"""白话层（docs/design/normal-user-apps.md N10，app/plain.py）和反问收尾的服务端部分（N11、G6）。

- 覆盖：代码里出现的问题编号（工作流发布门禁 contract.* / governed.* / action.* / process.*、子工作流和口径卡固定的版本、
  应用检查 app.*、蓝图 bp.*、模板 tpl.*、个人应用 personal.*、发布单 plan.*）都要有白话。B1、B3、B4 新增的编号由各包
  自己补；这里扫的是代码里实际出现的全部编号，报出没有白话的那几个；
- 谁来改（who）：要管理员的编号 → admin；自动修复给的是 choice → you，auto / assist → assistant；应用检查只有人能处理的
  （APP_HUMAN_ONLY）→ you，其余 → assistant。白话里登记的那一档和这条规则一致（一种说法，P5）；
- 文案：白话里不写「钉住」、不裸写配置键名（check-copy 同一套规则在 scripts/check-copy.mjs 里扫）；
- 反问收尾：只问不改的一轮记进历史时，下一轮的上下文写「助手反问了什么」，不写「没有结果」；只问了一句的那一轮记的
  空图不算「上一轮的图」。
