/**
|
|
|
|
|
|
* 运行时版本基线巡检（档案 44）。
|
|
|
|
|
|
*
|
|
|
|
|
|
* 目的：**保证实例共享的基础运行时（Python / pip / node / npm）版本稳定**，
|
|
|
|
|
|
* 避免"版本差异导致插件功能无法使用"。
|
|
|
|
|
|
*
|
|
|
|
|
|
* 背景：运行时是平台在 `/usr/local/dsh-runtime/` 装的可移植发行版，
|
|
|
|
|
|
* 实例内 `/usr` 只读 → 理论上改不了；本脚本是**观测兜底** ——
|
|
|
|
|
|
* 一旦版本偏离基线（例：有人在宿主上手动装/换了版本），立刻告警，而不是等插件坏掉才发现。
|
|
|
|
|
|
*
|
|
|
|
|
|
* 用法：
|
|
|
|
|
|
* node runtime-baseline.cjs # 对比，偏离则退出码 1（cron 会记日志）
|
|
|
|
|
|
* node runtime-baseline.cjs --accept # 主动把当前版本写入基线（升级运行时后执行）
