Occupation.fs（Kind/Profile/State + 农夫/渔夫/货郎/书生 中文名常量，按设计 §1 表给初始 Money/Energy/Inventory）；ItemKind 扩出 Fish/Spice/Scroll（basePrice 分支补齐，Food 10.0f 数值路径不变 → 无职业 digest 不动）；WorldBootstrap.initialWorldWithOccupation 默认 None = 旧行为（Money/Energy 覆盖，库存字段先留数据侧、物理挂接留交易单——取舍见 design §2-C 反对加字段）；WorldSave: v3 头仅在有职业时写入（保存 saveToFileWith / loadFromFileWith，v1/v2/v3 无职业类型默认，token 顺序 version|w|h|kind|task|story|…），默认路径 save 输出逐字节等同现行 v2；P10 测试 5 例（§1 表值、v3 round-trip、v1/v2 不吞档、双 seed 逐字节、中文名）；Kernel.Tests 引用 Desktop 以驱动 WorldBootstrap（取舍：不做测试专用 shim）。TaskToken/StoryStage 为 v3 占位（任务系统后续单实现）。
