## FAQ

### Does it require inbound ports to be open?

No, the node dials out to a hub, meaning the machine opens no inbound ports and no SSH is required.

### How does it handle long-running processes?

It supports durable sessions that survive connection drops, hub restarts, or client disconnects using byte offsets for polling.

### Is the execution secure?

The link is mutually authenticated with HMAC-SHA256 over TLS, and every tool call can be recorded in a tamper-evident audit log.

### What operating systems are supported?

It is built and tested for Linux, macOS, and Windows.
