Root cause: static HashSet跨测试/跨变体污染+硬编码名→编码映射 Changes: - WildcardRegistry: 实例级wildcard管理(IsWildcard/CountWildcards/Clone) - GameState: 新增Wildcards属性(含Clone) - MahjongTile: 移除static_wildcards,IsWildcard仅查编码50-59 +ToString(tile,wildcards)重载用于游戏上下文显示 - MeldsSolver: _wildcards字段→构造函数注入(WildcardRegistry?) - PhaseMachine: _wildcards字段+构造注入 - Deal(): State.Wildcards.Clear()+AddRange替代static ConfigureWildcards +NameToEncoding查表替代switch硬编码 - RandomMahjongAI/HumanMahjongPlayer: state.Wildcards替代static调用 - HumanMahjongPlayer.CheckTing: 补wildcardCount参数(之前遗漏) - ExecuteWinClaim: IsFinished=true→Settle()(之前Phase漏设) Test: CoreTests清理ConfigureWildcards()→WildcardRegistry测试 Impact: 零static state→不同变体/测试完全隔离,未来支持随机宝牌
