Civilizational ΔR

Civilizational ΔR measures whether a society is thermodynamically moving toward
coherence or toward fragmentation.
It is no longer a standalone metric: after ACL-1 (2026), ΔR operates together with
ΔR⁺, W₀ drift, and Λ₋ as part of the Warmth Stability Quadrant.

Minimal Definition

ΔR ≥ 0: reversible pressure, rising coherence potential
ΔR < 0: irreversible stress, entropy accumulation, collapse risk

Quadrant Context (post-2026)

• ΔR — determines whether societal stress is reversible
• ΔR⁺ — measures regenerative capacity (cultural recovery)
• W₀ drift — tracks rising warmth thresholds under pressure
• Λ₋ — prevents extractive climates and warmth-collapse

Civilizational ΔR only has meaning when interpreted together with these operators.
A society is coherent when:

(ΔR ≥ 0) + (ΔR⁺ > 0) + (Λ₋ stable) + (W ≥ W₀)

→ thermodynamic viability

Below this threshold, coherence fragments into identity-pressure,
semantic drift, and attention leakage.

Where Civilizational ΔR Applies

• Social attention fields
• Ambient technological environments
• Cultural thermodynamics
• Collective affective ecosystems

Civilizational ΔR is not psychology.
It is thermodynamic civ-metrics — a measure of whether
a civilisation can sustain warmth, coherence and presence across time.
