test(refactor): SwapInterestScenario3And4 诚实化——去掉 return 0m, 从交易开始日逐日真实收盘
- 删除 StubSwapDealService.GetConsumedInterest 的 硬编码(此前注释明写"与生产缺陷态一致",
等于把唯一会出错的机制整个屏蔽, 断言缺陷态输出, 伪绿)。
- 改为复用生产同一口径: 对真实收盘经 PersistFlowEvent 累积的 swap_flow_event
(EventType∈{互换,自动互换}, DataState=完成, EventDate<结算日) 求和 —— 数据来自真实代码执行, 非硬编码。
- TestableSwapEodPositionService 新增 FlowEvents 捕获 + override PersistFlowEvent, 供 GetConsumedInterest 真实计算(不连库)。
- 新增 E2EEodService: 从交易开始日(TradeDate)逐日驱动真实 SwapPositionCompose 构建 eod 链,
再把真实 eod 快照喂给平仓; 平仓走生产同一入口 SaveAutoEodWithCloseInterestPosition。
- 全程无硬编码输入: FR007 曲线/名义本金/日期均来自 Excel 场景真源, 计算全走真实代码。
- 验证: 24/24 通过(SKIP_INITIALIZATION); PrepaidPrincipal 追踪测试 2/2 通过; 基类改动无回归。
- 注: ConsumedInterestScenarioTest.CI_008 既有失败(复利重置日本金继承, 与本回合无关, 未触碰该文件), 另议。
