A fibre-bundle model with dual spacetimes (smooth manifold plus causal set) derives relative locality in general PQG theories without requiring momentum-space curvature.
Introduces the order-theoretic property of conicality for space-times and proves a correspondence between conical space-times and faithful information-theoretic causal models under no-superluminal-signalling constraints.
LCC models observer consistency via coupled C and O operators on causal DAGs, producing a readability order that factors when ordering does not refine causality and placing classical results as (C,O) configurations.
Proposes a causal EPRL spin-foam model where the two-complex orientation encodes causality and aids semiclassical geometry reconstruction.
