Architecture · one design, six axes · every figure read from this kit's own run
One order. Six lenses.
The picture never moves.
This is the whole of one question — “what was the billed total on ORD-4400, as of 8 March?” — drawn once, as the system that answers it. It is not six diagrams. It is one diagram and six lenses, and each lens measures something on it that a flow chart has no axis for: what it costs, which of the two clocks it is on, who may read it as of the date asked about, what code derived against what was said, which of the estate’s 42 request stages this design leans on, and the doors it refuses to open. Pick a lens. The boxes stay where they are.

What this is
One worked question — “what was the billed total on ORD-4400, as of 8 March?” — and the whole of the system that answers it, drawn once as eleven boxes. Every figure you will see is read from this kit’s own run records, not typed onto the page.
What you are about to watch
Press Play and it moves stop by stop. The eleven boxes never move: each stop lights the ones it is about, redraws the band underneath to whatever that lens measures, and says in words what just happened. The arrows step it by hand; any lens on the rack jumps straight to it.
What the six lenses are for
A flow chart has no axis for what a design costs, which of two clocks it is on, who may read it as of the date asked about, what code derived against what was said, which request stages it leans on, or the doors it refuses to open. One lens per axis, over one unchanging picture.
What you should come away knowing
Ten of the eleven stages are pure code and cost $0.00; a single model call is the entire bill — $0.019750 for the whole measured run. And it is not a clean win: on the guardrail half the paid arm scores 56 of 57 where every free arm scores 57. That is published, not hidden.
Play runs the stops of the lens you are on · ← → step one at a time · pick any lens on the rack below to jump to it · two boxes open a second level when you get there.
Two stages open a second level — use a button, or double-click the box.
