// 每一步都断言账本/战况表/目标计数，覆盖正常流程与异常分支。
//
// 走的是这些生产入口：
//
//	op36 区域移动      handleTownSetUserArea         （含移动后的遭遇/进图那一段）
//	op1511 BOSS 机制   handleRuntimeFiendWarBoss
//	op42 放弃/撤退     handleDungeonGiveupGame（及战况表撤退的整队通道）
//	名册/编制          handleOnlineRaidCommand 之外，编制移动走 moveRuntimeRaidMember
//	副本生命周期       applyRuntimeRaidDungeonLifecycleEvent（selected/loaded/completed）
//	结算与翻牌         applyRuntimeRaidJoinedSquadClear / autoFlipRuntimeRaidPendingCards
//
// 每个客户端 = 一个 gameSession（真 PVF 的城镇/区域/副本数据 + 内存仓库）。
