+## Admin Data Tools
+
+- Admin Data Tools 用于在管理端导出、导入和清空指定 Wiki 内容域数据。
+- Data Tools 只支持固定业务范围，不提供任意 SQL、任意表名输入或网页数据库控制台能力。
+- 权限：
+  - `admin.data.export`：可导出内容数据 bundle。
+  - `admin.data.import`：可导入内容数据 bundle，并可执行 Wipe。
+- 初始默认只有 `owner` 拥有 Data Tools 权限；如需开放给其他角色，必须通过权限管理显式授予。
+- Data Tools 支持范围：
+  - Pokemon
+  - Habitats
+  - Items
+  - Recipes
+  - Daily CheckList
+- Items 与 Recipes 存在依赖关系；选择 Items 进行导出、导入或 Wipe 时，系统必须自动同时纳入 Recipes，前端确认内容也必须显示 Recipes。
+- Wipe 行为：
+  - 删除所选范围的主数据、关联数据、实体翻译、编辑历史、图片上传记录和实体讨论评论。
+  - Wipe Pokemon 会删除 Pokemon 及其属性 / 特长 / 喜欢的东西 / 掉落关联，并移除栖息地中的 Pokemon 出现配置，但不删除栖息地本身。
+  - Wipe Habitats 会删除栖息地、栖息地配方项和 Pokemon 出现配置，但不删除 Pokemon、Items 或 Maps。
+  - Wipe Items 会先删除 Recipes，再删除物品、物品入手方式 / 喜欢的东西关联、栖息地配方项和 Pokemon 掉落关联。
+  - Wipe Recipes 会删除材料单、材料项和入手方式关联，但不删除 Items。
+  - Wipe Daily CheckList 会删除清单任务和任务翻译 / 编辑历史。
+  - 对被清空的 identity 主表重置自增 ID；Pokemon 内部 ID 不是 identity，自定义 / 活动 Pokemon 的系统分配区间仍按当前数据库最大值继续。
+- Export 行为：
+  - 导出为版本化 JSON bundle，包含 `version`、`exportedAt`、`scopes` 和对应范围数据。
+  - JSON bundle 用于系统导入，不作为前台展示内容。
+  - 导出包含所选范围的主数据、关联数据、实体翻译、编辑历史、图片上传记录和实体讨论评论。
+  - 导出必须包含对应 Wipe 会移除的跨范围关联行，例如 Pokemon 出现配置、Pokemon 掉落和栖息地配方项；导入这些关联时，引用的另一侧实体必须已存在。
+  - JSON 不包含上传文件本身；`backend_uploads` volume 需要单独备份。
+- Import 行为：
+  - 当前只支持 Replace selected scopes：导入前先 Wipe bundle 中包含的范围，再在同一事务中还原 bundle 数据。
+  - Import 不自动覆盖系统配置、语言、用户、角色、权限、系统文案或 Life 内容。
+  - 导入数据引用的 System config、Languages、Users 或上传文件路径必须已存在；缺失依赖会导致导入失败并回滚。
+  - Import 完成后重置相关 identity sequence 到当前最大 ID 之后。
+  - 前端导入和 Wipe 必须使用确认 Modal，并要求输入固定确认词后才能执行。

+- 更新信息来源为公开 Gitea 仓库 `https://git.tootaio.com/Kingsmai/pokopiawiki.tootaio.com`。
+- 前端不得直接读取 Gitea API；后端通过 `GET /api/project-updates` 代理并净化公开仓库数据。
+- 项目更新 API 只返回展示所需字段：
+  - 仓库：`name`、`fullName`、公开仓库 `url`、`defaultBranch`、`updatedAt`。
+  - 最近提交分页：`items`、`nextCursor`、`hasMore`；每条提交只包含 `sha`、`shortSha`、提交标题 `title`、完整提交消息 `message`、`createdAt`、不含邮箱的 `authorName`、公开提交 `url`。
+  - 发布版本：`tagName`、`name`、`publishedAt`、公开发布 `url`。
+- 最近提交支持 `limit` 和不透明 `cursor` 增量读取；前端不得依赖 Gitea 的 `page` / `limit` 实现细节。
+- 项目更新 API 不返回 Gitea token、用户邮箱、内部 API URL、内网地址、文件列表、提交统计、Actions 日志、构建日志或调试字段。
+- Home 首页默认展示最近提交预览；用户可通过 View All 进入 `/project-updates` 完整页面。
+- `/project-updates` 按 Life Post 相同的增量方式继续显示更多提交。
+- `/project-updates` 的每条提交默认折叠，仅展示标题、短 SHA、作者和时间；用户可展开单条提交查看完整 Commit Message，并可再次收起。
+- 若仓库后续提供 Release，可展示发布版本。没有 Release 时不展示空发布区块。
