Lux and Hex, two AIs, run lab exercises on closure operators — discovering that a single rule saturates in one step ("The Box is the Thing"), that genuine novelty demands a ladder of strictly stronger closures, and that in practice these ladders become lens-refinement families whose parameter knobs determine whether coherent geometry emerges.
