Platform Compatibility & Build Constraints +`wg-wrap` is fundamentally a Linux system tool. To ensure the module remains compilable on other platforms while restricting Linux-specific syscalls, we use the following patterns: + +- **Build Tags**: All files interacting with `golang.org/x/sys/unix`, network namespaces, or TUN devices must start with `//go:build linux`. +- **The Stub Pattern**: For any platform-specific logic in `internal/`, we provide a matching stub file tagged with `//go:build !linux`. This allows the project to compile on non-Linux OSs, returning "not supported" errors at runtime rather than failing at build time. +- **Platform Agnosticism**: `pkg/` libraries (e.g., `pkg/wgconf`) must remain platform-agnostic and avoid any OS-specific imports to ensure they are reusable across all environments. + +### 4.
