+ *       (shiftDecimal / roundDecimal / multiplyDecimal / getRule / format /
+ *       roundForSubmit) 一直只有间接覆盖。精度即资损，这里用 golden 值冻结现状：
+ *         1. 全部走字符串数位运算，绕开 IEEE754 浮点陷阱(0.1*0.2、1.005.toFixed)；
+ *         2. roundDecimal 是【绝对值上四舍五入】= AwayFromZero，与 unwindBondCalc
+ *            的 ExitYtm 约定同向；
+ *         3. roundDecimal 不补零(1.2 → '1.2')，补零是 formatCommon/formatFixed 的职责；
+ *         4. roundDecimal 对非法输入/负精度【原样返回不归一】，调用方别拿它当校验器；
+ *         5. getRule 的覆盖优先级：先查 defaults 有无该品种(没有直接 null)，再看
+ *            main.swapPricePrecision 覆盖，覆盖非法则回落 defaults。
+ *
+ * 做法：直接 require 源文件（jest v8 覆盖率据此插桩，readFileSync+new Function
+ *       的沙箱加载会让覆盖率统计看不见）；配置覆盖用 global.main.swapPricePrecision
+ *       注入——模块内 global 绑定到 globalThis，与本测试文件的 global 同源，

+ * unwindLegSign.js — 平仓页收付方向符号（纯函数）
+ * ============================================================================
+ * 把散落在 unwindSwapTrade.js 各计算式里的裸三元（xxx==1 ? ±1 : ∓1）显式化为命名函数。
+ * 【为什么必须显式化】利息盈亏与保证金返还本金对同一 InterestDirection 枚举符号相反——
+ * 这是业务事实而非笔误，任何"顺手统一"都会翻转保证金返还方向（资损级 bug）：
+ *   利息盈亏（利息腿/保证金腿通用，changeInterestAmount 对两类行都生效）：
+ *           收益互换中买方为持有标的向交易商融资，利息=融资成本（买方付出去的钱），
+ *           InterestDirection==1(收取) → 盈亏记 +1；
+ *   保证金返还本金：保证金是客户自己交的抵押金，返息/返还本金是把客户自己的钱退回来，
+ *           本金流方向与利息（成本）相反 → 同枚举符号取镜像 -1。
+ *
+ * 其余两个符号：PayDirection==1(浮动端收取) → +1；PositionType==1(多头) → +1。
+ *
+ * 加载：浏览器 script 标签（先于 unwindSwapTrade.js）；Node：module.exports 供 jest。
