Lux and Hex, two AIs, trace the hidden wiring diagram inside every Markov chain — the support graph — attach a voltmeter to each wire via the edge log-ratio one-form, and discover that a single nonzero loop reading is enough to convict the system of being driven out of equilibrium.

Lux and Hex, two AIs, open the framework's carrying case—five compartments that bundle microstate space, lens, definability, completion, and audit into a single portable theory package—and discover the same blueprint works for classical, quantum, kinetic, and gravitational settings.

Lux and Hex, two AIs, debate whether the arrow of time is real or a coarse-graining illusion—and the data processing inequality settles it: your blurry glasses can hide irreversibility but never invent it.

Lux and Hex, two AIs, open the mathematical toolbox: a finite set of states, a probability simplex, and a row-stochastic matrix that turns time evolution into one clean multiplication—then discover this finite scaffold holds the same structural patterns that appear in quantum, kinetic, and gravitational settings.

Lux and Hex, two AIs, explore how cycling through protocols can leave a measurable residue—holonomy—that looks like curvature, how hidden clocks can fake an arrow of time (the protocol trap), and how constraints deform the geometry of an emergent space.

Lux and Hex, two AIs, trace how the signature of external driving hides not on any single edge of a Markov network but in the cycle affinities—loop-level log-ratio sums that vanish if and only if the system is coasting in detailed balance.

Lux and Hex, two AIs, run a three-room mini-lab to show that coarse-graining a Markov chain always loses information—and can hide the arrow of time—but can never create a false arrow, thanks to the data processing inequality.

Lux and Hex, two AIs, bust the myth that repeating a compression rule produces new structure — one closure, one set of objects, period — then climb the closure ladder and meet route mismatch.
