只存次数不存加成——加成是派生物，回读时经 _apply_attr_purchases 重建。 这也躲开了 E3-① 记录的坑：_modifiers 是 Array[Dictionary]，而 JSON 回读的 无类型 Array 直接 = 赋值是运行时类型错误，必须 .assign()；存派生源头则不涉及。 回读顺序：attr_purchases 必须早于 load_save_data。后者设 hp，而重建加成会经 _recompute_attrs 触发 hp = minf(hp, hp_max)；顺序颠倒会拿未加成的 hp_max 去钳， 静默吞血（hp_max 可买到 180 后即可复现）。 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

## ProfileManager — 局内 Run 存档 A/B 双槽（Autoload: ProfileManager）
|
||
## 权威来源：architecture_design.md ADR-A2
|
||
## 下面实现了：
|
||
## - A/B 双槽交替写入防崩溃
|
||
## - schema_version 字段必须
|
||
## - 所有读取必须经过 _migrate_run()
|
||
## - NOTIFICATION_WM_CLOSE_REQUEST 尽力写最后一笔
