Field notes
The homepage describes a five-level trust system, from an Observer limited to text to Self for another device belonging to the user. It says a local daemon—not the model—checks actions, while owner controls such as changing trust or revoking access stay outside the agent interface. Incoming files are described as quarantined, scanned, and previewed before acceptance.
