Test whether Q8 junction pairs support a repeatable local 2→2 material mechanism

physical material
mechanism
experimental

Open problem

Can selected Q8-classified trivalent junction pairs be prepared and driven so that the same typed local input and boundary repeatedly yield one 2→2 output?

Why it remains open

The cited laboratory work establishes rich defect structure and driven reconnections, not the conjectured deterministic pair-local mechanism.

Scope

Chiral-nematic samples, typed junction preparation, declared boundary conditions, non-pair-selective global electric drive, and repeat trials.

Next discriminating criticism or test

Blindly repeat matched preparations while varying remote graph context; failure of output invariance criticizes the proposed local mechanism.

Chiral-nematic typed-junction 2-to-2 interaction-net rewrite

Prepare the same typed local pair and boundary repeatedly, blind the operator to remote graph context, apply the declared global drive, and test whether the output topology is invariant to remote context.

Strongest falsifier: Output class changes systematically with remote context while local pair and boundary are held fixed.

OAM angular collision/interference and contraction variant

Collide two independently prepared OAM/multimode wave packets with controlled relative phase and angle, and discriminate a local angular-interference/contraction rule from linear superposition and detector artifacts.

Strongest falsifier: The signature is fully explained by linear interference, alignment, or detector cross-talk.

Equipment capabilities: phase-resolved multimode field analyzer
