PlayerStats 只负责加载定义、持有加成列表、把公式结果写进静态类型裸字段， 不含任何公式（公式在 AttributeFormula）。读取端零开销以满足热路径纪律 （move_speed 每物理帧被 player_manager 读）。 armor/resistance 零消费方且不在 numerical_design §1.1 权威属性表内，属实现 先于设计的残留，删除；真要做玩家侧减伤时按货架 C 属性词条立项（见 spec §2.6）。 hp_max/cpu_limit 现为派生值，从存档字段移除——回读会覆盖公式结果。 旧存档相应键忽略即可，无需提升 schema 版本（hp_max 全项目从无写入方、 cpu_limit 从未被读取）。 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
