EDOC Addendum II — Arrow and Carrier Principle

This addendum extends the operator formalism defined in EDOC Addendum I by specifying the mechanism of informational transfer between causal operators E, D, O, and C. Each arrow (E → D → O → C → E) represents causality-in-motion and requires a carrier that conveys energy and information during transformation. A dimensionless coherence parameter Ωᴱ is introduced to quantify causal coherence per frame. The principle preserves informational closure without adding new physical parameters, bridging the mathematical environment of Addendum I with empirical interpretation and establishing the basis for later causal metrics.Clarification (Nov 2025):The sentence “The continuum remains closed only when all arrows complete without loss of coherence” describes the ideal vacuum-limit condition (Ωᴱ = 1).Later addenda (III–IV) extend this to operational closure, where realized efficiency ηₚ < Ωᴱ and information remains conserved.This note clarifies interpretation only; no theoretical or mathematical change is introduced.
