## Description

Maintain and validate OpenShell's native Windows MSVC and MXC runtime lane for x64 and ARM64. Use when working on Windows compilation, `windows:*` mise tasks, the MXC supervisor/sandbox pairing, unsupported Windows compute-driver contracts, or Windows build reports. This skill does not implement Docker, Kubernetes, Podman, VM, MSI, or service support on Windows.

# Build OpenShell-MXC for Windows

This skill maintains the existing native Windows MSVC build lane in the
OpenShell repository's [`windows` branch](https://github.com/NVIDIA/OpenShell/tree/windows).
That branch owns native Windows implementation and releases. Shared docs may
also appear on `main`; always direct Windows work to `windows` and use explicit
Windows branch links for implementation details. See
[Native Windows support](https://github.com/NVIDIA/OpenShell/blob/windows/WINDOWS.md).

Before running the tasks below, use a `windows`-based checkout and read the
[skill from that branch](https://github.com/NVIDIA/OpenShell/blob/windows/.agents/skills/build-openshell-mxc-windows/SKILL.md).
The task and runtime descriptions refer to that checkout, not to any older
Windows source snapshot retained on `main`.

The lane validates that OpenShell can compile and test on Windows MSVC for the
supported deliverables:

- `openshell-gateway.exe`
- `openshell.exe`
- `openshell-supervisor.exe` (host RFC 0012 isolation backend)
- `openshell-windows-sandbox.exe` (MXC ProcessContainer boundary)

It intentionally does not make Windows a Docker, Kubernetes, Podman, or VM
runtime host.
