chore(custom-ruleset): Update custom ruleset definitions (#105)

New configurations:

- `CHECK_CLIENT_VERSION` enables the check (default=True)
- `CLIENT_VERSION_URLS` contains a chain of valid client hashes. [osu!](https://osu.ppy.sh/home/download) and [osu! GU](https://github.com/GooGuTeam/osu/releases) are valid by default. View [g0v0-client-versions](https://github.com/GooGuTeam/g0v0-client-versions) to learn how to support your own client.

+# copilot-instruction
+
+> 此文件是 AGENTS.md 的复制。一切以 AGENTS.md 为主。
+
+> 使用自动化与 AI 代理（GitHub Copilot、依赖/CI 机器人，以及仓库中的运行时调度器/worker）的指导原则，适用于 g0v0-server 仓库。
+
+---
+
+## API 参考
+
+本项目必须保持与公开的 osu! API 兼容。在添加或映射端点时请参考：
+
+- **v1（旧版）：** [https://github.com/ppy/osu-api/wiki](https://github.com/ppy/osu-api/wiki)
+- **v2（OpenAPI）：** [https://osu.ppy.sh/docs/openapi.yaml](https://osu.ppy.sh/docs/openapi.yaml)
+
+任何在 `app/router/v1/`、`app/router/v2/` 或 `app/router/notification/` 中的实现必须与官方规范保持一致。自定义或实验性的端点应放在 `app/router/private/` 中。
+
+---
+
+## 代理类别
+
+允许的代理分为三类：
+
+- **代码生成/补全代理**（如 GitHub Copilot 或其他 LLM）—— **仅当** 有维护者审核并批准输出时允许使用。
+- **自动维护代理**（如 Dependabot、Renovate、pre-commit.ci）—— 允许使用，但必须遵守严格的 PR 和 CI 政策。
+- **运行时/后台代理**（调度器、worker）—— 属于产品代码的一部分；必须遵守生命周期、并发和幂等性规范。
+
+所有由代理生成或建议的更改必须遵守以下规则。
+
+---
+
+## 所有代理的规则
+
+1. **单一职责的 PR。** 代理的 PR 必须只解决一个问题（一个功能、一个 bug 修复或一次依赖更新）。提交信息应使用 Angular 风格（如 `feat(api): add ...`）。
+2. **通过 Lint 与 CI 检查。** 每个 PR（包括代理创建的）在合并前必须通过 `pyright`、`ruff`、`pre-commit` 钩子和仓库 CI。PR 中应附带 CI 运行结果链接。
+3. **绝不可提交敏感信息。** 代理不得提交密钥、密码、token 或真实 `.env` 值。如果检测到可能的敏感信息，代理必须中止并通知指定的维护者。
+4. **API 位置限制。** 不得在 `app/router/v1` 或 `app/router/v2` 下添加新的公开端点，除非该端点在官方 v1/v2 规范中存在。自定义或实验性端点必须放在 `app/router/private/`。
+5. **保持公共契约稳定。** 未经批准的迁移计划，不得随意修改响应 schema、路由前缀或其他公共契约。若有变更，PR 中必须包含明确的兼容性说明。
+
+---
+
+## Copilot / LLM 使用
+
+> 关于在本仓库中使用 GitHub Copilot 和其他基于 LLM 的辅助工具的统一指导。
+
+### 关键项目结构（需要了解的内容）
+
+- **应用入口：** `main.py` —— FastAPI 应用，包含启动/关闭生命周期管理（fetchers、GeoIP、调度器、缓存与健康检查、Redis 消息、统计、成就系统）。
+
+- **路由：** `app/router/` 包含所有路由组。主要的路由包括：
+  - `v1/`（v1 端点）
+  - `v2/`（v2 端点）
+  - `notification/` 路由（聊天/通知子系统）
+  - `auth.py`（认证/token 流程）
+  - `private/`（自定义或实验性的端点）
+
+  **规则：** `v1/` 和 `v2/` 必须与官方 API 对应。仅内部或实验端点应放在 `app/router/private/`。
+
+- **模型与数据库工具：**
+  - SQLModel/ORM 模型在 `app/database/`。
+  - 非数据库模型在 `app/models/`。
+  - 修改模型/schema 时必须生成 Alembic 迁移，并手动检查生成的 SQL 与索引。
+
+- **服务层：** `app/service/` 保存领域逻辑（如缓存工具、通知/邮件逻辑）。复杂逻辑应放在 service，而不是路由处理器中。
+
+- **任务：** `app/tasks/` 保存任务（定时任务、启动任务、关闭任务）。
+  - 均在 `__init__.py` 进行导出。
+  - 对于启动任务/关闭任务，在 `main.py` 的 `lifespan` 调用。
+  - 定时任务使用 APScheduler
+
+- **缓存与依赖：** 使用 `app/dependencies/` 提供的 Redis 依赖和缓存服务（遵循现有 key 命名约定，如 `user:{id}:...`）。
+
+- **日志：** 使用 `app/log` 提供的日志工具。
+
+### 实用工作流（提示模式）
+
+- **添加 v2 端点（正确方式）：** 在 `app/router/v2/` 下添加文件，导出路由，实现基于数据库与缓存依赖的异步处理函数。**不得**在 v1/v2 添加非官方端点。
+- **添加自定义端点：** 放在 `app/router/private/`，保持处理器精简，将业务逻辑放入 `app/service/`。
+- **鉴权：** 使用 [`app.dependencies.user`](../app/dependencies/user.py) 提供的依赖注入，如 `ClientUser` 和 `get_current_user`，参考下方。
+  
+  ```python
+  from typing import Annotated
+  from fastapi import Security
+  from app.dependencies.user import ClientUser, get_current_user
+
+
+  @router.get("/some-api")
+  async def _(current_user: Annotated[User, Security(get_current_user, scopes=["public"])]):
+      ...
+
+
+  @router.get("/some-client-api")
+  async def _(current_user: ClientUser):
+      ...
+  ```
+
+- **添加后台任务：** 将任务逻辑写在 `app/service/_job.py`（幂等、可重试）。调度器入口放在 `app/scheduler/_scheduler.py`，并在应用生命周期注册。
+- **数据库 schema 变更：** 修改 `app/models/` 中的 SQLModel 模型，运行 `alembic revision --autogenerate`，检查迁移并本地测试 `alembic upgrade head` 后再提交。
+- **缓存写入与响应：** 使用现有的 `UserResp` 模式和 `UserCacheService`；异步缓存写入应使用后台任务。
+
+### 提示指导（给 LLM/Copilot 的输入）
+
+- 明确文件位置和限制（如：`Add an async endpoint under app/router/private/... DO NOT add to app/router/v1 or v2`）。
+- 要求异步处理函数、依赖注入 DB/Redis、复用已有服务/工具、加上类型注解，并生成最小化 pytest 测试样例。
+
+### 约定与质量要求
+
+- **使用 Annotated-style 依赖注入** 在路由处理器中。
+- **提交信息风格：** `type(scope): subject`（Angular 风格）。
+- **优先异步：** 路由必须为异步函数；避免阻塞事件循环。
+- **关注点分离：** 业务逻辑应放在 service，而不是路由中。
+- **错误处理：** 客户端错误用 `HTTPException`，服务端错误使用结构化日志。
+- **类型与 lint：** 在请求评审前，代码必须通过 `pyright` 和 `ruff` 检查。
+- **注释：** 避免过多注释，仅为晦涩逻辑添加简洁的“魔法注释”。
+- **日志：** 使用 `app.log` 提供的 `log` 函数获取 logger 实例。（服务、任务除外）
+
+### 工具参考
+
+```
+uv sync
+pre-commit install
+pre-commit run --all-files
+pyright
+ruff .
+alembic revision --autogenerate -m "feat(db): ..."
+alembic upgrade head
+uvicorn main:app --reload --host 0.0.0.0 --port 8000
+```
+
+### PR 范围指导
+
+- 保持 PR 专注：一次只做一件事（如端点或重构，不要混合）。
+- 不确定时，请参考现有服务，并添加简短说明性注释。
+
+### PR 审核规则
+
+> GitHub Copilot PR review 可参考。
+
+1. 如果 PR 修改了端点，简要说明端点的用途和预期行为。同时检查是否满足上述的 API 位置限制。
+2. 如果 PR 修改了数据库模型，必须包含 Alembic 迁移。检查迁移的 SQL 语句和索引是否合理。
+3. 修改的其他功能需要提供简短的说明。
+4. 提供性能优化的建议（见下文）。
+
+---
+
+## 性能优化提示
+
+以下为结合本仓库架构（FastAPI + SQLModel/SQLAlchemy、Redis 缓存、后台调度器）总结的性能优化建议：
+
+### 数据库
+
+- **仅选择必要字段。** 使用 `select(Model.col1, Model.col2)`，避免 `select(Model)`。
+
+```py
+stmt = select(User.id, User.username).where(User.active == True)
+rows = await session.execute(stmt)
+```
+
+- **使用 `select(exists())` 检查存在性。** 避免加载整行：
+
+```py
+from sqlalchemy import select, exists
+exists_stmt = select(exists().where(User.id == some_id))
+found = await session.scalar(exists_stmt)
+```
+
+- **避免 N+1 查询。** 需要关联对象时用 `selectinload`、`joinedload`。
+
+- **批量操作。** 插入/更新时应批量执行，并放在一个事务中，而不是多个小事务。
+
+
+### 耗时任务
+
+- 如果这个任务来自 API Router，请使用 FastAPI 提供的 [`BackgroundTasks`](https://fastapi.tiangolo.com/tutorial/background-tasks)
+- 其他情况，使用 `app.utils` 的 `bg_tasks`，它提供了与 FastAPI 的 `BackgroundTasks` 类似的功能。
+
+---
+
+## 部分 LLM 的额外要求
+
+### Claude Code
+
+- 禁止创建额外的测试脚本。

+# AGENTS
+
+> 使用自动化与 AI 代理（GitHub Copilot、依赖/CI 机器人，以及仓库中的运行时调度器/worker）的指导原则，适用于 g0v0-server 仓库。
+
+---
+
+## API 参考
+
+本项目必须保持与公开的 osu! API 兼容。在添加或映射端点时请参考：
+
+- **v1（旧版）：** [https://github.com/ppy/osu-api/wiki](https://github.com/ppy/osu-api/wiki)
+- **v2（OpenAPI）：** [https://osu.ppy.sh/docs/openapi.yaml](https://osu.ppy.sh/docs/openapi.yaml)
+
+任何在 `app/router/v1/`、`app/router/v2/` 或 `app/router/notification/` 中的实现必须与官方规范保持一致。自定义或实验性的端点应放在 `app/router/private/` 中。
+
+---
+
+## 代理类别
+
+允许的代理分为三类：
+
+- **代码生成/补全代理**（如 GitHub Copilot 或其他 LLM）—— **仅当** 有维护者审核并批准输出时允许使用。
+- **自动维护代理**（如 Dependabot、Renovate、pre-commit.ci）—— 允许使用，但必须遵守严格的 PR 和 CI 政策。
+- **运行时/后台代理**（调度器、worker）—— 属于产品代码的一部分；必须遵守生命周期、并发和幂等性规范。
+
+所有由代理生成或建议的更改必须遵守以下规则。
+
+---
+
+## 所有代理的规则
+
+1. **单一职责的 PR。** 代理的 PR 必须只解决一个问题（一个功能、一个 bug 修复或一次依赖更新）。提交信息应使用 Angular 风格（如 `feat(api): add ...`）。
+2. **通过 Lint 与 CI 检查。** 每个 PR（包括代理创建的）在合并前必须通过 `pyright`、`ruff`、`pre-commit` 钩子和仓库 CI。PR 中应附带 CI 运行结果链接。
+3. **绝不可提交敏感信息。** 代理不得提交密钥、密码、token 或真实 `.env` 值。如果检测到可能的敏感信息，代理必须中止并通知指定的维护者。
+4. **API 位置限制。** 不得在 `app/router/v1` 或 `app/router/v2` 下添加新的公开端点，除非该端点在官方 v1/v2 规范中存在。自定义或实验性端点必须放在 `app/router/private/`。
+5. **保持公共契约稳定。** 未经批准的迁移计划，不得随意修改响应 schema、路由前缀或其他公共契约。若有变更，PR 中必须包含明确的兼容性说明。
+
+---
+
+## Copilot / LLM 使用
+
+> 关于在本仓库中使用 GitHub Copilot 和其他基于 LLM 的辅助工具的统一指导。
+
+### 关键项目结构（需要了解的内容）
+
+- **应用入口：** `main.py` —— FastAPI 应用，包含启动/关闭生命周期管理（fetchers、GeoIP、调度器、缓存与健康检查、Redis 消息、统计、成就系统）。
+
+- **路由：** `app/router/` 包含所有路由组。主要的路由包括：
+  - `v1/`（v1 端点）
+  - `v2/`（v2 端点）
+  - `notification/` 路由（聊天/通知子系统）
+  - `auth.py`（认证/token 流程）
+  - `private/`（自定义或实验性的端点）
+
+  **规则：** `v1/` 和 `v2/` 必须与官方 API 对应。仅内部或实验端点应放在 `app/router/private/`。
+
+- **模型与数据库工具：**
+  - SQLModel/ORM 模型在 `app/database/`。
+  - 非数据库模型在 `app/models/`。
+  - 修改模型/schema 时必须生成 Alembic 迁移，并手动检查生成的 SQL 与索引。
+
+- **服务层：** `app/service/` 保存领域逻辑（如缓存工具、通知/邮件逻辑）。复杂逻辑应放在 service，而不是路由处理器中。
+
+- **任务：** `app/tasks/` 保存任务（定时任务、启动任务、关闭任务）。
+  - 均在 `__init__.py` 进行导出。
+  - 对于启动任务/关闭任务，在 `main.py` 的 `lifespan` 调用。
+  - 定时任务使用 APScheduler
+
+- **缓存与依赖：** 使用 `app/dependencies/` 提供的 Redis 依赖和缓存服务（遵循现有 key 命名约定，如 `user:{id}:...`）。
+
+- **日志：** 使用 `app/log` 提供的日志工具。
+
+### 实用工作流（提示模式）
+
+- **添加 v2 端点（正确方式）：** 在 `app/router/v2/` 下添加文件，导出路由，实现基于数据库与缓存依赖的异步处理函数。**不得**在 v1/v2 添加非官方端点。
+- **添加自定义端点：** 放在 `app/router/private/`，保持处理器精简，将业务逻辑放入 `app/service/`。
+- **鉴权：** 使用 [`app.dependencies.user`](./app/dependencies/user.py) 提供的依赖注入，如 `ClientUser` 和 `get_current_user`，参考下方。
+  
+  ```python
+  from typing import Annotated
+  from fastapi import Security
+  from app.dependencies.user import ClientUser, get_current_user
+
+
+  @router.get("/some-api")
+  async def _(current_user: Annotated[User, Security(get_current_user, scopes=["public"])]):
+      ...
+
+
+  @router.get("/some-client-api")
+  async def _(current_user: ClientUser):
+      ...
+  ```
+
+- **添加后台任务：** 将任务逻辑写在 `app/service/_job.py`（幂等、可重试）。调度器入口放在 `app/scheduler/_scheduler.py`，并在应用生命周期注册。
+- **数据库 schema 变更：** 修改 `app/models/` 中的 SQLModel 模型，运行 `alembic revision --autogenerate`，检查迁移并本地测试 `alembic upgrade head` 后再提交。
+- **缓存写入与响应：** 使用现有的 `UserResp` 模式和 `UserCacheService`；异步缓存写入应使用后台任务。
+
+### 提示指导（给 LLM/Copilot 的输入）
+
+- 明确文件位置和限制（如：`Add an async endpoint under app/router/private/... DO NOT add to app/router/v1 or v2`）。
+- 要求异步处理函数、依赖注入 DB/Redis、复用已有服务/工具、加上类型注解，并生成最小化 pytest 测试样例。
+
+### 约定与质量要求
+
+- **使用 Annotated-style 依赖注入** 在路由处理器中。
+- **提交信息风格：** `type(scope): subject`（Angular 风格）。
+- **优先异步：** 路由必须为异步函数；避免阻塞事件循环。
+- **关注点分离：** 业务逻辑应放在 service，而不是路由中。
+- **错误处理：** 客户端错误用 `HTTPException`，服务端错误使用结构化日志。
+- **类型与 lint：** 在请求评审前，代码必须通过 `pyright` 和 `ruff` 检查。
+- **注释：** 避免过多注释，仅为晦涩逻辑添加简洁的“魔法注释”。
+- **日志：** 使用 `app.log` 提供的 `log` 函数获取 logger 实例。（服务、任务除外）
+
+### 工具参考
+
+```
+uv sync
+pre-commit install
+pre-commit run --all-files
+pyright
+ruff .
+alembic revision --autogenerate -m "feat(db): ..."
+alembic upgrade head
+uvicorn main:app --reload --host 0.0.0.0 --port 8000
+```
+
+### PR 范围指导
+
+- 保持 PR 专注：一次只做一件事（如端点或重构，不要混合）。
+- 不确定时，请参考现有服务，并添加简短说明性注释。
+
+### PR 审核规则
+
+> GitHub Copilot PR review 可参考。
+
+1. 如果 PR 修改了端点，简要说明端点的用途和预期行为。同时检查是否满足上述的 API 位置限制。
+2. 如果 PR 修改了数据库模型，必须包含 Alembic 迁移。检查迁移的 SQL 语句和索引是否合理。
+3. 修改的其他功能需要提供简短的说明。
+4. 提供性能优化的建议（见下文）。
+
+---
+
+## 性能优化提示
+
+以下为结合本仓库架构（FastAPI + SQLModel/SQLAlchemy、Redis 缓存、后台调度器）总结的性能优化建议：
+
+### 数据库
+
+- **仅选择必要字段。** 使用 `select(Model.col1, Model.col2)`，避免 `select(Model)`。
+
+```py
+stmt = select(User.id, User.username).where(User.active == True)
+rows = await session.execute(stmt)
+```
+
+- **使用 `select(exists())` 检查存在性。** 避免加载整行：
+
+```py
+from sqlalchemy import select, exists
+exists_stmt = select(exists().where(User.id == some_id))
+found = await session.scalar(exists_stmt)
+```
+
+- **避免 N+1 查询。** 需要关联对象时用 `selectinload`、`joinedload`。
+
+- **批量操作。** 插入/更新时应批量执行，并放在一个事务中，而不是多个小事务。
+
+
+### 耗时任务
+
+- 如果这个任务来自 API Router，请使用 FastAPI 提供的 [`BackgroundTasks`](https://fastapi.tiangolo.com/tutorial/background-tasks)
+- 其他情况，使用 `app.utils` 的 `bg_tasks`，它提供了与 FastAPI 的 `BackgroundTasks` 类似的功能。
+
+---
+
+## 部分 LLM 的额外要求
+
+### Claude Code
+
+- 禁止创建额外的测试脚本。

+# 贡献指南
+
+## 克隆项目
+
+```bash
+git clone https://github.com/GooGuTeam/g0v0-server.git
+```
+
+此外，您还需要：
+
+- clone 旁观服务器到 g0v0-server 的文件夹。
+
+```bash
+git clone https://github.com/GooGuTeam/osu-server-spectator.git spectator-server
+```
+
+- clone 表现分计算器到 g0v0-server 的文件夹。
+
+```bash
+git clone https://github.com/GooGuTeam/osu-performance-server.git performance-server
+```
+
+- 下载并放置自定义规则集 DLL 到 `rulesets/` 目录（如果需要）。
+
+## 开发环境
+
+为了确保一致的开发环境，我们强烈建议使用提供的 Dev Container。这将设置一个容器化的环境，预先安装所有必要的工具和依赖项。
+
+1. 安装 [Docker](https://www.docker.com/products/docker-desktop/)。
+2. 在 Visual Studio Code 中安装 [Dev Containers extension](https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.remote-containers)。
+3. 在 VS Code 中打开项目。当被提示时，点击“在容器中重新打开”以启动开发容器。
+
+## 配置项目
+
+修改 `.env` 配置（参考 [wiki](https://github.com/GooGuTeam/g0v0-server/wiki/Configuration)），生成并填充 JWT 密钥。
+
+如果在 Dev Container 运行，请修改 `MYSQL_HOST` 为 `mysql`，`REDIS_URL` 为 `redis://redis/0`。
+
+## 启动项目
+
+.devcontainer 文件夹提供了一个启动脚本 `start-dev.sh`，这个脚本会从 `.env` 加载环境变量并同时启动 g0v0-server（端口 `8000`）和 spectator-server（端口 `8006`）。
+
+Dev Container 提供了 NGINX 进行转发，对外访问端口是 `8080`。
+
+如果您的服务器没有配置 HTTPS，可以在启动 osu! 的时候指定环境变量 `OSU_INSECURE_REQUESTS=1` 禁用 SSL 检查，或者应用 [osu!lazer wiki](https://github.com/ppy/osu/wiki/Testing-web-server-full-stack-with-osu!#basics) 提供的 diff。
+
+或者使用下方的命令手动启动：
+
+```bash
+# g0v0-server
+uv run uvicorn main:app --host 0.0.0.0 --port 8000 --reload
+# spectator-server
+cd spectator-server
+dotnet run --project osu.Server.Spectator --urls "http://0.0.0.0:8086"
+```
+
+## 依赖管理
+
+使用 `uv` 进行快速高效的 Python 包管理。
+
+要安装依赖项，请在终端中运行以下命令：
+
+```bash
+uv sync
+```
+
+## 开发规范

+
+### 数据库模型定义
+
+所有的数据库模型定义在 `app.database` 里，并且在 `__init__.py` 中导出。
+
+本项目使用一种“按需返回”的设计模式，遵循 `Dict` - `Model` - `Table` 结构。详细设计思路请参考[这篇文章](https://blog.mxgame.top/2025/11/22/An-On-Demand-Design-Within-SQLModel/)。
+
+#### 基本结构
+
+1. **Dict**: 定义模型转换后的字典结构，用于类型检查。必须在 Model 之前定义。
+2. **Model**: 继承自 `DatabaseModel[Dict]`，定义字段和计算属性。
+3. **Table**: 继承自 `Model`，定义数据库表结构。
+
+```python
+from typing import TypedDict, NotRequired
+from app.database._base import DatabaseModel, OnDemand, included, ondemand
+from sqlmodel import Field
+
+# 1. 定义 Dict
+class UserDict(TypedDict):
+    id: int
+    username: str
+    email: NotRequired[str]  # 可选字段
+    followers_count: int     # 计算属性
+
+# 2. 定义 Model
+class UserModel(DatabaseModel[UserDict]):
+    id: int = Field(primary_key=True)
+    username: str
+    email: OnDemand[str]     # 使用 OnDemand 标记可选字段
+
+    # 普通计算属性 (总是返回)
+    @included
+    @staticmethod
+    async def followers_count(session: AsyncSession, instance: "User") -> int:
+        return await session.scalar(select(func.count()).where(Follower.followed_id == instance.id))
+    
+    # 可选计算属性 (仅在 includes 中指定时返回)
+    @ondemand
+    @staticmethod
+    async def some_optional_property(session: AsyncSession, instance: "User") -> str:
+        ...
+
+# 3. 定义 Table
+class User(UserModel, table=True):
+    password: str            # 仅在数据库中存在的字段
+    ...
+```
+
+#### 字段类型
+
+- **普通属性**: 直接定义在 Model 中，总是返回。
+- **可选属性**: 使用 `OnDemand[T]` 标记，仅在 `includes` 中指定时返回。
+- **普通计算属性**: 使用 `@included` 装饰的静态方法，总是返回。
+- **可选计算属性**: 使用 `@ondemand` 装饰的静态方法，仅在 `includes` 中指定时返回。
+
+#### 使用方法
+
+**转换模型**:
+
+使用 `Model.transform` 方法将数据库实例转换为字典：
+
+```python
+user = await session.get(User, 1)
+user_dict = await UserModel.transform(
+    user,
+    includes=["email"],  # 指定需要返回的可选字段
+    some_context="foo-bar",  # 如果计算属性需要上下文，可以传入额外参数
+    session=session      # 可选传入自己的 session
+)
+```
+
+**API 文档**:
+
+在 FastAPI 路由中，使用 `Model.generate_typeddict` 生成准确的响应文档：
+
+```python
+@router.get("/users/{id}", response_model=UserModel.generate_typeddict(includes=("email",)))
+async def get_user(id: int) -> dict:
+    ...
+    return await UserModel.transform(user, includes=["email"])
+```
+
+数据库模块名应与表名相同，定义了多个模型的除外。
+
+如果你需要使用 Session，使用 `app.dependencies.database` 提供的 `with_db`，注意手动使用 `COMMIT`。
+
+```python
+from app.dependencies.database import with_db
+
+async with with_db() as session:
+    ...
+```
+
+### Redis
+
+根据你需要的用途选择对应的 Redis 客户端。如果你的用途较为复杂或趋向一个较大的系统，考虑再创建一个 Redis 连接。
+
+- `redis_client` (db0)：标准用途，存储字符串、哈希等常规数据。
+- `redis_message_client` (db1)：用于消息缓存，存储聊天记录等。
+- `redis_binary_client` (db2)：用于存储二进制数据，如音频文件等。
+- `redis_rate_limit_client` (db3)：仅用于 FastAPI-Limiter 使用。
+
+### API Router
+
+所有的 API Router 定义在 `app.router` 里：
+
+- `app/router/v2` 存放所有 osu! v2 API 实现，**不允许添加额外的，原 v2 API 不存在的 Endpoint**
+- `app/router/notification` **存放所有 osu! v2 API 聊天、通知和 BanchoBot 的实现，不允许添加额外的，原 v2 API 不存在的 Endpoint**
+- `app/router/v1` 存放所有 osu! v1 API 实现，**不允许添加额外的，原 v1 API 不存在的 Endpoint**
+- `app/router/auth.py` 存放账户鉴权/登录的 API
+- `app/router/private` 存放服务器自定义 API (g0v0 API)，供其他服务使用
+
+任何 Router 需要满足：
+
+- 使用 Annotated-style 的依赖注入
+- 对于已经存在的依赖注入如 Database 和 Redis，使用 `app.dependencies` 中的实现
+- 需要拥有文档
+- 如果返回需要资源代理，使用 `app.helpers.asset_proxy_helper` 的 `asset_proxy_response` 装饰器。
+- 如果需要记录日志，请使用 `app.log` 提供的 `log` 函数获取一个 logger 实例
+
+#### 鉴权
+
+如果这个 Router 可以为公开使用（客户端、前端、OAuth 程序），考虑使用 `Security(get_current_user, scopes=["some_scope"])`，例如：
+
+```python
+from typing import Annotated
+from fastapi import Security
+from app.dependencies.user import get_current_user
+
+
+@router.get("/some-api")
+async def _(current_user: Annotated[User, Security(get_current_user, scopes=["public"])]):
+    ...
+```
+
+其中 scopes 选择请参考 [`app.dependencies.user`](./app/dependencies/user.py) 的 `oauth2_code` 中的 `scopes`。
+
+如果这个 Router 仅限客户端和前端使用，请使用 `ClientUser` 依赖注入。
+
+```python
+from app.dependencies.user import ClientUser
+
+
+@router.get("/some-api")
+async def _(current_user: ClientUser):
+    ...
+```
+
+此外还存在 `get_current_user_and_token` 和 `get_client_user_and_token` 变种，用来同时获得当前用户的 token。
+
+### Service
+
+所有的核心业务逻辑放在 `app.service` 里：
+
+- 业务逻辑需要要以类实现
+- 日志只需要使用 `app.log` 中的 `logger` 即可。服务器会对 Service 的日志进行包装。
+
+### 定时任务/启动任务/关闭任务
+
+均定义在 `app.tasks` 里。
+
+- 均在 `__init__.py` 进行导出
+- 对于启动任务/关闭任务，在 `main.py` 的 `lifespan` 调用。
+- 定时任务使用 APScheduler
+
+### 耗时任务
+
+- 如果这个任务来自 API Router，请使用 FastAPI 提供的 [`BackgroundTasks`](https://fastapi.tiangolo.com/tutorial/background-tasks)
+- 其他情况，使用 `app.utils` 的 `bg_tasks`，它提供了与 FastAPI 的 `BackgroundTasks` 类似的功能。
+
+### 代码质量和代码检查
+
+使用 `pre-commit` 在提交之前执行代码质量标准。这确保所有代码都通过 `ruff`（用于代码检查和格式化）和 `pyright`（用于类型检查）的检查。
+
+#### 设置
+
+要设置 `pre-commit`，请运行以下命令：
+
+```bash
+pre-commit install
+```
+
+这将安装 pre-commit 钩子，每次提交时会自动运行。如果任何检查失败，提交将被中止。您需要修复报告的问题并暂存更改，然后再尝试提交。
+
+pre-commit 不提供 pyright 的 hook，您需要手动运行 `pyright` 检查类型错误。
+
+### 提交信息指南
+
+遵循 [AngularJS 提交规范](https://github.com/angular/angular.js/blob/master/DEVELOPERS.md#commit-message-format) 来编写提交信息。
+
+**类型** 必须是以下之一：
+
+- **feat**：新功能
+- **fix**：错误修复
+- **docs**：仅文档更改
+- **style**：不影响代码含义的更改（空格、格式、缺少分号等）
+- **refactor**：代码重构
+- **perf**：改善性能的代码更改
+- **test**：添加缺失的测试或修正现有测试
+- **chore**：对构建过程或辅助工具和库（如文档生成）的更改
+- **ci**：持续集成相关的更改
+- **deploy**: 部署相关的更改
+
+**范围** 可以是任何指定提交更改位置的内容。例如 `api`、`db`、`auth` 等等。对整个项目的更改使用 `project`。
+
+**主题** 包含对更改的简洁描述。
+
+### 持续集成检查
+
+所有提交应该通过以下 CI 检查：
+
+- Ruff Lint
+- Pyright Lint
+- pre-commit
+

+                            Preamble
 
-The above copyright notice and this permission notice shall be included in all
-copies or substantial portions of the Software.
+  The GNU Affero General Public License is a free, copyleft license for
+software and other kinds of works, specifically designed to ensure
+cooperation with the community in the case of network server software.
 
-THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR
-IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY,
-FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT. IN NO EVENT SHALL THE
-AUTHORS OR COPYRIGHT HOLDERS BE LIABLE FOR ANY CLAIM, DAMAGES OR OTHER

-SOFTWARE.
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+our General Public Licenses are intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  Developers that use our General Public Licenses protect your rights
+with two steps: (1) assert copyright on the software, and (2) offer
+you this License which gives you legal permission to copy, distribute
+and/or modify the software.
+
+  A secondary benefit of defending all users' freedom is that
+improvements made in alternate versions of the program, if they
+receive widespread use, become available for other developers to
+incorporate.  Many developers of free software are heartened and
+encouraged by the resulting cooperation.  However, in the case of
+software used on network servers, this result may fail to come about.
+The GNU General Public License permits making a modified version and
+letting the public access it on a server without ever releasing its
+source code to the public.
+
+  The GNU Affero General Public License is designed specifically to
+ensure that, in such cases, the modified source code becomes available
+to the community.  It requires the operator of a network server to
+provide the source code of the modified version running there to the
+users of that server.  Therefore, public use of a modified version, on
+a publicly accessible server, gives the public access to the source
+code of the modified version.
+
+  An older license, called the Affero General Public License and
+published by Affero, was designed to accomplish similar goals.  This is
+a different license, not a version of the Affero GPL, but Affero has
+released a new version of the Affero GPL which permits relicensing under
+this license.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU Affero General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Remote Network Interaction; Use with the GNU General Public License.
+
+  Notwithstanding any other provision of this License, if you modify the
+Program, your modified version must prominently offer all users
+interacting with it remotely through a computer network (if your version
+supports such interaction) an opportunity to receive the Corresponding
+Source of your version by providing access to the Corresponding Source
+from a network server at no charge, through some standard or customary
+means of facilitating copying of software.  This Corresponding Source
+shall include the Corresponding Source for any work covered by version 3
+of the GNU General Public License that is incorporated pursuant to the
+following paragraph.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the work with which it is combined will remain governed by version
+3 of the GNU General Public License.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU Affero General Public License from time to time.  Such new versions
+will be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU Affero General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU Affero General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU Affero General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU Affero General Public License as published
+    by the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU Affero General Public License for more details.
+
+    You should have received a copy of the GNU Affero General Public License
+    along with this program.  If not, see <https://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If your software can interact with users remotely through a computer
+network, you should also make sure that it provides a way for users to
+get its source.  For example, if your program is a web application, its
+interface could display a "Source" link that leads users to an archive
+of the code.  There are many ways you could offer source, and different
+solutions will be better for different programs; see section 13 for the
+specific requirements.
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU AGPL, see
+<https://www.gnu.org/licenses/>.

 ### Updating the Database
 
 Refer to the [Database Migration Guide](https://github.com/GooGuTeam/g0v0-server/wiki/Migrate-Database)
 
+## Security
+
+Use `openssl rand -hex 32` to generate the JWT secret key to ensure the security of the server and the normal operation of the observer server.
+
+Use `openssl rand -hex 40` to generate the frontend secret key.
+
+**If it is in a public network environment, please block external requests to the `/_lio` path.**
