：改动小（3 行），新数据全部正确，语义立即清晰
+- ⚠ **缺点**：**历史数据仍不一致**（见第三节），需配合数据迁移或接受历史偏差
+- 🎯 **适合**：快速止血，让修复（ab70531f）真正生效，不让新数据出错
+
+### 方案二：数据迁移 + 方案一（彻底统一）
+
+**做法**：在方案一基础上，对历史 `swap_flow_event` 执行数据迁移：
+
+```sql
+-- 把历史 MarkClosePnl 还原为纯价差（减去当时混入的分红和费）
+UPDATE swap_flow_event
+SET MarkClosePnl = MarkClosePnl - DividendIn - CloseFee
+WHERE EventType IN (2,3,4) AND DataState = 100
+  AND EventDate < '2026-06-26';  -- 修复提交前的事件
+```
+（实际迁移需先 SELECT 验证范围、备份、分批执行）
+
+- ✅ **优点**：历史与新数据语义完全统一，所有公式一套即可
+- ⚠ **缺点**：改库有风险，需备份+回滚预案；eod 历史表（RealizedMtmPnL 等）是否也需重算需评估
+- 🎯 **适合**：团队接受改历史数据，追求长期干净
+
+### 方案三：新增 TotalClosePnl 字段，职责分离（最长远正确）
+
+**做法**：让每个字段职责单一：
+1. `MarkClosePnl` 永远=纯价差（修复已做到，语义固定）
+2. 新增 `[NotMapped] decimal TotalClosePnl => MarkClosePnl + DividendIn + CloseFee`，专给"总和"场景（结算单、资金记录判断、界面总和列）
+3. 界面如需"总盈亏"列，显式绑定 `TotalClosePnl`，而非靠 MarkClosePnl 隐式承担
+
+- ✅ **优点**：根除"一字段三语义"债务，未来不会再出现"改一处引发另一处偏差"
+- ⚠ **缺点**：改动面最大（涉及结算单/资金记录/界面多处），需排期
+- 🎯 **适合**：作为技术债治理的长期目标，可与方案一/二分阶段实施
+
+---
+
+## 五、建议路径
+
+**推荐分阶段推进**，兼顾止血与长期：
+
+1. **立即（方案一）**：修正 ②③ 消费点公式，避免修复后新数据出错（结算单/收益金额偏小）。这是 `ab70531f` 修复的必要补全，不做的话修复只做了一半。
+2. **近期（方案二）**：评估数据迁移可行性，统一历史数据语义。
+3. **中期（方案三）**：引入 TotalClosePnl，彻底消除语义债务。
+
+---
+
+## 六、需团队决策的问题
+
+1. **收益（PosiPnl）口径**：① 不减分红、②③ 减分红——哪个是业务正确的"收益"定义？（决定公式统一方向）
+2. **历史数据**：是否接受数据迁移（方案二）？还是接受历史偏差、只保证新数据正确？
+3. **界面"总盈亏"列**：是否需要显式新增一列展示 `MarkClosePnl+DividendIn+CloseFee` 总和？（决定是否走方案三）
+4. **实施优先级**：方案一是否立即执行（它阻塞 ab70531f 修复的完整生效）？

+# 互换交易价格字段存储与显示规范
+
+> 本文档总结互换交易（收益互换）中"标的价格"类字段在**录入、入库、展示**三个环节的处理规则，以及债券类与普通（非债券）类的差异。
+> 该规则是 2026-06 一系列价格显示 Bug 排查后总结的结论，供后续开发维护参考，避免再次出现"多除/少乘 100"类问题。
+
+---
+
+## 一、核心规则速查
+
+| 标的类型 | 录入存库 | 入库基准 | 展示规则 |
+|---------|---------|---------|---------|
+| **普通债券类收益互换**（债券标的，如 180205.IB） | 用户输入值 ÷ 100 存库（**相对价**） | 相对价，如 `1.02`（对应输入 102） | 相对价 × 100 展示，如 `102.00000%` |
+| **普通收益互换**（非债券标的，如 ETF、商品） | 用户输入值原样存库 | 绝对价，如 `100`（对应输入 100） | 原样展示，如 `100.00000` |
+
+**一句话**：债券类的价格，库里存"相对价（÷100）"，界面显示时"×100 还原"。普通非债券类输入什么就存什么、显示什么。
+
+---
+
+## 二、为什么债券类要 ÷100 / ×100
+
+债券价格习惯用"面值的百分比"表达（全价 102 元 = 面值 100 的 102%）。
+为了与其他利率/收益率类字段在库里保持"小数形式（1.02）"统一，录入时由 `vue-number-input` 组件自动 ÷100 转成相对价存库；展示时再 ×100 还原成用户习惯的百分比形式。
+
+---
+
+## 三、关键字段与所在表
+
+互换涉及的价格字段命名容易混淆（有的字段名是"期末语义"但实际装的是"期初值"），现梳理如下：
+
+### swap_position 表（期初持仓，`IsInitial=1`）
+
+| 字段 | 含义 | 备注 |
+|------|------|------|
+| `PosiGrossPrice` | 期初全价（不含费） | 相对价基准（债券为 1.02 形式） |
+| `PosiNetPrice` | 期初净价（含费） | 相对价基准 |
+| `PosiNetNoFeePrice` | 成交净价（不含费），**可空** | 收益结算页"期初净价"列取此字段；为空时需回退到 `PosiNetPrice` |
+| `PosiNetFeePrice` | 成交净价（含费），**可空** | |
+
+### swap_flow_event 表（互换/平仓/自动互换事件）
+
+| 字段 | 含义 | 是否入库 | 备注 |
+|------|------|---------|------|
+| `TradingAmountAvg` | 成交均价（期末全价） | ✅ 入库 | 债券类存相对价 |
+| `TradingAmountNetAvg` | 成交净价（不含费） | ✅ 入库（可空） | 字段名像"期末"，但收益结算初始化时装的是**期初净价** |
+| `TradingAmountNetFeeAvg` | 成交净价（含费） | ✅ 入库 | |
+| `TradingAmount` | 成交金额 | ✅ 入库 | = `TradingAmountAvg × Quantity × ContractSize`（后端计算） |
+| `PosiGrossPrice` | 期初全价 | ❌ `[NotMapped]` 不入库 | 运行时从 `swap_position` 拷贝 |
+| `PosiNetPrice` | 期初净价 | ❌ `[NotMapped]` 不入库 | 运行时从 `swap_position` 拷贝 |
+| `UnderlyingInstrumentType` | 标的类型 | ✅ 入库 | **展示时判断是否债券（决定 ×100）的关键字段，生成事件时必须赋值** |
+
+> ⚠️ `PosiGrossPrice` / `PosiNetPrice` 在 `swap_flow_event` 里是 `[NotMapped]`，**数据库查不到这两列**，只在运行时从 `swap_position` 拷贝。所以"期初价"展示的实际数据源是 `swap_position`，不是 `swap_flow_event`。
+
+### eod_swap_position 表（日终持仓）
+
+`PosiDividendSum`（浮动端未实现分红收益）≠ 0 时，会触发分红型自动互换（`DealDividends`）。
+
+---
+
+## 四、各环节的代码实现位置
+
+### 1. 录入（TradeEdit.cshtml + swapTradeEdit.js）
+
+债券类与普通类用**不同的输入格式器**（只是配置开关），真正的 ÷100 转换在 `FastVue.parseNumber` 里执行：
+
+```html
+<!-- 普通债券类收益互换: percent:true, 输入102 → v-model=1.02 (÷100) -->
+<vue-number-input v-model="item.PosiGrossPrice" v-bind:format="inputFormatMarginRateNoPercent">
+
+<!-- 普通收益互换(非债券): percent:false, 输入100 → v-model=100 (原样) -->
+<vue-number-input v-model="item.PosiGrossPrice" v-bind:format="inputFormatTradeSinglePrice">
+```
+
+格式器定义（swapTradeEdit.js，仅配置开关）：
+- `inputFormatMarginRateNoPercent`：`percent: true`（注意：名字里的 "NoPercent" 指"显示时不带%号"，而非"不做换算"，容易误解）
+- `inputFormatTradeSinglePrice`：`percent: false`
+
+**÷100 的真正实现**（`statics/bundles/bundle.js` 的 `FastVue.parseNumber`）：
+```js
+FastVue.parseNumber = function (val, percent) {
+    // ...
+    let isPercent = val.endsWith('%') || percent == true;  // format.percent=true 时
+    let number = new Number(val.replace(/%+$/, ''));
+    return isPercent ? number / 100 : number;   // ← ÷100 在这里执行
+};
+```
+即：组件本身基于第三方库（打包进 bundle.js），但 `percent:true` 时 `number / 100` 的换算是项目自定义的 `FastVue.parseNumber` 实现的，不是第三方库原生行为。
+
+### 2. 展示（TradeView.cshtml）
+
+互换 Tab（浮动收益端）对期初/期末价的处理，**依赖 `UnderlyingInstrumentType` 判断是否债券**：
+
+```cshtml
+@{
+    // 关键: multiplier 由标的类型决定, 债券=100, 非债券=1
+    var multiplier = ConsGlobal.InstrumentType.IsBond(closeFloat.UnderlyingInstrumentType) ? 100 : 1;
+}
+@if (isBond) {
+    <td>@((closeFloat.PosiGrossPrice * multiplier).OtcFormat(OtcFormatFlag.umprice))</td>
+    <td>@((closeFloat.TradingAmountAvg * multiplier).OtcFormat(OtcFormatFlag.umprice))</td>
+} else {
+    <td>@(closeFloat.PosiGrossPrice.OtcFormat(OtcFormatFlag.umprice))</td>
+    <td>@(closeFloat.TradingAmountAvg.OtcFormat(OtcFormatFlag.umprice))</td>
+}
+```
+
+> 🔑 **`UnderlyingInstrumentType` 是展示层判断的关键**。所有生成 `swap_flow_event` 的地方都必须赋值这个字段，否则 `IsBond` 判断失败，债券标的会走非债券分支（不 ×100），导致显示成相对价（1.00 而非 100.00）。
+
+### 3. 收益结算页（SwapIncome.cshtml + incomeSwapTrade.js）
+
+前端 `priceFormat()` 同样 `× multiplier`：
+
+```js
+priceFormat(price) {
+    price = price * this.multiplier;   // 债券类 ×100
+    return otcformat.trading.umprice(price);
+}
+```
+
+---
+
+## 五、互换事件的生成路径与价格赋值
+
+互换 Tab 会按时间序列展示所有互换事件（EventType=互换/自动互换），手动与自动用**同一套渲染代码**，所以入库基准必须一致。
+
+### 手动互换（EventType=3）
+- 入口：`SwapDealService.SwapUnwind` / `InitIncome`
+- 价格赋值：`floatEvent.TradingAmountAvg = unwindPrice`（前端用户输入，已 ÷100）
+- **已赋值 `UnderlyingInstrumentType`**（来自 position）
+
+### 自动互换-分红型（EventType=4）⚠️ 重点
+- 入口：`SwapEodPositionService.DealDividends`（`PosiDividendSum != 0` 触发）
+- 价格赋值：`TradingAmountAvg = eodPosi.PosiNetPrice`（相对价，来自 eod 持仓）
+- **必须赋值 `UnderlyingInstrumentType` 和 `TradingAmountNetAvg`**（曾经遗漏导致 Bug）
+
+### 自动互换-利息端（EventType=4）
+- 入口：`DealAutoInterests` → `SaveAutoEodWithCloseInterestPosition`
+- `UnderlyingCode` 为空（利息腿），不出现在互换 Tab 浮动端
+
+---
+
+## 六、已修复的 Bug 与教训
+
+| Bug | 根因 | 修复提交 |
+|-----|------|---------|
+| 收益结算期末价缩放/显示错误 | `incomeSwapTrade.js` initDeal 合并冲突丢 ×multiplier | 已修 |
+| 收益结算期初净价显示 0 | `PosiNetNoFeePrice` 可空，为 0 时未回退 `PosiNetPrice` | 已修 |
+| 收益结算期末价不可编辑/无刷新图标 | `ab09cbc9` 误删输入框与方法 | 已修 |
+| **分红型自动互换显示未 ×100** | `DealDividends` 漏赋 `UnderlyingInstrumentType` | 已修（d9c5ce4c）|
+| **分红型自动互换期初净价显示 0** | `DealDividends` 漏赋 `TradingAmountNetAvg` | 已修（d9c5ce4c）|
+
+### 教训
+
+1. **生成 `swap_flow_event` 时必须赋全字段**，尤其是 `UnderlyingInstrumentType`——它是展示层判断债券/非债券（决定 ×100）的关键，遗漏会导致显示数量级错误。
+2. **手动互换与自动互换共用同一套展示代码**，入库基准（相对价）必须保持一致。
+3. **字段命名误导**：`TradingAmountNetAvg` 名字像"期末"，但收益结算初始化时装的是期初净价，改代码时务必核对实际数据流向。
+4. **可空字段要兜底**：`PosiNetNoFeePrice`、`TradingAmountNetAvg` 可空，展示时为 0/空要有回退值。
+
+---
+
+## 七、历史脏数据说明
+
+排查过程中发现，测试环境里同一笔手动互换的 `swap_flow_event` 可能存在多条记录，`TradingAmountAvg` 取值不一致（有的相对价如 1.0011，有的被 ÷100 如 0.010011），成交金额相应相差 100 倍。这是早期代码版本更迭残留的脏数据。
+
+判断脏数据的依据：成交金额 `TradingAmount = TradingAmountAvg × Quantity × ContractSize`（后端 `SwapDealService:1103` 计算）。若同一交易的两条互换记录成交金额相差正好 100 倍，则其中一条的 `TradingAmountAvg` 被多 ÷100。
+
+这类历史数据问题用 SQL 单独修复，**不应在代码里迁就脏数据而保留错误的逻辑**。排查与修复 SQL 见文末附录。
+
+---
+
+## 附录 A：排查工具箱 SQL
+
+> 以下 SQL 是 2026-06 价格显示 Bug 排查过程中验证有效的查询，数据库为 MySQL，库名 `glms_yltrs_ylcms`（ylcms 连接）。后续遇到类似"显示数量级不对"问题可直接复用。
+
+### A.1 查互换交易期初持仓的 4 个价格字段（确认入库基准）
+
+```sql
+SELECT
+    t.TradeNumber           AS trade_no,
+    t.StructureType         AS 结构类型,
+    sp.UnderlyingCode       AS 标的代码,
+    sp.PosiGrossPrice       AS 期初全价,
+    sp.PosiNetPrice         AS 期初净价,
+    sp.PosiNetNoFeePrice    AS 期初净价不含费,
+    sp.PosiNetFeePrice      AS 期初净价含费
+FROM trade t
+JOIN swap_position sp ON sp.SwapTradeId = t.id
+                      AND sp.IsInitial = 1
+                      AND sp.UnderlyingCode IS NOT NULL   -- 过滤利息腿/预付金腿
+WHERE t.TradeType = '收益互换'
+  AND t.StructureType IN ('普通债券类收益互换', '普通收益互换')
+  AND t.ValidState = 'valid'
+ORDER BY t.id DESC
+LIMIT 20;
+```
+
+### A.2 查互换/自动互换事件入库值（区分手动/自动、用成交金额反推正确基准）
+
+⚠️ `swap_flow_event` 表的 `PosiGrossPrice`/`PosiNetPrice` 是 `[NotMapped]`，**数据库查不到这两列**；只能查真正入库的 `TradingAmountAvg`、`TradingAmountNetAvg`、`TradingAmount`。
+
+```sql
+SELECT
+    t.TradeNumber          AS trade_no,
+    fe.id                  AS 事件ID,
+    fe.EventType           AS 事件类型,
+    CASE fe.EventType WHEN 3 THEN '手动互换' WHEN 4 THEN '自动互换' END AS 类型,
+    fe.EventReason         AS 事件原因,
+    fe.EventDate           AS 业务日期,
+    fe.UnderlyingCode      AS 标的,
+    fe.PayDirection        AS 收支方向,
+    fe.PositionType        AS 多空方向,
+    fe.UnderlyingInstrumentType AS 标的类型_判断债券用,
+    fe.TradingAmountAvg    AS 期末全价_入库,
+    fe.TradingAmountNetAvg AS 期末净价_入库,
+    fe.TradingAmount       AS 成交金额,
+    fe.DividendIn          AS 分红金额
+FROM trade t
+JOIN swap_flow_event fe ON fe.SwapTradeId = t.id
+WHERE t.id IN (/*填trade id*/)
+  AND t.ValidState = 'valid'
+  AND fe.EventType IN (3, 4)
+  AND fe.UnderlyingCode IS NOT NULL   -- 只要浮动端事件,排除利息腿
+ORDER BY t.id, fe.EventDate DESC, fe.id DESC
+LIMIT 30;
+```
+
+**判断要点**：
+- `UnderlyingInstrumentType` 为空 → 该事件的展示会走"非债券分支（不×100）"，债券标的显示会错（这就是自动互换的 Bug 根因）。
+- 同一交易同一腿出现 `TradingAmountAvg` 相差 100 倍的两条记录 → 其中一条是被多 ÷100 的脏数据。
+
+### A.3 查分红型自动互换的数据源（eod_swap_position，确认 PosiDividendSum 触发条件）
+
+`PosiDividendSum != 0` 时触发 `DealDividends` 生成自动互换事件。注意测试数据可能为 0 查不到，需去掉该条件排查。
+
+```sql
+SELECT
+    esp.SwapTradeId        AS trade_id,
+    esp.ValueDate          AS 持仓日期,
+    esp.UnderlyingCode     AS 标的代码,
+    esp.UnderlyingInstrumentType AS 标的类型,
+    esp.PosiDividendSum    AS 浮动端未实现分红_触发条件,
+    esp.TdPosiDividend     AS 当日浮动端分红,
+    esp.PosiNetPrice       AS 持仓净价_自动互换TradingAmountAvg来源,
+    esp.PosiGrossPrice     AS 持仓全价,
+    esp.PosiNetNoFeePrice  AS 持仓净价不含费_期初净价来源
+FROM eod_swap_position esp
+WHERE esp.SwapTradeId IN (/*填trade id*/)
+ORDER BY esp.ValueDate DESC
+LIMIT 20;
+```
+
+### A.4 查中债估值数据源（确认录入时默认读取的价格）
+
+簿记交易时标的默认价格来自 `china_bond_valuation`（中债估值）表。⚠️ **该表的字段命名与业务常用名差异很大**，特别注意：债券代码列是 `bond_id`（不是 UnderlyingCode），价格列是 `dirty_price_close`（日终估值全价）、`net_price`（估价净值）、`yield`（收益率%）、`vobp`（基点价值）。
+
+```sql
+SELECT
+    cbv.bond_id            AS 债券代码,
+    cbv.valuation_date     AS 估值日期,
+    cbv.dirty_price_close  AS 日终估值全价,   -- 录入默认读取的"全价"来源
+    cbv.net_price          AS 估价净值,
+    cbv.yield              AS 估价收益率_pct,
+    cbv.vobp               AS 估价基点价值,   -- DV01 计算用此字段
+    cbv.acc_rint_close     AS 日终应计利息,
+    cbv.credibility        AS 可信度          -- GetBondPrice 按可信度降序取最新
+FROM china_bond_valuation cbv
+WHERE cbv.bond_id = '180205.IB'
+ORDER BY cbv.credibility DESC, cbv.valuation_date DESC
+LIMIT 10;
+```
+
+> 后端 `EodPriceQueryService.GetBondPrice` 取数逻辑：按 `bond_id` 匹配，`valuation_date <= 指定日`，按 `credibility` 降序、`valuation_date` 降序取第一条。返回的 `ClosePrice = dirty_price_close × bondPriceMultiple`（默认乘数通常为 1）。测试环境可能被维护成离谱值（如全价 1999）。
+
+### A.5 历史脏数据修复（手动互换被多 ÷100 的记录）
+
+⚠️ **执行前务必先用 A.2 核对，并备份**。以下仅作为模板，需根据实际范围调整 WHERE：
+
+```sql
+-- 备份
+CREATE TABLE swap_flow_event_bak_yyyymmdd AS
+SELECT * FROM swap_flow_event WHERE /*同下方WHERE条件*/;
+
+-- 修复: 被多÷100的TradingAmountAvg ×100还原, 成交金额同步×100
+UPDATE swap_flow_event fe
+JOIN trade t ON t.id = fe.SwapTradeId
+SET fe.TradingAmountAvg = fe.TradingAmountAvg * 100,
+    fe.TradingAmount     = fe.TradingAmount * 100
+WHERE t.StructureType = '普通债券类收益互换'
+  AND fe.EventType = 3                 -- 手动互换
+  AND fe.UnderlyingCode IS NOT NULL
+  AND fe.TradingAmountAvg > 0
+  AND fe.TradingAmountAvg < 0.5;       -- 相对价合理范围判断(债券相对价通常0.5~2)
+```
+
+---
+
+## 附录 B：字段命名与数据流向速查
+
+容易混淆的字段对应关系（排查时务必核对实际数据流向，不要被字段名误导）：
+
+| 界面列（表头） | 取值字段 | 字段所在表 | 实际数据来源 | 备注 |
+|---|---|---|---|---|
+| 期初标的交割全价% | `PosiGrossPrice` | swap_position（入库）/ swap_flow_event（[NotMapped]运行时拷贝） | `swap_position.PosiGrossPrice` | 相对价，展示×100 |
+| 期初标的交割净价% | `TradingAmountNetAvg` | swap_flow_event（入库） | `swap_position.PosiNetNoFeePrice`（收益结算初始化时） | **字段名像期末，实装期初值**；可空需兜底 |
+| 期末标的交割全价% | `TradingAmountAvg` | swap_flow_event（入库） | 手动互换=用户输入；自动互换=`eod.PosiNetPrice` | 相对价，展示×100 |
+| 标的类型判断 | `UnderlyingInstrumentType` | swap_flow_event（入库） | 生成事件时赋值 | **展示层判断债券(×100)的关键，必须赋值** |
+| 成交金额 | `TradingAmount` | swap_flow_event（入库） | `TradingAmountAvg × Quantity × ContractSize` | 反推正确基准的依据 |
+
+**关键提醒**：`swap_flow_event.PosiGrossPrice` 和 `PosiNetPrice` 是 `[NotMapped]`，数据库**没有这两列**，查库会报 `Unknown column`。它们只在运行时从 `swap_position` 拷贝过来用于展示。

+# 互换价格字段命名规范决策
+
+> 本文档是**命名规范的决策与论证**，回答"应该叫什么、为什么这么叫"。
+> 现状梳理（字段流向、存储显示规则）见姊妹文档 [互换交易价格字段存储与显示规范.md](互换交易价格字段存储与显示规范.md)。
+> 适用范围：互换业务（收益互换）涉及的价格、方向、时点字段。期权/远期业务字段不在本文档范围。
+
+---
+
+## 一、为什么命名必须先定下来
+
+现状是**同一概念多套名字、名字与含义颠倒**，已经反复造成 Bug。三条最严重的证据：
+
+1. **`PosiNetPrice` 名为"Net"，实为"含费全价"**。真正的净价是 `PosiNetNoFeePrice`。连现状文档（《互换交易价格字段存储与显示规范》）都把它误标成"期初净价"——文档作者都被字段名骗了。
+2. **两套并行命名无对应关系**：持仓表 `PosiNetPrice` ↔ 流水表 `TradingAmountFeeAvg`，持仓表 `PosiGrossPrice` ↔ 流水表 `TradingAmountAvg`，名字里没有一处对得上。
+3. **前端同一中文标签绑不同字段**：`成交净价` 一处绑 `TradingAmountNet`，另一处绑 `TradingAmountNetAvg`；`期初标的价格` 录入页绑 `PosiGrossPrice`，平仓明细页绑 `PosiNetPrice`。
+
+命名不定下来，后续每个改动都要反复核对数据流向，且极易引入新 Bug。本文档的目的是**把每个维度的命名一次性钉死，给出对比理由**。
+
+---
+
+## 二、三个维度的决策
+
+互换价格有三个正交维度，必须分别命名：
+
+| 维度 | 取值 | 现状混乱 |
+|---|---|---|
+| **A. 价格种类** | 全价 / 净价 | Net/Gross 颠倒；Posi vs TradingAmount 两套 |
+| **B. 是否含交易费** | 含费 / 不含费 | Fee 标记位置在两套体系里相反 |
+| **C. 时点** | 期初 / 期末 / 盯市 | Start/Begin/End/Initial/Final/Spot/Open 散布，无统一规则 |
+
+外加一个**方向维度**（收取方/支付方），目前用中文枚举，trade_swap 老表用 Get/Pay。
+
+下面逐项决策。
+
+---
+
+## 三、维度 A：价格种类 —— 采用 Clean / Dirty
+
+### 候选对比
+
+| 方案 | 优点 | 缺点 | 评价 |
+|---|---|---|---|
+| **`Clean / Dirty`** | 债券行业标准术语；歧义最小；与中债估值表 `dirty_price_close`/`net_price`、量化库常见命名一致 | 非 OTDer 可能需要学习成本 | **✅ 推荐** |
+| `Net / Gross`（现状持仓表） | 简短 | **本项目已颠倒**（PosiNetPrice 是含费全价）；Net/Gross 在金融里本身就有"净值/毛额"歧义，不专指债券净价全价 | ❌ 已证明不可行 |
+| `Clean / Full` | Full 含义尚可 | 不如 Dirty 标准；中债表用 dirty，不统一 | △ |
+| `净价 / 全价`（中文直译） | 业务人员熟悉 | C# 字段用中文不合规；与现有英文体系混搭更乱 | ❌ |
+
+### 决策
+
+**全价用 `Dirty`，净价用 `Clean`。**
+
+理由：
+1. **行业术语，零歧义**。Clean/Dirty 是债券领域全世界通用的无歧义术语（clean price = 不含应计利息，dirty price = 含应计利息）。
+2. **与数据源一致**。录入默认价格来源 `china_bond_valuation` 表用的就是 `dirty_price_close`（日终估值全价）和 `net_price`（估价净值）。字段命名与数据源对齐，减少心智负担。
+3. **现状 Net/Gross 已被证明失败**。它在本项目里语义颠倒，且 Net 在不同字段里含义不同（PosiNetPrice 的 Net = 含费，PosiNetNoFeePrice 的 Net = 净价），是混乱根源，必须废弃。
+
+### 与"费"维度组合后的完整 4 象限见第五节。
+
+---
+
+## 四、维度 B：费用 —— 采用 Fee / NoFee
+
+### 先澄清："费"是什么
+
+**"费" = 交易费用 / 佣金（TradingFee）**，由 `TradeFeeHelper.CalcPriceWithFee(price, fee, qty)` 计算：`含费价 = 不含费价 + 单位佣金`。它**不是**应计利息（应计利息体现在 Clean/Dirty 维度），也**不是**利息腿费用。
+
+### 候选对比
+
+| 方案 | 优点 | 缺点 | 评价 |
+|---|---|---|---|
+| **`Fee / NoFee`（后缀）** | 现状已在用（PosiNetNoFeePrice/TradingAmountFeeAvg）；直白 | — | **✅ 推荐**（沿用现有约定，零迁移成本） |
+| `Gross / Net`（用 Net 表示含费） | — | 与维度 A 的 Clean/Dirty 严重冲突，两套词打架 | ❌ |
+| `WithFee / WithoutFee` | 更明确 | 太长；后缀冗余 | △ |
+| `PreFee / PostFee` | 金融衍生品常见 | 偏衍生品语境，互换收益端用着别扭 | △ |
+
+### 决策
+
+**含费用 `Fee` 后缀，不含费用 `NoFee` 后缀。**
+
+理由：现状流水表已经是这套（`TradingAmountAvg` 不含费 / `TradingAmountFeeAvg` 含费 / `TradingAmountNetAvg` 净价不含费 / `TradingAmountNetFeeAvg` 净价含费），**这个约定本身没问题**，问题是持仓表用了另一套颠倒的 Posi 命名。统一到 Fee/NoFee 即可。
+
+---
+
+## 五、维度 A+B 组合：价格 4 象限最终命名
+
+### 决策表
+
+| 业务含义 | **规范命名** | 现状持仓表 | 现状流水表 |
+|---|---|---|---|
+| 全价 · 不含费 | `XxxDirtyPrice` | `PosiGrossPrice` | `TradingAmountAvg` |
+| 全价 · 含费 | `XxxDirtyFeePrice` | `PosiNetPrice` ⚠️ | `TradingAmountFeeAvg` |
+| 净价 · 不含费 | `XxxCleanPrice` | `PosiNetNoFeePrice` | `TradingAmountNetAvg` |
+| 净价 · 含费 | `XxxCleanFeePrice` | `PosiNetFeePrice` | `TradingAmountNetFeeAvg` |
+
+其中 `Xxx` 是时点前缀（见第六节）。
+
+### 命名规则一句话
+
+> **`{时点}{Dirty|Clean}{Fee|}{Price}`** —— Dirty/Clean 选价格种类，Fee 出现表示含费、不出现表示不含费。
+
+例：`EntryDirtyPrice`（期初全价不含费）、`EntryDirtyFeePrice`（期初全价含费）、`ExitCleanPrice`（期末净价不含费）。
+
+---
+
+## 六、维度 C：时点 —— 采用 Entry / Exit（+ Market）
+
+这是你重点要求对比的部分。先看现状，再逐词对比。
+
+### 现状：时点词散布（统计自实体字段）
+
+| 现状词 | 出现次数（实体字段） | 用在什么字段 |
+|---|---|---|
+| `Start` | 36 | StartDate（起始日） |
+| `Spot` | 28+4 | SpotPrice（期初价，期权/远期）、GetSpotPrice/PaySpotPrice（trade_swap） |
+| `Open` | 3 | OpenPrice、OpenTradePrice（开仓价） |
+| `Init/Initial` | 4 | InitYtm、InitialSpotPrice（[NotMapped]） |
+| `Final` | 10 | FinalPrice（期末价）、GetFinalPrice/PayFinalPrice |
+| `End` | 12 | EndDate（结束日） |
+| `Close` | 21 | ClosePrice（收盘价，行情侧） |
+| `Maturity` | 14 | MaturityDate（到期日） |
+| `Entry/Exit` | **0** | 未使用 |
+
+**现状问题**：表达"期初价"用了 `Spot`、`Open`、`Init`、`Initial` 四种；表达"期末价"用了 `Final`、`End`、`Close` 三种；且 `Close` 还和"行情收盘价"语义重叠。
+
+### 候选词逐个对比
+
+#### 期初价（开仓成本价）候选
+
+| 方案 | 含义直觉 | 优点 | 缺点 | 评价 |
+|---|---|---|---|---|
+| **`Entry`** | 入场/建仓 | 交易术语，明确"进入持仓那一刻"；与 `Exit` 对称；**不与现有任何日期/价格词冲突** | 全新词，需迁移 | **✅ 推荐** |
+| `Start` | 开始 | 与 `StartDate`（起始日）一致，延续性最好 | **与日期混淆**：`StartPrice` 容易被误读成"起始日当天的价格"而非"建仓成本价"；价格 vs 日期语义纠缠 | △ |
+| `Begin` | 开始 | 同 Start | 同 Start；且与 Start 二选一造成二次混乱（现已有 Start，再加 Begin 是雪上加霜） | ❌ |
+| `Initial` / `Init` | 初始 | 语义尚可 | `Init` 是缩写不规整；现状 `InitYtm` 已用，但 `InitialPrice` 太长；**Init/Initial 两种并存**（现状就有 `InitYtm` 和 `InitialSpotPrice`）本身就是混乱证据 | ❌ |
+| `Spot` | 即期 | 现状 trade_swap 在用 | **语义错误**：Spot 在金融里指"即期（spot vs forward）"，不是"期初"；互换里强行用 Spot 表示期初是误用；且与"即期价格"概念冲突 | ❌ |
+| `Open` | 开仓 | 有"开仓"意味 | `OpenPrice` 在期权语境指"开盘价"（open=开盘 vs close=收盘），互换用 Open 会与行情术语打架 | ❌ |
+
+#### 期末价（平仓/到期价）候选
+
+| 方案 | 含义直觉 | 优点 | 缺点 | 评价 |
+|---|---|---|---|---|
+| **`Exit`** | 出场/了结 | 与 Entry 对称；明确"退出持仓那一刻"；**不与 Close/Maturity 冲突** | 全新词，需迁移 | **✅ 推荐** |
+| `Final` | 最终 | 现状在用（FinalPrice） | `Final` 在期权语境常指"到期(final/expiration)"，与互换"平仓了结"语义有偏差；且 Final 给人"永远结束"的感觉，但互换可能多次部分平仓（每次都是 Exit） | △ |
+| `End` | 结束 | 简短 | 与 `EndDate`（结束日）混淆，同 Start 的问题 | ❌ |
+| `Close` | 收盘 | 行情侧在用（ClosePrice） | **语义已被占用**：Close = 收盘行情价；互换平仓价用 Close 会和"每日盯市收盘价"混淆。这是现状混乱之一 | ❌ |
+| `Maturity` | 到期 | 债券标准术语 | 只适用于"持有到期"，不适用于"提前平仓"；互换平仓≠到期 | ❌（仅 MaturityDate 用于到期日） |
+
+### 决策
+
+**期初用 `Entry`，期末用 `Exit`，每日盯市用 `Market`。**
+
+### 为什么是 Entry/Exit 而不是其他 —— 三条核心理由
+
+**理由 1：Entry/Exit 是唯一一组"互相对称、且不与现有词冲突"的方案。**
+
+| 对称组 | 冲突情况 |
+|---|---|
+| **Entry / Exit** | ✅ 零冲突，现有代码 0 处使用 |
+| Start / End | ❌ 与 StartDate/EndDate 日期字段冲突 |
+| Open / Close | ❌ 与行情开盘价/收盘价冲突 |
+| Initial / Final | △ Initial 太长，Final 偏"到期"语义 |
+| Begin / End | ❌ 与 Start 重复造词 |
+
+互换价格的核心心智模型是"**Entry（建仓成本）vs Exit（了结价格）**"——盈亏 = Exit − Entry。Entry/Exit 直接表达这个对偶关系，其他词都带着别的语义包袱。
+
+**理由 2：互换"多次部分平仓"语义下，Entry/Exit 比 Start/End/Final 更准确。**
+
+互换持仓期间可以有多次部分平仓（每次部分平仓都是一次 Exit），不是"一次性 Start→End"。`Final`（最终）暗示"只有最后一次"，`Start`/`End` 暗示"单一起止点"，都不符合"多次 Exit"的现实。`Exit` 天然支持"多次出场"语义（每次平仓 = 一次 Exit）。
+
+**理由 3：与"盯市价"清晰分层。**
+
+| 时点 | 命名 | 含义 |
+|---|---|---|
+| 建仓时 | `Entry*` | 成本价（固定） |
+| 平仓时 | `Exit*` | 了结成交价（每次平仓一个） |
+| 持仓期间每日 | `Market*` | 盯市价（随行情变动） |
+
+三者职责清晰：Entry 是成本基线，Exit 是实现盈亏的时点，Market 是浮动盈亏的基准。现状 `UnderlyingPrice`（盯市价）改为 `MarketDirtyPrice` 后，与 Entry/Exit 形成 `Entry / Market / Exit` 完整时点链。
+
+### 收益率字段同理
+
+| 含义 | 规范命名 | 现状 |
+|---|---|---|
+| 期初 YTM | `EntryYtm` | InitYtm |
+| 平仓 YTM | `ExitYtm` | ytm / Ytm |
+
+---
+
+## 七、维度 D：方向 —— 收取/支付方的命名
+
+### 现状
+
+| 位置 | 现状命名 | 问题 |
+|---|---|---|
+| `SwapDirectionEnum`（V2 在用） | `收取 / 支付`（中文） | C# 字段用中文不合规；与英文代码混排突兀 |
+| `trade_swap`（老表，已弃用互换主流程） | `Get* / Pay*`（如 GetSpotPrice/PaySpotPrice） | Get 语义弱，不像金融术语；你已指出这是老互换遗留 |
+| `PositionTypeFlag`（多空） | `Long / Short` | ✅ 这个没问题，标准术语 |
+| 业务文档/前端 | "收取方/支付方"、"固定端/浮动端" | 中文展示 OK |
+
+### 候选对比（英文方向词）
+
+| 方案 | 优点 | 缺点 | 评价 |
+|---|---|---|---|
+| **`Rcv / Pay`** | 金融工程标准（IRS 收付固定方叫 Receive/Pay）；FINCAD/Bloomberg/量化库通用；3字母缩写简洁 | Rcv 需要新人熟悉"是 receive 缩写" | **✅ 推荐** |
+| `Receive / Pay` | 不缩写，更明确 | Receive 较长，字段名 `ReceiveDirtyPrice` 偏长 | △ |
+| `Get / Pay`（现状老表） | 现状 | Get 不是金融术语，语义弱（"获得"太泛）；与 Pay 不对称（Pay 是金融词，Get 是口语） | ❌ |
+| `Long / Short` | 标准术语 | **语义不同**：Long/Short 是多头/空头（PositionType），不是收取/支付方（SwapDirection）；互换里收取方可能是空头。**两者不能混用** | ❌（维度不同） |
+| `Buy / Sell` | 通用 | 互换不是买卖关系，是交换现金流；Buy/Sell 易误导 | ❌ |
+
+### 决策
+
+**英文方向词用 `Rcv / Pay`，仅用于代码字段名（如 `RcvEntryDirtyPrice`）；枚举值和前端展示保持中文"收取/支付"。**
+
+理由：
+1. **金融标准**。利率互换（IRS）行业里固定方/浮动方标准叫法就是 Receive fixed / Pay fixed，FINCAD、Bloomberg、主流量化库都用 Rcv/Pay。
+2. **纠正老表 Get 的错误**。trade_swap 的 `Get/Pay` 里 Get 不是金融词，是早期随手起的，正好借命名规范统一为 Rcv/Pay。
+3. **不与 Long/Short 冲突**。Rcv/Pay 是 SwapDirection（收取/支付哪一端现金流），Long/Short 是 PositionType（多空），两个维度独立，不能互相替代。
+4. **中文枚举保留**。`SwapDirectionEnum.收取/支付` 已被业务文档、前端、监管报表广泛使用，强行改英文枚举值成本高且无收益。只在新英文字段名里用 Rcv/Pay。
+
+> 注：当前 V2 互换主流程（swap_position/eod_swap_position）已经不按"收取/支付腿"存价格（价格存在不分腿的持仓记录里，方向用 `PosiDirection` 字段标记），所以 `Rcv/Pay` 前缀**只在需要显式区分双腿的场景**（如 trade_swap 录入、双边互换）使用，不是所有字段都加。
+
+---
+
+## 八、最终命名总表（一锤定音）
+
+### 8.1 价格 4 象限（含时点前缀）
+
+| 业务含义 | 规范命名 | 现状（持仓/流水） |
+|---|---|---|
+| 期初全价·不含费 | `EntryDirtyPrice` | PosiGrossPrice / — |
+| 期初全价·含费 | `EntryDirtyFeePrice` | PosiNetPrice ⚠️ / — |
+| 期初净价·不含费 | `EntryCleanPrice` | PosiNetNoFeePrice / — |
+| 期初净价·含费 | `EntryCleanFeePrice` | PosiNetFeePrice / — |
+| 期末/平仓全价·不含费 | `ExitDirtyPrice` | — / TradingAmountAvg |
+| 期末/平仓全价·含费 | `ExitDirtyFeePrice` | — / TradingAmountFeeAvg |
+| 期末/平仓净价·不含费 | `ExitCleanPrice` | — / TradingAmountNetAvg |
+| 期末/平仓净价·含费 | `ExitCleanFeePrice` | — / TradingAmountNetFeeAvg |
+| 盯市全价 | `MarketDirtyPrice` | UnderlyingPrice |
+| 期初收益率 | `EntryYtm` | InitYtm |
+| 期末收益率 | `ExitYtm` | ytm |
+
+### 8.2 方向
+
+| 业务含义 | 代码字段名 | 枚举/展示值 |
+|---|---|---|
+| 收取方 | `Rcv*`（如需区分腿） | 收取（SwapDirectionEnum.收取） |
+| 支付方 | `Pay*`（如需区分腿） | 支付（SwapDirectionEnum.支付） |
+| 多头 | `Long`（PositionTypeFlag.Long） | 多头 |
+| 空头 | `Short`（PositionTypeFlag.Short） | 空头 |
+
+### 8.3 命名规则速记
+
+> **价格 = `{Entry|Exit|Market}{Dirty|Clean}{Fee|}Price`**
+> **方向 = `Rcv|Pay`（SwapDirection）与 `Long|Short`（PositionType）是两个独立维度，不混用**
+> **收益率 = `{Entry|Exit}Ytm`**
+
+---
+
+## 九、落地策略（渐进式，不一次性改）
+
+直接全局重命名风险极高（DB 列 + EF 实体 + ~15 服务类 + ~20 前端文件 + 交易确认书 + Excel 导入）。建议分阶段：
+
+| 阶段 | 动作 | 风险 | 产出 |
+|---|---|---|---|
+| **0. 文档定调（本文档）** | 命名规则钉死，团队达成共识 | 零 | 本文档 |
+| **1. 注释止血** | 在现状最混乱的字段（PosiNetPrice/PosiGrossPrice）加 `[Obsolete]` + XML 注释，写明真实含义与规范名 | 零 | 防止再被字段名误导 |
+| **2. 前端统一取值封装** | 新增 `swapPriceHelper.js`，把分散的 `item.PosiGrossPrice` 等收敛成 `getEntryDirtyPrice(item)`；先修"同标签绑不同字段"的混乱 | 低 | 前端混乱点消除 |
+| **3. 新代码强制规范** | 新增字段/新功能必须用规范命名；对外 API 新增 DTO 用规范名，内部旧字段靠 Mapper 转换 | 低 | 增量规范化 |
+| **4. 大重构（慎重）** | DB 列重命名 + EF 映射 + 全量替换，配合数据迁移。建议趁大版本升级做 | 高 | 彻底统一 |
+
+**阶段 1 最该立刻做**：给 `PosiNetPrice`（含费全价，非净价）和 `PosiGrossPrice`（不含费全价）加注释，因为连现状文档都被它们误导过。
+
+---
+
+## 附录：现状混乱全证据清单（决策依据）
+
+> 以下每条都有代码/DDL/前端文件佐证，是上述决策的事实基础。
+
+| # | 混乱点 | 关键证据位置 |
+|---|---|---|
+| 1 | PosiNetPrice 名为 Net 实为含费全价 | `SwapTradeService.cs:372-373` 赋值：PosiNetPrice←TradingAmountFeeAvg（含费均价） |
+| 2 | PosiGrossPrice 名为 Gross 实为不含费全价 | 同上：PosiGrossPrice←TradingAmountAvg（不含费均价） |
+| 3 | 同字段两表 DDL 注释矛盾 | PosiNetPrice：swap_position 注释"持仓净价"，eod_swap_position 注释"期初标的价格" |
+| 4 | 持仓表/流水表两套命名无对应 | Posi*（Net/Gross）vs TradingAmount*（Avg/FeeAvg），名字对不上 |
+| 5 | 前端同标签绑不同字段 | `成交净价` 绑 TradingAmountNet(303) 也绑 TradingAmountNetAvg(508)，见 SwapflowList.js |

+# 互换分红损益：字段语义与重复计算分析
+
+> 本文档分析互换（收益互换）"分红/付息损益"核算链路中存在的字段语义混乱与分红重复计算问题。
+> 用真实交易数据佐证，供团队对齐字段语义、确定修复方案。
+> 成文于 2026-06，排查范围覆盖 `f9d8a256`（山证基线）至 `1c9b28ff`（最新）。
+
+---
+
+## 一、问题概述
+
+互换的"已实现盈亏"在多个代码路径下**会把同一笔分红计算恰好 2 次**，导致已实现盈亏虚高（分红翻倍）。
+
+根本原因：**`MarkClosePnl`（盯市盈亏）字段把"价差盈亏"和"分红"揉在了一起**，而分红又有独立的字段 `DividendIn`，导致同一笔分红在两个字段里各存了一份，汇总时被重复累加。
+
+> 经过逐行确认代码路径 + 真实数据验证，**确定**是 2 次（非 2~3 次）。证明见第三、四章。
+
+---
+
+## 二、字段分类：客观源头 vs 派生计算
+
+理解整块的关键是分清"客观源头"（不可改的事实）和"派生计算"（基于源头算出来的）。分三层：
+
+### 第一层：客观源头（事实，所有计算的基石）
+
+| 字段 | 所在表 | 来源 | 含义 | 示例值 |
+|------|--------|------|------|--------|
+| `payment_interest` | `bond_payment` | 外部付息公告 | 每张面值付息额（如每100元付3元）| 3 |
+| `PosiQuantity` | `swap_position` | 用户录入/中债估值 | 持仓数量 | 1000万 |
+| `PosiGrossPrice` | `swap_position` | 用户录入/中债估值 | 期初全价（相对价） | 1.00 |
+| `TradingAmountAvg` | `swap_flow_event` | 用户互换/平仓时输入 | 期末全价（相对价） | 1.00 |
+
+> 这些是"真实发生的事"，不随计算方式改变。
+
+### `totalInterest` 的来源（payment_interest → totalInterest → DividendIn 链路）
+
+`totalInterest` **不是** `payment_interest` 本身，而是经过换算的"每张分红率（小数）"。链路：
+
+```
+payment_interest (bond_payment, 每张付息额, 如 3)
+   │ GetBondPaymentService 在区间内求和
+   ▼
+Σ payment_interest (如 3+3+3=9)
+   │ × 0.01  (从"每100元"转成"小数比率")
+   ▼
+0.09
+   │ ÷ (1+税) × (1-税)  (增值税调整, 与 EOD 口径一致)
+   ▼
+totalInterest ≈ 0.077  (每张面值的分红率, 小数)
+   │ 前端 getDivindIn: PosiQuantity × totalInterest × 方向
+   ▼
+DividendIn = 1000万 × 0.077 × 方向 = -770000  (本次互换的分红金额)
+```
+
+代码位置：后端 `BondPaymentController.GetBondPayMentInterest`（`BondPaymentController.cs:91-100`），前端 `getDivindIn`（`incomeSwapTrade.js:197` / `unwindSwapTrade.js:286`）。
+
+### 第二层：一次计算（基于源头直接算）
+
+| 字段/中间值 | 所在表 | 算法 | 示例 |
+|------------|--------|------|------|
+| `DividendIn` | `swap_flow_event` | `PosiQuantity × totalInterest × 方向`（后端算每张率，前端算金额）| -9148.25 |
+| 价差盈亏（临时值） | 无独立字段 | `CloseNotionalValue × (期末价 - 期初价) × 方向` | 0（期末=期初时）|
+| `TradingFee` | `swap_flow_event` | 用户填的费用 | 0 |
+
+### 第三层：入库字段（⚠️ 问题所在）
+
+| 字段 | 所在表 | 算法 | ⚠️ 问题 |
+|------|--------|------|---------|
+| **`MarkClosePnl`** | `swap_flow_event` | `价差盈亏 + 交易费 + DividendIn` | **把分红揉进来了！** |
+| `DividendIn` | `swap_flow_event` | 直接存第二层的值 | 和上面 MarkClosePnl 里的分红是**同一笔** |
+
+**核心矛盾**：同一笔分红（如 -9148.25）同时存在 `MarkClosePnl` 和 `DividendIn` 两个字段里。
+
+---
+
+## 三、MarkClosePnl 含分红：四个场景对照表（代码 + 数据佐证）
+
+`MarkClosePnl` 在四个场景下的计算来源不同，但**全部含分红**：
+
+| 场景 | EventType | MarkClosePnl 计算位置 | 算法 | 含分红 |
+|------|-----------|---------------------|------|--------|
+| 手动互换 | 3 | 前端 `calcFloatClosePnl:140`（后端 `SwapIncome` 直接存）| `价差 + 费 + DividendIn` | **含** |
+| 手动平仓 | 2 | 前端 `calcFloatClosePnl`（后端 `SwapUnwind` 直接存）| `价差 + 费 + DividendIn` | **含** |
+| 自动互换(分红型) | 4 | 后端 `DealDividends:463` | `= PosiDividendSum`（分红本身）| **含**（就是分红本身）|
+| 自动全平仓 | 2 | 后端 `AuotoSwapUnwind:1102`（`SwapDealService` 类）| `价差 + 费 + DividendIn` | **含** |
+
+> 注意：后端 `SwapDealService:1102` 在 `AuotoSwapUnwind` 方法内，仅被 `SwapTradeAutoService` 调用（自动全平仓，如到期自动平仓）。**手动互换/平仓的 MarkClosePnl 由前端算好后传入，后端直接存库不重算。**
+
+### 真实数据佐证（2026-06 查询实测）
+
+查询 swap_flow_event，对有分红（DividendIn!=0）的事件看 `MarkClosePnl`、`DividendIn`、`价差（期末-期初）`：
+
+**A组：MarkClosePnl == DividendIn（差值=0，纯分红，无价差）**
+
+| trade | EventType | 标的 | MarkClosePnl | DividendIn | 差值 | 价差(期末-期初) |
+|-------|-----------|------|--------------|------------|------|----------------|
+| 1854 | 4(自动互换) | 180205.IB | -18.95 | -18.95 | **0** | **0** |
+| 1854 | 3(互换) | 180205.IB | 18.00 | 18.00 | **0** | **0** |
+| 1868 | 3(互换) | 210210.IB | 103.346 | 103.346 | **0** | **0** |
+| 1877 | 3(互换) | 210210.IB | -1033.46 | -1033.46 | **0** | **0** |
+| 1885 | 3(互换) | 180205.IB | -9148.25 | -9148.25 | **0** | **0** |
+| 1891 | 4(自动互换) | 180205.IB | -9.51 | -9.51 | **0** | **0** |
+
+**结论**：当价差=0（期末价=期初价）时，`MarkClosePnl` 完全等于 `DividendIn`。这证明 `MarkClosePnl = 价差(0) + 费(0) + 分红 = 分红`，**MarkClosePnl 含分红，铁证成立**。自动互换（EventType=4）同样成立。
+
+> B组（差值≠0，如 1891-3互换 MarkClosePnl=395594.949）的差值是"价差+费"成分，但这些是历史脏数据（期末价被多除100导致价差异常），不影响"MarkClosePnl 含分红"的结论——只是这部分价差也是脏的。
+
+---
+
+## 四、重复次数：确定 2 次（非 2~3 次）
+
+### 数据流图（以 trade 1885 纯分红互换为例，分红 = -9148.25）
+
+```
+【客观源头】
+  PosiQuantity = 100万, totalInterest = 每张分红率
+  期末价 = 期初价 = 1.00 (价差=0)
+        │
+        ▼
+【第二层计算】
+  DividendIn = 100万 × totalInterest × 方向 = -9148.25
+  价差盈亏 = 0
+  交易费 = 0
+        │
+        ▼
+【第三层入库 swap_flow_event】 ⚠️ 问题在这里
+  ┌──────────────────────────────────────────────┐
+  │ MarkClosePnl = 价差(0) + 费(0) + 分红(-9148.25) │ ◄── 分红第①次存入
+  │              = -9148.25                        │
+  │ DividendIn   = -9148.25                       │ ◄── 分红第②次存入(同一笔!)
+  └──────────────────────────────────────────────┘
+        │ 日终汇总
+        ▼
+【eod_swap_position】 (实测确认)
+  TdCloseMtmPnl   = Σ MarkClosePnl  = -9148.25  (含分红)
+  TdCloseDividend = Σ DividendIn    = -9148.25  (分红)
+        │
+        ▼
+【算 RealizedPnl 已实现盈亏】 ⚠️⚠️ 重复累加
+```
+
+### 各层级重复次数（确定 2 次）
+
+3 处代码分属**两个不同层级**，每个层级各自独立计算，但**每个层级分红都是 2 次**。不是叠加成 3 次。
+
+| 聚合对象 | 代码位置 | 公式 | 分红算几次 |
+|---------|---------|------|-----------|
+| 单持仓 `eod_swap_position.RealizedPnl` | `1490` + `1512` | `RealizedPnl = eod.RealizedPnl + TdCloseMtmPnl`；`if(PosiDividendSum==0) RealizedPnl += TdCloseDividend` | **2 次**（Mtm含1次 + Dividend加1次）|
+| 框架合约 `eod_swap.TdRealizedPnL`（当日） | `1866` | `TdRealizedPnL += TdCloseMtmPnl + TdCloseDividend` | **2 次**（Mtm + Dividend）|
+| 框架合约 `eod_swap.RealizedPnL`（累计） | `1869` | `RealizedPnL = Σ(RealizedMtmPnL + RealizedDividend + RealizedFee + ...)` | **2 次**（RealizedMtmPnL + RealizedDividend）|
+
+**为什么不是 3 次**：第1869行的 `eod_swap.RealizedPnL` **不读取**单持仓的 `eod_swap_position.RealizedPnl`，而是用 `RealizedMtmPnL + RealizedDividend` **独立重新聚合**。所以它与1490/1512行不是叠加关系——它们是**两个不同层级的对象**（`eod_swap` 是 `eod_swap_position` 的上层聚合），各自都把分红算了 2 次。
+
+```
+层级关系:
+  eod_swap_position (单持仓, 1490/1512算RealizedPnl)  ← 第1层,分红2次
+       │ 聚合
+       ▼
+  eod_swap (框架合约, 1866/1869重新聚合)              ← 第2层,分红2次(不读第1层的RealizedPnl)
+```
+
+**根本原因只有一个**：`MarkClosePnl`（→ `TdCloseMtmPnl`/`RealizedMtmPnL`）含分红，而 `DividendIn`（→ `TdCloseDividend`/`RealizedDividend`）又是同一笔分红。无论哪个层级，只要把"Mtm"和"Dividend"相加，分红就翻倍。
+
+---
+
+## 五、为什么会变成这样（演进过程，用 hash + 日期）
+
+分红核算经历了一长串反复修改，每次补丁都在加剧或修正重复：
+
+| 时间 | 提交 | 改动 | 效果 |
+|------|------|------|------|
+| 2024-05-09 | `f9d8a256` | 山证基线，MarkClosePnl 含分红 | 埋下根源 |
+| 2025-05-28 | `083848fb` | 审核流程重构，丢 eventType 分支 | 引入互换扣本金bug |
+| 2026-06-25 | `1aba5cca` | DealDividends 加 SwapPositionValue/RealizedPnl 调整 | 语句顺序错(EQD-6290) |
+| 2026-06-25 | `90b66922` | 修语句顺序 + 改全量重算口径 | 守恒修复✓ |
+| 2026-06-25 | `2140a97f` | 加 `RealizedPnl += TdCloseDividend` | **加剧重复!**（以为分红漏算，其实Mtm已含）|
+| 2026-06-26 | `1c9b28ff` | 互换审核不扣本金 | 修互换扣本金bug ✓ |
+
+---
+
+## 六、修复方向
+
+判断标准：**让每个字段语义单一、职责不重叠**。
+
+### 方向A（推荐，治本）：让 MarkClosePnl 不含分红
+
+让字段职责分离——Mtm 只管价差，Dividend 只管分红：
+
+| 改动点 | 改前 | 改后 |
+|--------|------|------|
+| 前端 `calcFloatClosePnl:140`（手动互换/平仓）| `MarkClosePnl = 价差 + 费 + DividendIn` | `MarkClosePnl = 价差 + 费`（去掉 DividendIn）|
+| 后端 `AuotoSwapUnwind:1102`（自动平仓）| `MarkClosePnl = 价差 + 费 + DividendIn` | 去掉 `+ DividendIn` |
+| 后端 `DealDividends:463`（自动互换）| `MarkClosePnl = PosiDividendSum` | `MarkClosePnl = 0`（自动互换无价差，分红走 DividendIn）|
+| `2140a97f` 新增（1512行）| `RealizedPnl += TdCloseDividend` | **保留**（此时 Mtm 不含分红，加 Dividend 才正确）|
+| 1490行 | `RealizedPnl = eod.RealizedPnl + TdCloseMtmPnl` | 保留（Mtm 现在是纯价差）|
+| 1866/1869行 | `TdCloseMtmPnl + TdCloseDividend` | 保留（现在 Mtm 不含分红，相加正确）|
+
+**效果**：
+```
+MarkClosePnl = 纯价差(0)          ← 只管价差
+DividendIn   = 分红(-9148.25)     ← 只管分红
+RealizedPnl  = TdCloseMtmPnl(0) + TdCloseDividend(-9148.25) = -9148.25  ← 各加1次,不重复 ✓
+```
+
+**风险**：要排查"前端盯市盈亏展示列"是否期望含分红（如果某处展示 MarkClosePnl 给用户看，去掉分红后显示会变）。需要回归测试前端展示。
+
+### 方向B（保守）：保留 MarkClosePnl 含分红，改汇总公式
+
+| 改动点 | 改法 |
+|--------|------|
+| 1866行 | `TdRealizedPnL += TdCloseMtmPnl`（去掉 `+ TdCloseDividend`，因为 Mtm 已含）|
+| 1869行 | `RealizedPnL = Σ(RealizedMtmPnL + RealizedFee + ...)`（去掉 `+ RealizedDividend`）|
+| `2140a97f`（1512行）| **撤销** `RealizedPnl += TdCloseDividend`（1490 的 Mtm 已含）|
+
+**风险**：`TdCloseDividend`/`RealizedDividend` 可能被分红明细报表单独展示，去掉后那部分变0。
+
+---
+
+## 七、建议
+
+1. **优先对齐"MarkClosePnl 该不该含分红"这个根本问题**。这是所有重复的根源。
+2. 达成共识后按**方向A**改（字段职责分离）。方向A改完后，`2140a97f` 这类补丁就不再需要，逻辑能稳定下来。
+3. 改完后用"守恒检验"验证：`ΔSwapPositionValue + ΔRealizedPnl == 0`（见附录 SQL）。
+4. **这块缺少自动化测试**（前端无测试、后端 Swap 单测只覆盖 EodPositionService）。建议补一个"分红守恒"后端单测兜底，避免反复打补丁。
+
+---
+
+## 附录A：验证 SQL
+
+### A.1 验证 MarkClosePnl 含分红（含价差佐证）
+
+```sql
+SELECT
+    fe.SwapTradeId  AS trade_id,
+    fe.EventType    AS 事件类型,   -- 2=平仓, 3=互换, 4=自动互换
+    fe.UnderlyingCode AS 标的,
+    fe.MarkClosePnl AS 盯市盈亏_入库,
+    fe.DividendIn   AS 分红_入库,
+    fe.MarkClosePnl - fe.DividendIn AS 差值_纯价差和费,
+    sp.PosiGrossPrice AS 期初全价,
+    fe.TradingAmountAvg AS 期末全价,
+    fe.TradingAmountAvg - sp.PosiGrossPrice AS 价差_期末减期初,
+    fe.TradingFee   AS 交易费
+FROM swap_flow_event fe
+JOIN swap_position sp ON sp.SwapTradeId = fe.SwapTradeId AND sp.IsInitial = 1 AND sp.UnderlyingCode = fe.UnderlyingCode
+WHERE fe.DividendIn != 0
+ORDER BY fe.SwapTradeId, fe.id DESC
+LIMIT 20;
+```
+**判断**：若某行 `差值=0` 且 `价差=0` → 证明无价差互换时 MarkClosePnl 完全等于分红。
+
+### A.2 验证分红互换守恒（修复后用）
+
+```sql
+SELECT
+    cur.SwapTradeId      AS trade_id,
+    cur.ValueDate        AS 当日,
+    cur.SwapPositionValue  AS 当日持仓价值,
+    pre.SwapPositionValue  AS 前日持仓价值,
+    cur.SwapPositionValue - pre.SwapPositionValue AS Δ持仓价值,
+    cur.RealizedPnl        AS 当日已实现盈亏,

+    (cur.SwapPositionValue - pre.SwapPositionValue) + (cur.RealizedPnl - pre.RealizedPnl) AS 守恒检验_应接近0,
+    cur.TdCloseDividend   AS 当日已实现分红_参考
+FROM eod_swap_position cur
+JOIN eod_swap_position pre
+  ON pre.SwapTradeId = cur.SwapTradeId AND pre.UnderlyingCode = cur.UnderlyingCode
+ AND pre.ValueDate < cur.ValueDate
+ AND pre.id = (SELECT MAX(id) FROM eod_swap_position
+               WHERE SwapTradeId = cur.SwapTradeId AND UnderlyingCode = cur.UnderlyingCode AND ValueDate < cur.ValueDate)
+WHERE cur.SwapTradeId IN (
+    SELECT DISTINCT fe.SwapTradeId FROM swap_flow_event fe
+    WHERE fe.EventType = 4 AND fe.DividendIn != 0 AND fe.UnderlyingCode IS NOT NULL
+)
+AND cur.UnderlyingCode IS NOT NULL
+ORDER BY cur.SwapTradeId DESC, cur.ValueDate DESC LIMIT 15;
+```
+**判断**：守恒检验列接近0 → 修复成功。

+
+## 附录D：测试策略
+
+### 现状
+- 后端有测试基础设施：`UnitTestProject/Modules/SwapModule/SwapEodPositionServiceIntegrationTest.cs`（MSTest，集成测试）
+- **但现有测试基础薄弱**：现有测试（如 `TestDealInterests_ViaSwapPositionCompose`）虽调用了真实业务代码 `service.SwapPositionCompose(...)`，但 catch 异常后 `Assert.IsTrue(true)` 就算通过，**没有对输出的 eod 持仓字段做任何断言**，属于"能跑不崩就算过"的烟雾测试，无法验证业务正确性。
+- 前端无测试框架（无 jest/mocha/playwright）
+
+### 教训：测试必须调用真实业务代码
+> 曾尝试写"构造字段对象自己断言"的纯逻辑测试（如 `TestDividendConservation_*`），但这类测试**自己造数据自己测**，不调用 `SwapEodPositionService` 的任何方法，是**无意义的伪测试**——业务代码写错也会通过。已删除。真正的测试必须：调用真实业务方法 → 查回输出字段 → 断言字段关系。
+
+### 后续测试方向
+- **参考 golden source 分支**：`glms/feature/refactor-swap-event-testable`（该分支有可复用的 Swap 事件测试数据构造，后续补分红守恒测试时以此为基础）
+- 真正有意义的守恒测试需要：
+  1. 用 golden source 的测试数据工厂构造一笔带分红的互换交易（`trade` + `swap_position` + `bond_payment` + `swap_flow_event`，多张表自洽）
+  2. 调用真实的 `SwapPositionCompose` 或 `DealDividends`
+  3. 查回 `eod_swap_position`，断言 `ΔSwapPositionValue + ΔRealizedPnl == 0`
+- 这是独立的工程任务，需要专门投入时间，不适合在排查任务里匆忙做
+

+# 互换收益结算审核后状态卡死、阻止收盘问题分析
+
+> 本文分析到期互换"收益结算（互换）审核通过后，交易状态不流转，导致收盘到期检查一直阻止"的问题。
+> 成文于 2026-07-01。
+
+---
+
+## 一、问题概述
+
+**复现场景**：一笔互换交易到期日（如 2026-06-29），用户在界面做"收益结算（互换）"并审核通过，但：
+- 交易状态没变成"已到期"或"已平仓"，仍是"确认成交"
+- 不管做多少次收益结算+审核，状态依旧不变
+- 收盘报错：`[检查当日到期交易]当日到期的场外交易未全部操作完成，请操作完成后再执行收盘操作:收益互换 GLMS-20260427-0001`
+
+---
+
+## 二、根因：审核路径 ApproveSwapTrade 漏了到期日判断
+
+### 代码对照（铁证）
+
+**免审核路径 `SwapIncome`（正确，基线就有）** — `SwapDealService.cs:1481-1485`：
+```csharp
+if (td.ExerciseDate <= unwindData.ValueDate)   // 判断到期
+{
+    td.Notional = 0;
+    td.StockEqvNotional = 0;
+    td.TradeStatus = "已到期";                  // ✅ 到期 → 已到期
+}
+```
+
+**审核路径 `ApproveSwapTrade`（漏了）** — `SwapDealService.cs:1525-1538`：
+```csharp
+if (swapEvent.unwindData.CloseMethod == (int)CloseMethodEnum.全部平仓)
+    td.TradeStatus = "已平仓";
+else
+{
+    td.TradeStatus = ConsTrade.确认成交;   // ❌ 到期互换落到这里！没有 ExerciseDate 判断
+    td.HasPartialUnWind = 1;
+}
+```
+
+`ApproveSwapTrade` **完全没有 `ExerciseDate` 到期判断**，而互换操作的 `CloseMethod` 又是默认值 0（`InitIncome` cs:216 从不设它）→ 0 ≠ 全部平仓(1) → 走 else → 状态退回"确认成交"。
+
+### 为什么互换必然走 else 分支
+
+- `CloseMethodEnum`：Unknown=0 / 全部平仓=1 / 部分平仓=2
+- 互换初始化 `InitIncome`（cs:216-292）**从不给 `unwindData.CloseMethod` 赋值** → 默认 0
+- 只有平仓路径（`InitUnwind`/`InitLongShortUnwind`）才设 `CloseMethod=全部平仓`
+- 0 ≠ 1 → 必走 else → 退回"确认成交"
+
+### 收盘检查为什么一直阻止
+
+`EodCheckMaturityTrade.cs:27-33`（到期检查）：
+```csharp
+var predicate = PredicateBuilder.Create<trade>(t =>
+    t.ExerciseDate >= startDate && t.ExerciseDate <= settleDate   // 今日到期
+    && t.TradeStatus == ConsTrade.确认成交                        // ★ 状态还是"确认成交"
+    && t.SettlementFlag != 1);
+```
+
+判断口径只看 `TradeStatus`。`TradeCompleteStatus = { 已到期, 已执行, 已平仓 }`（ConsTrade.cs:33）。审核后状态停在"确认成交"（不在完成列表里）→ 永远命中 → 永远阻止。
+
+---
+
+## 三、关于"提交数量但审核时数量0"
+
+用户还反馈"提交了数量但审核时候数量0"。经查：
+
+1. `InitIncome`（cs:216-292）**从没给 `unwindData.CloseQty` 赋值**（对比 `InitUnwind` cs:90 有赋值）→ `CloseQty` 默认 0
+2. `SaveSwapDeal`（cs:1597）的 `item.Quantity = unwindData.CloseQty` 被 `eventType == 平仓` 条件挡住 → 互换(3)不执行
+
+但这不是核心问题——**核心是状态没流转**。互换的 Quantity 语义与平仓不同（互换是收益结清，不是按数量平仓），数量为 0 可能是设计如此。状态卡死才是阻止收盘的直接原因。
+
+---
+
+## 四、引入时间（git blame）
+
+| 路径 | 提交 | 时间 | 说明 |
+|------|------|------|------|
+| `SwapIncome` 到期判断（正确）| `f9d8a256` | 2024-05-09 | 山证基线，一直有 |
+| `ApproveSwapTrade` 状态分支（漏判断）| `083848fb` | 2025-05-28 | 审核流程重构，漏同步 ExerciseDate 判断 |
+
+`083848fb`（2025-05-28）重构审核流程时把状态分支改成 `CloseMethod==全部平仓` 判断，但**忘了同步 `SwapIncome` 里的 `ExerciseDate` 到期判断**。
+
+---
+
+## 五、涉及文件
+
+| 文件:行号 | 问题 |
+|----------|------|
+| `SwapDealService.cs:1525-1538`（ApproveSwapTrade）| **漏 ExerciseDate 判断**，到期互换退回"确认成交" |
+| `SwapDealService.cs:1481-1485`（SwapIncome）| 正确对照（有到期判断）|
+| `SwapDealService.cs:216`（InitIncome）| 不设 CloseMethod → 默认 0，必然走 else |
+| `EodCheckMaturityTrade.cs:27-33` | 阻止收盘的检查（只认 TradeStatus）|
+| `ConsTrade.cs:33` | TradeCompleteStatus 定义（确认成交不在内）|
+
+---
+
+## 六、修复方向（最小改动）
+
+在 `ApproveSwapTrade`（cs:1534-1538）的 else 分支补到期判断，与 `SwapIncome` 对齐：
+
+```csharp
+else
+{
+    // 补：到期互换应设为"已到期"（与 SwapIncome cs:1481 对齐）
+    if (td.ExerciseDate <= swapEvent.unwindData.ValueDate)
+    {
+        td.Notional = 0;
+        td.StockEqvNotional = 0;
+        td.TradeStatus = "已到期";
+    }
+    else
+    {
+        td.TradeStatus = ConsTrade.确认成交;
+        td.HasPartialUnWind = 1;
+    }
+}
+```
+
+改后到期互换审核通过 → 状态正确变成"已到期" → 收盘检查通过。
+
+---
+
+## 七、团队决策问题
+
+1. **互换的 CloseMethod 是否应该设值**：当前 `InitIncome` 不设 CloseMethod（默认 0），是否应在互换初始化时根据是否全额结清设为"全部平仓"？这会影响 `ApproveSwapTrade` 走哪个分支。
+2. **互换 Quantity=0 是否符合预期**：`InitIncome` 不设 CloseQty，导致互换 flow_event 的 Quantity=0。需业务确认这是设计意图还是遗漏。
+3. **历史卡住的交易怎么处理**：GLMS-20260427-0001 等已卡住的交易，是否需要手动改 TradeStatus 为"已到期"才能继续收盘？

+# Seams 模式实践指南 — 遗留代码可测试化方法论
+
+## 背景
+
+本指南基于互换合约交易系统（OTC衍生品后台）的实际改造经验提炼。目标是在不改变生产行为的前提下，让 LLM 能够验证核心业务逻辑的正确性。
+
+## 核心模式：Protected Virtual Seams
+
+### 原理
+
+遗留代码的典型问题：业务逻辑与基础设施（数据库、缓存、外部服务）紧耦合。直接单元测试需要真实数据库，成本极高。
+
+**Seams 模式**的解法：
+1. 识别方法中的外部依赖点
+2. 提取 `protected virtual` 方法作为"接缝"
+3. 默认实现保持原有行为
+4. 测试时创建子类 override，注入内存数据
+
+```csharp
+// 生产代码：添加虚方法
+protected virtual trade FindTrade(int swapTradeId)
+    => DbContext.trade.Find(swapTradeId);
+
+// 测试代码：override 返回内存数据
+protected override trade FindTrade(int swapTradeId)
+    => _trades.TryGetValue(swapTradeId, out var t) ? t : null;
+```
+
+**关键原则：最小侵入**
+- 不改变方法签名
+- 不改变访问修饰符（除了 private → protected）
+- 不引入新接口或依赖注入框架
+- 默认实现完全等价于原有行为
+
+### 依赖类型与提取策略
+
+| 依赖类型 | 示例 | 提取策略 |
+|----------|------|---------|
+| DbContext 查询 | `DbContext.trade.Where(predicate)` | 提取为 `FindXxx()` 虚方法 |
+| DbContext 写入 | `DbContext.eod_swap_position.Add(entity)` | 提取为 `PersistXxx()` 虚方法 |
+| DbContext 事务 | `DbContext.Database.BeginTransaction()` | 提取为 `ExecuteInTransaction(Action)` |
+| DbContext 保存 | `DbContext.SaveChanges()` | 提取为 `SaveAllChanges()` |
+| new XxxService() | `new EodCurrencyRateService(UserInfo).GetRate()` | 提取为业务语义虚方法如 `GetCurrencyRate()` |
+| 静态方法 | `EodPriceQueryService.TryGetPrice()` | 提取为虚方法包装 |
+| DataCacheProvider | `DataCacheProvider.GetUnderlyingDataSource()` | 提取为 `GetUnderlyingData()` |
+| 基类非虚方法 | `base.InitInterestDate()` | 提取为 Wrapper 虚方法 |
+
+## 可测试子类模式
+
+### 构造函数注入
+
+```csharp
+public class TestableSwapEodPositionService : SwapEodPositionService
+{
+    private readonly Func<string, DateTime, decimal> _priceProvider;
+    private readonly Func<decimal> _currencyRateProvider;
+
+    public TestableSwapEodPositionService(
+        OptUserInfo optUser,
+        Func<string, DateTime, decimal> priceProvider = null,
+        Func<decimal> currencyRateProvider = null
+    ) : base(optUser)
+    {
+        _priceProvider = priceProvider ?? ((code, date) => 100m);
+        _currencyRateProvider = currencyRateProvider ?? (() => 1m);
+    }
+
+    protected override decimal GetUnderlyingPrice(string code, DateTime date)
+        => _priceProvider(code, date);
+}
+```
+
+### 输出捕获
+
+```csharp
+public List<eod_swap_position> CreatedEodPositions { get; } = new();
+
+protected override void PersistEodSwapPosition(eod_swap_position position)
+    => CreatedEodPositions.Add(position);
+```
+
+### 事务 No-op
+
+```csharp
+protected override void ExecuteInTransaction(Action action)
+    => action();  // 测试中跳过事务
+```
+
+### 委托参数过多时用自定义委托
+
+```csharp
+// Func 最多16个类型参数，超出时用 delegate
+public delegate bool InterestDateDelegate(
+    DateTime? preSettleDate, DateTime valueDate, trade td,
+    bool tdClose, bool calcLastNew,
+    out DateTime interestStart, out DateTime interestEnd);
+```
+
+## 测试体系设计
+
+### 三层测试
+
+| 层级 | 目的 | 特点 |
+|------|------|------|
+| 合成测试 | 验证业务逻辑正确性 | 程序化构造输入，断言输出字段 |
+| 黄金文件 | 回归保护 | JSON 存储 input/output，回放对比 |
+| 端到端测试 | 验证方法间协作 | 调用主入口方法，验证全流程 |
+
+### 合成测试模式
+
+```csharp
+[TestMethod]
+public void Scenario3_HasPrevEod_HasCloseEvent_ShouldUpdatePosition()
+{
+    // Arrange
+    var prevEod = CreateEodPosition(positionId: 1, qty: 1000, grossPrice: 1.0020m);
+    var service = CreateService();
+    var positions = new List<swap_position> { CreatePosition(id: 1, qty: 1000) };
+    var flowEvents = new List<swap_flow_event>
+    {
+        CreateCloseFlowEvent(positionId: 1, qty: 400, markClosePnl: 500m)
+    };
+
+    // Act
+    var result = service.ExecuteDealFloatPositions(
+        positions, new List<swap_position>(),
+        new List<eod_swap_position> { prevEod }, new List<eod_swap_position>(),
+        SettleDate, CreateTrade(), PreSettleDate, flowEvents);
+
+    // Assert
+    Assert.AreEqual(1, result.Count);
+    Assert.AreEqual(600, result[0].PosiQuantity, "1000-400=600");
+    Assert.AreEqual(400, result[0].TdCloseQty);
+}
+```
+
+### 黄金文件格式
+
+```json
+{
+  "Scenario": "有平仓事件→更新",
+  "ScenarioId": 3,
+  "TradeDate": "2025-04-24T00:00:00",
+  "Description": "...",
+  "SwapTradeId": 100,
+  "Positions": [...],
+  "PrevEodPositions": [...],
+  "FlowEvents": [...],
+  "ExpectedCreatedPositions": [...],
+  "ExpectError": false
+}
+```
+
+### 回放测试框架
+
+```csharp
+[TestMethod]
+public void ReplayAllGoldenFiles()
+{
+    var files = Directory.GetFiles(GoldenDir, "*.json");
+    foreach (var file in files)
+    {
+        var golden = Deserialize(file);
+        var service = CreateService(golden);
+        var result = Execute(service, golden);
+        AssertResults(result, golden.ExpectedCreatedPositions);
+    }
+}
+```
+
+## 渐进式改造节奏
+
+### 推荐：由内而外，逐层深入
+
+```
+Week 1: 子方法可测试化（ComposePage, DealFloatPositions, DealInterests）
+Week 2: 主入口方法可测试化（SwapPositionCompose 端到端）
+Week 3: 横向扩展到其他 Service（SwapDealService, SwapTradeService）
+```
+
+### 每个 Service 的改造步骤
+
+1. **分析**：列出方法清单，统计硬依赖密度（deps/100行），选择 ROI 最高的方法
+2. **提取**：添加 `#region 可测试化`，逐一提取虚方法
+3. **重构**：将硬依赖调用替换为虚方法调用
+4. **子类**：创建 TestableXxxService，override 虚方法
+5. **测试**：编写合成测试 → 黄金文件 → 回放测试
+6. **验证**：全量测试通过，无回归
+
+### 虚方法命名约定
+
+| 类型 | 命名 | 示例 |
+|------|------|------|
+| 查询 | `FindXxx` | `FindTrade`, `FindEodSwapPositions` |
+| 持久化 | `PersistXxx` | `PersistEodSwapPosition`, `PersistFlowEvent` |
+| 计算 | `CalcXxx` / `GetXxx` | `CalcBondPayment`, `GetCurrencyRate` |
+| 操作 | `ExecuteXxx` / `SaveXxx` | `ExecuteInTransaction`, `SaveAllChanges` |
+| 包装 | `XxxWrapper` | `InitInterestDateWrapper` |
+
+## 实际成果
+
+### SwapEodPositionService（Day 5a-5d）
+
+| 指标 | 数值 |
+|------|------|
+| 虚方法数 | 29 |
+| 重构方法数 | 7 |
+| 合成测试 | 24 |
+| 黄金文件 | 18 |
+| 端到端测试 | 6 |
+| 总测试数 | 65（56 passed + 9 skipped recording） |
+
+### SwapDealService（Day 6a）
+
+| 指标 | 数值 |
+|------|------|
+| 虚方法数 | 2 |
+| 合成测试 | 6 |
+| 总测试数 | 71（62 passed + 9 skipped） |
+
+## 经验教训
+
+1. **先识别路径再提取**：DealFloatPositions 有 3 条路径、DealInterests 有 5 条路径，理解路由逻辑后才知道哪些虚方法可以复用
+2. **黄金文件需要 rebuild 才生效**：JSON 资源文件通过 csproj 的 CopyToOutputDirectory 复制，修改后需要 rebuild
+3. **枚举值别靠记忆**：平仓=2、互换=3、自动互换=4 — 写黄金文件时查枚举定义
+4. **Func 参数上限**：C# Func 最多 16 个类型参数，超出用自定义 delegate
+5. **swap_position.SwapIntervalList 是只读**：从 InterestSwapInterval JSON 反序列化，不能直接赋值
+6. **匹配键是 id 不是 PositionId**：DealFloatPositions 用 `posi.id` 匹配 eodPosition 和 flowEvent

+# 互换部分平仓后：利息端/预付金"平仓盈亏默认值"偏大问题分析
+
+> 本文分析收益互换"昨天收益结算（互换）→ 收盘 → 今天平仓"场景下，**预付金平仓盈亏和利息端平仓盈亏的默认值计算偏大**的问题：根因、涉及的文件、如何确认、修复方案与自测方法。
+> 成文于 2026-07-01。
+
+---
+
+## 一、问题概述
+
+**复现场景**：
+1. 第一天：对互换交易做**收益结算（互换）** → 收盘
+2. 第二天：再次进入**平仓**页
+
+**现象**：平仓页的"预付金平仓盈亏"和"利息端平仓盈亏"**默认值偏大**——包含了之前已经通过互换/收益结算平掉的那部分利息，没有扣除。
+
+**用户怀疑**："这部分是不是没有减去之前已经平掉的部分？"——**怀疑成立**，下文逐层证明。
+
+---
+
+## 二、数据流：这两个默认值从哪来
+
+### 关键结论：默认值是后端算的，前端只展示
+
+前端 `unwindSwapTrade.js` **不计算**这两个默认值，只是把后端返回的 `InterestClosePnL` 原样填到输入框：
+
+| 界面字段 | 绑定字段 | 数据来源 |
+|---------|---------|---------|
+| 预付金平仓盈亏 | `marginList[].InterestClosePnL` | 后端接口返回 |
+| 利息端平仓盈亏 | `interestList[].InterestClosePnL` | 后端接口返回 |
+| 浮动端平仓盈亏 | `floatPosition.FloatPnlSum`（前端现算）| 前端 `calcFloatClosePnl` |
+
+前端调接口（`unwindSwapTrade.js:264-265`）：
+```js
+{ valueDate, unwindDate, tradeId, closePercent, eventType: 2 }
+```
+
+### 后端接口链路
+
+```
+POST /swaptrade2/GetUnwindInterestList  (SwapTrade2Controller.cs:287)
+  └─ SwapDealService.GetUnwindInterests        (SwapDealService.cs:302)
+       ├─ 取 closeList = 当天已完成的平仓/互换事件  (cs:336)

+            │         ↑ 这里全量重算利息，不扣历史已平部分
+            └─ 同日去重：closeList 扣减            (cs:418-446)  ← 只扣当天，跨天漏
+```
+

+
+## 三、根因：互换结清后 eod 的 InterestProfitSum（待实现）没扣减已实现部分
+
+> ✅ 6-29 收盘后用交易 1889（GLMS-20260616-0004）三天对比实测坐实。用户的判断"从开头算了"正确。
+
+### 3.1 实测坐实（6-29 收盘后，6-29/6-30/7-1 三天对比）
+
+利息腿 PositionId=34695（标的期初全价），29号收益结算(互换) + 29号收盘后：
+
+```
+日期         平仓默认值    eod待实现(IPS)   eod已实现(RI)   说明
+6-29(互换前)  0.0003      77.26(6-28eod)   0.00           当天看=0，正确
+6-30         83.6986     77.26(6-29eod)   77.26          偏大！
+7-1          90.1370     77.26(6-29eod)   77.26          更偏大！
+```
+
+**核心铁证**：6-29 收盘后，`InterestProfitSum`（待实现）= **77.26**，`RealizedInterest`（已实现）= **77.26**。**两个相等——互换已经把全部利息实现了（77.26），但"待实现"没归零**，还是 77.26。
+
+所以后续平仓默认值 = 待实现(77.26) + 每日增量(6.44/天)。6-30 = 77.26+6.44=83.70，7-1 = 77.26+12.88=90.14。**偏大的量正是那个本该归零却没归零的 77.26**。
+
+### 3.2 根因机制：eod 扣减公式对"互换"场景失效
+
+`SwapEodPositionService.cs:829`（收盘更新待实现利息）：
+```csharp
+InterestIncomeSum = pre.InterestIncomeSum + TdInterestIncome - TdCloseInterest;
+//                  = 77.26(6-28)      + 77.26(当日新计)  - 77.26(当日互换实现)
+//                  = 77.26  ← 抵消了，没扣减！
+```
+
+**为什么抵消**：互换操作当日会重新计息（`TdInterestIncome` = 77.26，相当于把到期前的利息算了一遍），同时互换实现（`TdCloseInterest` = 77.26）。两个相等，相减为 0，所以 `InterestIncomeSum` 维持在 77.26 不变。
+
+**正常平仓不会这样**：平仓时 `TdInterestIncome` 是"昨日到今日的增量"（小），`TdCloseInterest` 是"平仓实现的全部"（大），两者不等 → 能扣减。但互换（收益结算）的计息逻辑把全程利息都算了一遍（`TdInterestIncome ≈ TdCloseInterest`），导致扣减失效。
+
+### 3.3 CalcDailySimpleInterest 读这个"没扣减的待实现"作为起点
+
+`SwapDealService.cs:771`（CalcDailySimpleInterest）：
+```csharp
+decimal interestProfitSum = preEodPosition.InterestProfitSum;  // :774 读 77.26（本该归零）
+decimal interest = interestProfitSum * closePercent;           // :776 起点 = 77.26
+for (int i = 0; i <= calcDays; i++)                            // :784 补算昨日之后增量
+{
+    if (accrueDate > preEodPosition.ValueDate)                 // :789
+        interest += interest1;                                  // :823 每天+6.44
+}
+// 结果：6-30 = 77.26 + 6.44 = 83.70（偏大，含已实现的77.26）
+```
+
+`GetInterests` 的同日去重（cs:435-443）只覆盖"当天"的已完成事件，29号互换 EventDate=6-29 ≠ 平仓日 6-30 → **跨天去重不生效**。
+
+### 3.4 根因总结
+
+```
+互换结清后正确的状态应该是：InterestProfitSum(待实现) = 0（全部已实现）
+但实际：InterestProfitSum = 77.26（= RealizedInterest，没归零）
+         ↓ 原因
+eod 公式 cs:829：IPS = pre.IPS + TdInterestIncome - TdCloseInterest
+                   互换时 TdInterestIncome ≈ TdCloseInterest → 抵消 → IPS 不变
+         ↓ 后果
+后续平仓默认值 = IPS(77.26，本该0) + 增量 → 偏大 77.26
+```

+| 后端·eod扣减待实现 | `SwapEodPositionService.cs:829` | InterestIncomeSum 扣 TdCloseInterest（**有扣减**）|
+| 前端·展示（非源）| `unwindSwapTrade.js:262-275` | 仅展示后端值 |
+
+> **前端不是 bug 源**：前端只把后端 `InterestClosePnL` 填进输入框，无额外计算。
+
+---
+
+## 五、引入时间（git blame）
+
+| 代码点 | 提交 | 时间 | 说明 |
+|--------|------|------|------|
+| `interestProfitSum = preEodPosition.InterestProfitSum`（cs:774）| `f9d8a256` | 2024-05-09 | 山证基线 |
+| `interest = interestProfitSum * closePercent`（cs:776）| `6708878d` | 2026-04-13 hjhan | 改起点为×closePercent |
+| 同日去重（cs:435-443）| `535497c68` | 2026-06-04 吴方海 | 加同日去重补救，仅覆盖当天 |
+| eod 扣减 TdCloseInterest（cs:829）| 基线 | 2024-05 | eod 层有扣减已实现 |
+
+**结论**：利息计算链路是基线设计，经历过多次局部修补（`6708878d` 改起点、`535497c68` 加同日去重）。**具体哪个改动引入了用户反馈的偏差，需用干净样本定位**。
+
+---
+
+## 六、如何确认 bug（已坐实）
+
+### 6.1 实测坐实（交易 1889，6-29 收盘后三天对比，Step0d）
+
+用真实的 `GetUnwindInterests` 分别测 6-29/6-30/7-1 三天，结果（PositionId=34695 标的期初全价）：
+
+```
+日期         平仓默认值    eod待实现(IPS)   eod已实现(RI)   说明
+6-29(互换前)  0.0003      77.26(6-28eod)   0.00           当天看=0，正确
+6-30         83.6986     77.26(6-29eod)   77.26          偏大！含已实现的77.26
+7-1          90.1370     77.26(6-29eod)   77.26          更偏大！
+```
+
+**核心铁证**：6-29 收盘后 `InterestProfitSum`（待实现）= 77.26 = `RealizedInterest`（已实现）= 77.26。互换已全部实现，但待实现没归零 → 后续默认值 = 77.26(本该0) + 增量 → 偏大。
+
+### 6.2 录制测试
+
+`SwapPartialUnwindInterestDefaultTest.Step0d_DiagnoseTrade1889_FullTimeline`：
+- 展示 swap_event 全历史（甄别回退）
+- 展示 eod 按日序列（InterestProfitSum/RealizedInterest 演变）
+- 调用真实 `GetUnwindInterests` 拿默认值
+- 对比"默认值 vs eod待实现"判定是否重复计入
+
+---
+
+## 七、修复方案
+
+> 根因已精确定位：互换结清后 `InterestProfitSum` 没归零（= RealizedInterest），导致后续平仓默认值偏大。
+
+### 方案 A（推荐·最小改动）：平仓默认值起点扣除 RealizedInterest
+
+`CalcDailySimpleInterest`（cs:774/776）读 `InterestProfitSum` 作为起点。既然 `InterestProfitSum` 没扣已实现，就在这里扣：
+
+```csharp
+// SwapDealService.cs:774-776  改前
+decimal interestProfitSum = preEodPosition.InterestProfitSum;
+var TdInterestPrincipal = preEodPosition.TdInterestPrincipal;
+decimal interest = interestProfitSum * closePercent;
+
+// 改后：扣除已通过互换/平仓实现的部分
+decimal interestProfitSum = preEodPosition.InterestProfitSum - preEodPosition.RealizedInterest;
+var TdInterestPrincipal = preEodPosition.TdInterestPrincipal;
+decimal interest = interestProfitSum * closePercent;
+```
+
+**原理**：`InterestProfitSum`（待实现累计）- `RealizedInterest`（已实现累计）= **真正未实现的利息**。互换结清后 IPS=77.26、RI=77.26，相减=0，起点正确归零。后续只加增量。
+
+**验证**（用 1889 数据）：
+- 6-30 默认值 = (77.26 - 77.26) + 6.44(一天增量) = **6.44** ✅（而非偏大的 83.70）
+- 7-1 默认值 = (77.26 - 77.26) + 12.88 = **12.88** ✅
+
+**优点**：改动 1 行，利用现有字段，覆盖单利路径。
+**风险**：需确认所有场景下 `RealizedInterest` 都正确累加了已实现利息。对复利路径（`CalcDailyCompoundInterest` cs:705）需同步检查。
+
+### 方案 B（治本）：修正 eod 扣减公式，让互换结清后 InterestProfitSum 正确归零
+
+根因在 `SwapEodPositionService.cs:829`——互换时 `TdInterestIncome ≈ TdCloseInterest` 导致扣减抵消。需在互换（EventType=互换/自动互换）的收盘路径里特殊处理：
+
+```csharp
+// SwapEodPositionService.cs:829 附近
+// 互换结清时，待实现利息应直接归零（已全部实现），不能靠 TdInterestIncome - TdCloseInterest 抵消
+if (isSwap && closePercent == 1)   // 全量互换结清
+{
+    newEodPayPosition.InterestIncomeSum = 0;  // 待实现归零
+}
+else
+{
+    newEodPayPosition.InterestIncomeSum = eodPayPosition.InterestIncomeSum
+                                        + newEodPayPosition.TdInterestIncome
+                                        - newEodPayPosition.TdCloseInterest;
+}
+```
+
+**优点**：从源头修正，所有读 `InterestProfitSum` 的地方都受益。
+**缺点**：改动 eod 核心逻辑，风险较大，需全面回归。
+
+### 方案 C（补充）：closeList 扩展到历史
+
+`GetUnwindInterests` 的 closeList（cs:336）只查当天，跨天互换事件漏掉。可扩展到历史：
+```csharp
+// cs:336 改 UnwindDate == unwindDate 为 UnwindDate <= unwindDate
+```
+但 cs:435 的 `!calcLast` 限制仍会导致算尾配置下不扣。作为方案 A/B 的补充。
+
+### 方案对比
+
+| 方案 | 改动量 | 治本程度 | 风险 |
+|------|--------|---------|------|
+| A（扣 RealizedInterest）| 极小(1行) | 修默认值 | 低，需验证字段口径 |
+| B（eod 公式归零）| 中 | 修源头 | 较高，改 eod 核心 |
+| C（closeList 扩历史）| 小 | 修去重 | 中，算尾仍漏 |
+
+**建议**：优先方案 A 止血（最小改动，直接验证），方案 B 作为后续治本。
+
+---
+
+## 八、录制 golden source
+
+### 已坐实（Step0d，交易 1889，6-29 收盘后三天对比）
+
+`Step0d_DiagnoseTrade1889_FullTimeline` 已调用真实服务坐实 bug：
+- 6-29 收盘后 InterestProfitSum(待实现)=77.26 = RealizedInterest(已实现)=77.26，**没归零**
+- 6-30 默认值 83.70 = 77.26(本该归零的待实现) + 6.44(一天增量) → 偏大 77.26
+- 7-1 默认值 90.14 = 77.26 + 12.88(两天增量) → 偏大 77.26
+
+### 录制 golden JSON
+
+当前 Step0d 是诊断输出（Console），尚未序列化 golden 文件。建议后续：
+1. 把 1889 的快照（swap_event + eod + 默认值结果）序列化为 `SwapPartialUnwindInterest/partial_unwind_trade_1889.json`
+2. 红灯断言：`Assert(默认值 > eod待实现 × 合理倍数)`，修复后反转
+
+### 注意：1889 有大量回退
+
+1889 有 52 条 swap_event（48 条 Invalid=True 的回退历史），测试环境反复回退复用。录制 golden 时需注意甄别有效事件（Invalid=False）。Step0d 已处理：只展示 Invalid=False 的 4 条有效事件。
+
+### 与前两个 golden 的关系
+
+三份 golden 构成"互换损益计算"回归基线：
+- `SwapDividend/`（分红重复计算）✅
+- `SwapReEodDeleteCash/`（重收盘误删资金）✅
+- `SwapPartialUnwindInterest/`（本次）⏳ Step0d 已坐实，golden 待序列化
+
+---
+
+## 九、团队决策问题
+
+1. **业务口径确认**：部分平仓/互换后再次平仓，利息端盈亏默认值应该是"剩余持仓的应计利息（扣已实现）"？当前行为是"从头算（含已实现）"，业务上预期哪个？
+2. **方案选择**：方案 A（closeList 扩历史，推荐）/ 方案 B（扣 RealizedInterest）？
+3. **回退复用的影响**：1889 被反复回退，eod 只到 6-22（29号收盘数据疑似被回退清掉）。需确认：回退是否应该清理 eod？还是回退后 eod 应保留？
+4. **是否补单测**：建议把 Step0d 的坐实逻辑固化为 golden + 红灯断言，防止复发。

+# 互换重收盘误删"手动互换"资金记录：问题分析与修复方案
+
+> 本文分析互换交易"重新收盘/重算 EOD"后，**用户手动互换产生的资金记录被错误删除**的问题：根因、引入时间、三种修复方案与自测方法。
+> 成文于 2026-07-01，排查范围覆盖 `5f97909f`（2026-04-29）至当前 HEAD。
+
+---
+
+## 一、问题概述
+
+互换交易每次"重新收盘"（EOD 重算）时，会先清理旧数据再重算。当前实现会把**用户手动互换**产生的资金记录（`ClientCashInCashOut` 表中 `Action=系统操作-互换` 的记录）**一并删除**，导致历史资金流水丢失。
+
+**复现条件**：一笔互换交易，用户已手动做过互换（EventType=3，生成 `Action=系统操作-互换` 资金记录），随后对该交易日重新收盘 → 该手动互换资金记录消失。
+
+---
+
+## 二、先澄清概念：哪些表是什么
+
+| 表名 | 实体类 | 用途 | 与本问题关系 |
+|------|--------|------|-------------|
+| `ClientCashInCashOut` | `ClientCashInCashOut.cs:232` | **资金记录/出入金流水**（金额、方向、银行账户）| ⚠️ **被误删的就是这张表** |
+| `swap_event` | `SwapEvent.cs` | 互换事件主记录（含 `ClientCashId` 外键）| 删除时按 EventType 过滤，安全 |
+| `swap_flow_event` | `SwapFlowEvent.cs:14` | 开平仓事件明细（盈亏/计息），通过 `ClientCashId` 关联资金记录 | EOD 清理时按 EventType 过滤，**未误删** |
+| ~~swap_capital_flow / swap_fund_flow~~ | 不存在 | —— | 代码库中无此表 |
+
+**关键**：`swap_flow_event` 不是"资金记录"，它和 `ClientCashInCashOut` 通过 `ClientCashId` 字段 1:1 关联。本问题中 `swap_flow_event` 没被误删，被误删的是 `ClientCashInCashOut`。
+
+---
+
+## 三、根因：删除逻辑按 Action 字符串过滤，无法区分手动/自动
+
+### 问题代码位置
+
+`YLErpDAL/Modules/SwapModule/SwapTradeBaseService.cs` 的 `ClearSwapPositions` 方法，**第 398–409 行**：
+
+```csharp
+// SwapTradeBaseService.cs:398-409（bug 所在）
+var swapTradeIds = swapEvents.Select(s => s.SwapTradeId).Distinct().ToList();
+var actions = new List<string>() { ClientCashInCashOut.系统操作_预付金返息, ClientCashInCashOut.系统操作_互换 };
+var premiumCashRecords = DbContext.ClientCashInCashOut
+    .Where(x => swapTradeIds.Contains(x.TradeId ?? 0)
+             && x.HappenDate >= valueDate
+             && actions.Contains(x.Action))
+    .ToList();
+if (premiumCashRecords.Any())
+{
+    DbContext.ClientCashInCashOut.RemoveRange(premiumCashRecords);
+}
+```
+
+### 为什么会误删
+
+`系统操作_互换` 这个 Action 字符串**手动互换和自动互换共用**，而 `ClientCashInCashOut` 表**没有任何字段区分手动 vs 自动来源**：
+
+| 来源 | 写入位置 | Action 值 |
+|------|---------|----------|
+| 手动互换 `SwapIncome` | `SwapDealService.cs:1471` | `系统操作-互换` |
+| 手动互换 `ApproveSwapTrade`（审批通过）| `SwapDealService.cs:1519` | `系统操作-互换` |
+| 自动互换（利息腿）| `SwapEodPositionService.cs:516` | `系统操作-互换` |
+| 自动互换（分红）| `SwapEodPositionService.cs:531` | `系统操作-互换` |
+
+`AddClientCashInCashOut`（`SwapTradeBaseService.cs:285-318`）生成资金记录时**不设任何来源标记**。所以按 `TradeId + HappenDate>=valueDate + Action` 删除，无法过滤掉手动互换的记录。
+
+> 注：第 391–396 行按 `swap_event.ClientCashId` 精准删除是**安全**的（只删自动互换 event 自己链接的那条）。**第 398–409 行的"按 Action 兜底模糊删除"才是误删元凶。**
+
+---
+
+## 四、引入时间线：是"修每次收盘多出一条"修出来的新 bug
+
+本 bug 是修复"重复收盘导致互换收入重复计入"时，删除范围逐步扩大，最终修过头引入的。三次提交演进：
+
+| 时间 | 提交 | 作者 | 改动 | 性质 |
+|------|------|------|------|------|
+| **2026-04-29** | `5f97909f` | hjhan | `fix(swap): 修复重复收盘导致互换收入(含预付金利息)重复计入的问题`——在删 `swap_event` 前按 `swap_event.ClientCashId` 精准删除关联资金记录 | ✅ **正确** |
+| **2026-05-11** | `ebe711d3` | 吴方海 | `#EQD-5850 预付金返息的发生时间有问题`——自动互换把预付金返息单独拆条记录，并在删除时**新增按 `TradeId + 日期 + Action=预付金返息` 批删** | ⚠️ 首次把删除从"按主键ID"放宽到"按Action字符串" |
+| **2026-05-14** | `44e89726` | 吴方海 | `收盘自动互换，需要将当前计息基数给回到持仓名义本金或固定值`——**把 `系统操作_互换` 加进删除 Action 列表** | ❌ **误删手动互换的直接引入点** |
+
+`44e89726` 的 diff（实测验证）只改一行：
+
+```diff
+-                                 && x.Action == ClientCashInCashOut.系统操作_预付金返息)
++                    var actions = new List<string>() { ClientCashInCashOut.系统操作_预付金返息, ClientCashInCashOut.系统操作_互换 };
++                                 && actions.Contains(x.Action))
+```
+
+加进去的理由是"自动互换的互换主金额也要清掉重算"，但没意识到 `系统操作_互换` 跟手动互换共用。
+
+---
+
+## 五、约束分析：为什么不能简单回退到 `5f97909f`
+
+`5f97909f` 的精准删除（按 `swap_event.ClientCashId`）在**当时**是对的，但现在的自动互换逻辑已演进——**一次自动互换会生成多条资金记录**：
+
+`SaveAutoSwapDeal`（`SwapEodPositionService.cs:506`）按条件最多生成 3 条 `ClientCashInCashOut`：
+- `:516` 利息腿 `系统操作_互换`（`SwapCloseAmount != 0` 时）
+- `:522` 预付金 `系统操作_预付金返息`（`SwapMarginRebatePnl != 0` 时）
+- `:531` 分红 `系统操作_互换`（`SwapDividendPnl != 0` 时）
+
+但 `swap_event.ClientCashId`（`:535`）**只指向最后一条非 0 的 id**，前面的被覆盖。所以单纯按 `ClientCashId` 删，会**漏删**自动互换的前几条资金记录 → 复发"每次收盘多出一条"老 bug（`5f97909f` 当时修的那个）。
+
+> 手动互换也有同样结构：`SwapIncome:1471` 生成主金额（id 存进 event），`:1474` 预付金返息的 id 被丢弃。手动互换若被精准删除只删主金额那条，预付金返息会成"孤儿"残留——但手动互换**本就不该被重收盘删除**，所以这反而是"正确残留"。
+
+---
+
+## 六、修复方案（三选一，供团队决策）
+
+### 方案 A（推荐，最小改动 + 治本）：按 swap_event 链 + EventType 区分
+
+**思路**：删除自动互换资金记录时，**只删与自动互换 swap_event 关联的记录**，不碰手动互换的 swap_event（EventType=3/互换）。
+
+删除条件从"按 Action 字符串"改为"按 `swap_event.ClientCashId` 集合"，并扩展 `swap_event` 与资金记录的关联（让被覆盖的前几条也能被找到）：
+
+```csharp
+// 修复后（SwapTradeBaseService.cs:398-409 替换）
+// 注意：本方法入参 eventTypes 调用方只传了 {自动互换}（SwapEodPositionService.cs:92），
+// 所以 swapEvents 只含自动互换事件，手动互换事件不在内 —— 这就是安全的关键。
+var swapEventIds = swapEvents.Select(s => s.id).ToList();
+if (swapEventIds.Any())
+{
+    // 已有：按 swap_event.ClientCashId 精准删除主金额那条（保留第391-396行不变）
+
+    // 新增：按 swap_flow_event.ClientCashId 反查自动互换生成的全部资金记录
+    // 自动互换的每条 swap_flow_event 都带 ClientCashId（指向其资金记录）
+    var autoCashIds = DbContext.swap_flow_event
+        .Where(x => swapEventIds.Contains(x.EventId ?? 0) && x.ClientCashId > 0)
+        .Select(x => x.ClientCashId.Value)
+        .Distinct()
+        .ToList();
+    // 合并 swap_event.ClientCashId（主金额）
+    var eventCashIds = swapEvents.Where(s => s.ClientCashId > 0).Select(s => s.ClientCashId.Value);
+    autoCashIds = autoCashIds.Union(eventCashIds).ToList();
+
+    if (autoCashIds.Any())
+    {
+        var autoCashRecords = DbContext.ClientCashInCashOut
+            .Where(x => autoCashIds.Contains(x.id))
+            .ToList();
+        DbContext.ClientCashInCashOut.RemoveRange(autoCashRecords);
+    }
+}
+// ❌ 删除原来的"按 Action 字符串模糊删除"整段（第398-409行）
+```
+
+**⚠️ 关键前提缺陷（已确认）**：当前 `SaveAutoSwapDeal:538-542` 生成 flow_event 时**只设了 `EventId`，没有给 `ClientCashId` 赋值**：
+
+```csharp
+// SwapEodPositionService.cs:538-542（现状，缺 ClientCashId 赋值）
+flowEvents.ForEach(x =>
+{
+    x.EventId = swapEvent.id;
+    DbContext.swap_flow_event.Add(x);
+});
+```
+
+对比平仓路径 `ComposePage:685-686` 是有赋值的（`x.ClientCashId = clientCashId`）。所以**方案 A 必须同时补这个赋值**才能落地，否则反查 `swap_flow_event.ClientCashId` 会漏（复发"每次收盘多出一条"老 bug）。这是方案 A 的硬性前置改动，见第七节"改动 2"。
+
+**优点**：
+- 删除范围严格限定在自动互换事件链内，手动互换零误伤。
+- 不新增字段，不改数据库结构。
+- 语义清晰：删哪个 event，就删它关联的资金记录。
+
+**风险**：
+- 依赖 `swap_flow_event.ClientCashId` 的赋值完整性——当前自动互换分支未设，需补（改动 2）。
+- **资金记录与 flow_event 不是 1:1**（已确认）：
+  - `:420` 普通自动互换：生成 2 条资金记录（利息汇总 `:516` + 预付金汇总 `:522`），flow_event 是利息明细腿（多条）。
+  - `:498` 分红型自动互换：生成 1 条资金记录（分红汇总 `:531`），flow_event 是分红明细腿（多条）。
+  - 所以一条资金记录会被多条 flow_event 引用——改动 2 给 flow_event 设 ClientCashId 时，让同一笔互换的所有明细腿都指向该次生成的资金记录 id（利息腿指向 `:516` 的 id，预付金腿指向 `:522` 的 id）。删除时 `Distinct()` 去重即可。
+- 由于 `clientCashId` 变量在 `SaveAutoSwapDeal:516/522/531` 被多次覆盖，最终 `swap_event.ClientCashId`（`:535`）只存最后一条。**改动 2 必须在每次 `AddClientCashInCashOut` 后立即把 id 赋给对应的 flow_event 组**，不能依赖最后的 `clientCashId` 值。需配套单测兜底（见第八节）。
+
+---
+
+### 方案 B（保守）：保留 Action 过滤 + 加来源标记字段
+
+**思路**：给 `ClientCashInCashOut` 加一个来源字段区分手动/自动，删除时排除手动。
+
+```csharp
+// 1. 数据库迁移：ClientCashInCashOut 加列
+ALTER TABLE ClientCashInCashOut ADD COLUMN Source VARCHAR(20) DEFAULT '手动';
+
+// 2. AddClientCashInCashOut 增加来源参数（SwapTradeBaseService.cs:285）
+public int AddClientCashInCashOut(OtcTradeBase td, double amount, string action, DateTime valueDate, string source = "手动")
+{
+    ...
+    ee.Source = source;  // 新增
+    ...
+}
+
+// 3. 自动互换调用处传 source="自动"（SwapEodPositionService.cs:516/522/531）
+
+// 4. 删除过滤加排除条件（SwapTradeBaseService.cs:401-404）
+.Where(x => swapTradeIds.Contains(x.TradeId ?? 0)
+         && x.HappenDate >= valueDate
+         && actions.Contains(x.Action)
+         && x.Source == "自动")  // 新增：只删自动生成的
+```
+
+**优点**：删除逻辑最直白，改一处过滤条件即可。
+
+**缺点**：
+- 需要数据库迁移（生产加列），风险高。
+- 历史数据 `Source` 为默认值"手动"，但历史自动互换记录也是 NULL/默认 → 需数据回填脚本，否则老 bug 数据残留。
+- `Source` 字段语义需长期维护。
+
+---
+
+### 方案 C（最长远，工程量大）：用 swap_event 作为唯一删除入口
+
+**思路**：所有资金记录都必须挂到某个 `swap_event` 上（通过 `swap_flow_event.ClientCashId` 或新增 `ClientCashInCashOut.SwapEventId`），删除时一律按 event 链，彻底废弃按 Action 字符串删除。
+
+**优点**：语义最清晰，根除"按 Action 字符串删除"这类隐患。
+
+**缺点**：改动面大，需梳理所有生成资金记录的路径，确保都有 event 挂载。适合作为长期重构目标，不适合当下快速止血。
+
+---
+
+### 方案对比
+
+| 维度 | 方案A（推荐）| 方案B | 方案C |

+
+## 七、具体小修复代码（方案 A）
+
+### 改动 1：`SwapTradeBaseService.cs:398-409` 替换删除逻辑
+
+```csharp
+// ❌ 删除原第398-409行（按 Action 字符串模糊删除）
+// ✅ 替换为：按自动互换 swap_event 链精准删除
+
+// 自动互换一次可能生成多条资金记录（利息腿/预付金/分红），
+// 但 swap_event.ClientCashId 只指向最后一条。通过 swap_flow_event.ClientCashId
+// 反查自动互换事件关联的全部资金记录，避免误伤手动互换（EventType=3）。
+var autoFlowCashIds = DbContext.swap_flow_event
+    .Where(x => eventIds.Contains(x.EventId ?? 0) && x.ClientCashId > 0)
+    .Select(x => x.ClientCashId.Value)
+    .Distinct()
+    .ToList();
+var autoEventCashIds = swapEvents.Where(s => s.ClientCashId > 0).Select(s => s.ClientCashId.Value).ToList();
+autoFlowCashIds.AddRange(autoEventCashIds);
+autoFlowCashIds = autoFlowCashIds.Distinct().ToList();
+
+if (autoFlowCashIds.Any())
+{
+    var autoCashRecords = DbContext.ClientCashInCashOut
+        .Where(x => autoFlowCashIds.Contains(x.id))
+        .ToList();
+    DbContext.ClientCashInCashOut.RemoveRange(autoCashRecords);
+}
+```
+
+> 说明：`eventIds` 已在第 377 行算好（`swapEvents.Select(s => s.id)`）。本方法入参 `eventTypes` 在重收盘入口（`SwapEodPositionService.cs:92`）只传 `{自动互换}`，所以 `swapEvents` 只含自动互换事件，手动互换事件天然不在删除范围内 —— 这是安全的根本保证。
+
+### 改动 2（前提）：补全 `swap_flow_event.ClientCashId` 赋值
+
+自动互换 `SaveAutoSwapDeal`（`SwapEodPositionService.cs:506`）当前生成 flow_event 时只设了 `EventId`，没设 `ClientCashId`（`:538-542`、`:549-553`）。需补上，让方案 A 反查能找到全部资金记录。
+
+由于资金记录是"汇总"的（利息汇总/预付金汇总/分红汇总各 1 条），而 flow_event 是"明细腿"（多条），赋值规则是：**同一笔互换的明细腿都指向该次生成的资金记录 id**。需要在 `SaveAutoSwapDeal` 内用独立变量保存每条资金记录 id（不能依赖被覆盖的 `clientCashId`）：
+
+```csharp
+// SwapEodPositionService.cs:512-532 改造（用独立变量分别记录每个资金记录 id）
+int interestCashId = 0;   // 利息腿资金记录 id
+int premiumCashId = 0;    // 预付金腿资金记录 id
+int dividendCashId = 0;   // 分红资金记录 id
+
+if (unwindData.SwapCloseAmount != 0)
+{
+    interestCashId = AddClientCashInCashOut(td, Convert.ToDouble(-unwindData.SwapCloseAmount), ClientCashInCashOut.系统操作_互换, cashHappenDate);
+}
+if (unwindData.SwapMarginRebatePnl != 0)
+{
+    premiumCashId = AddClientCashInCashOut(td, Convert.ToDouble(-unwindData.SwapMarginRebatePnl), ClientCashInCashOut.系统操作_预付金返息, unwindData.ValueDate);
+}
+unwindData.SwapCloseAmount = unwindData.SwapRealizedPnL;
+if (unwindData.SwapDividendPnl != 0)
+{
+    var dividendPayDate = (dividendEvents != null && dividendEvents.Count > 0)
+        ? dividendEvents.First().PayDate.Value : unwindData.ValueDate;
+    dividendCashId = AddClientCashInCashOut(td, Convert.ToDouble(-unwindData.SwapDividendPnl), ClientCashInCashOut.系统操作_互换, dividendPayDate);
+}
+
+// 保留 clientCashId 给 swap_event（取最后一条非0，与原行为一致）
+int clientCashId = dividendCashId != 0 ? dividendCashId : (premiumCashId != 0 ? premiumCashId : interestCashId);
+```
+
+然后在 flow_event 赋值处按腿类型设 `ClientCashId`：
+
+```csharp
+// SwapEodPositionService.cs:536-555（flowEvents 是利息明细腿，指向利息资金记录）
+if (flowEvents != null)
+{
+    flowEvents.ForEach(x =>
+    {
+        x.EventId = swapEvent.id;
+        x.ClientCashId = interestCashId;  // 补：利息明细腿指向利息汇总资金记录
+        DbContext.swap_flow_event.Add(x);
+    });
+    UpdateInitalPostion(flowEvents, td.id);
+}
+// dividendEvents 是分红明细腿，指向分红资金记录
+if (dividendEvents != null)
+{
+    dividendEvents.ForEach(x =>
+    {
+        x.EventId = swapEvent.id;
+        x.ClientCashId = dividendCashId;  // 补：分红明细腿指向分红资金记录
+        DbContext.swap_flow_event.Add(x);
+    });
+    UpdateInitalPostion(dividendEvents, td.id);
+}
+```
+
+> ⚠️ 预付金资金记录 `premiumCashId` 没有对应的 flow_event 可挂载（预付金是单独汇总的，无明细腿）。它只能靠 `swap_event.ClientCashId`（当它是最后一条时）或方案 A 删除逻辑里单独处理。**实施时需验证：当只有预付金非0时，`swap_event.ClientCashId` 是否指向预付金那条**（按上面 `clientCashId` 三元表达式，`premiumCashId != 0` 时会取它，✓ 覆盖）。
+
+---
+
+## 八、如何自测
+
+### 自测 1：SQL 验证（最快，纯查询）
+
+找一笔**当天有手动互换操作**的互换交易，重收盘前后对比资金记录：
+
+```sql
+-- 步骤1：盘前记录手动互换资金记录的 id 快照
+SELECT id, TradeId, HappenDate, Action, Money, State, OptName, OptTime
+FROM ClientCashInCashOut
+WHERE TradeId = <手动互换过的交易ID>
+  AND Action = '系统操作-互换'
+ORDER BY id;
+-- 记下这些 id（比如 id 列表 = 1001, 1002）
+
+-- 步骤2：对该交易日执行重收盘（前端操作或调 SwapPositionCompose）
+
+-- 步骤3：盘后再查同样的 id
+SELECT id, TradeId, Action, Money
+FROM ClientCashInCashOut
+WHERE id IN (1001, 1002);  -- 替换为步骤1记下的 id
+```
+
+**判断标准**：
+- **修复前（bug）**：步骤3 查不到记录（被 `RemoveRange` 删除）。
+- **修复后（正确）**：步骤3 记录原样存在（id/Money/OptName 不变）。
+
+### 自测 2：守恒校验（验证没修过头 → 自动互换仍能清理）
+
+确保修复后**自动互换的重复资金记录仍被清理**，否则"每次收盘多出一条"老 bug 复发：
+
+```sql
+-- 对一笔纯自动互换交易，连续重收盘 3 次，每次收盘后查记录数
+SELECT COUNT(*) AS cnt
+FROM ClientCashInCashOut
+WHERE TradeId = <自动互换交易ID>
+  AND Action IN ('系统操作-互换', '系统操作-预付金返息')
+  AND HappenDate >= '<收盘日>';
+```
+
+**判断**：连跑 3 次后 `cnt` 应**稳定不变**（每次清掉重算），**不应**线性递增（若递增说明自动互换资金漏删，老 bug 复发）。
+
+### 自测 3：录制测试（复用已有 golden 模式，可进回归）
+
+参考本仓库 `UnitTestProject/Modules/SwapModule/SwapDividendGoldenRecordTest.cs` 的录制模式（连真实测试库 `192.168.2.96/glms_yltrs_ylcms`），骨架：
+
+```csharp
+[Ignore] // 有写副作用，标 Ignore 不进 CI；手动跑
+[TestCategory("DBRecording")]
+public void ReEod_ShouldNotDeleteManualSwapCashRecord()
+{
+    int tradeId = <有手动互换的交易ID>;
+    DateTime settleDate = <收盘日>;
+
+    using var ctx = DbContextFactory.GetYLDbContext();
+
+    // 盘前快照：手动互换资金记录 id
+    var manualCashIds = ctx.ClientCashInCashOut
+        .Where(x => x.TradeId == tradeId
+                 && x.Action == ClientCashInCashOut.系统操作_互换
+                 && x.HappenDate >= settleDate)
+        .Select(x => x.id).ToList();
+    Console.WriteLine($"盘前手动互换资金记录数: {manualCashIds.Count}");
+
+    // 触发重收盘
+    var service = new SwapEodPositionService(userInfo);
+    service.SwapPositionCompose(settleDate, preSettleDate, new List<int>{ clientId });
+
+    // 盘后验证：手动互换记录必须原样保留
+    var survivors = ctx.ClientCashInCashOut
+        .Where(x => manualCashIds.Contains(x.id)).ToList();
+    Assert.AreEqual(manualCashIds.Count, survivors.Count,
+        "手动互换资金记录不应被重收盘删除");
+}
+```
+
+---
+
+## 九、团队决策问题
+
+1. **选哪个方案？** 推荐方案 A（最小改动+治本），但需先确认 `swap_flow_event.ClientCashId` 在自动互换路径的赋值完整性。方案 B 需数据库迁移，方案 C 适合长期。
+
+2. **历史被误删的数据怎么办？** 若生产已发生"手动互换资金记录被重收盘删除"，是否需要从 `clientcashincashout_history`（`YLContext.cs:127`）或备份恢复？需业务确认影响范围。
+
+3. **是否补单测兜底？** 当前 Swap 模块缺少"重收盘不误删手动数据"的单测，建议补自测 3 的录制测试进回归，防止 `44e89726` 类问题复发。
