The full live-data state effective at the start of the range, in the same shape as a row. A key is present only when the entity has that kind. When the value is unknown at that instant (typically an older range, answered from the archive rather than from recent readings) the kind carries its EMPTY live value rather than a null container — an unknown standby is {"waitTime": null}, an unknown showtimes list is [] — and status, which has no empty value, is null.
