Add a Box API key in App Settings to provision an isolated hosted Linux desktop. The computer can sleep and wake, and supported sessions provide a live viewer for temporary human control. Trial accounts automatically retry creation with the provider's shorter auto-stop ceiling when required.

Box is a third-party paid service after its trial. OpenMausBot stores the configured credential locally and does not expose it to the renderer.

This permission is off by default. When neither the VPS nor a local fallback is available, OpenMausBot shows the exact VPS failure instead of silently omitting computer tools.

OpenMausBot can turn a Linux server you already own into a bot's computer. The agent process stays on your
machine; Docker's own SSH transport reaches the daemon on the VPS, and each bot gets one managed, hardened
Cua container there — a Linux desktop it can see and control. SSH is the only credential involved and the
only surface exposed: OpenMausBot never opens a port on the VPS, never stores a key or password, and never
runs an agent remotely.

## What works

- A per-bot Linux desktop in a managed container on your VPS, driven through the official Cua tools.
- Live screen preview in the Computer panel and in transcripts, same as a Box.
- Explicit **Cloud** with the **Self-hosted VPS** backend provisions or starts the container; **Auto** only
reuses one that is already running and verified.

Deliberately not offered: an interactive desktop tunnel. There is no "Open desktop" for a VPS bot — the
container publishes no ports, so there is nothing to tunnel to, by design.
- Explicit **Cloud** with the **Self-hosted VPS** backend provisions or starts the container. **Auto** reuses
a ready container by default; an off-by-default **Start VPS automatically** switch lets that bot prepare
or wake its managed container when needed.
- Interactive **Take control** through a temporary SSH tunnel. The app binds noVNC only to a random
`127.0.0.1` port on your computer, closes the tunnel with the viewer, and never publishes VNC on the VPS.

Release the blocker when the sidecar exits.

The sidecar exit handler only clears proc and logs the exit. If CompanionSection is unmounted, its polling stops, so no companion:state call reaches syncCompanionKeepAwake(false, false). Call it from the sidecar exit handler.
