# PowerShell Core / .NET 编译路径。非常量:把程序框架编成托管负载程序集(payload.dll,内含 main.ps1 资源),Brotli 压缩成 "main" 资源塞进 launcher(pack.cs + CoreHost.cs 引导),dotnet publish 成单文件 exe;SMA 不打包,运行时由 CoreHost 从 $PSHOME 解析。常量:constexpr.cs 自包含、不引用 SMA,直接 publish 成单文件 exe,不走 payload/launcher。产物是框架依赖:目标机器需要有 PowerShell Core(提供引擎与模块)以及匹配的 .NET 运行时。
