 账号、加密后的公共数据 Token、平台模型 API Key、生辰资料、行情快照和复盘数据均在
 `data/review.db`。解密密钥来自 `.env` 中的 `APP_ENCRYPTION_KEY`。数据库与
 密钥必须成对备份，任意一个丢失都无法恢复账号内的加密资料。
 
-问天静态知识文件：
-
-- `data/iching_zh.json`、`data/heaven_knowledge.json` 纳入 Git 与镜像构建；
-  `.dockerignore` 不排除这两个文件（只排除 `data/*.db`、`data/cache/` 等运行时产物）。
-- Compose 把宿主机 `./data` 整目录挂到 `/app/data`，会遮盖镜像里同路径文件。
-  因此宿主机 `data/` 应保留上述两个 JSON；若只缺 `heaven_knowledge.json`，
-  服务会回退读取镜像内
-  `backend/features/heaven/assets/heaven_knowledge.json`，解势仍可用。
-- 持久化位置：正式环境以宿主机项目目录下的 `./data/heaven_knowledge.json` 为准；
-  补文件后无需改代码，重启容器即可加载。
-
 管理员私有的问师 Skill 保存在宿主机 `data/private-mentor-skills/`。该目录随 `data`
 挂载进入容器，但被 Git 与 Docker 构建上下文排除，不会进入 Gitea 或镜像。私有 Skill
 只对管理员账号返回和开放调用，也会随本指南的 `data` 备份一起保存。
