+/**
+ * closePercentInterestRefresh.test.js — 部分平仓比例变更触发利息腿刷新守卫
+ * ============================================================================
+ * 目的：验证用户从「全部平仓」切换到「部分平仓」并修改比例时，
+ *   getInterestList() 被调用且传递的 closePercent 值是正确的（口径A）。
+ *
+ * 测试策略：
+ *   1. 源码守卫（wiring guard）：读 unwindSwapTrade.js 源码文本，断言关键方法
+ *      在比例变更后确实调用 getInterestList()。
+ *   2. 行为模拟（behavior mock）：在 vm sandbox 中加载 unwindSwapTrade.js，
+ *      mock main.post 捕获 postData，验证不同 closePercent 值被正确传递。
+ * ============================================================================
