Theorem R.1 — Emergent Causality

In any dissipative system that supports horizon-robust inertial organization, there exists a finite, observer-independent maximum speed of coherent influence $c_{\mathrm{eff}}$. No influence propagating faster than $c_{\mathrm{eff}}$ can retain phase coherence or dynamical relevance.

This theorem supplies the causal backbone traditionally attributed to spacetime structure, but derives it from dynamics alone.
