EDOC Addendum III — Causal Metrics Definition

This addendum extends the Arrow and Carrier Principle (Addendum II) by defining quantitative metrics for the EDOC continuum. It introduces the causal-realization rate Γ (frames per second) and the frame-information quantity X_EDOC (bits per frame), and formalizes an empirical efficiency ηₚ constrained by the coherence ceiling parameter Ωᴱ (previously defined in Addendum II). These quantities express how fast causal frames are realized, how much information each frame commits, and how efficiently that process preserves coherence. Together they define the minimal causal metric set {F, Γ, Ωᴱ, X_EDOC} for quantitative EDOC.
