Deterministic origin-cube open/closed bridge #

This file keeps the deterministic cube/open-cube equivalences needed by Chapter 2 and coarse-graining. The old probability-facing annealed wrappers around these facts live only in the legacy probability archive.

Deterministic bridge data from the half-open origin cube to the corresponding open cube at scale n.

This isolates the only genuinely domain-sensitive missing theorem needed to transport the Chapter-4 symmetry argument from the literally invariant open cube back to the currently defined half-open at-scale objects.

Instances For

    Arbitrary-triadic-cube version of the open/half-open admissibility bridge for the doubled Mu problem.
