# deploy/toggle_bioflow_176.sh —— 176 生信模块快速开关(off/on)
# 用法(在 176 上执行,或从 175 ssh 过去执行):
#   bash /srv/plantai/toggle_bioflow_176.sh off   # 关生信:env=false + 重启 BFF → 生信 TAB/入口消失
#   bash /srv/plantai/toggle_bioflow_176.sh on    # 开生信:env=true  + 重启 BFF → 生信 TAB 恢复
# 原理:BFF main.py 按 BIOFLOW_ENABLED 决定是否注册 bioflow 反代路由;
#       不注册时 /api/bioflow/health 返回 404,前端 probe 落 offline,生信 TAB 自动隐藏。
