 - 最长持有期使用9月11日，买后3个交易日保护使用最新买入日9月14日，保护优先于最长持有退出。
 - 整段引擎换股：旧股较早买入100股、已有新股较晚买入100股，旧股按2倍换成新股200股。随后卖200股先扣旧来源，留下新买100股；不重置开仓/最近买入日，成交来源及换股事件保留，已实现不含费用盈亏200。
 - 整段平台表达式：真实手工两买一卖、次日送转、3日买后保护/卖后禁买、16日至17日显式锁定、最长持有退出同时配置。14日至15日审计分别记录保护和禁买，16日至17日记录锁定；18日只生成一笔卖200股、5元的最长持有退出，不重复附加显式卖单。三笔手工来源保留、不计出入金，旧股转成200股后计时不重置。
+- 同一整段测试另验16日锁定期间的已确认手工卖出200股：与14日保护期间卖100股两个变体分别验证。前者15日送转后400股，手工卖出后200股；两个变体最终都在18日仅自动退出剩余200股。锁定仍阻止自动交易，不阻止已授权手工事实入账；T+1未绕过，买后保护和卖后禁买分别沿实际日期计算。
 
 本机Core889、Trading625、Runner460/API127通过，ignore另计；针对性完整审计断言另行通过。两次测试编写阶段的私有方法/辅助函数名编译错误已修正，不计作框架失败或通过证据。不是实际Source或GT交易验收。
