ReadonlyidThe device id (stagebox id / soundcard name / surface id).
ReadonlyinputHow many restored channel input patches feed from this absent device.
ReadonlykindReadonlynameHuman label for the operator (the stagebox name + model, the card, the surface type).
ReadonlyoutputHow many restored bus output routes feed to this absent device.
ReadonlysummaryThe English log rendering of summaryParts, and the fallback for an older client.
ReadonlysummaryThe "what depends on it" clauses as translatable CODES, in reading order — what a surface
renders (joined with hardware.missing.clause-separator, wrapped by
hardware.missing.summary). Never prose: the counts, the NIC and the device name are
parameters, so a locale writes its own sentence around them.
One absent expected device + what the restored session depends on it for (issue #154).
