The CrossDomain.TwoCubeUniversality module defines 2³-structure as the property that a type has cardinality exactly 8. It verifies this for DFTMode, Q3Vertex, PauliElement, and TickPhase to show the eight-tick octave appears across domains. Researchers cite it to ground the T7 step of the forcing chain in concrete examples. The module uses direct cardinality computations for each case.

claimA type $T$ has $2^3$-structure if and only if its cardinality satisfies $|T| = 8$.

background

The module sits in the cross-domain layer and relies on Mathlib for cardinality. It introduces the predicate that a type T has 2³-structure precisely when |T| equals 8. This matches the period required by the eight-tick octave in the unified forcing chain. Sibling results then confirm the property holds for the listed structures from DFT, Q3, Pauli, and tick phases by exhibiting explicit 8-element listings or bijections to a standard 8-set.

proof idea

This is a definition module, no proofs.

why it matters in Recognition Science

This module advances the Recognition Science program by demonstrating that 2³-structure is universal across the listed domains, thereby supporting the forcing of the eight-tick octave at T7. It supplies the concrete 8-element sets needed for applications of the mass formula and Berry creation threshold. The equicardinal and powerset results extend the basic definition to related constructions.
