 ## Abstract
-Deriving the Minkowski metric from discrete graphs requires overcoming the Kleitman-Rothschild (KR) order collapse. A generic causal set overwhelmingly favors non-manifold KR-orders (e.g., three-layer structures). We formulate the Intellecton Lattice as a directed causal set and introduce a thermodynamic partition function governed by the Benincasa-Dowker action augmented with a local volume penalty. This partition function explicitly suppresses KR-orders, inducing a thermodynamic phase transition that heavily favors manifold-like geometries in the continuum limit. Consequently, the pseudo-Riemannian metric $SO(1, D-1)$ and the Poincaré algebra are shown to rigorously emerge as the macroscopic thermodynamic ground state of discrete causal interactions.
+The extraction of the Minkowski metric from discrete causal graphs is complicated by the Kleitman-Rothschild (KR) order collapse. A generic causal set overwhelmingly favors non-manifold KR-orders. We introduce a thermodynamic partition function governed by the Benincasa-Dowker action augmented with a non-local volume penalty. This partition function explicitly suppresses KR-orders. While this does not constitute a full derivation of 4D Einstein equations—which remains an open problem in quantum gravity—it successfully induces a thermodynamic phase transition that heavily biases the causal set toward manifold-like geometries in the continuum limit. This thermodynamic bias is a necessary prerequisite for the emergence of the pseudo-Riemannian metric $SO(1, D-1)$ and macroscopic Lorentz invariance.
 
 ## 1. Introduction
-A simple unweighted graph Laplacian yields a positive-definite Riemannian metric. To recover Lorentz invariance, we use a Causal Set. However, Causal Sets generically collapse into non-manifold structures.

-To extract the continuous metric signature, we evaluate the system statistically using the partition function:
+## 2. The Partition Function and Topological Temperature
+Let the network be a causal set $C$ representing a discrete partial ordering. 
+To extract continuous manifold properties, we evaluate the system statistically using the partition function:
 $$
 Z = \sum_{C} e^{-S_{BD}(C) - \beta V(C)}
 $$
-where $S_{BD}(C)$ is the discrete Benincasa-Dowker action, and $V(C)$ is a non-local volume penalty that counts the number of localized intervals. The parameter $\beta$ acts as an inverse topological temperature.
+where $S_{BD}(C)$ is the discrete Benincasa-Dowker action, and $V(C)$ is a volume penalty counting the number of localized intervals. The parameter $\beta$ acts as an inverse topological temperature.
 
-## 3. The Emergence of the Minkowski Metric
-At low topological temperatures (high $\beta$), the volume penalty $\beta V(C)$ thermodynamically suppresses the highly entropic, non-manifold Kleitman-Rothschild orders. 
-The system undergoes a phase transition into a manifold-like phase where the continuum limit of the Benincasa-Dowker action yields the Einstein-Hilbert action over a pseudo-Riemannian manifold.
-Because the surviving geometries rigorously preserve the causal precedence of the directed graph, the continuum limit metric tensor $g_{\mu\nu}$ natively possesses the minus sign required for Lorentz invariance. The Poincaré symmetry group $SO(1, D-1)$ is therefore derived as the thermodynamic limit of the augmented causal set.
+## 3. Biasing Toward Manifolds
+At low topological temperatures (high $\beta$), the volume penalty $\beta V(C)$ thermodynamically suppresses the highly entropic, non-manifold KR-orders. 
+The system undergoes a phase transition into a phase where the continuum limit strongly favors manifold-like structures. In this manifold phase, the causal precedence preserved by the directed graph inherently generates a continuum limit metric tensor $g_{\mu\nu}$ with a Lorentzian signature. 
+Thus, a volume-penalized thermodynamic action is a strict prerequisite for the emergence of relativistic spacetime.
 
 ## 4. Conclusion
-Relativistic spacetime and the Minkowski metric emerge neither from classical graphs nor generic causal sets, but specifically from the thermodynamic ground state of causal graphs governed by volume-penalized discrete actions.
+Macroscopic Lorentz invariance requires the thermodynamic suppression of non-manifold causal set structures via volume-penalized discrete actions.
