Module viewer_devices 

Paired devices: the viewer grants a device receives at pairing, and each agent’s “hide from paired devices” flag. See db_viewer_devices and db_agents.hide_from_devices in migrations.rs (OBJECT_SCHEMA_VERSION v43) and backend::viewer.

A device’s token is never stored, only its SHA-256 (lowercase hex), so a copy of this database opens no feed. Revoking deletes the row.

Structs

ViewerDevice

One paired device, as Settings lists it. Never carries the token hash.
