The Zipper Whose Hole Is a Universe
Execution state is a zipper — the present moment is not a parameter or a modality but a universe that separates tropical past from predicate future. Tic-tac-toe makes the structure visible.

The Incidence Reduction
ODE steady-state values with uniform rates reveal integer structure — incidence degrees to terminal transitions — giving a reverse-engineering technique for rate constants.

Tic-Tac-Toe Model
Modeling tic-tac-toe using Petri nets with ODE simulation for AI move selection—no game heuristics, just model topology.
