Lifecycle state

A device's lifecycle state is its operational status, as opposed to its live connection state.

• ACTIVE — in service; the default device-list view shows only active devices.
• QUARANTINED — reversibly locked by quarantine.
• Decommissioned/archived states are tombstones: devices are never physically deleted, so history and identity remain auditable.

Lifecycle is independent of presence: an active device may be offline, and connectivity says nothing about whether the device is in service.
