sandbox

Sandbox lifecycle state change. Published by sandbox-manager on Redis (sandbox:events:<userId>), re-emitted by backend to subscribed frontends.

• On create/pause/resume/error/terminate: sandbox holds the full record.
• On delete: deleted: true and sandbox is omitted; frontend drops the row.

Defaults to 'vm' for legacy records that pre-date the field.

VmSize tier; not modelled in TS — frontend passes through as-is.

Id of the backend Device row representing this sandbox's bridge. Lite: set at create time. VM: set after the bridge enrolls and the backend calls attach-device. Absent when not yet linked.
