# maka-sandbox

[简体中文](README.zh-CN.md)

Prepares authorized commands for operating-system isolation. The Host decides permission and owns execution records; this crate applies filesystem and network restrictions. Process I/O and lifetime belong to [maka-process](../process/README.md).

macOS uses Seatbelt, Linux uses bubblewrap and network namespaces, and Windows uses provisioned low-privilege accounts, WFP rules and Jobs. Linux requires bubblewrap 0.11 or newer at `/usr/bin/bwrap`. Unsupported policies fail before execution. Windows setup is explicit through `maka sandbox setup --root PATH`; the Host remains unelevated.

Destination-restricted traffic passes through an execution-owned gateway. Routing and credentials stay with the Host, and redirects need their own destination permission. Linux and Windows expand deny globs before launch; future matching paths are covered on a subsequent launch, not by that existing snapshot.

To exercise a policy with the production backend:

```sh
maka sandbox run --policy policy.json --cwd /absolute/workspace --command 'your command'
```

On Windows, also pass the configured `--root`. A read-only policy with no network is:

```json
{"kind":"managed","filesystem":{"default":"read","rules":[],"denyGlobs":[]},"network":"denied"}
```

Use `maka sandbox --help` for setup, status and removal. These controls constrain model-directed effects; trusted native plugin code runs in the host process.
