The Registry Mechanism Scaling Causal Measure Space to Cosmological Latency

We propose a formal correspondence between the Temporal Selection Framework (TSF) and the Causal Action Principle (CAP) of Felix Finster. We define a Registry Conjecture wherein the universal measure (µ) of a Causal Fermion System represents the discrete state-space of the Registry. We identify the Registry Latency (λ) as the source of the Hubble Tension, arising from a “Synchronization Lag” inherent in the minimization of the causal action across expanding distances. We provide a primary falsifiable prediction: the decay of λ as a function of redshift z toward the early-universe limit
