Regime
Kinematics only — an identity about the field, whatever moves it
Every figure drawn under this hypothesis — 37 of them — with the essay each one belongs to and the generator that drew it.
37 figure placements state this regime. The strip along the foot of every figure names two things — the model that produced it and the regime it holds in — and this listing is read back out of the finished drawing rather than from what produced it.
