History

These are the events from the Events browser, unrolled. That screen shows each event once, as it stands now; this one shows every revision it has passed through — so you read the arc, not the current state. A row is a revision, carries its rev n, and opens the same record its counterpart on Events opens. Absence is recorded as deliberately as onset: "nothing here now" is a fact you can trace to the revision that made it true, never inferred from an empty screen.
