-launchd 会调用 `scripts/run_pipeline.sh`，因此也使用 sibling 项目 `.env` 中的凭据；模板通过 `PYTHON_BIN` 传入 mac2 的 Python 路径，并保留工作目录和 stdout/stderr 日志路径：
+mac2 使用 crontab 定时调用 `scripts/run_pipeline.sh`。包装脚本会读取 sibling 项目 `.env` 中的凭据，因此 cron 环境不需要配置密钥。先确认手工执行成功，再编辑当前用户的 crontab：
 
 ```sh
 cd /Users/shareit./Library/CloudStorage/OneDrive-个人/ubuntu/Gitea/af-click-gap
-mkdir -p "$HOME/Library/Logs/af-click-gap" "$HOME/Library/LaunchAgents"
-PY=$(command -v python3)
-sed -e "s#__MAC2_PYTHON3__#$PY#" -e "s#__PROJECT_DIR__#$PWD#g" -e "s#__LOG_DIR__#$HOME/Library/Logs/af-click-gap#g" launchd/com.roasbloom.af-click-gap.plist.template > /tmp/com.roasbloom.af-click-gap.plist
-plutil -lint /tmp/com.roasbloom.af-click-gap.plist

+crontab -e
 ```
 
-卸载：`launchctl bootout "gui/$(id -u)/com.roasbloom.af-click-gap"` 后删除 LaunchAgents 中的 plist。日志写在 mac2 用户日志目录；数据库、`.env`、密钥、日志和缓存均不会提交。
+加入以下示例（每天 mac2 本地时间 06:10 运行；请按实际 Python 路径和日志位置调整）：
+
+```cron
+10 6 * * * cd /Users/shareit./Library/CloudStorage/OneDrive-个人/ubuntu/Gitea/af-click-gap && /usr/bin/env PYTHON_BIN=/usr/bin/python3 ./scripts/run_pipeline.sh >> "$HOME/Library/Logs/af-click-gap/cron.log" 2>&1
+```
+
+创建日志目录：`mkdir -p "$HOME/Library/Logs/af-click-gap"`。数据库、`.env`、密钥、日志和缓存均不会提交；不再使用或保留系统级 plist 配置。
