四处"校验在错误的层"的缺陷,都属于同一类:每个组件单独看都对,接缝错了。 1. `msa-agent enroll --relay http://relay.example` / `relay.example` / `https://relay.example/v1` 都会写出配置文件,install 报成功,守护进程在**下一次启动**才 拒绝,日志里只有一行 "msa-agent exiting"。规则原本散在三处(config 只查非空、transport 查真实规则、enroll 的注册客户端另有一份),现在收进 `internal/relayurl` 一份,三处都调它。 `config.File.Validate` 因此也补上了 https/host/无路径/无 query 的检查。 2. `enroll` 不再自己手写字段检查,改为构造真正的 `config.File` 并调用真正的 `Validate`—— 一份"什么是可用配置"的定义,结构上无法再漂移。`config.Marshal` 让 enroll 与 Save 用同一个 编码器。 3. `install --config /srv/msa/config.json` 会给该文件改属主、交给服务用户,然后写一个 ExecStart 指向 `/etc/msa-agent/config.json` 的单元——服务起来找不到配置就退出,而它需要的 文件就在别处、属主正确、从未被读。`enroll --audit /srv/audit/audit.log` 同理:单元的 `ReadWritePaths` 只覆盖 `/var/log/msa-agent`,在 `ProtectSystem=strict` 下 agent 的 `MkdirAll` 报 EROFS,进程启动即退出,报错既不提那个 flag 也不提那条指令。现在单元是模板, `RenderedUnit` 按实际布局渲染,`--print-unit` 打印的就是会被写入的那一份;默认布局渲染结果 与仓库里被 review 过的文件逐字节相同,所以 vendored 副本的漂移检查仍然有意义。 测试:新增 `internal/relayurl`,`config`/`enroll`/`install` 各补回归测试。每条都做了变异验证 (把修复回退,对应测试必须失败)。
