In plain English
What is this thing?
One card has a plain edge, one has a round hole and one has four square notches. They distinguish an interval never probed, a probe whose trace was not retained, and measured time deliberately left open.
The tray makes these differences inspectable. It cannot ensure that a later reader remembers all three distinctions.
