-# 班级 QQ 群监控
-
-只读接收 NapCat OneBot 11 群消息，先持久化到 SQLite，再调用 OpenAI-compatible
-LLM 分析重要度、摘要、行动项和准备物品，最后通过独立的 `notify-gateway`
-发送 Telegram/企业微信即时通知和分群日报。
-
-## 主要行为
-
- 仅处理 `target_group_ids` 白名单中的群，不包含任何 QQ 发消息 action。
- 支持教师账号白名单和按群排除机器人账号。
- 纯确认、寒暄和表情在本地标记为零重要度回执，不调用 LLM、不通知、不进入日报。
- 家长问句固定为重要度 1；可能需要家长行动但信息不完整时至少为 1。
- 周一至周六 19:00 汇总当天；周日 19:00 合并周五至周日并按群生成周末总结。
- 文本即时通知直接显示原文；图片等媒体消息显示 LLM 摘要并发送图片预览。
-
-## 启动
-
-1. 复制 `.env.example` 为 `.env` 并填写环境变量。
-2. 复制 `config.example.yaml` 为 `config/config.yaml`，配置群白名单、教师账号和通知渠道。
-3. 创建共享网络：`docker network create shared-services`。若使用其他名称，设置 `SHARED_NETWORK_NAME`。
-4. 运行 `docker compose up -d --build`。
-5. 打开 NapCat WebUI 登录 QQ，并配置反向 WebSocket：
-   `ws://class-monitor:8765/onebot/v11/ws`，Token 与 `ONEBOT_ACCESS_TOKEN` 一致。
-
-健康接口为 `GET http://127.0.0.1:8765/health`。生产配置、`.env`、数据库、
-日志、媒体缓存和 NapCat 登录数据都被 `.gitignore` 排除。
-
-## 测试
-
-```bash
-docker run --rm --network none -e PYTHONPATH=/app \
-  -v "$PWD/tests:/tests:ro" class-qq-monitor:local python /tests/run_tests.py
-```

-# notify-gateway
-
-独立、可复用的 HTTP 通知网关。调用方必须显式指定渠道；Telegram 还必须指定命名 BOT。
-当前支持 Telegram、企业微信群 Webhook，并保留默认关闭的 OneBot QQ 适配器。
-
-## API
-
-```http
-POST /send
-Authorization: Bearer $NOTIFY_GATEWAY_TOKEN
-Content-Type: application/json
-```
-
-```json
-{
-  "title": "通知标题",
-  "text": "正文",
-  "channels": ["telegram", "wecom_webhook"],
-  "telegram_bot": "default",
-  "idempotency_key": "caller:event:123"
-}
-```
-
-可选 `images` 接受最多 4 张 JPEG/PNG Base64 图片，原始数据合计不超过 50 MB：
-
-```json
-{"images":[{"filename":"photo.jpg","content_type":"image/jpeg","data_base64":"..."}]}
-```
-
- Telegram：尺寸允许时直接以照片显示，过大时只发送压缩照片预览。
- 企业微信：尺寸允许时直接显示，过大时只发送不超过平台限制的压缩预览。
- 网关不再把原图作为文件附件发送，也不接受远程图片 URL。
- 空标题表示原样纯文本模式，不自动添加 emoji 或分割线。
- `channels` 必须显式指定且不能为空。
- 请求 Telegram 时必须提供配置中存在的 `telegram_bot`。
- 建议始终提供稳定的 `idempotency_key`，成功渠道在重试时会跳过。
- `GET /health` 无需鉴权。
-
-## 启动
-
-1. 复制 `.env.example` 为 `.env` 并填写所需渠道变量。
-2. 复制 `config.example.yaml` 为 `config/config.yaml`，按需启用渠道和命名 BOT。
-3. 创建共享网络：`docker network create shared-services`，或设置 `SHARED_NETWORK_NAME`。
-4. 运行 `docker compose up -d --build`。
-
-Python 调用客户端见 `notifiers/client.py`。
