fn queue_remove_row(value: &Value) -> Option<SessionMessage>Expand description
The queue-operation remove line as the queued prompt’s row, or None
for any other line.
The remove is the start. The CLI writes it when it takes the prompt
out of its queue - at the end of the turn that was running, or absorbed
into it - so the row’s clock is that removal, not the press. Only a
reason in START_REASONS takes the prompt.
